Abstract

Penelitian tentang keberadaan air tanah telah dilakukan menggunakan metode geolistrik resistivitas konfigurasi Schlumberger. Penelitian ini dilakukan di Desa Clapar Kabupaten Banjarnegara. Akuisisi data menggunakan dua titik pengukuran dengan bentangan hingga 200 meter, dan jarak antar kedua titik pengukuran sebesar 100 meter. Hasil penelitian menunjukkan bahwa sebaran nilai resistivitas secara sounding pada titik pertama sebesar 0,33 - 377 Ωm, dengan kedalaman hingga 70 meter. Keberadaan air tanah pada titik pertama diduga terdapat pada akuifer bebas dengan kedalaman 3,09 - 17,6 meter (ketebalan 14,51 meter), dan akuifer tertekan dengan kedalaman 24,8 - 50,5 meter (ketebalan 25,7 meter). Sedangkan sebaran nilai resistivitas secara sounding pada titik kedua sebesar 7,21 - 1.281 Ωm, dengan kedalaman hingga 70 meter. Keberadaan air tanah pada titik kedua diduga terdapat pada akuifer bebas dengan kedalaman 5,22 - 9,82 meter (ketebalan 4,6 meter), dan akuifer tertekan dengan kedalaman 37 "“ 63,9 meter (ketebalan 26,9 meter). Hasil penelitian juga menunjukkan bahwa akuifer bebas diinterpretasi berupa litologi pasir lempungan, sedangkan akuifer tertekan diinterpretasi berupa litologi pasir hingga pasir kerikilan.
