Abstract

The Indonesian maritime industry faces a critical human capital paradox, where a surplus of vocational graduates exists alongside persistent difficulty among shipyards in recruiting personnel capable of executing modern Product-Oriented Work Breakdown Structure and digital drafting workflows. This study investigates this disconnect through the pilot implementation of an Applied CAD for Maritime Engineering curriculum at a partner vocational high school, SMKN 5. Using a Guided Replication methodology, the intervention bridged the gap between theoretical software knowledge and industrial application by emphasizing parametric modeling and design-for-production logic. The results show that student aptitude is high, as evidenced by the rapid acquisition of three-dimensional modeling skills, while the national vocational infrastructure remains critically unprepared. The study identified a significant technological readiness gap in which existing school hardware was unable to support industry-standard software, requiring external technical intervention. These findings indicate that closing the maritime skills gap requires more than curriculum reform alone, but also necessitates fundamental improvements in school computing infrastructure and a pedagogical shift from software-centric instruction toward production-centric learning. This research proposes a scalable framework for integrating industrial competencies into vocational education to support the long-term development of Indonesia’s maritime workforce.

Abstract

The use of synthetic fibers in composite materials in the shipping industry provides mechanical advantages but produces non-biodegradable waste. This encourages the development of more environmentally friendly natural fiber-reinforced composite materials. This study examines the physical properties and tensile strength of composites made from a mixture of coconut petiole fibers and fiberglass, including the effect of immersion in seawater and freshwater for 30 days. The results show that the composites experience an average water absorption of 0.074% (freshwater) and 0.065% (seawater). Tensile tests show average tensile strength values ​​of 35.837 MPa (freshwater), 31.890 MPa (seawater), and 41.290 MPa (without immersion). Immersion in an aqueous medium reduces the tensile strength due to interfacial degradation between the fiber and the matrix. Coconut petiole fiber–fiberglass composites have the potential to be an alternative material for ship components with competitive and environmentally friendly mechanical characteristics
