Islamic banking takes part in the Indonesian economic and financial system which contributes to the dynamics of eeconomic growth. The number of Islamic banks in Indonesia, through its market share, is still quite small, namely 5.95% in 2019 of the total national banking market share. One of the main activities of Islamic banking is channeling financing through financing based on the type of use and business category. This study aims to determine the short-term and long-term contribution of Islamic banking to Indonesia's economic growth using the Vector Error Correction Model (VECM) method. The data used in this study are quarterly secondary data of real Gross Domestic Product (GDP) and financing based on the use and category of Indonesian Islamic banking business types, which consist of working capital financing, investment financing and consumption financing. The results showed that in the short and long term, the variable consumption financing had a significant negative effect on Indonesia's economic growth.

The purpose of this study is to analyze the influence of murabahah financing, profit-sharing rate and BI rate on the volume of Islamic banking mudharabah financing in Indonesia during the period of 2016-2018. The sample used in this study is all Islamic Commercial Banks in Indonesia in 2016-2018. The data analysis method used in this study is multiple linear regression to find the effect of each variable on the volume of mudharabah financing of Islamic banking in Indonesia. The results showed that simultaneously murabahah financing variables, profit-sharing rates, and BI reference interest rates influenced mudharabah financing. While partially murabahah financing variable and BI reference interest rate have a significant negative effect on mudharabah financing, while the interest rate variable has a significant positive effect on mudharabah financing. The limitation of this study is that it uses a few variables so that it has not been able to show the full variables that affect mudharabah financing volume.
