The Development of the Modern Physics E-book utilizes Flip PDF Professional to increase student independent

This study aims to develop an e-book on Modern Physics utilizing Flip PDF Professional, which is feasible, practical, effective, and can increase student learning independence. This Modern Physics E-book can make it easier for students to understand the material, attract interest, be practical, and can be used independently. The Modern Physics E-book will consist of audio image text and be made into several formats such as pdf, exe, HTML, and zip. The research was conducted at the State University of Medan Department of Physics in class B stamp 2020 and Class D stamp 2022. This research type uses the Research and Development R & D Borg and Gall model. The researchers used qualitative and quantitative data analysis techniques in this development. The results of the assessment and responses from filling out the questionnaire: (a) the percentage score of the material expert was 84% , and the percentage score of the media expert was 85% (b) the practicality of this media was 85.23% (c) ebook media can increase student independence with the results of 85% (e) from the results of the effectiveness test, it is found that the Modern Physics e-book media has an N-gain score of 0.41 in the medium category and an Ngain score (%) 41 % with a moderate interpretation. It can be concluded that the modern physics e-book media is very feasible, very practical to use and develop.
