Abstract
Due to COVID-19, media is needed so that students can continue to carry out practical activities at home to improve their understanding of chemical concepts. This study aimed to develop and determine the quality of a simple practicum video on redox material. This research is development research (R&D) with a 4D model (Define, Design, Development, and Disseminate), but this research is only up to the development stage. This simple video practicum on redox material contains the redox process on nail corrosion, the redox process on betadine with vitamin C, and the redox process on Onions with potassium permanganates. The product is assessed by one material expert, one media expert, four reviewers, and ten class X students respond. The results of the product quality assessment by material experts, media experts, and reviewers (senior high school chemistry teachers) get a percentage of 97.14%, 90%, and 91.81%, with a very good category. Then, the results of student responses obtained a percentage of 95% with a very good category. Based on this assessment, it can be concluded that simple practicum videos on redox material can be used as an alternative source of practicum during the COVID-19 era.
