Abstract

Permasalahan dalam negara maritim yang sering terjadi dalam dunia perkapalan dan sering mendapat perhatian adalah masalah pencemaran. Sumber-sumber pencemaran laut disebabkan di antaranya adalah aktivitas perkapalan. Salah satu upaya untuk mengendalikan pencemaran adalah dengan membakar sampah menggunakan insinerator. Pada penelitian ini, dikembangkan insinerator dengan sistem pengendalian dan kontrol untuk memenuhi batas-batas emisi partikel dan gas buang sehingga hasil sampah yang dibakar menjadi lebih ramah lingkungan. Tujuan penelitian ini adalah membuat rancang bangun insinerator sebagai alat peraga dalam proses pembelajaran, sehingga taruna memperoleh pemahaman mengenai salah satu permesinan bantu di kapal, yaitu insinerator sebelum melaksanakan praktek layar. Metode yang digunakan pada penelitian ini adalah Research and Development, yaitu proses atau langkah-langkah untuk mengembangkan suatu produk baru atau menyempurnakan produk yang sudah ada, baik itu perangkat keras maupun perangkat lunak. Pembuatan alat peraga ini memanfaatkan dua sistem yang saling terhubung yaitu sistem burner dan modul Arduino sebagai alat kontrol. Hasil penelitian menunjukkan komponen insinerator sesuai dengan rencana bangun atau desain awal, yaitu ruang bakar, burner, blower udara, indikator temperatur, bahan yang dibakar dan water scrubber. Selain itu, peracangan elektronika saling berhubungan sehingga insinerator dapat beroperasi dengan baik karena antarkomponen satu dengan komponen lainnya mempunyai fungsi masing-masing. Kelayakan alat peraga dari suara responden memperoleh 95%.

Abstract

This study examines a crucial problem that occurred on board the MT. Nectar, namely air contamination in the lubricating oil of the Cargo Oil Pump Turbine COPT, which is a critical system in supporting the download and unloading process of crude oil. This contamination resulted in a significant decrease in pump performance, increasing the risk of malfunction that impacts equipment safety and the operational efficiency of the ship. This problem not only has a technical impact, but also requires proper maintenance management handling. Using a qualitative approach through direct observation, interviews with crew members, and documentation studies of the maintenance and operation history of the lubrication system, this study analyzed the root cause using the SHEL (Software, Hardware, Environment, Liveware) model and Fishbone Diagram. The analysis results indicate that the main causes of contamination are leaks in the labyrinth seal, inadequate condenser vacuum, and wear on metal bearings due to suboptimal lubrication. To address this problem, the study recommends improving compliance with Plan Maintenance System PMS procedures, implementing routine and periodic inspections of the entire lubrication system, using high-quality components, and improving technical training for crew members to strengthen their understanding of the lubrication system. In addition, a digital monitoring system is needed for early detection of contaminants in the oil. These steps aim to maintain the darkness and efficiency of the COPT system to ensure optimal ship operations. This research is expected to be a useful reference for ship crews, shipping companies, and cadets at the Semarang Maritime Polytechnic PIP in understanding the importance of lubrication systems and preventing contamination in auxiliary machinery on ships.

Abstract

The Cargo oil pump is one of the auxiliary units on board a ship, used to transfer cargo from one location to another during loading and unloading operations. On the MT Pangrango vessel, an issue occurred with the cargo oil pump: its performance declined, resulting in slow suction during the unloading process. This problem hindered efficient cargo operations, as the pump was not functioning properly.This study aims to identify the contributing factors, impacts, and countermeasures for the decreased performance of the cargo oil pump. The research methodology applied in this thesis involved a descriptive approach combined with Miles and Huberman’s analytical method, with data validity tested via triangulation. Data collection techniques used to identify the problem included observation, interviews, documentation, and literature review.The results revealed that the pump’s shaft was worn due to excessive friction, and the ball bearing s exhibited wear and disintegration caused by lack of lubrication (grease). The recommended corrective actions were to add material to the shaft , perform realignment to correct any shaft misalignment, and implement routine maintenance—specifically, monthly grease lubrication. These measures, when properly applied, can significantly reduce the risk of Cargo oil pump damage.

Abstract

Abstract The FO purifier auxiliary aircraft on board is a critical auxiliary machine in the fuel system. It separates fuel oil from air, mud, and dirt. When the researcher was conducting sea practice on the MV Manalagi Tara, the FO purifier auxiliary aircraft experienced damage, resulting in the release of oil into the sludge channel of the FO purifier, which caused a decrease in FO purifier performance. Then, the FO purifier was immediately turned off by Engineer Four before more oil came out, which caused a reduction in fuel oil. Purpose - This study is to determine the factors causing the reduced performance of the bowl rotation on the FO purifier, the impact of the malfunction of the bowl rotation, and the failed performance of the bowl rotation on the FO purifier. Methodology – The research method employed in this thesis is qualitative, utilizing the fishbone analysis technique. Findings – The results from this study indicate that the factors causing the lack of bowl rotation performance on the FO purifier are dirty bowls, loose flat belts, damaged bowl shaft bearings, and worn bowl shafts. The impacts are caused by factors contributing to the lack of bowl rotation performance on the purifier. Efforts that can be made so that the rotation performance on the FO purifier can operate normally are cleaning the FO purifier bowl, adjusting the flat belt, replacing the bearing shaft, and the shaft bowl with new ones. Originality – Understanding of mechanical condition and material degradation influence purifier performance in real ship operation
