Technological developments demanded student-centered learning-based learning. The development of multimedia-based modules was expected to improve the learning process and existing learning resources. Chemical equilibrium material was one of the materials that were difficult to understand and had a broad scope and limited discussion time. Therefore, learning modules were needed that could be easily accessed and understood. This study aimed to produce appropriate multimedia-based learning modules easily understood by students. The research method used was Research and Development (R&D). The developmental design used by Borg and Gall. The feasibility of multimedia-based modules was obtained from the validation results of 3 experts, namely material experts, media experts, and linguists. The module was tested on teachers and students at school. The results of the expert validation stated that multimedia-based modules on the subject of chemical equilibrium were considered feasible from the categories of material, media, and language. The results of the multimedia-based module trial on the material of equilibrium for teachers and students received an assessment in the Very Good category.
