Abstract

Java Island is an area with hydrological disasters, especially landslides, which are classified as frequent. The landslide occurred because Java, especially West Java, has an extensive watery area of the entire region and has a high rainfall intensity. Geographical conditions that are dominated by basins in the form of ravines and cliffs make this area prone to hydrological disasters in the form of landslides. One of the areas prone to the hydrological disaster is the Cileunyi Sumedang - Dawuan (Cisumdawu) Toll Road Section. The purpose of this study is to examine the danger of landslides on the main road in Cileunyi section 1 phase 3 at STA 0 + 975 in order to determine the right solution in securing roads from hydrological disasters. The stages of the study began with the collection of primary data through soil investigations and documentation of existing conditions. Secondary data such as rainfall data, topographic maps, contour maps, maps of satellite images, and maps of rainfall posts were collected from related institutions. Data processing in the form of geotechnical analysis to determine slope stability, hydrological calculations to determine the planned rain flow, and groundwater level calculations using the tank model method. Slope stability analysis calculated using plaxis software shows that the slope has a displacement, and the safety rate is less than the requirement. So that a strengthening/protection is needed to maintain the stability of the groundwater level while reducing the risk of landslides in the project area.
