Practicum based learning is required to provide opportunities for students in finding and applying concepts by observation. Student worksheets with a discovery learning model and equipped with AR video are needed as a learning tool, so students will be able to have good work in the laboratory and implementation of the practicum is effective. This study aims to produce LKPD (Lembar Kerja Peserta Didik or student worksheet) and AR (augmented reality) media that are videos related to the topic of practicum. The method used in this study is a research and development method with the Dick and Carey model approach. The feasibility test was carried out on the product using a Likert scale instrument. Feasibility test on media experts obtained a score of 89.95%, on material experts, obtained a score of 96.93%, on learning experts at 80% and obtained an average score of 88.96 % with a very proper interpretation. Next, a user trial was conducted on the product with respondents, which are at 54th Senior High School in Jakarta. Trials on teachers obtained a score of 97.61%, and trials on students obtained a score of 87.08%. The limited trials are done by doing pre-test and post-test on students. Limited trial results obtained an average n-gain score of 0.46. Based on the results of the feasibility test, user trials, and limited trials, it can be concluded that the developed student worksheet is very suitable to be used as a learning tool in physics practicum activities in Senior High School in 10th grade. © 2020 OmniaScience.
