<![CDATA[In some areas in Indonesia, especially in East Kalimantan on Jalan M. Roem, Bontang City, where the slope conditions in the area are quite steep, triggering landslides that cause landslides and damage to the pavement layer in the area, therefore it is necessary to plan the construction of retaining walls (Retaining Wall) to prevent landslides in the area. In this study, the analysis method uses Geo5 software making models that are in accordance with the existing conditions in the field and manual calculations using the Bishop method of slices with a circular landslide plane approach. The purpose of this study is to determine the effectiveness of designing cantilever retaining walls on slopes and obtain factor values (Safety Factor) from the results of slope stability analysis after being reinforced. The results of calculating the safe number value on slopes using cantilever retaining wall reinforcement using Geo5 software obtained a safe number value of SF Boling = 2.56, SF Shear = 2.61, SF Soil bearing capacity = 3.43, and SF Global = 2.23. Meanwhile, the results of the manual calculation analysis obtained were SF Overthrow = 2.48, SF Shear = 2.66, SF Soil Bearing Capacity = 3.03.]]>
