Efforts to Improve Community Awareness Towards the Potential of a Great Earthquake Which Threats Jakarta Based on Geographic Information and 3D Simulation Systems in Matraman District, East Jakarta

Abstract

Indonesia is located in an area of active tectonic plate. This area suffers from natural disasters. Recorded almost every year disasters, such as earthquakes, tsunamis, floods, and fires, occur in several regions in Indonesia. One of the major city in Indonesia is Jakarta. Jakarta as a capital city with urban area has an important position in terms of economy and government. The issue of earthquakes with the magnitude of 8 SR is one of the major disasters that threatening Jakarta. The effort to alleviate losses caused by disasters, it is necessary to inform the community regarding preparation in the face of disasters that will occur. This preparation is needed especially in densely populated areas as part of disaster mitigation measures like Matraman District in East Jakarta. The initial step in this program is to distribute questionnaires to determine the level of knowledge and information about the disaster. Furthermore, by utilising the geographical information system (GIS), evacuation routes when a disaster occurs can be made to adjust the situation of the area. The evacuation routes produced include the fastest and safest routes in evacuation by considering conditions such as road width, car parking, electricity poles, railroad crossings, and blind alley. This evacuation route will be modelled with 3D simulation in several conditions such as railroad crossings, spill markets, crossroads, and one-way lanes when a disaster occurs. This simulation will be the end result in a program to increase public awareness of potential disasters that threaten their area. This research obtains evacuation routes and 3D simulations that have been made are information media that can facilitate people to get the right knowledge about disaster mitigation. The results of the community awareness raising program on potential disasters can be used as a reference for other regions in the effort to mitigate disasters.
