Abstract

Sorong City, especially in the Saoka area, has a hypothetical gabbro resource of 25,000,000 m3, and in the Rufei area it has a hypothetical serpentinite resource of 500,000 m3. but there is no test on the physical properties of the two rocks, so it is necessary to test the physical properties of gabbro and serpentine to determine the parameters of physical properties such as bulk density, specific gravity, water content, porosity, void ratio, and degree of saturation. The research method used is quantitative by taking samples at the research location and then conducting tests in the laboratory, the test results show the average physical properties of gabbro, namely original bulk weight = 3.09 gr/cm3, dry bulk weight = 3.01 gr/ cm3, saturated weight = 3.13 g/cm3, apperent specific gravity = 3.01, true specific gravity = 3.41, original water content = 2.55%, saturated water content = 3.91%, degree of saturation = 66.15%, porosity = 11.78%, void ratio = 0.13. Meanwhile, serpentinite has an average density of original = 2.57 gr/cm3, dry weight = 2.55 gr/cm3, saturated weight = 2.59 gr/cm3, apperent specific gravity = 2.55, true specific gravity = 2.67, original water content = 0.9%, saturated water content = 1.76%, degree of saturation = 48.19%, porosity = 4.46%, void ratio = 0.04.

Abstract

Geolistrik is one of the geophysical method used in shallow exploration. In working principle of the method geolistrik is studying the flow of electricity in the Earth, and how to detect it at the Earth's surface. This research aims to determine the water bearer layer, layout and depth as well as the type of aquifer groundwater Kampung Horna Baru and Kampung Muturi District Manimeri District of West Papua Province Bintuni Straits Bay with the method of resistivity (Resistivity). Resistivity method based on Ohm's law, aims to find out the type of coating the rocks based on the distribution of the resistivity value on each layer. Data measurement results in the field of potential noun and current can be used to calculate the price of a pseudo resistivity. After pseudo resistivity value obtained then incorporated into the software, and data res2dinv spaced electrodes and data datum points for knowing the value of resistivity, the RMSE and depth of each layer with a 2D model are vetically through a process of inverse. Geolistrik research results indicate that the aquifer groundwater Kampung Horna Baru and Kampung Muturi District Manimeri district of Bay of Bintuni Straits, has a varied range of resistivity of 0.183 meters% uFFFD Ohm. 3714 Ohm. ft. On tracks 2, 3, 5 and 6 in Kampung Horna Baru at a depth of 4.3% uFFFD 27.1 m. Whereas in Kampung Muturi on tracks 8 and 9 with a depth of 13.1-27.1 m.
