Refueling or bunkering is an activity carried out when the ship is ready to sail. In refueling activities, it is very dangerous for work accidents to occur, the implementation of refueling (bunkers) which is less than optimal can also cause accidents and losses for the company and other parties. These losses include oil spilling into the sea, fires and so on. The execution of refueling is still less than optimal in using personal protective equipment and there is a lack of coordination between several crew members. The aim of this research is to determine the causes of work accidents, efforts are being made to improve supervision of refueling on ships. Supervision during the fuel oil filling process is very important because this activity carries a very high risk of work accidents. This method was written using field methods (field research), namely observation and interviews (interviews) and literature (Library Research). Factors that cause work accidents during the process of filling ships with fuel oil on ships are lack of coordination between the officers involved, lack of awareness in the use of personal protective equipment in accordance with SOP (Standard Operational Procedure)..

The proliferation of network information algorithms (NIAs) in contemporary society has sparked significant ethical concerns regarding their societal impact. This study investigates the influence of NIAs on social interactions, decision-making processes, and the perpetuation of structural biases through a multidisciplinary perspective (Ananny, 2023). The findings reveal that while NIAs enhance operational efficiency across various domains, they also introduce ethical challenges, including privacy infringements, systemic inequities, and algorithmic opacity, which threaten social justice. Employing Ananny’s (2023) conceptual framework—which categorizes NIAs into three dimensions: encounters, observation, and probability/temporality—this research deconstructs the operational mechanisms of these algorithms. The analysis demonstrates that NIAs not only replicate historical biases but also engender new forms of discrimination through ostensibly neutral predictive processes. For example, algorithm-driven recruitment systems may perpetuate gender disparities if their training data reflects prior discriminatory practices (Crawford, 2021). This study underscores the inextricable link between technological ethics and societal context, arguing that an overreliance on algorithmic systems risks undermining human autonomy (Zuboff, 2019). The originality of this research lies in its integration of computational ethics theory with empirical case studies, such as the deployment of NIAs in mass surveillance, where privacy is often compromised in pursuit of perceived security. To ensure academic rigor, the arguments are developed through a critical comparison with prior research (e.g., Mittelstadt et al., 2016), while avoiding redundancy in phrasing or structure. Scholars such as Floridi (2019) emphasize the necessity of algorithmic transparency in regulatory frameworks. However, critics like Noble (2018) argue that technical solutions alone are inadequate; structural reforms in data governance and corporate accountability are essential to mitigate the misuse of NIAs. In response, this study proposes an ethical framework that not only addresses technical risk mitigation but also incorporates civic participation in algorithmic decision-making processes. The ethical implications of NIAs necessitate a holistic approach that integrates principles of data justice, independent algorithmic auditing, and public digital literacy. Future research should explore inclusive models of algorithmic governance, particularly in developing nations where regulatory frameworks often lag behind technological advancements. This study concludes with a reflective inquiry: How can algorithmic accountability be ensured if developers lack transparency regarding data sources and programming logic? By addressing these questions, this research contributes to the ongoing discourse on the ethical governance of NIAs and their societal implications.

The maritime industry operates in a complex, rapidly evolving global environment where decision-making accuracy is critical for operational efficiency, sustainability, and risk mitigation. Traditionally, maritime leadership has relied heavily on experience-based decision-making, often leading to cognitive biases and strategic inefficiencies. This study examines the role of scientific paradigms in managerial decision-making, emphasizing how structured epistemological reasoning enhances strategic accuracy and reduces decision-making errors. This research provides original value by addressing the limited integration of structured decision-making models in maritime leadership, which has been largely overlooked in previous studies. While scientific reasoning has transformed decision-making in industries such as finance and healthcare, its application in maritime management remains underdeveloped. The study explores the following research questions: To what extent do scientific paradigms influence managerial decision-making in maritime leadership? How can structured reasoning reduce bias and improve decision accuracy? Using a qualitative approach, semi-structured interviews were conducted with maritime experts, lecturers, and postgraduate students, followed by thematic analysis and comparative evaluation. Results indicate that structured decision frameworks significantly improve managerial effectiveness, yet barriers such as industry conservatism and limited competency development hinder widespread adoption. The study concludes that integrating scientific reasoning into maritime leadership training programs can enhance decision accuracy, promote evidence-based management, and ensure sustainable strategic planning.
