Abstract
Disaster Management Agency (BNPB) reported more than 100 landslide cases in the Bogor area from January to April 2018. Topography and high rainfall intensity are predicted as the main factor in the landslide occurrence in Bogor. This study aims to develop the vulnerability map and evaluate its accuracy based on the field's landslide points. The methods proposed by the Directorate of Volcanology and Disaster Mitigation, namely DVMBG 2004 and DVMBG 2005, are used in this study. This study shows that the DVMBG 2004 resulted in the landslide-prone classification with a percentage of 74.94% and 71.92%, in 2014 and 2018, respectively. In addition, DVMBG 2005 result in the classification of hazard dominates the potential for landslides with a percentage of 71.78% and 84.58%, for 2014 and 2018, respectively. The validation results show that the vulnerability map developed by DVMBG 2004 results in 59% valid. Meanwhile, in the DVMBG 2005, all points of occurrence were validated. Hence, the DVMBG 2005 landslide estimation model is the recommended method for making landslide hazard potential maps.
