Capital Adequacy and Liquidity Analysis of Operating Efficiency in Banking Issuers Listed on the Indonesia Stock Exchange

— Efficiency measurements carried out by banks are faced with the condition of how to get the optimal level of output with the existing input level, or get the minimum level of input with a certain level of output. Identification of input and output allocation can be analyzed further to see the cause of inefficiency. There are several factors that affect the efficiency of certain operations, namely capital adequacy and liquidity.
