Laboratory materials testing courses often result in errors in the process leading to incorrect results. Making video tutorials aims to improve students' skills in practical laboratory material test subjects. This paper uses a research and development model from Thiagarajan. The 4D steps are to Define, Design, Development, and Dissemination. The resulting video tutorial consists of 12 video materials adjusted to the basic competencies in the practical material test. Media validation had carried out with a feasibility value of 91.54. From material experts 95.5 and the assessment of 12 video tutorials by students with an average score of 80.56. Based on the results of the study, it shows that the tutorial media containing 12 materials is very suitable for use in the material test practicum subject. © 2021 Author(s).
