Tepus-Jerukwudel Road construction is one of the South Coast Java Road sections located in Gunungkidul Regency, Special Region of Yogyakarta. One of the hills with the deepest excavation depth is at STA 14+350. The research location includes the Punung Formation which is dominated by reef limestones. The existing rock lithology is floatstone. The depth of the road excavation is more than 20 meters. The slope design is 3V:1H. This research aimed to analyze the slope stability of the Tepus-Jerukwudel Road and assess the safety factor of the slope design. We used the finite element method (FEM) in the Rocscience Phase2 v8.0 software by applying the Generalized Hoek-Brown method for the rock failure criteria. The loads considered in the slope stability analysis were live loads, dead loads, surcharge loads, and seismic loads. The results of the slope analysis without seismic loads resulted in the safety factor values for the left and right slopes of 4,49 and 3,32, respectively. For seismic loads conditions, the safety factor values for the left and right slopes are 3,74 and 2,66. The results indicated that slope design of the road is in a stable condition in accordance with the estimated static and seismic loads.
