Boundary equilibrium method is one of the methods applied in numerical analysis in the geotechnical field. Slope stability is determined by the values of safety factors. This is obtained from various methods, i.e. discussing the usual method or Fellenius method, Bishop method, Bishop Simple method, Simple Janbu Method, Spencer Method, and General Limit Equilibrium method, GLE / Morgenstern-Price method. Pore water pressure, soil shear strength, and slope geometry are factors that can affect slope stability. The slope stability analysis was carried out on the slope by multi-level gravity walls. The research location is at the natural slope in Tupa Village, North Bulango, Bone Bolango District. The natural slope had collapsed (FS<1.0). After reinforcing the slope with a multi-level gravity walls, the slope became stable. The safety against sliding, FSs = 1.65 > 1.5, the safety against the overturning, FSo = 3.06 > 2.0, the safety against the bearing capacity failure, FS = 6.48 > 3.0, and the safety factor for global slope (using GLE/Morgenstern-Price method), FS = 1.64 > 1.5. The results of the study show how to increase slope stability increases with increasing shear strength. However, more pore pressure can cause a significant decrease in safety factors. Furthermore, increasing the load on the slope can also reduce the value of the safety factor. Keywords—Limit Equilibrium Methods, Slope Stability, Safety Factors
