Abstract

High content of chemical compounds of palm oil mill effluent is potential as source of organic fertilizer that beneficial for plant growth. The aim of this study was to investigate the effect of express microorganims-4 (EM-4) in reducing the chemical characteristics such as nitrogen (N), phososphorus (P), potassium (K) and chemical oxygen demand (COD) of palm oil mill effuent. The effluent was obtained from end process of crude palm oil (CPO) at oil palm plant at North Sumatera. Several concentrations of EM-4 (1, 3, 5, 7, and 9 mL) were mixed in 200 mL graduate cylider to the effluent 99, 97. 95, 93 and 91 mL respectively. All suspension were mixed homogenously and were incubated anaerobically at 29°C for 5, 10 and 15 days. All treatments were repicates 3 times. Results showed that express microorganisms-4 is effective in reducing chemical charcteristics of the palm oil miil effluent such as nitrogen, phosporus, potassium and chemical oxygen demand. In general, the highest EM-4 concentration is follwed by the lowest of the chemical characteristics.
