Abstract

Hatch covers are critical structural components that maintain cargo hold watertightness and operational safety. This study investigates non-conformities in the compression bar of a manual pontoon-type hatch cover on a Gearless Multi-Purpose Vessel constructed at PT. KTU Shipyard. The analysis evaluates construction conditions and the conformity of fabrication and installation processes with MacGregor standards and ClassNK requirements. Root causes were identified using the Root Cause Analysis (RCA) method within a qualitative descriptive case study approach. Data were obtained through visual inspection, manual measurement with an acceptable compression tolerance of 14–24 mm, ultrasonic testing with a leak acceptance limit of <10% OHV, and review of design drawings and technical specifications. RCA was performed using fishbone diagrams and the five-why method, addressing human, method, material, measurement, environment, and machine factors. Findings show that improper installation beyond manufacturer tolerances caused uneven gasket contact pressure, reducing sealing performance. The primary causes were inadequate fabrication and installation practices and inconsistent tolerance verification. Recommended corrective actions include standardizing procedures, strengthening technical competence, and implementing systematic inspection and measurement control at all work stages.

Abstract

The majority of fishermen in Indonesia, approximately 95.6% are small-scale fishermen who operate daily using small vessels powered by outboard engines. This reliance on fossil fuels and the environmental impact, including air and noise pollution, highlights the need for more sustainable alternatives such as electric motors. This study aims to design an electric propulsion system for small fishing vessels by adapting electric motors commonly used in electric scooters and evaluating their initial performance. The performance test was conducted to assess the system's feasibility and to estimate energy requirements and optimal battery capacity. The results indicate that electric motors can be utilized as a propulsion system with essential components including a dynamo, battery, controller, shaft, and propeller, reaching Technology Readiness Level (TRL) 2. The initial performance is not yet optimal and requires further refinement of components. The estimated energy requirement is 282.24 Wh, with a recommended battery specification of 24 V 12 Ah for further testing.

Abstract

this paper investigates how human factor variables determine ship accident risk in Indonesian domestic shipping. Drawing on accident investigation reports and international literature, the study proposes and tests a structural model linking deck crew competence, supervisory quality, and work stress to perceived ship accident risk, with safety culture as an intervening variable and work stress and competence as moderators. National data from Indonesia’s National Transportation Safety Committee (KNKT) for 2020–2025 indicate that human error remains the dominant contributing factor in marine accidents, with high fatality rates despite the implementation of SOLAS, STCW, and the ISM Code. Relevant studies confirm that inadequate training, fatigue, miscommunication, and weak supervision are among the most critical contributors to marine casualties. A quantitative survey will be conducted among Indonesian seafarers working on domestic Roro ferries and passenger/ cargo vessels, focusing on major inter-island routes. The proposal model will be tested using Partial Least Square–Structure Equation Modelling (SEM) to assess direct, indirect, and moderating effects of competence and job stress on the relationship between safety culture and perceived accident risk. The expected contribution is twofold: theoretically, it integrates Human Factor Analysis and Classification System (HFACS) Maritime and safety culture perspectives into a comprehensive human factor risk perception framework tailored to an archipelagic developing country; practically, it provides evidence=based insights for regulators and shipping companies regarding priority interventions in crew training, work-rest scheduling, supervision, and safety culture development.

Abstract

This study examines the effect of shipyard layout on sustainability performance based on the Triple Bottom Line, with operational efficiency as a mediator. The main issue is a layout that evolves without integrated planning, reducing material flow efficiency and operational performance. The method used is Structural Equation Modeling–Partial Least Squares (SEM-PLS) based on questionnaire data with purposive sampling. The results indicate that layout has a significant effect on sustainability performance, both directly and through operational efficiency as a key mediator. These findings confirm that layout optimization not only enhances efficiency but also improves environmental and social performance. This study positions layout as a strategic determinant in a sustainable production system.

Abstract

Efficient identification of potential fishing zones is crucial for sustainable coastal fisheries. This study presents the integration of oceanographic data analysis, spatial modeling, and Augmented Reality (AR) technology to predict and visualize suitable fishing locations for Euthynnus affinis in the waters of Panjang Island, Banten, Indonesia. Sea surface temperature (SST) and chlorophyll-a concentrations were derived from MODIS satellite imagery and processed using Google Colaboratory to generate spatial distribution maps of key environmental parameters. These maps formed the basis for predicting potential fishing zones, which were implemented in NaviAR, a WebGIS-based platform with AR features that provides interactive visualization, real-time coordinates, distance measurements, and directional markers toward predicted fishing locations. The system’s main features, including the Home page, AR Camera, and WebGIS modules, were tested using black-box testing, achieving a 100% functional success rate. These results indicate that NaviAR effectively supports decision-making for fishermen by providing spatially explicit and actionable information on potential fishing zones

Abstract

River transportation in Sungai Jeneberang plays a vital role in supporting daily mobility between Kabupaten Gowa and Kota Makassar. However, the existing traditional vessels (katinting) exhibit low safety standards due to poor stability and the absence of adequate safety equipment. This study aims to optimize the design of a modern catamaran based on dynamic stability criteria to improve river transport safety. The research applies a Parent Design Approach combined with geometric modeling using AutoCAD and stability analysis using Maxsurf. The design process is based on field data and evaluated under three loading conditions: lightship, half load, and full load. The resulting principal dimensions are LOA = 12,00 m, B = 5,00 m, T = 0,55 m, with ratios L/B = 2,4, B/T = 9,09, and H/T = 2,91, indicating favorable stability characteristics. The results show that all loading conditions meet the IMO Intact Stability Code (IS Code) requirements, with positive metacentric height (GM) and stable righting arm (GZ) curves. The final 3D design accommodates 20 passengers, 15 motorcycles, and safety equipment, ensuring improved operational safety and comfort. This study contributes to the development of small-scale river transport design by integrating empirical data with stability-based optimization, offering a practical and safer alternative for sustainable river transportation systems.

Abstract

Bilge keels are commonly installed on fishing vessels to improve stability and operational safety; however, their influence on calm water resistance remains insufficiently documented for hull forms representative of Indonesian fishing vessels. This study investigates the effect of bilge keel installation on the total resistance of a 33.5 m tuna longline fishing vessel reconstructed from field survey data in Benoa, Bali. The resistance performance of bar  hull and bilge keel equipped configurations was evaluated using steady state CFD based on the RANS equations and validated against towing tank data at 3, 6, and 9 kn. Simulations were conducted over a range of Froude numbers from 0.09 to 0.271. Results indicate that both configurations exhibit the expected non-linear increase in resistance with speed. Under the investigated numerical conditions, the bilge keel equipped hull was predicted to produce lower total resistance than the bare hull across the evaluated speed range, with the largest reduction of approximately 18% at 6 kn. These findings suggest that, for the investigated hull and appendage arrangement, bilge keel installation may induce favorable local hydrodynamic interactions that partially offset appendage related drag.

Abstract

Indonesia, as a signatory to MARPOL 73/78, holds binding international obligations for vessel-source pollution prevention across all six annexes. Port State Control (PSC) is the primary enforcement mechanism for realizing these obligations operationally, yet evidence consistently indicates a wide and persistent gap between regulatory obligation and enforcement practice. This study provides a systematic assessment of marine pollution prevention policy and PSC enforcement in Indonesia through a mixed-methods methodology combining quantitative benchmarking of 4,218 IOMOU PSC inspection records (2019–2024), 44 semi-structured stakeholder interviews, and comparative regulatory framework analysis. Results reveal that Indonesia's PSC performance falls significantly below both IOMOU regional and Paris MoU benchmarks across all key indicators: the detention rate of 4.8% is double the Paris MoU average, mean deficiencies per inspection exceed the Paris MoU figure by 1.97, and a repeat deficiency rate of 38.4% — 23.6 percentage points above the Paris MoU — confirms that enforcement is not generating the corrective response it should. MARPOL Annex IV (sewage) and Annex I (oil) deficiency gaps against Paris MoU benchmarks reach 13.2 and 10.8 percentage points respectively, both classified as critical. Six primary implementation gaps are identified: PSC officer capacity deficit, absence of digital inspection systems, inter-agency coordination failure, inadequate penalties, domestic fleet MARPOL exemptions, and port reception facility insufficiency. An Integrated Marine Pollution Prevention Reform Framework addressing all six gaps through a phased four-pillar architecture is proposed, offering a structured pathway for Indonesia to close its enforcement deficit and fulfill its international maritime environmental obligations.

Abstract

Marine engineering is undergoing a fundamental redefinition — from a discipline optimized primarily for propulsive performance and fuel economy to one in which environmental engineering is integral to every shipboard system domain. This study develops an Integrated Environmental Engineering Framework (IEEF) for Indonesian domestic vessel operations, synthesizing marine engineering innovation literature across propulsion, thermal management, exhaust treatment, waste management, and hull systems into a structured, evidence-based environmental technology portfolio. A mixed-methods methodology was employed, combining quantitative Environmental Engineering Audit Protocol (EEAP) assessment of 72 Indonesian domestic vessels across 10 MARPOL-relevant engineering domains with AHP-TOPSIS multi-criteria technology assessment involving 24 domain experts. The audit reveals critical compliance gaps in CII monitoring systems (36%), waste heat recovery installation (10%), and eco-compliant antifouling coatings (35%), alongside high-severity deficits in NOₓ treatment (42%), sewage treatment (44%), and ballast water management (50%). AHP-TOPSIS ranking identifies waste heat recovery and CII digital monitoring as equal top-priority investments (composite score 0.83), followed by nano-hybrid antifouling (0.79), Annex IV sewage treatment (0.77), SCR/EGR NOₓ reduction (0.72), and LNG dual-fuel conversion (0.68). The IEEF organizes these priorities within a three-horizon implementation roadmap — Horizon 1 (2025–2027) deploying proven compliance technologies, Horizon 2 (2027–2032) advancing NOₓ reduction and hybrid system integration, and Horizon 3 (2032–2050) transitioning toward hydrogen, ammonia, fuel cell propulsion, and on-board carbon capture — providing a structured engineering trajectory aligned with IMO 2050 net-zero ambition.

Abstract

Indonesia's position as the world's largest archipelagic state — operating domestic shipping networks through the globally significant Coral Triangle and other ecologically sensitive marine environments — creates one of the world's most consequential maritime pollution risk landscapes. This study conducts a comprehensive environmental risk assessment of fuel oil spill incidents in Indonesian archipelagic waters, integrating accident probability modelling, ecosystem vulnerability mapping, and response capacity analysis into a spatially explicit Integrated Spill Risk Index. A mixed-methods methodology was applied, combining negative binomial regression analysis of 1,847 domestic shipping incident records (2015–2024) with AIS traffic exposure data across six geographic zones, composite marine environmental sensitivity mapping from Allen Coral Atlas, Global Mangrove Watch, and BPS Indonesia livelihood data, NOAA GNOME drift trajectory modelling, and stakeholder interviews with 28 maritime safety and environmental stakeholders. Results identify the Makassar Strait (risk index 0.89) and Banda Sea (0.84) as Critical priority zones requiring immediate investment. Despite having lower incident probability, the Banda Sea registers the highest environmental vulnerability score (0.96) due to its Coral Triangle location, extensive seagrass and mangrove coverage, and coastal communities with over 80% fish dependency. Three immediate priority recommendations emerge: establishment of dedicated OSRO pre-positioning at Makassar Port and Ambon; mandatory AIS-based vessel traffic management with speed restrictions through ecologically sensitive Makassar Strait segments; and strengthened SMS verification and P&I insurance requirements for domestic tankers and bulk carriers operating Critical-zone corridors. The study provides the first integrated spill risk index for Indonesian domestic shipping routes, offering a prioritization framework for the Ministry of Transportation, KPLP, and environmental authorities.
