Diploma certificate and transcript forgery is a serious issue in education. The government is still finding the best way to prevent and minimize this issue in the future. The diploma certificate and transcript are very easy to duplicate, not only from third parties. Even the university can easily produce a fake diploma certification and transcript for their benefit. Blockchain technology is a new technology and now can be used to prevent the fake graduation documents. This research shows the simulation of blockchain technology used (Multichain) for data recording of academic transcript as one of the graduation documents. FGD has been carried out by inviting several reputable universities to validate the prototype. As a result, the FGD participants validated the prototype and agreed if it possible to be implemented in university, especially for recording the academic transcript data. Recording the academic transcript on blockchain technology can contribute to prevent forgery.
