Abstract

It was estimated that average of 30 million tonnes of Palm Oil Mill Effluent (POME) were generated from 381 palm oil mills in Malaysia. Palm Oil Mill Effluent which is produced in a large amount by palm oil mills in Malaysia. Palm Oil Mill Effluent which is produced in a large amount by palm oil mills need attention due to its characteristics which have to be treated before released to the environment. This study aimed to optimally utilize POME as a liquid fertilizer through direct forced aeration (aerobic) method and to explore the potential of treated POME for liquid fertilizer in food crop cultivation. For this study, the POME was treated with different concentrations of biodegradable enzymes. There were four treatments which applied to treat the POME. They were 50 mL of 10% enzyme + 950 mL POME (Treatment 1, T1), 50 mL of 20% enzyme + 950 mL POME (Treatment 2, T2), 50 mL of 30% enzyme + 950 mL POME (Treatment 3, T3), 1L POME as a control. These treatments were carried under forced aeration method (aerobic). Afterwards the best quality POME after treatment is applied onto leafy mustard (Brassica juncea) to observe its effectiveness. The experiment was conducted using Complete Randomized Design. From the analysis carried out, the results showed that treatment 1 (T1) is suitable as a fertilizer due to its high nutrient content, especially Potassium (K) content where on the fifth week the value was 2666.3 mg Lˉ¹. As for other macro nutrients like Calcium (Ca) the value was 440.73 mg Lˉ¹ and Magnesium (Mg) was 591.25 mg Lˉ¹. The pH of the T1 at the fifth week was 7.82 and the initial pH was 3.99. As a conclusion, the treated POME can be used as a liquid organic fertilizer on crops due to it nutrient contents but with addition of supplements like empty fruit bunch (EFB) to enhance its quality.
