The design of hypothesis testing uses classical assumption test, simple linear regression analysis, correlation coefficient analysis, coefficient of determination analysis, and hypothesis testing using t test. From the test results it can be concluded that both NPF partially influences ROA but not significantly. As for the BOPO also partially influences but not significantly on ROA. Simultaneously it can be seen that the calculated f value of 2.727 with a significant level of 0.094. Where the significance level is greater than 0.05, while the calculated f value of 2.727 is greater than 3.59, it can be concluded that there is a significant but not significant relationship between the NPF (X1) and BOPO (X2) variables simultaneously against (ROA) (Y).
