From the data collection that has been obtained, the calculation resulted in the average value of the cognitive domain of the experimental class of 75.38 and the average affective domain of 77.38, while for the control class, the cognitive domain averaged 65.00 and the average affective domain of 71.03. Based on the results of data analysis, it was found that cognitive domain resulted in a value of t_-count&gt; t_-tabl_ewere 2.96 &gt; 2.00 with the effect size 0.8 or 79% (a quite high category), while the affective domain was t_-count &gt; t_-tabl_e which was 4.81 &gt; 2.00 with the effect size 1.23 or 88% (high category).
