Abstract

The study on the use of the Smith Bracket in towing operations highlights its critical role in securing towing connections, requiring strong structural integrity as mandated by IMO safety regulations. Using Finite Element Method (FEM) analysis, the stress distribution under various tensile loads was examined, and the simulation results indicate that the bracket design can safely withstand operational forces, making it suitable for towing applications.From the calculations: The Minimum Break Load (MBL) of the Smith Bracket is determined to be ±69 tons, Applying a Safety Factor (SF) of 4, The Safe Working Load (SWL) is calculated at 17.5 tons. These values indicate that the bracket meets safety requirements and is capable of withstanding operational loads without failure. The combination of IMO regulations, FEM simulations, and theoretical analysis ensures that the Smith Bracket is designed for safe and reliable towing operations.

Abstract

Rainfall is a vital climate component and its variability in equatorial regions such as Indonesia. Bengkulu City, with its strategic geographical position on the edge of the Indian Ocean, is influenced by global and regional climate, as well as local conditions such as topography and sea surface temperature. Air humidity is known to be significantly correlated with extreme rainfall, while wind speed plays a role in air convergence and cloud formation. Therefore, this research tends to examine the air humidity, wind speed and sea surface temperature’s influence on rainfall in Bengkulu City. The method employed in this research is quantitative technique with multiple linear regression analysis using SPSS model. The data employed are monthly data of air humidity, wind speed, sea surface temperature, and rainfall from 2003 to 2023. As model validation before regression analysis, normality and multicollinearity tests were conducted. The analysis outcomes present that air humidity has a significant and positive partial effect on rainfall, which is consistent with its role in the condensation process and cloud formation. In contrast, wind speed and sea surface temperature show no significant partial influence on rainfall. However, simultaneously, these three independent variables (air humidity, wind speed and sea surface temperature) have a significant effect on rainfall. The regression model was able to explain about 63.8% of the variation in rainfall, confirming that air humidity is the main predictor of rainfall in the Bengkulu region.

Abstract

Abstract: Accurate forecasting of container throughput is vital for enhancing strategic planning and operational efficiency in seaport management. This study compares the performance of two time series forecasting models Seasonal Autoregressive Integrated Moving Average (SARIMA) and Long Short-Term Memory (LSTM) in predicting container throughput at Tanjung Emas Port, Semarang, Indonesia. Monthly throughput data from January 2014 to April 2025 were preprocessed using stationarity transformation and normalization techniques. Model performance was evaluated using Mean Absolute Percentage Error (MAPE), Root Mean Squared Error (RMSE), and Mean Absolute Error (MAE). The SARIMA model effectively captured seasonal patterns and produced accurate short-term forecasts. Conversely, the LSTM model exhibited notable significant deviation from the actual data , indicating lower predictive performance in this context. The findings indicate that SARIMA currently provides a more reliable forecasting approach for the port. Future research should consider hybrid models (e.g., SARIMA-LSTM) and incorporate exogenous variables to improve forecasting accuracy and support data-driven decision-making in port operations.

Abstract

The handling of dangerous goods in port environments represents one of the most critical safety challenges in maritime logistics, necessitating comprehensive risk management approaches and advanced safety protocols. This systematic literature review analyzes current practices, challenges, and innovations in dangerous goods handling at ports, examining safety management systems, risk assessment methodologies, and technological solutions. Following PRISMA guidelines, 37 peer-reviewed articles published between 2014-2024 were systematically analyzed based on their relevance to dangerous goods handling, port operations, safety management, and risk assessment in maritime environments. The analysis reveals five key themes: risk assessment and safety management systems, regulatory frameworks and compliance, technological innovations and automation, human factors and training, and environmental impact and sustainability. Major findings indicate that integrated risk-based approaches, combined with advanced detection capabilities and comprehensive training programs, significantly enhance safety outcomes in dangerous goods handling. The research emphasizes the critical need for holistic safety management systems that integrate technological solutions, regulatory compliance, human factor considerations, and environmental protection measures. Current evidence suggests that ports implementing comprehensive safety management frameworks demonstrate substantial improvements in incident reduction and operational efficiency. Future research directions should prioritize the development of smart port technologies, standardized international protocols for dangerous goods management, and enhanced integration between automated systems and human decision-making processes to address emerging challenges in increasingly complex port environments.

Abstract

The shipping industry, a critical component of global logistics, faces persistent operational risks that threaten safety, environmental integrity, and economic stability. Traditional risk assessments, often reliant on descriptive statistics, fail to capture the probabilistic and multifaceted nature of maritime accidents. This study bridges this gap by developing a robust Monte Carlo simulation framework to quantify incident probabilities for a tanker fleet. Utilizing a comprehensive dataset from a shipping company, including incident reports, tanker characteristics, and root causes, the model iteratively samples operational and technical variables up to 50,000 iterations to project risk distributions and identify critical failure pathways. The results demonstrate that risk is highly contextual and not an intrinsic tanker property. The analysis reveals that mid-sized tankers (20,000–35,000 GT) are most susceptible to technical failures like propulsion and auxiliary machinery breakdowns, aligning with their high risk for asset loss and security breaches. Conversely, larger tankers (> 60,000 GT) exhibit systematically lower risk across most categories, which is attributed to advanced safety systems and stricter protocols. A notable exception is environmental risk, where smaller tankers (≤ 5000 GT) pose the lowest threat due to their limited spillage potential. The simulation achieved convergence at 10,000 iterations for personnel injury and security breach incidents, and 5000 for asset loss and environmental impacts, providing a validated threshold for reliable prediction. This study concludes that the Monte Carlo method effectively translates historical data into actionable insights, enabling proactive, precisely timed mitigations tailored to specific tanker profiles and incident types. The findings offer a paradigm shift from reactive to predictive risk management in maritime operations.

Abstract

Reclamation is a widely adopted strategy to address land scarcity by converting coastal waters into new land. This approach has been implemented in many major cities worldwide to support economic growth and infrastructure expansion, including in Surabaya. As the core of the Gerbangkertosusila National Strategic Area, Surabaya is actively pursuing coastal development, one of which is the planned integrated reclamation project, Surabaya Waterfront Land (SWL), in the Pamurbaya region. Previous studies have shown that reclamation can significantly alter hydrodynamic processes, including river discharge in estuarine channels. This study investigates changes in hydrodynamic patterns and primary channel discharges following reclamation, using numerical simulations with Delft3D. Model performance was validated with a Root Mean Square Error (RMSE) of 0.4. The results indicate that reclamation increases current velocities in the southern sector to ≥1.5 m/s, with flows between reclamation blocks ranging from 0.8–1.2 m/s. In contrast, currents in sheltered areas weaken to about 0.2 m/s. Reclamation also intensifies erosion in areas directly exposed to open flow, while promoting sediment deposition in sheltered zones. Channel discharge decreased by 20–70% after reclamation, with the greatest reductions in the Kepiting and Bokor rivers (60–70%) and the smallest in the Wonokromo River (15–20%). These findings underscore the importance of planning reclamation projects with due regard to community livelihoods and coastal ecosystem sustainability. Recommended mitigation measures include constructing connecting canals to maintain circulation, implementing staged reclamation to allow adaptive evaluation, and restoring mangrove belts along reclamation boundaries. The study highlights the value of numerical modeling as a decision-support tool for adaptive and sustainable coastal management.

Abstract

This study aims to implement the djikstra algorithm to overcome the problem of optimizing the shortest route determination in aplousing and maintenance activities of Shipping Navigation Assistance Facilities (SBNP) in the working area of the Tanjung Perak Type A Navigation District Office. The Navigation Pier has historically been a strategic facility to face the challenges of maintaining fuel efficiency, sailing times and reducing emissions in environmental pollution due to suboptimal routes. The djikstra algorithm is known to be effective in finding the shortest route on a weighted graph by representing strategic location points such as ports and marine navigation areas as nodes and the distance between nodes is calculated using the haversine formula based on geographic coordinates as weights. Before the implementation of travel route optimization, a total mileage of 1,210.30 km was obtained and after the optimization was applied using the djikstra algorithm, a total mileage of 1,110.44 km was obtained. This comparison shows a significant distance savings of 99.86 km or 8.25% travel efficiency. This optimization is able to contribute to time reduction, fuel savings and reduction of environmental pollution exhaust gas emissions so that it is able to optimize the operational effectiveness of ships as a whole. This study confirms the positive and relevant capabilities to be applied in shipping navigation route planning and support decision-making in the management of sea routes or logistics transportation in areas with a varied distribution of mileage points that require high efficiency and mobility. In the next research, it is hoped that it will be able to add external factors such as sea currents, waves, and wind according to the geographical characteristics of the territorial waters so that the results of route planning can be more accurate in the real operational area in the shipping work area.
