IDENTIFIKASI LAPISAN AKUIFER AIR TANAH DENGAN MENGGUNAKAN METODE GEOELEKTRISITAS KONFIGURASI SCHLUMBERGER DI TAMAN SALMA SHOFA SAMARINDA, KALIMANTAN TIMUR

Abstract

The geoelectric method is one of the geophysical methods. It studies the electrical properties on earth and detects on the surface of the earth. In this case includes the measurement of potential, currents and electromagnetic fields that occur either naturally or due to injection of current into the earth. This research was conducted at Salma Shofa garden. Geographically, the location of Salma Shofa Garden is located at 117° 12' 43.0326" E, 0° 28' 40.0238" S to 117° 13' 14.1068" E, 0° 29' 06.5236" S. In the two line was measured to obtain the values of apparent resistivity (ρa) this using the Schlumberger array. These values are processed by the IPI2win program to obtain 1-D from each line. The results of geoelectric modeling indicate the deep of ground water. The resistivity values in line 1 is 49.2Ω.m-51.8 Ω.m. and 49.2Ω.m-51.8Ω.m in line 2.
