Abstract

Landslide is a hydrometeorologycal disaster that usually happens in Indonesia. The purpose of this study was to determine the level of landslide vulnerability in Banjarnegara District. This study employed survey and descriptive quantitative methods by using a formula of landslide vulnerability, with variables: natural and management factors. The analysis used in this study was overlaying the predetermined formula and weighting it. The results indicated a variety of vulnerability classes, which were: 1) non-vulnerable zone of 44.88 ha (0.04%), 2) slightly vulnerable zone of 7,800.84 ha (7.29%), 3) fairly vulnerable zone of 88,505.80 ha (82.74%), 4) vulnerable zone of 10,423.32 ha (9.74%), and 5) very vulnerable zone of 196.16 ha (0.18%). The dominant parameters for landslides in Bajarnegara were: rain, geology and regolith. Mitigation techniques employed in those areas should be based on community-self-supporting mitigation through the development of disaster resilient villages. Disaster resilient village is a village that is responsive and can minimize disaster risks through adaptation. Several measures can be done independently autonomously by the community including increase the alertness during rainy period, seal all cracked soil due to the fault movement, and protect the soils through slope (stabilization and protection of slopes).
