The Influence of Bi Rate and Inflation on Mudharabah Deposits at Jabar Banten Islamic Bank

This research was conducted to analyze the influence of
BI rate and inflation on mudharabah deposits in Jabar Banten
Islamic Bank. The data used in this study are monthly data from
January 2015 to December 2017. The analysis technique used is
multiple linear regression and hypothesis testing using t-statistics
to test the partial regression coefficient with a level of
significance of 5%. Besides that, a classic assumption test is also
conducted which included normality test, heteroscedasticity test,
autocorrelation test and multicollinearity test. During the
observation period, from January 2015 to December 2017, the
results of the study do not find any classical assumptions
deviations. This indicates that the available data met the
requirements for the use of multiple regression equation models.
The results show that BI rate has a significant negative effect on
mudharabah deposits, with a level of significance smaller than
5%. Inflation has a positive and insignificant effect on
mudharabah deposits, with a level of significance greater than
5%
