Perubahan Tutupan Lahan Hutan Di Cagar Alam Rawa Danau Menggunakan Citra Landsat Dan Sistem Informasi Geografi

Rawa Danau Nature Reserve is an area of the old volcanic caldera located in Serang District, Banten Province about 100 km to the west of Jakarta. This area has been identified as a very important natural site on the island of Java. This is based on the fact that the main wetland ecosystem at Rawa Danau is the only remaining freshwater swamp forest ecosystem of peat swamp forests in Java Island. The objective of this study was to identify land cover classes and their changes in Rawa Danau Nature reserve area on 2006, 2011, and 2016, and also calculate degradation rate and reforestation during the time of observation. This study was conducted in April - June 2017. Data sources was generated from landat image ETM+7 coverage year of 2006 and 2011, Image Landsat OLI 8 coverage year 2016 and other supporting digital maps. Supporting tools and instruments used were software, ArcGis 10.1, Erdas 9.1, GPS, Camera and Stationary. The result showed that land cover can be successfully classified both digitally or visually and composed of secondary swamp forest, marsh bushes, fields, settlements, water body and swamp. Highest degradation during 2006-2016 occured on swamp forest that was converted into fields, while highest reforestation happened on fields that became swamp area

Perubahan Tutupan Lahan Hutan Di Wilayah Daerah Aliran Sungai Citarum Hulu Provinsi Jawa Barat Tahun 2009-2017 Menggunakan Citra Landsat Dan Sistem Informasi Geografis

Land use and land cover are important components in understanding the interaction of human activities with the environment. Forest management including planning and supervision in the Upper Citarum Watershed Area of West Java is very important to be done to prevent more severe forest degradation. The purpose of this study is to measure land use change from 2009, 2013 and 2017. This research method is to utilize remote sensing technology and geographic information system (GIS) and then compare 3 map of land cover change. The classification results show that the Citarum watershed area has 13 classes of land cover. The significant land cover change from 2009 to 2017 forest land cover decreased from 64,938.99 Ha to 43,268.00. The rice field land cover class is scattered throughout the upper Citarum watershed area. Bandung District, West Bandung District, Bandung City, Cimahi City, Sumedang District and a small part of Garu
