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.

Abstract

The adoption of High Density Polyethylene (HDPE) as the primary material for boat structures has increased significantly in recent years. In response to contemporary challenges and to facilitate research requirements, Polytechnic of Bengkalis (POLBENG) constructed a research boat utilizing HDPE. Nevertheless, further research on the response of the HDPE structure to vibrations generated by the main propulsion engine remains insufficiently intensive. Therefore, a direct measurement of ship vibration is conducted utilizing vibration sensors, namely Witmotion WTVB02-485. Both inside and outside of the accommodation rooms, measurements were taken. By comparing the vibrational velocity's Root Mean Square (RMS) to standards established by the American Bureau of Shipping (ABS), a classification society, structural assessment was evaluated. Furthermore, resonance events were discovered by comparing the Blade Passing Frequency (BPF) with the recorded peak frequency output. The HDPE structure seems to be dependable, according to the measurement findings at both locations. The RMS of 0.020 mm/s and a peak frequency of 33.31 Hz were recorded inside the accommodation area, whereas 0.013 mm/s and 31.52 Hz were recorded outside.

Abstract

The transformation of aquaculture through digital technologies has become increasingly essential to enhance sustainability, efficiency, and competitiveness in shrimp farming. Despite its importance, the challenge of determining which regions should be prioritized for digital adoption remains unresolved, particularly in contexts with diverse production and economic conditions. This study introduces the Analytical Hierarchy Process (AHP) as a multi-criteria decision-making tool to evaluate and prioritize coastal districts in Central Java, Indonesia, for smart aquaculture development in Litopenaeus vannamei farming. AHP integrates indicators of production potential, economic feasibility, and price competitiveness into a unified ranking framework, producing clear differentiation across districts. The results highlight Cilacap, Kendal, Brebes, Purworejo, and Rembang as priority areas for early adoption of digital innovations such as IoT-based monitoring, AI-driven disease prediction, and traceability platforms. This research contributes to the operationalization of the AHP algorithm for aquaculture decision-making, contextualization of the global digital transformation framework in the Indonesian shrimp sector, and demonstrates the robustness of multi-criteria prioritization for policy planning. Although the precision of the results may be limited by the scope of the available data, the study confirms the significant role of AHP in guiding evidence-based, scalable, and adaptive strategies for advancing smart aquaculture.

Abstract

This research explores the integration of Internet of Things (IoT) technology with MEMS (Micro Electro Mechanical Systems) sensors and piezoelectric technology to enhance the efficiency and operational sustainability of devices. IoT connects physical devices to the internet to collect and exchange information and has become an integral part of Industry 4.0. The main components of IoT include physical objects, communication channels, software, operations, and data. In this study, IoT development focuses on the maritime sector with the application of MEMS sensors, piezoelectric technology, ocean current speed, and turbines. The use of piezoelectric technology allows devices to operate autonomously by harvesting energy from vibrations and pressure, further improving the efficiency of IoT devices. Experimental results show that in an open circuit, the highest average voltage at a speed of 1.1 m/s reached 0.019606 mV (capacitor) and 0.0056 mV (non-capacitor). In a closed circuit, with one non-capacitor piezoelectric, the average voltage was 14.762 mV and the average current was 0.0027 mA, producing a power output of 0.0398 mW. With four non-capacitor piezoelectrics, the average voltage reached 33.174 mV and the current was 0.0044 mA, producing a power output of 0.0146 mW. Meanwhile, with one capacitor piezoelectric, the average voltage was 4.947 mV and the current was 0.0023 mA, producing a power output of 0.01138 mW. With four capacitor piezoelectrics, the average voltage was 16.627 mV and the current was 0.0036 mA, producing a power output of 0.05986 mW. These results indicate that the piezoelectric turbine mechanism has significant potential as a reference for the development of future renewable energy technologies. The implementation of this technology allows IoT and MEMS devices to function autonomously and sustainably, supporting applications in various sectors including maritime and industry.

Abstract

Offshore platforms are large structures designed to accommodate personnel and equipment required for drilling wells in the seabed, extracting oil and/or natural gas, processing the resultant fluids, and transporting them to land by shipping or pipelines. Jacket platforms are fixed structures anchored to the seabed with piles to ensure stability against wind, wave, and current forces in the marine environment. The gradual deterioration of the fixed platform over time during operations becomes a subject of concern. The study aims to carry out a structural safety assessment (SSA) of an existing offshore platform in the Gulf of Guinea (GOG) by analyzing the reliability, risk index, safety margins, and structural integrity of the platform. A detailed investigation of design specifications, material characteristics, and environmental loads assessed the structural reliability and risk margins. A risk matrix prioritizes major structural concerns, resulting in specific recommendations for mitigation, repair, and maintenance. The platform's reserve strength ratio (RSR) was examined to build long-term structural integrity, safety, reliability, and environmental resilience strategies. The platform's safety and structural integrity were assessed using Ultimate Strength Assessment (USA) and Reliability–Risk Assessment (RRA) methods. According to the findings, corrosion, fatigue, seabed scour, subsidence, overload from environmental forces (wind, waves, currents, and earthquakes), collisions, crane accidents, explosions, falling objects, fires, leaks, accidental discharges, towing incidents, and well-related damage are the main threats to the jacket platform. The extent of corrosion and the associated probabilities of failure (POF) and reliability of the platform’s four jacket legs were calculated. The corrosion losses for Legs 1, 2, 3, and 4 were found to be 4.577%, 3.462%, 3.346%, and 4.039%, respectively. Leg 1 exhibited the highest POF (0.04577) and the lowest reliability (0.95423), whereas Leg 3 showed the lowest POF (0.03346) and the highest reliability (0.96654). The overall reliability factor of the platform was determined to be 1.0401, which, although lower than the safety load factor of 1.25, still indicates a level of structural safety. According to the risk matrix, all four jacket legs (L1–L4) fall within the “Medium” risk category for structural failure, suggesting the risk is within acceptable limits. To address corrosion-related risks specifically, cathodic protection is recommended as an effective mitigation and maintenance strategy. The Ultimate strength analysis produced an Ultimate strength of 3000 kN for a design capacity of 1250 kN, resulting in an RSR of 2.4, which is more than the minimum safety criterion of 1.50 for a manned structure, indicating that the jacket platform structure is SAFE and Fit-for-Purpose.
