Abstract

This study addresses persistent waste-management challenges in coastal urban areas by optimizing the performance of waste-processing equipment at the Reduce-Reuse-Recycle (TPS3R) facility in Pariaman City. It was conducted through a Reliability-Centered Maintenance (RCM)–based repair and preventive maintenance program. The intervention combined field observation, identification of critical components, operator technical training, and the implementation of a structured maintenance schedule adapted to local operational conditions. Implementation involved collaboration among TPS3R management, local community members, and technical staff from Politeknik Pelayaran Sumatera Barat. Data were collected through direct observation, semi-structured interviews, and documentation of maintenance activities. Post-intervention evaluation demonstrated substantive gains in machine processing efficiency, up to an 80% improvement relative to baseline and a marked reduction in breakdown frequency. Operators showed measurable increases in technical competence and consistent adherence to Standard Operating Procedures (SOPs) for safe and effective machine operation. The findings underscore the value of vocational higher-education–community partnerships for technology adaptation, capacity building, and fostering a maintenance culture that supports sustainable urban waste systems. The program represents a scalable, replicable model for similar coastal contexts and contributes to Sustainable Development Goals 11 (Sustainable Cities and Communities) and 12 (Responsible Consumption and Production).

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.

Abstract

Penelitian ini bertujuan untuk menginvestigasi dan mengetahui pengaruh kelas gabungan antar tingkatan (combined grade) melalui metode role playing terhadap hasil praktek fungsi navigasi bagi taruna/i program studi Nautika angkatan II dan IV di Politeknik Pelayaran Sumatera Barat. Penelitian ini menggunakan metode quasy exsperiment. Data diperoleh melalui Comprehensive Assessment (Function 1. Navigation at The Operational Level) sesuai dengan STCW 78 as Amandement (Regulation A-II/2). Sebanyak 36 taruna/i Program studi Nautika angkatan II dan IVyang di ambil secara acak sebagai sampel penelitian. Hasil analisis data dengan uji-t (t-test) pada post test menunjukkan ada perbedaan yang signifikan antara nilai hasil belajar praktek fungsi navigasi kelompok gabungan antar tingkatan/angkatan (combine grades) dengan kelompok per angkatan melalui metode role playing. Ditunjukkan dengan nilai rata – rata peningkatan tes awal dan tes akhir kelas gabungan yaitu 5,67. Sedangkan, nilai rata – rata peningkatan kelas kontrol angkatan II sebesar 1,25 dannilai rata – rata angkatan IV sebesar 1,00. Dengan demikian,strategi kelompok gabungan antar angkatan (combine grade)menggunakanmetode Role Playing lebih efektif dan efisien dalam peningkatan perolehan hasil belajar praktek dibandingkan pembelajaran praktek menggunakan kelompok homogen (single grade) atau kelompok per angkatan.
