Kajian Spasial Tingkat Kerentanan Rumah Tangga di Kawasan Rawan Bencana Jatuhan Piroklastik Gunungapi Kelud

Abstract

This research was conducted in the Kutut hamlet, Pandansari village, where located on the area that potentially affected by tephra fall and heavy ash fall and also located on third ring of disaster prone area of Kelud Volcano. Kutut hamlet has 235 of household. This hamlet is one of the worst affected area during eruption of Kelud Volcano in 2014. On of effort on disaster risk reduction to face pyroclastic flow which threatens on the future can be done through vulnerability analysis. The aims of this study is to determine the spatial distribution of vulnerability household’s level in the Kutut Hamlet. The unit of analysis is the household. Data were collected through the census and image interpretation. Image interpretation used to make building block map and determine the types of roofs. This study mapped the vulnerability considering four types of vulnerabilities (physical, social, economic, and environmental). Spatial Multi Criteria Evaluation (SMCE) Method used as the data analysis. This method can combine spatial and non-spatial data which is expected to produce a balanced decision. The results of physical vulnerability analysis there are 18.3 % of household categorized as high vulnerability. Social vulnerability level generate that 14.9 % of household categorized as high vulnerability. Economic vulnerability level generate 21.3 % of household, and environment vulnerability generate 13.2 % of household.
