This research aims to (1) Describe the distribution of the level of hazard, vulnerability, capacity and risk of landslides in the District Gedangsari Gunungkidul Regency in a map with a scale of 1: 50.000 (2) Determine the spatial distribution of registered land parcels and Ground Control Points (GCP) on various levels of hazard, vulnerability, capacity and risk of landslides in the District Gedangsari Gunungkidul Regency.
This research combines quantitative and qualitative research methods. The data collection is carried out through interviews, observation and document study by the research unit of the village. Scoring in the making of thematic maps given as the decisive element of disaster risk maps are hazards, vulnerabilities and capacities in 67 village. Each element has indicators and score in accordance with the effect on the risk of landslides. The final score to obtain a class value of vulnerabilities, capacities and risks. This class value divided into three criterias, low, medium and high and then were presented in Landslide Hazard Map, Vulnerabilities Map, Capacity Map and Risk Map. Overlay applied to integrate the information on a landslides thematic map, Land Registration Map and GCP Map. The results of the overlay then were analyzed spatially and quantitative descriptivelly to provide land information-based landslides in Gedangsari District.
The results showed (1) Distribution of village areas with different levels of hazards, vulnerabilities, capacities and risks presented in Landslides Hazard Map, Vulnerability Map, Capacity Map and Risk Map in Gedangsari District (2) Distribution information of registered land parcels and GCP on the various level of landslides hazard, vulnerability, capacity and risk in the Gedangsari District.
The advantages of land information based landslide disaster for the National Land Agency are (1) Technical consideration in land acquisition for safe relocation and close to the disaster site, (2) GCP�s maintenance planning at the disaster site and surrounding.
