Abstract

Abstract. PT XYZ is a coal mining company that employs four mining stages in its operations: ripping, digging, loading, and hauling. The digging-loading equipment used is the Volvo 480D, and the hauling equipment is the Volvo FMX400. The hauling process significantly impacts the achievement of production targets. In January, the coal production from Pit 2 fleet 1 reached 93% of the production target. Several road geometry conditions can affect the speed of the hauling equipment, impacting the production targets. To address the issue of slowing hauling equipment, data such as the actual speed of the hauling equipment from each road segment, the weight of the hauling equipment, road geometry, and classification of resistance values are needed to determine the actual rimpull value. Reducing the rimpull value involves evaluating and improving the mining roads, considering factors such as road grade, cross slope, superelevation, and the surface material of the mining roads that affect the rolling resistance. Road grade changes were implemented in segments C-D and J-L. After evaluating and improving the roads, theoretically, the loaded travel time decreased to 3.1 minutes, and the empty travel time decreased to 1.8 minutes. Consequently, coal production increased from 91,826 BCM/month to 127,100 BCM/month, a production increase of 28.8%. Abstrak. PT XYZ adalah perusahaan pertambangan batubara yang dalam proses penambangannya meliputi empat tahapan: ripping, digging, loading, dan hauling. Alat gali-muat yang digunakan adalah Volvo 480D, sementara alat angkutnya adalah Volvo FMX400. Proses pengangkutan sangat mempengaruhi pencapaian target produksi. Pada bulan Januari, produksi batubara di Pit 2 fleet 1 mencapai 93% dari target produksi. Beberapa kondisi geometri jalan mempengaruhi kecepatan alat angkut saat hauling, yang berdampak pada pencapaian target produksi. Untuk mengatasi perlambatan laju alat angkut, diperlukan data seperti kecepatan alat angkut aktual dari setiap segmen jalan, berat alat angkut, geometri jalan, dan klasifikasi nilai ketahanan untuk mengetahui besaran nilai rimpull aktual. Pengurangan nilai rimpull dilakukan dengan mengevaluasi dan memperbaiki jalan tambang, baik dari geometri jalan seperti grade, cross slope, dan superelevasi, maupun dari material permukaan jalan tambang yang mempengaruhi nilai rolling resistance. Perubahan grade jalan dilakukan pada segmen C-D dan J-L. Setelah evaluasi dan perbaikan jalan, secara teoritis, waktu berangkat bermuatan menjadi 3,1 menit, sedangkan waktu berangkat kosong menjadi 1,8 menit. Produksi batubara pun meningkat dari 91.826 BCM/bulan menjadi 127.100 BCM/bulan, atau terjadi kenaikan produksi sebesar 28,8%.

Abstract

Abstrak. Untuk menerapkan Sistem Manajemen Keselamatan Pertambangan (SMKP) di PT Silva Andia Utama, evaluasi dilakukan menggunakan metode Analytic Hierarchy Process (AHP) untuk menentukan prioritas dan mengetahui efektivitas implementasi sistem. Berlokasi di Desa Giriasih, Batujajar, Kabupaten Bandung Barat, Jawa Barat, evaluasi ini melibatkan dokumentasi, kuesioner, audit SMKP, pembobotan AHP, serta analisis terhadap SOP dan Job Safety Analysis. Hasil evaluasi mengungkapkan adanya 2 risiko menengah dan 6 risiko sangat berbahaya yang memerlukan pengendalian lebih lanjut. Dari survei kepada 45 pekerja melalui 13 pertanyaan, sebagian besar responden menyatakan "setuju" bahwa SMKP diterapkan. Namun, audit SMKP hanya mencapai skor 4%, sementara pembobotan AHP menghasilkan nilai 194,64, dengan kategori predikat "Kurang" (D). Faktor utama kendala penerapan adalah rendahnya kesadaran pekerja terhadap penggunaan Alat Pelindung Diri (APD) dan ketidaksesuaian dengan SOP. Untuk perbaikan, direkomendasikan audit berkala untuk memantau dan membandingkan hasil implementasi SMKP dengan standar dalam Kepdirjen Minerba No. 185 Tahun 2019, serta evaluasi ketidaksesuaian dalam kegiatan kerja. Langkah ini penting untuk meningkatkan efektivitas sistem keselamatan kerja dan kesehatan di lingkungan pertambangan. Abstract. The implementation of the Mining Safety Management System (SMKP) at PT Silva Andia Utama in Giriasih Village, Batujajar District, West Bandung, was evaluated using the Analytic Hierarchy Process (AHP). The evaluation aimed to assess the system's effectiveness and identify shortcomings in occupational safety and health practices. Data sources included documentation, questionnaires, SMKP audits, and analyses of Standard Operating Procedures (SOPs) and Job Safety Analysis. The findings revealed 2 medium risks and 6 high risks, necessitating immediate risk control measures. A survey of 45 workers showed that most agreed SMKP was implemented; however, the SMKP audit scored only 4%, and the AHP assessment produced a score of 194.64, categorized as "Less" (D). These results indicated that SMKP implementation was not optimal. Key issues included low worker awareness of Personal Protective Equipment (PPE) usage and non-compliance with SOPs. These gaps underscore the importance of improving training and safety culture within the company. To enhance SMKP implementation, periodic audits should be conducted to monitor progress and compare results over time. Aligning practices with the Directorate General of Mineral and Mineral Resources Regulation No. 185 of 2019 is essential to ensure a safer and more compliant mining operation.

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.
