Liquid Waste of Palm Oil Plantations as Liquid Fertilizer

The purpose of this study was to test the potential for sewage treatment plants Milt Palm Oil Waste (POME) as a raw material Liquid Fertilizer. Palm Oil Mill Effluent samples taken of Oil Palm Plantation PT. Minanga Ogan, South Surnatra method of analysis used for BOD Winkler method, a method Kjehdahl Nitrogen, Phosphorus appears spectrophotometermethod, K by Atomic Absorption Spectrophotometer methods and MLSS (Mixed Liquor Suspended Solid) by using the gravimetric method. The results of this study indicate an anaerobic 20,1471 BOD, 25 mg/L, N 1021.22mg/L, P 328.19mg/L, K 541.03 mg/L, and MLSS 136 mg/L BOD anaerobic ponds 2,18,421, 16 mg/L, N 876.35 mg/L, P 279.24 mg/L, K 473.59 mg/L, and MLSS 154 mg/L BOD Anaerobic an 11428,213 mg/L, N 662.61 mg/L, P 238.32 mg/L, K 348.26 mg/L, and 163 MLSS anaerobic ponds mg/L BOD 4522.81 4 mg/L, N 443.26 mg/L, P 102.22 mg/L, K 327.76 mg/L, and MLSS 198 mg/L. According to Minister of environment of the Republic of Indonesia Number 29 Year 2003 on Use of Palm Oil Technical Guidelines, the Board of Directors 3000–5000 mg/L does not pollute the environment but still have enough nutritional value for plants. It can be concluded that the anaerobic pond 4 can be directly used to, liquid fertilizer. While anaerobic pond 2 and 3 should be treated as liquid fertilizer raw materials as BOD of anaerobic Both pools are quite high.
