Abstract

This research use geolistric method that aims to analize the system of manifestation of fluida distribution geothermal on Diwak, Derekan Central Java, based on measurement of geolistric 3-D with pole - pole configuration, has been done. Data processing is performed using software Res3dinv and surfer which results in a horizontal and vertical cross-section. The results of the interpretation of 2D processed by software rockwork to obtain 3-D cross-section. The results showed that the measurement point 1, the direction of the fluid flow toward the east. Measurement point 2, the direction of flow of the fluid toward the northwest, the fluid flow direction to both of the points towards Lutung river. Keywords : Fluida, pole-pole konfiguration, Diwak, Derakan

Abstract

A research of refraction seismic methods in Diwak and Derekan village, Bergas district , Semarang regency , Central Java has been done on March 30, 2013 and August 27, 2013. This research in order to determination the subsurface structure of a geothermal field Diwak and Derekan with refraction method. In this aquisision data the travel time data was a distance function, with Geometrics Model ES-3000 seismic refraction instrument with 8 Geophones. Processing and interpretation data used Hagiwara method. Hagiwara method used value of delay time concept from travel time curve.This interpretation which resulted shows the subsurface lithology of the study area Diwak v1 obtained for the first layer of 297 – 412 m/s which we interpret as a layer of alluvium.  While v2 on both layers obtained a value of 471 – 697 m/s which we interpret as soil. This research is the penetration depth of 5.84 - 11.7 m . The results obtained in the field structure of the two bedding Derekan, v1 to the first layer of 546 - 1011 m/s which is interpreted as alluvium. While v2 on both layers obtained a value of 1081 - 1714 m/s are interpreted with clay .Penetration that can be recorded on the field at 0.75 – 9.16 m .Keywords: sub surface structure, seismic refraction, Hagiwara method, Diwak, Derekan
