Abstract
This research presents a prepaid electric energy consumption system via online top-up system and a notification through Line application. The system is composed of two parts: the prepaid machine and the electric power consumption-control machine. The prepaid machine is used for topping up money for the electric power users and then the information of the top-up money will be sent to the electric power consumption-control machine via online system. The electric power consumption-control machine is used for controlling the electric energy consumption of the electric power users. This machine can notify the users of the amount of top-up money and the amount of electricity that can be used via Line application. In addition, the electric power users can verify the amount of money and the amount of electricity that can be used on LCD monitors attached to the electric power consumption-control machine. The efficiency of the system was tested using eight electrical appliances namely: an electric fan, an incandescent lamp, an electric rice cooker, an electric jar pot, a steam iron, a refrigerator, an electric pan, and an electric kettle. The electric power consumption was measured by kilowatt-hour meter compared with the proposed electric power control system. For the experimental results, it was found that the average error of the electric power consumption was at 0.37 %. In addition, the notification system that notifies the electric power users of the existing the amount of money, the amount of electricity that can be used and other information is proven effective.
