Isu maritim menjadi fokus utama dunia, hal ini tidak lepas dari bumi kita yang memiliki sekitar 70 persen luas lautan. Jadi penelitian tentang kemaritiman merupakan investasi jangka panjang karena memakan biaya yang banyak dan waktu yang lama, barulah dapat terlihat manfaatnya. Untuk itu, penelitian kemaritiman yang akan berdampak besar harus mendapat perhatian dan dukungan dana yang besar. Investasi untuk penelitian kelautan dapat berupa peningkatan kapasitas sumber daya manusia penelitian, pemutakhiran infrastruktur penelitian dan pembiayaan kegiatan penelitian. Oleh karena itu, diperlukan inovasi dan sinergi untuk menghasilkan penelitian teknologi maritim oleh perguruan tinggi, lembaga penelitian, dan industri yang dapat berkontribusi pada masalah ini. Selain itu, Jurnal Taman Maritim bertujuan untuk menjawab apakah penelitian tentang teknologi maritim oleh universitas, lembaga penelitian, dan industri dapat berkontribusi pada masalah Maritim Dunia. Kontribusi tersebut diharapkan dapat bertukar informasi, pengalaman, pemikiran dan juga untuk memperkuat jaringan kerjasama antar institusi, institusi, dan industri dalam skala nasional/internasional. Sehingga terjadi komunikasi ilmiah antara peneliti, industri, dan pendidikan. Fokus dan Ruang Lingkup Taman Maritim adalah teknologi dan kehidupan masyarakat yaitu Desain Bangunan Kelautan dan Perikanan. Manajemen Transportasi dan Aplikasi Teknologi Pelayaran, Energi Laut Terbarukan, Material Laut Canggih, Manajemen Pelabuhan, Pengembangan SDM Pesisir, Bencana Lingkungan Maritim, Teknik Oseanografi, serta Sistem dan Kontrol Laut.

Abstract

Tugboats play an essential role in port activities, but their cooling systems are vulnerable to failures that can potentially trigger serious accidents. This study aims to analyze the risks of tugboat cooling systems through a Formal Safety Assessment (FSA) using the Failure Mode and Effects Analysis (FMEA) method based on field surveys and accident data. Data collection was conducted via questionnaires to 12 engine room crew (including the Chief Engine Room Officer, Engineer, and Technician) and the accident investigation report of TB. Kawan Kita XI (2025), which was used as external validation by cross-refencing the documented failure causes with the high-priority FMEA result. This study identified 14 failure modes in 9 key components of the cooling system, assessed based on severity (Severity), frequency (Occurrence), and detection (Detection) on a scale of 1–10. The average value of the 12 respondents was used to calculate the Risk Priority Number (RPN) and Pareto analysis. Key findings revealed six priority risks: mechanical seal leakage (RPN=405), cylinder head cooling jacket cracking (RPN=300), freshwater pump bearing failure (RPN=243), sea chest strainer corrosion (RPN=216), temperature control valve sticking (RPN=216), and internal cooler leakage (RPN=168). These six modes accounted for 82.6% of the total risk, consistent with the Pareto principle. The uniqueness of this study lies in the integration of multi-vessel survey data, a more accurate 1–10 rating scale, and validation from actual accidents. Recommendations include preventive seal replacement, installation of leak sensors, regular valve maintenance, and anti-corrosion protection. This study contributes to strengthening the operational safety of tugboats in Indonesia.

Abstract

Accelerated wear of ladder suction pipes on the Anugerah Production Suction Vessels (KIP, Kapal Isap Produksi) poses a critical operational and safety risk in offshore tin mining activities in Bangka Belitung, Indonesia. This study presents a HAZOP-informed risk assessment covering five system nodes of the Anugerah KIP suction pipe: the inlet (Node 1), main suction pipe (Node 2), joint (Node 3), suction pump (Node 4), and spiral pipe (Node 5). Risk scores were obtained by multiplying median likelihood and consequence ratings from structured expert questionnaires completed by fifteen respondents with direct field and technical experience. Node 2 received the highest risk score of 25, placing it in the Extreme category. Node 1, 4 and 5 each scored 12 (High), while Node 3 scored 9 (Moderate). The dominant degradation mechanisms are particle erosion from abrasive slurry and electrochemical corrosion driven by the tropical marine environment. Among the priority mitigation measures identified are material substitution with wear-resistant alloys, installation of a pressure relief valve, periodic ultrasonic thickness monitoring, and replacement of the pump impeller with Ni-hard material. Wear rates drawn from the literature on comparable slurry conditions are used as order-of-magnitude benchmarks only. Post-mitigation residual risk at Node 2 is estimated to fall from Extreme to Moderate when engineering controls are applied in combination. A full life-cycle cost analysis is proposed as a next step for future work.

Abstract

Given that IMO data shows that approximately 80% of ship accidents are caused by human error, maritime safety is of paramount importance to the maritime industry. The objective of this study is to analyze the implementation of Life Saving Appliances (LSA) on the KM. Armada Segara, identify the challenges encountered, and evaluate their effectiveness in ensuring the safety of life in accordance with Chapter III of the SOLAS Convention. This study employed a descriptive qualitative method. Data were collected through document analysis, observation, and in depth interviews with four informants (Second Officer, Third Officer, Boatswain, and Able Bodied Seaman). The Miles and Huberman model was used to analyze the data. The study found that the Life Saving Appliances (LSA) available on the KM. Armada Segara meet SOLAS requirements, including life jackets, lifeboats, liferafts, and lifebuoys, as well as certification documentation and a well-maintained Planned Maintenance System (PMS). However, technical issues included problems with the lighting systems on four life jacket units, a failure in the lifeboat davit retrieval system, and human factors such as crew hesitation during the engine room fire incident. The study found that although the implementation of Life Saving Appliances (LSA) is technically and administratively sound, their effectiveness in emergency situations depends heavily on the crew’s skills and preparedness, making it necessary to provide better training and consistently improve the safety culture.

Abstract

Freshwater availability is a critical operational requirement for liveaboard phinisi vessels, particularly on routes where shore-based supply is limited or costly. This study evaluates the technical feasibility, financial viability, and business-model implications of installing a 15 m³/day marine seawater reverse osmosis (SWRO) system on the tourism phinisi vessel KLM GT 255. The assessment integrates seven-day freshwater balance analysis, engine-room integration and risk assessment using a 5 × 5 risk matrix and Bow-Tie method, financial evaluation using NPV, IRR, BCR, and Payback Period, and strategic analysis using the Business Model Canvas. The results show that the SWRO system can meet the vessel’s estimated freshwater demand of 4.7 m³/day and eliminate deficits during seven-day trips under controlled operation. Product-water TDS was measured at 450 mg/L, while identified integration risks can be reduced to acceptable levels through appropriate operational controls. With a CAPEX of Rp214 million, the Sorong-plus-delivery scenario produced an NPV of Rp344.49 million, an IRR of 41.1%, a BCR of 2.61, and a payback period of 2.35 years. However, financial performance is strongly route dependent and becomes less attractive where low-cost port freshwater is readily available. The BMC analysis indicates that SWRO primarily strengthens operational self-sufficiency, freshwater security, and service continuity rather than creating a new revenue stream. Overall, onboard SWRO is technically feasible and economically attractive for liveaboard operations exposed to high freshwater logistics costs.
