Abstract

Geoelectric resistivity method is one method that can be used to characterize water-bearing rock layers (aquifers). This method is based on the existence of differences in type resistivity in the layers of rock that are flowed electrically. The use of this method is based on easy application, faster data acquisition with broad data coverage (lateral and vertical), and lower costs. Data acquisition uses two configurations or electrode arrangement, namely sclumberger and wenner-schlumberger configurations. The number of trajectories for data acquisition uses one path with a total of 28 electrodes and the spacing between the electrodes is 20 meters. The data obtained in the form of data resistivity type of each underground layer and its depth will be further analyzed using AGISSAdmin software. The results are obtained in the form of a 2-dimensional (2D) cross-sectional value of underground layers laterally and vertically. The low resistivity value will be interpreted as a layer containing ground water, which was previously corrected against the geological and hydrological data of the area. From the cross section of the type resistors, values of 20 - 317 Ωm were obtained for the wenner and wenner-schlumberger arrangements. Selaru Village consists of two rocks unit, the first rock (≤ 120 Ohm.m) in the form of Tanjung Formation rocks, with large porosity and small permeability and groundwater potential in this unit is small (0 - 40 m depth). The second rock (≥ 120 Ohm.m) is Pre Tertiary, with very little porosity and permeability, except secondary porosity in rock fractures.

Abstract

Research has been carried out to detect the presence and distribution of rocks containing metallic minerals. Almost every object used every day contains metal elements, so the presence of metal is very important to support every human activity. The presence of metal minerals in nature is generally quite a lot, but the types of metallic minerals vary. The geomagnetic method is a geophysical method that can detect subsurface rocks containing metallic minerals based on the difference in the magnetic field between the rock and the surrounding rock. Processing of geomagnetic data obtained in the field begins with daily correction and correction of the earth's main magnetic field (IGRF). The correction results obtained are anomaly of the earth's magnetic field which is distributed horizontally on the surface. The results of the analysis in the form of local magnetic field anomalies (∆H) are divided into 3 (three) regions, the first having a value between -236.5 nT to -8 nT (nano tesla) as an area that has a high local magnetic field anomaly value. Second, the value of -377.2 nT to -236.4 nT as an area that has a moderate anomaly value. Third, the low anomaly values ranged from -778.4 nT to -377.1 nT. Areas that have high local magnetic field anomaly values are interpreted as ultramafic rocks, which are source rocks of nickel lateric deposits rich in ferromagnesian minerals, distributed in the southeastern part of the study area.

Abstract

Subur Makmur Village is an area where the availability of clean water is difficult, especially during the dry season. One of the sources of water that can be used by the villagers is groundwater. However, to obtain groundwater, it is necessary to drill wells and investigate the aquifer layer first. This study aims to obtain an overview of the subsurface layers based on the resistivity properties of the rock, so that the aquifer layer can be identified and can determine the exact location of the drill point in the prospective aquifer position that may be encountered. The geoelectric method is the most efficient method for detecting aquifer layers. It uses two types of configurations, namely, the Wenner and Wenner-Schlumberger configurations where the number of geoelectric paths is one path. The length of the track used is 540 meters, the number of electrodes is 28 with the spacing between the electrodes is 20 meters. The resistivity cross section for both configurations, obtained resistivity values of 11 - 140 Ohm meters. Composed of 2 (two) rock units, namely graywacke sandstone rock units. Consists of graywacke sandstones with claystone inserts. Density value ≥ 40 Ohm meter. Hydraulic properties, small porosity, small permeability, the potential for groundwater in this unit is small. The position of this unit is at a depth of 40 m. In the cross section, the resistivity is yellow - red. The second rock unit comprising this trajectory is the alteration claystone unit consisting of claystone containing bolders of sandstone / igneous rock. Resistivity value ≤ 40 Ohm meter. The position of this unit is on the Surface to a depth of 40 m. Hydraulic properties, large porosity with very small permeability, the potential for groundwater is very small. In the cross section of this unit resistivity are colored dark blue, blue and green. From the resistivity cross section, it can be determined the position of the borehole which is effectively located in the length range of the trajectory between 360 - 420 meters. Keywords: subur makmur, groundwater, wenner,  wenner-schlumberger

Abstract

Cempaka Diamond Panning is a location for traditionally processed diamond and gold panning located in Cempaka sub-district, Banjarbaru city, South Kalimantan. Mining activities cannot be separated from matters relating to the management of natural resources, which apart from providing benefits, there are also impacts or losses from these activities, especially for the environment. The diamond mine in Cempaka is included in the critical category which has the potential to flood when there is high intensity rain. Therefore, it is necessary to carry out geohydrological analysis using remote sensing. The method used is overlay and weighting by weighting spatial and non-spatial parameters in an area of 3189 Ha. From the results of the analysis, it is known that around 3057.61 Ha of the Cempaka region of interest (ROI) area is included in the flood-prone area and 75.88 Ha of the Cempaka region of interest (ROI) area is a slightly vulnerable area with information about three affected villages, namely Sungai Tiung, Bangkal and Cempaka.

Abstract

Kualitas batubara merupakan parameter utama dalam menentukan sebuah kegiatan baik pengolahan maupun pemanfaatan bahan galian. Kualitas suatu batubara ini juga dapat ditentukan dengan menganalisa parameter kualitas batubaranya baik secara fisik maupun secara kimiawi. Kualitas batubara juga dipengaruhi oleh kondisi geologi daerah penambangan, baik batubara dengan kadar tinggi, sedang, maupun rendah. Kehadiran karbon di setiap lapisan bervariasi dalam kualitas dan kuantitas. Untuk memperjelas, perusahaan memperkenalkan kontrol kualitas batubara berdasarkan parameter kualitas batubara untuk mengontrol kualitas batubara dari depan tambang hingga penyimpanan, sehingga berbagai metode parameter batubara diuji untuk memenuhi permintaan konsumen. Permasalahan yang timbul dari kualitas batubara ini adalah adanya keluhan konsumen tentang kualitas batubara yang menyimpang dari standar kualitas batubara yang telah disepakati bersama. Oleh karena itu perlu dilakukan analisis kualitas batubara di area pit, stock ROM serta crushing plant untuk mengetahui kualitasnya dan faktor apa yang menjadi penyebab perbedaan kualitas batubara tersebut, sehingga dapat dilakukan upaya untuk mengurangi atau meminimalisir kualitas batubara yang menyimpang tersebut.
