Abstract

The rising manning cost over the past three years has become a prominent issue at PT Pertamina International Shipping, where this expense accounts for the largest share of the company’s operational expenditure. This study examines the key factors driving the increase in manning cost and explores how cost efficiency strategies can be applied within the crewing function. Employing a qualitative approach, data were collected through observations, semi-structured interviews with three key personnel, and analysis of financial reports and crew service records over an 11-month period in 2022–2023. The findings reveal three primary inefficiencies scheduling discrepancies causing 2–7 days of delays, suboptimal invoice verification leading to monthly overpayments of approximately 50–100 million rupiah, and overstaffing beyond minimum crew requirements, inflating costs by 10–15%. These inefficiencies result in avoidable expenses of 1–1.5 billion rupiah monthly. The study recommends adopting digital scheduling tools, automated verification systems, and optimized crew allocation to reduce costs while maintaining operational safety. These strategies can save billions annually, improve crew welfare, and contribute to maritime management literature by addressing cost efficiency in state-owned enterprises, offering a blueprint for Indonesia’s shipping industry.

Abstract

This study examines an empowerment program designed to develop a digital entrepreneurial mindset among Generation Z maritime students by strengthening self-efficacy and cognitive flexibility. Responding to the accelerating digitalization of the maritime sector, the program aimed to shift student perspectives from traditional seafaring roles toward innovation-driven, technology-based entrepreneurship. Adopting a Participatory Action Research (PAR) model, the intervention involved 118 second-semester students at Politeknik Pelayaran Sumatera Barat and comprised stages of preliminary assessment, socialization and motivational seminars, two-day training workshops using Creative Problem Solving and Design Thinking, digital business idea simulations, mentoring, and reflective evaluation. Data collection included pre–post surveys, direct observation, written student reflections, facilitator notes, and triangulation across sources; qualitative descriptive analysis identified thematic changes in self-efficacy, cognitive flexibility, and entrepreneurial orientation. Post-intervention findings show notable increases in students’ confidence to express ideas, make decisions, and assume leadership roles, alongside enhanced cognitive flexibility manifested in multi-perspective problem solving and creative solution generation. Participants produced viable digital maritime business concepts (e.g., vessel-tracking applications, online seafarer training platforms, and logistics services), and demonstrated improved communication, teamwork, and pitching skills. The study recommends curriculum integration, establishment of a campus digital maritime incubator, stakeholder engagement for industry linkage, and longitudinal evaluation to sustain and scale outcomes. Overall, the intervention advances a replicable model for preparing adaptive, innovative maritime graduates capable of contributing to Indonesia’s digital maritime economy.
