Analysis of Risk Assessment of Mount Merapi Eruption in Settlement Area of Sleman Regency

Abstract

Mount Merapi is one of the most active volcanoes in Indonesia. Seeing the status of Mount Merapi which until now is still quite active, disaster mitigation action efforts are needed. One of the disaster mitigation actions is by making the Risk Map. This study aims to provide an assessment of risk assessment of eruption of Mount Merapi in settlement areas so as to minimize losses that can occur. Mapping of eruption risk of Mount Merapi using two parameters, namely hazard and vulnerabilities. Risk assessment is derived from Matrix comparison of Risk Assessment. Making the risk map using processing method and spatial analysis of Geographic Information System (GIS) with scoring method, weighting, and overlay. The addition of settlement information was obtained using the Normalized Difference Built-up Index (NDBI) method to know total settlement areas. This research will produce a risk settlement area map of Mount Merapi eruption and conclusion that there is still a large risk that occurs in Sleman regency. And Remote sensing technology and GIS can answer challenges in providing disaster analysis with a fast response and better accuracy so that the need for other implementations in building disaster maps in other regions with this technology.
