Abstract

Post-mining due to mining activities will produce heavy metals in the form of acidic water and accumulate in the land. The poor quality of the land used by tin mining causes damage to the land ecosystem so that the land cannot be regrown by vegetation and the Pb (Lead) content in tin tailings is 6.29 ppm. The aim of this research is land restoration, namely carrying out revegetation using sunflower plants to absorb the heavy metal Pb with the concept of edutourism. The method used is a simulation of planting sunflowers on an ex-mining area of 1 Ha, with a planting distance of 1 m, the number of sunflower plants is 8540. The research results show that with the sunflower garden concept by planting 8540 sunflowers, the Pb level that can be absorbed by the plants is 2.8310 kg.

Abstract

PT XYZ had a method called the on book method to determine the amount of coal tonnage in the ROM stockpile.. This method used the initial stock from the survey calculation resut at the beginning of each month, the incoming coal to the stockpile used truck count method, and the outgoing coal from stockpile used weighbridge calculation. PT XYZ used the survey calculation results at the beginning of the next month rather than on book method result to determine the difference. The Coal tonnages based on survey result data on April 2 was 34.225,454 tons. Whereas, for the on-book calculation, the stock at March 2 was 38.409,083 tons, the coal in 2 March - 2 April was 71.154 tons, and the coal out of 2 March - 2 April was 67.994,52 tons, so the final stock obtained was 41.568,56 tons. The difference from those two methods comparison was 7.343,11 tons. This research discover the factors causing the differences between two methods i.e. incompatible vessel capacity on the truck counts tonnage calculation, disorganized stockpile patterns, declining ROM stockpile base conditions, spilled material, total station tools and weighbridges which had not been calibrated yet.

Abstract

Mine Acid Water is one of the impacts of the mining industry that must be handled seriously because it can cause environmental quality degradation. The factor for the formation of AAT is due to the presence of sulfide minerals in the rock. It is necessary to prevent the formation of AAT by identifying rocks that are Potential Acid Forming (PAF) and Non Acid Forming (NAF). Identification of an AAT is carried out by static test. The research method uses quantitative data in the form of rock sampling with full coring drilling and conducting static tests in the laboratory. The results of this study were M01 samples (white sandstone) with ANC values of 1.7 KgH2SO4 /ton, NAG pH 6.63, Total Sulfur <0.01%, pH of paste 7.22 and NAPP -1.4 KgH2SO4 /ton. The sample was M02 (sand) with ANC value of 1 KgH2SO4 /ton, NAG pH 6.63, Total Sulfur <0.01%, pH of paste 7.37 and NAPP -0.7 KgH2SO4 /ton. The sample was M03 (black sandstone) with ANC value of 1.4 KgH2SO4 /ton, NAG pH 4.41, Total Sulfur 0.06%, pasta pH 6.89 and NAPP 0.4 KgH2SO4 /ton. The geochemical identification of rocks at PT Menara Cipta Mulia has 2 samples, namely M01 (white sandstone) and M02 (sand) samples that are Non Acid Forming (NAF) and 1 sample, namely M03 (black sandstone) samples that are Potential Acid Forming (PAF).

Abstract

Indonesia merupakan negara penghasil timah terbesar nomor dua di dunia setelah China. Sebaran sabuk timah Indonesia membentang dari Semenanjung Malaysia, Riau, hingga ke Kepulauan Bangka Belitung. Namun, cadangan bijih timah darat yang semakin sedikit, mengakibatkan diperlukannya pemanfaatan timah low grade untuk tetap memenuhi kebutuhan timah. Salah satu sumber timah low grade yang memiliki peluang untuk diolah kembali adalah Sisa Hasil Pengolahan (SHP). Penelitian ini dilakukan untuk mengetahui karakteristik kandungan dalam Sisa Hasil Pengolahan PT Babel Utama Korpora lalu melakukan peningkatan kadar melalui pengolahan menggunakan metode gravity concentration dengan alat humprey spiral. Proses analisa kadar dilakukan dengan metode Grain Counting Analysis (GCA) dan X-ray Fluorescene (XRF). Variabel operasi humprey spiral yang digunakan adalah ukuran butir sebesar 30 mesh, 40 mesh, dan 80 mesh, serta variasi lebar diameter daun humprey spiral 60 cm dan 90 cm. Percobaan peningkatan mendapatkan hasil optimal pada kombinasi variabel ukruan butir 40 mesh dengan lebar diameter daun humprey spiral 60 cm sebesar 0,5% Sn dengan recovery sebesar 26,75%. Namun hasil ini menunjukkan pengolahan kembali tailing tidak ekonomis dikarenakan sangat jauh dari kadar yang diterima untuk proses peleburan yaitu 60% Sn.

Abstract

The sump in the mine is a vital element in mining operations, so special handling is required in this regard. This research discusses the implementation of an automatic Water Level Indicator (WLI) device in mining. This tool is designed to monitor, control, and report the water level in the sump in real-time using an Arduino that utilises an ultrasonic sensor connected to a microcontroller-based control system. The actual measurement of water level data obtained from the WLI enables more precise pump control, thus avoiding the condition of the pump working less optimally. In its application, this WLI will utilise a simple Arduino and several sensors in the analysis, as well as the use of a transmitter to send actual data that will be captured by the receiver. For the power supply, the tool in the field will use solar panels so that this WLI is expected to operate 24 hours in monitoring. The results of this research show that the application of automatic WLI will provide several benefits, including a 5-10% increase in pumping energy efficiency, reduced operational costs by optimising pump working hours, increased working hours of 1-2 hours per day, and obtaining more accurate and actual data. Even in some cases, such as rain in the field, the tool can still work for monitoring so that it can transmit actual data in the field, so it will be very efficient when applied in mining.

Abstract

Penerapan radius aman alat sebesar 300 m pada peledakan overburden yang dilakukan setiap hari meningkatkan frekuensi Internal Operasional Delay (IOD), yang berdampak negatif terhadap efisiensi operasional dan meningkatkan konsumsi bahan bakar alat saat melakukan perpindahan menuju radius aman. Analisis Flyrock dilakukan menggunakan batuan berukuran ≥10 cm, dengan pengambilan data menggunakan GPS dan pengamatan arah lemparan flyrock melalui video drone dan pengamatan visual. Estimasi jarak lintasan flyrock maksimum ditentukan berdasarkan metode Richard dan Moore (2005), dengan memperoleh konstanta (k) yang disesuaikan dengan karakteristik batuan di lokasi. Nilai prediksi flyrock paling mendekati nilai aktual terjadi pada cratering, dengan persen error terkecil 18,33% dan penyimpangan 12,65 m. Faktor utama yang mempengaruhi jarak lemparan flyrock aktual adalah stemming dengan nilai sebesar 81,50%. Penentuan pengurangan jarak evakuasi alat menjadi radius aman 200 m menggunakan teori exclusion zone oleh Richard dan Moore (2005) dan penentuan skala kedalaman menggunakan teori (SDOB), menghasilkan standar nilai variabel tinggi stemming minimal 3,3 m pada kedalaman 7,80 m.

Abstract

Rare Earth Elements (REEs) have become critical components in modern technology; however, global reliance on Chinese supply (>80%) and the scarcity of economic deposits necessitate the diversification of REE sources, including utilizing coal ash. This study examines the REE potential in coal parting as the primary source of coal combustion ash materials at PT Kuansing Inti Makmur (PT KIM), Bungo Regency, Jambi Province, which features multi-parting coal characteristics with a high ash content (14.36%). The methodology includes Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) analysis for REE quantification and petrographic analysis for mineralogical characterization. The results reveal that the total REE content in the parting reaches 180.01 ppm, dominated by Cerium (Ce) (65.68 ppm) and Neodymium (Nd) (38.91 ppm). Petrographic analysis identifies the REE-bearing host rock as siliciclastic sediment composed primarily of quartz and feldspar within a clay matrix. Based on a parting volume of 85,000 m3, the hypothetical resource estimation yields a total potential of 32.13 tonnes of REE, including Ce (11.7 tonnes) and Nd (6.9 tonnes). These findings indicate that the high-ash, multi-parting coal parting at PT KIM holds significant potential as an alternative REE source through the utilization of residual coal combustion ash. The presence of REE within the parting enables its accumulation and enrichment during the combustion process.

Abstract

Mining progress analysis was conducted by comparing the monthly plan with the results of the end-of-month survey. This study used a quantitative method, because it uses numbers in its analysis. The purpose of this study was to determine mining progress based on area, depth, and volume, compare survey progress, and analyze factors that influence the achievement of overburden production. Based on the comparison of the monthly plan and topography progress, the results of mining progress were obtained based on 100% area. Based on depth, different percentage achievements were obtained at each elevation ranging from 0% to 100%. And the achievement of mining progress based on volume was 52.20%. Factors that influenced the failure to achieve overburden production, both in terms of depth and volume, included: the use of equipment that did not comply with the plan so that the overburden fleet was not realized from the plan, high rainfall and reduced operating hours due to the month of Ramadan. Efforts that can be made to improve the achievement of overburden production include ensuring the suitability of the number and capacity of equipment according to the planned fleet, reducing bottlenecks, conducting routine equipment maintenance, and optimizing the drainage system so that mining activities continue to run during high rainfall.

Abstract

Belitung Island is one of Indonesia's largest tin production centers, where mining activities are dominated by community miners operating within PT Timah Tbk's Mining Business Permit area. This study aims to identify the actual conditions of community tin mining and analyze the implications of limited tin ore absorption by PT Timah Tbk on Local Original Revenue (PAD), community purchasing power, and socio-economic stability in Belitung. A qualitative method was employed through field observation, in-depth interviews with 42 respondents (37 community miners, 2 company partners, 3 policymakers), and documentation. Data analysis used descriptive and SWOT approaches. Results show that 73.8% of miners expect increased quotas because limited absorption causes income instability, payment delays, and encourages sales to middlemen. The study identifies four critical implications: (1) no significant increase in PAD; (2) widespread tin ore smuggling (estimated at 80%); (3) declining purchasing power and failure to achieve socio-economic welfare; and (4) the risk of a second wave of demonstrations after October 2025. Policy recommendations include accommodative absorption, strengthening partnerships through village cooperatives, and technology-based supervision.
