ANALISIS SPASIAL DALAM REKONTRUKSI LAHAN UNTUK EKOSISTEM MANGROVE MELALUI PERANCANGAN MODEL SPASIAL DINAMIS

Sari

The area of mangrove forests in DKI Jakarta has continued to decline from 1,140.33 hectares in 1960 to 308,70 hectares in 2015, from the decreasing area of mangrove forests. So, mangrove forest land must be planned so that the physical condition of the coastal area is maintained, this study was conducted on 4 (four) rivers in North Jakarta, namely: Cengkareng Drain, Banjir Kanal Barat, Cakung Drain and Banjir Kanal Timur with the purpose of research: describe land area formed in the river estuary from the sedimentation process until 2033. The method used in this study is a quantative method using analytical techniques: (1) Bad Load uses the Arcker's and White approach in completing the calculation of sediment transport, (2) using the Regression formula Linear in completing sediment transport projections until 2033 and (3) spatial analysis carried out using ArcGIS 10.1 software. The results of spatial analysis research in land reconstruction for mangrove ecosystems through the design of dynamic spatial models show that the area of land formed in 2033 was 51.80 ha (during normal sea water conditions) and 81.55 ha (during low tide conditions 30 cm).
