The stability of the slope is related to the sliding, which is the process of moving the natural mass of the soil from a high place to a lower place. it is influenced by several factors, such as the distance of the ground water level, the slope angle, the shear strength value and the soil type of the constituent layer having different values of cohesion and friction angle. In this study, the groundwater level is varied with a depth of 2 meters, 4 meters, 6 meters, 8 meters, 10 meters, 12 meters, 14 meters, 16 meters, 18 meters, 20 meters. Secure value is obtained from the analysis of SLOPE / W gesoslope 2012 software. The results show that the smallest secure number is at a depth of 2 meters and the largest safe rate is at a depth of 20 meters. Thus, the deeper the groundwater level, the greater the value of the safety factor.
