ABSTRACT:- Reefer Plug is an important plug-in electrical technology that supports frozen truck operations on ships, especially to maintain the quality of sensitive goods such as frozen food and pharmaceuticals during sea travel. However, the implementation of reefer plug in Indonesia faces various challenges, including inadequate infrastructure, high investment costs, and regulations that still need to be refined. The main questions that arise are how Reefer Plug can meet the high power needs of frozen trucks, the technical, economic, and environmental impacts of its use compared to fossil fuel generators, and what strategies can be applied to optimize this technology. This study aims to analyze the technical benefits, economic impacts, and environmental sustainability of Reefer Plug, as well as provide strategic recommendations for improving its operational efficiency. The method used is a case study on the operation of Reefer Plug on the biggest ferry company in Indonesia Ferry ship with an analysis of regulations and modern logistics market needs. The results of the study show that Reefer Plug can increase energy efficiency by up to 40%, reduce carbon emissions by 30%, and reduce operational risks due to ODOL vehicles.
