Based on the results of data analysis, this is proven based on the results of calculating the ttest of 3.493, while the ttable value at a significant level of 5% and d.b (degrees of freedom) 13 is 2.160. Based on these results, it can be concluded that the ttest value of the experimental group A (3.493) > ttable (2.160), so that the alternative hypothesis (Ha) in this study is accepted and the value hypothesis (Ho) is rejected.
