This study aims to produce a valid and effective e-pocket book media development product for bacteria material to improve learning outcomes, motivation, and curiosity of students in class X Mathematics and Natural Sciences. This research uses Research and Development research. The data taken include validity, practicality, and effectiveness (motivation and curiosity and learning outcomes). The data collection technique was carried out by non-test (questionnaire) and tests. Data analysis techniques include validity analysis, practicality analysis, and effectiveness analysis. The e-pocket book was tested at SMA PL Don Bosko Semarang for a small-scale test in one class, namely X MIPA 1 and a large-scale test in 3 classes, namely X MIPA 1, 2, and 3. The results showed that the e-pocket book media was declared very good. Valid, based on the percentage of scores obtained by media and material experts, namely 93% and 85%, with an average of 89%. It is stated to be very practical, based on the acquisition of percentage scores by teachers and students, namely 95% and 90%, with an average of 93%. It was stated that it was effective in increasing students' motivation and curiosity, based on the acquisition of the average score percentage per class ≥70%, namely X MIPA 1 = 80%, X MIPA 2 = 78%, X MIPA 3 = 79%. The results of the pre and posttests resulted in an average N-gain score for each class of more than 0.30 and less than 0.70, namely X MIPA 1 = 0.47, X MIPA 2 = 0.57, X MIPA 3 = 0.61 scale currently. Based on the results of the study, it can be concluded that the e-pocket book material developed by bacteria is effectively used as a learning media in class X MIPA SMA PL Don Bosko Semarang to improve student learning outcomes, motivation, and curiosity.
