【 摘 要 】

This research aims to analyze the Least-Cost Path, an ArcGIS raster analysis, as a tool to find the evacuation route. The evacuation route of mount Merapi Eruption in Mriyan- Musuk of Boyolali regency in the scenario of sister village with Kiringan Village was selected as case study. There are 4 steps of analysis in this method such as; cost surface, cost distance cost backlink and cost path. This study analysis found 3 alternative routes which estimates 25-30 minute. These alternatives evacuation route are useful in distributing the flow of people when the eruption occurs.
