METODE GEOLISTRIK KONFIGURASI WENNER DAN HIDROGEOKIMIA SEBAGAI IDENTIFIKASI AIR TANAH DANGKAL

Abstract

Water is the main requirement for human life. Therefore, a research was conducted to estimate groundwater potential using the Wenner Configuration Geoelectric Method on JalanMatoa Raya Sidomulyo Barat with coordinates N 0˚26'30,19214 '' and E 101˚24'20,3602 ''.The track used is 2 tracks with a path length of 100 meters and a space between the electrodes of 4 meters on each track. Then the data obtained were processed using Res2Dinv version 3.54.44 software. The results showed that the resistivity values varied around 360Ωm - 4839Ωm on track 1. The lithology of line 1 consisted of sand, gravel, sandstone, dry gravel and loam / marl. Line 2 for the resistivity value ranges from 243Ωm - 7769Ωm. Path lithology 2 consists of groundwater, gravel, sand, loam / marl, sandstone and dry gravel. The water quality test based on pH parameters shows that the water is acidic (pH<7), while based on the turbidity in the sample it is 0.00 which means that the water is not cloudy or clear.
