Kata Kunci: Dinding Penahan Tanah, Faktor Keamanan,Tanah Longsor ABSTRACT The area of East Kalimantan which has a tropical climate with high rainfall at the end of each year causes the possibility of landslides to occur so large. Based on landslide data from the National Disaster Management Agency (BNPB) in 2020 Until 2022, ± 3000 landslides have been recorded in Indonesia. In the case of landslides on the Trikora road, Samarinda Seberang District, East Kalimantan, it occurred ± 3 times. This landslide occurred because it was influenced by ± 200 mm rainfall and included moderate rainfall. The landslide caused all roads to be cut off. In this way, the government will take corrective actions, one of which is the construction of retaining walls/pipes with the aim of preventing further landslides. This study aims to determine the safety factor of the slope, and to test the strength of the soil itself and the retaining wall. The method used in determining the safety of the slope itself uses the Mohr-Coloumb method with the help of Plaxis or Slide software. The test this time was carried out on a laboratory scale using the Direct Shear Test tool. The results of the analysis that the slope safety factor value is 1.393 and if given a load of 100 KPa the slope safety factor value is 0.819. For the stability of the retaining wall, it is obtained that the stability against overturning is 1.79, the stability to shear is 0.91, and the stability to the bearing capacity of the soil is 3.44. The safety factor of the slope with a 3 meter pile drill is 2.459 and the safety factor of the slope with a 6 meter pile drill is 2.630. The calculation results obtained the value of the safety factor of the wall is safe against the slope.Keywords: Safety Factor, RetainingWall, Landslide

: Claystone is a rock that has a denser structure with more mineral composition than siltstone. In addition, claystone can also be interpreted as a type of sedimentary rock that is clay or plastic, composed of hydrous aluminum silica (a clay mineral) whose grain size is fine and the claystone is often easily destroyed in a short time when it is exposed to the surface and interacts with water. From the test results it can also be obtained a comparison of rock strength values between location 1 and location 2 by correlating the results of testing the physical properties and mechanical properties of each location where for location 1 has a natural water content value of 17.38% and a saturated water content of 24.39% with the cohesion value of claystone under natural conditions is 0.209 MPa, saturated conditions are 0.2105 MPa and dry conditions are 0.2517 MPa. Then for location 2 it has a natural water content value of 22.87% and a saturated water content of 32.84% with a claystone cohesion value of natural conditions of 0.0923MPa, saturated conditions of 0.0377MPa and dry conditions of 0.2099 MPa. It can be concluded that the claystone location 1 has a smaller water content presentation than the claystone location 2. It can be concluded that the water contained in the claystone greatly influences the strength of the claystone in resisting the forces received to experience a shift and also water affects the attractive force between claystone particles which makes the strength of the rock weak.
