Based on the results of this study, it is known that the results of the t test for capital structure as proxied by long term debt to equity ratio have no effect on profitability as proxied by return on equity but the activity ratio proxied by total assets turnover has a positive and significant effect on profitability. The results of the F test show that the capital structure and activity ratio have a joint effect on profitability. for the results of the moderation regression test of model 1, it is known that the liquidity proxied by the current ratio is able to moderate but weaken the relationship between capital structure and profitability, but the results of the regression test of model 2 show that liquidity is able to moderate and strengthen the relationship between the ratio of activity to profitability
