Determining the potential of quartz sand in the Pasir Putih Village, District of Pendolo, Regency of Poso

This research aims to investigate the potential of quartz sand in Pasir Putih Village of Pamona Selatan District, Poso Regency. The research is conducted by using a method of geoelectrical resistivity with Schlumberger configuration. Mapping process was done at 37 points of measurement and calculated using IP2WIN software. Each measurement point is connected to 5 trajectories in order to map the potential distribution of quartz sand. The software of 3D RockWork is used to calculate the volume of white sand at the research area. The results obtained are detected white sand with a resistance value of 1000 Ωm - 140,000 Ωm to a depth of 100 meters below level ground for lanes 1 and 2 which is located adjacent to Poso Lake. The existence of white sand distribution decreases with distance away from Poso Lake (trajectory 3, trajectory 4 and trajectory 5). Calculated volume of quartz sand at this study location was 134.56 million m3 with measurement area of 2.151.498 m2.
