Abstract

Landslide is a natural disaster that commonly happens in Indonesia, especially in Region of Semarang that geologically has hilly topography. In Semarang city, there are 22 Sub Districts classified as landslide potential areas, which one of them is Sub District Ngesrep, based on to BPBD Semarang. The disaster of landslides can cause human injuries and loss in infrastructure, life, and assets. Disaster management requires identifying for the impact of landslide disaster at a location. One of the methods to identifying the impact of landslide disaster uses UAV technology. UAV technology can be used to collect, map, extract information of landslide and build Digital Model in surface or elevation based on overlapping imageries. Elevation data from UAV are combined with data of rainfall, land cover and geological which will produce the map of the potential landslide disaster. The map of the potential landslide disaster is combined with the result of land cover digitation to determine the impact of landslide disaster.

Summary

Introduction

Indonesia region is located in the tropical climate area with two seasons that is summer and winter with characteristics of weather changes, temperature and wind direction is quite extreme. The condition can cause some bad consequences for humans such as the occurrence of hydro meteorological disasters such as floods, landslides, forest fires, and drought. Landslide is a natural disaster that commonly happens in Indonesia, especially in Region of Semarang that geologically has hilly topography. In 2016, in the Bukitsari region of Sub District Ngesrep, cases of the landslide had been happening on October 4, 2016. This disaster causes human injuries but loss in infrastructure, life, and assets.
