Accountability of Course Graduation Records using Permissioned Blockchain in Hyperledger Fabric

Blockchain technology could be implemented not only in digital currency, but also in other fields. For example implementation is in education sector, namely graduation information system. Information system aims to facilitate the process of sending information carried out by parties involved in the system. But this often has problems, including caused by the condition of the system that is often down, process that is still manual (not integrated), human mistakes until data security. In this research we propose the system run on the decentralized and stored in distributed ledger and facilitate the audit process by monitoring data transparently, secure, immutable and accountability. This purpose of this research is to implement permissioned blockchain for storing the graduation records (log and course records) and develop a web application based chaincode to ensure the security authorized participants using Hyperledger Fabric. The data used are graduation data and stakeholders as participants (admin system) who will the use the application. Participants, namely bank admin, course admin (based on four regions) and auditor. The results shows developing web applications that implement the permissioned blockchain type consortium in Hyperledger Fabric and performance technology through system testing and data validation testing.
