Abstrak

 

Air merupakan kebutuhan pokok bagi manusia. Air tanah salah satu alternatif sebagai sumber air bersih. Penelitian ini bertujuan untuk menyelidiki potensi air tanah di Perumahan Grand Puri Bunga Nirwana, Jember. Penelitian menggunakan metode geolistrik dengan konfigurasi wenner. Panjang lintasan akuisisi data 410 meter. Jarak spasi antar elektroda (a) yang digunakan yaitu 5 m, 10 m dan 15 m. Pengulangan data (n) dilakukan sebanyak 6 kali pada masing-masing jarak spasi antar elektroda. Inversi model menggunakan software Res2Dinv. Hasil inversi berupa citra penampang lapisan bawah tanah. Nilai resistivitas yang diperoleh 0,55-371 „¦m. Potensi air tanah berada di kedalaman 38-51,8 m. Akuisisi data terletak pada koordinat 8º10,2940 S dan 113º447,20 E. Lapisan akuifer tergolong akuifer produktif sedang. Debit akuifer diprediksi kurang dari 5 liter/detik.

 

Kata kunci: geolistrik, wenner, resistivitas, akuifer

 

Abstract

 

Water is a primary human need. Groundwater is an alternative source of fresh water. This research aims to investigate the potential of groundwater at the Grand Puri Bunga Nirwana Housing, Jember. The study used the geoelectric method with a Wenner configuration. The acquisition data length is 410 meters. The distance between the electrodes used 5 m, 10 m and 15 m. Repeating data 6 times at each spacing between electrodes. Inversion of the model using Res2Dinv software. The inversion results in the form of a cross-sectional image of the underground layer. The resistivity value obtained 0.55-371 Ωm. The depthof groundwater potential is 38-51.8 m. Coordinates of data acquisition are 8º10.29'40 'S and 113º44'7.20' 'E. Aquifer layers are classified as medium productive aquifers. The predicted discharge of aquifer is less than 5 liters/second.
