Study of Lineament and Tectonic Structure in the Tanjung Kurung Area, Kaur Regency, Bengkulu
type: item
description: 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).

Open Mining Dataset Modeling at PT. United Tractors Semen Gresik with Artificial Neural Network Method
type: item
description: The Mining industry in Indonesia plays a vital role as a source of state income and an integral part of the industrial progress of the nation. The majority of the mining industry in Indonesia employs open-pit mining. One of the weather factors that can be an obstacle in open-pit mining is rainfall. Therefore, this research focused on modelling data from rainfall, working hours and production outcomes. It applied the Artificial Neural Network algorithm with an input layer consisting of two neurons, a hidden layer with two neurons, and an output layer. The data on Rainfall working hours, and production results were trained to produce a model that, later on, will be used to predict the value of production results. For model testing, this study uses two parameters, namely learning rate and epoch. From 90 times of testing, the best model was obtained with a learning rate value of 0.3 and an epoch of 1000 which resulted in an RMSE error of 0.004838259401280330

Analisis Kualitas Batubara Bonto Matinggi Sulawesi Selatan Untuk Kebutuhan Industri Semen
type: item
description: 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).

Effect of Sandstone Compressive Strength Value on Differences in Physical Conditions in Samarinda City, East Kalimantan Province
type: item
description: 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.

An Investigation Of Groundwater Condition By Geoelectrical Resistivity Method: A case study in Bengalon, East Kutai, East Kalimantan Province
type: item
description: Bengalon is located in East Kutai Regency, East Kalimantan Province. Bengalon is included in the Samarinda-Bontang groundwater basin. The development of agricultural and industrial areas, followed by an increase in residential areas, will cause an increase in the water demand. This study aims to determine the groundwater potential of alluvial areas using the resistivity geoelectric method. The resistivity survey resulted in subsurface lithology, shallow groundwater conditions in the form of depth, thickness, and location of the aquifer as well as the type of groundwater quality. There are 10 locations for geoelectric data collection using the 2D geoelectric method. The results showed that the majority of the aquifers were alluvial deposits consisting of sand and sandy clay. The resistance indicating groundwater is 1 - 4 Ω m, at a depth of 10 – 50 m with a thickness varying from 10 – 20 m which has been dominated by sand. The presence of sea water intrusion in aquifers causes the quality of groundwater to tend to be brackish because the research location is in a swamp area bordering the coast.

Development of Mining Area Zonation in Magetan based on Geographic Information System application with overlay method
type: item
description: Magetan has resources mineral potential of non-metallic minerals and rocks. The mineral variety is a mineral which relates to the people livelihood because it necessary for infrastructure development. There is no mining area zoning until now and it can be used to optimize the management and utilization of potential resources. In Magetan, mining area zoning was carried out by giving weights and assessments to the determining parameters which was conducted by patch method and it utilized Geographic Information System. So, the result of mining area zoning could be grouped into three zones. They were a zone could be granted a mining permit, a zone could be granted a conditional mining permit and a zone could not be granted a mining permit. Determining parameters for mining area zoning were land height, disaster vulnerability, groundwater, river borders, lakes and irrigation buildings, springs, forests and protected areas, agricultural land and cultivation areas, settlements, cultural heritage, tourism and district strategic areas, and land slope. The result of potential resources identification was carried out by analyzing Magetan geological map which was obtained potential resources, like andesite, pumice breccia, sandstone, siltstone and basalt. The zoning of Magetan mining area is a zone could bne granted a mining permit and the area was 9,914.507 Ha or about 14% in a percentage of the area, a zone could be granted a conditional mining permit covering an area of 20,748.29 Ha or about 30% and a zone unable to be granted a mining permit covering an area of 39,296.08 Ha or about 56% of the total area of Magetan.

Investigasi kondisi airtanah dengan geolistrik: studi kasus endapan aluvial di Bengalon Kutai Timur, Provinsi Kalimantan Timur Indonesia
type: item
description: Bengalon is located in East Kutai Regency, East Kalimantan Province. Bengalon is included in the Samarinda-Bontang groundwater basin. The development of agricultural and industrial areas, followed by an increase in residential areas, will cause an increase in the water demand. This study aims to determine the groundwater potential of alluvial areas using the resistivity geoelectric method. The resistivity survey resulted in subsurface lithology, shallow groundwater conditions in the form of depth, thickness, and location of the aquifer as well as the type of groundwater quality. There are 10 locations for geoelectric data collection using the 2D geoelectric method. The results showed that the majority of the aquifers were alluvial deposits consisting of sand and sandy clay. The resistance indicating groundwater is 1 - 4 Ω m, at a depth of 10 – 50 m with a thickness varying from 10 – 20 m which has been dominated by sand. The presence of sea water intrusion in aquifers causes the quality of groundwater to tend to be brackish because the research location is in a swamp area bordering the coast.

Pemetaan Sebaran Kadar Besi Pada Endapan Laterit Nikel Menggunakan Metode Interpolasi Indikator Kriging dan Ordinary Kriging
type: item
description: Beside containing nickel (Ni), nickel laterite deposits also contain other elements, including iron (Fe) which have varying levels in each layer. In this study, the distribution of Fe content in the limonite layers was carried out using the indicator kriging method to analyze the probability distribution of iron levels and ordinary kriging to analyze the variability of iron levels spatially. Fitting the variogram was undertaken by using spherical, exponential and gaussian models. The selection of the best variogram model was carried out based on the smallest root mean square error (RMSE) value, while the estimation of resource potential was calculated by the polygon extended area method. The results of the interpolation show that the distribution of iron anomaly occupies ± 83,3% of the research area with a potential resource of ±64.522.110 ton of iron. The evaluation of the interpolation results base on the root mean square standardized prediction error (RMSP) indicates that the estimation results of iron content using the ordinary kriging method are underestimated.

Optimalisasi Fragmentasi dengan Metode KUZ-RAM pada Penambangan Batu Andesit
type: item
description: The main activities at a mining site consist of stripping the overburden, unloading by blasting and surface mining, loading and transporting from the mining location to the crushing location. Blasting is an activity in mining that is carried out with the aim of dismantling the rock from its source rock into a predetermined size to facilitate further processes such as loading and crushing and a set production target. The less boulder, the better the resulting fragmentation because it will reduce the production costs for crushing the boulder to be smaller. This research focuses on blasting geometry planning as a parameter that is considered important in changing the size of the blasting rock fragmentation. The andesite blasting activity at the Batujajar 1 mine still found a fairly large percentage of rock blocks. Based on field observations, rock blocks resulting from blasting activities in the Batujajar 1 quarry are as follows: burden (B) 2.4 m, space (S) 3.1 m, stemming (T) 1.8 m, subdrilling (J ) 0 m, height (L) 6 m, into the blast hole (H) 6 m, column of explosives (Pc) 4.2 m, explosive material as much as 11.07 kg / hole. The drilling pattern applied is a staggered pattern and corner cut blasting pattern which is blasted in a row for each line with a delay time of 25 ms. The proposed geometry is calculated by calculating RL Ash 1963. With the theoretically proposed blasting geometry the results of rock chunks measuring> 80 cm according to RL Ash 1963 are 0.18%, then selected with the 1963 RL Ash theory, the results of rock fragmentation sizes are> 80 cm is 0.18%, this amount is better than the actual rock fragmentation which is still 9.11%, with the reduced number of boulders it is expected that production activities will run better.
