Environmental engineering innovations for sustainable green port infrastructure

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.
