This study was a quasi-experimental study which aims to compare the increase in understanding of the concept of viscosity in a group that were assisted by a video tracker, ultrasonic sensor devices and manual observation. This research was conducted on first semester students at a university in the city of Semarang. The data obtained in the form of qualitative data in the form of interviews and quantitative data in the form of learning outcomes measured using essay questions. Based on the analysis of data that the use of video tracker in experiments to determine the viscosity coefficient provides the highest increase in comparison compared to experiments using a magnetic sensor and manual observation. In addition, an experiment assisted video tracker provides students with science process skills and was more interesting than assisted experiments with ultrasonic sensors and manual observation.
