| Abstrak According to the Regional Disaster Management Agency (BPBD) (2020) in Rajawalipost, (2020) in Poso Regency, the landslide disaster that occurred in 2020 in Poso Pesisir Selatan brought materials in the form of mud and wood that caused a buildup on the Watumaeta-Sangginora road section, resulting in cutting off transportation routes and impacting people who wanted to travel to Poso City. Based on this problem, research is needed to analyze the level of landslide vulnerability using a geographic information system (GIS) with scoring and overlay techniques on parameters such as rainfall, slope gradient, soil type, land elevation, land cover. The results of this study will be in the form of a landslide vulnerability map. This research covers the entire area of ??Poso Pesisir Selatan District, Poso Regency, Central Sulawesi, with an area of ??587.59 km². This research was conducted over a two-month period, based on data collection in the field and at relevant agencies, from October 2023 to December 2023. Based on the results of the landslide vulnerability analysis using a geographic information system (GIS) conducted in Poso Pesisir Selatan District, Poso Regency, four landslide vulnerability levels were identified: low vulnerability with a value of 2.29-2.39 covering an area of ??564.42 hectares; medium vulnerability with a value of 2.50-3.10 covering an area of ??21,497.94 hectares; high vulnerability with a value of 3.19-3.79 covering an area of ??36,630.72 hectares; and very high vulnerability with a value of 3.90-4.20 covering an area of ??66.1 hectares. Of these four landslide vulnerability classes, the high class dominates, while the very high class has the lowest landslide vulnerability. |
