Abstract

Abstract. PT Long Daliq Primacoal is a coal mining contractor operating at PT Banjarsari Asli's IUP, located in East Merapi District, Lahat Regency, South Sumatra Province. This research was conducted because the mining operational costs did not meet the company’s established cost standards. Therefore, evaluating and controlling mining costs is necessary to meet these standards. The research used a comparative method by comparing planned data with actual data from the field. Both primary and secondary data were collected. Then, data processing and analysis were carried out to determine whether the operational costs aligned with the set standards. The results showed that in May, the planned production target of 275,000.00 BCM did not match the actual production of 217,134.00 BCM, resulting in a shortfall of 50,243.00 BCM. The planned mining operational cost was IDR 7,876,914,668.00, while the actual cost was IDR 7,387,765,786.00. The projected profit was IDR 2,629,071,161.78, but the actual profit was IDR 885,319,814.00, a difference of IDR 1,743,751,347.78. After implementing improvements, the production target increased to 284,408.43 BCM, operational costs were IDR 8,026,378,386.18, and profits reached IDR 2,809,582,719.03. Abstrak. PT Long Daliq Primacoal merupakan kontraktor tambang batubara di IUP PT Banjarsari Pribumi yang berada di Kecamatan Merapi Timur, Kabupaten Lahat, Provinsi Sumatera Selatan. Penelitian ini dilakukan karena tidak tercapainya biaya operasional penambangan dengan standar biaya yang telah ditetapkan perusahaan.  Maka dari itu dibutuhkan evaluasi serta control cost pada kegiatan penambangan untuk mencapai standar biaya yang telah ditetapkan perusahaan. Penelitian yang dilakukan ini menggunakan metode komparatif berdasarkan perbandingan data yang telah direncanakan sebelumnya dengan data aktual yang terjadi di lapangan. Data yang diambil yaitu data primer dan data sekunder. Lalu, dilakukan pengolahan data dan analisis berdasarkan rencana-aktual di lapangan, dan diketahui tercapai atau tidak biaya operasional penambangan dengan standar biaya yang ditetapkan perusahaan. Hasil dari penelitian yang telah dilakukan yaitu pada bulan Mei didapatkan target produksi yang telah direncanakan tidak sesuai dengan aktual lapangan, yaitu target produksi rencana sebesar 275.000,00 BCM dan aktual sebesar 217.134,00 BCM, dengan selisih 50.243,00 BCM. Dan juga, biaya operasional penambangan rencana sebesar Rp 7.876.914,668,00 dan aktual sebesar Rp 7.387.765.786,00. Total profit rencana sebesar Rp 2.629.071.161,78 dan aktual sebesar Rp 885.319.814,00 dengan selisih Rp 1.743.751.347,78. Setelah dilakukan perbaikan, didapatkan target produksi sebesar 284.408,43 BCM, biaya operasional penambangan sebesar Rp 8.026.378.386,18 dan profit sebesar Rp 2.809.582.719,03.

Abstract

Geoelectricity is a method in geophysics that studies the nature of electric currents in the earth and how to detect them on the earth's surface. This detection includes measuring potential, current and electromagnetic differences that occur naturally or as a result of injecting current into the earth (Kanata, and Zubaidah., 2008). Azhar and Handayani (2004) have carried out laboratory scale modeling to measure the resistivity of several coal samples from the Air Laya Mine using the Wenner-Schlumberger configuration, with the rationale that the resistivity method has been widely used for various shallow seam exploration purposes. The resistivity method is a geophysical method used to measure the apparent resistivity of a medium. Measurements with the Schlumberger configuration use 4 electrodes, 2 current electrodes and 2 potential electrodes each. From the results of measuring the current and potential difference for each particular electrode distance, variations in the resistance value of each layer below the measuring point (sounding point) can be determined. Based on 1D Geoelectric activities in the investigation area, several conclusions were obtained, as follows. Based on the results of geological mapping in the investigation area, it was found that the rocks scattered in the investigation area were in the form of Volcanic Breccia and Tufa Breccia. Based on the results of field observations, it was found that the physical properties of hot water in the investigation area had a TDS value of 250 ppm, then had a temperature of 54° Celsius and an electrical conductivity of 983 μS/m. Based on the results of the 1D Geoelectric investigation, it was found that there are several interpreted lithologies, namely Top Soil which is at an average depth ranging from 0 meters to 6,598 meters with an average resistivity value of 27.18 ohms, then next is the Volcanic Breccia lithology which is at The average depth ranges from 6,598 meters to 11,461 meters with an average resistivity value of 4.28 ohms, then next is the lithological indication of Tufa Breccia which is at an average depth ranging from 11,561 meters to 18,683 meters with an average resistivity value of 9 .44 ohm and then the lithological indication in the form of sandstone which is at an average depth ranging from 18.683 meters to 27.566 meters with an average resistivity value of 15.83 ohm and an indication of marl lithology at a depth of 27.566 meters to 39.55 meters with a resistance value type of 21.08.

Abstract

Abstract. This study aims to evaluate the actual capacity of Settling Pond CP1 based on runoff discharge and sedimentation, determine the optimal maintenance interval, and assess the effectiveness of Total Suspended Solids (TSS) reduction at the Bakan Site of PT J Resources Bolaang Mongondow. Hydrological analysis was conducted using the Rational Method based on rainfall data from 2015–2024, while the sedimentation rate was calculated from the combination of flow discharge and TSS concentration. The actual capacity of the settling pond was determined through topographic measurements and storage volume calculations. The results indicate that the actual capacity of Settling Pond CP1 is 178,109 m³, which is still sufficient to accommodate the design runoff discharge, although its capacity has decreased due to sediment accumulation. The total sedimentation rate entering the system is 27,003.2 m³/month, resulting in maintenance intervals of 1.88 months for Pond 1, 8.09 months for Pond 2, 4.00 months for Pond 3, and 12.97 months for Pond 4. TSS testing showed a reduction from 17,500 mg/L at the inlet to 30 mg/L at the outlet, with a removal efficiency of 99.7%, meeting the mining wastewater quality standard of 200 mg/L. Therefore, Settling Pond CP1 remains effective as a sediment control facility but requires periodic dredging according to the calculated maintenance intervals.   Abstrak. Penelitian ini bertujuan untuk mengevaluasi kapasitas aktual Settling Pond CP1 berdasarkan debit limpasan dan sedimentasi, menentukan interval pemeliharaan yang optimal, serta mengevaluasi efektivitas penurunan Total Suspended Solids (TSS) di Site Bakan PT J Resources Bolaang Mongondow. Analisis hidrologi dilakukan menggunakan Metode Rasional berdasarkan data curah hujan periode 2015–2024, sedangkan laju sedimentasi dihitung berdasarkan kombinasi debit aliran dan konsentrasi TSS. Kapasitas aktual settling pond ditentukan melalui pengukuran topografi dan perhitungan volume tampungan. Hasil penelitian menunjukkan bahwa kapasitas aktual Settling Pond CP1 sebesar 178.109 m³ masih mampu menampung debit limpasan rencana, meskipun telah mengalami penurunan kapasitas akibat akumulasi sedimen. Total laju sedimentasi yang masuk ke sistem sebesar 27.003,2 m³/bulan, dengan interval pemeliharaan masing-masing 1,88 bulan untuk Pond 1, 8,09 bulan untuk Pond 2, 4,00 bulan untuk Pond 3, dan 12,97 bulan untuk Pond 4. Pengujian TSS menunjukkan penurunan konsentrasi dari 17.500 mg/L pada inlet menjadi 30 mg/L pada outlet dengan efektivitas penurunan sebesar 99,7%, sehingga memenuhi baku mutu air limbah pertambangan sebesar 200 mg/L. Dengan demikian, Settling Pond CP1 masih efektif sebagai fasilitas pengendalian sedimen, namun memerlukan pengerukan sedimen secara berkala sesuai interval pemeliharaan yang telah ditentukan.

Abstract

Abstract. Blasting activities are conducted to break rock or to separate mineral deposits from the host rock through chemical means using explosives. One of the negative impacts of blasting is ground vibration, which can influence slope stability. Therefore, this study aims to evaluate and analyze the effects of ground vibration on slope stability based on PPV (mm/s), PPA (g), and Amaks (g). This research employed two analytical methods: the non-linear power trendline method and Multiple Linear Regression. Both methods were used to predict vibration levels using distance and explosive charge per delay as variables. Ground vibration measurements were conducted at 31 points with varying distances. The analysis refers to the company's allowable vibration threshold, which is 0.06 g. Vibration analysis was carried out by examining the relationship between PPA and PPV with SD to determine the maximum explosive charge per delay that can be safely used. The results show that the vibration levels remain within safe limits, as the highest recorded PPA was 0.15 g, below the threshold of 0.06 g. The charge that can be used in each blasting with a distance of at least 300 m with an explosive content of more than 50 kg/delay will produce a value that exceeds the limit. Abstrak. Kegiatan peledakan merupakan kegiatan yang dilakukan untuk memberaikan batuan atau memisahkan bahan galian dari batuan induknya dengan cara kimiawi menggunakan bahan peledak. Salah satu dampak negatif dari peledakan adalah getaran tanah.Getaran tanah akan mempengaruhi kestabilan. Oleh karena itu adanya penelitian ini untuk mengetahui dan menganalisis pengaruh getaran tanah terhadap kestabilan lereng berdasarkan nilai PPA (mm/s),PPV (g), dan Amaks (g). Kajian analisis pada penelitian ini menggunakan metode analisis non linier (Tredline Power) dan metode Multipe Linier Regression. Pada kedua metode yang digunakan yaitu untuk mengetahui prediksi dari nilai getaran dengan parameter jarak dan bahan peledak per waktu tunda. Pengukuran tingkat getaran peledakan dilakukan sebanyak 31 titik dengan jarak yang bervariasi. Analisis dilakukan berdasarkan trial and eror dengan tingkat getaran maksimum adalah 0,06 g. Analisis getaran dilakukan berdasarkan pada hubungan (PPA) dan (PPV) terhadap SD untuk mendapatkan muatan bahan peledak maksimum per waktu tunda yang digunakan. Hasil penelitian menunjukkan bahwa tingkat getaran terdapat nilai yang melebihi getaran maksimum nilai PPA tertinggi sebesar 0,15 g dan nilai ambang batas PPA sebesar 0,06 g. Muatan yang dapat digunakan pada setiap peledakan dengan jarak paling dekat 300 m dengan isian bahan peledak lebih dari 50 kg/delay akan menghasilkan nilai yang melebihi batas.

Abstract

Abstract. Open-pit sand and gravel mining operations are vulnerable to water accumulation from rainfall and surface runoff, which can disrupt mining activities. Therefore, an effective mine drainage system is required. This study aims to determine rainfall intensity, catchment area, runoff discharge, and to design drainage ditches and a settling pond. The research applies the E.J. Gumbel frequency distribution, Mononobe, and Rational methods to analyze rainfall and runoff. The study uses rainfall data from 2015–2024, topographic maps, land cover maps, and slope gradient maps.The results show rainfall intensities of 29.7 mm/hour for the catchment area outside the Mining Business License (IUP) and 27.7 mm/hour inside the IUP, with a design rainfall of 19.968 mm. The outside catchment covers 5.62 ha with a runoff discharge of 1,076 m³/hour, while the inside catchment covers 4.94 ha with a runoff discharge of 817 m³/hour. The proposed drainage system consists of seven ditch segments and a rectangular settling pond measuring 37.43 m × 24.95 m × 5 m, with a volume of 4,670 m³. The recommended dredging interval is 7.9 months.   Abstrak. Penambangan sirtu dengan metode tambang terbuka memiliki potensi terjadinya genangan dikarenakan air hujan dan air limpasan yang masuk ke area penambangan.

Abstract

Abstract. PT Bina Sarana Sukses (BSS), a coal mining contractor partnering with PT Manoor Bulatn Lestari, set an overburden production target of 4,800,000 BCM in July 2025, increased from 4,200,000 BCM in June 2025. To achieve this target, the company operated a two-shift system with 17 effective working hours per day. However, the change shift process caused production delays because the shift exchange point in the manpower area was located far from the operational pit. This study aimed to reduce delay time and improve production by implementing a Hot Seat Change Shift (HSCS) system at a new change shift location. The change shift process included traveling from the mess to the Transfer of Shift (TOS) area, fingerprint attendance, a five-minute safety briefing (P5M), waiting for the assigned unit, conducting a pre-start inspection (P2H), and operating the unit after safety confirmation. Before HSCS implementation, the average distance from the manpower area to the East Front was 2.20 km, requiring approximately 8.5 minutes for shift change. After implementation, the distance decreased to 1.79 km, reducing the change shift duration to 4.4 minutes. Monthly production improved from a loss of 30,174.26 BCM before implementation to a gain of 17,391.77 BCM, demonstrating that HSCS effectively minimized delays and enhanced operational productivity.   Abstrak. PT Bina Sarana Sukses (BSS) merupakan kontraktor pertambangan batubara yang bekerja sama dengan PT Manoor Bulatn Lestari. Pada Juli 2025, perusahaan menetapkan target produksi overburden sebesar 4.800.000 BCM, meningkat dari 4.200.000 BCM pada Juni 2025. Untuk mencapai target tersebut, perusahaan menerapkan sistem kerja dua shift dengan waktu kerja efektif 17 jam per hari. Namun, aktivitas pergantian shift menjadi salah satu penyebab keterlambatan produksi karena lokasi pergantian operator di area manpower berjarak cukup jauh dari area pit. Penelitian ini bertujuan mengurangi waktu keterlambatan dan meningkatkan produktivitas melalui penerapan sistem Hot Seat Change Shift (HSCS) pada lokasi pergantian shift yang baru. Aktivitas pergantian shift meliputi perjalanan dari mess menuju area Transfer of Shift (TOS), absensi sidik jari, pelaksanaan P5M, menunggu unit, pemeriksaan awal kendaraan (P2H), dan pengoperasian unit setelah dinyatakan aman. Sebelum penerapan HSCS, rata-rata jarak dari area manpower ke East Front mencapai 2,20 km dengan waktu pergantian shift sekitar 8,5 menit. Setelah penerapan HSCS, jarak berkurang menjadi 1,79 km dan waktu pergantian shift menjadi sekitar 4,4 menit. Produksi bulanan meningkat dari kehilangan 30.174,26 BCM menjadi tambahan produksi sebesar 17.391,77 BCM, sehingga HSCS terbukti efektif mengurangi keterlambatan dan meningkatkan produktivitas operasi.
