Abstract

Abstract Keteguhan Village is an area that has the highly potential to flood disaster, such as the flash flood incident that occurred on March 30, 2020. Floodprone mapping is needed to map flood prone potentials in SKeteguhan Village with the aim of increasing the alertness and readiness of the Keteguhan Village’s community in dealing that disaster. The used method includes processing the parameters of rainfall, land cover, slope, soil type, land height and land cover, then carried out by a weighted overlay process to form new data in the form of a flood prone potential map. The obtained results are that there are 3 potential areas, namely the lowlands along the river area of Umbul Kunci Street, the river area in the nearest neighborhood of Keteguhan Village and Mushollah Nurul Jannah on Laksamana R.E. Martadinata Street. Based on the area of vulnerability level in Keteguhan Village, the safe category has an area of up to 137,451 Ha with a percentage of 44.6%, the non-prone category has an area of up to 95,5116 Ha with a percentage of 30.01%, the vulnerable category has an area of up to 62.4922 Ha with a percentage of 20.27% and the very vulnerable category has area up to 15.7767 Ha with a percentage of 5.12%.
