The Jeneberang watershed area is known for being susceptible to landslides. A field survey conducted in the Jeneberang watershed basin revealed that the slopes of andesite rock inclined up to 66°. Additionally, the rocks forming the slopes were found to be jointed. It is necessary to analyze slope stability and potential landslides at the study site. Some of the required data for this study include geological conditions, slope geometry, physical and mechanical properties of the rock from laboratory tests, and previous research findings. Slope modeling was conducted using Bishop’s limit equilibrium method in the Slide software to determine the Safety Factor (FS) value. Additionally, the Dips software was used to perform kinematic analysis and identify the type of landslides via stereographic projections. The slope is made up of andesitic and igneous rocks based on the analysis. The kinematic analysis of the stereographic projection results suggests that landslides on the research slope will occur in the direction of N 302° E. The type of slide that can occur on the slope is a plane (planar) type of slide. The safety factor of 4.1 indicates slope stability at the site, with little chance of sliding.
