Electrical energy savings by utilizing internet-based automatic monitoring and control of things

Utilization of modern technology is almost inseparable from the use of electrical energy. There is often the use of electrical energy that is actually not needed (wasteful), wasteful use of electrical energy results in increased costs, increased power supply, which has an impact on increasing equipment capacity, the problem of saving electrical energy has been widely discussed but saving electrical energy is easy and can be controlled automatically and can be monitored remotely still needs to be improved. Saving electrical energy can have an impact on cost savings, as well as prevent a crisis in the supply of electrical energy. According to data from the Ministry of Energy and Mineral Resources, the installed capacity of power plants for the 2018-2020 period increased by 2.34% per year. The distribution of electricity to customers in the 2018 – 2020 period has increased by 1% per year. Monitoring and controlling electrical energy can be done using controls using sensors and can be monitored and controlled remotely based on the internet of things. This study aims to design and manufacture a prototype tool that functions to monitor and control electrical loads in real time from a distance based on the internet of things and by utilizing sensors can also help turn on and turn off electrical loads as needed. The method used is through the stages of Analysis, Design, Development, Implementation, Evaluation (ADDIE). The results of the study show that the designed and manufactured tools can monitor electrical loads whether they are on or off and can turn on or turn off electric loads automatically with the help of sensors and actuators and can also be controlled remotely via smartphones, laptops, computers or tablets. Future studies are expected to be able to control electrical parameters including voltage, current, frequency, real power, reactive power, apparent power, and power factor. The expected impact of this research is that it can control electrical energy automatically easily and can control it remotely and save electricity usage.
