Deska Kartiwi. (2026). Development of Massive Open Online Course (MOOC) Content to Enhance University Students' Chemical Literacy Regarding the Selection and Use of Safe and Appropriate Skincare Products and Cosmetics. [Undergraduate Thesis, Department of Chemistry Education, Faculty of Teacher Training and Education, Universitas Syiah Kuala]. Supervised by Dr. Dra. Sulastri, M.Si. and Dr. Syahrial, M.Si. Chemical literacy plays an important role in helping university students understand the chemical ingredients contained in skincare and cosmetic products, enabling them to select and use these products safely and appropriately. However, students' chemical literacy regarding skincare and cosmetics still needs to be improved. This study aimed to (1) develop a feasible Massive Open Online Course (MOOC) as a learning medium, (2) analyze the improvement of students' chemical literacy after using the MOOC, and (3) describe users' responses to the developed MOOC content. This study employed a Research and Development (R&D) approach using the ADDIE model, which consists of the Analysis, Design, Development, Implementation, and Evaluation stages. The research subjects consisted of three expert validators and 35 students from science and non-science study programs at Universitas Syiah Kuala who participated in the implementation trial. The research instruments included expert validation sheets, pre-test and post-test instruments, and a user response questionnaire. The data were analyzed using descriptive analysis, the Wilcoxon Signed-Rank Test, and N-Gain analysis. The results showed that the developed MOOC content achieved validation scores of 94% from the material expert, 95% from the media expert, and 84% from the communication expert, all of which were categorized as highly valid. The results of the Wilcoxon Signed-Rank Test indicated an Asymp. Sig. (2-tailed) value of 0.000 (
