Abstract

Summary

Research using magnetic method has been done on geothermal area located in Parangtritis, Yogyakarta. This geothermal system is often called Parangwedang geothermal system. This research aims to map alteration zones and predict the existence of heat source in Parangwedang geothermal system. The research was conducted by acquiring magnetic method data on 2x1 km2 area around the manifestation of parangwedang hot water with measuring point in the form of uniform grid with the number of 174 points of measurement and spacing between the points 100 m. The result of the magnetic method is a total magnetic field anomaly map that will be analyzed qualitatively to determine the extent of the alteration zone and the predicted presence of heat source. The alteration zone is mapped to a low magnetic anomaly located in the southwest of the research area. The existence of heat source is suspected to be in a high magnetic anomaly located just below the manifestation of hot water parangwedang.
