Kajian Perubahan Penggunaan Lahan Tahun 2000-2015 Sub Das Sail Menggunakan Data Citra Satelit

Abstract

Land cover changes were one of the variables that can affect the watershed system. Land cover changes were in the form of anthropogenic activities. The aim of this research was to identify land cover changes in Sail Sub Watershed using remote sensing data. The data that were used are Landsat 5 TM Imagery year of 2000, 2005 and 2015. The data has been digitized using GIS techniques by on screen digitization. The results showed remote sensing data quite accurate to land cover or land use information extraction with 88% accuration. Land cover in Sub DAS Sail has been classified by using local knowledge. The results shown that land cover in Sub DAS Sail can divided into 6 (six) classes such us built up land, bush, swamp area, agriculture, oil palm plantation and water body. From 2000-2015 built up land area and oil palm plantation has increasing pattern, meanwhile bush and swamp area were decreasing over the year. This condition surely can impact the watershed condition like hydrological conditions. This information will be useful for the watershed management, especially in floods case and the general for regional planning.
