Determine effective pedestrian paths as evacuation routes for landslide disaster (case study: manyaran and kembangarum villages)

Abstract

Central Java is one of the provinces in Indonesia that is vulnerable to natural disasters, such as earthquakes, volcanic eruptions, and landslides. Landslide incidents in Central Java from 2011-2015 have the highest frequency compared to other disasters, i.e. 568 incidents. Primarily, for landslide, the data shows that the incidents in the city of Semarang have a high frequency. The previous study about the readiness index of several villages in the city of Semarang in facing the landslide disaster has been conducted and the result indicated that 2 out 19 surveyed villages belong to the category not ready for facing the landslides, namely Manyaram and Kembangarum. One of the causes of the lack of readiness is they don’t have an evacuation route. So, based on this condition, the purpose of this study is to determine an effective pedestrian path as evacuation routes for landslide disaster for Manyaram and Kembangarum Villages. In this case, the effective pedestrian path will be determined based on the shortest, fastest, and inexpensive route parameters. The method used in this study is Network Analysis with ArcGIS10.3 applications. The result of this study will display the route map and trip descriptions of the shortest, fastest, and inexpensive route.
