摘要：Gunungkidul is located in Central Java Province, Indonesia which is vulnerable to geological hazard such as floods and earthquake. However, it is also susceptible to landslide in some areas of Gunungkidul which contributes to damage and loss. The study area is located in Putat Area of Gunungkidul with the area covered of 25km2 which aligned along latitude 7° 51' 04.35"S to 7° 51' 04.35"S and longitude 110° 30' 58.15"E to 110° 33' 41.72"E. This research aims to produce a landslide susceptibility map. The factors that triggered the landslide in Gunungkidul, Special Region of Yogyakarta such as rainfall intensity and earthquake were also analysed. The parameters that caused the occurrence of landslide were determined and the landslide susceptibility map was produced using Weightage Overlay Method (WOM) in ArcGIS software. Results showed that the susceptibility map was classified into three zones which is low, moderate and high zone. The factor that triggered the landslide were identified which is heavy rainfall intensity and earthquake. As a conclusion, the ability to detect landslide susceptibility lead to a better understanding of landslide mechanisms for the research area, thus leading to an enhanced identification of the most likely failure sites within a landslide-prone area.
