Tingkat Kerawanan Kebakaran Gambut Di Kabupaten Musi Banyuasin, Sumatera Selatan (Peat Fire Susceptibility in Musi Banyuasin District, South Sumatra)

Abstract

Forest and land fire in 2015 was a catastrophe in Indonesia, as it did not only cause damage on forest ecosystem and environments, but also impacted human health and economic loss. This research aimed to identify hotspots distribution in 2014-2015 as an indicator of forest and land fire, and to analyze fire susceptibility in Musi Banyuasin district, South Sumatra. Data used for fire prone analysis consisted of land cover map, forest status, hotspots data derived from NOAA18, soil types, topography and moratorium map. Results showed that based on land function, hotspots were mostly found in production forest with hotspots density of 0.049 hotspots km-2. Based on land cover type, hotspots were mostly found in the open land (88 hotspots). Based on soil types, hotspots were mostly occurred on peat soils (180 hotspots and hotspot density 0.048 hotspot km-2). Soil type was mostly associated with hotspot occurrence. Sub-district of Bayung Lencir has the highest fire susceptibility among others. Low precipitation and El-Ninö phenomenon in 2015 were not the only drivers of peat fire. However two main current problems in the Forest Management Unit of Lalan Mangsang Mendis (e.g. illegal logging and open access) were driver factors of peat fire in the district
