Abstract
Indonesia is a country that has a fairly high intensity of natural disasters including landslides, tsunamis, earthquakes, volcanic eruptions, floods, tornadoes, and forest fires. One of the areas in Indonesia that is in danger and vulnerable to landslide is Lebak Regency. Seven sub-districts are the center of the flood and landslide crisis in Lebak Regency, including Banjarsari, Bojongmanik, Gunung Kencana, Leuwi Damar, Kalang Anyar, Cimarga, Muncang sub-districts on 03-01-2023 (Crisis Center of the Ministry of Health of the Republic of Indonesia, 2023). The purpose of this study was to obtain a map of the physical hazards and vulnerability index of landslides using the overlay method of the Geographic Information System (GIS). The parameters used include height, slope, rock type, soil type, potential for land movement, village boundaries, and physical points. The level of danger is divided into 3 classes, namely high, medium, and low. The results of this study obtained a landslide hazard index map (Figure 5.8) and the physical vulnerability of landslides (Figure 5.12) in Banjarsari District, Lebak Regency. Based on the physical aspects of Banjarsari District, Lebak Regency with a total of 12,724 points that have the highest level of vulnerability including: in the low category, namely settlements/houses with a total of 3887 points or 97% of 4,007 points, the medium category in settlements/houses with a total of 7,781 points or 95% of 8,139 points, and in the high category, namely settlements/houses with a total of 558 points or 96% of 578 points..
