Abstract

The construction of Jalur Jalan Lintas Selatan (JJLS) infrastructure is implied to facilitate access and increase the potential for agriculture and tourism in the South Coast Region of Java. Slope stability evaluation should be done in this development infrastructure area to build sustainable and resilient infrastructure. However, no studies have been conducted about the slope condition in one of the road sections, Planjan-Baron, which is situated in the Gunungkidul Region. Hence, slope stability models in Planjan-Baron Section are presented in this paper. This research aims to analyze the slope condition in Planjan-Baron Section by using the Limit Equilibrium (LE) methods, i.e. Bishop Simplified, Janbu Simplified, and Morgenstern-Price. The research started with literature studies and continued with field investigation and laboratory testing. The analysis step began with slope modeling from its original condition using Slide software to determine the Factor of Safety (FS). The result showed that FS obtained on the slope reviewed at STA 3+800 was less than 1.2. This result indicated that the condition of the slope was unstable. Furthermore, this paper also showed the comparison of LE methods in the case of this study. FS results of the LE methods used showed that Bishop Simplified and Morgenstern-Price obtained almost similar results while Janbu Simplified dan Morgenstern-Price got significantly different results. Various kinds of mitigation were suggested for the slope stability of the Planjan-Baron Section to minimize the risk of landslide potential.
