The corona discharge with a multi-point-toplane configuration has been analyzed, especially on its electrical characteristics. The electrical analysis of this type of plasma reactor is macroscopically similar to the IV characteristics. By using the I-V. characteristics and the formulation which has been modified to include a factor of the number of point electrodes, the mobility of the charge carriers has been determined. The mobility that has been determined is the mobility of positive nitrogen ions according to the type of positive corona discharge. At the cathode in the form of a copper plate, a sample of rice is placed so that the sample is subjected to irradiation, the treatment of plasma species can cause accelerated rice growth. Ion mobility is carried out under atmospheric conditions with variations in the distance between the electrodes and. I-V characteristics are different because of the different distances so that the mobility is also different. The value of mobility obtained with the sample between the electrodes is always higher than without the sample rising. Ion irradiation was carried out by corona discharge with a high voltage (HV) at 4 kV DC and a current of 150 A at a distance of d = 2 cm. The rice has been irradiated were a premium types from Demak Regency, Central Java Indonesia. The results showed that plasma radiation can increase the growth of premium rice which includes the percentage of germination speed, root length, stem length, and rice mass. The optimum irradiation time for the growth of premium types of rise observed for 15 days was 30 minutes. The results showed that the total nitrogen content increased proportionally with the length of irradiation time. The high nitrogen content in rice seeds can be caused by the infiltration of positive nitrogen ions. It is suspected that nitrogen ions are deposited into rice so that rice has an optimum nitrogen content which can accelerate growth.
