Abstract

Abstract Inland container delivery constitutes a critical component of the global maritime logistics chain, acting as the final phase that connects international ports to inland destinations. Accurate prediction of inland container delivery times is crucial for enhancing operational efficiency, minimizing demurrage and detention costs, and improving customer satisfaction across global supply chains. Purpose –. This study leverages historical container movement data across key international ports to develop a robust machine learning model for predicting inland container delivery timelines. Methodology –. Using a Random Forest Regressor, the model was trained to forecast the total inland delivery time based on features such as container size, type, shipping line, dispatch weekday, and temporal patterns. Findings – The findings have practical implications for shipping lines, freight forwarders, port authorities, and inland terminal operators seeking to optimize logistics planning, reduce uncertainty, and improve supply chain. Evaluation of the model's performance yielded a Mean Absolute Error of 4.59 days, a Root Mean Squared Error of 10.55 days, and a coefficient of determination of 0.68, indicating moderate predictive accuracy. Supporting visualizations - including learning curves, gain curves, feature importance plots, residual distributions, and prediction bands - illustrate the model's strengths and areas for further refinement. Originality – The study contributes to the growing field of intelligent logistics and maritime informatics by providing a data-driven framework for improving inland delivery predictability

Abstract

Purpose - This study examines how preparation for strict Port State Control Inspections (PSCI) by the Australian Maritime Safety Authority (AMSA), influences the welfare, living and working conditions of seafarers on board PSC vessels in New South Wales. It examines how the onus of ensuring regulatory compliance for ships – particularly in terms of safety, the environment, and labor – impacts the physical, mental, and emotional well-being of seafarers. Some elements of seafarers’ welfare were examined, revealing that compliance with work/rest hours, food quality, accommodation, leadership practices, and the length of the voyage are determining factors. Methodology – A quantitative, cross-sectional research design was employed to gather information from 300 seafarers across various ranks and vessel classes. Data revealed strong demand for improvements in leadership, standardization of living conditions, management of fatigue, and regard for seafarers’ physical well-being. Findings – The findings show extensive differences in welfare between ranks, with senior (management and operational) staff reporting higher levels of fatigue, stress and dissatisfaction than support personnel. A last-minute rush of too little food, improper accommodation and disrupted work/rest hours in expectation of an imminent inspection heightened stress and fatigue. Originality –.These findings suggest that allowing sufficient time to carry out inspections and attending to the welfare of seafarers can significantly reduce stress levels, which, in turn, improves the morale of the entire crew, leading to safer.

Abstract

Abstract The FO purifier auxiliary aircraft on board is a critical auxiliary machine in the fuel system. It separates fuel oil from air, mud, and dirt. When the researcher was conducting sea practice on the MV Manalagi Tara, the FO purifier auxiliary aircraft experienced damage, resulting in the release of oil into the sludge channel of the FO purifier, which caused a decrease in FO purifier performance. Then, the FO purifier was immediately turned off by Engineer Four before more oil came out, which caused a reduction in fuel oil. Purpose - This study is to determine the factors causing the reduced performance of the bowl rotation on the FO purifier, the impact of the malfunction of the bowl rotation, and the failed performance of the bowl rotation on the FO purifier. Methodology – The research method employed in this thesis is qualitative, utilizing the fishbone analysis technique. Findings – The results from this study indicate that the factors causing the lack of bowl rotation performance on the FO purifier are dirty bowls, loose flat belts, damaged bowl shaft bearings, and worn bowl shafts. The impacts are caused by factors contributing to the lack of bowl rotation performance on the purifier. Efforts that can be made so that the rotation performance on the FO purifier can operate normally are cleaning the FO purifier bowl, adjusting the flat belt, replacing the bearing shaft, and the shaft bowl with new ones. Originality – Understanding of mechanical condition and material degradation influence purifier performance in real ship operation

Abstract

Efficient gate operations at marine container terminals (MCTs) are critical for reducing truck waiting times, minimizing congestion, and improving port economic performance. Purpose – This study develops a stochastic queuing-based optimization framework using M/Eₖ/S multi-server models to represent truck arrivals and gate service processes. Statistical goodness-of-fit tests confirmed that truck inter-arrival times follow an exponential distribution, while service times align with an Erlang distribution. Methodology – The methodology adopts a queueing–optimization framework to evaluate and improve marine container terminal (MCT) gate operations by minimizing the combined costs incurred by terminal operators and trucking companies. The gate system is characterized by two principal cost components: gate operating costs borne by the service provider and truck waiting costs incurred by users. Findings – Optimization results indicate that implementing the model reduced average truck waiting times from 9.8 minutes to 6.3 minutes and decreased total daily gate costs by approximately 23% across operating hours. The optimal number of gate lanes varied with traffic density, demonstrating the importance of adaptive lane allocation. Originality – Policy implications highlight investment in predictive analytics, dynamic scheduling, and resource allocation to enhance port efficiency, throughput, and economic competitiveness

Abstract

The modern transportation sector must consider its environmental impact particularly air pollution in addition to improving efficiency and speed. One of the main factors contributing to air pollution and global warming is the exhaust emissions produced by fossil fuel-based modes of transportation. Wing in Ground (WIG) craft are vehicles that use ground effect to fly low over water or land with lower energy consumption than conventional aircraft. This is one alternative mode of transportation that is beginning to attract attention. The literature explicitly addressing the relationship between WIG Craft design and air pollution impacts remains relatively limited; therefore, studies need to be developed that explore preventive measures to minimize air and noise pollution from this technology. Research focusing on the potential pollution and environmental impacts generated by WIG Craft is still very limited; this is because WIG Craft is a technology not yet produced for public transportation, and another factor is that research focus remains on design, stability, and control. Given these conditions, this study is important for identifying and formulating preventive strategies to reduce air and noise pollution from the use of WIG Craft. Purpose – This systematic literature review aims to comprehensively synthesize the current evidence on pollution prevention strategies in WIG craft design. Methodology – The initial phase of the study involved a systematic literature review. This Systematic Literature Review investigation was guided by the PRISMA analysis. Because of its substantial data collecting and comparatively strict and precise process. Findings – The potential emissions from WIG craft can be reduced through the design of green propulsion systems using electric power and low-carbon fuels. To mitigate the environmental footprint of Wing-in-Ground craft, researchers have proposed a combination of advanced aerodynamic design, noise suppression technologies, and optimized operational strategies.

Abstract

Marunda Port, Tanjung Priok, has a high intensity of dry bulk cargo handling, particularly coal and sand, which may increase the risk of air pollution through dust and particulate emissions. Purpose – This study aims to evaluate the governance of dry and dirty bulk cargo handling, assess air pollution conditions, and identify mitigation measures implemented at Marunda Port. Methodology – A qualitative descriptive-analytical approach was applied through field observation, semi-structured interviews, documentation, and review of official institutional reports. Qualitative data were analyzed using the Miles and Huberman interactive model, while supporting quantitative data were examined descriptively by comparing cargo handling intensity, ISPU distribution, Ambient Air Quality Status Index (ISM), and pollutant indicators including PM10, PM2.5, SO₂, CO, O₃, NO₂, dust particulate, and Pb with applicable standards. Findings – The results show that cargo handling governance has been implemented through administrative verification, equipment inspection, SOP enforcement, water spraying, dust-control nets, and routine air quality monitoring. In 2024, Marunda Port handled an average of 129 loading/unloading activities and 773,147 MT of cargo per month. North Jakarta air quality was dominated by the “moderate” ISPU category, while ISM improved from 0.59 in 2023 to 0.51 in 2024. However, PM2.5 at the KBN gate exceeded the standard. Therefore, stricter supervision, improved dust-control facilities, and integrated stakeholder coordination are required
