10. Validity and Reliability Test
Data validity test used in this research is Pearson Product Moment with the following formula:
The result of validity test is obtained by the total sample value for ᵗcount by 3.25, while ᵗtable by In the formula it is explained that if ᵗcount (3.25) > ᵗtable (1.85), then declared valid.

11. Validity and Reliability Test
Meanwhile, on the aspect of data reliability, this research uses Alpha Cronbach with the following formula.
After tested it was found that r11 = In the formula, it is explained that if the value r11 (0.913) > 0.6, then the instrument is declared as reliable.

12. Data Analysis Technique
The formulation can be seen in the following: n
P = _--- X 100 N
Description:
P = Percentage
n = value scores procured
N = total/maximum value score
20 - < 45 = Poor 45 - < 65 = Satisfactory 65 - < 85 = Good 85 – 100 = Excellent
