Abstract

This mixed-methods research examines green technology integration in maritime transportation engineering through stakeholder interviews with 37 participants and quantitative analysis of five case study sites across Indonesian maritime operations. The study evaluates LNG propulsion, hybrid systems, shore power, renewable energy, and vessel design efficiency across operational performance, educational preparedness, and implementation barriers. Results demonstrate substantial effectiveness (8.5/10.0 average) with fuel efficiency improvements of 12−20% and emission reductions of 18−35%. However, adoption remains constrained by capital cost premiums of 30−45%, payback periods of 7−14 years, and educational preparedness gaps showing only 42−58% workplace application rates. Implementation rates range from 8% (LNG) to 35% (vessel efficiency), reflecting financial barriers (38% of constraints) and infrastructure limitations. Findings establish that maritime sustainability requires coordinated technological, financial, and educational interventions, providing evidence-based frameworks for stakeholders in resource-constrained maritime economies.
