Abstract

ABSTRAK

Telah dilakukan penelitian tentang perkiraan temperatur reservoir panas bumi di daerah Alam Pauh Duo, Kecamatan Alam Pauh Duo, Kabupaten Solok Selatan berdasarkan resistivitas listrik silika jenuh air dan resistivitas air. Sampel teras silika dan air diambil pada 6 titik radial menjauh dari sumber mata air panas.Pada pengujian resistivitas silika jenuh air, nilai yang didapatkan yaitu berkisar antara 7,06 sampai dengan9,74 Ωm dan resistivitas air didapatkan nilai berkisar antara 57,06 dan 58,52 Ωm. Perkiraan temperatur reservoir yang dihasilkan memiliki rentang temperatur rata-rata antara 253 sampai dengan 340˚C yang dihitung menggunakan persamaan Dakhnov.Nilai ini mengindikasikan bahwa daerah di Kecamatan Alam Pauh Duo, Kabupaten Solok Selatan  berpotensi sebagai sumber pembangkit listrik tenaga panas bumi.

Abstract

The study in estimating temperature of geothermal reservoir at Alam Pauh Duo, Solok Selatan was conducted based on the electrical resistivity ofsaturated silica and resistivity of water. Silica sinter terraces and water samples were taken at six point radially away from the hot spring. Electrical resistivity of saturated silica range from 7.06 to 9.74 Ωm, while the resistivity of water range from 57.06 to 58.52 Ωm. Temperature estimation of geothermal reservoir have an average of temperature value from 253 to 340˚C, calculated using Dakhnov equation. This value indicates that the area at Alam Pauh Duo, Solok Selatan has potential as a source of geothermal power plant.
