Abstract

The research aims to analyze maritime safety and security policies in supporting the maritime transportation system. This research uses a descriptive method, because the data collected are in the form of words, images, and not numbers. The data comes from interview scripts, field observations/notes, Focus Group Discussions, videotapes, photographs, notes or memos, and other official documents. Data analysis uses an ethical and emic approach and a triangulation process. Informant determination uses a purposive technique. Research result: Maritime transportation in Indonesia has not yet developed optimally, but has strong potential to be developed, considering its characteristics of being able to carry out mass transportation. Therefore, the safety and security system is a key factor that must be considered and as a basis and benchmark for decision making. The safety and security system for maritime transportation in Indonesia has not been running optimally, accidents still often occur both due to natural factors and human factors. Government policies in the maritime sector, both the fishing industry and the shipping industry have not been implemented consistently in accordance with applicable laws. So far, the development of maritime potential has been hampered by structural problems, and there has been no national political awareness of the magnitude of the economic, fisheries and maritime potential.

Abstract

The purpose of this study is to examine how crew behavior affects shipping operational performance when maritime safety culture is used as a mediating variable. Using Flin's (2008) crew behavior instrument, Xi et al.'s (2025) safety culture instrument, and BIMCO Shipping's (2020) operational performance KPIs, data were collected through a questionnaire survey of 343 commercial ship crews in Indonesia, using a 1–5 Likert scale. External model testing (validity and reliability) and internal model testing (R2, f2, SRMR, and hypotheses) were conducted with SEM-PLS using SmartPLS 4. The results show that crew behavior has a significant impact on maritime safety culture (β = 0.936; p < 0.001). However, the direct impact on operational performance was small (β = 0.208; p < 0.018). These findings confirm that crew behavior only has an optimal impact when it is internalized into the organization's safety culture, so shipping companies need to strengthen safety policies, continuous training, safety-based leadership, and non-punitive reporting systems. Theoretically, this study expands the literature on safety management by showing that the ever-changing interaction between human elements and organizational culture determines how effective maritime organizations are.

Abstract

This study aims to analyze the factors that cause the difference in mooring service time between the Statement of Fact (SoF) issued by ITL Shipping Agency and the Pranota issued by PT Pelindo Balikpapan Branch. The research method employed was a qualitative method with a case study approach, with analysis conducted using fishbone diagrams to identify the gaps that emerged. The results of the study show that the main causes of time differences are seen from six aspects: Man, Machine, Method, Measurement, Material, and Mother Nature. This condition results in differences in the recording of mooring times, which have a direct effect on the calculation of mooring service costs and differences in bill values. This study emphasizes that improvement efforts need to be focused on improving the competence of Human Resources (HR), synchronizing the time recording system, strengthening the socialization of SOPs, optimizing document verification, and standardizing the time reference using UTC+08:00. These strategic steps are considered important to minimize time mismatches in the future and ensure the smooth and accurate process of mooring services at the Port of Balikpapan.

Abstract

“The Effectiveness of Smoke Detector Maintenance in Fire Mitigation Efforts on Board KM Tilongkabila,” supervised by Mr. Rizal Rochmansyah, S.Tr.Pel., M.Tr.T., and Mr. Riki Wanda Putra, M.Pd. This study aims to analyze the effectiveness of smoke detector maintenance in supporting fire mitigation efforts on board KM Tilongkabila. The research employed a descriptive qualitative approach, with data collected through field observations, semi-structured interviews with four key informants (the Captain, Second Engineer, Third Officer, and Radio Officer), and documentation review. Data analysis was conducted using the Miles and Huberman interactive model, which includes data reduction, data display, and conclusion drawing, strengthened by source and technique triangulation. The results indicate that smoke detector maintenance has been carried out routinely through monthly inspections, sensor cleaning, alarm testing, and documentation in the logbook. The alarm system is integrated with the bridge panel and the ship’s internal communication system, and is supported by regular fire drills. The main challenges identified include dust and humidity in the engine room, which may trigger false alarms. Overall, smoke detector maintenance is considered effective in supporting early fire mitigation; however, improvements are still needed in terms of sensor modernization and environmental control.

Abstract

This study examines how transactional leadership (TL) influences the retention intention (RI) of Indonesian seafarers through the mediating role of emotional exhaustion (EE) and the moderating effect of family support (FS). The research uses the Job Demands–Resources (JD–R) model to explain how excessive supervision, strict compliance, and punitive control can increase psychological strain and emotional fatigue. Data were collected from 298 crew members working on medium-sized vessels operated by national shipping companies and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results show that TL positively affects EE (β = 0.292, p < 0.001) and indirectly reduces RI (β = 0.037, p = 0.018), while maintaining a direct positive impact on RI (β = 0.317, p < 0.001). EE partially mediates the TL–RI relationship, suggesting that emotional fatigue can lead to “forced retention” driven by family and financial obligations. FS has a strong positive influence on RI (β = 0.576, p < 0.001) and moderates the EE–RI link (β = 0.102, p = 0.007), indicating its buffering role against emotional strain. Overall, the study highlights that balancing transactional leadership with supportive resources and structured recovery policies is crucial for sustaining crew retention in the maritime industry.

Abstract

This study examines how information literacy influences students’ disaster preparedness by incorporating risk perception as a mediating variable. Disaster-prone higher education environments require strong information comprehension skills to support readiness against potential hazards. The research involved 184 students from Merchant Marine Polytechnic of West Sumatra and STKIP Ahlussunnah, selected using purposive sampling. quantitative survey design approach was applied using SEM-PLS path analysis to evaluate direct and indirect effects. The results show that information literacy significantly influences disaster preparedness through an indirect effect mediated by risk perception (β = 0.205; p = 0.000). This finding highlights that risk perception strengthens the translation of information literacy into concrete preparedness actions. Practically, institutions should design information literacy programs that enhance not only access to technical data but als4o students’ awareness and appraisal of disaster risks. This study is limited by its focus on two campuses in a specific geographic area, suggesting the need for broader comparative studies. Overall, the research confirms that incorporating psychological components such as risk perception is essential for optimizing disaster preparedness strategies among university students.
