Abstract

Coal in Indonesia is widely used for both export and domestic industrial needs. Domestically, it is widely used for the textile industry, power plants, and the cement industry. Coal consumption for the cement industry in Indonesia in 2022 is up to 15 million tons. In the cement industry, coal is used as a basic material for fuel in kilns. For its utilization, coal needs to know its properties. These properties can be known by proximate analysis, sulfur content analysis and calorific value. Therefore, this research aims to find out and determine whether the quality of Bonto Matinggi coal is in accordance with the coal specifications needed in the cement industry. The research method was carried out by taking two coal samples directly in the research area, namely SA I coal sample and SA II coal sample. The coal samples were then prepared and further analyzed. Analysis of coal sample quality was carried out by proximate, sulfur and calorie analysis methods. The results of proximate analysis show that the moisture content in air dried both samples have a value that is not too significant with an average value of 6.29% adb; ash content of 19.99% adb; volatile matter of 46.79% adb and fixed carbon of 39.86% adb as well as sulfur content of 0.39% adb and calories with an average of 4,692.92 cal/g. The coal in the study area does not qualify as a basic material for fuel in kilns in the cement industry. The coal in the study area, if classified according to the Classification of in Seam Coal 1998, is classified as low grade coal (according to ash content) and the coal rank includes bituminous rank (medium rank).

Abstract

Madiun Regency is an area that has abundant natural resource potential, one of which is the mining sector. The existing potential is dominated by rock commodities. The potential of rock mining materials, namely; trass, andesite, clay, and backfill. It is necessary to zoning mining areas to optimize the management and utilization of potential resources. Mining area zoning takes into account various land use parameters. The patch method is used as a reference for the weighting and assessment of each parameter using a Geographic Information System (GIS). Zoning can be grouped into Permitted Zones, Conditional Permitted Zones, and Non-permitted Zones. The parameters determining the zoning consist of the distribution of land use based on existing ones as well as spatial and regional planning plans. The results of the identification of potential resources are carried out by analyzing geological maps and obtaining potential resources, among others; sand, sandstone, andesite, trass, clay, and backfill. The results of the zoning of the Madiun Regency mining area are; the area of ​​the zone that can be granted a permit is 37,114.95 ha, the area of ​​the zone that can be granted a conditional permit is 1,090,05 ha, and the area of ​​the zone that cannot be granted a permit is 72,310.35 ha. The results of the zoning of mining areas in the Madiun Regency can be used for consideration of mining land clearing plans based on integrated data.

Abstract

Rock strength is the ability of a rock to maintain its strength until it breaks when given force. The purpose of this study is to determine the comparison of rock strength values in different physical conditions, namely natural, saturated, dry conditions and 2 wet-dry cycles on sandstones by testing uniaxial compressive strength according to SNI standards 2825-2008. The results of compressive strength testing at two different locations showed that the condition of the rocks around the Samarinda region was weak to moderate, with strength values at location 1 ranging from 1.61 – 14.31 MPa and at location 2 ranging from 8.26 – 36.27 MPa. The Elastic Modulus obtained at location 1 ranges from 1.88 -18.60 and at location 2 it ranges from 8.26 – 37.928. The more to the West from the city of Samarinda, the strength of the rocks is increasing. With the treatment of rocks that undergo repeated wet-dry processes, it does not cause a decrease in rock strength compared to the condition of rocks undergoing saturation. This is because the amount of water content that is large enough in saturated conditions results in weakening of the rock. The lower the water content, the stronger a rock.

Abstract

The Bangka Belitung Islands are an area traversed by the tin belt of Southeast Asia. This tin belt carries tin-bearing minerals and is associated with rare earth metals (LTJ). Toboali is a sub-district in South Bangka Regency. The exploration phase carried out by PT Timah made it possible to identify rare earth elements at the same time. Samples were taken using a sonic drilling machine to a depth of 5 meters. Every 1 meter 1 sample is taken which is put into a transparent plastic and labeled. There were 100 samples tested in the laboratory using X-RD (X-ray Diffraction), XRF, Scanning Electron Microscope (SEM) and Inductively Coupled Plasma (ICP). From the results of observations and laboratory analysis, it is known that there are 5 LTJ elements that are most dominantly found in each sample, namely Serium (Ce) an average of 61.92 ppm, Yttrium (Y) an average of 34.6 ppm, Lanthanum (La) an average of 27.55 ppm, Neodymium (Nd) an average of 27.55 and Samarium (Sm) an average of 2.82. Sampling or exploration using a sonic drilling machine needs to be evaluated to get a better level of sample and data accuracy

Abstract

The Muaraenim Formation is a coal-bearing formation located in the South Sumatra Basin. The research location is in the Beringin Makmur 2 area, North Musi Rawas Regency, which is included in the Airbenakat and Muaraenim Formations. The aim of this research is to do 2-dimensional and/or 3-dimensional modeling in the research area to determine the feasibility of the mining process. The feasibility test of a coal seam body will be used as a study for the next stage, namely resource estimation. The method for calculating coal resources is the USG circularS method based on drill log data. The following data is needed, such as drilling data for 64 drill points, regional geological data and survey data at the research location or mining business permit (IUP) location. Then an analysis will be carried out so that 3D subsurface modeling and calculation of coal resources can be continued. Based on the research results, it was found that there were 3 coal seams with updip in the north direction and downdip in the south direction N1800E - N1820E. In the research area, synclines were found that affected the distribution of coal. Interpretation of the 3D model is obtained from the correlation between drilling data and survey data. The results of the calculation using the USGS circular method, the estimated tonnage of inferred resources is 91,840,000 tons, indicated resources are 55,330,000 tons, measured resources are 235,870,000 tons so that the overall estimate of the coal seams is 383,040,000 million tons/ton.

Abstract

Identification and interpretation of landscape lineaments and measurements of geological structural components in rock outcrops have been carried out in order to reveal the development of rock sequence deformation in the study area. This research was conducted in Tanjung Kurung Village and its surroundings. The regional observation area is included in the Manna Enggano Sheet Geological Map (Amin, T, C. et al, 1993), while tectonically it is located in the Bengkulu basin which previous researchers categorized as a fore-arc basin (Sapiie et al ., 2015). This study uses two approaches, namely lineament analysis with national digital elevation model (DEMNas) image interpretation and surface geological mapping with observation of rock outcrops or structures. The DEMNas image used in this research has been accessed from https://tanahair.indonesia.go.id/portal-web which is owned by the Geospatial Information Agency (BIG). The geological structure of the Bengkulu Basin is divided into two general directions, namely the North-West-Southeast and North-East-Southwest directions. Structures that trend northwest-southeast are the Tanjung Sakti fault and the Ketaun fault. These faults are directly related to the Semangko Fault pattern and the Mentawai Fault pattern (Yulihanto et al., 1995).
