A large load imbalance is caused by the use of single-phase loads in a three-phase system, and poor harmonics are caused by non-sinusoidal loads, which result in losses in the network and poor quality of power distribution. This study aims to monitor and analyze load balance and harmonics in the Graha Polinema Building at Politeknik Negeri Malang. The research is a survey and case study using primary data obtained through direct measurement using a Web-Based Power Quality Meter (PM 5110) to gather data from each SDP panel, and secondary data through observation. From this study, the highest current imbalance value of 133.50% was found in the North 4th Floor SDP Panel of the Grapol Building, exceeding the IEEE 1159-2009 standard, which sets the limit for load imbalance at 30%. Current Harmonic Distortion (IHD) occurred in 8 SDP panels, except for the North and South Water Pump Panels. Total Demand Distortion (TDD) for all panels was within the standard limits. Total Harmonic Distortion (THDv) for all panels was also within the standard limits, with the highest value of 2.37% found in the North 4th Floor Panel.

Energy audits are evaluation activities carried out to determine the condition of the energy used in a system. Audits are carried out to provide the efficiency of an electrical system. The first energy audit conducted was the initial energy audit. By using the specifications of the installed electrical system and using monitoring data. Followed by a detailed energy audit, to determine the condition of a more specific electrical system. The data used is measurement/monitoring data, and data calculations are then compared with the provision of the electricity standard. In calculating the intensity of energy consumption in the initial energy audit process, the IKE Fave Hotel results were still by the standards with an IKE value of 213.59 kWh/m2. Meanwhile, based on the results of a detailed energy audit, it was found that the lighting system and cooling system were not up to standard because the lux results for several rooms showed results that were less than the lux standard. Thus, it is necessary to provide recommendations for improvements to the lighting and cooling system. Providing lighting recommendations can use dialux as a calculation comparison. In the lighting system, it is necessary to replace some of the lamp specifications installed because they are far from standard values. This also needs to be done on the cooling system, by replacing the installed air conditioner according to existing calculations. This replacement was carried out to save energy for the continuity of the hospitality industry process at Fave Hotel Malang.
