The critical blood bank’s inventory management improvement using information system through the implementation of internet of things

Blood Stockout cases are a common occurrence in Indonesian Hospitals. It is crucial especially in an emergency situation, where the delay process of blood replenishment and distribution could cause death to the patient. The problem of blood replenishment and distribution is caused by the time inefficiency or manual data communication among Hospitals and Indonesian Red Cross. The purpose of this research is to design process improvement of hospital blood bank’s inventory management through an information system and the utilization of Internet of Things. Business Process Reengineering approach was used to show the process improvement of management inventory in Hospital Blood Bank (HBB). The method in this study is information system development with entity relationship diagram (ERD), relational database, use case diagram, and data flow diagram (DFD). The results have five scenarios of process improvement. The best scenario could increase the efficiency of process time by 75.63%, which previously took 7.14 hours to 1.74 hours.
