【 摘 要 】

Plasma research on used oil (waste cooking oil) processing into biodiesel using Dielectric Barrier Discharge (DBD) has been conducted. Plasma technology can process used oil into biodiesel without using chemical catalysts. The DBD reactor in this research was formed by inside electrode, barrier and outside electrode components. The inside electrode is screw stainless steel with diameter 0,79 cm. The barrier is pyrex tube with thickness 0,25 cm. The outside electrode is copper wire which is wound into the pyrex tube. Plasma was flowed by argon gas with debit rate 2 L/minutes. In plasma reactor was connected AC voltage 1,6 kV. The oil mixed with methanol by volume ratio 6:1. Both materials were inserted into a reactor with the time variation of 30, 60, 90, 120, 150 min. The optimum result was obtained at 30 minutes treatment. The oil which was resulted has density 0.87 g/cm3, viscosity 4.1 mm2/s, acid number 0. 56 mg KOH/g, iodine number 31.64% -mass and 16.01% are mono-alkyl ester compound, and it was classified in National Indonesian Standard (NIS).
