Indonesia's packaged juice sector has a large market and contributes to the country's GDP. It is necessary to have a
supply chain that responds to high customer demand to meet these needs. The warehouse acts as a storage and a source of information on the availability of goods to meet consumer demand, giving a significant impact on overall business process operations. There are still challenges in the warehouse that might lower warehouse operations' efficiency and make them less responsive to customer needs. This study aims to design improvements of the warehousing operations in the packaged juice industry through a Business Process Reengineering (BPR) approach by utilizing the Internet of Things (IoT) technology to improve time efficiency. This research presents 4 process improvement scenarios for packaged juice warehouses, with varied handling processing times for each scenario. Scenario 4 which uses automated inventory system using RFID, handheld mobile computers, and automated picking direction using voice which have the highest time efficiency, namely for raw material warehouses, inbound (8%), outbound (25%), and stocktake (35%) and finished goods warehouse, for inbound (3%), outbound (45%), and stocktake (25%).
