The spread of Covid-19 has led to the implementation of Large-Scale Social Restrictions (PSBB), social and physical distancing, to lockdowns to break the chain of spread of Covid-19, so this will definitely have an impact on the flow of loading and unloading of containers at Tanjung Emas Port, Semarang. This study aims to determine the flow of loading/unloading data and the influence of Covid-19 on the flow of loading/unloading containers at TPKS Semarang. This research is a type of correlation statistical analysis with a quantitative approach. The place and time of the research is at the Semarang Container Terminal in November 2022. The research instrument here is in the form of documentation. There are 3 data analysis techniques, namely descriptive statistical analysis, normality test, linearity test and Pearson product moment correlation test. The data analysis carried out showed that the results of the research from the descriptive statistical analysis test using the SPSS 26 application found that the average was 16,000 - 17,000 boxes/year. The normality test of all import and export data is normally distributed. The linearity test for all data gets linear results. Correlation statistical test with Pearson product moment showed that Covid-19 has no relationship with the flow of loading/unloading of imported and exported containers except for the flow of unloading/loading of imported containers in 2022.

This research was conducted to develop a state-of-the-art Android application to measure the satisfaction of agents involved in the sailing approval process. The main objective is to improve the efficiency and satisfaction of ship agents during the process of issuing sailing permits at the Harbour Master and Port Authority, Teluk Bayur, Sumatera Barat, Indonesia. This research involves the design and development of an Android-based survey application, which has undergone expert validation and usability testing to ensure its effectiveness. This research used the Plomp development model and involved 21 people who made arrangements at the Port Authority office as research subjects. The results of the study show that the newly developed application is valid for assessing agent satisfaction in managing the services for issuing Sailing Permits, with a material validity of 0.87 and a media validity of 0.88. Furthermore, the results of the agents' evaluation show that the Android-based agent satisfaction survey is very practical, with a practicality rate of 93%. This study also outlines the limitations encountered during the research and proposes future recommendations to improve the research. In conclusion, this research highlights the practicality and validity of the developed Android-based Agent Satisfaction Survey application.

The International Convention for the Prevention of Pollution from Ships (MARPOL) is a global legal instrument that plays a central role in protecting the marine environment from the impacts of shipping operations. This article aims to analyze the effectiveness of MARPOL implementation both globally and in Indonesia, taking into account institutional, technological, and maritime economic dimensions. The study employs a qualitative descriptive approach supported by secondary data derived from official International Maritime Organization (IMO) documents, Tokyo Memorandum of Understanding (Tokyo MoU) annual reports, scholarly publications, and Indonesian government reports covering the period 2015–2025. The findings indicate that, at the global level, MARPOL has been effective in curbing marine pollution through strengthened monitoring systems, adoption of environmentally friendly shipping technologies, and incentive mechanisms for the maritime industry. Advanced economies such as Japan, the Republic of Korea, and several European states have achieved high levels of compliance owing to cross-sectoral policies and robust financial support. In contrast, MARPOL implementation in Indonesia remains constrained by weak law enforcement, inadequate port reception facilities, and the high costs associated with adopting low-emission technologies. Major obstacles include limited port infrastructure, insufficient crew training on ship waste management, and low environmental awareness within the shipping sector. To optimize MARPOL implementation, the study recommends strategies to strengthen institutional capacity, provide incentives for green technologies, and enhance international cooperation. With these measures, the effectiveness of MARPOL in reducing marine pollution in Indonesia is expected to improve substantially and sustainably.

This study aims to examine the implementation of a cadet mentoring model based on a Humanist, Sustainable, Smart, and Eco-Friendly Campus at Politeknik Pelayaran Sumatera Barat (West Sumatra Maritime Polytechnic). Within the context of vocational maritime education, mentoring plays a crucial role in shaping cadets’ character, discipline, and social responsibility. A humanistic approach emphasizes respect for humanitarian values, while the principles of sustainability, smart campus design, and eco-friendliness provide a framework for developing a campus that supports holistic learning processes. The research employs a descriptive qualitative methodology using observation, in-depth interviews, and document analysis involving members of the academic community and cadets. Findings indicate that implementing a mentoring model grounded in these concepts enhances cadets’ environmental awareness, social ethics, and adaptive capacities in responding to global maritime challenges. Moreover, integrated development programs that incorporate digital technologies and environmentally friendly practices further reinforce a sustainable educational ecosystem. Recommendations include strengthening training for cadet mentors, integrating character- and environment-based content into the curriculum, and optimizing green campus infrastructure to support the realization of a smart, eco-friendly campus.

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
