Abstract

The need and utilization of energy in society exceed available production. This condition requires acceleration and efforts to find solutions through the diversification of palm shell biomass into solid fuel briquettes. Palm shells have the potential as biomass and renewable energy sources that are selected based on strategic, technical, and environmental considerations. Its utilization so far has only been burned directly which causes air pollution or used as road paving in oil palm plantations. The environmental impact is the accumulation of solid waste, and global warming in the Crude Palm Oil processing industry. The research objective was to obtain the calorific value of palm kernel shell briquettes with carbonization process. The experimental research method carried out by innovating palm kernel shell briquette raw materials at various percentage variances (90%: 10%, 85%: 15%, 80%: 20%, 75%: 25%) using tapioca adhesive. The technical parameters of briquettes making are molding pressure of 10 MPa, particle grains of 60 mesh, carbonization temperature of 400oC; 450oC; 500oC with a holding time of 1 hour. From this study, the calorific value of palm kernel shell charcoal (PKSC) briquettes at a concentration of 85%;15% at a temperature of 400oC was 25.86 MJ/kg with tapioca adhesives as the highest calorific value parameters. The technology used to make palm kernel shell charcoal briquettes is a potential development that can be recommended as a precursor to solid fuels. The impact of developing PKSC biomass energy briquettes is an innovation in utilizing waste to create solid fuels. The implications of this research can be applied by home industries or households. This research is a contribution to solutions in overcoming energy needs and deficiencies as a form of sustainable energy..

Abstract

Mining activities are one of the activities that have high risks at every stage of their operational activities, so every potential hazard and risk that exists must be controlled to prevent accidents from occurring. This research aims to identify, assess, and control hazards and risks at every stage of mining activities at PT Golden Great Borneo. This research uses a semi-quantitative method, where hazard and risk assessment is carried out with a matrix of parameters of likelihood, exposure, and consequence. From the results of the research, the highest occupational safety risk in loading activities is that the distance between units is too close which can result in units crashing/nudging other units, the highest risk in hauling activities is thick dust so that visibility is less than 40 meters, and the highest risk in dumping activities is that the supervisor is in a blind spot area. Kegiatan penambangan merupakan salah satu kegiatan yang memiliki risiko tinggi pada setiap tahapan kegiatan operasional nya, sehingga setiap potensi bahaya dan risiko yang ada harus dikendalikan untuk mencegah terjadi nya kecelakaan. Penelitian ini bertujuan untuk melakukan identifikasi, penilaian, dan pengendalian bahaya dan risiko pada setiap tahapan kegiatan penambangan di PT. Golden Great Borneo. Penelitian ini menggunakan metode semi kuantitatif, dimana penilaian bahaya dan risiko dilakukan dengan matrik parameter tingkat kemungkinan, paparan, dan konsekuensi. Dari hasil penelitian risiko keselamatan kerja tertinggi pada kegiatan loading adalah jarak antar unit terlalu dekat yang dapat mengakibatkan unit menabrak/menyenggol unit lain, risiko tertinggi pada kegiatan hauling debu yang tebal sehingga jarak pandang kurang dari 40 meter, dan risiko tertinggi pada kegiatan dumping adalah pengawas berada pada area blind spot.

Abstract

PT Bumi Bara Makmur Mandiri is a mining company engaged in coal mining, located in Hajran Village, Bathin XXIV District, Batang Hari Regency, Jambi Province. The company employs an open-pit mining method, which results in the formation of depressions that act as rainwater catchment areas, creating pools (sumps). To manage these sump areas effectively for mining activities, a mine dewatering drainage system is implemented. Over the past ten years, rainfall data indicates a catchment area of 246.02 hectares, with an estimated rainfall of 280.88 mm for a return period of ten years. The groundwater that accumulates in the pooling area has an inflow rate of 0.11 m/s, leading to a total water discharge entering PIT A of 39.12 m/second. Currently, there is one pump available with a power capacity of 10.83 kW to remove this water. Due to the significant water discharge, it is essential to design an economical open flow that can handle a flow rate of 2.96 m/s. Furthermore, a design for a holding pond is required, as the existing capacity is insufficient to accommodate the incoming water discharge, which hampers the sedimentation process. To address this, a redesigned settling pond with dimensions of 46 m x 36 m x 7 m and six compartments has been proposed. This solution will enhance the effectiveness of the mine drainage process

Abstract

Kenagarian Jopang Manganti merupakan salah satu Nagari yang terletak di Kecamatan Mungka Kabupaten 50 Kota Sumatera Barat. Sekitar 10 tahun yang lalu aktivitas masyarakat kebanyakan bertani padi. Akan tetapi keadaan ini berubah semenjak harga cabe melonjak tinggi apalagi menjelang bulan puasa dan hari raya Idul Fitri. Banyak masyarakat yang mengubah sawah mereka menjadi ladang cabe. Terdapat puluhan KK yang menggeluti usaha ini dan menggantungkan hidup dari bertani cabe. Meningkatnya harga cabe di pasaran tidak sepenuhnya dirasakan efeknya oleh petani cabe. Keterbatasan akses dan informasi membuat petani cabe menjual hasil ladangnya biasanya ke toke dengan harga rendah. Apalagi hasil yang dijual masih dalam keadaan asli dari ladang. Padahal apabila cabe dilakukan pengolahan, akan menghasilkan produk yang memiliki nilai jual yang lebih tinggi. Dalam kegiatan pengabdian kepada masyarakat ini akan dilakukan upaya untuk meningkatkan nilai jual cabe dengan beberapa hasil produk olahan. Metode yang yang dilakukan dengan memberikan bimbingan teknologi, pendampingan, dan penguatan proses produksi seperti pengemasan dan proses penjualan. Hasil yang didapatkan berupa kepuasan masyarakat dalam pemahaman budidaya cabe secara menyeluruh dan meningkatnya produksi cabe yang bisa dihasilkan mencapai 40 kg dalam satu jam.

Abstract

Overburden stripping production at PT Paramitha Persada Tama, a nickel mining company in North Konawe Regency, particularly in Pit Block C and A1B, has not reached the target of 90,000 Bcm/month, as actual production using the existing excavation–loading configuration (Excavator JCB 205, Excavator JCB 305, Excavator Sumitomo 210) and hauling equipment (Hino 500 dump trucks) was only 62,712.4 Bcm/month in September 2021. This study aimed to analyze efforts to achieve the production target by changing the overburden stripping system from sidecast to a hauling system. A comparative approach was used by examining production performance, fuel consumption, and stripping costs between the sidecast system in September 2021 and the hauling system in November 2021. Cost evaluation was conducted by calculating operator salaries and fuel consumption expenditures based on a fuel price of Rp 7,850.00/liter. The analysis showed that under the sidecast system, fuel consumption reached 51,650 liters/month with a fuel ratio of 0.8 and total expenditure of Rp 513,301,500.00, whereas the implementation of the hauling system resulted in an actual production of 97,947.41 Bcm/month with fuel consumption of 47,782 liters/month, yielding a saving of 3,868 liters/month while simultaneously achieving the production target. These findings confirm that the hauling system is more effective and efficient than the sidecast system for overburden stripping at the study site and is feasible to adopt as an operational strategy to optimize production.

Abstract

Coal quality and classification was essential, as coal served as an alternative energy resource for industry. Prior to utilization, coal quality and classification were analyzed through laboratory testing. One method that was applied was the proximate analysis based on ASTM D388 standards. This study used coal samples collected from three coordinate points at CV. Bara Mitra Kencana. The test results indicated variations in coal quality. Coal from this location was utilized as fuel for the Ombilin Steam Power Plant (PLTU), with a blending process carried out beforehand to improve the economic value of lower-quality coal. The coal quality received by PLTU Ombilin was recorded at 17.00%, with a significant improvement observed after blending. Based on laboratory analysis, the coal was classified as bituminous—high volatile A, which was generally caking in nature. The calorific value obtained was 14,316 Btu/lb for sample I, and 14,062 Btu/lb for samples II and III. These results demonstrated that the calorific value of coal from CV. Bara Mitra Kencana exceeded 14,000 Btu/lb, thereby meeting the quality standards required for power plant operations.

Abstract

One important aspect of open pit mine planning is slope geometry design, which affects the stability of the slope and the efficiency of overburden removal. This study aims to investigate the influence of vertical bench position and bench width on slope stability and their effect on stripping volume. The limit equilibrium method was used for slope stability analysis, with the assistance of Rocscience Slide2 software. The stripping volume estimate was obtained from pit shell simulations using GEOVIA Surpac software. The vertical bench positions analyzed were ¼, ½, and ¾ of the total slope height, which was 60 m. The bench width variations tested were 0, 5, 10, 15, 20, and 25 m, while maintaining a minimum safety factor requirement of 1,3. The analysis indicated that the optimal configuration is achieved by placing the bench at the vertical position of ½ of the overall slope height with a bench width of 10 m, which results in an overall slope angle of 44°. The result is steeper than the no-bench scenario, with an overall slope angle of 42°. This geometry produces an estimated overburden volume of 195,123,000 m3, which is smaller than the no-bench scenario of 196,559,500 m3. Therefore, the reduction in stripping volume is 1,436,500 m3 or approximately 0.73%. This study shows that optimizing the bench configuration enables the implementation of steeper overall slope angles while reducing the required stripping volume in open pit mine planning.

Abstract

Penambangan terbuka di Pit South PT Anugerah Covindo Indonesia sangat dipengaruhi oleh curah hujan tinggi yang menyebabkan akumulasi air limpasan dan air tanah. Sistem penyaliran eksisting menggunakan sump dan pompa Deflow 6D14 belum mampu menangani debit air masuk secara optimal. Penelitian ini mengevaluasi efektivitas sistem penyaliran dengan metode analisis hidrologi menggunakan data curah hujan 2015–2024, metode rasional termodifikasi, serta evaluasi head dan daya pompa. Hasil menunjukkan debit air masuk sebesar 154.789,45 m³/jam, sedangkan kapasitas pompa hanya 1.240 m³/hari, menyebabkan genangan harian hingga 3,71 juta m³. Volume kolam pengendapan juga tidak mencukupi saat hujan ekstrem. Diperlukan penambahan pompa berkinerja tinggi dan perbaikan dimensi sump serta kolam pengendapan. Temuan ini penting untuk menjamin kontinuitas operasi tambang dan mencegah gangguan produksi akibat genangan.
