Zusammenfassung:Sawahlunto City is one of 19 cities/regencies in West Sumatra Province that is highly vulnerable to landslides. The topography is steeply wavy, including in Kubang Tangah village, Lembah Segar subdistrict. The city already has a land use plan that limits urban development. During the Dutch East Indies government, Sawalunto was known as a coal mining city. This city did not develop for a time after coal mining stopped. Studies that provide scientific considerations are needed, considering that this city has limited land, is prone to landslides, and is an underground mining area. As such, geological studies and geotechnical investigations are carried out to obtain the necessary data, followed by an analysis of the potential for landslides in the Kubang Tangah village area, which, in April 2023, experienced a landslide disaster resulting in road infrastructure and several houses being damaged. Furthermore, based on the analysis of safety factor criteria using the limit equilibrium method, which compares driving forces and slope-resisting forces, it is proposed to be considered in plans to develop settlements and road infrastructure to reduce the risk of landslides.
