Abstract

The structural response analysis of an aluminum speedboat during slam-ming due to regular waves was conducted using the one-way fluid-structure interaction method. This method involves generating waves through hydrody-namic diffraction to obtain loads, which are then applied to the ship's struc-ture and analyzed using finite element analysis. It is known that the greater the force generated from slamming , the stress and deformation at the critical load point will increase. In addition to being influenced by the critical point, the maximum stress is also influenced by the ship's construction design. It has been found that the highest stress and deformation occur on the surface of the plate that is not supported by the transverse construction. Therefore, it can be concluded that the construction design can influence the magnitude of the structural response to the slamming event . Efforts that can be made by ship designers and manufacturers are to convert ships by using materials that are better at absorbing loads, such as the use of sandwich materials

Abstract

The Automatic Identification System (AIS) is central to vessel monitoring, traffic management, and maritime safety, yet concerns remain regarding its reliability due to incomplete, inaccurate, or delayed reporting. This study assesses AIS data from the Indonesian maritime domain, focusing on four parameters: completeness, accuracy, consistency, and timeliness. AIS records data were preprocessed through data cleaning, filtering, and detection of missing values in static fields such as draught, beam, LOA, deadweight, and gross tonnage (GT). Statistical and spatial-temporal analyses using Python were applied to quantify missing data, identify anomalies, and evaluate reporting intervals. Results show high completeness (97.5%), although missing draught data (6.77%) limited under-keel clearance assessments, while small gaps in beam and LOA affected collision risk modeling and berth allocation. Accuracy was moderate, with invalid speed and course records observed, whereas consistency was excellent, with MMSI and ship names fully aligned. Timeliness proved weakest, with median reporting intervals (8,380 seconds) exceeding IMO standards, restricting real-time navigational use but remaining suitable for long-term monitoring. Overall, AIS in Indonesia is reliable for strategic traffic analysis but insufficient for operational safety management. Strengthening reporting compliance, integrating port and registry databases, and applying anomaly detection and satellite AIS are recommended to enhance maritime safety.

Abstract

Ergonomics in the workplace plays a vital role in reducing the risk of musculoskeletal disorders, preventing accidents, and improving both work efficiency and productivity. In shipbuilding welding activities, workers are frequently exposed to awkward and static postures that lead to fatigue, stress, and long-term injuries, which may compromise weld quality and project performance. This study aims to analyze ergonomic risks across four welding postures i.e., downhand, vertical, horizontal, and overhead, using the Rapid Entire Body Assessment (REBA) and Nordic Body Map (NBM) methods. The REBA assessment indicated that downhand welding scored 10 (high risk), vertical welding 11 (very high risk), horizontal welding 8 (high risk), and overhead welding 9 (high risk). NBM results revealed that 77.5% of welders in vertical welding reported waist pain, 72.5% calf pain, and 70% back pain; horizontal welding showed 67.5% right-hand pain and 65% right-wrist pain; overhead welding resulted in 57.5% neck and waist pain; while downhand welding still caused 70% complaints in the back and calves. These findings confirm that welding ergonomics directly affect worker health, weld quality, and productivity. The study recommends ergonomic interventions such as scaffolding, adjustable supports, arm rests, and proper work rotation to minimize strain, enhance safety, and ensure efficiency in shipyard operations.

Abstract

As one of the largest archipelagic countries with a port system that supports more than 90% of its trade volume, Indonesia faces an urgent need to implement the green port concept to minimize environmental impacts, improve energy efficiency, and support national decarbonization commitments. One example is the Tanjung Perak Port, specifically the Jamrud Terminal in Surabaya. This study takes Jamrud Terminal—which provides loading and unloading services for general cargo, passengers, and dry bulk—as a case study. The terminal operates 24 hours a day and thus undoubtedly contributes to pollution, including air pollution from exhaust gas emissions, which are increasing due to a 23.06% growth in vehicle handling activities throughout 2024. Quantifying greenhouse gas (GHG) emissions from the main quay equipment and supporting equipment at Jamrud Terminal is crucial to assess current fossil fuel energy consumption and propose technological interventions to enhance energy efficiency and reduce GHG intensity from fuel usage.This paper aims to identify and calculate the existing direct emissions, analyze the trend of GHG emissions from port equipment, and develop a projection model of GHG emissions from equipment at Jamrud Terminal. The equipment includes Harbour Mobile Cranes, Harbour Portal Cranes, Excavators, Forklifts, Mobile Sweepers, Wheel Loaders, and Generators, with data sourced from primary records of fuel consumption supplied during the 2022 to 2024 period. GHG emissions projection is modeled using the Default Emission Factors method and the Direct Monitoring of Greenhouse Gas Emissions (DMGGE) approach. The results show that from 2022 to 2024, Jamrud Terminal emitted approximately 7.1 tons of CO2eq from stationary combustion and 5,378.88 tons of CO2eq from mobile combustion.A future decarbonization scenario developed in this study indicates that if the terminal transitions to electrification and the use of alternative energy fuels such as LPG or CNG, CO2 emissions could be reduced by as much as 98.6%. The results of this paper will be valuable in formulating effective planning, policies, and strategies to reduce GHG emissions from direct sources related to both main and supporting equipment at Jamrud Terminal.

Abstract

Lubrication oil purifiers are essential for the optimal performance and longevity of marine engines. On board the MV. SEAPEAK GLASGOW, we encountered an issue with the Alfa Laval purifier, where alarm A57 indicated an oil leak from the bowl, accompanied by a drop in PT4 pressure and reduced bowl speed. This investigation aimed to identify the root causes of the leakage and recommend maintenance strategies to prevent future occurences. Using a qualitative approach, we conducted onboard observations, interviews with the third engineer, and a review of maintenance records. A fishbone diagram analysis revealed several contributing factors, including wear on the water block filter, scale buildup on internal components, and a lack of understanding of maintenance procedures among the engineering staff. The findings underscored that neglecting structured maintenance schedules and inadequate routine monitoring resulted in system inefficiency. As a corrective measure, an auxiliary filtration system was installed to protect and reduce scale accumulation. To further mitigate these issues, we recommend aligning maintenance activities with the purifier’s running hours and increasing the frequency of pressure checks. These actions will help minimise the risk of oil leaks and ensure consistent performance.

Abstract

Optimizing logistics costs and service capacity is a critical focus in modern supply chain management, particularly for connecting ports to inland "hinterland" areas. This paper investigates how inter-port cooperation, strategic service bundling, and enhanced connectivity can improve logistics cost efficiency in these regions. The methodology combines an in-depth literature review with a bibliometric analysis using VOSviewer and Publish or Perish software. The literature review focuses on five key dimensions: hinterland connectivity, inter-port cooperation, cost efficiency, bundling strategies, and service improvement. The findings indicate that a strategic combination of inter-port collaboration and logistics service bundling significantly enhances logistics cost efficiency in the hinterland region. The bibliometric analysis also identifies key research clusters and highlights opportunities for future studies, particularly in under-researched regions like Indonesia, where green port implementation is underway. These findings have important implications for managers and policymakers in developing collaborative strategies to improve supply chain performance. The study concludes by proposing several hypotheses for future research concerning transportation costs, user priorities, and the performance of collaboration models.

Abstract

The design of the Temperature and Fire Monitoring Interface using Visual Basic Programming aims to detect fires at any time on the ship, especially in the main engine and diesel generator rooms. If the ship's initial conditions in the Main Engine room and diesel generator room are created to cause a fire, the tool will send a fire hazard signal which can be directly monitored by the ship's crew so that prevention can be carried out as early as possible. This design uses two smoke sensors and temperature sensors as inputs, one Arduino Uno microcontroller as a controller, one PC / Laptop as an interface for monitoring temperature and smoke conditions. The result of this system is that if the input temperature sensor and smoke sensor do not detect a fire hazard, the interface output displays a green color. If the temperature and smoke sensor input detects a fire hazard, the interface output will print red, and the buzzer output will light up as set by a visual basic program.

Abstract

The warehouses on land are rooms that are prone to fire hazards. The Spare Parts warehouse contains engine spare parts, rubber lifeboats, ship paint, thinner, maritime equipment, lubricating oil, dry food, and other logistics support. These materials have a high level of vulnerability to fire hazards. Thus, the danger of fire is one of the potential threats that can occur in Dismatbek. A fire protection system is needed that can minimize losses due to fire. This research is intended to develop a design for a fire extinguisher nozzle drive mechanism with Android monitoring and control. By building a mechanical movement mechanism for the nozzle in the vertical and horizontal directions so that the focus can be directed to the fire source with the Esp 32 Microcontroller. There is a monitoring and control unit via an Android smartphone which is equipped with three sensors, namely fire, temperature, and smoke sensors which are connected to an Arduino microcontroller to identify fire hazards. From the overall test results, it was found that the nozzle was successful in moving vertically and horizontally with a good mechanism for driving the fire nozzle arm in transmitting the power distributed to the nozzle arm resulting in a gear ratio of 2.06: 1 with a final rotational speed of 3.8 rpm at In the elevation direction, the torque is 1,606 Nm and in the azimuth direction, the speed is 7.28 rpm, the final torque is 3,028 Nm. The fire nozzle monitoring and control unit is capable of detecting potential fire hazards and the nozzle can be controlled with an Android smartphone and can extinguish fires by spraying water at the source of the fire well.

Abstract

One of the most popular sports events in Indonesia is football. In running high-tension football matches, safety and security factors are of utmost importance. There are many potential risks in a football match that could endanger the safety of spectators, players, officials, and event organizers, such as the risk of riots. This study aims to analyze the inherent risks affecting the pre-event stage of a football match at the Gelora Bung Tomo Stadium, Surabaya. Additionally, this research analyzes and determines the risk assessment at the pre-event stage in terms of human, environmental, operational, and financial aspects using Likelihood and Severity analysis. The outcome of this research is the development of a risk assessment information system by implementing Crowd Risk Mitigation Technologies (CRMT) to support more effective and predictive risk management. The data and information processing is based on variables and indicators that affect the potential occurrence of an event (likelihood) and the adverse impact if the event occurs (severity). Indicators are assigned weighted values according to the event scale, such as low, medium, and high risks, resulting in a Risk Matrix. The risk value results will be implemented in the Crowd Risk Mitigation Technologies (CRMT) application program, which serves as a tool to facilitate the initial mapping of the pre-event conditions for a football match. This study aims to analyze Inherent Risk at the pre-event stage of a football match at Gelora Bung Tomo Stadium. The analysis process uses likelihood and severity approaches to assess the probability and impact, resulting in a Risk Matrix. The findings show that human risk has the highest relative risk index (77.5%), related to potential conflicts and violations, environmental risks have a relative risk index of 16.3%, indicating risks of facility damage, and operational risks have a relative risk index of 6.4%, indicating dominant risks related to system failures and coordination issues. The potential financial loss reaches 1.53 billion Rupiah (very high level), with the largest contribution from human risks (888 million Rupiah), followed by operational (375 million Rupiah) and environmental risks (250 million Rupiah). With a structured and cross-data approach, the Crowd Risk Mitigation Technologies (CRMT) application is implemented as a tool for assessing pre-event football risks.
