Abstract

Port of Tanjung Priok, Indonesia, faces excessive ship and container dwell times—particularly at Terminal III—driven by container traffic growth that outstrips the capacity of handling facilities. This study analyzes container ship handling time (dwell time), assesses the impact of adding ship-to-shore cranes, and estimates the required berth length and yard area based on projected container flows. Secondary data on container throughput for 2009–2013 were used and projected forward to 2014–2018. Queueing analysis was performed with an M/M/c model to obtain standard system performance metrics (L, Lq, W, Wq), which were then converted into dwell-time estimates; berth and yard requirements were calculated using berth-throughput approaches and standard space requirements per TEU. Results indicate that under the existing equipment level of 39 cranes, dwell time rose from about 6.92 days in 2009 to more than 14 days in 2012–2013, substantially exceeding operational standards. Simulations show that increasing the number of cranes to 51–55 units would reduce dwell time to approximately 5.85–6.82 days. Projected infrastructure needs for 2018 include an aggregate berth length of roughly 7,339 m and a stacking yard area of about 168.9 hectares. The findings underscore the urgent need for additional handling equipment and infrastructure development and point to opportunities for enhancing analysis and operational monitoring through the application of artificial intelligence for dwell-time prediction and real-time smart-port management.

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

In an increasingly competitive service industry, understanding the determinants of user satisfaction is essential for organizational growth and customer retention. This study aims to examine the effects of service quality and service loyalty on user satisfaction at PT. Adhigana Pratama Mulya Batam. Employing a quantitative ex-post facto design, data were collected through questionnaires distributed to 200 respondents, consisting of ship crew members as direct users of the company’s services. The data were analyzed using multiple linear regression with the SPSS application. The results reveal that both service quality (t(197) = 4.419 > 1.984, p < 0.001) and service loyalty (t(197) = 9.957 > 1.984, p < 0.001) have significant positive effects on user satisfaction, while their combined influence is also statistically significant (F(2, 197) = 96.379 > 3.00, p < 0.001). These findings indicate that higher levels of service quality and employee loyalty lead to greater user satisfaction. The study suggests that the company should strengthen employee training, enhance user engagement, and continuously improve global service standards. Future research should incorporate additional factors such as infrastructure, technological facilities, pricing competitiveness, and brand image to obtain a more comprehensive understanding of user satisfaction

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.
