This study aims to mitigate mass movement disasters to reduce the impact of the threat in the Wonolelo area and its surroundings, Pleret District, Bantul Regency, Yogyakarta Special Region. We carried disaster mitigation out by mapping the potential vulnerabilities of mass movements along with land use directions. The data used is in the form of parameters referring to the regulation of the Minister of Public Works Number 22/PRT/M/2007. Parameter data consists of natural factors and human factors. Natural factors such as morphology, constituent lithology, geological structure, vegetation, water conditions. Human factors such as human activity, population, and mitigation efforts. The observed data are at 25 observation points in the field. With the support of rainfall and seismicity data, we can carry an assessment of potential hazards out with a weighted value. The potential for mass movement vulnerability is in the medium and low-level mass movement-prone zones. Suggested disaster mitigation is structuring land use as horticultural agricultural land, production forest, protected forest, settlements, and food crop agriculture.

The research area is located in the Seloharjo Area, the southern hills of Opak River, Bantul Regency, Yogyakarta Special Region, Indonesia. This study explores the application of rock mass classification assessment by modifying the Q system (SQR) for rock slope stability (SMR) where the constituent lithology is platy jointed andesite. Andesite in the research area is lava haze, where currently the rock slopes are prone to rockfall since the earthquake in 2006. Correction of Q system parameters in the research area is controlled by oriented slopes and joints that were weathered into clay minerals filling the joints. Slope between 74° and 78° with strikes of the slope face between N 110° E and N 228° E. Strike direction of the planar joint plane is between N 136° E and N 238° E with an angle of dip is 20° and 26°. The presence of secondary minerals dominated by smectite and illite clay minerals. Based on the value of the RMR between 43 and 72 with the SMR value between 59.99 and 87.03, the Q value between 7.47 and 299.35, the SQR value between 84.58 and 2,564.10, the equation in the form of SMR = 7LnSQR + 30 is obtained.
