Recently, the efficiency of electrical energy is one of big challenges in the world. The needed energy is very huge; meanwhile the sources of energy are limited. Many researchers have been trying to find solutions for increasing the energy efficiency. One of ways is to monitor the use of the energy easily so we can reduce the energy usage. This paper proposes a system for monitoring energy usage by using Internet of Thing. Such system is called as Energy Internet of Things (IoT) based Database Management System (EDBMS). All buildings are supplied by Unit 2 Outgoing Transformer in the State Polytechnic of Malang which collects data of the used energy by using smart energy meter. It uses router LAN in UPT PP for sending the data from all buildings to the cloud, and displaying the received data on a web page. The collected data will be used for the analysis of power quality. Based on the result of the harmonic monitoring that shown the value are still in the standard range because the limitation of allowable THD current is 15%. And based on IEEE STD 446-1995, the standard for three-phase load imbalance is as much as 5-20% maximum for each phase. Meaning, Unit 2 Outgoing Transformer is out of standard or it does not comply with the standard.
