Abstract

Swabakar is an event where coal can burn on its own. The purpose of the PT Bukit Asam Tbk Laboratory is to analyze the influence of wind speed and grain size differences and determine the value of transition temperature and the normality test of time and temperature data of coal samples. The research method used is to measure wind speed using an anemometer and measure the coal temperature before and after the swab. It can be seen from the results of the discussion that coal with a grain size of 13 mm experiences a faster swab process than coal with a grain size of 50 mm. The results showed that coal with a grain size of 13 mm experienced a faster swab than a size of 50 mm. The order of transition temperature values based on the grain size of 13 mm was MT-46 < BB-50 < AL-55, while at 50 mm the same results were found. This shows that MT-46 coal is more susceptible to swabbing than other types. Normality testing of time and temperature data shows that all data are distributed normally, so the validity of the research results can be accounted for. This study concludes that the smaller the size of the coal grains, the faster the oxidation process leads to spontaneous combustion. Wind speed also plays a role in accelerating the spread of oxygen into the coal pile, which increases the risk of swabbing. The implications of this study are important for the coal mining industry to consider the factors of grain size and wind speed in stockpile management to reduce the risk of waste and maintain the quality of coal.

Abstract

This study aims to conduct an in-depth study and evaluation of the geometry of the haul roads used by dump trucks from the Front Pit I mining area to the Disposal Area in the operational area of ​​PT Long Daliq Primacoal. The background of this study is the understanding that haul roads are the lifeblood of mining activities whose efficiency greatly determines productivity. Haul road geometry that does not comply with technical and safety standards can trigger various serious operational risks. These problems can not only cause fatal accidents that endanger operators, but also result in premature damage to vital equipment components such as tires and suspension, and cause a decrease in overburden transport efficiency due to slow cycle times and increased fuel consumption. In this study, the methodology applied was a direct survey in the field to collect actual data. The data was then processed through quantitative analysis to assess key parameters of the road geometry, including road width on straight and curved segments, slope level (grade), and curve radius. The results of the study indicate that the existing condition at PT Long Daliq Primacoal has several significant deficiencies, such as several road segments whose width is inadequate for two-way traffic and slope levels that exceed safe limits. Based on these findings, several technical improvements, such as road widening and slope smoothing, are recommended to increase safety factors and optimize overburden transport efficiency in a sustainable manner.

Abstract

PT Bumi Merapi Energi (BME) faces challenges in optimizing the use of industrial diesel fuel for its transport fleet, which is crucial for operational cost efficiency. The company relies on 30-ton class dump trucks to transport coal, so planning fuel consumption in line with production targets is a top priority. This research was conducted at the Kungkilan Block mining site of PT BME, which is administratively located in Muara Maung Village, West Merapi District, Lahat Regency, South Sumatra. The coal loading process in the pit area uses a loading tool in the form of a Hyundai K40 excavator. The effectiveness of this operational activity is greatly influenced by various factors, including dynamic work area conditions, the applied loading methods and patterns, and the cycle time of the loading equipment. Analysis of these factors is important to understand the productivity of the equipment and the required fuel consumption. This study calculates the total actual fuel consumption of the Renault K40 dump truck unit. Based on operational data during day and night shifts, it was found that the total diesel fuel consumption for one unit reached 134,910,650 in relevant units (e.g., Rupiah or liters, depending on the original context of the study), which highlights the large energy costs in the production cycle.

Abstract

The coal mining industry operated by PT Bakti Nugraha Yuda produces acid mine drainage, the management of which is crucial to prevent environmental pollution. The main problem faced is the high acidity level of the wastewater, with an initial pH ranging from 4.3 to 5.1, which is below the government's environmental quality standards that require a pH above 6. This study aims to analyze the effectiveness of using quicklime as a neutralizing agent to manage acid mine drainage at the site. This research includes quantitative research with case study research methods and analytical experiments with jar test laboratory tests and periodic pH measurements in two Sludge Settling Ponds (KPL 1 and KPL 2). The results showed that quicklime is very effective. Doses between 0.6 and 1 gram per liter successfully increased the water pH from an initial condition of around 4.5 to within the range of 7 to 8.9, in accordance with quality standards. Linear regression analysis at KPL 1 also showed a very strong correlation (R² = 0.9988) between the dose given and the increase in pH.

Abstract

Manajemen stockpile batubara memiliki peranan penting dalam menjaga kualitas batubara dan mencegah terjadinya swabakar (self-combustion) akibat proses oksidasi di dalam timbunan. Pola penimbunan yang tidak tepat, dimensi timbunan yang berlebihan, serta tidak diterapkannya sistem pengelolaan batubara yang baik dapat meningkatkan risiko akumulasi panas dan kebakaran spontan. Penelitian ini bertujuan untuk menganalisis pola penimbunan batubara yang diterapkan pada area stockpile PT Lematang Coal Lestari serta mengevaluasi efektivitasnya dalam mencegah swabakar. Metode penelitian yang digunakan adalah deskriptif kualitatif melalui observasi lapangan, wawancara, pengumpulan data, dan analisis teknis terhadap kondisi manajemen stockpile. Data primer meliputi pola penimbunan, dimensi stockpile, dan kondisi operasional, sedangkan data sekunder berupa dokumen teknis dan data pendukung perusahaan. Hasil penelitian menunjukkan bahwa sistem pengelolaan stockpile di PT Lematang Coal Lestari belum sepenuhnya memenuhi standar KEPMEN ESDM No. 1827 K/30/MEM/2018. Tinggi timbunan mencapai 8 meter dengan sudut lereng 45°, melebihi standar yang direkomendasikan untuk batubara sub-bituminus. Selain itu, sistem FIFO belum diterapkan secara optimal sehingga meningkatkan potensi swabakar. Penelitian ini menyimpulkan bahwa diperlukan perbaikan pola penimbunan, geometri timbunan, penerapan FIFO, serta prosedur operasional untuk meminimalisir risiko swabakar dan meningkatkan efisiensi manajemen stockpile.
