From the results of the functional requirements analysis described in the block diagram and the system plan described in the activity diagram. The system implementation uses the native React framework, JavaScript programming language, and Firebase database to store the data. To overcome these problems, we need a system that makes it easier for people to learn and add knowledge. Therefore, the mobile application-based course management system that we created is expected to be an efficient and effective system for use by many people. The results of our test were carried out with two different operating system on IOS and Android and can run functionality and responsively. The result of the user questionnaire shows that 85% of the public and 82% for customers from informatics student backgrounds who show indicators of being quite satisfied.
