Learning Criminology has a theoretical learning character, resulting in a lack of use of media which results in less than optimal student activities, especially student engagement. The right media used in increasing student activities is a hybrid flipbook. This media can be equipped with material, video, audio, and visuals. This research uses the Classroom Action Research method, with the stages of planning, implementing, observing, and reflecting. The research subjects were students of the PPKn FKIP Study Program, Universitas PGRI Yogyakarta. The exposure of the research was done by using a quantitative descriptive technique. The success indicator is set at 80% of the achievement indicators from student engagement. The indicators used are three aspects of student engagement, namely cognitive, emotional and behavioral aspects. Based on the results of research on increasing student engagement using flipbook hybrid media in the Criminology course, it can be concluded that: the implementation of classroom action research has increased student engagement competence in the application of hybrid-based media flipbooks. This can be seen from the condition of the results achieved in the initial pre-study, namely 59.29%, increased to 73.21% in the first cycle, and then increased again to 85% in the second cycle. The use of flipbook hybrid learning media can improve three main elements in student engagement, namely behavioral, emotional and cognitive factors. Based on the seventh-grade action research, six indicators of student engagement have been achieved with an indicator of 80% achievement. This research can be developed more maximally by increasing the attractiveness of learning media to increase student activity.
