Abstract
Kayangan Api merupakan fenomena geologi alam berupa
api abadi yang terletak di Kabupaten Bojonegoro, Jawa Timur.
Semburan gas ini karena adanya gas yang merembes melalui
patahan menuju ke permukaan bumi. Hal ini mengindikasikan
bahwa di Bojonegoro memiliki cadangan hidrokarbon gas yang
melimpah. Untuk mengetahui tentang arah dan posisi patahan di daerah Kayangan Api, dilakukan pengukuran menggunakan
metode geolistrik 2-D konfigurasi Wenner-Schlumberger. Proses analisa data menggunakan metode Occam. Diperoleh model 2 dimensi kontur resistivitas yang menggambarkan bawah
permukaan berdasarkan nilai resistivitas batuan. Hasilnya ialah terdapat anomali konduktif yang diidentifikasi dengan adanya suatu patahan. Patahan pada anomali konduktif disebabkan karena patahan tersebut tersaturasi fluida. Patahan dangkal di Kayangan Api ini memiliki arah Barat Daya menuju ke arah Timur Laut.

Kayangan Api is natural geological phenomena of eternal flame that located in Bojonegoro, East Java. Gas bursts appear caused gas seeping to the surface of the earth through a fracture. This is indicates that in Bojonegoro has abundant gas reserves. Therefore, geolectric 2-D method with Wenner-Schlumberger configuration used to identify direction and position of fracture. The least-square inversion using Occam technique process is performed on measurement data by ZondRes2D software. The result is a two dimensional model of resistivity contour that describes the subsurface based on the resistivity value of rocks. The result is that there are conductive anomaly identified by the presence of a fracture. Fractures in conductive anomalies are caused the fracture is saturated fluid. Interpretation results showed that the direction of fracture is Southwest to Northeastt.
