Intertemporal Efficiency Analysis of Indonesian Sharia Commercial Bank after Spin off Period 2013-2017: Data Envelopment Analysis (Window Analysis)

This study compares the operational stability of the Islamic Bank in Indonesia in post with a spin off research period 2013 to 2017 with the method of analysis with Window DEA or Intertemporal Efficiency Analysis. Window analysis is one of the development of DEA models that can measure the level of efficiency from time to time (intertemporal) observations on inputs and outputs from the DMU over several time periods, it is important to conduct panel data analysis where it focuses on changes in efficiency from time to time. income. The results are BRI sharia bank is the most efficient and stable out of the other several banks that is the research sample. This proves the concept of efficiency, which emphasizes the utilization of certain company inputs to achieve maximum output levels. In this case, BRI Sharia able to utilize inputs, namely TPF & labor costs to produce maximum output, namely financing and operating income.     Keywords: Islamic Bank Windows DE
