Analisis kebakaran lahan gambut menggunakan Citra Satelit Multitemporal

Abstract

Forest and land fire can be monitored using image data through hotspot observation. Hotspots are hot spots of the earth's surface, where they are indicative of forest and land fires. Forest fires are a recurring occurrence in Indonesia, especially on the islands of Sumatra and Kalimantan. The calculation of burned areas through terrestrial surveys requires a very long time and very high cost. Therefore, it is necessary to develop a method for the analysis of land fires (burned area analysis) using remote sensing satellite data in the form of Landsat 8 which has an advantage in accuracy, fast, consistent and inexpensive and can be done on a relatively wide area. The purpose of this research is to determine hotspot point using thermal channel of landsat 8 year 2015 and analyze peat land fire using satellite image of Landsat 8 in Banjar Regency. In this research the method used is Differenced Normalized Burn Ratio (DNBR) by entering Normalized Burn Ratio (NBR) value in April and September, after that is done to identify surface temperature to get hotspot point in image. Results from Differenced Normalized Burn Ratio (DNBR) obtained a map the area of burned. The result of this research is obtained by thermal image analysis of Landsat 8 as many as 177 hotspot spread almost in all peat land area and the severity of peatlands of Banjar Regency is divided into 4 severity levels namely low-severity burn area of 3,316,004 ha, modereate-low severity burn covering 966,146 ha, modereate-high severity burn area of 873,303 ha and high-severity burn area of 28.127 ha.
