This study was conducted to determine the characteristics of learning media by producing a thermodynamic physics e-book with local wisdom of STEAM-PjBL-based brick making process that is feasible, practical and effective in improving computational thinking skills in learning for grade XI high school students. This research is a development-research that uses the ADDIE model. Field trials were conducted using pre-test -post-test control group design. The assessment instruments, feasibility and practicality, were validated by 7 experts based on categories; material experts and media experts. A total of 107 students from 3 XI classes of SMA Negeri 1 Cepu became subjects in the field trial consisting of 35 students of experimental class 1, 36 students of experimental class 2, 36 students of control class. The data collection technique used was cluster random sampling. Data were collected through observation and interviews, questionnaires, and computational thinking skills test questions which were analysed by ANOVA test. The results showed that; i) the product of thermodynamic physics e-book with local wisdom of brick making process based on STEAM-PjBL has interactive characteristics, adds students’ skills, provides new learning experiences, and improves students’ computational thinking skills. Which is proven by the feasibility value in the category of very good on the material 3.85, 3.95 media, 4.00 practicality, and 3.96 readability. ii) proven effective in improving computational thinking skills as evidenced by the results of the ANOVA test which provides a significant difference in the application of the product to computational thinking skills as evidenced by the n-gain score of 0.66 (medium). The implications of this research are; i) to be an innovative solution in physics learning in encouraging character building and computational thinking skills that are relevant in the 21st century. ii) to support the existence of the Meredeka Curriculum and the strengthening of the Pancasila Student Profile through the integration of local culture and IPAS learning (physical science and socio-culture
