Abstract

Compression ignition engines play a critical role in various industrial and transportation applications; however, their environmental impact remains a major concern. Continuous research efforts have been directed toward optimizing engine performance to enhance efficiency and reduce emissions. This paper reviews key strategies that have been investigated for performance optimization, primarily focusing on combustion chamber geometry, fuel properties, and advanced combustion modes. Each of these factors significantly influences the combustion process, thereby affecting engine performance and emission characteristics. While no single method has proven sufficient to fully resolve all challenges associated with these engines, combustion chamber geometry optimization has demonstrated potential in improving efficiency and reducing pollutant emissions. More notably, integrating multiple optimization techniques appears to offer a more effective pathway toward achieving substantial improvements in overall engine performance.

Abstract

Siombak Lake was formed due to land excavation for the construction of the Belawan - Medan - Tanjung Morawa (BELMERA) toll road, which spans 34 km. Frequent tidal flooding in this lake threatens tourism activities and surrounding settlements, leading to changes in the lake's water environment quality. The water quality of Siombak Lake, as part of water spatial planning, is the subject of this study. Regulation of the Minister of Environment No. 115 of 2003 established the Storet method for this study. The results show that the water in Siombak Lake is brackish and experiences daily tidal fluctuations. The Belawan River, which flows into the Malacca Strait, influences the tides of Siombak Lake. Siombak Lake is an open water body affected by tides. It is saline and has high oxygen levels. The high phosphate levels indicate that these waters are already polluted.

Abstract

A generator is vital for ship operations, serving as a source of electrical power generation on board. The electrical system changing loads every second. Even with these changes, the power demand stays steady and must be supplied correctly. Voltage stability shows how well the system can keep the voltage steady during normal operation or after something goes wrong. Things like added loads or changes in the system setup can also affect this stability. The method used in this research is circuit modeling that conducted using the Electrical Transient Analysis Program (ETAP) software to collect data. This modeling is essential for designing a system that can be effectively simulated. The result is the voltage and frequency stability values while the air compressor motor operates at 4.5kW showed no significant voltage changes. In contrast, when the electric bow thruster motor, operating at 335kW, runs, the voltage dropped to 85% within 6.5 seconds. During a short circuit at the 15th second compartment bus, the engine room bus experiences a voltage dropped of 77%, while the hull compartment bus dropped by 45%. This showed that the system is unsafe for the equipment, as the as a voltage.

Abstract

Collisions of ships to cranes in container terminals are attracting attention from the maritime safety community. This paper provides a berthing safety analysis using the berthing aid and automatic identification systems. First, a berthing aid system is developed to measure berthing safety, as speed and angle indicate. The berthing aid system installed in a berth consists of two laser sensors to measure ships' distances, speed, and heading during the berthing maneuver. Second, a berthing maneuver simulation is conducted to determine tugboat elements, consisting of the number and capacity of tugboats, using a time series of thrust power and direction. The elements are simulated to achieve the berthing safety indicated by the time series of speed over the ground, course over the ground, and the ship's heading angle relative to the berth. The monitoring of ship trajectory using an automatic identification system in the port area and berthing safety parameters along the end stage of the berthing maneuver using the berthing aid system has been implemented in this research. The measurement proved that the berthing maneuvers comply with the requirements.

The purpose of this research is to analyze supply chain risks in the procurement process that affect the delay in ship construction. This research is to complement previous research that has analyzed the Production process. From the research results, the number of risk events can be identified. A questionnaire was prepared to determine the risk weight using the Failure Mode and Effect Analysis (FMEA) method. There are how many risk events with a high Risk Priority Number (RPN) that affect the delay in barge construction. The results showed an assessment score in the form of a Risk Priority Number (RPN) consisting of activities: The calculation of the estimated material list is revised due to the minimum order with a score of 235.98, The length of the engineering evaluation process (Evatek) with a score of 275.99, Shipping Documents are often sent late by importers with a score of 262.00 and material status is still Eigen Loosing with a score of 169.13. Develop a mitigation strategy to prevent the risk from recurring. There are 8 mitigation steps that can be taken based on the results of discussions with expert practitioners in the shipping industry as described in Table 4.17 regarding developing mitigation strategies such as seeking data from manufacturers regarding minimum orders for steel plates and profiles, coordination with suppliers regarding manufacturing data during Engineering evaluation, Shipping and Customs processes and receipt of materials must be faster, so that potential delays to the shipbuilding process can be avoided.

Abstract

Glass fibre vessels in Indonesia, which has thousands of islands, are increasingly used due to their relative low price, light weight, corrosion resistance, and low maintenance costs. However, the aggressive marine environment such as exposure to salt water, ultra violet light, temperature changes, and repeated mechanical loads, affect the service life of this material. Determining the mechanical characteristics of glass fibre vessels is important to prevent structural damage that compromises safety and operations. The purpose of this research is to identify and analyse the condition of shipyards, fibreglass vessels that have been in operation, and examine the mechanical characteristics of glass fibre vessels. The research methods used are literature studies and field surveys to shipyards, glass fibre ships, and testing mechanical characteristics with tensile tests and bending tests. The results obtained from this study are the identification of the condition of the glass fibre shipyard, the condition of the operating glass fibre ship, and the mechanical characteristics of glass fibre ships mostly do not meet the standards of the Indonesian Classification Bureau. Recommendations to improve the quality of production are the location, method, labour, design and materials such as ship resin and laminate layers used during the production process have met and obtained certification set by the Indonesian Classification Bureau.

Abstract

Offshore wind farms are vital in supporting the global energy transition, requiring high structural integrity, particularly in welded T-K-Y joints of jacket foundations. These joints must endure harsh marine environments and dynamic loads, making weld quality a critical factor. This research aims to identify, analyze, and mitigate the risks associated with Flux Cored Arc Welding – Gas Shielded (FCAW-GS) on T-K-Y joints in offshore wind farm jacket construction using the Failure Mode and Effect Analysis (FMEA) method. The study used expert surveys to assess risk factors based on Severity (S), Occurrence (O), and Detection (D), which were quantified into Risk Priority Numbers (RPN). A 5x5 risk matrix was employed for visualization, and mitigation strategies were developed based on the highest RPN values. The most significant risks identified were: inadequate preheating in T-joints (RPN 158.33), poor inter-pass cleanliness in K-joints (RPN 308.00), and similar cleanliness issues in Y-joints (RPN 264.44). After implementing risk mitigation measures such as welder training and strict inter-pass cleaning procedures, the weld rejection rate was reduced to only 1.2% out of 998 joints. The application of FMEA proved effective in prioritizing and controlling welding risks. This structured risk management approach—aligned with ISO 31000:2018—contributed to improved weld quality and reliability in offshore wind farm construction.

Abstract

Rising concerns about energy consumption and the environmental impact of fossil fuels are driving the search for alternative, cleaner energy sources. Extensive research has been conducted to explore alternative fuels as a means of optimizing energy requirements. This review provides a comprehensive analysis of how alternative fuels affect the combustion process in compression ignition (CI) engines, focusing on various combinations of diesel fuel with biodiesel, hydrogen, ammonia, LPG, and CNG. These fuels were combined to determine the most effective option. In the case of biodiesel-hydrogen mixtures, a 13-22% decrease in brake thermal efficiency (BTE) was observed. Conversely, using natural gas as an alternative fuel in dual-fuel engines resulted in a substantial increase in brake specific fuel consumption (BSFC), reaching up to 250 g/kWh.

Abstract

The global need for renewable energy has encouraged the use of biodiesel from organic waste as an alternative to hydro-carbon fuels. This study focuses on evaluating the performance of a CI diesel engine using a fuel blend made from palm oil and banana peel oil. The objective is to determine the optimal blend in terms of fuel properties, engine performance, and exhaust emissions. The biodiesel is produced using the transesterification method for palm oil and a heating extraction process for banana peel oil. Engine tests are carried out on a Yanmar TF85-ME single-cylinder diesel engine using three fuel types: B0 (Dex-lite), BBO-30 (30% banana peel oil and biodiesel), and BBO-50 (50% blend). Fuel characterization showed that BBO-50 had the highest viscosity (4.23 cSt) and density (925 kg/m³), while BBO-30 had the highest calorific value (45.1 MJ/kg). Performance testing revealed that BBO-30 achieved the highest torque (7.26 Nm), lowest SFC (367.4 g/kWh), and highest thermal efficiency (22.4%). Emission tests showed that BBO-50 produced the lowest CO and NOx emissions, while BBO-30 had the highest CO2 emis-sion, indicating more complete combustion. Based on these results, BBO-30 is recommended for optimal engine efficiency, while BBO-50 is more suitable for lower emissions.
