Abstract
Penelitian aliran fluida panas telah dilakukan di daerah manifestasi hidrotermal Songgoriti menggunakan metode pengukuran Self-Potential. Penelitian ini bertujuan untuk mendapatkan pola aliran fluida panas dan letak kedalaman anomali fluida panas di Songgoriti, Kota Batu. Metode Self-Potential efektif digunakan untuk penelitian ini karena metode tersebut dapat digunakan untuk menentukan nilai potensial alami bawa permukaan, sehingga karakteristik beda potensial fluida panas bawah permukaan dapat ditentukan.
Pengambilan data Self-Potential menggunakan konfigurasi leap-frog dengan jumlah titik pengukuran 100 datum. Hasil pengukuran menunjukkan karakteristik fluida panas diasumsikan sebagai anomali tinggi sekitar 60 sampai 85 mV. Hal itu dikarenakan fluida panas berasosiasi dengan batuan teralterasi sehingga bersifat termal konduktif. Proses konduksi termal di daerah penelitian diindikasikan berasosiasi dengan zona alterasi hidrotermal yang menyebabkan peningkatan nilai anomali self-potential yang terdistribusi merata pada daerah tersebut dan mempengaruhi aliran lokal. Aliran fluida teridentifikasi pada kedalaman 78 hingga 150 meter dengan pola aliran mengalir dari zona manifestasi berarah ke timur dan barat.
============================================================
Thermal fluid flow research has been conducted in the Hydrothermal Songgoriti manifestation area using Self-Potential measurement method. The aim of this research is to get the thermal fluid flow pattern and the depth of thermal fluid anomaly in Songgoriti area, Batu City. An effective Self-Potential method is used for this study because the method can be used to determine the natural potential value of surface carrying, so that the potential difference characteristics of the sub-surface thermal fluid can be determined.
Self-Potential data collection using leap-frog configuration with number of datum measurement points. The results of the measurements show that the characteristics of thermal fluids are assumed to be high anomalies of about 60 to 85 mV. That's because the thermal fluid is associated with the teralterated rock so that it is thermally conductive. The thermal conduction process in the research area is indicated in association with the hydrothermal alteration zone which leads to an evenly distributed self-potential anomaly value increase in the area and influences the local flow.
The fluid flow is identified at a depth of 78 to 150 meters with flow patterns flowing from the eastward and western manifestation zones.
