The 21st-century skills require a minimum of 4C skills. Learning media also need to apply TPACK (Technological, Pedagogical, and Content Knowledge) framework. This article describes the research and development result of the TPACK implementation in a high school physics textbook to enhance 4C skills for students’ 21st-century skills. The obtained physics textbook uses dick and Carey’s research and development model. Technology in this textbook using augmented reality media. The TPACK physics textbook assisted by AR (Augmented Reality) had produced for the 11th grade even semester at mechanics wave concept to enhance students’ 4C skills. The book feasibility received an assessment from the content expert, media expert, and pedagogical expert using the continuum scale 4 in the questionnaire instrument. The final result shows the implementation of TPACK in a resulting high school physics textbook product is proper to enhance 4C skills as a provision for 21st-century skills.
