    Abstract
    Characteristics of palm oil mill liquid waste of effluent RANUT (Reactor Anaerobic Fixed bed) was not meet yet the basic quality requirement of liquid waste for TSS (Total Suspended Solid) and COD (Chemical Oxygen Demand).. Therefore it requires further treatment to reduce pollutants contained, so its characteristics can meet the quality standard. In this research, electrocoagulation is used as a technique to treat the waste. The research was carried out by using the factorial design with three factors, those are kind of electrode material, voltage, and distance of electrode. Type of electrode material used is aluminium, zink and iron. Voltage variation are 11, 12 and 13 Volt, while the distances of electrode used are 1.0; 1.5 and 2.0 cm. While the constant variabels are pH 6.5, and retention time 3 hours. The treatment was operated in batch reactor with volume of 2000 mL. The Responses would be observed are changes of pH, removal percentage of turbidity, color, TSS, and COD. Analysis of pH was carried out by using a pH meter SensIon156, COD by HACH Method 8000, TSS was according to SNI 06-2413-1991, the color by method 8025, and turbidity by Nephelometric method. Research results found that electrocoagulation could increase the price of waste pH. Best pH is 7-8 which was obtained by using aluminium electrode. Highest percentage of pollutant removal is obtained by using aluminium electrode at voltage 12 Volt and distance of electrode 1.5 cm, with their exclusion percentage of turbidity is 98.40%, color is 97.55%, TSS is 95.30% and COD is 93.46%. It was known that the value of TSS and COD were under the basic quality requirement of palm oil mill liquid waste. The results also showed that the influence of each factors and the influence of interactions between factors on the responses is significant.
     
    Karakteristik limbah cair pabrik kelapa sawit effluent RANUT (Reaktor Anaerobik Unggun Tetap) belumlah memenuhi baku mutu limbah cair yang dipersyaratkan terutama untuk parameter TSS (Total Suspended Solid) dan COD (Chemical Oxygen Demand). Oleh sebab itu diperlukan pengolahan lebih lanjut untuk menurunkan kadar bahan pencemar yang terkandung, agar karakteristiknya dapat memenuhi baku mutu. Dalam penelitian ini teknik elektrokoagulasi digunakan untuk mengolah limbah tersebut. Penelitian dilakukan dengan menggunakan rancangan percobaan faktorial dengan 3 faktor, yaitu jenis material elektroda, tegangan, dan jarak elektroda. Jenis material elektroda yang digunakan adalah aluminium, seng dan besi. Variasi tegangan yaitu 11, 12 dan 13 volt, sedangkan jarak elektroda yang digunakan adalah 1,0; 1,5 dan 2,0 cm. Adapun pH limbah dibuat tetap 6,5, dan waktu retensi 3 jam. Percobaan dilakukan dalam reaktor batch dengan volume 2000 ml. Respon yang diamati adalah perubahan pH limbah, persentasi penurunan nilai turbiditas, warna, TSS, dan COD. Analisa respon pH dilakukan dengan menggunakan pH meter Sension156, COD dengan HACH Method 8000, TSS sesuai SNI 06-2413- 1991, warna dengan Method 8025, dan turbiditas dengan metode Nephelometric. Dari hasil penelitian diketahui bahwa teknik elektrokagulasi dapat menaikkan harga pH limbah. pH terbaik didapat dengan menggunakan elektroda aluminium yaitu 7-8. Persentasi penurunan polutan tertinggi diperoleh dengan menggunakan elektroda aluminium pada tegangan 12 Volt dan jarak elektroda 1,5 cm, dengan persentasi penyisihan masing-masing yaitu turbiditas 98,40%, warna 97,55 %, TSS 95,30 % dan COD 93,46 %. Dari hasil penelitian tersebut juga diketahui bahwa kadar TSS dan COD limbah telah memenuhi baku mutu limbah cair industri minyak sawit. Hasil penelitian juga menunjukkan bahwa pengaruh utama dari tiap faktor dan pengaruh interaksi antar faktor terhadap respon adalah signifikan.
