<![CDATA[This study aims to determine the queuing system for optimization of teller services at Bank Negara Indonesia, Slamet Riyadi Solo Branch Office. The data used in this study is a direct observation of the object of research / observation. The sampling technique uses the Leddy formula because the population cannot be known. The data analysis technique used is manual calculation using the queuing system formulas of many single-stage channels (multiple channel-single phase). The results of this study indicate that teller services for customers using 4 counters are not optimal because ≥ 5 minutes or 31,16 minutes occur at counter 4, while the time to wait in the queue is compared to the company's standardization of 5 minutes, so researchers do calculations using additions become 5 counters and can only get optimal results, namely ≤ 5 minutes or 0,18 minutes occurs at counter 1.]]>
