Results of the reliability of the variable X (brand equity) of 0.892 and Y (Decision Purchase) of 0.93. These results indicate the two variables is reliable. Test requirements analysis which transactions are carried out for the obtained regression equation is Y = 20.04 + 0,96X.

Then Lo F table (3.92), this proves that the mean regression. While testing the correlation coefficient of Pearson product moment obtained r xy = 0.694, then this means that there is a positive correlation between brand equity with Big Cola purchasing decisions. Then proceed with the coefficients significance test using the t test. The result is t = (10.25), While the table = the df = n-2 = 115-2 = 113 and the significance level was 0.05 (1.98), mean thitung> ttabel. It shows of this study is that there is a positive and significant correlation between brand equity with Big Cola decisions purchasing in Student Commerce Education Program at the State University of Jakarta.
