Abstract

Tuna fishing not only generates significant economic profit, but also has negative environmental impacts due to the intensive use of materials, equipment, and energy. This study aims to identify and measure the input and output components of the tuna fishing process using longline vessels at the Cilacap Oceanic Fisheries Port through a life cycle inventory (LCI) approach. Data collection was carried out through field observations and structured interviews with 30 selected stakeholders, including the analysis of vessel specifications, fishing gear, and supplies. The results of the study show that supplies dominate operational inputs with a total mass of 62,026 kg/year. This indicates a high resource intensity, requiring 29.31 kg of material  input to produce 1 kg of tuna. In addition, this activity produces outputs in the form of significant environmental impacts, including Sulfur Oxide (SOx) emissions of 707.62 kg/year due to diesel fuel combustion and solid waste of 33,550 kg/year, predominantly consisting of single-use plastic packaging from leftover supplies. These findings indicate the need for improvements in logistics components from the upstream side and waste management strategies in the fisheries sector.

Abstract

Biofouling is a collection of unwanted living organisms on surfaces submerged in water. Biofouling is a complex occurrence caused by various physical and environmental factors that can be overcome by regular hull cleaning. The main purpose of underwater hull cleaning is to remove dirt and restore propulsion efficiency. Another benefit of hull cleaning against biofouling is to restore or rejuvenate the effectiveness of antifouling paint. This study aims to determine the extent of the effect of periodic underwater hull cleaning, with results used to determine the most efficient time interval for performing periodic hull cleaning and the percentage of fuel that can be saved by performing periodic underwater cleaning. The methods used in this study included identifying biofouling growth through flat-plate experiments immersed in the waters of the Madura Strait and modeling surface roughness growth using regression simulations based on Computational Fluid Dynamics (CFD) on a three-dimensional tanker model. Simulations were conducted with speed variations of 10, 12, 14, and 16 knots, and biofouling growth periods of 7, 12, 18, and 24 months. The study's results show that biofouling increases ship resistance by an average of 2-3% per month compared to ships with clean hulls. Analysis of underwater hull-cleaning scenarios shows that cleaning at 18 months results in the lowest fuel consumption across all speed variations tested. At a speed of 10 knots, fuel savings reached 5.7% or 54.93 tons, at 12 knots 3.3% or 59.65 tons, at 14 knots 2.7% or 101.76 tons, and at 16 knots 9.3% or 1421.21 tons compared to ships without hull cleaning. In conclusion, the most efficient underwater hull cleaning period is every 18 months after sailing.

Abstract

Propeller blade geometry, particularly the camber ratio, plays a critical role in determining hydrodynamic behavior and fuel consumption in marine propulsion systems. This study investigates the influence of camber ratio variation on the performance of a Gawn Series propeller by applying an Engine–Propeller Matching (EPM) approach. Open-water performance characteristics, including thrust coefficient (KT), torque coefficient (KQ), and open-water efficiency (η₀), were obtained through Computational Fluid Dynamics (CFD) simulations for four camber configurations of 0%, 1%, 1.5%. The numerical model was validated using resistance and open-water test data, yielding deviations below 5% and 3%, respectively, which confirms the reliability of the simulation results. The analysis shows that higher camber ratios generally increase thrust and torque as a result of strengthened pressure gradients and enhanced flow acceleration along the suction side of the blade, with the 1% camber configuration demonstrating the highest efficiency at J = 0.9 (η₀ = 0.596), representing a 3.85% improvement over the baseline. Matching the resulting propeller load curves with the performance envelope of a 2 × 3900 kW engine setup provides insight into optimal operating conditions and specific fuel consumption across the vessel’s working speed range. The 1% camber variant consistently delivers better fuel economy, maintaining safe operating points. Overall, these results underscore the substantive influence of camber modification on propeller hydrodynamics and propulsion efficiency, identifying the 1% camber configuration as the most suitable option for 60-m high-speed vessels based on combined hydrodynamic, fuel, and operational criteria within the EPM framework.

Abstract

This study investigates the combustion characteristics, engine performance, and emission behavior of an ammonia–biodiesel (NH₃–B100) dual-fuel compression-ignition engine based on a Yanmar TF-85 diesel platform using a combined experimental and numerical approach. Three-dimensional (3D) in-cylinder combustion simulations were performed using ANSYS Forte, while overall engine performance was evaluated through a one-way 3D-1D coupling framework integrated with MATLAB. Baseline single-fuel B100 operation was first validated against experimental measurements, yielding prediction errors below [6%] for engine power, confirming the reliability of the simulation model. After validation, ammonia was introduced through intake manifold injection to establish dual-fuel operation. The results indicate that ammonia substitution delays combustion phasing and reduces the peak heat release rate by approximately [22%], leading to decreases in indicated mean effective pressure and brake power of [30%] and an increase in specific fuel consumption of [30%]. In terms of emissions, carbon-related species were reduced, with CO₂ and CO decreasing by up to [60%] and [50%], respectively, whereas NOₓ emissions increased by [20%], and measurable NH₃ slip was observed under high ammonia energy fractions. Overall, the proposed 3D–1D modeling framework provides an accurate and computationally efficient tool for evaluating ammonia–biodiesel dual-fuel strategies and supports the development of low-carbon marine diesel engines.

Abstract

In the current industrial era, work intensity will increase along with consumer demand. As a result, the workload received by workers must be considered, regardless of whether it is a low, medium, or high workload. The focus of this study is on the workload borne by workers who work in the wooden ship manufacturing industry at a company that produces wood as the main material for making wooden ships. Lifting, cutting, and assembling are jobs that are often done in the production section, which require many repetitions and long times. Therefore, it can be concluded that these activities have a very high risk and have a dangerous impact on workers to experience muscle or bone injuries. The Nordic Body Map (NBM) questionnaire was used to conduct an initial measurement of the workload risk received by workers to determine the risk of workload received. The results showed a high value for complaints of Musculoskeletal Disorders (MSDs). Furthermore, further measurements of ergonomic risks were carried out using the Rapid Entire Body Assessment (REBA) method , so that design steps can be taken to improve work posture using the CATIA application to reduce the level of complaints that occur.

Abstract

The availability of safe and sustainable drinking water is a vital necessity for boarding educational institutions. Madrasah Aliyah Negeri Insan Cendekia (MAN IC) Paser faces limitations in the quantity and continuity of clean water supply from external providers, while at the same time possessing a potential surface water source in the form of a lake with a large storage volume. However, the quality of the lake water does not yet meet drinking water standards, as indicated by high turbidity levels and potential microbiological contamination. This study aims to analysis of investment of the design a lake water treatment system into drinking water that complies with the Indonesian Ministry of Health Regulation No. 492 of 2010, as well as to design an efficient and sustainable water management supply chain and ecosystem. The research methods include raw water quality analysis, jar test experiments using several types of coagulants, the design of a water treatment plant (WTP) employing a conventional treatment system, and supply chain analysis based on a systems thinking approach. The results show that a complete water treatment system consisting of presedimentation, coagulation–flocculation, sedimentation, filtration, and disinfection is able to reduce turbidity to meet drinking water quality standards. In addition, the integrated supply chain design supports the operational sustainability of drinking water provision within the MAN IC Paser environment. This study is expected to serve as a model for drinking water self-sufficiency based on local resources in educational institutions.

Abstract

Risk assessment of Energy Storage Systems (ESS) in ships is a fundamental requirement to ensure operational safety in the maritime sector. This study investigates risk analysis and mitigation strategies for a Hybrid Energy Storage System (HESS) applied to a 11-meter fully-electric Seabus, configured with Lithium Iron Phosphate (LFP) and Lithium Titanate Oxide (LTO). The Hazard Identification (HAZID) method is employed to systematically identify potential hazards during operation, covering technical, operational, and environmental aspects. The findings reveal that hazards with the highest risk ranking include explosion and battery fire, both of which pose severe threats to vessel safety and environmental integrity. To address these critical risks, appropriate mitigation strategies are proposed, including advanced battery management systems, physical protection of critical components, and emergency operational procedures tailored to maritime safety standards. This research highlights the importance of integrating HAZID into the design and operation of HESS to enhance reliability and safety

Abstract

Maritime transportation plays a vital role in supporting economic activities and regional connectivity in archipelagic countries such as Indonesia yet ship accidents remain a persistent safety concern particularly when they result in loss of life. This study aims to develop a severity oriented risk assessment model for ship accidents by integrating accident categories and fatality factors using Fault Tree Analysis. The study focuses on identifying dominant causal pathways and critical contributing factors that lead to fatal ship accidents rather than merely examining accident frequency. The research adopts a quantitative analytical design using secondary data obtained from 50 officially documented ship accident cases involving fatalities in Indonesian waters between 2017 and 2022. The dataset includes detailed information on accident categories vessel characteristics and causes of death with a total of 295 recorded fatalities. Fault Tree Analysis is applied to structure the causal relationships between basic events intermediate accident categories and the top event defined as a fatal ship accident. Qualitative analysis is conducted to identify dominant failure pathways and minimal cut sets while quantitative analysis estimates the probability contribution of each basic event based on historical fatality data. The results indicate that sinking and fire accidents are the most critical intermediate events accounting for more than three quarters of total fatalities. At the basic event level human related factors dominate fatal outcomes particularly insufficient access to life saving appliances and ineffective emergency response which together contribute more than half of all fatalities. Technical factors such as fire system failure and toxic gas exposure represent the second most significant contributors while environmental and external factors mainly act as amplifiers that reduce survivability after an accident occurs. The integrated qualitative and quantitative analysis reveals that fatal ship accidents are largely driven by dominant high impact basic events rather than complex combinations of multiple low probability failures. This study contributes to maritime safety research by providing an empirically grounded Fault Tree Analysis model that explicitly links accident categories with fatality mechanisms. The findings offer practical implications for risk based maritime safety management by prioritizing human centered interventions emergency preparedness and fire safety systems. The proposed model provides a robust analytical foundation for policy formulation targeted risk mitigation and future development of life safety oriented maritime risk assessment frameworks.
