Visualized Information Value Model Result of Landslide Vulnerability in Purworejo

摘要

Indonesia is one of the disaster-prone countries. Based on the Indonesian Disaster Information Data (DIBI) and theNational Disaster Management Agency (BNPB) in the last five years from 2014 to April 2019 there have been 65landslides in Purworejo. Landslide is one of the most common disaster that occur in Indonesia. Landslide is caused bymeteorological and geomorphological factors. Purworejo is one of the potential areas that could be experiencinglandslides, because the geomorphological conditions which are included in Menoreh Hills are geographically slopingto very steep. Landslide susceptibility modeling in Purworejo Regency was carried out using three different methods,namely Information Value Model (IVM), Information Value Model-Analytical Hierarchy Process (IVM-AHP) andInformation Value Model-Gray Clustering (IVM-GC). The difference between this research and the landslidemodeling research that has been done previously is in the geovisualization section. Research that has been done tomodel landslide vulnerability is visualized in the form of a two-dimensional map. This research develops visualizationtechniques with the aim of making reading easier, increasing traction, and adding height information and impressionsto map readers.The visualization used is 3-dimensional mapping. This mapping is intended to make it easier tocompare the map results of modeling that have been done before. The expected results of this study are accurate andreliable 3-dimensional visualization to study the advantages and disadvantages of each of the modeling methods used.
