Presicion Air Conditioning Equipment System (PAC) is important in operational activities to maintain the temperature and humidity of every company that has a large and critical server unit both banking, industrial and service companies. This research discusses to study and analyze the PAC engine by using the Overall Equipement Effectiveness (OEE) method. It is expected that using quantitative and qualitative methods can test the OEE values of each machine and what factors influence it by means of a fishbone Presicion Air Conditioning Equipment System (PAC) is important in operational activities to maintain the temperature and humidity of every company that has a large and critical server unit both banking, industrial and service companies. This research discusses to study and analyze the PAC engine by using the Overall Equipement Effectiveness (OEE) method. It is expected that using quantitative and qualitative methods can test the OEE values of each machine and what factors influence it with a fishbone diagram analysis and 5 why. The results showed that the value of OEE on each machine is still below world class standards of 85%.
