This study aims to develop a mathematics e-module assisted by a flipbook maker based on a problem-based learning model on the material of valid, practical, and effective quadratic equations. The type of research used is research and development with the ADDIE model, namely: Analyze, Design, Develop, Implementation and Evaluation. The subjects of this study were grade VIII students at SMP Negeri 5 Tombolo Pao. The instruments used were validation sheets, learning management observation sheets, student activity observation sheets, student and teacher response questionnaires and learning outcome tests. Based on the trial results, the validation results of the e-module were 3.97 in the valid category. Practically, based on the analysis of teacher responses to the e-module, a positive response of 100% was obtained, while the analysis of student response data to the e-module found that 95.27% of students gave positive responses. Effective based on learning management, an average of 3.7 was obtained in the very good category, student activity was in the very good category, namely 75%, and the learning outcome test was in the high category with an average test score of 86.5. In the trial stage, the e-module assisted by a flipbook maker based on a problem-based learning model on the quadratic equation material met the valid, practical and effective criteria.
