Determination of Solar-Powered Shipyard Location Using Integrated-MCDM Method

Maritime shipping contributes nearly 3% of global greenhouse gas emissions.To achieve zero-carbon shipping, Indonesia, with its abundant sunlight, can use solar cell technology for electric-powered ships, necessitating carefully selecting shipyard locations.To address this challenge, this research integrates DEMATEL with six MCDM ranking methods (CoCoSo, MOORA, TOPSIS, ARAS, OCRA, and WASPAS).Using 23 comprehensive criteria, the study identifies the most suitable locations for solar-powered shipyards.The analysis showed PT Dok Pantai Lamongan and PT Armada Bangun Samudra as the top locations, consistently ranked by all methods.A significant contribution of this research lies in its application of objective decision-making methods and new parameters related to the shipyard selection process.Sensitivity analysis confirmed the robustness of the results, with DEMATEL-MOORA identified as the most straightforward approach.This study advances Indonesia's pursuit of a sustainable maritime industry by offering reliable, objective decision-making methods for site selection.
