In this research, a non-thermal plasma source has been designed and developed using the dielectric barrier discharge plasma production technique. It have the designed to have 2 model is planar electrode plasma model and plasma jet model. Generated using a DC power supply. The experiments were conducted in the room environment at atmospheric , and using argon gas to create plasma. [1,4,5] the tools of non-thermal plasma, the discharge level should be normal glow discharge at the atmospheric pressure. To get the result of the experiment it was necessary to modify many variable such as the gap, voltage, and gas flow rate to find the relation that was the cause of non-thermal plasma, and for developing the efficiency of non-thermal plasma.
