One of the facilities from PLN for customers is the addition of power within a certain period of time for customer events that require more power than their contracted power subscription. PLN will install a special kWh meter, called a party kWh meter, to calculate the customer's power usage during the event. However, due to the amount of work that exists in PLN, and the number of officers that are not proportional to the demand for parties, sometimes PLN does not immediately disconnect and dismantle the party material, which can be detrimental to customers because the bill on the party kWh meter continues to be calculated without them knowing and causes problems for PLN. Therefore, the following research was conducted with the aim that this tool can monitor energy usage by customers and PLN automatically using the PZEM-004T energy sensor module with an average test result of no more than 5%. This tool can also provide supplementary billing information to customers and PLN when kWh usage exceeds emin with a maximum delivery delay of 3 seconds. In addition to monitoring energy consumption and supplementary bills, this tool can automatically disconnect remotely when the party is over with a relay disconnection delay of no more than 5 seconds.
