Analysis of Flood Vulnerability Level Using Geographic Information Systems in the Pangkep Urban Area

Abstract

The Pangkep Urban Area in Pangkajene and Islands Regency is one of the districts in South Sulawesi Province which is often hit by floods. The high intensity of rain triggers river overflows which is one of the causes of flooding. The formulation of the problem in this research is: what is the level of flood vulnerability, and what are the efforts to control flood disasters in the Pangkep Urban Area. In this work, flood data overlay is used to answer the first problem, and SWOT analysis is used to answer the second problem. Flood Prone Areas. Based on the results of the analysis, an area of 4464.478 hectares was obtained. The floods include Boriappaka, Tekolabbua, Anrong Appaka, Sibatua, Bonto Perak, Bontokio, Tamampua, Padoang-doangan, Jagong, Mappasaile and Samalewa sub-districts, all of which are designated as having a high level of flood vulnerability. Meanwhile, the level of moderate flood vulnerability reaches an area of 2,445,702 hectares covering the sub-districts of Pabbundukang, Sapanang, Minasatene, Biraeng, Bonto Perak and Jagong sub-districts. Implementation of a turnaround strategy (quadrant III) with adaptation and protection strategies is based on analysis of SWOT findings.
