Monitoring System and Auditing on Internet of Things (IoT) Based Electricity Using Arduino Mega 2560

Abstract

One form of energy that is most often and most widely used by people in carrying out their daily activities is electrical energy. The most common use of electrical energy is in industry or office buildings. To reduce the use electrical energy on a large scale, it is necessary to conduct an electrical energy audit. This research was conducted to produce an electrical energy control system design that is equipped with an automatic energy control system. The system built is called the Electrical Energy Monitoring and Audit System. The Electrical Energy Monitoring and Audit System is grouped into two groups, namely information systems and automatic control system that can provide output in the form of Energy Consumption Intensity value. The design of an automatic control system made using the Arduino Mega 2560 which is equipped with  Internet of Things (IOT), which can provide information in the form of data, perform data processing, and provide data output from the system mentioned above. The results of monitoring the use of electrical energy that was measured for two months at the Kedonganan Village Credit Institution (LPD) office with a building area of 755 m2 were 4232.73 kWh in August and 3782.09 kWh in September. The IKE values obtained are 5.6 kWh / m2 and 5.0 kWh / m2. and based on the IKE table the use of electrical energy at the Kedonganan an Institution for Village Credit of Bali (commonly known as LPD) was categorized as very efficient category.
