Abstract

Awareness of sailing safety ls vital and must be prioritized. Various incidents of ship accidents, starting from burning ships and sinking became a separate evaluation material for Indonesia which declared it to be the world's maritime axis. The problem of the lack of safety equipment available on ships are found in cases of passenger ship accidents in Indonesia. This is also found in fishing vessels belonging to groups and individuals. The main reason stated by the ship owner is that the procurement of safety equipments requires no small amount of funds, and priority needs of each of the different safety equipments so that not all equipment need to be fulfilled, In addition, the low level of education and skills also affects safety awareness. The type of research used is Explanatory Research which aims to analyze whether or not the influence of the amount of fishermen's income on sailing safety awareness is mediated by education level. The number of research samples is 59 respondents who are fishermen on the North Coast of Java (Semarang, Demak, and Kendal). The research data was obtained through filling out questionnaires using a Likert scale with a range of 5. In addition, it was also strengthened by follow-up interviews to support the results of research data processing. From the results of the research data obtained results: (1) the amount of income did not affect the level of education, (2) the amount of income did not affect sailing safety awareness. (3) the level of education had a positive effect on sailing safety awareness and (4) the level of education was not mediates the effect of the amount of income on sailing safety awareness.

Abstract

Ironwood (eusideroxylon zwageri) is a type of wood that has great potential for industrial development. Currently, forest exploitation activities and the wood industry produce 30%-60% solid wood waste and have not been utilized optimally. One way to use it is to make composite materials. The purpose of this study was to determine the most optimal drying technique of ironwood powder, to provide information on the morphology, content and functional groups as well as the mechanical strength of the biocomposite with a volume fraction ratio. The ironwood powder samples in this study were characterized using the SEM-EDX, FTIR, and Vickers hardness tests. The results of the SEM test obtained information that the morphology of all samples had similarities, namely the surface was rough and the measured diameter of the sample ranged from 50-100 µm. While the EDX test obtained information that all samples had high carbon and oxygen content. The FTIR test results showed that ironwood powder had a cellulose content as evidenced by the absorption peaks and chemical bonds that were the same as pure cellulose. The results of the mechanical test on the biocomposite showed that sample C had the highest average HV value of 13.3 N/m2, while sample E had an average HV value of 12.26 N/m2 below the HV value of sample E. Meanwhile, sample A obtained the lowest hardness value with an average HV 5.93 N/m2.

Abstract

The optimization of cargo loading processes plays a crucial role in maritime logistics operations. This study is focused on examining jumbo bag loading procedures aboard MV Royal Glory, identifying various influencing factors, and establishing management methods for damaged jumbo bags. Using a qualitative-descriptive approach, data was collected through field observations, in-depth interviews, and documentation during sea practice. Research findings show that while loading procedures are systematically structured, their effectiveness remains limited as they rely on manual calculations and crew expertise without technological support. Three primary constraints identified include human resources, equipment and facilities, and cargo materials. Although measures for handling damaged jumbo bags have been implemented, preventive actions have not yet been adopted. This situation leads to reduced operational time efficiency and heightened occupational safety risks.

Abstract

The hatch cover is an important component on bulk carrier vessels that supports cargo protection and loading-unloading operations. Damage to the hatch cover may disrupt operational activities, increase accident risks, and cause delays in coal distribution. This study aims to analyze hatch cover maintenance and identify critical components with the potential for failure. The research used a mixed-method approach through Reliability Centered Maintenance (RCM). Data were collected through observations, documentation, and questionnaires distributed to ship crews. The analysis methods included Functional Block Diagram (FBD), Failure Mode and Effects Analysis (FMEA), Logic Tree Analysis (LTA), and task selection. The results showed that the hydraulic pipe was the most critical component, with the highest Risk Priority Number (RPN) value of 576 due to leakage causing unstable hydraulic pressure. Other components, such as the hydraulic jack, hatch cover wheels, and chain, also showed significant failure risks affecting hatch cover performance. The recommended maintenance actions include periodic inspections, routine maintenance, and replacement of damaged components. Proper implementation of maintenance is expected to improve hatch cover reliability, operational safety, and the efficiency of bulk carrier operations.

Abstract

The Bulk Transfer System on Supply Vessels plays a crucial role in supporting offshore logistics, particularly in transferring bulk cement to drilling facilities. The system operates on pneumatic principles and is influenced by compressors, piping networks, mechanical components, and control devices. However, the current maintenance approach remains reactive, increasing the risk of recurring operational failures. This study aims to evaluate system reliability and determine an optimal risk-based maintenance strategy using Reliability Centered Maintenance (RCM). The analysis includes system function identification, Failure Mode and Effect Analysis (FMEA), and Logic Tree Analysis (LTA). The results show that the transfer pipeline has the highest risk (RPN 48), followed by the air compressor unit, air receiver tank, and safety system (RPN 36). LTA indicates that most failures are evident with Operational Consequences, while safety system failures are categorized as Safety Consequences. The application of RCM effectively improves overall system reliability.
