Abstract

ABSTRACTResearch has been carried out using a gravity method that aims to interpret the subsurface structure of the Diwak - Derekan hot springs area based on the Bouguer anomaly data. It also aims to investigate the geothermal system in the area.  The data aquisition was taken using gravitymeter Lacoste & Romberg.Data processing had been done with high correction tool, tidal correction, drift correction,  gravity absolute correction, gravity theoretical correction, free air correction, Bouguer correction, terrain correction to get the complete Bouguer anomaly.  Bouguer anomolay is projected to flat plane and upward continuation is used to separate the regional and residual anomaly. For 2D modelling interpretation by Grav2DC software.The results of study showed the complete Bouguer anomaly contour pair of positive and negative contour indicate a fault zone below the surface. Interpretation is strengthened by the results of the modeling showed a  fault of Diwak - Derekan areas trending southwest- northeast. This fault zone is used as a media outlet fluid to the surface of geothermal systems.Keywords: Gravity Method, 2D modelling, Diwak, Derekan

Abstract

Steady State Modeling has been done hot springs Diwak-Derekan using Hydrotherm 2.2 software which aims to model numerically geothermal system Diwak-Derekan in Steady State conditions. The results form the output of Hydrothrem 2.2 Temperature Distribution and visualization of the data carried Temperature Distribution.Extent of the study area is 16 km x 16 km, where there is a buffer area in the outer portion of the study area. then made construction research area consisting of several slice and block research. Used topographic data using secondary data, and topographic data modeling made in accordance with the slice. Each slice of the construction area made initial research model that contains the physical parameters. Due to the limitations of the data parameters of physics, then some physical parameters of the data analogous to data from Mount Merapi and soil mechanics research data Diponegoro University Dam, physical parameters and the data is made in the form of program listings in the form of input for software Hydrothrem which Hydrotherm Software run the program until the year to 200,000 by year interval 10,000 years.The results of data visualization is seen that the temperature distribution for the data in the year to 80,000 and so no change is significant, this indicates that in the year to 80,000 already reached Steady State conditions. Khono (2000) said, geothermal system reach steady state condition between 200.000-500.000 years, its because using analogical data from Merapi Vulcano and ground mechanic Diponegoro University dam. Manifestations of geothermal systems around the emergence of hot water Diwak-Derekan a geothermal system associated with sediments. This is confirmed by studies based on the gravity method which is done around the study area, where there are faults trending down southwest - northeast parallel to Kali and Kali Jumbleng Klampok, where after a qualitative interpretation there are 4 layers of rock, where the top layer is sediment layer has a depth of about 3 km.Keywords: geothermal, fault, Distributions Temperature, geothermal systems, Steady State.
