FOR 018 Predicting The High Risk of Poaching areas Inside Bukit Barisan Selatan National Park Using MaXent. Muhammad Irfansyah Lubis (Wildlife Conservation Society; [email protected]). Conservation areas which are designed to keep endangered species and their habitats protected are highly threatened from illegal poaching activities. Carnivores such as tigers and their prey are threatened by direct hunting for food, curatives or trophies for domestic and international markets. The limited resources from local authorities to battle against poachers are one of the reasons behind the decreasing population of endangered species and their prey. In order to increase the effectiveness of law enforcement and site-based conservation efforts in Bukit Barisan Selatan National Park, we used SMART patrol data to develop a map of high risk of poaching areas. The distribution of high risk of poaching area was identified using Maximum Entropy (MaXent) model. We used bias mask from patrol tract to avoid bias in our model. We found that minimum distance to road at lower elevation is the variable that significantly contribute the most and explain why poaching occurs within this park. In addition, by using different data set from different year, our validation result shows that this predictive map is good to use to effectively monitor the areas where poaching occurs. This will help the managers to plan, evaluate and implement the better anti-poaching effort activities as well as to promote good governance. FOR 019 The Use of Hotspot Spatial Temporal Clustering and Dynamic LUCC to Facilitate Peatland Degradation in Kalimantan, Indonesia (Case Study–Mensiku Miniwatershed of Kapuas River). Iksal Yanuarsyah*, Sahid Hudjimartsu, Yatin Suwarno (Geoinformatics, IT Department; UIKA BOGOR; [email protected]). Mensiku miniwatershed located in upstream Kapuas watershed is one of the water supply and catchment area of Kapuas River. Landsystem of Mensiku miniwatershed is dominated by peat land with cover formation of logged peat forests, tembawang and arable land community. Degraded peatland contains of logged forest and arable land is one of sensitive fire hazards. Hotspot spatial temporal clustering by using kulldorff scan statistic method combined with dynamic landuse and landcover changes analysis using multitemporal satellite imagery (LANDSAT acquisition 2002, 2006, 2009, 2001, and 2016) to facilitate the peatland degradation. This approach is used as early warning for the fire hazard in Kapuas Watershed, Kalimantan. The analysis results show particular hotspot 2 spatial cluster with density values reach 0.7 km in peat forest and peatland were heading moderate to mature peat (Hemists to Saprists) at a depth of 100-300 cm. This inclination occured in forest conversion to non forest uses with degradation over 0, 3 km2 per year. Based on field observations, concentration of burned area Program Book 99

FOR 020 Typology of Land and Forest Fire in South Sumatra, Indonesia. Muhammad Ardiansyah*, Rizaldi Boer, Supiandi Sabiham, Anter Parulian Situmorang (CCROM- SEAP; Bogor Agricultural University; [email protected]) Land and forest fires have become an increasing problem in Indonesia in the past decades and occurred almost every year with varying intensity and burned area. These fire have many adverse environmental, social and economic effects. They affect global carbon dynamics and the haze from peat fires in this region has serious negative impacts on the ecosystem, economy and human health. The intensity of land and forest fires tends to rise in El Niño-Southern Oscillation (ENSO) devasted large areas of Indonesia tropical rain forests (Siegert, et al., 2001). The fires were particularly bad in 2015 because of a prolonged dry season caused by El Nino weather pattern and creating a lot of greenhouse gas emissions. Number of hotspot in the period of July-December is to reach 30,597 and 39,627 points (confidence level ≥0.5) in Sumatera and Kalimantan respectively. The aim of the study was to find burned area that caused by fire activity in 2015 and to identify a typology of land and forest fire the South Sumatera. In our study, between July and December 2015 (El Nino) the estimated burned area in South Sumatera was 424,374 ha, of which 163,404 ha in mineral and 260,970 ha in peat. The majority of burned area occurred outside license and concession and in palm oil plantation and HTI with following typology: the fire activity occurred in the palm oil plantation with forested land, the palm oil plantation with non-forested land, the HTI with forested land, and the HTI with non-forested land. FOR 021 Image-Based Mangrove Leaf Area Index Modelling- A Comparison of Terrestrial Optical Sensors. Muhammad Kamal* (Cartography and Remote Sensing Study Program, Faculty of Geography; Universitas Gadjah Mada; [email protected]). Mapping and monitoring of mangrove Leaf Area Index (LAI) is essential for sustainable mangrove forest management. LAI is a key forest indicator for quantifying energy and mass exchange by plant canopies over landscapes. Remote sensing technology has proven to be effective to indirectly derive the LAI information, especially in mangroves environment where sometimes inaccessible. Most of the studies in LAI mapping utilised semi-empirical models based on the relationship between pixel values and in-situ measurement. The accuracy of the in-situ measurement is therefore critical. This paper compares and contrases the accuracy of the LAI models derived from the standard LiCOR LAI-2200 instrument and the low cost Digital Hemispherical Photography (DHP) in mangrove environment, and evaluate the map resulted from the models applied to WorldView-2 image. The research was conducted in Karimunjawa Island mangroves with high variety of mangrove species and tree structure. Preliminary results indicate a low correlation (R2=0.41) between the LiCOR LAI-2200 and DHP. Program Book 100

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 The low correlation was possibly attributed to the positional error of the sample points and inaccuracy in defining the DHP processing parameters. However, the estimated LAI value pattern from both models across the sample points is generally similar. This pattern also evidence from both LAI distribution map results. The results show that low cost DHP is sufficient for estimating mangrove LAI. Further study needs to be conducted at different mangrove sites to assess the consistency of the result. FOR 022 Assessments of Sentinel-2 and Landsat-8 Spectral Capabilities in Determining Forest Stand Parameters. Muhammad Buce Saleh, Edwine Setia Purnama* (Dept. of Forest Management; Faculty of Forestry; Bogor Agricultural University; [email protected]) The advance of remote sensing technology has led to methodological improvement in forest inventory. Numbers of recent satellite images offer better spectral, spatial, radiometric, and temporal resolutions. In particular, Sentinel-2 and Landsat 8 have similar spectral characteristics and claimed to provide better detection on vegetation. However, the reliability of those images to determine forest stand parameter has not been fully assessed. Therefore, it is necessary to conduct an assessment of the spectral capabilities, particularly in forest management. The objective of this study is to assess the capabilities of spectral characteristics of Sentinel-2 and Landsat-8 satellite images in determining forest stand parameters i.e. stand density, basal area, volume, and above ground biomass. In this study, vegetation-related bands are used as the main satellite image variable. Meanwhile forest inventory result of dry land forest in Kapuas and Murung Raya regency are used to obtain forest stand parameters. Relationship between either original bands or vegetation indices and field measurement are evaluated. In this regards, statistical measures are used as criteria for the assessment. FOR 023 Mapping of Invasive Species (Arenga obtusifolia) in Javan Rhinos Habitat, Ujung Kulon West Java, Based on Landsat-8 Image Analysis and Geographical Information Systems. Projo Danoedoro*, Muhammad Hafizt, Dimar W. Anggara, Ikhsan Wicaksono, Rahardian Kuncara, Hernandea Forestriko, Rois Mahmud (PUSPICS Faculty of Geography; Universitas Gadjah Mada; [email protected]) Javan rhino is a unique, endangered species that could only be found in the west tip of Java Island. There are only about 50 individuals surviving in their natural habitat in Ujung Kulon National Park (UKNP). The increasing distribution of an ‘invasive’ species called langkap palm (Arenga obtusifolia) becomes prominent in relation with the decrease of natural vegetations that serve as rhinos’ food. The langkap palm has been spreading out over the past 30 years, and its distribution needs to be mapped accurately, since the palm’s spatial distribution may help habitat management policies. This study tried to map the langkap palm’s spatial Program Book 101

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 distribution using two approaches. Firstly, we used landscape ecological approach in mapping the langkap palm by collecting field data of its frequency in relation with several terrain characteristics. Spatial interpolation techniques were explored to map the spatial distribution of the terrain characteristics, and the results were correlated with the langkap palm frequency distribution. Secondly, we used vegetation index and multispectral classification. The vegetation indices were used to predict the langkap palm’s frequency based on regression analyses, while the multispectral classification was utilised to map the langkap palm based on its spectral characteristics. We found that the multispectral classification method could map the A. obtusifolia spatial distribution more accurately, i.e. 91%. The other methods did not successful due to the number and distribution of samples, as well as the characteristics of the invasive species, which are not highly correlated to the terrain characteristics in the study area. FOR 024 The Effect of Image Radiometric Correction on The Accuracy of Vegetation Canopy Density Estimates Using Several Landsat 8 OLI’s Vegetation Indices: A Case Study of Wonosari Area. Rizky Pranata Dewa, Projo Danoedoro* (PUSPICS Faculty of Geography; Universitas Gadjah Mada; [email protected]) Recent studies on the use of spectral indices have involved radiometric correction as a prerequisite. However, study on the effect of radiometric correction level on the accuracy of biophysical parameters’ estimate is still rare in Indonesia. This study tried to investigate the influence of various radiometric correction levels and the number of vegetation strata on the accuracy of vegetation density estimates using NDVI, MSAVI2 and GEMI of Landsat 8 OLI. In this study, the dataset covering vegetated area in Wonosari, Gunung Kidul Regency, Indonesia was processed radiometrically using eight different methods, i.e. spectral radiance, at sensor reflectance, sun elevation correction, histogram adjustments using original DN, spectal radiance, at sensor reflectance, and sun position correction respectively, as well as dark object subtraction (DOS). Every image with specific correction level was then transformed using the aforementioned indices, in order to be correlated with the field-measured canopy density. The analyses were carried out by considering the number of canopy layers. This study found that different radiometric correction methods resulted canopy density estimates with different accuracies. In addition, the number of canopy strata also played an important role. Every vegetation index transformation performed its best accuracy by using different radiometric correction method and for different number of canopy layers. FOR 025 Soil Erosion and Its Correlation with Vegetation Cover: An Assessment Using Multispectral Imagery and Raster-Based GIS. Diwyacitta Dirda Gupita*, Sigit Heru Murti B.S. (Remote Sensing Department; Faculty of Geography; Gadjah Mada University; [email protected]) Program Book 102

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 Soil erosion in caused by five factors: rainfall erosivity, soil erodibility, slope and slope length, crop management, and land conservation practices. In theory, vegetation as one of the affecting factors has inversed correlation with soil erosion. This research is aimed to: (1) model RUSLE using pixel-based GIS, and (2) prove whether or not vegetation really has the said correlation with the soil erosion that occurs in Gesing Watershed. The method used in this research is divided into two: the use of RUSLE to estimate the soil erosion rate; and the use of fractional vegetation cover (FVC) formula to estimate the vegetation density in the area. Both methods used Landsat-8 OLI imagery, which is used to extract the RUSLE parameters as well as to derive the vegetation density through NDVI, and pixel-based GIS. The mapping of soil erosion rate distribution done in this research demonstrated that pixel-based modeling is able to represent a much more detailed and logical distribution of a phenomenon, because every point, in this case pixel, has a value of soil erosion rate. The distribution of soil erosion rate in Gesing Watershed showed that the erosion rate in this area is relatively minor. About 1425.99 hectares and 1587.57 hectares of the total area have erosion rate of 0 – 15 tons/ha/yr (very mild) and 15 – 60 tons/ha/yr (mild) respectively. The descriptive analysis of how soil erosion rate correlates with vegetation cover showed that areas with high vegetation density do not necessarily have low erosion rates. FOR 026 Spring Maintenance Strategy through Revitalization in Wonosadi Forest, Beji Village, Ngawen District, Gunungkidul District, Yogyakarta. Theresia Retno Wulan*, Wiwin Ambarwulan, Etik Siswanti, Sukma Impian R (Geospatial Information Agency; [email protected]) Wonosadi Forest located in Beji Village, District Ngawen, Gunungkidul Regency, and Yogyakarta Special Region which is located in the hills Structural physiographic Baturagung generally utilize springs to meet daily needs. The existence of water resources need to be preserved to prevent the occurrence of drought and environmental degradation. The purpose of this study is to assess the condition of Wonosadi Forests, particularly about the potential springs and explore the various indigenous communities related to the management Wonosadi Forest springs. The research method consisted of a literature study, field review, and interviews with relevant parties Wonosadi Forest. Wonosadi Forest consists of a conservation zone and a buffer zone. Springs contained in the Forest Wonosadi are springs Kalas, Blebem springs, and springs billowing. The third springs belong to the perennial springs that flows throughout the year. Kalas springs, Blebem and billowing forest area conservative. Forms of local wisdom in the Forest Wonosadi basically a form of do's and don'ts. In the preservation of the environment, local knowledge is no longer regarded as a superstition, but people have been taught about the wisdom and the wisdom to behave in a correct understanding.

Siti Badriyah Rushayati*, Rachmad Hermawan, Resti Meilani (Bogor Agricultural University; [email protected]) Oil palm plantation has often been accused as the cause of global warming. However, along with its growth, it would be able to decrease surface temperature. The question is ‘when will the plantation be able to reach the same surface temperature as natural forest’. This research aimed to estimate the age of oil palm plantation that create similar surface temperature to those in natural forest (land cover before the opening and planting of oil palm). The method used in this research was spatial analysis of land cover and surface temperature distribution. Based on the spatial analysis of surface temperature, five points was randomly taken from each planting age (age 1-15 years). Linear regression was then employed in the analysis. The linear regression formula between surface temperature and age of oil palm plantation was Y = 26.002-0.1237X. Surface temperature will decrease as much as 0.1237? C with one year age growth oil palm. Surface temperature that was similar to the initial temperature, when the land cover was natural forest, was estimated to occur when the oil palm plantation reach the age 23.95 year. FOR 028 Assessing Burn Severity during 2015 Forest Fire in Way Canguk Research Station, Bukit Barisan Selatan National Park, Lampung, Indonesia. Muhammad I. Lubis*, Laji Utoyo, Eunike L. Immanuella, William Marthy (Wildlife Conservation Society; [email protected]) Forest fires have become a seasonal phenomenon in Indonesia especially during Dry Season. The prolonged El Nino event in 2015 has devastated the majority of forest and land in Sumatra and Kalimantan, killed at least 19 people and approximately 500,000 cases of respiratory tract infections have been reported, as well as destroyed vast amount of wildlife habitats. In Southern Sumatra, we conducted a study to estimate burnt scars in the remaining lowland forest in Bukit Barisan Selatan National Park (BBSNP). The difference in Normalized Burn Ratio (dNBR) before and after the fire event were calculated from Landsat 8. Field validation was conducted a few months after the fire incidents and measured the fire severity to the forest. Vegetation species that affected by fire were collected, as well as the seeds that grow after the fire. This information will be useful to map the fire location and burn severity and identifying potential activities to save the remaining wildlife and vegetation. FOR 029 Bio-Vegetasi Method (Bioveg): Improved Land Mine Closure Methods Effective and Efficient and Environmentally Friendly.

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 The mining industry either mineral or coal scattered in Indonesia has now quite a serious impact on the ecosystem and the environment. In addressing these conditions, has done much soil remediation efforts by the parties concerned through the reclamation of land mines, but results have been achieved has not been maximized. During this time constraint in reclamation by the re-vegetation is quite diverse, one of which is a steep slope of the land due to mining activities and infertile soil, where the condition is vulnerable to erosion event occurred. Bio- Vegetasi Method (Bioveg) present as a solution to overcome the failure of mined land reclamation that we have seen before in any mining. Bioveg is made through the use of legumes Desmodium heterophyllum and designed like a carpet square shape with an area of 40 cm x 40 cm each. Another benefit of using reclaimed media can be used in all soil conditions, such as peat, sand land, land heath, acid- soaked land, land with a soil pH that is different, and other types of land. As a media substitution of high quality, effective, and efficient, as well as have the ability to fertilize the soil is low nutrients, Bio-Vegetasi Method (Bioveg) potentially to be developed and used as a medium of mined land reclamation. Expected by the Bio-Vegetation Method (Bioveg) may make it easier to overcome the failure of reclamation, to facilitate the mining in restoring ecological conditions, and minimize the environmental damage due to the impact of mining waste. FOR 030 Geospatial Approach Determining Anthropogenic Factors Contributed to Deforestation of Mangrove: A Case Study in Konawe Selatan, Southeast Sulawesi. Dewi Nurhayati Yusuf*, Lilik Budi Prasetyo, Cecep Kusmana, Machfud (Bogor Agricultural University; [email protected]) Human activities play an important role in the occurance of damage to the ecosystem, especially those located in cities with rapid developing areas. The coastal area is one that has a very high resource potential, but it also susceptible to damage since most of the population live in there. Mangrove is one of the dominant coastal ecosystem, highly productive, complex and high-value benefits, therefore it is important to learn how anthropogenic factors affect the level of disruption to the mangrove ecosystem. In this paper, several factors that are considered as dominant such as access to land, port activities, aquaculture activities, the status of mangrove forests, as well as the rate of population growth has been evaluated through a case study in Konawe Selatan coastal area, Southeast Sulawesi Province. Geospatial model approach was used to map the zone with the disturbance level is high, medium and low, based on the anthropogenic factors. The output of this study showing the areas with the highest disturbance level is around the Kolono Bay, sub-district Tinanggea, sub-district Palangga Selatan, sub-district Laeya and sub-district Lainea. It can be concluded that the model of mangrove ecosystem disruption level due to anthropogenic factors may be determined more closely to the factual situation involving socio- economic data. This study may provide a guide for future studies on mangrove susceptibility mapping as well as a reference in determining the strategy of sustainability mangrove management. Program Book 105

Prita Ayu Permatasari*, Yudi Setiawan, Rahmi Nur Khairiah (Center for Environmental Research; Bogor Agricultural University; [email protected]) Indonesia is an archipelago in the tropical climate that has the largest mangrove forest in the world. Based on data from the Ministry of Environment and Forestry, mangrove forest area is estimated about 9 million hectares in 2000. However, this amount is reduced drastically. Approximately, sixty percent of mangrove forest area in 2006, has been lost, damaged, and changed into ponds, plantation, agriculture area, and settlement. Indragiri Hilir is one of regency in Riau Province which has the high potential diversity of mangrove. Based on interpretation of Landsat 8 satellite imagery in June - July 2013, mangrove forest in Indragiri Hilir reached 100,211.23 hectares. The area of mangrove forest is estimated to decrease, due to land use and land cover change. Based on survey results in Sungai Asam Village, there were five dominant taxa in the vegetation, Avicenia marina, Rhizophora mucronata, Rhizopora apiculata, Sonneratia ovata, and Nypa fruticans. FOR 033 Spatial Model of Wildfires in Regional Scale of Sumatra, Indonesia. Yudi Setiawan*, Ardhi Yusuf, Lilik Budi Prasetyo (Center for Environmental Research; Bogor Agricultural University; [email protected]) Wildfires are one of the major causes of environmental disturbance in Sumatra. Spatial modeling of wildfire will assist the policy makers to understand the process and to take it into consideration when decisions are made. Moreover, the result can be used as data input to solve environmental problem resulted from wildfire, such as smoke disaster. In this study, we use remote sensing data sets in conjunction with topographic, vegetation, climate, socio-economic factors and others for determining the potential causes of wildfires in Sumatra, Indonesia. We modeled the wildfire in Sumatra by using logistic regression. The hotspot occurrence was considered as the response variable, whilst biophysical, socioeconomic and policy factors that explain the current spatial pattern in wildfires were assigned as explanatory variables. Furthermore, we predicted future wildfire process, and then it was validated with actual hotspot derived from MODIS TERRA satellite imagery 2015. FOR 034 Estimation of Net Ecosystem Exchange of Tropical Forest and Oil Palm Plantations in Jambi Using Remote Sensing.

The amount of CO2 absorbed and released by Program Book 106

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 vegetation can be determined using the value of the Net Ecosystem Exchange (NEE). The objective of this research is to estimate NEE in tropical forest and oil palm plantations. NEE is estimated using remote sensing generated vegetation index (NDVI), leaf area index (LAI), PAR, plant respiration and soil respiration. The first step in calculating NEE, is determining Gross Primary Productivity (GPP) and Net Primary Productivity (NPP). Palm oil has GPP value greater than forests, whereas forest NPP is greater than the forest. Palm oil has CO2 absorption capacity of about 20 tCO2/ha/year - 37 tCO2/ha/year and is greater than the forests that absorb CO2 around 26.5 tCO2/ha/year - 31 tCO2/ha/year. Although forest CO2 absorption capacity is smaller than palm oil, forests absorb CO2 more stable in the long term. FOR 035 Stand Density Measurement by Landsat 8 Using Forest Canopy Density. Rahmi Nur Khairiah*, Lilik Budi Prasetyo, Yudi Setiawan (Center for Environmental Research (PPLH); Bogor Agricultural University; [email protected]) Remote sensing technology is useful in providing complete, rapid, and accurate information, particularly in measuring, mapping, monitoring and modelling of the forest. The development of remote sensing technology enable the technology to be used as tool in monitoring stand density. Forest Canopy Density (FCD) is biophysical variables used in describing stand density. Muhammad (2014) suggests that FCD can provide estimation of changes in forest quality, including forest degradation. FCD describes the dynamic changes of the stands based on four indices, i.e.: Advanced Vegetation Index (AVI), Bare Soil Index (BI), Shadow Index or Scaled Shadow Index (SI, SSI) and Thermal Index (TI). The method is considered accurate and efficient in term of time and budget allocation, and has been widely implemented (Azizi et al. 2008; Hadi et al. 2004). Research by Biradar et al. (2005) show that FCD method is very helpful to distinguish forest and non- forest within certain threshold value. The purpose of this research is to build a prediction model stand density by using FCD in Cidanau Watersheed. FOR 036 Classification Model for Forest Fire Hotspot Occurrences Prediction Using ANFIS Algorithm. Arif Kurnia Wijayanto*, Octo Sani, Nadia Dwi Kartika, Yeni Herdiyeni (Center for Environmental Research, Bogor Agricultural University; [email protected]) This study proposed the application of data mining technique namely Adaptive Neuro-Fuzzy inference system (ANFIS) on forest fires hotspot data to develop classification models for hotspots occurrence in Central Kalimantan. Hotspot is a point that is indicated as the location of fires. In this study, hotspot distribution is categorized as true alarm and false alarm. ANFIS is a soft computing method in which a given input–output data set is expressed in a fuzzy inference system (FIS). The FIS implements a nonlinear mapping from its input space to the output space. The method of this study classified hotspots as target objects by correlating spatial attributes data using three folds in ANFIS algorithm to obtain the best model. The Program Book 107

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 best result obtained from the 3rd fold provided low error for training (error = 0.0093676) and also low error testing result (error = 0.0093676). Attribute of distance to road is the most determining factor that influences the probability of true and false alarm where the level of human activities in this attribute is higher. This classification model can be used to develop early warning system of forest fire. FOR-037 Quadcopter Applications for Wildlife Monitoring. Sumantri Radiansyah*, Mirza Dikari Kusrini, Lilik Budi Prasetyo (Postgraduate students, Tropical Biodiversity Conservation Studies Program, Graduate School of IPB; [email protected]) Recently, Unmanned Aerial Vehicle (UAV) or drone used as an instrument to collect data for wildlife research. This study aimed to test quadcopter application for wildlife monitoring. Flight experiment with a camera (≥ 12 MP) at flying height ranges from 50-200 m above ground level (agl), produce aerial photographs with an accuracy of 0,85 – 4,79 cm/pixel. The type and settings of camera, vibration damper system, flight altitude and punctuality of the shooting, affects aerial photo quality. Flying with hiding take off at least 300 m from the target, at a height of 50 - 100 m agl, flight speed of 5 - 7 m/sec on fine weather is recommended for wildlife monitoring. Quadcopter noise level at a distance of 5 m on targets is below 30 dB, which means it does not cause disturbance for wildlife. Quadcopter presence with a distance more than 30 m from White-bellied Sea Eagles and Proboscis Monkey did not cause negative response. Quadcopter application should pay attention to the behavior and characteristic of wildlife. FOR-038 Greenhouse Gas and Air Pollutant Emissions from Land and Forest Fire in Indonesia during 2015 based on Satellite Data. Andik Pribadi*, Gakuji Kurata (Department of Environmental Engineering, Kyoto University, Japan; Department of Civil and Environmental Engineering, Bogor Agricutural University, Indonesia; [email protected]) Land and forest fire still become a major problem in environmental management in Indonesia. In this study, we conducted quantitatively assessment of land and forest fire emissions in Indonesia during 2015. We applied methodology of emission inventory based on burned area, biomass density, combustion factor and emission factor for each land cover type using several satellite data such as MODIS burned area, Pantropical National Level Carbon Stock Dataset, as well as Vegetation Condition Index. The greenhouse gases emissions from land and forest fire in Indonesia during 2015 were 806,408 Gg CO2, 8002 Gg CH4, 96 Gg N2O, while pollutants emissions were 85,268 Gg CO, 1168 Gg NOx, 340 Gg SO2, 3093 Gg NMVOC, 1041 Gg NH3, 259 Gg BC, 1957 Gg OC, 4118 Gg PM2.5 and 5468 Gg PM10.

FOR-039 Usage of Geographical Information System (GIS) and Remote Sensing in Development of Urban Forest Type and Shape in South Tangerang City. Gumilar Adam, Rachmad Hermawan*, Lilik Budi Prasetyo (Department of Forest Resources Conservation and Ecotourism, Bogor Agricutural University, Indonesia; [email protected]) The development of the city can give an adverse effect, such as the increasing of air pollutant, the decreasing of amenity, the decreasing of biodiversity. One of the ways to overcome the adverse effect is developing urban forest. In order to the urban forest produce a maximal function, the urban forest type must be determined previously. Whereas the urban forest shape was identified based on shape and distribution of land. The aims of this study were to determine the appropriate type of the urban forest and to identify the shape of urban forest in South Tangerang City, by using GIS and remote sensing. The steps of the research consisted of data collection, map preparation for air temperature map, slope map, soil map, landcover map, and data analysis. Landsat 8 satellite imagery with path/row 122/06, and acquisition of 14th September 2014 was interpreted for landcover classification. Scoring based on air temperature, land slope, and soil type was used to determine priority of the urban forest location. Furthermore, landuse planning was considered to determine the appropriate urban forest type. FOR-040 Fotest Information Derived from UAV Images. I.N.S. Jaya*, F. Mulia, R.P. Silalahi, A.J. Kardika, I.M.H Wijaya, Kusnadi, S. Wahyuni, E. Septyawardani Faculty of Forestry, Bogor Agricutural University, Indonesia; [email protected]) During the last five-year period, the technology of DRONE (Dynamic Remotely Operated Navigation Equipment), also called unmanned aerial vehicle (UAV) has been progressively improved, followed by attachment of finer camera resolution with a comparable price. This technology had brought a new perspective in forest inventory and monitoring. This paper explores the use of the UAV images for deriving forestry information commonly used to support a sustainable forest management (SFM). The main data used are digital images acquired from UAV having spatial resolution of approximately 10 m. The derivation of information from the images were mainly performed by qualitative and quantitative approaches. The qualitative approach was mainly performed using visual interpretation, while the quantitative approaches were carried out using a statistical methods i.e.: 1) discriminant analysis, 2) multivariate analysis, and 3) accuracy assessment. This study noted that the stand variables measured on the UAV images, i.e., the percentage of canopy density, crown diameter and number of trees could be used for estimating standing stock and biomass content, as well as assessing site quality.

The study area extends from 115°–125° E to 2.5°–8° S. The datasets were consisted of monthly geostrophic currents, sea surface heights, sea surface temperatures, winds, and chlorophyll-a from 2008 – 2012. The results showed that eddies which found at Makassar Strait (MS) has the highest diameter and speed of 255.3 km and 21.4 cm/s respectively, while at the southern MW has 266.4 km and 15.6 cm/s, and at FS has 182.04 km and 11.4 cm/s. From a total of 51 eddies found, the majority of eddies type was anticyclonic. At MS and FS, eddies formed along the year, whereas at southern MW were found missing in West Season. Moreover, the chlorophyll-a at area which eddies always formed has higher concentration than the area which eddies never formed. Even though, the correlation between eddies and the upwelling downwelling phenomena was not significantly proved by sea surface temperatures value MAR 002 Combining Ocean Numerical Model and SAR Imagery to Investigate The Occurrence of Oil Pollution, A Case Study for The Java Sea.

MAR 003 Development of an Automated Processing System for Potential Fishing Zone Forecast. Romy Ardianto*, Agus Setiawan, Jejen Jenhar Hidayat, Abdul Rohman Zaky, Ari Murdimanto (Agency for Marine and Fisheries Reseacrh and Development; Ministry of Marine Affairs and Fisheries; Indonesia; [email protected]) The Institute of Marine Research and Observation (IMRO) - Ministry of Marine Affairs and Fisheries Republic of Indonesia (MMAF) has developed a potential fishing zone (PFZ) forecast using satellite data, called Peta Prakiraan Daerah Penangkapan Ikan (PPDPI). Since 2005, IMRO disseminates everyday PPDPI maps for fisheries marine ports and 3 days average for national areas. The accuracy in determining the PFZ and processing time of maps depend much on the experience of the operators creating them. This paper presents our research in developing an automated processing system for PPDPI in order to increase the accuracy and shorten processing time. PFZ are identified by combining MODIS sea surface temperature (SST) and chlorophyll-a (CHL) data in order to detect the presence of upwelling, thermal fronts and biological productivity enhancement, where the integration of these phenomena generally representing the PFZ. The whole process involves downloading data, geoprocessing and layouting maps are generated automatically by Python and ArcPy. The results showed that the automated processing system can be used to reduce the operator’s dependance on determining PFZ and speed up processing time. MAR 004 Delineation of Maritime Management Boundary between Surabaya, Gresik, and Bangkalan Using Spot 7. Khomsin (Geomatics Engineering ITS Surabaya; [email protected]) Recently, a lot of marine resource management in this area such as shipping lane, Suramadu Bridge, Tanjung Perak Port, Teluk Lamong Port and other ports in Gresik and Bangkalan. According to the Law No. 24/2014 about local government, the authority of marine resource management is the provincial government up to 12 nautical miles from baseline. District and city governments just to get sharing of marine managed by province up to 4 nautical miles from baselines. The baseline as referenced in this law is high water level (HWL). The problem is maps (topographic map and nautical chart) which is used in this area were not referenced by HWL. Therefore, in this paper, we used SPOT 7 imagery to determine HWL in this area. After that, boundary of marine resource management is determined by median line and equidistance methods. Median line is used to determine maritime boundary between opposite cities/districts (Surabaya - Gresik and Bangkalan) and equidistance is used to determine between adjacent cities/districts (Surabaya and Gresik). The results of this study indicate that Surabaya, Gresik and Bangkalan Program Book 111

MAR 006 Spatial and Temporal Variability of Sea Surface Temperature in Makassar Strait through Java Sea Based on Multisensor Satellite Data. Muhammad Syahdan*, Agus S. Atmadipoera, Setyo B. Susilo, Jonson Lumban-Gaol (Marine Science Department, Faculty of Fisheries and marine Sciences, Lambung Mangkurat University, Banjarbaru, Indonesia 70721; [email protected]) Sea surface temperature (SST) obtained by Aqua-MODIS satellite from 2002 to 2012 was analyzed to determine the spatial and temporal variability in the key region of small pelagic fisheries between Makassar Strait and Java Sea. The spatial structure by using Empirical Orthogonal Function (EOF) analysis showed that four largest mode describe amount 67% by total variance. The largest value in mode 1 was 52% with positive anomaly SSTs showed that the stronger eigen vector occurred in the eastern towards southern of Kalimantan Island, while the weaker in the southern towards western of Sulawesi Island. As for temporal variation showed that the annual oscilation was dominant in this area where maximum SSTs occured in the first transition monsoon (April), while the minimum in the southeast monsoon period (August). The influence of southeast monsoon formatted the minimum SSTs area in the southern of South Sulawesi that was generated by parallel wind-driven induced to the coast and the divergent current close to the coast. Also in this period, there was a cold tongue leaded to the west in the Java Sea which temperature increased gradually. Due to inter-annual variability, minimum SSTs occured before El Nino whereas the maximum occurred before La Nina event. Program Book 112

Eko Susilo*, Yuli Pancawati, Adi Wijaya, Komang Iwan Suniada (Institute for Marine Research and Observation; [email protected]) Plankton plays an important role in the small pelagic ecosystem by providing good feeding source for marine biota such us larvae, juvenile, and small pelagic fish. Bali Straits already well known as the most important small pelagic fisheries in Indonesia, especially sardinella fisheries (Sardinella lemuru). S. lemuru was categories as filtered feeder fish with plankton as a major food source. This study aims to illustrate how environmental variables can influence the plankton abundance in Bali Straits. Plankton sample and environmental variables (salinity, pH, nitrate, phosphate, chlorophyll-a, and silica) were collected in the purse seine fishing ground during 2013. The stepwise generalized additive models (GAMs) were used to know the respond of 3 major groups of plankton (diatoms, dinoflagellates, and crustaceans) to environmental variability. GAMs result showed the differences respond each group with deviance explained (DE) 43.5%, 39.0%, and 56.9% for diatoms, dinoflagellates, and crustacea, respectively. For diatoms, nitrate was able to explain the highest deviance (23.9%) followed by salinity and silica. Dinoflagellates have high respond with pH (DE = 23.6%) followed by silica and salinity. Whereas for crustaceans, salinity has the highest influence (DE = 30.1%) followed by pH, nitrate, and silica. Both phosphate and chlorophyll-a have less influence for all plankton groups.

Angga Dwinovantyo, Henry M. Manik*, Tri Prartono, Susilohadi (Department of Marine Science and Technology, Faculty of Fisheries and Marine Science, Bogor Agricultural University, Bogor, Indonesia; [email protected]) Measurements of suspended sediment concentration (SSC) is one of the parameters needed to determine the characteristics of sediment transport. However, the measurement of SSC nowadays still using conventional technique, so it has limitations especially in temporal resolution. With better technology, the measurement can uses hydroacoustic technology like Acoustic Doppler Current Profiler (ADCP). Hydroacoustic is a technology that uses sound waves to various purposes such as detecting underwater targets. ADCP measured the intensity of backscatter from sediment particles. The frequency of ADCP used in this study was 400 kHz. The samples was measured and collected from Lembeh Strait, North Sulawesi. The highest concentration of suspended sediment was measured to be 98.89 mg L-1 and the lowest was 45.20 mg L-1. In time series data showed that the tidal condition was affected the SSC. Our study also observed that loss of sound signal such as spherical spreading and sound absorption to get more accurate results. Simple linear regression analysis performed to obtain the estimates the SSC. The comparation result of estimation of SSC from ADCP measurements and SSC on water analysis in the laboratory were insignificantly different. Based on all analysis, ADCP have great resolution for use in measurement of SSC.

MAR 014 Determining Pollution Status of Two Coastal Waters in Western Java: A Comparison between North Part and South Part. Yusli Wardiatno*, Hefni Effendi, Majariana Krisanti, Ali Mashar, Yuyun Qonita, Sigid Hariyadi. (Bogor Agricultural University, Indonesia; [email protected]) Coastal waters in the north part (Tangerang waters) and south part (Palabuhanratu bay) of western Java have different characteristics of topography and oceanography. Thus, anthropogenic pollution loads that affect water quality of both regions are also different. Water quality monitoring was conducted in dry season in both regions, which is in April-May 2013 in Tangerang waters at 52 observation points and May 2016 in Palabuhanratu bay at 5 observation points. Tangerang coastal waters were divided into three zones based on its distance from mainland, where Zone I was closest waters to mainland and Zone III was furthest one. Based on pollution index (PI) assessment, it was known that Zone I and III of Tangerang waters was experiencing low to moderate waters pollution, while Zone II only experiencing low waters pollution. Unlike the Tangerang waters, Palabuhanratu bay waters was still in good condition since all the observed water quality parameters still met the required quality standards. In general, there were several water quality parameters in Tangerang waters which had exceeded the quality standard based on Kepmen LH 51 2004 Class III, i.eTSS, turbidity, orthophosphate, lead, phenols total, ammonia, sulfide, dissolved oxygen, and total coliform. The pollution in Tangerang coastal waters was mainly caused by the pollution loads which is coming from anthropogenic sources, like power plants, farms, and also industrial and residential activities around the area.

Emiyati*, Anneke K.S. Manoppo, Syarif Budhiman (Indonesian National Institute of Aeronautics and Space (LAPAN); [email protected]). Total Suspended Matter (TSM) are fine materials or soil particles floating in water column that remains suspended by current until deposited in area of weaker current. These matters originate from land, plants, animals or microorganism found on the continental shelf. Water column could be turbid due to TSM that reduces the depth of light penetration and causes low productivity in coastal water. TSM concentration can be extracted from satellite image from backward scattering of light from water column in visible region and near infra red, which physically can be obtained by using Landsat 8 OLI data. The objective of this study was to estimate TSM concentration using Landsat 8 OLI data in Lombok coastal, Indonesia by using empirical approach between ratio bands of subsurface reflectance from Landsat 8 OLI data. The result of this study was compared with field measurements for validation and the accuracy was tested using t-test and the efficiency of the empirical model was tested using statistical analysis. The result showed that the estimation of TSM concentrations in Lombok coastal is 4-17 mg/l. The statistical analysis showed that TSM model from Landsat 8 OLI data could describe TSM from field measurement with correlation 74.2% and RMSE value between TSM field and TSM model is 1.09.

Agus Saleh Atmadipoera*, Rina Zuraida, Indra Jaya, Tri Prartono, I Wayan Nurjaya, Asep Priatna (Department of Marine Science and Technology Faculty of Fisheries and Marine Sciences Bogor Agricultural University; [email protected]) Physical processes and dynamics of Makassar coastal upwelling during El Nino 2015 event in the Triangle seas of Java Sea-Makassar Strait-Flores Sea have been investigated from Aqua-Modis satellite data, MAJAFLOX cruise hydrographic data, and eddy-resolved ocean general circulation model of INDESO. It is shown that surface features of Makassar upwelling are seen clearly from satellite data with low sea surface temperature (SST) and high chlorophyll-a (Chl-a) in the southern tips of Makassar during the peak of southeast monsoon period (July-September), consistence with previous studies. However, our hydrographic data provided new evidence that vertical extent of upwelling at its center is revealed by outcroping of isotherm 25°C, isohaline 34.5 psu, and isopycnal of 23.5 from sub-surface of about 60 m depth to the sea surface. This upwelling event is associated with much higher chlorophyll-a, nutrient concentration, as well as fish larvae distribution. It is proposed that responsible forcing mechanism of Makassar upwelling can be quantified from the Ekman theory of upwelling, where fully developed southeasterly monsoonal winds over the region drive southwestward Ekman transport from surface to subsurface layer toward offshore. A deficit of surface water mass volume near coastal area is balanced by upwelled subsurface water. Furthermore, the presence of persistent southward Makassar Indonesian Throughflow Jets and southwestward flows from Selayar Strait intensifies spatial extent of surface features of upwelling. Model results showed that on inter- annual time-scale, upwelling intensity is strongest during El Nino 2015 event compared to previoues ENSO years between 2008-2015. MAR 027 Responses of Coastal Society to Shore Erosion in Sugihwaras Village, Jenu Sub- District, Tuban.

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 Physical changes of natural environment form characteristic and behavior of people. Both of them enable people to manage and organize the environment, so that it can adapt to the situation and conditions. This study was conducted to assess response of coastal communities to face the risk of shore erosion in Sugihwaras Village Jenu Sub-District of Tuban. The method used is descriptive qualitative. Data collection techniques is observation and in-depth interviews. The results showed that the response of coastal society to protect the shore, such as; building protective wall on the shoreline; assemblies wooden pegs parallel to the shoreline; and planting pine. In addition, the unique case obtained from this research is despite being close to the sea, village residents of Sugihwaras is no one else as fishermen. This is caused most of them prefer to cultivate shrimp ‘vannamei’ in shrimp pond, which has a greater revenue of opportunities than fishing. All responses of coastal society can be categorized into Posibilisme groups, it means that people no longer depend on nature, but they have been able to find opportunities in order to maintain the shape of beach and to utilize it. The phenomenon of physis posibilisme groups built by the Sugihwaras residents based on the because motive is awareness among the coastal society that the dangers of erosion which have eroded parts of the beach and have in order to motive as a strategy of prevention of development of the beach in order to reduce the marine forces cause shore erosion. MAR 028 Toward Establishing An Optimal Drone Latitude for Seagrass Observation. Indra Jaya*, Beginer Subhan (Bogor Agricultural University; [email protected]) The seagrass field is very important to monitor since it plays a crucial role in fisheries as a nursery ground of some economically and ecologically important fishes. However, seagrass field is difficult and challenging to map using satellite remote sensing due to the relatively small scale of the field and its patchiness. Attempt to use other observation platform such as underwater acoustics instrument also facing similar difficulties. With recent advancement of drone technology and its accessibility, the technology has found myriad field for application, including in ocean environment monitoring and assessment. In this paper, we had attempted to use drone technology to observe underwater vegetation, namely seagrass. One of the questions that need to be resolve is the optimal observation height of the drone that provided the clearest imagery. To address this question we have flew the drone over the seagrass field at various latitude, starting from the lowest latitude of 1 m above the sea surface and increase gradually 1 m up to 20 m, and then we change the increment to every 5 m up to 50 m. The drone has operational frequency of 2.400 GHz - 2,483 GHz and equipped with lens with field of view 94 degree, 20 mm (3 mm format equivalent) and effective sensor pixels of 12.4 m. To determine the best imagery of each of the latitude taken, we compared the drone imagery with ground check observation. Program Book 122

Hawis Madduppa*, Resha Mukti Renjani, Mujizat Kawaroe, Nurlita Putri Anggraini, Beginer Subhan, Indri Verawati, (Department of Marine Science and Technology Faculty of Fisheries and Marine Sciences Bogor Agricultural University; [email protected]) The blue swimming crab, Portunus pelagicus (Linnaeus 1758), inhabits coastal areas throughout the Indo-West Pacific region, and is one of high fisheries commodity with export value for Indonesia and global market demand increasing annually. However, there have been no publications concerning genetic diversity and population subdivisions of P. pelagicus in Indonesia, which is important for management and sustainable fisheries. This study aimed to determine genetic diversity distribution of blue swimming crab in three populations (Kendari, Bombana, and Pamandati), Southeast Sulawesi, and their spatial genetic connectivity between populations, as well as its implications for sustainable fishery. A total of 41 individuals was amplified using cytochrome oxidase I mitochondrial of locus and 600-700 basepairs. Analysis results showed that genetic relationship among populations was close, with a moderate genetic diversity (Hd) ranged from 0.4 to 0.6 and and nucleotide diversity (?) ranged from 0.07 to 0.18 in three populations. In addition, high spatial connectivity was observed between three populations in a distance of more than 60 kilometers and no significant differences in population structure among populations (FST = - 0.023; p-value = 0.764), with a percentage of variation was -2.34% and 102.34% for among population and within population, respectively. This study suggests that population in Southeast Sulawesi likely one unit stock, and could the basis of blue swimming crab biology data in Southeast Sulawesi. Preferably one management plan and action across the region thoroughly and simultaneously is effective for management and their sustainable conservation. MAR 030 Biological Response to the Indian Ocean Dipole (1997/98 & 2006/07) and Its Impact on Sardinella lemuru Production in Bali Strait. Jonson Lumban-Gaol*, Bonar P. Pasaribu, Takahiro Osawa, Robert R. Leben, Stefano Vignudelli (Department of Marine Science and Technology Faculty of Fisheries and Marine Sciences Bogor Agricultural University; [email protected]) This study is aimed at understanding the variability of satellite-derived chlorophyll- a (chl-a) concentration and assessing their impact on Sardinella lemuru production in Bali Strait (Indonesia). Changes in the physical environment associated with Indian Ocean Dipole (IOD) events affect the biological response in the eastern Indian Ocean (EIO) well known. However, such biological responses have not been adequately investigated, especially in terms of fish production. Chl-a concentrations data were from 1997 to 2007 derived from Sea-viewing Wide Field-of-View Sensor (SeaWiFS) and MODerate resolution Imaging Spectro- radiometer (MODIS). Monthly Sardinella lemuru production derived from reports Program Book 123

The 1997/98 and 2006/07 IOD positive event was associated with the highest of chl-a concentration of phytoplankton in the eastern Indian Ocean off Java. These biological responses were dependent on the strength and extent of southesterly winds anomalies and their impact on upwelling Ekman transport was the primary factor to increase in chl-a concentration during IOD positive events in the EIO. Generally, the chl-a concentration reaches the highest in September related to upwelling generated southeast monsoon in EIO, but in 1997/98 and 2006/07 IOD, the chl-a concentration was the highest until November. The relationship between chl-a concentration and Sardinella lemuru production is significantly positive can be attributed to the enhancement biological productivity during IOD. The Sardinella lemuru production increased more than 2 times in the period of IOD positive. MAR 031 Detection of Potential Fishing Zone for Pacific Saury (Cololabis saira) using Generalized Additive Model and Remotely Sensed Data. Achmad Fachruddin Syah*, Sei-Ichi Saitoh, Irene D. Alabia, Toru Hirawake (University of Trunojoyo Madura; [email protected]) To evaluate the effect of oceanographic condition on the formation potential fishing zone (PFZ) and to determine the PFZ for Pacific saury, fishing locations of Pacific saury from Defense Meteorological Satellite Program/Operating Linescan System and satellite-based oceanography data of sea surface temperature (SST), sea surface chlorophyll-a (SSC), sea surface height anomaly (SSHA) and eddy kinetic energy (EKE) were used. A 2-level slicing method were used to identify the bright region as actual fishing areas for OLS images collected during the peak fishing season of Pacific saury in the North Pacific. Significance of model terms, reduction in Akaike’s Information Criterion, and increase in cumulative deviance explained were used in model selection. The model selected was used to visualize the basin scale distribution of Pacific saury habitat. Predicted potential fishing zones showed a consistent with the fishing location. The results from GAM revealed that Pacific saury habitat selection was significant (P<0.001) influenced -3 by SST ranges from 13-18°C, SSC ranges from 0.5-1.8 mg.m , SSHA ranges from 5- 2 -2 17 cm and EKE ranges from 700-1200 cm s . However, among the set of oceanographic variables examined, SST explained the highest deviance and was indicated as the most significant variable in the geographic distribution of Pacific saury MAR 032 Tracking Skipjack Tuna Fishing Ground in West Banda Sea Relations with Sea Surface Temperature Parameters from Aqua MODIS Satellite.

We measured underway using continous measurements systems for gaining sea surface pCO2 value in June 2012, November 2012 and June 2015 during SITE (The South China Sea – Indonesian Seas Transport (Exchange) and Dynamics of Sunda and Karimata Straits) cruise. The value of sspCO2 during SITE cruise in those area ranged between ~ 400 – 600 µatm and we found that the seawater pCO2 of study area (along Sunda and Karimata Strait) is relative higher than the atmosphere (380.9 ± 4.4µatm). We found a shifting community of phytoplankton through the elevation of concentration CO2 in surface water (in terms of sspCO2) where phytoplankton taxon dominance shifted from diatoms and dinoflagellates to picophytoplankton community. The changes in phytoplankton community under effect of the elevated of CO2 concentration (in terms of ssPCO2) has connection with the concentration of nutrient at those area. These results are significant for understanding the roles of the environmental conditions especially under high partial pressure CO2 upon the phytoplankton variability. MAR 035 Upwelling Analysis in Southern Makassar Strait. Ferdy Gustian Utama*, Agus Saleh Atmadipoera, Mulia Purba, Evie Sudjono, Rina Zuraida (Bogor Agricultural University; [email protected]) Southeast monsoon wind on May until October 2015 in South of Makassar Strait region raises the phenomenon of upwelling .This study aim to calculate the upwelling phenomena by Ekman Transport calculation. Southeast monsoon winds from ECMWF database between May and October 2015 in South of Makassar Strait region generate the upwelling phenomenon. Wind speed data show southeasterly winds with mean speed of 6 m/s. Maximum wind speed is revealed between August-September. Consequently, Ekman transport is maximum during this period and directed southwestward. Thus upwelled water near the coastal area is created. Estimate of vertical transport volume of upwelling is about 0.004 3 –0.010 m /s in the center of upwelling region. Ekman layer depth estimate is about 60 m. MAR 036 Water Quality and Anguilid Eel (Anguilla bicolor bicolor, McClelland 1844) Fishery in Kungkai Baru River, Bengkulu Province. Ni Komang Suryati*, Siti Fauziyah, Ngudiantoro (Research Institute of Inland Fisheries Jalan Gub. H. Bestari No.08 Jakabaring, Palembang; [email protected]) Anguilid eel is one of the fish which contain high nutrient content. Because of strategic position, directly connect to Indian Ocean, Bengkulu province has a big potential of eel resources. Kungkai Baru is one of the river in Bengkulu which has that resources. This study aimed to assess the water quality and Anguillid eel fishery in Kungkai Baru River, Bengkulu Province. Fish were collected using hand line (without hook) and traps from the river on June-July 2016. Water Quality Index (WQI) data were analyses using storet index and classified based on US-EPA Program Book 126

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 (Environmental Protection Agency). The result showed that water quality in Kungkai Baru was good for fisheries. The maximum Anguillid eel production was 74.8 kg in marsh area and the minimum production was 1.4 kg in the canal. The total number of fisherman maximum 30 person mostly used traps (selective gears). MAR 037 Analysis of Turbulent Mixing in Dewakang Sill, South Makkasar Strait. Risko*, Agus Saleh Atmadipoera, Indra Jaya, Evie Sudjono, Rina Zuraida (Bogor Agricultural University; [email protected]) Upwelling is an important mechanism on productivity enhancement in the Southern Makassar Strait (MAK). Previous studies found a corellation between upwelling events and chlorophyll-a blooms, which is perhaps caused by nutrient regeneration from deep water. Through a multi-disciplinary study “MAJAFLOX Cruise” in August 2015, CTD casts and seawater samples have been collected from MAK. The present study aims to investigate relationship between physical processes of upwelling and nutrient usage, especially for nitrate, phosphate and silicate from regenerated processes to be used for the primary productivity (chlorophyll-a). The results show that upwelling center is found near Dewakang Sill around St. 4, associated with the highest chlorophyll-a concentration (0.438 µgL-1) especially in the sea surface. Relatively high nutrient is also revealed in other stations of observation. In sea surface layer, nitrate is high in St. 3, but phosphate and silicate is in St. 5 and 6. This shifting of high nutrient concentration may indicate spatial variation of biogeochemical processes in the surface layer associated with nutrient fluxes. MAR 038 Using Remote Sensing and GIS in Mapping Coastal Seafood Resiliency. Agustinus M Samosir*, H. Hadiana (Department of Aquatic Resources Management; Bogor Agricultural University; [email protected]) In the increasing impact of climate change to primary industry, the integration of food resilience into food security assessment and management has become important. Based on experience on the coastal ecosystem resiliency and literature review on food resiliency we develop model and map the seafood resiliency in coastal aquaculture area using remotely sensed data and GIS. Eighteen physical, biological and social indicators are identified and grouped into seven categories applied to a seafood resiliency index: landward expanding space, brackish water pond productivity, pond system self-regulation, seascape diversity, aquaculture species heterogeneity, seed supply and fish-farmer adaptation capacity. Absence of these indicators identifies points of intervention for managers and stakeholders to build resilience where there is vulnerability. The result show the homogeneity of species cultured in Indramayu, the lack of seascape diversity and low adaptation of the farmer could lead into seafood insecurity. Program Book 127

Rossi Hamzah (Remote Sensing Application Center, LAPAN; [email protected], rossi.hamzahlapan.go.id) Information of Potential Fishing Zone (PFZ) currently has operationally using automation data processing system. To produce daily information covering all Indonesian waters required multi-satellite input data. Terra/Aqua MODIS and Suomi NPP VIIRS has been used since 2014 in the automation of data processing PFZ information. Currently Terra/Aqua MODIS has decreased the quality of data, so it needs new input data. Himawari-8 is one solution that is currently possible to substitute Terra/Aqua MODIS. By performing the same processing stages to the Sea Surface Temperature data and compare the thermal front identification results between the Himawari-8 and Suomi NPP VIIRS, are expected to be used as new input data to produce PFZ information. MAR 040 Nutrient and Chlorophyll-a Distribution in Makassar Upwelling Region: from Majaflox Cruise 2015. Annisya Rosdiana*, Tri Prartono, Agus S. Atmadipoera, Rina Zuraida (Bogor Agricultural University; [email protected]) Upwelling is an important mechanism on productivity enhancement in the Southern Makassar Strait (MAK). Previous studies found a corellation between upwelling events and chlorophyll-a blooms, which is perhaps caused by nutrient regeneration from deep water. Through a multi-disciplinary study “MAJAFLOX Cruise” in August 2015, CTD casts and seawater samples have been collected from MAK. The present study aims to investigate relationship between physical processes of upwelling and nutrient usage, especially for nitrate, phosphate and silicate from regenerated processes to be used for the primary productivity (chlorophyll-a). The results show that upwelling center is found near Dewakang Sill -1 around St. 4, associated with the highest chlorophyll-a concentration (0.438 µgL ) especially in the sea surface. Relatively high nutrient is also revealed in other stations of observation. In sea surface layer, nitrate is high in St. 3, but phosphate and silicate is in St. 5 and 6. This shifting of high nutrient concentration may indicate spatial variation of biogeochemical processes in the surface layer associated with nutrient fluxes.

MAR 044 The Effect of Land Use Change on Water Quality: A Case Study in Ciliwung Watershed. Prita Ayu Permatasari*, Yudi Setiawan, Hefni Effendi, Rahmi Nur Khairiah (Center for Environmental Research, Bogor Agricultural University; [email protected]) Ciliwung is the biggest river in Jakarta.It is 119 km long with a catchment area of 2 476 km . It flows from Bogor Regency and crosses Bogor City, Depok City, and Jakarta before finally flowing into Java Sea through Jakarta Bay. The water quality in Ciliwung River has degraded. Many factors affect water quality. Understanding the relationship between land use and surface water quality is necessary for effective water management. It has been widely accepted that there is a close relationship between the land use type and water quality. This study aims to analyze the influence of various land use types on the water quality within the Ciliwung Watershed based on the water quality monitoring data and remote sensing data in 2010 and 2014. Water quality parameters exhibited significant variations between the urban-dominated and forest-dominated sites.

MAR 046 Vertical Distribution of Dissolved Oxygen, Dissolved Inorganic Nitrogen, and Chlorophyll-a in Sunda and Karimata Strait. Muhammad Zainuri, Sutrisno Anggoro, Ita Widowati, Iis Triyulianti*, Faisal Hamzah, Eko Susilo, Teguh Agustiadi, Mukti Trenggono (Department of Marine Science and Technology; Bogor Agricultural University; [email protected]) The distribution of dissolved oxygen has a correlation to the concentration of nutrient and chlorophyll as a party of biogeochemical functioning in Karimata and Sunda Strait. We measured and observed those parameters to analyses the relation of dissolved oxygen (DO), dissolved inorganic nitrogen (DIN) and chlorophyll-a concentration in the surface water microlayer as a formation of water mass which is indicating have an interaction along the water column with different processes in each water layer. We have 33 stations during SITE (The South China Sea – Indonesian Seas Transport (Exchange) and Dynamics of Sunda and Karimata Straits) cruise in June 2015 along Sunda and Karimata Strait. The concentration of dissolved oxygen in surface micro layer water ranged 1,236 to 4,167 mg/L, with an average of 3,886 mg/L. The average concentrations of DIN and chlorophyll-a were 0.0045 mg/L and 0,252 mg/L. We found the highest concentration of DIN in Sunda Strait station at the depth between 75 – 250 meter with the lowest concentration of chlorophyll-a and dissolved oxygen.

We suggested there was a nutrient supply at those layer (thermocline layer) and will significantly impact to the nutrient biogeochemical cycling. MAR 047 Coastal Upwelling in Southern Coast of Sumbawa Island, Indonesia. Qamal Taufikurahman, Rahmat Hidayat* (Bogor Agricultural University; [email protected]) Variations of sea surface temperture and chlorophyll-a and their relationship with coastal upwelling in southern coat of Sumbawa were analyzed. Circulation and water mass characteristics in this region is strongly influenced by the monsoonal winds. In this study we calculate the Ekman transport, Ekman pumping variations in order to explain physical process of upwelling as well as to assess their relationship with SST and chlorophyll-a. During JJA season, the highest value of Ekman transport (-0.72 m s ) moves the water mass towards Indian 2 -1 2 -1 Ocean while Ekman pumping (0.15x10-4 m s ) is associated with upwelling event. Impact of coastal upwelling is identified from cooling SST and high chlorophyll-a. -3 The lowest and the highest values of SST (26.58 °C) and chlorophyll-a (0.6 mg m ) were found to be influenced by seasonal cycle. Relationship between the decreasing of SST and the increasing of chlorophyll-a concentrations were found in JJA season (r=-0.83 and r =0.69). These imply that the decreasing of SST can be 2 explained linearly about 0.69 towards the increasing of chlorophyll-a concentrations and 0.31 could be explained by other factors, such as supply of nutrients (product of run-off from the mainland) and the mixing process of deep cold water through the coastline.

Yopi Ilhamsyah*, Yonny Koesmaryono, Rahmat Hidayat (Applied Climatology; Graduate School of Bogor Agricultural University, Bogor Indonesia 16680 and Syiah Kuala University, Banda Aceh Indonesia 23111; [email protected]) Long-term lightning activity in Indonesia is poorly studied. Many ground-based lightning detection (LD) of Agency for Meteorology, Climatology, and Geophysics’ (BMKG) are newly operated. The emergence of spaceborne-lightning observation under NASA-Tropical Rainfall Measuring Mission (TRMM) could address the problem. The research aims to detect lightning trend anomaly over Indonesia using Lightning Imaging Sensor (LIS) and its detection efficiency (DE) on local lightning detection system. Lightning data are retrieved from LIS, onboard optical sensor installed at NASA-TRMM satellite. The device captured lightning flashes (both Intra-cloud and cloud-to-ground) since January 1998-December 2013. Spatial resolutions of the data are 0.5 degree longitude x 0.5 latitude, cover the entire Indonesia between 12.5S-10.5 N and 90.5-140.5E. Meanwhile, temporal resolution is monthly lightning flashes. For validation, detection efficiency is carried out by comparing between flashes and lightning strokes retrieved from BMKG’s cloud-to-ground measurement over Bogor District in 2012. The results show that anomaly of annual trends of lightning flashes over the Malacca Strait, Greater Jakarta Areas (Jabodetabek), and Central Sulawesi have significantly increased from year to year. The Malacca Strait, equatorial-type climate, show that during El Niño 2002-2003 and 2009-2010, lightning was higher in the beginning of the event. On the contrary, over Jabodetabek and Central Sulawesi which are monsoonal-type climate, lightning was lower at first. It is interesting to investigate more details on the relationship between lightning flashes and El Niño event particularly in monsoonal-type climatic zone where El Niño’s impact is the strongest. DE showed a nearly-perfect validation (90%) between ground and space-based observation.

SAT-005 A Study of the Partial Acquisition Technique to Reduce the Amount of SAR Data. Rahmat Arief*, Dodi Sudiana (National Institute of Aeronautics and Space (LAPAN), Indonesia; [email protected]) Synthetic Aperture Radar (SAR) technology is a remote sensing system that is capable of providing image data and information with high resolution at a desired target object from a moving vehicle. There is a serious problem which the SAR signal is acquired using high rate analog digital converter causing large volumes of raw data. In this paper is studied a new approach to partial sampling technique to reduce the amount of SAR raw data using compressed sampling in both the azimuth and range. The simulation results showed that the reconstruction of SAR image using partial acquisition models has good resolution comparable to the conventional method (Range Doppler Algorithm/RDA). On a target of a ship, that represents a low level sparsity, a good reconstruction image could be achieved from a fewer number measurement (until 7.44% of the full raw data). Program Book 141

Agung Wahyudiono, Agus Herawan (National Institute of Aeronautics and Space (LAPAN), Indonesia; [email protected]) Today LAPAN has several experimental micro satellite that have been made by its engineer. As a microsatellite it has some limitation that sometimes need a special treatment to maintain or extend the satellite lifetime. It was become another problem when the number of satellite increased. Each satellite has it own characteristic differ by its mission. One of satellite has an equatorial orbit that will overpass the Indonesian region 14 times per day. And the other satellite has a polar orbit, and it need special treatment to prevent from suffering latch up since it passed the SAA. Another problem come from the limited time to contact the satellite so it's cannot cover all of Indonesia region from a single contact. It's need cooperation between LAPAN ground stations, by centralize command and monitoring from a command center in order to optimized the used of satellite. This cooperation model will use the internet line for data exchange. The internal VPN of LAPAN is one of alternatives to be used for this model. This paper will produce a model of modular ground station that hopefully easy to replicate and easy to implement if LAPAN want to add another operation ground station. Every module will be connected each other into one integrated ground station network.

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 In the synoptic scale, one of the important meteorological parameter is the atmospheric boundary layer. It used to view characteristic of the atmospheric boundary layer structure like turbulence and atmosphere stability. Research about boundary layer become crucial because most of the weather phenomena affected by interaction between atmosphere and surface layer at this layer. Weather Radar used as an instrument to measure meteorological parameter with high temporal resolution and wide coverage area. For the comparative, we use Weather Research and Forecsting – Advanced Research (WRF-ARW) model to calculate Turbulance Index 2 (TI2) and Richardson Number. Data taken during two days, to compare boundary layer thickness between cloudy sky and clear sky. Vertical wind profiles determine windshear to identify the top of ABL, spectral width, TI2, and Richardson Number used as a turbulance parameters. Windshear good enough when identify ABL thickness especially when the weather is clear, in addition spectral width has the best performance when some cloud occupying sky. But TI2 and Ri as turbulance parameter failed to determine the thickness of ABL on the bad weather or clear condition.

T h e 3 r d I n t e r n a t i o n a l S y m p o s i u m o n L I S A T 2 0 1 6 Barium Strontium Titanate (BST) is a promising material for sensor devices such as temperature and infrared sensor. BaxSr1-xTiO3 thin films with affordable Si substrate were prepared by chemical deposition methods and spin coating technique for 30 seconds with variation in rotation speed (3000 rpm, 5500 rpm 0 and 8000 rpm). A high baking temperature at 850 C has been used for 8 hours during the annealing process. The thickness of BST film was calculated via gravimetric calculation. USB 2000 VIS-NIR and USB LS-450 was used to characterize the optical properties of BST thin film. The obtained reflectance curve showed that the most reflected wavelengths were in the range of 408-452 nm respectively. The result of optical film characterization is very important for futher development as a temperature sensor on satellite technology. SAT-013 Hydrological Similarity Approach and Rainfall Satellite Utilization for Mini Hydro Power Dam Basic Design (Case Study on the Ungauged Catchment at West Borneo, Indonesia). Wahyu Gendam Prakoso*, Kukuh Murtilaksono, Suria Darma Tarigan (Graduate School, Bogor Agricultural University, Indonesia; [email protected]). An Approach on flow duration and flood design estimation on the ungauged catchment with no rainfall and discharge data availability was been being develop with hydrological modeling including rainfall run off model implemented with watershed characteristic dataset. Near real time Rainfall data from multi satellite platform e.g TRMM can be utilized for regionalization approach on the ungauged catchment. Watershed hydrologically similarity analysis was conducted including all of the major watershed in Borneo which was predicted to be hydrologically similar with the Nanga Raun watershed. Nanga Raun watershed is situated in the headwaters of Kapuas River. It was found that a satisfactory hydrological model calibration could be achieved using catchment weighted time series of TRMM daily rainfall data, performed on nearby catchment deemed to be sufficiently similar to Nanga Raun catchment in hydrological terms, with RMSE value respectively 4.257 %. Relatively reliable flow duration curve and extreme discharge value estimation were produced with reasonable several limitation e.g limited length of TRMM data, hydrological similarity analysis limited in the hydrological terms only that means do not covers whole of the rainfall run off physical process. Further approach may be performed with some novel approach like downscaling of global climate model.

SAT-017 Preliminary of Optical Lens Design for Micro-Satellite. Elvira Rachim*, Andi Mukhtar Tahir, Agus Herawan (National Institute of Aeronautics and Space (LAPAN), Indonesia; [email protected]). The development of micro satellites for the last two decades is emerging rapidly as the need of satellite communication usage is increasing. Earth observation is one of the example of how satellites are on demand. Most observation satellites consist of sensors and imaging system on-board. One of the key element to have a good imaging system is a special optical lens system design. Such lens is designed specifically by calculating every parameter such as refractive, reflective indexes, type of surface, distance and many more. Manufactured lenses sometimes do not match the requirement of an imager system hence the special lens design is needed. This paper will first briefly describe the history of optic, theory related to lens system, then the design and the analysis of lens system for micro-satellites generally and LAPAN A3 particularly.
