Abstract

Pemandian Air Panas Kalipanas yang terletak di Kecamatan Singgahan, Kabupaten Tuban merupakan salah satu indikator keberadaan sistem panas bumi di permukaan yang memiliki potensi untuk dikembangkan. Namun, hingga kini, penelitian geofisika yang mengungkap kondisi bawah permukaan di area ini masih terbatas. Penelitian ini dilakukan untuk memetakan pola sebaran air panas dan memahami karakteristik nilai resistivitas batuan di bawah permukaan dengan menggunakan metode geolistrik resistivitas konfigurasi Schlumberger. Pengukuran dilakukan di lima lintasan dengan panjang antara 130 hingga 350 meter, menggunakan alat resistivity-meter Tigre Campus. Data yang diperoleh diolah menggunakan perangkat lunak IPI2WIN dan PROGRESS untuk membentuk model resistivitas satu dimensi (1D) dari bawah permukaan. Selanjutnya, dilakukan interpretasi terhadap variasi
nilai resistivitas dan ketebalan tiap lapisan guna mengenali zona alterasi, rembesan air panas, serta jenis batuan yang menyusunnya. Dari hasil analisis, ditemukan zona dengan nilai resistivitas sangat rendah (<5 Ωm) pada kedalaman 10 hingga 60 meter. Zona ini diinterpretasikan sebagai daerah alterasi atau jalur tempat fluida panas bergerak naik.
Sementara itu, lapisan dengan nilai resistivitas tinggi (>30 Ωm) diasosiasikan dengan batuan padat seperti tufa dan konglomerat yang berperan sebagai penutup dari sistem tersebut. Secara keseluruhan, kelima lintasan pengukuran menunjukkan pola resistivitas yang mengindikasikan
keberadaan sistem hidrotermal, sehingga area Kalipanas memiliki potensi besar untuk dikembangkan dalam studi dan eksplorasi panas bumi lebih lanjut. = The Kalipanas Hot Spring, located in Singgahan District, Tuban Regency, is one of the indicators of the existence of a geothermal system on the surface that has the potential to be developed. However, to date, geophysical research revealing the subsurface conditions in this area remains limited. This study was conducted to map the distribution pattern of hot springs
and understand the characteristics of subsurface rock resistivity values using the Schlumberger resistivity geophysical method. Measurements were taken along five transects ranging from 130 to 350 meters in length, using the Tigre Campus resistivity meter. The data obtained were
processed using IPI2WIN and PROGRESS software to form a one-dimensional (1D) resistivity model of the subsurface. Subsequently, an interpretation was made of the variations in resistivity values and the thickness of each layer to identify alteration zones, hot water seepage, and the types of rocks that compose them. The analysis revealed zones with very low resistivity values (<5 Ωm) at depths of 10 to 60 meters. These zones were interpreted as alteration zones
or pathways through which hot fluids rise. Meanwhile, layers with high resistivity values (>30 Ωm) were associated with dense rocks such as tuff and conglomerate, which act as the cap of the system. Overall, the five measurement profiles exhibit resistivity patterns indicating the presence of a hydrothermal system, thereby conferring significant potential for further geothermal study and exploration in the Kalipanas area.
