Abstract

This study investigates the optimization of Wageningen B-series marine propellers using a CFD-based approach combined with numerical solver techniques to improve hydrodynamic performance under operational constraints. Key design parameters, including blade number, diameter, pitch ratio, and expanded area ratio, were optimized while satisfying thrust, cavitation, and structural limits. Propeller performance was evaluated in terms of thrust coefficient (KT), torque coefficient (KQ), and open water efficiency (η), with and without the application of Propeller Boss Cap Fins (PBCF). The optimized configuration consists of a three-bladed propeller, achieving a maximum efficiency of 0.51347 while meeting all imposed constraints. Results show that the inclusion of PBCF reduces KT, KQ, and η at low to moderate advance coefficients, but yields efficiency improvements at higher advance coefficients, particularly at J = 0.8. The findings demonstrate that CFD-based constrained optimization provides an effective alternative to conventional chart-based propeller design methods and highlights the importance of matching propeller modifications to specific operating conditions.

Abstract

This research aims to analyze the casting process of an impeller used in a marine water jet propulsion system using the sand casting method, assisted by ProCAST simulation software. Two gating system designs were compared: one without a riser and one with a riser, along with three pouring temperature variations (630°C, 660°C, and 680°C) to identify casting defects. Simulation results show that the design with a riser produced a total shrinkage porosity of 6.67%. The solidification time for the design without a riser was recorded at 225 seconds, while the design with a riser reached 282 seconds. The Niyama criterion for the design without a riser ranged from 3.70 to 7.40 (k.sec)^0.5/cm, while the design with a riser increased to 4.96 to 9.93 (k.sec)^0.5/cm. Among the three pouring temperature variations, 660°C provided the most optimal results. The combination of riser design and 660°C pouring temperature yielded the best casting quality.

Abstract

The operational readiness of Indonesian Navy warships (KRI) depends heavily on the reliability of Very Small Aperture Terminal (VSAT) systems, which serve as the backbone of satellite communication in naval operations. This study aims to analyze the competency of Communication and Electronics Service (Diskomlek) personnel at the First Fleet Command (Koarmada I) in maintaining VSAT systems and its implications for system reliability. A qualitative approach with an intrinsic case study design was employed, involving 18 purposively selected participants. Data were collected through semi-structured in-depth interviews, participant observation, and document analysis, then analyzed using NVivo 14. The findings reveal that personnel competency encompasses three dimensions: technical knowledge, practical skills, and professional attitude. Strengths lie in theoretical knowledge and discipline in preventive maintenance, while weaknesses are found in advanced practical skills, independent troubleshooting capabilities, and proactive fault detection. Corrective maintenance faces challenges due to prolonged repair times, with modem failures reaching 24 incidents annually (mean repair time 8.5 hours) and antenna failures reaching 15 incidents annually (mean repair time 12 hours). Organizational factors, including limited spare parts availability, training systems insufficiently oriented toward practical needs, and personnel rotation policies disrupting expertise continuity, further weaken the relationship between competency and system reliability. This study concludes that capacity building through continuous education, simulation-based training, technical certification, and improved maintenance management systems is essential for ensuring communication reliability in naval operations.

Abstract

The design of Ro-Ro ferries with low payload capacities requires a more detailed analysis, as it significantly influences vessel comfort during navigation. This study presents a case study of ferries operating on the short Bengkalis – Sungai Pakning route as an alternative solution, addressing the frequent fluctuations in passenger and vehicle demand. Consequently, during peak periods, the existing Ro-Ro capacity becomes insufficient, leading to extensive queues. Conversely, during low-demand periods, the current vessels become economically inefficient, as they often delay departure until reaching full capacity to prevent operational losses. The proposed solution involves a comparative analysis of three ship models with varying load capacities to identify the optimal configuration in terms of stability and speed performance. Utilizing an analytical modeling approach, the results indicate that Model-1 exhibits superior stability performance, characterized by principal dimensions of L = 42.3 m, B = 11.8 m, H = 3.1 m, T = 2.03 m, and a payload of 78.25 tons.

Abstract

Fire extinguishers are very important to ensure the safe operation of the ship and must meet the applicable regulations, in accordance with the objectives of the Safety of Life at Sea (SOLAS), contains one of the international conventions which contains Operational Readiness and Maintenance of fire extinguishers. fire extinguishers. Fire on board a ship is a serious threat that requires quick and effective handling to prevent major losses. A dry powder type fire extinguisher (APAR) is one of the main solutions in dealing with fires in the maritime environment. However, the effectiveness of APAR depends on optimal use and maintenance. This research aims to optimize the use and maintenance of dry powder ship type APARs in preventing the above fires. The research method involves field surveys on several ships to practice the use and maintenance of APARs. In addition, statistical analysis is used to identify factors that influence APAR performance.
