Development of Problem-Based Physics E-Book on The Topics of Work And Energy to Improve Students' Conceptual Understanding and Digital Literacy Artanti, Francisca Happy Widiatmono, Restu Jumadi, Jumadi This study aims to develop an electronic book (e-book) based on the Problem-Based Learning (PBL) approach to enhance students' conceptual understanding and digital literacy on the topic of work and energy. Responding to the growing demand for interactive and student-centered learning media in physics education, the e-book is designed to serve as a learning resource that fosters engagement in problem-solving and critical thinking. The research adopts the ADDIE development model, comprising Analysis, Design, Development, Implementation, and Evaluation, and applies a quantitative approach using a one-group pretest-posttest design. Participants in this study were tenth-grade students from State Senior High School 9, Yogyakarta. Data were collected through the use of the developed e-book, conceptual understanding tests, digital literacy questionnaires, and student response surveys. Validators rated the e-book as “highly valid” and suitable for use. The implementation results showed a significant improvement in students' conceptual understanding, with an N-gain score of 0.71, which falls into the high category. Additionally, there was an improvement in digital literacy, with an N-gain score of 0.66, which also falls into the high category. The effectiveness of this e-book was also tested using a T-test and showed significant improvements before and after learning for both variables. Additionally, students responded positively, finding the e-book engaging, easy to access, and beneficial in supporting their learning process. These preliminary findings indicate that the PBL-based e-book has the potential to be an effective learning tool for high school physics education.    Keywords: e-book, problem-based learning, work and energy, conceptual understanding, digital literacy.
