## Abstract
Jeneberang watershed has an important role in maintaining environmental stability, especially for the surrounding area. In 2004 a landslide occurred in the Jeneberang watershed which caused casualties and material losses. This study aims to determine the distribution and level of vulnerability to landslides in the Jeneberang watershed and to formulate an effective scenario to reduce the level of vulnerability. This research is located the Jeneberang watershed, South Sulawesi Province. The data used include data on the weight of each parameter and criteria for determining landslide susceptibility obtained from expert interviews, land use maps obtained from analysis of Landsat 8 OLI satellite imagery in 2020, slope maps, rainfall maps, forest area status maps, and map type. soil. The method used is the integration of AHP and MCE for landslide hazard assessment, GIS analysis and spatial decision-making for scenario simulation. The results of the analysis show that the rainfall parameter has the highest weight in determining the level of landslide susceptibility with a value of 0.327, the results of the MCE analysis for assessing the level of landslide susceptibility in the Jeneberang watershed show an area of 18.829 ha. or 18% of the Jeneberang watershed area which is classified as high hazard. The results of the analysis show that the use of an effective scenario reduces the landslide hazard at a high level of hazard. In the optimistic scenario, it can reduce the high vulnerability level by 9.14%, while in the moderate scenario it is effective in reducing the high vulnerability level by 8.72%.
