Operational safety in cargo loading and unloading activities at Jetty Nusantara is greatly influenced by the effectiveness of scheduling land crane usage, which depends on two main factors: land crane maintenance and land crane operator skills. Several issues often encountered, such as reliance on designated cargo handling (PBM) parties, unexpected breakdowns of land cranes, and insufficient operator skills in crane operations, can affect operational safety. Poorly managed scheduling also worsens operational conditions, leading to fatigue, equipment damage, and an increased risk of workplace accidents. This study aims to analyze the impact of land crane maintenance and land crane operator skills on scheduling crane usage and its impact on operational safety in cargo loading and unloading at PT Samudera Maritime Indonesia. Using a quantitative approach and cross-sectional design, this study involved 70 respondents selected using the Slovin formula. The collected data were analyzed using SmartPLS software. The results of the study show that land crane maintenance and land crane operator skills have a positive and significant effect on scheduling crane usage and operational safety in cargo loading and unloading. The findings indicate that quality training and adequate training facilities can enhance employees' ability to manage risks and improve their performance. Effective scheduling also contributes to improved operational safety. The recommendations from this study are for PT Samudera Maritime Indonesia to continue improving land crane maintenance and the quality of training to support operational safety in the future.

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.
