Abstract

The Priok PLTGU Block 4 Chlorination Plant had experienced component damage, which is the electrolysis generator B, to be precise in the 4th order electrolysis cell. One of these cells was damaged which caused the current and voltage used for the electrolysis process to become unstable and required handling of the incident. The handling step taken by the operator is to switch over to the electrolysis generator A which has a standby status. In this study the authors aim to create simulation conditions, and see the feasibility of performance if the electrolysis generator is still running using only 3 cells. The feasibility of the performance is assessed based on a comparison of the concentration of chlorine produced, then compared with the minimum requirement for the generating unit's water purification system, and calculating the available residual chlorine. The results of this study indicate that the concentration of chlorine resulting from the operation of the 3 cell mode is not much different from the normal 4 cell operation, and is able to meet the min-imum requirement of chlorine for the generator, as well as the residual which is classified as safe limits so that the 3 cell operating mode is classified as feasible to operate.

Abstract

Centrifugal pumps type Overhung 4 size 4x11 often experience sand deposits and erosion problems, especially in the oil and gas industry, resulting in reduced productivity and increased repair costs. This study evaluates the application of the Piping Plan 13 API 682 as a solution to this problem. The 5-Why Analysis method is used to identify the root cause of sand deposits, which were associated with sand contamination from a liquid source and the absence of an effective filtering system. The implementation of Piping Plan 13 aims to prevent sand deposits in critical areas, such as the Pedestal Cover and Pedestals, by leveraging the circulation design of the pipeline. The results showed a 19.75% increase in pump productivity and a 76.12% reduction in repair costs. Productivity increases reached 336,000 barrels (about 53,419,731 liters) over 16 days of operation, while the repair cost fell from Rp6,699,950 to Rp1,600,000. These findings indicate that Piping Plan 13 API 682 is an effective solution to increase the life and performance of the centrifugal pump and reduce maintenance costs in operating conditions with high sand contamination.

Abstract

The lack of soap production capacity, which currently only reaches 5-10 liters of soap per production, has prompted a team of lecturers at the Manufacturing Engineering Applied Masters Study Program (MTRTM)-PNJ to take the initiative to organize and donate a soap mixing machine. The purpose of this implementation is to increase the amount of community soap production, as well as increase community knowledge and skills regarding soapmaking processes and tools. The training was carried out by delivering material on how to use and tricks for making soap with a mixer machine, which was then continued by making soap by PKK women and ending with a survey of the training implementation. From the results of the training, it was found that soap production increased to 20 liters in one production run, as well as an increase in community knowledge and skills in the process of making soap with a mixer machine. Kurangnya kapasitas produksi sabun yang saat ini hanya mencapai 5-10 liter sabun satu kali produksi, membuat tim dosen di Program Studi Magister Terapan Rekayasa Manufaktur (MTRTM)-PNJ berinisiatif mengadakan dan menghibahkan mesin pengaduk sabun. Tujuan dari pelaksanaan ini adalah untuk meningkatkan jumlah produksi sabun masyarakat, serta meningkatkan pengetahuan dan keterampilan masyarakat terhadap proses dan alat pembuat sabun. Pelatihan dilakukan dengan penyampaian materi cara penggunaan dan trik pembuatan sabun dengan mesin pengaduk yang kemudian dilanjutkan dengan pembuatan sabun oleh para ibu ibu PKK, dan diakhiri dengan survey pelaksanaan pelatihan. Berdasarkan hasil pelatihan didapatkan peningkatan produksi sabun mencapai 20 liter dalam satu kali produksi, serta didapatkan pula peningkatan pengetahuan dan keterampilan masyarakat dalam proses pembuatan sabun dengan mesin pengaduk.
