Abstract

Tepian Langsat Village, located in Bengalon District, East Kutai Regency, East Kalimantan Province, is classified as a landslide-prone area. Rural development has significantly altered topographic and morphological characteristics due to activities such as plantations, agriculture, mining, residential expansion, and ecotourism. This community service project aims to address the landslide risk in the area through geological mapping and hazard analysis. The methodology involves literature review, geological and topographic mapping to collect data on lithology, soil types, slope gradients, land use, and landslide hazard zones. The results indicate that the dominant lithologies are sandstone and claystone, which serve as potential slip surfaces. Land use is dominated by oil palm plantations, agriculture, mining, and protected forest areas. Slope classification ranges from flat to very steep (0°–45°), and the landslide hazard is categorized into five levels: very low, low, moderate, high, and very high. In addition, training sessions were conducted to empower local residents in utilizing Geographic Information Systems (GIS) for hazard monitoring and disaster mitigation. This initiative contributes to community-based disaster risk management and supports sustainable land use planning.
