Abstract

The condenser plays an important role in cooling the steam coming out of the turbine and turning it into condensate water again. However, there are several factors that can influence the effectiveness of the condenser, such as the NTU (Number of Transfer Unit) value, vacuum pressure and cooling water temperature, so they can have a significant impact on condenser performance and the overall working efficiency of the PLTU. This research was carried out at the Tarahan Harbor 2x8 MW PLTU. The aim of this research was to determine the influence and correlation of the NTU (Number of Transfer Units), vacuum pressure, and inlet cooling water temperature on the effectiveness of the condenser at the PLTU. This research method is quantitative, the research technique uses interviews, observation and documentation. The analysis used in this research uses multiple linear analysis. The research results show that the NTU (Number of Transfer Units) value has little influence on condenser effectiveness with an R-squared value of 0.24. Where the higher the NTU (Number of Transfer Units) value, the lower the condenser's effectiveness. Apart from that, vacuum pressure affects the effectiveness of the condenser with an R-squared value of 0.74. The higher the vacuum pressure (the more negative it is), the effectiveness of the condenser will increase. Meanwhile, the cooling water inlet temperature has no effect on the effectiveness of the condenser with an R-squared value of 0.09 because there are several parameters or other factors that influence the effectiveness of the condenser, such as cooling water circulation, pipe cleanliness, and the cleanliness of the condenser itself.

Abstract

Salah satu komponen utama untuk menyuplai energi listrik ke Kereta Rel Listrik (KRL) rute Duri- Tangerang agar dapat beroperasi adalah gardu traksi. Dalam mengatur KRL ini PT. KCI menggunakan GAPEKA atau Grafik Perjalanan Kereta Api yang menjadi acuan dalam pengaturan perjalanan kereta. Dengan menggunakan metode kuantitatif maka penulis ingin mengetahui pengaruh GAPEKA terhadap pembebanan Gardu Traksi khususnya rute Duri-Tangerang. Setelah dianalisa dari pengaruh GAPEKA, maka nilai kapasitas daya yang dibutuhkan terbesar pada KRL rute Duri – Tangerang tahun 2024 adalah pada gardu traksi Kalideres dengan nilai sebesar 439,73 kW. Adapun kapasitas gardu traksi yang disediakan adalah sebesar 3835 kW, dapat dikatakan bahwa kapasitas daya yang dibutuhkan KRL rute Duri-Tangerang masih memenuhi.

Abstract

The COVID-19 pandemic has caused competition in the industrial sector to become increasingly fierce. So entrepreneurs in the induction sector must create new strategies to maximize company support facilities. One of the company's supporting facilities is a warehouse. Entrepreneurs can benefit from the proposed raw materials warehouse layout design by utilising the Class-Based Storage Method. This method facilitates the retrieval of raw materials and offers a streamlined process. This Method procedure comprises several stages: counting the number of pallets stored in a warehouse that is 191 pallets, determine the hallway and the dimensions of the warehouse, storage media with algorithms determine the depth of the line and allocate floor space with Larson algorithm. We receive a suggested design for the raw materials warehouse plan, including the storage area size of 148.32 m2, total distance moved out of the entire feedstock is 1727.65m with a total Material Handling costs for raw materials is Rp 600,289.

Abstract

Steam Gas Power Plant (PLTGU) is a power plant that uses gas as fuel and reuses exhaust gas from the gas turbine to heat the pipes in the HRSG (Heat Recovery Steam Generator) to produce steam and rotate the steam turbine. PLTGU XYZ is a Gas and Steam Power Plant which has 2,154 MW. One of the important components used in PLTGU is the high-pressure transfer pump. A high-pressure transfer pump is a pump that functions to move water from the low-pressure drum through the high pressure economizer to the high pressure drum, using an automatic system. The type of high-pressure transfer pump at PLTGU XYZ is Type MC100-300/9. To maintain the efficiency of the high-pressure transfer pump, components need to be maintained or replaced. high pressure transfer pump components have been replaced on the pump shaft using the reverse engineering method. Before reverse engineering the large pump shaft the efficiency was 66%, and after reverse engineering the large pump shaft the efficiency was 63%, so the comparison of pump efficiency before and after reverse engineering the pump shaft was 3%.
