Trend in the development of Islamic banking industry in Indonesia in the last decade experienced a very significant development both qualitatively and quantitatively. The attractive development that is to be a pride for stakeholders of Islamic banking considering that Indonesia can be said too late, not to say left behind in responding the development of sharia-based industries and businesses if compared to other Muslim countries. However, the performance of Islamic banking financial institutions in Indonesia, slowly but surely, shows tremendous growth, even in certain level, can defeat neighboring country, Malaysia, which had long been working on Sharia-based financial sector.
