Abstract
Satui is a Tanah Bumbu sub-district that is in the territory of South Kalimantan yielding mainly coal. The illegal and uncontrolled coal mining formed a steep slope in this area. The slope was exactly shaped close to a telecommunication tower building and other buildings. The excavation in this area provoked an eroded and imbalanced slope thus triggering a landslide. This research is aimed to deal with erosion prevention and disaster risk reduction to mitigate the environmental impact. The investigations of slope and soil conditions are used to obtain soil data as the first stage of research. The second stage is analyzing the slope stability toward soil data. A stable slope condition is indicated by existing analysis with FoS 1.66. Yet to avoid future disaster risk, slope reinforcement by employing Geo-Anchor is performed. The last stage is executed by implementing the proposed drainage and slope surface formation.
