Kajian Tingkat Kerentanan Bencana Banjir Bandang di Kecamatan Cipatujah Kabupaten Tasikmalaya

Abstract

Abstract. Flash floods in the South West Java region have had an impact on the Cipatujah area, especially in the ten villages there. The risk arising from the flash flood loss was estimated at 28,856,000,000 rupiah, six people were washed away in the river until four people were found dead and two people missing. In addition, 376 houses were damaged in Cipatujah Subdistrict, of which 104 were slightly damaged, 88 were moderately damaged and 184 were heavily damaged. The impact of the flash floods was the destruction of infrastructure which caused the paralysis of community activities in the Cipatujah and surrounding sub-districts, so it is important to know the level of social, physical and economic vulnerability in facing floods so that recommendations to minimize the risks posed are the objectives of this study. Vulnerability level assessment is carried out using quantitative methods with weighting and scoring analysis techniques according to Perka BNPB No. 2 of 2012 and for flood prone assessments overlay / superimpose analysis techniques were carried out. The results of this study show high social vulnerability in the villages of Cipatujah, Darawati Village, and Bantarkalong Village. The high economic vulnerability is in Kertasari Village, and high physical vulnerability is in Cipatujah Village. The results of the flood-prone analysis showed that 64.75% of the areas in Cipatujah Subdistrict belonged to the somewhat flood-prone category, 16.11% were slightly prone to flooding, 19.10% were prone to flooding and 0.36% were prone to flooding, especially in coastal areas such as Ciheras Village, Cipatujah Village, and Ciandum Village.
