Abstract

The purpose of this study is to describe the concept of understanding and critical thinking skills in Hygiene and Sanitation subject course. This study is an experimental study that uses experimental and control design. Its sample was students of Politeknik Negeri Bali majoring in tourism in the fourth semester of the 2021/2022 academic year which was determined by non-probability sampling with a cooperative learning model. Instruments used to collect data in the form of concept mastery test sheets and critical thinking developed based on indicators of Hygiene and Sanitation learning materials on the sub-topic of waste and the environment. Meanwhile, the critical thinking skills test developed based on argumentation analysis indicators showed an average experimental class score of 85.33% with high criteria and a control class of 33.33% with medium criteria. While the mastery of the concept of the experimental group is 81% with high criteria and the control class is 33% with medium criteria. The results of the t-test for mastery of concepts and critical thinking skills show that the experimental class is significantly higher than the control class with a value of tcount = 4.28 > ttable = 1.671 then Ho or the hypothesis is rejected. Thus it can be concluded that the use of multimedia is more effective in increasing mastery of concepts and critical thinking than learning without multimedia or conventional learning on Waste and Environment material.
