Design and Implementation of Smart Energy Management System Integrated with Internet of Things Technology in Engineering Faculty Unila

Energy management is carried out for planning, recording, monitoring, and evaluating continuously without compromising the quality of its production or service. This research aims to investigate the value of Intensitas Konsumsi Energi (IKE), as an important part of energy management activity, this research was held at Gedung A Engineering Faculty, University ofLampung (Unila). The source of electrical energy supplies from PLN with 66 kVA 3-phase power contract with a voltage of 380 Volts and P2 tariff group. Monitoring of energy consumption can be observed through equipment installed at working room and distribution panel, that already implemented with Internet of Things (IoT) technology. Its recorded data of lighting condition, temperature, humidity, and also electrical quantities such voltage, current, energy consumption. The Energy Management System developed using C program, PHP program, JavaScript, HTML programming languages. Based on data captured on March 8, 2021 shown the humidity average at 65%, lux 155, temperature 27°C, the maximum value of voltage at each phase was; phase R with 210 Volts, phase S with 208 Volts, and phase T with 195 Volts. The maximum value of current at each phase was; phase R with 38 Ampere, phase S with 41 Ampere, and phase T with 68 Ampere, while the energy consumption at phase R was 157534 Wh, at phase S was 245566 Wh, and at phase T was 182885 Wh, and total IKE value at that day was 0.151912, that means this building has efficient status energy usage.
