Abstract

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.
