DERIVING INHERENT OPTICAL PROPERTIES FROM MERIS IMAGERY AND IN SITU MEASUREMENT USING QUASI-ANALYTICAL ALGORITHM

The  paper  describes inherent optical properties  (IOP)  of  the  Berau  coastal  waters  derived from in  situ measurements  and Medium  Resolution  Imaging  Spectrometer  (MERIS) satellite  data. Field  measurements  of optical  water,  total  suspended  matter  (TSM), and  chlorophyll-a  (Chl-a) concentrations were carried out during the dry season of 2007. During this periode, only four MERISdata were  coincided with in  situ measurements on 31 August  2007. The MERIS  top-of-atmosphere radiances were atmospherically corrected using the MODTRAN radiative transfer model. The in situ optical  measurement  have  been  processed  into apparent optical properties  (AOP) and sub  surface irradiance. The remote sensing reflectance of in situ measurement as well as MERIS data were inverted into  the  IOP  using quasi-analytical algorithm  (QAA).  The  result  indicated  that coefficient  of determination (R 2) of backscattering coefficients of suspended particles (bbp) increased with increasing wavelength,  however  the  R2 of  absorption  spectra  of  phytoplankton  (aph)  decreased  with  increasing wavelength

GEOGRAPHIC INFORMATION SYSTEM AND ANALYTICAL HIERARCHY PROCESS FOR LAND USE PLANNING OF BEEKEEPING IN FOREST MARGIN OF BOGOR REGENCY, INDONESIA

One way to establish forest conservation is by improving the welfare of the community residing at the forests’ borders. Beekeeping has the potential to increase the income of the people around the forest. This study aims to delineate beekeeping zones bordering the forest regions. Multi-criteria analysis based geographic information system was used to delineate the ecologically suitable areas for honey bees. The parameters used included physical parameters (temperature, rainfall, distance from water source and altitude), economic parameters (distance from the roads and distance from the market) and social parameters (land use and distance from settlements). The parameters were weighed by applying analytical hierarchy process. The result was then inputted into a spatial model designed to determine the ecological suitability for honeybees. The suitable land for bees’ forages was delineated using land suitability analysis with maximum limitation method. The results of both analyses were then overlaid to delineate suitable areas for beekeeping. The analysis resulted in locating recommended areas for the cultivation of honey bees and forages around the forest periphery, by taken into account official spatial land use planning.Key words: Habitat suitability, land suitability, bee forage, land use plannin

Spatial Multi-criteria Decision Making for Delineating Agricultural Land in Jakarta Metropolitan Area\u27s Hinterland: Case Study of Bogor Regency, West Java

The hinterland of Jakarta has experienced high pressure in its land utilization due to Jakarta\u27s rapid development. The objective of this research was to analyse the suitable land available for agriculture. The research was conducted in Bogor, a hinterland regency of Jakarta. The methodology used includes two steps of analysis, which are land suitability and land availability analysis. Land suitability for agriculture was analysed using multi-criteria decision making method. Seven (7) criteria were included, which consist of soil class, land capability class, slope, elevation, slope aspect, land use/land cover and distance to roads. The criteria were weighted using the Analytical Hierarchy Process. Combining criteria weights and sub-criteria scores, an overlay model in Geographic Information System was applied. The result from land suitability analysis was used as a feed for determining land availability, considering the forest area status and land allocation in the official spatial land use plan. The results indicate that an area amounting to 87.5% of Bogor Regency is suitable for agriculture. Land which is suitable and available for agriculture is 16.7% of the regency\u27s area. Considering available land which is currently in use, the area that can be allocated for the expansion of agriculture is 3.3%

Existing paddy Ḁeld was delineated using high-resolution data from IKONOS imagery of 2012. Land use and land cover outside existing paddy Ḁeld were interpreted using SPOT-5 imagery of 2012. ἀe Automated Land Evaluation System (ALES) was used for land suitability analysis for paddy. ἀe results are interpreted in terms of the potential of paddy Ḁeld intensiḀcation in existing paddy Ḁeld area and the potential of extensiḀcation in land potentially used for paddy Ḁeld. ἀe result of analysis showed that in West Lombok Regency, there are still possible to do intensiḀcation and extensiḀca-tion of paddy Ḁeld to increase rice production in order to improve regional food security

EVALUASI LAHAN FISIK DAN EKONOMI KOMODITAS PERTANIAN UTAMA TRANSMIGRAN DI LAHAN MARJINAL KERING MASAM RANTAU PANDAN SP-4, PROVINSI JAMBI

Most of the land used for transmigration resettlement activities outside of Java Island is marginal land that requires highproduction inputs and susceptible to degradation. One of the need to be taken into consideration in the choice of location is land suitability. The objective of this study is to determine the land suitability of agricultural transmigration area with a case study of Transmigration Settlement Unit (UPT) of RantauPandan SP-4, Jambi Province, for cultivation of food crops, vegetables and perennial crops and analyse the level of biophysical and economical feasibility of several commodities. The actual land suitability assessment for the three agricultural commodities indicate the dominance land suitability classes of S3 (marginally suitable) with terrain, nutrient retention and nutrients available become dominant limiting factors. Economic land suitability analysis indicate that the biggest gross margin is rubber, while the smallest is rice. Results of analysis are used to determine the spatial land use recommendations on transmigration location. Results of analysis are not always in line with the transmigration pattern of land allocation. Nonetheless, these results suggested to be applied, for considerations of land conservation as well as farmers' welfare.Keywords: land suitability, automated land evaluation system, land quality, land characteristi

Land Use Planning for Brackish Water Shrimp Ponds in The North Coast of Tuban, Indonesia

Shrimp is a commodity that is increasingly in demand. The limited land resources implies the need of effective land use planning. The objective of this study was to assess land suitability for brackish water shrimp ponds, which then will be recommended for pond development in the north coast of Tuban, Indonesia. Analytical hierarchy process (AHP) were used to obtain the weight of the different criteria consisted of soil characteristics, topographic, water quality, and infrastructure criteria. The suitable land for brackish water shrimp ponds was determined by weighted overlay in GIS. The results show that the study area contains highly suitable land for brackish water shrimp ponds. Land use and land cover map was interpreted from 2014 SPOT 5 imagery.
