Abstract

Riota Jaya Lestari Ltd. is a laterite nickel mining company located in North Kolaka Regency, Southeast Sulawesi, Indonesia, that implements quality control procedures to maintain the quality of its nickel ore production. This study aimed to evaluate ore quality at the mining face and stockpile, quantify changes in nickel (Ni) grade during material handling, identify the factors influencing grade variation, and assess their economic impact on the company. A quantitative approach, incorporating descriptive statistical analysis, was employed. Nickel assay data were processed using Microsoft Excel and presented in the form of tables and graphs illustrating grade distribution, grade deviation, and economic evaluation. PSI (grab sampling) was applied at the mining face, while truck sampling was conducted at the stockpile. The results showed that the average nickel grade at the mining face was 1.56% Ni, whereas the average grade at the stockpile increased slightly to 1.58% Ni, with an average grade deviation of 0.081%. Among the 35 paired samples analyzed, 23 samples exhibited an increase in nickel grade, 10 samples showed a decrease, and 2 samples remained unchanged. All analyzed samples contained nickel grades above the company's cut-off grade (COG) of 1.10% Ni, indicating that the ore remained economically viable for processing. Grade variation was primarily influenced by the heterogeneous nature of laterite nickel deposits, potential ore dilution during ore extraction, unplanned blending practices, differences in sampling methods, contamination during loading and hauling operations, and suboptimal sample preparation procedures. These findings indicate that comprehensive quality control should be implemented throughout the ore handling process to minimize grade variation from the mining face to the stockpile. Based on the observed grade changes, the company achieved an estimated additional profit of IDR 1,473,800,018.01, while grade reductions resulted in an estimated economic loss of IDR 637,889,152.05. Keywords: Laterite nickel, quality control, nickel grade, sampling, stockpile, grade control.

Abstract

Mold quality is one of the factors that determines dimensional accuracy, surface condition, and the success of metal casting. Gypsum is attractive for small-scale casting because it is easy to shape, relatively economical, and has adequate thermal resistance. This study evaluates the effect of water content and gypsum type on the mechanical and morphological characteristics of gypsum molds. Two gypsum types were used, namely fire-resistant gypsum (A) and gypsum board material (B), with water additions of 50, 60, and 70 ml for every 100 g of gypsum powder. Six specimens were produced, dried in an oven at approximately 200 °C for 60 minutes, and then tested by compression at a crosshead speed of 2 mm/min. Microstructural observations were carried out using optical microscopy at 400× and 1000× magnification. The highest compressive strength was obtained by specimen B3 at 2.06 MPa, followed by A3 at 2.05 MPa, while the lowest value was 1.95 MPa for A2 and B2. The B-series specimens also showed much lower strain than the A-series. Microscopic observations indicate that differences in particle distribution, agglomeration, and air voids contribute to the variation in mechanical response. The results provide a practical basis for selecting gypsum-water composition for small-scale casting molds.Keywords: gypsum, mechanical properties, morphology, mold, water ratio

Abstract

Fuel consumption by dump trucks is a major contributor to operating costs and emissions in open-pit mining. This study evaluates the change in hourly fuel consumption associated with implementing E2 Mode on Komatsu HD785-7 dump trucks assigned to haul routes dominated by loaded-downhill travel at a mining contractor in East Kalimantan, Indonesia. A quantitative before-and-after quasi-experimental design was used. The study included the entire population of 24 trucks through total sampling. The pre-implementation period covered Month 1–Month 3 under E3 Mode, whereas the post-implementation period covered Month 4–Month 12 under E2 Mode. One operating-mode average was calculated for each truck, producing 24 paired fuel-consumption observations. The paired differences were analyzed using the Shapiro–Wilk test and a two-tailed paired-samples t-test at a 5% significance level. Average fuel consumption decreased from 68.0 to 60.0 L/h, a reduction of 8.0 L/h or 11.76%, t(23) = −28.132, p 0.001, 95% CI [−8.588, −7.412]. Descriptively, productivity increased from 333 to 338 BCM/h, while cycle time changed only slightly from 18.302 to 18.403 min/cycle. Payload, haul distance, average speed, and average monthly operating hours per truck also remained broadly comparable. Because inferential tests were not available for these operational indicators and the study had unequal periods with no concurrent control group, the result should be interpreted as a strong association under the evaluated conditions rather than definitive causal evidence.Keywords: E2 Mode, fuel efficiency, Komatsu HD785-7, downhill haulage, mining dump truck.

Abstract

Penelitian ini dilaksanakan di Cv. Fajar Putih, Kabupaten Tuban, Provinsi Jawa Timur, pada kegiatan penambangan pasir silika dengan metode tambang terbuka. Penggunaan excavator sebagai alat gali–muat utama menjadikan konsumsi bahan bakar sebagai komponen biaya operasional yang perlu dikendalikan, namun perusahaan belum memiliki standar kuantitatif untuk mengevaluasi efisiensinya. Salah satu faktor yang diduga memengaruhi konsumsi bahan bakar adalah waktu edar (cycle time). Penelitian ini bertujuan menganalisis pengaruh cycle time terhadap fuel ratio sebagai indikator efisiensi bahan bakar excavator, sekaligus merumuskan upaya perbaikannya. Metode penelitian dilakukan melalui pengamatan langsung terhadap cycle time, produktivitas, dan konsumsi bahan bakar selama 13 hari, dianalisis menggunakan uji regresi linier sederhana. Hasil menunjukkan cycle time bervariasi antara 14,74–20,69 detik, dengan fuel ratio berkisar 0,07–0,17 liter/BCM (rata-rata 0,12 liter/BCM). Koefisien korelasi (r) sebesar 0,936 menunjukkan hubungan positif sangat kuat, sedangkan koefisien determinasi (R²) sebesar 0,876 berarti 87,6% variasi fuel ratio dipengaruhi oleh cycle time. Semakin lama cycle time, semakin tinggi fuel ratio sehingga efisiensi bahan bakar menurun. Upaya peningkatan efisiensi dirumuskan melalui tiga skenario: (1) pengurangan waktu gali (digging time) hingga nilai minimum, menurunkan fuel ratio menjadi 0,118 liter/BCM; (2) pengurangan waktu hambatan, meningkatkan efisiensi kerja menjadi 0,7508 dan menurunkan fuel ratio menjadi 0,116 liter/BCM; serta (3) kombinasi keduanya, yang memberikan hasil paling optimal dengan fuel ratio turun menjadi 0,113 liter/BCM. Selain itu, peningkatan keterampilan operator melalui teknik pemuatan yang tepat seperti pengaturan swing angle dan posisi alat terhadap front kerja turut mempercepat cycle time dan menurunkan fuel ratio. Upaya ini perlu didukung preventive maintenance berkala dan pemantauan konsumsi bahan bakar secara terstruktur. Hasil penelitian ini diharapkan dapat menjadi dasar dalam penetapan standar fuel ratio sebagai indikator evaluasi efisiensi operasional alat gali–muat.Kata kunci: Rasio bahan bakar; waktu edar, pasir silika.

Abstract

Implementing the International Safety Management (ISM) Code is crucial for enhancing maritime safety, particularly during cargo operations. This study analyses the implementation of the ISM Code using a Risk Assessment method to achieve zero accidents during cargo operations aboard the MV Spil Hayu. It employs a qualitative descriptive case study design. Data were gathered through direct onboard observations, crew interviews, and a review of safety management documentation. The risk analysis was conducted by identifying potential hazards, assessing risk levels, and determining appropriate control measures in accordance with ISM Code requirements. The findings indicate that although the MV Spil Hayu has generally implemented ISM Code practices, several potential risks remain inadequately managed. These include poor compliance with operational procedures, inconsistent use of personal protective equipment (PPE), and ineffective onboard communication. The application of a Risk Assessment method enabled the identification of risk priorities and the development of more systematic mitigation strategies, thereby effectively reducing workplace accident risks. The study concludes that consistently integrating the ISM Code with Risk Assessment practices is instrumental in achieving zero accidents during cargo operations. Consequently, realising this goal requires enhanced supervision, targeted crew training, and regular evaluation of the safety management system.

Abstract

This study investigates the effects of steel shot abrasive particle size and nozzle pressure on the surface characteristics and corrosion behavior of ASTM A36 steel subjected to dry abrasive blasting. Two steel shot sizes, S390 (1.2 mm) and S460 (1.4 mm), were employed, while nozzle pressures were varied at 6, 7, and 8 bar. The blasting results showed that all specimens achieved the Sa 2½ surface cleanliness standard, indicating effective removal of surface contaminants. Surface roughness measurements revealed that increasing both abrasive particle size and nozzle pressure generally resulted in a rougher surface. The highest average surface roughness was obtained using S460 steel shot at a nozzle pressure of 8 bar, reaching 104.44 ± 6.81 µm before corrosive immersion and increasing to 117.33 ± 0.54 µm after immersion. The corrosion behavior was subsequently evaluated using the weight loss method. Consistent with the surface roughness results, the highest average corrosion rate was also observed for specimens treated with S460 steel shot at 8 bar, reaching 88.83 ± 24.17 mpy. These findings demonstrate that variations in steel shot size and nozzle pressure significantly influence the surface condition of ASTM A36 steel and its subsequent corrosion performance, with larger abrasive particles and higher blasting pressures producing rougher surfaces that are associated with higher corrosion rates.
