KUD Sinamar Sakato is a company in the mining sector with an open-pit mining method. The actual geometry of the slope in the mining area is 25 m with a slope of 75º, and the actual FK value in saturated conditions is 1.038. The test data on the physical and mechanical properties of soil obtained a bulk density value of 14.22 kN/m3, a dry bulk density value of 10.16 kN/m3, a saturated bulk density value of 16.84 kN/m3, cohesion (c) = 49.533 kN/m2, and shear strength (ϕ) = 26.944º. This research uses the Bishop Simplified Method in its solution. The solution carried out to solve the slope stability is to make the slope into two slopes with each height of 12.5 m. FK saturated on each slope is 1.717, and FK overall slope saturated is obtained by 1.301. So, it can be concluded that the bishop method can be declared safe after the redesign. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
