This research aims to determine the increase in students' interest in learning and understanding the material after using student worksheets, provide an overview of optimizing digital content and assignments for teachers and students, as well as develop the form and function of student worksheets in a more complex manner by involving digital media in the form of AR Video and QR Code integrated Form Timer Exercises. The research model uses a 4D model (define, design, develop, and disseminate). The test subjects were 25 class X students at Senior High School 1 Pelalawan. Data sources were obtained from interviews, questionnaires for needs analysis, and results questionnaires. The data in this research were analyzed using qualitative descriptive techniques to analyze interview information and quantitative analysis techniques to process data in questionnaires for needs analysis and result questionnaires.
