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

Exploration is a crucial stage in mining activities, providing quantitative and qualitative information about the existence of mineral deposits. One direct exploration method used is core drilling, which involves retrieving subsurface rock samples (cores) for laboratory analysis. The results of these analyses serve as a fundamental database for resource estimation. One key parameter for evaluating the success of core drilling is the core recovery value, which is the ratio of the length of the core obtained to the total length drilled. This value reflects how well the core represents actual subsurface geological conditions. PT Pegasus Mineral Nusantara is currently conducting core drilling activities as part of a gold exploration project located in Paya Tampu Village, Rusip Antara District, Central Aceh Regency, Aceh Province. However, several issues have been encountered during core drilling, such as core loss due to falling back into the borehole and discrepancies in measured core lengths (gain/loss). This study aims to calculate and analyze core recovery using the Total Core recovery (TCR) method from drilling samples and identify the factors affecting core recovery success. The findings of this research are expected to contribute to improving the quality and reliability of mineral exploration drilling programs.

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

Pada PT Hutamas Koado masih terdapat beberapa beberapa jalan yang belum sesuai standar seperti, grade yang terlalu tinggi yaitu 13% melebihi batas maksimum yang ditetapkan perusahaan yaitu 8%, dan masih banyak lebar jalan yang belum sesuai aturan sehingga alat terjadi antrian ketika truck melintas secara bersamaan, sehingga menyebabkan cycle time dari alat angkut bertambah. Penelitian ini mengevaluasi kesesuaian geometri jalan tambang PT Hutamas Koado terhadap standar Kepmen ESDM 1827/K/30/MEM/2018. Hasilnya menunjukkan dari 100 segmen jalan (73 lurus, 27 belok), banyak yang tidak memenuhi kriteria ideal: (1) 19 segmen jalan lurus lebih sempit dari lebar ideal 13 m, (2) seluruh jalan belok tidak mencapai lebar teoritis 22 m, (3) 32 segmen memiliki cross slope tidak ideal (standar 13 cm), (4) hanya 1 segmen yang memenuhi superelevasi ideal 0,9 m, dan (5) 5 segmen melebihi kemiringan maksimum 10% (mencapai 13,146%). Temuan ini mengindikasikan ketidaksesuaian signifikan antara desain jalan tambang dengan standar yang berlaku.
