Abstract

Special Region of Yogyakarta is a province that is quite densely populated due to many migrants and domestic and foreign tourists visiting and settling in the province. This will have an impact on increasing land needs and meeting needs that can have an impact on declining environmental quality, one of which is the flood disaster. Flood disaster is a serious problem that occurs in the Special Region of Yogyakarta because almost every year floods always occur when the rainy season arrives. This study discusses the analysis of the level of vulnerability of flood disasters in the Opak watershed area with the method used is the scoring and weighting method based on the Regulation of the Head of BNPB Number 2 of 2012 concerning General Guidelines for Disaster Risk Assessment. To determine the level of vulnerability to flooding, only two variables are used, namely physical vulnerability and environmental vulnerability. Of the two vulnerabilities has a total of 6 parameters which include land use, topographic height, distance from the river, slope, Normalized Different Vegetation Index (NDVI), and Topographic Wetness Index (TWI). Based on the results of the analysis that has been done, it can be concluded that the level of vulnerability of flood disasters in the Opak watershed is included in the medium class.
