Analisis Spasial Kondisi Ekosistem Terumbu Karang sebagai Dasar Penentuan Kawasan Konservasi Laut Dengan Metode Cell Based Modelling di Karang Lebar dan Karang Congkak Kepulauan Seribu, DKI Jakarta

Abstract

This research aims to identify potential sites for Marine Protected Area in Karang Lebar and Karang Congkak. Seribu Islands, utilizing Formosat satellite data, field survey, and spatial ul/u/nis lIsing cell-based modeling method. Parameters applied for effective design of MPA \I.:.'re ope of substrates, number of species and indil"iduals of reeffish, depth, also distance towards transportation patmvays and community residences. All of them were stored in raster format ofgeographic information system package. Spatial analyses for raster data using cell based modeling was based on its advantage in modeling areas include the V,laters ofthe basic substrate. the number ofspecies ofreeffish, reeffish abundance, depth, distance from the cruise lines, and the dis lance from Ihe location ofthe study. Of all the parameters that can then be spatial and raster-based spatial analisis. Spatial analysis in raster data is the foulldmion of Cell Bmed }",fodeling. Selection ofCell Based Modeling method based on the advantage of this method ill modeling ofmarine protected areas that is more representative because based spatial analysis on raster data High-resolution satelli!e dalO is 8 x 8 m increase the accu"acy of the results ofimage processing .. From the results ofspatial analysis is included in the category are suitable 10 serve as a marine conservation area, 118.30 hectares lot area located at the edge of the Coral Reef Width and Congkak. Region with hroad categories according to a lot of 789.02 hectares in the reef flat and the Coral Reef Congkak width, while the area lmsuilable for eXlhlll\'O/1 hus -!62.98 heclares.
