Abstract

Ensuring consistent product quality in export-oriented seafood processing is essential to comply with international standards and maintain market competitiveness. This study evaluates the quality control performance of export-grade barramundi (Lates calcarifer) fillet production using an integrated approach combining Statistical Process Control (SPC) and Failure Mode and Effect Analysis (FMEA). The research was conducted over a seven-month period (August 2025-February 2026) at a seafood processing company in Denpasar, Bali, Indonesia. SPC tools, including check sheets, Pareto diagrams, p-control charts, and fishbone diagrams, were applied to monitor process stability and identify dominant defect types. The results indicated four primary defects: improper fillet cutting (42.65%), vacuum leakage (35.29%), labeling errors (10.29%), and residual scales (11.76%). The p-chart analysis showed that the process remained statistically under control, although defect proportions increased during peak production in December. Pareto analysis revealed that improper cutting and vacuum leakage contributed nearly 78% of total defects, highlighting critical control points in processing and packaging stages. FMEA further identified vacuum leakage as the highest-risk failure mode, with a Risk Priority Number (RPN) of 2160 due to its severe impact on product shelf life and export compliance. The integration of SPC and FMEA proved effective in distinguishing statistically stable processes from high-priority operational risks. The study demonstrates that combining quantitative monitoring with structured risk assessment enhances decision-making, supports targeted corrective actions, and strengthens quality assurance systems in seafood fillet processing industries.

Abstract

Maritime accidents remain a strategic issue due to operational complexity and human factors. Despite the implementation of the International Safety Management (ISM) Code, effectiveness is impeded by inconsistent procedures, inadequate supervision, and a suboptimal safety culture. The objective of this study is to formulate a national safety policy model for commercial vessels that incorporates multidimensional governance integration to minimize accident risks. A mixed-methods approach with a sequential explanatory design was applied to 186 certified seafarers, including masters, deck officers, chief engineers, and engineers on commercial ships anchored at the port of Tanjung Perak. Start using questionnaire survey of the linkert scale then data were further enriched through interviews, observation. The findings indicate that more than 90 percent of informants stated that there had been an increase in safety awareness on the ship. Nevertheless, elevated work pressures, fatigue risks, and inadequate inter-ministerial coordination were identified. The novelty this research in the development of a comprehensive policy model that integrates a variety of aspects, including regulatory, institutional, human resource, technological, and safety culture, into a unified framework. The efficacy of maritime safety systems hinges on their ability to proactively anticipate risks that transcend the boundaries of formal compliance.

Abstract

This study analyzes the performance reduction of a ship's main propulsion engine caused by cracks in the jacket cooling system. Efficient engine cooling is vital for maritime transport safety and operational efficiency, yet systems often face critical technical failures. Utilizing a qualitative descriptive case study design aboard the bulk carrier MV Sarah S, research data was gathered through observation, semi-structured interviews with engine officers, and logbook documentation. The results reveal an abnormal operating condition in cylinder No. 2, where coolant leakage through material hairline cracks led to a critical drop in jacket cooling pressure (from 3.5–4 bar down to 2–2.5 bar) and a significant surge in exhaust gas temperature to 590°C. Triangulation analysis identified poor cooling water quality (pH below the 8–10 standard) as the dominant root cause accelerating corrosion, material fatigue, and structural cracking. Consequently, heat dissipation failed, disrupting combustion and lowering engine efficiency. This study concludes that temporary corrective measures are insufficient. Sustained propulsion efficiency requires immediate structural repairs combined with rigorous water treatment management and strict adherence to the Planned Maintenance System (PMS).

Abstract

Maritime transportation is a major contributor to global trade but also generates significant atmospheric pollution from ship exhaust emissions. Tanjung Priok Port, Indonesia's largest seaport, experiences intensive vessel traffic that may adversely affect local air quality. This study estimates ship exhaust gas emissions in the Tanjung Priok Port area by integrating Automatic Identification System (AIS) data with the Trozzi emission estimation method. AIS data collected throughout 2024 were analyzed to determine vessel movements, ship types, gross tonnage, and operational modes (cruising, maneuvering, and hoteling). The busiest operational period was identified before estimating emissions of NOₓ, CO, CO₂, VOC, SOₓ, and PM. The results showed that November was the busiest month with 2,480 vessel movements, while 3 November 2024 recorded the highest daily traffic with 109 vessels. During the peak period, total emissions reached 641.81 kg/h of NOₓ, 2,750.63 kg/h of CO, 719.67 kg/h of CO₂, 648.58 kg/h of VOC, 458.44 kg/h of SOₓ, and 34.38 kg/h of PM. Container vessels were identified as the largest emission contributors, followed by tanker and cargo vessels. The study demonstrates that integrating AIS data with the Trozzi methodology provides a reliable activity-based emission inventory that can support sustainable port management, environmental monitoring, and maritime emission reduction policies in Indonesia.

Abstract

This article develops an auditable Automatic Identification System (AIS) framework for collision risk mapping within the Lombok Strait Traffic Separation Scheme. The framework combines track reconstruction, pairwise encounter detection, distance and time to closest approach point, speed-adjusted two-way vessel domain, exposure-adjusted temporal and vessel class comparison, and Kernel Density Estimation. Because the original raw AIS records are available for analysis, this ready-to-use prototype uses a clearly identified synthetic dataset and should not be submitted as an empirical article. The dataset contains 1,286,430 AIS messages, 5,982 valid track segments, and 2,135 encounter events. Crossing situations constitute 42.0% of the encounters; 18.0% are classified as high CPA urgency and 19.3% involve vessel domain violations. Hypothetical high-risk levels were higher at night than during the day (23.8% versus 13.0%; odds ratio 2.09), while the associated violation rates were 24.3% and 15.0%. Events involving ferries showed the highest exposure-adjusted violation rates, and the northern prevention zone had the greatest synthetic spatial risk intensity. This framework resolves previous denominator and intersection inconsistencies by separating encounter frequency, kinematic urgency, geometric intrusion, exposure, and spatial concentration. All outcome values ​​derived from the original AIS and VTS records are subject to scientific interpretation

Abstract

Oil and gas transmission pipelines operating beyond their original design life require comprehensive integrity assessments to ensure safe, reliable, and sustainable continued operation. Life-extension decisions should not rely only on asset age but must consider actual degradation conditions, operational risks, structural integrity, and remaining service capability. This study proposes an integrated pipeline integrity assessment framework to support technical decision-making for aging transmission pipelines. The proposed framework combines Failure Mechanism Identification (FMI), Risk Assessment (RA), Fitness-for-Service (FFS), and Residual Life Assessment (RLA) into a structured evaluation process. The methodology was applied to a 10-inch API 5L X52 condensate transmission pipeline located in Jambi, Indonesia. Inspection records, ultrasonic thickness measurements, operational data, and engineering evaluation reports were analyzed to determine the actual integrity condition of the pipeline. The results showed that external corrosion was the dominant degradation mechanism affecting the pipeline system. Risk assessment indicated that most evaluated pipeline segments remained within acceptable risk levels. Fitness-for-Service evaluation confirmed that the pipeline satisfied the required acceptance criteria, with sufficient wall thickness for continued operation. Residual Life Assessment demonstrated adequate remaining service capability beyond the original design life. This study confirms that integrated integrity assessment provides a systematic and technically justified approach for supporting risk-based pipeline life-extension decisions.
