Enhancing Disaster Mitigation: Mobile-GIS Sister Village Evacuation Route System for Mount Merapi Eruption in Yogyakarta.

The Mobile-GIS Sister Village Evacuation Route (MSVER) system was devised and implemented in order to enhance Yogyakarta’s Mount Merapi eruption mitigation and evacuation. The 2010 eruption of Mount Merapi, with its pyroclastic flows and volcanic ashfall, posed a threat to local residents. In response, the Center for Volcanology and Geological Disaster Mitigation (PVMBG) issued evacuation orders with variable safe zone radii, necessitating meticulous route planning and communication. This study suggests MSVER, which utilizes GIS and Sister Villages to address these problems. Using GIS on mobile devices, the system provides real-time data on disaster-prone areas, evacuation routes, meeting points, and disaster-resistant villages. The BPPTKG provides status updates for Mount Merapi. MSVER system development involves establishing optimization criteria for evacuation routes, such as distance, speed, density, and obstacles. The Merapi Evacuation Route app helps users locate danger zones, discover evacuation routes and gathering sites, and comprehend Mount Merapi’s eruption status and risks. It also contains information on the population and disaster-resilient villages. In conclusion, the MSVER system employs GIS and Sister Villages to assist communities in Yogyakarta in preparing for and responding to Mount Merapi eruptions. This ingenious strategy saves lives and serves as an example of how to use indigenous knowledge and technology to combat natural disasters.
