Development of A Tutorial Video on the Application of Centrifugal Chromatography for the Separation of Fractions from Campnosperma Auriculatum Root Extract

The purpose of this research is to determine the feasibility of a tutorial video on fraction separation using centrifugal chromatography. The tutorial video of fraction separation using chromatography was made to document the stages of using centrifugal chromatography in separating fractions of white stretched root extract. The separated fraction is derived from the root extract of the Campnosperma auriculatum. The research method used is development method, which involves applying the ADDIE model at the ADD stage. The research instrument used is a feasibility assessment sheet on media and material aspects and data analysis using a Likert scale. The data collection technique used was indirect communication with a questionnaire in the form of a questionnaire and validation sheet. The feasibility of video tutorials was assessed by two material experts and two media experts. This study focuses on a video tutorial on centrifugal chromatography-based fraction separation. The final results of the assessment showed that both the material and media aspects received a score of 100%. Thus, it can be concluded that a video tutorial on fraction separation using centrifugal chromatography is very feasible. This video tutorial is expected to be an educational reference for researchers and students in learning fraction separation techniques using centrifugal chromatography.
