The COVID-19 pandemic forced STIE & STMIK Jayakarta to use the distance learning process for students. Institutional policies to use the Google Workspace for Education application as a Learning Management System (LMS) are deemed appropriate, but they are still experiencing difficulties in learning computer practicums. The use of the Google Forms feature as a computer practicum worksheet is considered less effective in increasing student independence in completing their practicum assignments. This study aims to design a web-based learning application that uses the Predict-Observe-Explain (POE) learning model which has advantages, such as being used to express students' initial ideas, generate discussion, provide information to lecturers about students' thoughts and motivate students to want to explore concepts, and arouse the desire to investigate. The application development method in this study uses Extreme Programming (XP) as an agile approach model for responsive application programming, with user needs that are rapidly changing and always changing. The result of this research is the design of a web-based application that uses a POE card as a computer practicum worksheet with a web page link from the LMS so that it can accommodate the learning outcomes of computer practicum courses.
