The Critical Blood Bank’s Inventory Management Improvement Using Information System Through the Implementation of Internet of Things

Abstract

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.
