Abstract

This paper discusses the potential of tin mining in the IUP Laut DU 1562 area in East Belitung Regency. However, this potential is difficult to realize due to regulatory constraints, especially after the Bangka Belitung Province ratified Regional Regulation Number 3/2020 regarding RZWP3K which does not include this area as a mining area, but a fishing zone. Therefore, an inclusive and sustainablity study is needed for the utilization of marine space to provide benefits for the country, local governments, society, and minimize environmental impacts. In this study, PT Timah TBK conducted data and information collection stages and analysis stages, including discussions with related stakeholders, direct observations in the field, and related official documents. The result of this study is the development of three development scenarios, namely inclusive tin mining, exclusive tin mining, and non-tin mining. These scenarios are then analyzed using the Promethee method to produce policy recommendations.

Abstract

PT X is a company engaged in the limestone mining sector and simultaneously serves as a cement supplier. The company plans to transition from a three-shift work schedule to a two-shift system. This decision is driven by the increasing costs associated with mining, safety concerns, and time losses due to equipment maintenance, following various evaluations conducted by the company's management. This research aims to analyze the requirements for loading and transportation equipment necessary to achieve an annual production target of 4,500,000 tons after the implementation of the two-shift work schedule. The research methodology employed is quantitative, encompassing the collection of both primary and secondary data, as well as an analysis of equipment productivity. The findings indicate that to maintain the production target, it is essential to replace the current loading equipment from the CAT 988B wheel loader to the CAT 990H wheel loader. Additionally, adjustments to the number of equipment are required, including two units of the CAT 990H wheel loader and seven units of the CAT 773 dump truck for Crusher 1, as well as two units of the CAT 992K wheel loader and eight units of the CAT 777D dump truck for Crusher 2. The production capacity of this equipment configuration reaches 4,575,457 tons per year, demonstrating that the production target can be optimally met despite the reduction in the number of work shifts.

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.
