This learning was strongly correlated with the cognitive domain. Based on some research that has been done, many students do not understand the concept of physics. This study aims to (1) produce a physics E-Book Assisted by iSpring suite 9 for harmonic vibration to optimize conceptual understanding in online learning of Public Senior High School Neomuti, and (2) to examine the reliability of the product in online learning of the school. The study adopted the 4D stages, started from the defining, designing, developing, and disseminating. The result of material and media validation were Analyzed quantitatively using the Four-Scale Assessment Criteria to determine the feasibility of the product. The validation and the judgment involved the material and media experts. The results showed that (1) the product, Physics E-Book assisted by iSpring suite 9 for harmonic vibration material based on conceptual understanding took form into an.apk file format, and (2) the developed e-book had an average score of reliability 6.39, categorized excellent. The finding showed that the e-book for physics was suitable for online physics learning during this COVID-19 pandemic. © 2024 Author(s).
