Risk Assessment at the Plate Production Unit (PPL) of PT. INKA (Persero)

Introduction: The plate manufacturing production unit is one of the work units in PT. INKA (Persero), which involves the interaction between humans and machines in its activities, heavy equipment, and materials, all of which can cause possible hazard impacts that can impact the safety and health of workers. The purpose of this study is to conduct risk assessment on occupational safety and health aspects by identifying risks, assessing risks, identifying control efforts and assessing residual risk as a form of efforts to prevent occupational accidents and occupational diseases, using existing resources effectively and efficiently. Method: This research is a type of qualitative research, through interviews and observations, with cross-sectional studies and descriptive analysis. The interviewees for this study were K3LH management managers, steel managers, and machine operators in the plate production unit (PPL). The tools in this study werean interview guide, Job Safety Analysis (JSA) and Hazard Identification Risk Assessment Determining Control (HIRADC) using the AS / NZS 4360: 2004 Risk Management Worksheet Standard Risk Matrix. Results: From the research, it was found that there are 94 hazards for 11 different machines. Regarding the risk levels, there are 9 extreme risk levels, 46 high risk levels, 33 medium risk levels and 6 low risk levels. Conclusion: There are still 61 risks with medium risk level and 6 remaining risks with high risk level that still need control. Control efforts have been implemented by PT. INKA (Persero) in accordance with the hierarchy of control, such as the use of PPE and the provision of work SOPs. Keywords: hazard identification, risk management, risk assessment, risk control, residual risk

Estudio de costos e ingresos en el Ejido Los Llanos, Arteaga, Coahuila; Elcaso de una unidad de producción lechera familiar / Costs and income study in the Los Llanos Ejido, Arteaga, Coahuila; The case of a family dairy production unit

La presente investigación se realizó con el fin de mostrar cómo se encuentra la situación económica del pequeño productor; él manifestó que no lleva un control sobre los gastos en los que incurre y de los ingresos que percibe; entonces si él tiene control sobre los gastos e ingresos podrá saber por ejemplo en qué gastos innecesarios incurre, de tal manera que tendrá una visión clara de la forma en que puede reducir sus costos y mejorar sus ingresos, que le permita mejorar su sistema de producción, con más eficiencia y eficacia de su negocio, dando como resultado una correcta toma de decisiones, es por eso que se realizó el estudio obteniendo un resultado positivo.

The role of farmer groups in the development of dryland farming in Ketos Village, Paranggupito Subdistrict, Wonogiri Regency

Farmer groups are play an important role in solving the farmers’ problems, especially about their farming activities. This study aims to find out the role of farmer groups in the development of dry land farming in Ketos Village using qualitative descriptive methods. The results showed that Ketos Village farmer groups conducted activities such as farmer deliberation, farmers group gathering, agricultural counselling, and gotong-royong. Based on these activities, Ketos Village farmer group is able to act as a learning class, production unit, and cooperation. Farmer group as a learning class is a farmer group as place that provides information needed by its members related to the issue of farming activities. Farmer group as a production unit means that farmer groups play a role in the provision of agricultural facilities and tools, especially subsidized seeds, and fertilizers. Farmer groups as a medium of cooperation is not only between internal groups but also for external. Then this role is able to help farmers’ activities in solving problems in dry land.

Rekayasa Nilai Kriteria Desain Fasilitas Produksi Gas Alam

Natural gas is one of the primary hydrocarbon energies in Indonesia. The construction of natural gas production facilities is essential to accommodate domestic energy needs. These facilities include production, pipelines, and processing facilities in an integrated manner. This study used the hydrocarbon composition of Field-X with an average of 7.62% CO2 and 0.06% H2S. The alternative design uses a fixed platform (fixed platform), MOPU (Mobile Offshore Production Unit), and a Semi-Submersible platform. The design comparison criteria are capital expenditure (CapEx), net present value (NPV), internal rate of return (IRR), work completion time, safety risk, and flexibility of future facility development. Through the comparison method, it is found that Option A is the best option, which has a design criterion value of 57%, a higher NPV of $43,537,469.58 than the smallest NPV option, an IRR of 19%, and a payout time (POT) of 5 years. Option A uses a fixed platform with a pipeline to the north, the hydrocarbon separation process is carried out on an offshore platform, and the processing is carried out onshore. ABSTRAKGas alam merupakan salah satu energi hidrokarbon utama di Indonesia. Pembangunan fasilitas produksinya sangat penting untuk mengakomodasi kebutuhan energi dalam negeri. Fasilitas ini meliputi produksi, jalur pemipaan, dan fasilitas pengolahan hidrokarbon secara terintegrasi. Penelitian ini menggunakan komposisi hidrokarbon dari Lapangan-X dengan rata-rata CO2 7.62% dan H2S 0.06%. Alternatif desain menggunakan anjungan tetap (fix platform), MOPU (Mobile Offshore Production Unit), dan anjungan Semi-Submersible. Kriteria perbandingan desain adalah modal awal, nilai bersih saat ini (NPV), tingkat pengembalian internal (IRR), waktu penyelesaian pekerjaan, resiko keselamatan, dan flexibilitas pengembangan fasilitas kedepan. Melalui metode perbandingan yang dipadankan didapatkan Opsi A adalah opsi terbaik, yang memiliki nilai kriteria desain 57%, NPV lebih tinggi $43,537,469.58 dibanding opsi NPV terkecil, IRR 19% dan waktu pembayaran (payout time/POT) 5 tahun. Opsi A menggunakan anjungan tetap dengan jalur pemipaan ke arah Utara, proses separasi hidrokarbon dilakukan pada anjungan lepas pantai (offshore) dan pengolahannya dilakukan di darat (onshore).
