Abstract
Electrical energy is a very important requirement, interruption of electrical energy results in many
activities that are interrupted and even stopped. Saving electricity is a necessity, because in the future the supply of
electrical energy can be limited, the act of reducing the use of electrical energy is the right solution. Electricity
energy savings can be done in several ways, saving energy by turning off some electricity loads, saving energy by
installing energy-saving electrical loads, and saving energy that does not reduce or install energy-efficient electrical
loads, but reduces or even eliminates all electric power. or increase the power factor of the inductive, energy-saving
energy by installing capacitors in the circuit or electricity network, the installation of capacitors can also be useful
to optimize the power installed on the electricity grid of PLN customers. The installation of capacitors on the
electricity network must not be arbitrarily installed must pay attention to the nature of the electrical load, which
means that not all electrical loads can be repaired and must be repaired by the power factor. From this description
the authors build a power factor control prototype, this system is built to control the capacitors installed on the
electricity network, so that the capacitors are not installed or installed in accordance with what is needed on the
electricity network, in addition to this the capacitor size must also be in accordance with the requirements on the
network, so the microcontroller will direct how many capacitors must be installed with the help of a relay module. In
order for the microcontroller to be able to control the relay module there must be data coming in, namely by
installing multiple PZEM-004t measuring devices, from the measurement data it can be known whether the network
requires capacitors or not, and if capacitors require how much capacitors must be installed on electric network.
With this system, consumers can optimize power in accordance with the amount of installed power that we buy from
PLN, and besides that we can find out the amount of voltage, current and power used at that time.
