Abstract
Molecular biotechnology is a high-level course that requires other courses as prerequisites. This course is taught in theory and practice, but in its implementation, practical activities are difficult to do due to limited facilities and infrastructure so that other alternatives are needed, one of which is to conduct virtual practicums. This study is an experimental study that uses different campuses with the same treatment. The sample of this study amounted to 71 5th semester students. Data were analyzed descriptively and inferentially with SPSS 22 for windows. The results showed that students^ procedural abilities were 56.49 percent in the moderate category while students^ declarative abilities were 61.78 percent in the moderate category. Overall, students^ conceptual mastery ability after treatment was 60.31% in the moderate category with an increase (N-Gain) of 0.43. Based on the hypothesis test, there was a significant difference between the pretest and posttest after the treatment was given a sig value (0.00) > a value (0.05). So it can be concluded that molecular biotechnology lectures with the help of virtual labs can improve students^ procedural abilities, declarative abilities and conceptual mastery.
