Abstract

Abstract¾ The increasing production of fiberglass reinforced plastic (FRP) vessels in traditional shipyards contributes to higher waste generation. The lack of information regarding the quantity and characteristics of this waste makes it difficult to assess the sustainability of recycling FRP waste into composite boards. This study aims to estimate FRP waste based on vessel GT size and identify the physical forms of waste produced during the manufacturing process at the CV. Roni Marine Shipyard, Cilacap. The method used includes direct observation, vessel sampling by size, and classification and weighing of waste based on its type/shape. Results show that FRP composite waste in sheet/plate form accounts for the highest percentage (67%), followed by purse solid FRP composite waste (30%), and impure solid FRP composite waste (3%). The average amount of FRP waste generated per 1 Gross Tonnage (GT) of a vessel is 2.73 kg/GT. The highest amount of waste was produced during the frame installation stage. These findings are important for improving waste management efficiency and supporting the recycling of FRP waste into value-added products such as composite boards.

Abstract

Abandoned, Lost, or Discarded Fishing Gear (ALDFG), or ghost gear, poses a major threat to marine ecosystems and the sustainability of fisheries. This study in Pangandaran, Indonesia, estimated gillnet losses, identified key causal factors, and developed management recommendations. Data was collected through field observations and structured interviews with 90 gillnet fishers at Cikidang Fishing Port (PP), analyzed using Confidence Intervals (CI) to estimate annual losses. All respondents reported ALDFG incidents, with losses ranging from 16,473–19,648 pieces (752,528–897,605 meters) per year, equivalent to IDR 8.66–10.33 billion. The main causes included strong currents, snagging on coral reefs, and adverse weather. ALDFG not only drives ghost fishing but also degrades marine habitats and imposes economic burdens on fishers. Recommended mitigation measures include awareness programs, adoption of modern technologies (GPS, RFID, AIS), gear marking, planning of fishing grounds, skill enhancement, use of durable materials, avoiding gillnet deployment in high-risk areas, lost gear reporting systems, onshore facilities for storing end-of-life fishing gear (EOLFG) and ALDFG, providing incentives to support these interventions, and circular economy practices. This study provides critical local quantitative data and causal analysis to inform management strategies and policy interventions to reduce ALDFG at the local level.

Abstract

This research aims to analyze occupational accident risks at PT. Blambangan Bahari Shipyard using the Failure Mode and Effect Analysis (FMEA) method and to formulate risk control recommendations based on ISO 45001:2018 and the 5S concept. The research focused on the fabrication and sub-assembly workshops, which involve intensive production activities and significant occupational hazards. Data were collected through direct observation, interviews, and questionnaires distributed to workers. Risk assessment was conducted using the FMEA parameters of Severity (S), Occurrence (O), and Detection (D), which were used to calculate the Risk Priority Number (RPN) and determine risk priorities. The results identified 40 potential hazards, consisting of 30 low-risk, 2 medium-risk, and 8 high-risk categories. The dominant hazards were associated with the repetitive use of electrical tools, exposure to fiberglass dust, workplace noise, welding activities, and electrical hazards. Based on these findings, risk control recommendations were formulated by applying the ISO 45001:2018 hierarchy of controls and supported by the implementation of the 5S (Seiri, Seiton, Seiso, Seiketsu, Shitsuke) concept through improved work discipline, proper use of personal protective equipment, workplace organization, and housekeeping practices. The proposed recommendations are expected to minimize occupational accident risks and contribute to the development of a safer, cleaner, and more organized working environment.

Abstract

The performance of Autonomous Underwater Vehicle (AUV) waterjet propulsion systems is highly dependent on nozzle geometry and environmental back pressure. Therefore, this study aims to analyze the effects of nozzle length, length-to-diameter (l/d) ratio, and back pressure on thrust, velocity, flow coefficient, and hydraulic loss. The study was conducted using Computational Fluid Dynamics (CFD) simulations. Three nozzle geometries (Cos, Conical, and Exponent) were evaluated at lengths of 40, 60, and 90 mm. The optimal geometry was then analyzed by varying the l/d ratio (1, 1/2, 1/3, and 1/4) under back pressure conditions from 0 to 1 MPa. The results indicate that the Cos nozzle with a 90 mm length yields the highest thrust and velocity. Furthermore, an l/d ratio of 1/3 demonstrates the optimal performance, achieving a near-ideal flow coefficient (0.999) and minimal hydraulic loss, particularly under low back pressure conditions. Ultimately, a Cos nozzle with a 90 mm length and an l/d ratio of 1/3 is highly recommended to maximize the propulsion efficiency of AUVs.

Abstract

Squid fishing fleets are among the major contributors to carbon emissions in the marine fisheries sector due to their high energy demands during at-sea operations. This study aimed to compare the Fuel Use Intensity (FUI) and carbon footprint of squid fishing fleets using Squid Jig and Bouke Ami (Lift Net) gear operating at the Nizam Zachman Ocean Fishing Port in Jakarta. The study was conducted from April to May 2026 using operational data collected from 30 fishing vessels — 15 Squid Jig and 15 Bouke Ami — ranging from 30 to 200 GT. Data included vessel characteristics, fuel consumption, number of fishing trips, trip duration, and catch production. FUI was calculated as the ratio of fuel consumption to total catch per trip. At the same time, the carbon footprint was estimated using the IPCC emission-factor approach based on diesel fuel consumption. Results showed that Squid Jig fleets had a lower average FUI (0.189 kg fuel/kg catch) compared to Bouke Ami fleets (0.252 kg fuel/kg catch). The average carbon footprint of Squid Jig fleets (0.611 kg CO₂-eq/kg catch) was also lower than that of Bouke Ami fleets (0.813 kg CO₂-eq/kg catch). Carbon footprint decreased by 34.7% with increasing vessel size in Squid Jig fleets, compared to only 11.7% in Bouke Ami fleets. These findings indicate that Squid Jig is a more fuel-efficient and environmentally sustainable fishing gear, providing a scientific basis for the development of low-carbon squid fisheries in Indonesia.

Abstract

The construction of the Landing Platform Dock (LPD) 163 M ship in the Warship Division of PT. XXX Indonesia is a project with a high level of complexity that requires effective project schedule control to minimize work delays. This study aims to analyze the construction scheduling of module I and module II using the Critical Path Method (CPM). The research method used is descriptive quantitative through the preparation of network planning and S-Curve analysis. The results of the study show that there are four scheduling alternatives, namely Schedule A (existing) for 59 days in block 122, Schedule B 54 days, Schedule C 57 days, and Schedule D 54 days. Scheduling B and D are the most optimal alternatives because painting, grand assembly, and quality control activities are on a non-critical path so they have slack and can accelerate the project duration. The results of the S-Curve analysis show that the plan progress in September 2025 increased from 65.8% to 99.4% in December 2026, the actual progress achievement (A) in March 2026 was only 31.1% while the plan was 84.6%, the assumed progress of the CPM results (B; D) reached 37.3% so there is a difference in progress achievement of 6.2%.

Abstract

Ballast tanks are among the most corrosive environments in oil tankers, with progressive thinning of transverse structures in the midship region posing a significant threat to hull girder integrity. Current maintenance practices are largely prescriptive, focusing on minimum-thickness compliance without explicitly relating measured conditions to the probability and consequences of failure. This often leads to reactive decisions and uniformly allocated inspection resources. This study aim was the structural integrity risk of transverse constructions in oil tanker ballast tanks by integrating the probability of failure with its consequences, and applies the resulting risk map to develop a risk-based inspection (RBI) and predictive maintenance (PdM) strategy. The methodology involves three stages: calibration of a probabilistic power-law corrosion model using Condition Assessment Program (CAP) thickness data from a double-hull product oil tanker; computation of ultimate bending capacity and probability of failure using the incremental-iterative method of the IACS Common Structural Rules, the First-Order Reliability Method, and Monte Carlo simulation; and quantification of each structural element's risk on a likelihood-severity matrix. Results show that risk is concentrated rather than uniformly distributed: deck and inner-shell longitudinals have the highest risk scores (9), followed by deck plating, longitudinal bulkhead, and stringer plates (score 8). The probability of failure at 35 years increases from approximately 10⁻⁵ to 2.9×10⁻³ when corrosion dispersion is considered. As risk is primarily governed by the dispersion of wastage rather than its mean, the proposed risk-based strategy is more efficient than conventional uniform periodic inspection.

Abstract

This study discusses the modification of the structure of the Offshore Supply Vessel (OSV) to be able to support the offshore drilling function by adding moonpool construction in the midship area. This modification aims to increase the operability of ships in Indonesian waters which have high oil and gas potential. The addition of a moonpool caused significant changes to the hull structure, so it was necessary to reanalyze the elongation strength of the ship. The analysis was carried out theoretically and numerically using the finite element method or FEM (Finite Element Method) to evaluate the response of the structure to various loading conditions such as full load, and operational, as well as wave sagging and hogging conditions. The results of the analysis include tension, deflection. which is then validated against the limits set by the Indonesian Classification Bureau (BKI). The results showed that despite the changes to the structure due to the addition of the moonpool, the ship's elongation strength was still within safe limits and met applicable regulations. This study contributes to the development of multifunctional OSV design and is expected to become a reference in the design of small scale drilling vessels in Indonesia.

Abstract

The Barito River navigation channel is characterized by dense traffic and dynamic river conditions that increase the risk of ship collision. Internal incident data from PT XXX recorded 135 ship accidents during 2023–2025, with collision ranking as the second largest category after grounding. This study analyzes the influence of organizational climate and Job Safety Analysis (JSA) implementation on crew safety behavior and their implications for collision prevention in the Barito River channel. A descriptive quantitative approach was applied using a closed-ended questionnaire distributed to 200 crew members operating tug and barge vessels and 5 port captains, with data analyzed through SEM-PLS. To complement the quantitative findings, a real-case assessment test involving five Port Captains was conducted using a realistic collision scenario. The results show that JSA implementation has a positive and significant effect on safety behavior and collision prevention, while safety behavior also has a positive and significant effect on collision prevention. Organizational climate shows a positive but statistically insignificant effect on safety behavior, while its direct effect on collision prevention is negative and significant. The model explains 64.7% of the variance in safety behavior and 62.1% of the variance in collision prevention, with both endogenous constructs also showing predictive relevance. The real-case assessment confirms that lookout quality, communication, role clarity, and pre-operational risk control are critical factors in preventing collisions in narrow river navigation. These findings highlight the importance of strengthening JSA practice and safe operational behavior to improve navigation safety in the Barito River channel
