Normality Test, Normality Test, Classical Assumption Test which includes Multicollinearity Test, Autocorrelation Test, Heteroscedasticity Test, Hypothesis Test which includes Partial Significant Test (tTest), Simultaneous Regression Coefficient Test (Ftest), Determination Coefficient Test, Multiple Linear Analysis. The results of this study indicate that partially the shares have -ttest ttable (-2.725 -1.667) which means that the results have a significant negative effect on DPK. And inflation has -ttest -ttable (-4,852 -1,667) which means that inflation has a significant negative effect on Third Party Funds. And profit sharing and inflation simultaneously affect the Third Party Fund. This is evidenced by the value of Fcount Ftable (48.966 3.13). R2 shows that the percentage of contribution of the influence of independent variables on the dependent variable is 58.7% and the remaining 41.3% is influenced or or explained by other variables not included in this research model.
