Abstract

Marine biofouling — the progressive accumulation of microorganisms, algae, barnacles, and other aquatic organisms on submerged vessel hull surfaces — imposes a 25–40% fuel consumption penalty at the macrofouling stage and simultaneously facilitates the transport of non-indigenous invasive species across biogeographic barriers, constituting both a significant GHG emission driver and a global ecological threat. This study examines antifouling coating technology adoption and compliance in the Indonesian domestic fleet, evaluates alternative antifouling technologies against environmental performance, fuel saving benefit, and IMO regulatory compliance dimensions under Indonesian tropical operating conditions, and develops prioritized technology adoption and regulatory implementation recommendations. A mixed-methods design was employed, combining hull inspection and documentary review of 84 domestic vessels across four vessel type categories at three Indonesian port areas, stakeholder interviews with 46 participants across operator, shipyard, regulatory, industry, and NGO groups, and comparative technology performance assessment of four antifouling system categories. Results reveal that while 86% of vessels achieve AFS Convention (TBT prohibition) compliance, only 6.5% fully comply with IMO Biofouling Management Guidelines. A full fleet eco-upgrade across the 84-vessel sample would deliver annual fuel savings of 12,980 tonnes HFO and 40,500 tonnes CO₂ at a positive 15-year fleet NPV of USD 16.6 million. Cost barriers — with eco-friendly coatings carrying a 2–4× unit price premium — are identified as the primary adoption constraint. Three priority policy recommendations are proposed: mandatory Biofouling Management Plan documentation for all vessels exceeding 400 GT; a green maritime financing facility for eco-coating upgrades during drydocking; and mandatory hull fouling performance reporting within the CII monitoring framework.

Abstract

The role of short sea shipping in regional logistics operations is very important. With pressures from IMO regulations (EEXI and CII) growing, the maritime industry must adopt more efficient propulsion. The impact of marine technology choice on the shipping industry and its effect on the entire economy is often overlooked by society. In this paper, a techno-economic and environmental comparison of three propulsion architectures for a 5000 GT Ro-Ro passenger ferry is presented. These architectures include conventional diesel-mechanical (DM), diesel-electric (DE), and parallel hybrid (PH). The project developed a simulation framework leveraging operational profiles that were obtained from Automatic Identification System (AIS) data through the national AIS archive Marine Cadastre. The fuel consumption, emissions (CO₂, NOₓ, and SOₓ), and life-cycle cost (LCC) of all three systems were evaluated over a 20-year planning horizon. The findings demonstrate that PH approach is responsible for a 25.0% decline in yearly fuel consumption and CO₂ emission as compared to DM baseline and 14.3% compared to DE system. While the PH system necessitates 31% more CAPEX than the DM system, its payback period is approximately 2.15 years because of significant savings on operating cost. This framework, combining quantitative evidence and systematic decision-making processes, will help ship owners and other policy makers choose the best propulsion technologies to decarbonise short-sea shipping fleets.

Abstract

This study examines the social and economic conditions of octopus handline fishers in Gampong Lamteungoh, Aceh Besar. The research was motivated by declining catch production, which potentially affects fishers’ household welfare. The study aims to describe social conditions and analyze economic conditions based on income levels. Data were collected in April 2025 using a census method involving 30 fishers through observation, interviews, and documentation. Social conditions were analyzed descriptively using welfare indicators from Statistics Indonesia (BPS), while economic conditions were analyzed using income analysis. The results show that 97% of fishers have high social welfare and 3% moderate welfare, based on housing, education, and access to basic services. However, economically, fishers remain vulnerable, with an average income of IDR 1,909,365 per month, which is below the regional minimum wage. High household expenditures and declining catches contribute to this condition. The study highlights the need for improved fisheries management and economic support for small scale fishers.

Abstract

Accurate standing-height measurement is fundamental to ergonomic assessment, informing workstation design, equipment fit, and occupational health surveillance. Manual Anthropometer, while considered a reference standard, is susceptible to operator-dependent variability, transcription errors, and procedural inefficiency. This study aimed to design, develop, and rigorously validate a sensor-based digital standing-height measurement system by comparing its performance against a calibrated manual anthropometer. A randomized crossover experimental design was employed with 50 healthy adult participants. Primary outcomes included measurement agreement assessed via Bland-Altman analysis (95% Limits of Agreement threshold: ±0.5 cm), test-retest reliability evaluated using Intraclass Correlation Coefficient (ICC 2,1), time efficiency, and user acceptance. Bland-Altman analysis revealed a negligible mean bias of [-0.1] cm with 95% LoA ranging from [-0.8] cm to [0.6] cm, confirming non-inferior accuracy. The digital system demonstrated excellent test-retest reliability (ICC = 0.90), surpassing that of the manual method (ICC = 0.75). Measurement time was reduced by 64.7% (p < 0.001; Cohen's d = 33.50). Ninety percent of participants preferred the digital system. The sensor-based digital anthropometer provides a valid, reliable, and highly efficient alternative to manual standing-height measurement, supporting its potential application in occupational health surveillance and ergonomic assessment.

Abstract

Marine tourism development requires accurate information regarding marine environmental conditions and navigational safety. However, many coastal tourism areas in Indonesia still rely on conventional observation methods that are limited, fragmented, and difficult to access in real time. This study aims to develop a clean energy-based information system capable of mapping marine environmental conditions and supporting navigational safety for sustainable marine tourism. The system integrates environmental sensors, Global Positioning System (GPS), Geographic Information System (GIS), and renewable energy sources through solar-powered monitoring stations. The research employed a Research and Development (R&D) method consisting of needs analysis, system design, prototype development, implementation, and evaluation. Data were collected from temperature, salinity, wave height, wind speed, water level, and vessel route monitoring. The resulting system provides spatial visualization, hazard alerts, route recommendations, and environmental status information through a web-based dashboard. The implementation results indicate that the system can improve the effectiveness of marine environmental monitoring and increase navigation safety in tourism areas. Furthermore, the use of solar energy supports sustainable operation in remote coastal locations with limited electricity access.

Abstract

Indonesian fishing communities possess unique social characteristics due to their dependence on the sea as their primary source of livelihood. Despite abundant coastal and marine resources, fishers often remain trapped in cycles of structural poverty. The primary factors contributing to this include limited human resource quality, restricted access to technology, and limited market and capital control. Fishermen face low income due to challenges in employment relationships because the fishermen’s social dependence on ship owners, which results in unilateral control over market access and selling prices. Additionally, issues persist regarding competency enhancement, occupational safety, and facility support. This study aims to identify social behaviors that require intervention to improve social norms in the working relationships between ship owners and fishermen in Kupang City. Employing a soft systems methodology, the research identifies social issues necessitating intervention in the interaction patterns among fishermen, ship owners, and other stakeholders. The study yields three root definitions. First, local governments, fishing ports, along with ship owners are creating a competency improvement program for fishermen, through the implementation of independent training to achieve enhanced skills, workplace safety, and professionalism of fisheries human resources. Second, the local government, ship owners and fishermen's organizations, established a mediation and labor relations management system through a fair profit-sharing mechanism and clear work regulations. Third, local governments, fishermen's organizations and related institutions, are designing a system of protection and independence for fishermen through strengthening market access, financial management, and alternative livelihoods, to improve welfare and reduce vulnerability.

Abstract

Energy inefficiency in marine diesel engines remains a significant challenge due to substantial waste heat losses. This study aims to evaluate the thermodynamic performance of a Kalina cycle for waste heat recovery from a low-speed marine diesel engine under varying operating temperature and ammonia-H2O compositions. A thermodynamic model is developed based on mass and energy balance principles to analyze system behavior across different conditions. The analysis focuses on key performance aspects, including evaporator heat input (Qin), pump work, expander work, thermal efficiency, and energy losses for ammonia concentrations of 30%, 45%, and 60%. The results show that increasing ammonia concentration significantly reduces the required heat input, while expander work decreases with rising condenser temperature due to a reduced enthalpy drop. Thermal efficiency is found to decrease with increasing evaporator temperature, as additional heat input is not effectively converted into useful work, leading to higher irreversibility. The highest efficiency of 11.9% is achieved at 60% ammonia concentration under lower temperature conditions. In contrast, energy losses increase consistently with higher heat input, particularly at elevated temperatures. Overall, the findings demonstrate that optimal system performance depends on a balanced combination of operating temperatures and working fluid composition.

Abstract

Ocean observation increasingly relies on Unmanned Surface Vehicles (USVs) for wide-area maritime data collection, yet existing Ground Control Station (GCS) systems remain limited by desktop-based accessibility constraints, high-latency HTTP communication, unoptimized relational databases, and the absence of integrated oceanographic sensor visualization. This study aims to design and develop a web-based GCS that unifies telemetry monitoring, bidirectional remote control, CTD and ADCP sensor visualization, and waypoint-based mission planning within a single browser-based interface. The system was developed using the Rapid Application Development (RAD) methodology, with MQTT and WebSocket adopted for low-latency communication and PostgreSQL with TimescaleDB for time-series data management. Functional testing confirmed that all core features operated correctly. Performance evaluation under 4G-LTE field conditions showed an average command round-trip latency of 178 ms and end-to-end monitoring latency below 250 ms. TimescaleDB hypertable conversion improved write throughput by 2.5×, reduced long-range query latency by 3.75×, and achieved a storage compression ratio of 875×. The proposed architecture provides a replicable reference for web-based USV GCS development across ocean observation applications.

Abstract

Engine room fire remains one of the most critical threats to ship safety because it involves the interaction of fuel systems, lubrication systems, hot surfaces, electrical installations, confined-space operations, and emergency response constraints. Although international regulations such as SOLAS, STCW, and IMO Model Courses have established a comprehensive normative framework, fire incidents in ship engine rooms continue to occur. This condition indicates a persistent gap between regulatory standards, technological capability, and operational implementation onboard. Previous studies have examined engine room fire from different perspectives, including technical failure, fire detection, suppression systems, human factors, and safety barriers. However, most of these studies remain fragmented and do not sufficiently explain how technical readiness, managerial implementation, and human capability interact in real ship operations. This article aims to develop an integrated fire safety model for ship engine rooms by synthesizing those three dimensions into one analytical framework. The study applies an integrative literature review and conceptual model development approach based on maritime safety regulations, peer-reviewed maritime fire studies, and organizational safety theory. The results show that effective fire prevention and response depend on the simultaneous strength of technical systems, procedural discipline, and crew capability. The proposed model offers practical implications for shipping companies, maritime education institutions, and safety regulators in strengthening evidence-based fire safety in commercial vessels.

Abstract

Marine conservation areas in small island environments require compatibility between management zoning and local physical oceanographic conditions to function effectively and sustainably. Gili Ketapang, located in the Madura Strait, has been designated as a Marine Conservation Area under the Decree of the Minister of Maritime Affairs and Fisheries No. 64/KEPMEN-KP/2020. However, evaluations of zoning suitability based on physical oceanographic characteristics remain limited. This study aims to assess the suitability of zoning within the Gili Ketapang Marine Conservation Area using key physical oceanographic parameters, including currents, waves, tides, and wind. Tidal analysis was conducted using the Admiralty method to determine tidal type and sea level characteristics. Wave and current data were obtained from Copernicus Marine Reanalysis with a 3-hour temporal resolution over a ten-year period, while wind data were used to support seasonal analysis. Zoning suitability was evaluated by comparing the analyzed oceanographic conditions with relevant criteria for coastal and marine utilization. The results indicate that the waters of Gili Ketapang are characterized by a mixed, mainly semidiurnal tidal regime, with a Formzahl value of 1.3. Seasonal variability in currents and wave conditions reveals periods that are less favorable for utilization activities in certain sub-zones, particularly within the Aquaculture Sub-Zone. These findings suggest that zoning suitability is dynamic and strongly influenced by seasonal oceanographic variability. This study highlights the importance of integrating long-term physical oceanographic analysis into the evaluation and management of marine conservation zoning, especially in small island environments with high hydrodynamic dynamics.
