Due to the pandemic Covid-19, Department of Industrial Engineering, University of Diponegoro started requiring online learning for each subject using the Microsoft platform Teams. However, the use of Microsoft Teams has some problems. Firstly, the students complain of difficulties using the platform when the internet connection is limited. Secondly, the students have difficulty accessing Microsoft Teams because their hardware is not capable to run the Microsoft Teams. Thirdly, students also find it difficult to do flashback learning that has been done previously because access to video records cannot be accessed after 20 days after recording This study discusses the development of social media applications to support online learning, especially in computer simulation courses. To support computer simulation learning, this research develops applications based on social media (Telegram) and websites (Wordpress). Requirements Engineering methods is used to identify the users’ requirements, determine system requirements, design the application and perform application testing.
