The aims of this study were: (1) to determine the feasibility of TikTok content-based learning media and (2) to determine the effectiveness of TikTok content-based video learning media in improving learning outcomes. The type of research is research and development Research and Development (R&D) with the product development model Alessi and Trolip. The research was conducted at SMK Negeri 2 Kisaran in class X students. The subjects of this study were 64 people consisting of 32 students for the experimental class and 32 students for the control class. The research results show; (1) the feasibility of TikTok content-based video learning media for product validation is 90%, for material expert validation it is 85.26% with very feasible criteria, for media expert validation it is 98.62% with very feasible criteria. (2) The effectiveness of TikTok content-based video learning media is effective compared to conventional learning media. There is a significant difference between the learning outcomes of students who are taught using videos based on TikTok content and conventional learning media. Obtained tcount = 2.18 and ttable = 1.66 so that tcount > ttable at a significant level ? = 0.05. So the learning outcomes of students who are taught with video learning media based on TikTok content have an effectiveness of 81.25% higher than conventional learning media with an effectiveness of 62.50%. The results of this study indicate that TikTok-based videos are effective in improving student learning outcomes.
