Abstract

Panas bumi dapat menjadi salah satu sumber energi alternatif terbaru pengganti bahan bakar fosil. Penelitian ini dilakukan untuk mengidentifikasi potensi panas bumi di wilayah Songgoriti Kota Batu yang termasuk dalam daftar Wilayah Kerja Panas Bumi (WKP) di Jawa Timur. Metode yang digunakan dalam penelitian ini yaitu metode geolistrik dengan konfigurasi Wenner-Schlumberger untuk mengetahui nilai distribusi tahanan jenis terukur dan karakter daerah panas bumi melalui hasil pemodelan 2D menggunakan software Res2dinv. Pengukuran data geolistrik menggunakan system multikabel untuk 7 listasan dengan panjang berturut-turut 160 m, 240 m, 240 m, 96 m, 96 m, 24 m, dan 96 m dan jarak antar elektroda 5 m, 5 m, 5 m, 4 m, 3 m, 1 m, dan 3m. Dari hasil pengolahan data diperoleh distribusi nilai resistivitaspada rentang 0,166 Ωm – 36747 Ωm dengan struktur batuan antara lain lapisan lempung pasiran, lanau pasiran, tufa pasiran, breksi tufaan, dan aglomerat.Lapisan aglomerat diduga berfungsi sebagai pemanas fluida dalam system panas bumi di wilayah ini.

Geothermal can be one of the newest alternative energy sources to replace fossil fuels. This study aims to identification of geothermal potential in the Songgoriti of Batu City which is included in the list of Geothermal Working Areas (WKP) in East Java. The method used in this study is the geoelectric method with the Wenner-Schlumberger configuration to determine the measured resistivity distribution value and the character of the geothermal region through the results of 2D modeling using Res2dinv software. Geoelectric data measurements used a multicable system for 7 tracks with 160 m, 240 m, 240 m, 96 m, 96 m, 24 m, and 96 m respectively and 5 m, 5 m, 5 m, 4 m, 3 m, 1 m, and 3 m between electrodes. From the results of data processing, the distribution of resistivity values in the range 0.166 Ωm - 36747 Ωm with rock structures such as sandy clay, sandy silt, sandy tuff, tuffaceous breccia, and agglomerates. Agglomerate layers are thought to function as fluid heaters in geothermal systems in this region.
