Abstract

The vulnerability of landslides that occur in the Sakuli area, Kolaka Regency is related to topographic conditions which are dominated by mountains and hills, for this reason, research is needed as an effort to determine the level of vulnerability and determine disaster mitigation efforts against the danger of landslides. This type of research is quantitative descriptive by looking at the influence of each variable to analyze landslide-prone areas. The method used in this research is experimental analysis with direct observation in the field. From the research results, the vulnerability level value for the slope parameter was 0.83; with soil texture 0.408; for faults 0.86; value for regolith 0.363; with geological conditions 0.628; with a rainfall value of 0.3 and land use of 0.6, the accumulated value is that the research area is at a very vulnerable level with a value of 3.989. Therefore, this area really needs structural and non-structural mitigation to be able to protect and reduce the potential for landslides.

Abstract

The research location is located in Induha Village, Latambaga District, Kolaka Regency, Southeast Sulawesi Province. This study aims to determine the factors controlling landslides, and the types of landslides in the study area. The method used in this research is direct observation in the form of data collection and data collection that is found directly in the field including geological observations, taking rock samples, measuring slopes, and taking documentation of 3 points of landslides. Factors that control the occurrence of landslides in the study area are influenced by controlling factors, namely very steep slopes with a slope of around ± 62o – 67o. Lithological conditions are metamorphic rocks that have undergone changes due to pressure and temperature.
