Abstract

In doing slope design, paying attention to slope geometry and soil shear strength is necessary. Determination of slope geometry design also considers the balance between height and slope and production benefits. Research was conducted to analyze slope stability by testing physical and mechanical properties, limit equilibrium, and probabilistic Monte Carlo methods. The surface area of the Overburden stripping area in the 2024 RKP design amounted to 8,172.79 ????2. The production target is 2,000,000 tons of coal with a volume of overburdened material that must be stripped of 29.00, and a Stripping Ratio was obtained with a value of 14.5. The results of the overall slope evaluation of the Old Dump material with an overall slope height of 66.582 m, a slope width of 447.69 m, an overall slope of 8.32? and a bench width of 25 m, a bench height of 6 m with a ratio of 1:3 and a single slope angle of 18.43?. Then, the redesign was carried out and obtained recommendation results of 64.799 m overall slope height, 303.33 m slope width, 1,3.02? overall slope, and 25 m bench width, bench height at elevation 131-110 of 8 m with a comparison ratio of 1:2, single slope 26.57? and at elevation 110-50 of 8 m with a comparison ratio of 1:1.5, single slope 33.69.

Abstract

Coal mining activities in adjacent Mining Business Permit (IUP) areas often face technical challenges at pit boundaries. Conventional double-wall pit designs generally lead to pit losses at border zones, increased overburden volume, and higher stripping ratios, resulting in reduced mining efficiency and suboptimal utilization of coal reserves. Meanwhile, Indonesian mining regulations—Law No. 3 of 2020 in conjunction with Law No. 4 of 2025, Government Regulation No. 96 of 2021, and Ministerial Decree of Energy and Mineral Resources (Kepmen ESDM) No. 1827 K/30/MEM/2018—emphasize the obligation to conserve mineral and coal resources through efficient and optimal mine planning. This study aims to evaluate the planning of sharing wall (joint boundary slope mining) at IUP boundaries as a strategy for coal conservation and regulatory compliance. The research methods include analyzing existing double-wall designs, developing an alternative sharing wall model, recalculating overburden volume, coal reserves, stripping ratio, and pit loss potential, and assessing technical results against conservation regulations. The case study was conducted at the boundary of PT Merapi Energy Coal’s IUP in Lahat Regency, South Sumatra. The analysis results show that implementing the sharing wall design results in a 70 million bcm deviation in overburden volume, an increase in stripping ratio from 5.39 to 5.94 bcm/ton, and an additional 11.8 million tons of recovered reserves compared to the double-wall design. This strategy supports resource conservation principles as stipulated in Kepmen ESDM No. 1827 K/30/MEM/2018, particularly regarding pit loss reduction and coal recovery optimization. Therefore, sharing wall planning not only enhances technical and economic efficiency but also strengthens compliance with national mining conservation regulations.

Abstract

Oil palm is one of the main plantation commodities in the South Sumatra region. The high price of palm oil makes people try to open or replace their land into oil palm plantations. The failure of the people's oil palm nurseries is a very serious problem during the pandemic. However, in preparing the oil palm seeds, the community is considered a failure because the success rate for the nursery is below 50% or even only 20%. The community's ability to buy oil palm seeds also does not exist because the seeds sold in the market range from Rp. 23,000 to Rp. 45,000 per seed 6 months old. Therefore, assistance and development of early stage oil palm nurseries is carried out. It is hoped that this activity can help the community's difficulties in an effort to participate in the welfare of the local community. The method used is the delivery of material then followed by practice. This practice starts from preparing the planting medium, planting, care, and maintenance. The results obtained show that the failure of the nursery experienced by the community was caused by an inappropriate planting medium, namely the size of a polybag less than 30cm x 30 cm. Then there is no shade so that many seeds experience drought and die. Maintenance of seeds that are not given enough attention, such as watering and fertilizing. These three factors are the main problem of nursery failure. The results of the nursery carried out in this activity reached 98% of the total seeds planted.

Abstract

Proses penambangan timah menggunakan air sebagai media pemisah timah dari mineral lain. Air limbah hasil produksi disalurkan ke kolam penampungan, namun berpotensi mencemari lingkungan, terutama saat curah hujan tinggi atau setelah penambangan selesai. Kandungan tembaga (Cu) yang tinggi dalam air limbah dapat merusak insang, hati, ginjal, dan sistem saraf ikan, sehingga perlu dikaji tingkat risikonya. Penelitian ini bertujuan menghitung indeks risiko ekologi potensial tembaga (Cu) menggunakan data sekunder dari PT. Timah yang diolah dengan metode Hakanson. Pengujian sampel air dilakukan di Laboratorium Terpadu Institut Pertanian Bogor menggunakan metode APHA 23rd (2017): 3111 B. Hasil perhitungan berfungsi sebagai alat diagnosis pengendalian pencemaran, menentukan area prioritas penanganan, serta memahami ancaman aktivitas tambang timah terhadap ekosistem. Perhitungan ini diterapkan untuk sistem perairan limnik atau perairan tergenang. Indeks polusi dibandingkan dengan baku mutu air kelas II sesuai PP No. 22 Tahun 2021, yang digunakan untuk budidaya ikan air tawar. Berdasarkan hasil, indeks polusi air limbah tambang timah di Kepulauan Bangka termasuk kategori risiko rendah (RI<150), sehingga limbahnya masih tergolong aman bila terjadi luapan ke daratan.

Abstract

Penelitian ini membandingkan kualitas air laut di Dermaga Pantai Penganak, Kabupaten Bangka Barat, Kepulauan Bangka Belitung pada tahun 2023 dan 2024. Kajian ini dilakukan untuk mengetahui dampak aktivitas penambangan timah laut terhadap parameter fisika dan kimia air laut. Pengambilan sampel dilakukan di beberapa titik dengan parameter utama yang dianalisis meliputi TSS, pH, salinity, kadar amonia (NH₃-N) dan sulfida (H2S), kadar logam berat (Hg, Pb, Cd, Cu, dan Zn) serta beberapa parameter lainnya. Hasil penelitian menunjukkan adanya fluktuasi kualitas air antara kedua tahun tersebut, dengan peningkatan kadar logam berat di beberapa titik yang diduga berasal dari aktivitas pertambangan. Meskipun sebagian besar parameter masih berada dalam batas baku mutu yang ditetapkan, terdapat indikasi penurunan kualitas air laut yang perlu menjadi perhatian. Oleh karena itu, diperlukan pengelolaan lingkungan yang lebih ketat serta upaya mitigasi untuk mengurangi dampak pencemaran akibat aktivitas pertambangan di wilayah tersebut.

Abstract

This study analyzes the effectiveness of the coal supply chain as a key factor in maintaining production continuity and distribution stability in the mining industry. The research aims to evaluate the technical performance of the coal supply chain system at Pit TSBC of PT Bukit Asam Tbk, which integrates a shovel–truck system and a Bucket Wheel Excavator (BWE) system. The research methods include productivity analysis of loading and hauling equipment, cycle time evaluation, match factor calculation, availability assessment, and identification of potential system bottlenecks. The results indicate that the productivity of the shovel–truck system, at 3,075 tons per hour, remains below the effective capacity of the BWE system at 3,150 tons per hour, making the shovel–truck system the bottleneck of the supply chain. The average dump truck cycle time of 15.24 minutes produces 102.5 tons per hour per unit; however, an increase in hauling time to 20.82 minutes reduces productivity to 76.92 tons per hour per unit. Equipment availability, ranging from 80–90%, also significantly affects production continuity. Optimization of the match factor and improvement of hauling road infrastructure are identified as the primary recommendations to enhance overall supply chain performance.

Abstract

This study examines the influence of the implementation of the Mining Safety Management System (SMKP) on workplace accident rates within coal mining operations. A quantitative research design was adopted, utilizing survey data obtained from 390 employees working in mining companies operating under IUP PMDN in South Sumatra. The variables investigated consist of technical risk control, adherence to Standard Operating Procedures (SOP), safety training and emergency drills, and the utilization of Personal Protective Equipment (PPE). Data analysis was conducted using multiple linear regression to assess both the individual (partial) and combined (simultaneous) effects of the independent variables on accident rates. The findings indicate that the regression model is statistically significant, with a coefficient of determination (R²) of 0.436, suggesting that 43.6% of the variability in workplace accidents is explained by the variables included in the model. At the individual level, safety training and PPE utilization demonstrate a significant effect on accident rates, whereas technical risk control and SOP compliance do not exhibit a statistically significant influence. These results suggest that behavioral aspects have a more prominent role compared to system-related factors in mitigating workplace accidents. Accordingly, this study underscores the need to prioritize the enhancement of safety training programs, strengthen safety awareness, and ensure consistent PPE compliance as critical strategies for improving safety performance in the mining industry.

Abstract

Reklamasi lahan pascatambang batubara merupakan kewajiban perusahaan pertambangan dalam memulihkan fungsi ekologis lahan yang terdegradasi. Evaluasi keberhasilan reklamasi secara konvensional masih bersifat administratif dan belum mampu menggambarkan kualitas ekologis lahan secara menyeluruh. Penelitian ini bertujuan mengevaluasi keberhasilan reklamasi tambang batubara PT XYZ di Kabupaten Lahat, Sumatera Selatan, dengan mengintegrasikan analisis Normalized Difference Vegetation Index (NDVI) berbasis citra satelit Sentinel-2 dan pengukuran parameter kesuburan tanah secara laboratorium. Pendekatan kuantitatif deskriptif dengan analisis spasial digunakan pada area reklamasi periode 2017–2019. Sebanyak 31 titik sampel tanah diambil berdasarkan kelas vegetasi NDVI (rendah, sedang, tinggi) untuk diuji parameter pH, C-organik, N-total, P?O?, K?O, dan KTK. Hasil pemetaan NDVI periode 2021–2025 menunjukkan tren peningkatan signifikan pada kelas vegetasi tinggi dari 23,02% (2022) menjadi 54,51% (2025), mengindikasikan keberhasilan proses revegetasi secara spasial. Uji korelasi Pearson menunjukkan bahwa nitrogen (N) merupakan satu-satunya parameter yang berkorelasi positif signifikan dengan NDVI (r = 0,530; p = 0,002), sedangkan fosfor (r = ?0,360; p = 0,047) dan kalium (r = ?0,567; p = 0,001) berkorelasi negatif signifikan. Parameter pH, C-organik, KTK, Na, dan Ca tidak menunjukkan hubungan yang signifikan. Temuan ini menegaskan bahwa NDVI efektif memantau tutupan vegetasi secara spasial, namun tidak sepenuhnya merepresentasikan kualitas kimia tanah. Pendekatan integratif NDVI dan kesuburan tanah menghasilkan evaluasi reklamasi yang lebih komprehensif dan diagnostik dibandingkan penggunaan NDVI sebagai indikator tunggal.
