Abstract

This study analyzes the thermal performance of a shell and tube type oil cooler installed in the generator of the KM Trans Mitramas 5 fishing vessel, located in Samudera Bitung Fishing Port, North Sulawesi. Using the Finite Element Analysis (FEA) method and ANSYS simulation, the study investigates how thermal loads, derived from different power levels (70 kW, 130 kW, and 200 kW), affect heat transfer effectiveness and temperature distribution. The results show increasing Log Mean Temperature Difference (LMTD) and hotspot patterns correlating with higher thermal loads. Simulation findings confirm the oil cooler’s capability to stabilize oil temperature under varying loads, with LMTD values of 38.12°C, 53.00°C, and 56.18°C respectively. The system remains efficient, though routine maintenance and proper material selection are recommended for long-term performance

Abstract

This research focuses on the viscosity and Total Base Number (TBN) of lubricating oil in diesel engines. The study tests the characteristics of new lubricating oil, oil used for 500 hours without and with CJC type fine filters, and oil used for 1336.5 hours with CJC fine filters. The testing follows the ASTM D445-21e2 and ASTM D2896-21 methods at the PT PETROLAB SERVICES Laboratory. The results reveal that using CJC fine filters can prolong the life of lubricating oil, as it preserves the quality, particularly within the first 500 working hours. However, beyond 1336.5 hours, some test results become unreasonable, indicating that the oil is no longer suitable for use. To gain a comprehensive understanding of the changes in lubricating oil quality, further testing at 750 and 1000 hours is suggested. Overall, this research highlights the importance of maintaining lubricating oil quality in diesel engines and the potential benefits of using CJC fine filters.

Abstract

Penelitian ini bertujuan untuk mengevaluasi kinerja heat exchanger (HE) pada mesin induk KM Madidihang 03 dengan menggunakan parameter suhu inlet dan outlet dari fluida pendingin. HE tipe plate and frame digunakan untuk menjaga suhu mesin tetap optimal selama operasional kapal. Pengukuran dilakukan pada perjalanan Jakarta-Benete dan sebaliknya, mencakup parameter Log Mean Temperature Difference (LMTD), laju perpindahan panas, dan koefisien perpindahan panas. Hasil menunjukkan efektivitas HE mencapai 74,3% dengan LMTD 15,66°C pada perjalanan Jakarta-Benete, sementara pada perjalanan pulang terjadi penurunan efektivitas menjadi 71,6% dengan LMTD 17,09°C akibat fouling. Penurunan ini menunjukkan perlunya perawatan preventif yang lebih optimal, termasuk pembersihan rutin dan penambahan komponen penyaring. Studi ini menegaskan pentingnya pemeliharaan HE untuk memastikan efisiensi operasional mesin kapal.
