This qualitative study develops and evaluates a mentorship-based educational model designed to facilitate the transfer of occupational health and safety knowledge from veteran seafarers to maritime cadets in Indonesian maritime vocational institutions. While maritime graduates receive comprehensive technical training aligned with Standards of Training, Certification and Watchkeeping for Seafarers (STCW) standards, they often report feeling unprepared for the health and safety challenges they face at sea, indicating significant gaps in experiential knowledge transfer. The study conducted interviews with 20 veteran seafarers, 12 maritime lecturers, and 15 cadets, alongside a pilot implementation across three BPSDMP institutions. The findings identify key tacit knowledge areas that are insufficiently addressed in current curricula, particularly in practical emergency response adaptation (100% stakeholder recognition), fatigue self-management (94.7%), and psychological coping strategies (91.5%). The research reveals strong support for structured mentorship programs, emphasizing one-on-one relationships (100% cadet endorsement), post-graduation continuation (100% lecturer/cadet support), and weekly digital communication (100%). However, the successful implementation of these programs requires significant professional development for lecturers to facilitate mentorship roles (2.0-point capacity gap), formal institutional policies to legitimize mentorship, and preparation for veterans in pedagogical techniques. Pilot results demonstrate the feasibility of this model across diverse contexts, with high cadet knowledge gains (4.4/5.0 average) and veteran satisfaction (4.6/5.0), though variations across institutions highlight enabling conditions that influence outcomes. This study provides evidence-based implementation guidelines for BPSDMP institutions, offering a roadmap for integrating veteran experiential wisdom into maritime education, with implications for improving both the technical competence and resilience of future maritime professionals.

The accelerating pace of technological transformation in the global maritime industry demands corresponding institutional readiness within maritime vocational education systems. Yet, the organizational structures, leadership capacities, and faculty competencies required to sustain such transformation remain insufficiently understood. This study investigates how organizational change management, institutional leadership practices, and faculty capacity development collectively support sustainable technology integration in maritime vocational education in Indonesia. Employing a qualitative research design, data were collected through semi-structured interviews with 12 maritime education experts, 18 vocational lecturers, and 15 recent graduates from three maritime polytechnic institutions. Data analysis followed a three-stage procedure encompassing thematic analysis, cross-group comparison, and narrative synthesis. The findings reveal five interconnected themes: strategic leadership alignment, organizational culture readiness, structured faculty professional development, industry–institution collaborative governance, and sustainability-oriented curriculum embedding. Cross-group comparisons indicated that while experts emphasized systemic reform, lecturers prioritized pedagogical support, and graduates highlighted experiential coherence. The study contributes a contextually grounded framework demonstrating that sustainable technology integration requires simultaneous and coordinated advancement across leadership, organizational culture, and human capacity dimensions rather than isolated interventions.

Global decarbonization pressures and technological disruption in maritime industries create urgent demand for deck and engine officers possessing both traditional operational competencies and contemporary green technology expertise. This research examined how blended learning designs combining simulator based instruction, theoretical instruction, and hands on practical training effectively integrate green shipping competencies such as alternative fuel propulsion, environmental compliance, and IMO 2050 carbon reduction into vocational maritime officer education. A mixed methods quasi experimental design compared learning outcomes between blended learning groups consisting of simulator, theory, and practical instruction and traditional instruction control groups across four maritime institutions (n = 184 students). Results demonstrated significant advantages for blended learning on green technology competency assessment and knowledge transfer measures. Instructor technological pedagogical content knowledge significantly predicted student outcomes, highlighting the importance of teacher capacity development. Thematic analysis of faculty interviews with step by step open and focused coding revealed that institutional barriers such as simulator equipment costs, faculty technological pedagogical knowledge limitations, and curriculum time constraints substantially limited green technology integration despite widespread recognition of its importance. Representative participant quotations illustrate the experiential texture of these barriers and enablers. The study contributes an empirically validated blended learning framework for maritime green technology education that positions simulator based experiential learning within an experiential learning cycle framework, advances technological pedagogical integration in maritime vocational contexts, and provides evidence based guidance for institutions navigating the pedagogical and resource tensions of decarbonization era officer education.

The maritime management sector increasingly demands graduates equipped with marketing acumen and innovation capacity alongside traditional operational competencies, yet maritime vocational curricula have been slow to integrate these dimensions systematically. This study investigates how systematic curriculum design can facilitate the integration of marketing and innovation competencies into maritime management programs within Indonesian maritime vocational education. Employing a qualitative research design, data were gathered through semi-structured interviews with 12 curriculum and maritime industry experts, 18 maritime management lecturers, and 15 recent graduates across three maritime polytechnic institutions. Analytical procedures combined thematic analysis, cross-group comparison, and narrative synthesis. The findings reveal five curricular dimensions requiring systematic integration: industry-responsive competency mapping, innovation-oriented pedagogical design, marketing knowledge embedding within operational modules, experiential industry-linked learning architecture, and outcome-based assessment alignment. Cross-group analysis demonstrated that experts emphasized strategic market positioning of maritime services, lecturers identified structural rigidity as a primary barrier to innovation integration, and graduates reported a disconnect between curricular content and the commercial realities of contemporary maritime management. The study contributes a systematic curriculum design framework grounded in the triple helix model and ADDIE methodology, positioning marketing and innovation not as supplementary electives but as structurally integrated dimensions of maritime management professional competence. Each framework component is explicitly derived from a corresponding empirical theme through a step-by-step mapping process, ensuring methodological transparency and design credibility.

This qualitative study investigates the integration of E-learning and Digital Assessment at STIP Jakarta and its impact on the work readiness of Diploma-IV cadets, aligned with international STCW competency standards. Through in-depth interviews and focus group discussions with 70 final-year cadets, the research reveals a dualistic outcome: while digital tools are highly effective in delivering theoretical knowledge and developing simulator-based operational skills, they exhibit significant limitations in fostering hands-on practical abilities and essential psychosocial competencies such as leadership and mental resilience. The findings identify a critical "digital-practical divide," where cadets report high digital confidence alongside underlying anxiety about real-world application. The study concludes that a balanced, hybrid pedagogical model is essential, leveraging technology not as a replacement but as a complement to traditional practical training. This approach is vital for Indonesia’s maritime sector to develop truly work-ready graduates who are both technologically proficient and psychologically prepared.

The modern transportation sector must consider its environmental impact particularly air pollution in addition to improving efficiency and speed. One of the main factors contributing to air pollution and global warming is the exhaust emissions produced by fossil fuel-based modes of transportation. Wing in Ground (WIG) craft are vehicles that use ground effect to fly low over water or land with lower energy consumption than conventional aircraft. This is one alternative mode of transportation that is beginning to attract attention. The literature explicitly addressing the relationship between WIG Craft design and air pollution impacts remains relatively limited; therefore, studies need to be developed that explore preventive measures to minimize air and noise pollution from this technology. Research focusing on the potential pollution and environmental impacts generated by WIG Craft is still very limited; this is because WIG Craft is a technology not yet produced for public transportation, and another factor is that research focus remains on design, stability, and control. Given these conditions, this study is important for identifying and formulating preventive strategies to reduce air and noise pollution from the use of WIG Craft. Purpose – This systematic literature review aims to comprehensively synthesize the current evidence on pollution prevention strategies in WIG craft design. Methodology – The initial phase of the study involved a systematic literature review. This Systematic Literature Review investigation was guided by the PRISMA analysis. Because of its substantial data collecting and comparatively strict and precise process. Findings – The potential emissions from WIG craft can be reduced through the design of green propulsion systems using electric power and low-carbon fuels. To mitigate the environmental footprint of Wing-in-Ground craft, researchers have proposed a combination of advanced aerodynamic design, noise suppression technologies, and optimized operational strategies.
