Analisis Potensi Kebakaran Lahan dan Upaya Pencegahannya dengan Berbasis GIS di Kecamatan Lintong Nihuta Kabupaten Humbang Hasundutan

Abstract

Land fires are events that are detrimental to many parties. Land fires on peatland are more dangerous and damaging compared to ordinary land fires. This is because fires in peatlands are very difficult to extinguish due to the embers that are below the surface. One of the regions with peatlands is in Humbang Hasundutan Regency in Lintong Nihuta District. The rainfall level in Lintong Nihuta District is in the medium rainfall category based on the BMKG category. Land use in Lintong Nihuta District is mostly dryland agriculture, plantations, settlements, rice fields, shrubs, and plantations. This study uses the overlay method and scoring of several types of maps, namely rainfall, soil type, and land use, to determine areas that are potentially experiencing land fires. The results of this study show that the level of land fire vulnerability in Lintong Nihuta District is divided into 4 categories, namely the low vulnerability category with an area of 5.53 percent, the moderate vulnerability category with an area of 37.62 percent, the high vulnerability category with an area of 55.05 percent, and the very high vulnerability category with an area of 1.81 percent. This scoring is based on the Module for Updating Mapping of Forest and Land Fire Hazards in South Sumatra Province in 2015. The results of the vulnerability scoring will be used as a reference for determining efforts to prevent land fires in Lintong Nihuta District.
