Abstract

Oil palm empty fruit bunch (EFB) and oil palm frond (OPF) are the overflowing lignocellulosic waste from the oil palm plantation. Converting them into biogas through anaerobic digestion is a solution for alternative energy resources. Unfortunately the digestibility of EFB and OPF are low, therefore pretreatment is an important step. The objective of this research is to study the pretreatment process and to find the best fermentation condition. Two pretreatment methods were applied in this research, mechanical and chemical pretreatment. In mechanical pretreatment, EFB was shredded and OPF were chopped. For chemical pretreatment, EFB and OPF were soaked for 24 hours at room temperature using 5% of NaOH solution. Solid state and wet fermentation conditions were applied in this research. Cow manure was used as inoculum. Under solid state fermentation, the NaOH pretreated substrates was not able to improve the biogas production due to the basic condition. The highest methane volume produced was from the untreated substrates with 40 mL volume. Under wet fermentation, the NaOH pretreated substrates was able to improve the biogas production with 685 mL of methane gas, even though the increase was not significant.
