The assessment method uses resistivity analysis with the Wenner configuration and geological analysis by observing rock outcrops on the slope. Resistivity rocks value the Abang Batudinding Village was prone to landslides because there were cavities with fairly weathered rocks, at depths of 2-3 meters. Terunyan Village the surface part was andesite rocks with high resistivity, and some consist of weathered rocks with rock at a depth of 3-3.5 meters. The slope-forming rock, on average of the Andesite Breccia, has a volume above 60% of weathering rocks or sedimentary rocks. Weathered Andesite breccias produce intensive cracks in the horizontal direction and are easily released. The analysis shows the research area has a very high risk of debris flow, especially when the intensity of rain is high where the soil water level increases, so that the pore water pressure increases too. The loose soil will be easier to release debris flow.
