| Summary: | The district of Karang Sambung lies on interbedded calcareous sandstone and siltstone with an acceptable topography, leading to locals creating a small quarry. The excavation has been done traditionally at the quarry, which creating steep slopes on the quarry face that endanger workers. Therefore, stability analysis is necessary to ensure the safety of the quarry face. The quarry face was divided into two regions, and geological mapping and scanline mapping was carried out. The slopes were then analysed by empirical, kinematic, limit equilibrium, and finite element methods. Based on analyses, the slope has a high probability of wedge failure.
