The security and confidentiality of data is very important because the data can be used by people who are not responsible for committing crimes. This of course will be fatal for the data owner in the event of data misuse. Faculty of Engineering, is one of the faculties at Muhammadiyah University of Ponorogo that implements a lecture management system in the form of practicum and digital-based internship. However, the implementation of the security of academic data stored on the system is still lacking because it only applies basic authentication. Therefore, in order to improve the security of academic data, it is also emphasized the use of the HMAC (Hash-Based Message Authentication Code) algorithm to improve system security in terms of authentication and authorization. The results of this research can improve the security of the lecture management system, so that later it can produce software that is tested both in terms of functionality and system security.
