Abstract
PT. Kartanegara Carbon is located in the village of Sekatak, Sekatak Buji Subdistrict, Bulungan Regency, North Kalimantan Province and has 3 IUP, named South Block, Middle Block, North Block. The potential for granite in the area to be used by PT. National Carbon by opening the mine. The absence of supporting data stating the distribution and granite resources at 3 locations of the IUP of PT. Carbon Kartanegara, encourages exploration. Exploration activities are carried out by measuring geolistyrices of 2-dimensional resistivity using a Wenner configuration of 40 tracks, which covers 80% of the area of the research area. The appearance of subsurface conditions from the results of the 2-dimensional resistivity measurements are combined to create 3dimensional modeling. 3-dimensional modeling is used to estimate the granite resources at the research location. Based on the results of research conducted, there are 2 types of granite, weathered granite and fresh granite. Weathered granite has a resistivity value of 900 – 1.950 Ωm and fresh granite has a resistivity value of > 1.950 Ωm. In the southern block the weathered granite volume is 8.928.000 m3 and the fresh granite volume is 1.338.000 m3. The middle block of weathered granite volume is 2.218.000 m3 and the fresh granite volume is 2.166.000 m3. The northern block of weathered granite volume is 5.842.000 m3 and the fresh granite volume is 3.614.000 m3. Keywords : granite, geoelectricity, modelling, resistiviy, resource.
