The Development of Hands-On Lab Platform Using Container-Based Virtualization Technology

Practicum allows students to develop practical skills relevant to their field of study, gain real-world experience, and enhance their understanding of the topics studied. However, the resources required for practicum often require significant cost. Limited resources in the laboratory resulted in a limited number of students accessing it as well. Virtual lab with container-based virtualization technology is one solution to reduce resource usage and simplify the laboratory environment while still providing a real system for the students' experience. This research uses container-based virtualization technology with Docker to provide the hands-on lab. The hands-on lab requires two main components: Open edX and the hands-on lab server. Students can carry out learning activities through hands-on labs in the XBlock plugin from LMS (Learning Management System) Open edX. The results of this research are based on the functional test aspect that shows the hands-on lab can run according to its function and coordination among system components works correctly. Non-functional test will also quantify the hands-on lab's time behavior and resource utilization. The non-functional test results show that the time behavior is quite responsive, and resource utilization is quite good, with a CPU usage of 0.51% and RAM usage of 1.12%.
