Abstract

Non-compliance in the execution of lifeboat maintenance procedures significantly heightens operational risks and impairs evacuation effectiveness during maritime emergencies. This study evaluates the conformity of lifeboat maintenance and operational readiness on board the bulk carrier MV. Aliyah Pratama against the specific requirements of the Safety of Life at Sea (SOLAS) Chapter III Regulation 20 and the Life-Saving Appliances (LSA) Code. Utilizing a qualitative descriptive case study approach, data were collected over a 12-month period at Cilegon Anchorage through direct field observations, structured interviews with three key deck officers, and systematic reviews of the ship’s Planned Maintenance System (PMS) documentation. A compliance matrix was developed to benchmark observed mechanical and operational conditions against regulatory standards. The findings reveal critical discrepancies, including mechanical stiffness in the starboard gear brake, active corrosion on wire falls and winches, hardened watertight door seals, and expired emergency rations. Furthermore, abandon-ship drills demonstrated a lack of situational awareness and muster list comprehension among the crew. Root cause analysis, structured via the Ishikawa (Fishbone) framework, indicates that these non-conformities stem from superficial, visually limited inspections, high operational workloads, an aggressive saline environment, and shore-based procurement delays. The study concludes that the vessel's current maintenance execution functions primarily as an administrative formality rather than a rigorous functional safeguard. Corrective recommendations prioritize the implementation of deep-technical functional testing, expedited supply-chain logistics for safety equipment, and mandatory pre-drill tactical briefings to restore optimal evacuation.

Abstract

Operational activities on board a ship constitute a work environment with a high risk of workplace accidents. One of the challenges that is still frequently encountered relates to the crew’s suboptimal compliance with safety procedures and the use of personal protective equipment (PPE), resulting in a significant potential for accidents. This study focuses on evaluating the implementation of workplace safety equipment on ships as well as examining crew behavior in support of workplace accident prevention efforts. A qualitative approach was applied in this research, utilizing observation, interviews, and documentation as data collection methods during a 12-month period of sea training aboard the KM. Kelud. Research findings indicate that the occupational safety system has been supported by the availability of safety equipment, standard operating procedures, and the regular conduct of safety meetings. However, its implementation in the field has not been consistent, as it remains influenced by individual awareness levels, established work habits, factors related to workplace comfort, and supervision that has not yet been optimized. Consequently, the use of workplace safety equipment has not been fully effective in reducing workplace accident rates, where human factors remain the most dominant cause. This situation highlights the need to strengthen safety culture through continuous training, improve the effectiveness of supervision, and enforce strict penalties to foster discipline among the ship’s crew.

Abstract

The hatch cover is a critical structural component of a general cargo vessel, designed to safeguard cargo from seawater ingress and maintain watertight integrity. This study evaluates the constraints affecting the execution of planned hatch cover maintenance aboard MV. Orient King. A qualitative single-case study design was employed over a 12-month onboard observation period. Data was collected through semi-structured interviews with three key deck personnel (Chief Officer, Bosun, and Able Seaman), structured operational observations, and a review of maintenance logs. Thematic analysis of the data revealed that maintenance compliance is fundamentally hindered by aggressive marine corrosion, a brittle supply chain causing 2-to-3-month lead times for critical spare parts (e.g., rubber packing, hydraulic hoses), and a dense operational tempo that routinely forces the deferral of scheduled Planned Maintenance System (PMS) tasks. Consequently, temporary repairs are frequently substituted for permanent solutions, elevating the risk of cargo damage. To mitigate these risks, this paper proposes a prioritized action plan, emphasizing strict adherence to the company's Safety Management System (Document No. JSP E41), optimized spare-part inventory control, and enhanced supervisory protocols.

Abstract

Occupational Safety and Health (OSH) management in Liquified Natural Gas (LNG) terminals requires stringent alignment with both general workplace safety and process safety protocols. This study evaluates the implementation of the OSH Management System (SMK3) at PT X, an LNG logistics terminal in Indonesia, focusing on employee Personal Protective Equipment (PPE) compliance and visitor safety controls. Utilizing a qualitative case study design, data were collected through field observations, document reviews, and semi-structured interviews with nine key informants across operational and safety divisions. The data were analyzed using a formal SWOT/TOWS matrix to develop strategic interventions. The findings indicate that while PT X’s institutional procedures—such as mandatory safety inductions, daily toolbox meetings, and medical fit-to-work screenings—are consistent with ISO 45001 standards, critical field execution gaps remain. Empirical evidence highlights recurring PPE non-compliance driven by human factors (e.g., thermal discomfort), visitor violations of electronic device restrictions in hazardous explosive zones, and logistical bottlenecks due to insufficient visitor PPE inventory during peak periods. The study concludes that achieving optimal safety compliance requires moving beyond bureaucratic procedures. Practical implications include the necessity for risk-based PPE procurement, the enforcement of a controlled intrinsically-safe device management policy, and enhanced human-centric safety supervision.

Abstract

Screw-press operation is a major determinant of oil recovery at the pressing station of a palm oil mill, but field comparisons may be distorted when pressure levels are observed on different machines. This study re-examined the relationship between operating pressure and residual oil in press fibre at PTPN IV Kebun Mayang using an observational dataset comprising 15 once-daily measurements from three screw presses over five recorded sampling dates in 2025. Operating pressure was recorded at the time of sampling, and press-fibre oil, moisture, and non-oil solids were measured on a wet basis using a FOSS NIRS DA1650 instrument with the installed mill calibration. Mean pressure and oil loss were 40.4 ± 1.82 bar and 3.756 ± 0.804% for Machine 1, 45.0 ± 4.00 bar and 3.404 ± 0.476% for Machine 2, and 50.0 ± 1.58 bar and 3.176 ± 0.423% for Machine 3. An unadjusted linear regression indicated a decrease of 0.088 percentage points in oil loss per 1-bar increase in observed pressure (95% CI: −0.142 to −0.034; p = 0.004). After adjustment for machine and sampling date, the estimated pressure coefficient was smaller and statistically uncertain (−0.039 percentage points per bar; 95% CI: −0.164 to 0.086; p = 0.485). The data therefore suggest an inverse descriptive relationship between pressure and oil loss, but they do not establish a causal pressure effect or identify an optimum pressure because pressure was confounded with machine identity and kernel damage, oil impurities, energy consumption, throughput, and equipment wear were not quantified.

Abstract

This study aims to analyze the influence of the physical condition of mooring lines and supporting mooring components on the smooth berthing process of MT. GIAT ARMADA BERSAMA 04. The berthing process is a critical operational phase requiring a highly reliable mooring system to ensure the safety of the vessel, cargo, crew, and port facilities. Employing a qualitative descriptive method, data were collected through field observations across 12 berthing operations, structured interviews with deck officers, and document analysis. The findings revealed that the physical deterioration of the spring lines—specifically characterized by a visible diameter reduction, bird-caging, and surface abrasion exceeding the 10% broken strand threshold—contributed to severe operational difficulties. Furthermore, corroded deck fittings increased mechanical friction, leading to ropes jamming in the mooring chocks and significant delays in tension adjustment. Evaluated against the retirement criteria and inspection parameters defined by the OCIMF Mooring Equipment Guidelines (MEG4) and IMO safety mandates, the vessel’s mooring components operated below acceptable minimum breaking load (MBL) safety margins. Immediate replacement of degraded lines and the implementation of a strict Line Management Plan (LMP) are imperative to restore operational precision, mitigate occupational hazards, and enhance overall port efficiency.
