Abstract: This study discusses the analysis and realization of electrical power quality improvement of office building with case study at Universitas Muhammadiyah Yogyakarta (UMY) rectorate building. One of the important variables in determining the electrical power quality of a system is the load power factor on the consumer side. The power factor depends on the type of load being served. In office buildings generally, the largest electrical load is a cooling device. This air conditioner in its operation using electric motor components. An electric motor is an electrical load that has a bad power factor. With this fact, the electrical load of electric motors on the air conditioner contributes greatly to the overall bad power load factor. In this study, a case study on electrical power quality audit at the UMY rectorate building was conducted. Based on the audit results obtained data that the power factor of the building is still below the standard, so, it needs to be done power factor improvement. The results showed that the calculation of capacities and types of capacitor bank are useful to improve the power factor of UMY rectorate building.
