The method in this study is a true experiment, which is areal experiment. With the design of the Pretest-Postest with Control Group, which can be expanded by involving morethan one independent variable, the treatment of more than one group with different forms of treatment? Data analysiswas performed using the statistical analysis method SPSS program version 23. To find out whether there aredifferences or not before the normality and hogenicity test of the data was carried out, if the data were normallydistributed and homogeneous, the ANOVA version was tested followed by the Tukey HSD test, if it was not normal,use mann widney-test, with a 95% confidence level H1 is accepted, if the value of p value is
