Abstract

This research examines the integration of environmental engineering innovations and maritime vocational education in developing sustainable green port infrastructure in Indonesian ports. Employing qualitative methodology with semi-structured interviews of 15 maritime stakeholders and case study analyses of three ports, the study evaluates five sustainability dimensions: energy efficiency, waste management, sustainable logistics, technological monitoring, and workforce competency. Results demonstrate substantial effectiveness with an aggregate score of 9.0/10.0, including 35% energy reduction through renewable integration, 40% waste recycling enhancement, and 25% logistics emission decrease. Workforce competency development achieved exceptional 9.1/10.0 performance, with 95% graduate preparedness for green technology implementation, establishing direct links between curriculum alignment and operational sustainability. Implementation barriers include financial constraints (15-30% cost premium), technological complexity, and coordination challenges. This research uniquely demonstrates that sustainable port transformation requires simultaneous investment in advanced systems and human capital, providing evidence-based strategies for port authorities, policymakers, and educational institutions pursuing integrated sustainability frameworks in resource-constrained maritime economies.
