Abstract

Badeng River is the path of the Mount Pendil catchment area which can potentially bring avalanche material and runoff water from upstream to downstream so that it can cause floods and even flash floods. The mapping of flood and landslide-prone areas in the Badeng Watershed is non-structural disaster control. The research objective is the identification of disaster mitigation in areas prone to flooding and landslide-prone areas in the Badeng Watershed with Geographic Information Systems. The study was conducted using descriptive methods consisting of surveys and map overlays, while the identification of flood-prone and landslide-prone areas using a scoring method by weighting refers to the formula of flood and landslide susceptibility. The results showed that the flood water supply area of Badeng watershed with 32.2% prone conditions was found in the villages of Desa Sumber Arum, Sumber Bulu, Sumber Baru, Songgon, Parang Harjo, Bedewang, Kemiri, Benelan Kidul, Bubuk, Cantuk, Gintangan, Singojuruh, Alas Malang, Bayu, and Gladag. For areas prone to flooding with very prone conditions 28.43% was found in the villages of Sumber Arum and Bayu, and landslide susceptibility areas with moderately vulnerable conditions 2.7% was in the villages of Sumber Arum, Songgon, Bayu, and Sumberbulu. Disaster mitigation was recommended upstream in the form of vegetation conservation and mechanical conservation buildings and downstream in the form of river dredging and flood awareness training for communities in vulnerable areas.
