Digitalization is one of the fields that affect the 5.0 revolution civilization towards world mobility. In fact, there are many conversions of learning media from manual forms to digital variations, in the learning process. Learning media as a tool that helps the learning process in presenting material in an interesting way so that the learning situation becomes effective, efficient, active and easily understood by students. This study aims to determine: validity by experts, feasibility by teachers and response by students to the design of web-based science learning media at the high school level. The method used in this research is R&D using the ADDIE development procedure, where this model consists of 5 stages, namely analysis, design, development, implementation, and evaluation, but this research is limited to the development stage. The instrument in this study is a validation questionnaire, feasibility and response. The results of this study are (1) obtained validity test results from media experts as a whole average percentage of 91.1% in the "very valid" category, and material experts of 93.7% in the "very valid" category. (2) the teacher feasibility test amounted to 88.4% so that it was concluded that the category "very feasible" and "feasible". (3) the average percentage of student responses obtained was 84.3%, it can be concluded that each school is in the "interesting" category. The results of this study indicate that the learning media is interesting.
