The reliability of boiler performance is highly dependent on the combustion system, particularly the pilot burner and main burner. Inadequate maintenance of these components may lead to combustion failure, delayed boiler start-up, increased fuel consumption, and potential safety hazards. This study aims to analyze the actual condition of the pilot burner and main burner and to evaluate maintenance optimization efforts on the boiler of MV Habco Ankaa. The research employs a qualitative descriptive method with a case study approach. Data were collected through direct observation in the engine room, interviews with engine crew members, and documentation review including engine log books, maintenance records, and manufacturer manuals. The results indicate that the main causes of boiler combustion problems are clogged burner nozzles, improper pilot burner electrode spacing, and the lack of effective preventive maintenance implementation. Maintenance optimization through routine cleaning, electrode adjustment according to standards, and the application of a Planned Maintenance System (PMS) has proven effective in in improving flame stability, facilitating smoother boiler start-up, and enhancing combustion efficiency. In conclusion, systematic and continuous maintenance of the pilot burner and main burner plays a crucial role in maintaining boiler reliability, improving ship operational efficiency, and ensuring engine room safety.

GRIYA AMBON TERHADAP LINGKUNGAN LAUT PRATAMA, ANGGA The increasing intensity of international shipping activities has made the use of ballast water an essential part of ship operations. Ballast water functions to maintain ship stability, trim, and safety; however, it also poses a risk of transporting non-indigenous species, pathogenic microorganisms, and pollutants that can disrupt marine ecosystems. The discharge of untreated ballast water may lead to marine environmental pollution and the spread of invasive species. In response to this issue, the International Maritime Organization (IMO) established the Ballast Water Management Convention (BWMC), which requires ships to manage ballast water in accordance with prescribed standards, particularly through the implementation of Ballast Water Treatment Systems (BWTS) in compliance with the D-2 standard. This study aims to analyse the impact of the implementation of Ballast Water Treatment System (BWTS) on board MT. Griya Ambon in preventing marine environmental pollution, as well as to compare the effectiveness of ballast water exchange methods with the use of BWTS. The research employs a qualitative method with a case study approach. Data were collected through direct observation during sea practice on board MT. Griya Ambon, interviews with ship officers, and documentation studies of ballast water management procedures and operational records. The results of the study indicate that ship ballast water has significant potential to pollute the marine environment if it is not properly managed. The ballast water exchange method is considered less effective because it only relies on dilution, is highly dependent on weather and ship safety conditions, and is unable to eliminate microorganisms completely. In contrast, the application of Ballast Water Treatment System (BWTS) is proven to be more effective in inactivating living organisms through filtration and treatment processes, thereby meeting the IMO D-2 standard and reducing the risk of marine pollution. Therefore, the implementation of BWTS represents a safer, more effective, and sustainable solution for ballast water management, particularly on-board MT. Griya Ambon.

MERATUS LEMBAR NUR MUBIN, MUHAMMAD The Fuel Oil Purifier (F.O Purifier) is an auxiliary machinery on board a ship that functions to separate fuel oil from water and impurities before it is supplied to the main engine. An unoptimized performance of the F.O Purifier can reduce fuel quality and directly affect the combustion process and the performance of the main engine. This research aims to analyze the causes of incomplete fuel oil purification and the factors contributing to the ineffective implementation of the Planned Maintenance System (PMS) on the F.O Purifier onboard MV. Meratus Lembar. This study employed a descriptive qualitative research method. Data were collected through direct observation during sea practice, interviews with engine officers, documentation, and literature study. The collected data were analyzed by comparing actual operational conditions with the procedures stated in the Instruction Manual Book. The results indicate that the incomplete fuel oil purification was mainly caused by improper selection of gravity disc size, fuel oil heating temperature that did not reach the optimal range of 95°C–98°C, and dirty bowl discs due to excessive sludge accumulation. In addition, the Planned Maintenance System was not implemented optimally due to tight sailing schedules, limited spare parts availability, and insufficient maintenance supervision. These conditions resulted in frequent clogging of filters and main engine injectors, increased exhaust gas temperature, and unstable engine performance. Corrective actions were carried out by selecting the appropriate gravity disc according to the fuel oil specific gravity, maintaining optimal fuel oil temperature, performing regular bowl disc cleaning, and implementing the Planned Maintenance System in a disciplined and scheduled manner. Through these measures, the performance of the F.O Purifier can be optimized, leading to improved fuel quality and more efficient and reliable main engine operation.

Untuk mengatasi permasalahan tersebut, Korea Selatan memberlakukan Emission Control Area (ECA) guna membatasi kadar sulfur bahan bakar kapal hingga maksimum 0,1% m/m. Penelitian ini bertujuan untuk menganalisis efektivitas penerapan ECA dalam mengurangi emisi sulfur di wilayah perairan Korea Selatan, serta meninjau faktor-faktor yang memengaruhi keberhasilannya. Metode penelitian yang digunakan adalah kualitatif deskriptif melalui studi literatur dan analisis dokumen, serta didukung observasi langsung selama praktik laut (PRALA) di kapal MV Boyang Alaska pada periode Januari 2024–Januari 2025. Data diperoleh dari dokumen International Maritime Organization (IMO), Ministry of Oceans and Fisheries (MOF), Korea Maritime Institute (KMI), serta laporan kualitas udara Korea Environment Corporation (KECO). Hasil penelitian menunjukkan bahwa penerapan ECA di Korea Selatan efektif menurunkan konsentrasi SO₂ di pelabuhan utama seperti Busan, Incheon, dan Ulsan dengan penurunan mencapai 48–64% sejak regulasi diberlakukan pada tahun 2020. Tingkat kepatuhan kapal terhadap penggunaan Low Sulfur Fuel Oil (LSFO) berada pada angka 98,2%, didukung oleh pengawasan Port State Control, ketersediaan infrastruktur bunkering LSFO, dan penegakan regulasi yang tegas. Namun demikian, tantangan masih ditemukan seperti perbedaan pemahaman teknis awak kapal, tingginya biaya LSFO, serta ketidakmerataan distribusi bahan bakar sulfur rendah di beberapa pelabuhan. Kesimpulan penelitian menunjukkan bahwa kebijakan ECA di Korea Selatan berhasil mengurangi emisi sulfur secara signifikan dan meningkatkan kualitas udara di wilayah pelabuhan. Peningkatan efektivitas kebijakan dapat dicapai melalui penguatan infrastruktur LSFO, pelatihan awak kapal, serta pemantauan emisi berbasis digital. 2026-04-20T00:00:00Z
