Abstract
The processing of palm oil into crude palm oil (CPO) produced palm oil mill effluent (POME) as many as 2500 l/ton of CPO. POME contains Chemical Oxygen Demand (COD) average of 21,280 mg/l, Biochemical Oxygen Demand (BOD) average of 34,720 mg/l, fatty oils average of 3,075 mg/l and the average pH of 4. Wastewater treatment systems in the palm oil industry is the combination of physical processes such as sedimentation and biological processes, either anaerobic or aerobic. The weaknesses of conventional processing systems is a long processing time (10-90 days) and require extensive land area (± 6 times the total area of the factory). This study aims to provide an alternative method for POME treatment with plasma system through Dielectric Barrier Discharge (DBD). The results showed removal efficiency for COD, BOD and fatty are 53%, 55 % and 40 % with the processing time of 4 hours, respectively. Beside, consumed energy was 7.2 kWh/l for voltage application of 19 kV.

Abstrak
Proses pengolahan kelapa sawit menjadi minyak sawit mentah atau Crude Palm Oil (CPO) menghasilkan limbah cair sawit sebanyak 2500 l/ton CPO. Limbah cair kelapa sawit ini mengandung Chemical Oxygen Demand (COD) rata-rata sebesar 21.280 mg/l, Biochemical Oxygen Demand (BOD) rata-rata sebesar 34.720 mg/l, minyak lemak rata-rata sebesar 3.075 mg/l dan pH rata-rata sebesar 4. Sistem pengolahan limbah cair kelapa sawit di industri adalah dengan kombinasi proses fisik seperti sedimentasi dan proses biologi, baik secara anaerob atau aerob. Kelemahan dari sistem pengolahan konvensional adalah waktu pengolahan yang lama (10-90 hari) dan membutuhkan lahan yang sangat luas (± 6 kali dari luas areal pabrik). Penelitian ini bertujuan untuk memberikan alternatif pengolahan limbah cair kelapa sawit dengan sistem plasma melalui metoda Dielectric Barrier Discharge (DBD). Hasil penelitian menunjukan efisiensi penghilangan COD sebesar 53%, BOD sebesar 55% dan minyak lemak 40% dengan waktu pengolahan 4 (empat) jam. Konsumsi energi yang dibutuhkan 7,2 kWh/l untuk tegangan pembangkitan 19 kV.
