Through research that aims to develop an interactive multimedia, it is hoped that it can become one of the appropriate learning media for students to use. This type of research is a Research and Development (RnD) method that adopts a 4D development model (Define, Design, Develop, Disseminate), with a focus on extracting data on Development (D) which contains an assessment of the feasibility of media products, with data collection techniques, namely non- test through a questionnaire, accompanied by a questionnaire instrument validation sheet. The data will be analyzed descriptively using percentage conversion in order to describe the feasibility of multimedia products.
