Abstract

Diesel engine generator merupakan permesinan yang mengubah tenaga mekanik menjadi energi listrik di atas kapal. Dalam pengoperasian generator, mesin didukung dengan sistem pendingin air tawar yang bersirkulasi agar mesin tidak menimbulkan panas yang berlebih. Pendingin air tawar ini mendinginkan komponen-komponen generator yang bergerak dan menimbulkan panas. Air tawar masuk melalui cylinder head pada seating exhaust valve untuk mendinginkan exhaust valve yang bekerja disuhu tinggi dikarenakan dari gas buang pembakaran. Kerusakan pada seating exhaust valve akan menimbulkan pengaruh besar bagi kinerja diesel engine generator. Penelitian ini membahas pengaruh kebocoran serta langkah penanganan pada seating exhaust valve generator cylinder nomor 1 di KM. Oriental Galaxy. Penelitian menggunakan metode kualitatif dengan fishbone analysis serta proses pengambilan data dilakukan dengan dokumentasi, wawancara, dan observasi. Hasil penelitian menunjukkan bahwa kebocoran sistem pendingin seating exhaust valve generator cylinder nomor 1 disebabkan oleh beberapa faktor seperti jam operasional yang melebihi dari panduan manual book dan minimnya perawatan pada mesin diesel generator. Faktor-faktor ini berdampak pada mesin yaitu penurunan suhu gas buang cylinder head nomor 1, peningkatan suhu fresh water out generator nomor 1, dan penurunan volume air pada expansion tk. Oleh karena itu, dilakukan penggantian cylinder head nomor 1 dengan sparepart yang baru agar generator dapat bekerja secara optimal dan kebutuhan listrik di kapal tetap terjaga.

Abstract

Women are human resources with potential that can be utilized in various fields. Women's MSMEs can potentially improve coastal communities' welfare, independence, and empowerment. To overcome these challenges and obstacles, women's MSME businesses on the coast of Surabaya must develop several strategies for human resources for MSME actors on the coast. The research method in this study was quantitative; questionnaires were distributed to female MSME actors on the coast of Surabaya in Tambak Wedi, Kedinding, Nambangan, Bulak, Kenjeran, and Wonorejo. Eighty-two female MSME actors have filled out the questionnaire appropriately, and the data entered is processed and analyzed using SEM PLS. This research shows that the training variable has a significant positive effect on the development of human resources for female MSMEs on the coast of Surabaya. Meanwhile, other variables, such as education, health, motivation, and involvement, do not influence the development of human resources for female MSME actors on the coast of Surabaya

Abstract

The stability of bulk carriers during high-rate cargo operations represents a critical intersection of naval architecture, mechanical engineering, and operational management. This study investigates the systemic inefficiencies in the ballast water management system of the MV Sun Winner II, a Supramax bulk carrier operating in the Indonesian archipelago, specifically analyzing the technical impediments encountered during cargo handling at Muara Berau port on February 14, 2024. Utilizing a descriptive qualitative methodology, data were acquired through direct shipboard observations, semi-structured interviews with senior deck officers, and rigorous documentation analysis over a 12-month sea service period. The research identifies a significant degradation in ballast performance attributed to sediment accumulation (sludge) exceeding 2 cm in tank bottoms, advanced corrosion of suction valves, and reduced centrifugal pump efficiency, which collectively resulted in a cargo intake shortfall of approximately 2,000 metric tons against a planned 23,000-ton capacity. The study reveals a critical dissonance between the administrative Planned Maintenance System (PMS) records and the physical reality of the vessel's ballast infrastructure, highlighting the "administrative-physical gap" as a latent risk factor. The findings suggest that on aging vessels (25+ years), standard maintenance protocols are insufficient; an enhanced regime of predictive maintenance, aggressive de-silting, and comprehensive valve overhauls is required to ensure compliance with SOLAS stability criteria and to maximize commercial voyage capability.

Abstract

This study examines practical efforts to increase Boil-Off Gas (BOG) production without relying on the Fuel Gas Pump (FGP) during ballast voyage on the M.T. Coral Energy. In this condition, the vessel carries only a small amount of heel cargo, causing limited natural evaporation and a significant drop in tank pressure, which often results in insufficient BOG supply for the main engine. These operational constraints highlight the need for an alternative strategy that is both efficient and safer for cryogenic equipment.Using a qualitative descriptive approach, the research incorporates direct observation, structured interviews with deck officers, and operational documentation from the vessel. Data were analyzed using a fishbone framework to trace the root causes of low BOG production, focusing on technical, environmental, and human-factor aspects. The findings show that applying the top spray method using the deepwell pump effectively increases tank pressure and stabilizes BOG availability during ballast voyage. This method helps maintain a consistent gas supply for propulsion without adding mechanical load or maintenance risks to the FGP. The success of this approach depends largely on accurate flow control, careful pressure monitoring, and the crew’s understanding of the operational procedure. Overall, the study concludes that top spray is a reliable and energy-efficient alternative for BOG management when FGP use is minimized. The results are expected to support LNG carrier operations, particularly in optimizing fuel systems under low-cargo condition.

Abstract

LNG cargo tanks are specifically designed to transport liquefied gas, and the coolingdown process becomes a critical stage prior to loading. This process is performed by spraying liquid gas through spray nozzles installed on the tank dome. This study employs a descriptive qualitative method, with data collected through observation, interviews, and documentation. The data were analyzed using the Miles and Huberman model, which consist of data condensation, data display, and conclusion drawing. The findings indicate that the coolingdown process on LNG/C Pan Africa generally complies with SIGTTO and IGC Code standards. However, two major issues were identified: a leakage in the cooldown valve on loading line number 2 caused by corrosion, which reduced the cooling rate from the standard 20°C/hour to approximately 10°C/hour, and a 1.5 hour delay in operating nitrogen system, which resulted in the IBS pressure not reaching the required 0.2-0.4 kPa. The study concludes that optimization of the coolingdown process can be achieved through preventive maintenance of the cooldown valve, improved coordination among officers, and enchanced accuracy in monitoring temperature and pressure. These recommendations are expected to improve the efficiency and safety pf LNG loading operations.
