The objective of this study was to evaluate the effect of different initial carbon to nitrogen (C/N) ratios on the organic matter degradation during active co-composting of oil palm empty fruit bunch (OPEFB) and palm oil mill effluent (POME) anaerobic sludge. The initial C/N ratio was varied from 25:1, 35:1 and 45:1. Co-composting was conducted by periodic addition of sludge to maintain the moisture content and enrich the compost product. The organic matter (OM), carbon to nitrogen profile and compost maturity index were analysed. The results showed that the initial C/N ratio of 35:1 was the best initial C/N ratio. In addition, the C/N ratio of 35:1 gave the best OM degradation. The appropriate amount of initial C/N ratio coupled with the correct composting process parameters such as daily mixing, suitable pH and moisture content improved the organic matter degradation. It reduced the composting time from 40-60 days to 30 days.

This study aimed was to isolate non-symbiotic N-fixation bacteria from oil palm plantations fertilized with empty fruit bunch (EFB) and palm oil mill effluent (POME) and to analyze their potency. The soil samples were taken by purposive sampling method from 4 different treatments are mixed application (EFB + POME), EFB application, POME application and without application (C), and each location was taken 3 times. Isolation of non-symbiotic N-fixation bacteria was perfomed by using NFb and Ashby's media. The parameters observed were bacterial cells number, number of isolates and their potency. The cells number of non-symbiotic N fixation bacteria at the application sites Mixed> POME application> EFB application> C. A total of 18 isolates were isolated and potentially as a nitrogen fixing bacteria characterized by the ability of isolates to change the color of the NFb medium from green to blue and form pellicle. The highest potential isolates are NFBC232, NFBK21, and NFBC33.
