Analysis of Local Spatial Data Infrastructure to Support Volcanic Mudflow Mitigation in Putih River, Magelang Regency, Central Java Province, Indonesia

One of the devastating disasters in Indonesia was Mount Merapi eruption in 2010. Post eruption there’s still occur secondary hazard of volcanic mudflow which caused damage and casualties. Volcanic mudflow is a mixture of pyroclastic material and rain water, so that in the rainy season the area along the river becomes a high hazard of volcanic mudflow. One of the high hazard areas is along Putih River in Magelang Regency, Central Java Province.

The development of Spatial Data Infrastructure (SDI) plays an important role in disaster management, especially in disaster mitigation efforts. Building Spatial Data Infrastructure which share information and spatial condition of area along Putih River can save many lives and reduce the risk from volcanic mudflow. This research carried by conducting interview surveys, field surveys and secondary data collection at government institutions. The results of the analysis is a geoportal prototype as an information gateway for mitigation of volcanic mudflow in Putih River for government and community. This research is expected to be able to contribute to the government and community for reducing disaster risk.
