<![CDATA[Slope failure is a geotechnical problem that can threaten the safety and functionality of road infrastructure, particularly in areas with steep terrain and high rainfall intensity. This study aims to identify the factors contributing to slope failure and evaluate the stability of the existing slope at STA 188+200 of the Muara Enim City Boundary–Sp. Sugih Waras road section, South Sumatra. The analysis was conducted using the Limit Equilibrium Method (LEM) with GeoStudio SLOPE/W 2025. The analysis incorporated slope geometry, soil unit weight, cohesion, internal friction angle, groundwater conditions, and pore-water pressure. Two analytical approaches, namely the Bishop Simplified and Morgenstern–Price methods, were used to determine the factor of safety (FoS) of the existing slope. The soil investigation indicated the presence of sandy clay, silty clay, sandy gravel, and clay layers with varying physical and mechanical properties. The analysis results showed that the existing slope has a FoS of 1.061 using the Bishop Simplified method and 1.068 using the Morgenstern–Price method. Both values are below the minimum FoS criterion of 1.50, indicating that the slope is in a critical and potentially unstable condition. The slope failure is influenced by a combination of geotechnical and environmental factors, including soil characteristics, slope geometry, groundwater conditions, and increased soil saturation due to water infiltration. Based on the analysis results, slope stabilization measures are required, which may include slope geometry modification, retaining structures, bored piles, or other appropriate reinforcement methods.]]>
