This report is one of the outcomes of the student project execution being done by the writers as part of the graduation conditions for students. The project, which was being executed in one semester, is to make a design of an integration system for all business process being done in every department in Bimasena. Bimasena is an executive member club. The object includes all business process being done by the manager, Accounting Department, spa & Club Facilities Department, Program Ececution & Development Department, Members Relation Departement, and also the Inventory Department. The integration was needed as previously each department was going on its own with each respective system (if there is any). This resulted in complex business process, difficulties to retrieve information from one department to another, not to mention misommunications. The integration system, named Bimasena Enterprise Integrated Information System, is expected to be able to simplify every business process in the company, making it possible for every department to get real-time information from other department, and to avoid miscommunications. Bimasena itself is a club for the mines and energy society in Indonesia. It stood with an objective to be come the center of harmony and synergy of the mines and energy society in Indonesia, and also to be the focus for regional and international forums by facilitating business and social interaction. Bimasena also has an objective to improve the business relationship among the mines and energy society in the Asia-Pacific region through interactive dialogues and international forums.
