This research was conducted on the low scientific literacy abilities of students in Indonesia based on PISA, middle school students in Medan based on PUSMENDIK data, and the lack of TPACK-based teaching materials that measure students' scientific literacy. This research aims to develop a feasible, effective and practical E-Book to improve students' scientific literacy skills on the human digestive system.
