| Abstract | Enrekang Regency is one of the districts in South Sulawesi that often happens landslide. Therefore it is necessary to mapping and zonation areas prone to landslides. This study aims to map and determine the risk level of landslides hazard in Enrekang Regency. Zonation level of landslides hazard risk is carried out by overlay technique of: landform map, gradien slope map, geology map, soil texture map, land use map and landslides hazard map, respectively. The landscape, gradien of slope, type of rock, soil texture and land use make in five class respectively, with the value 1 until 5. The landslides risk level is performed by overlay using ArcGis 10.3.The result of analysis shows there are 3 classes of landslides risk level in Enrekang Regency that is low, medium and high, respectively. There are sequences of areas most vulnerable to landslides, there are Bungin, Buntu Batu, Anggeraja, Enrekang, Masalle, Baraka, Baroko, Alla, and Maiwa. |
