Abstract
Cibodas Village is located in Palabuhanraty Bay, Sukabumi Regency. It is a highland and sloped area with a high risk of landslides. In the event of a natural disaster, the way the land is used, especially if people live in places that are prone to landslides, can be a major threat to the community. The purpose of this study was to figure out where people will live in Cibodas Village in 2021 and look at how the RTRW of Sukabumi Regency can be used in areas that are prone to landslides. In this study, a GIS-based multicriteria analysis is used to look at a lot of different factors. These factors include physical factors like rainfall, slope, and soil type, as well as landslide-prone areas and urban planning based on field survey data. Based on the results of this study, most settlements in Cibodas Village are found in areas with slope categories of 22.4 and 21.3 hectares, respectively. There is a risk of landslides in Cibodas Village, which has 3.14 hectares of suitable land and 53.91 hectares of unsuitable land. Landslide-prone areas vs. areas good for urban development gave a final result of 2.5 hectares as a priority and 60.5 hectares as a non-priority.
