Use of drones to determine potential locations of reservoir to anticipate water crisis in Weninggalih Village, Jonggol District, Bogor Regency, West Java

Abstract

Weninggalih village experiences drought that keeps recurring every year which has an impact on the people in the area. The purpose of this study was to determine the potential location for the construction of a reservoir to anticipate water crisis in Weninggalih Village, Jonggol Districts, Bogor Regency. The research method used is a survey method to determine the sampling location and quantitative methods are used for analysis. The field survey used a drones for aerial photo data recording. Sampling was determined purposively based on the Digital Elevation Model in three dimensions from the resulting aerial photos. Quantitative methods are used to determine the potential location of the reservoir. The results showed that there were 6.609 photos taken with the drone flying at a height of 150 meters above ground level with 80% overlap. Based on the results show that there are three potential locations of reservoirs. The first potential sites of reservoir is in the area of 423 m2. The second one potential sites of reservoirs 1.415 m2 and the last one potential site of reservoirs are in area three land area of 1.191 m2.
