<![CDATA[The teaching materials used by teachers in science learning only consisted of textbooks and student worksheets (LKS) provided by the government, so students were less interested if learning only used these two teaching materials. Therefore, STEAM-based teaching materials are needed to increase students’ interest in science learning. This study aims to measure the feasibility level as well as student and teacher responses toward the STEAM-Based E-Book (Science, Technology, Engineering, Art and Mathematics) on the topic of Elements, Compounds, and Mixtures at SMP Negeri 13 Pontianak. The method used in this study was Research and Development (R&D) and employed the ADDIE development model. Data collection was carried out through literature studies, observations, interviews, feasibility tests, and response questionnaires. The developed e-book was validated by experts including aspects of language, media, and material. The response test was conducted on 2 science teachers, 10 students in the small-scale trial, and 20 students in the large-scale trial. The feasibility test results showed that the percentage of feasibility of the developed e-book in the language aspect was 97%, in the media aspect was 96%, and in the material aspect was 100%. The average percentage of teacher responses toward the developed e-book was 84% (very feasible), while student responses in the small-scale trial were 82% and student responses in the large-scale trial were 84% (very feasible). Thus, the STEAM-Based E-Book (Science, Technology, Engineering, Art and Mathematics) on the topic of Elements, Compounds, and Mixtures is highly feasible to be used and received very good responses from teachers and students.]]>
