Refrigerated containers are used to export perishable goods, such as fruit, dairy, vegetables, fish, and meat through the main port of Tanjung Priok in Jakarta. The handling of refrigerated containers has a bigger challenge because it requires special handling so that the quality of the cargo is maintained. The current manual monitoring handling of refrigerated containers creates a high risk of damage and deterioration of cargo quality. The aim of this research is to design an improved process for handling refrigerated containers through the use of the internet of things (IoT) technology with a business process re-engineering (BPR) approach to reduce the risk of cargo damage with a real-time monitoring system. This research provides three scenarios for process improvement in handling reefer containers and resulted in different handling processing times for each scenario.
