Biogas production from oil palm Mesocarp fibre with alkaline pre-treatment

---

Oil Palm production is very important to the economy of Indonesia, it was produced over 34.5 million tons in 2016. High productions of Oil Palm lead to high production of waste. Oil Palm Mesocarp Fibre (MF) is one of the most wastes that produced by the Oil Palm plant, and created a major disposal problem. Converting it into biogas through anaerobic digestion process is a solution for more valuable wastes. Unfortunately, the digestibility of mesocarp fibre is low. Hence, pre-treatment is needed. The objective of this research is to find the most optimum alkaline pretreatment for the mesocarp fibre. Two pre-treatment methods were applied in this research, which is mechanical and alkaline pre-treatment. In mechanical pretreatment, mesocarp fibre was pulverized with a disk mill. For chemical pretreatment, mesocarp fibre was soaked for 2 hours, 3 hours and 4 hours at 70o C using 6% of NaOH solution. Biogas sludge was used as the inoculum. The highest CH4 produced achieved from the mesocarp fibre with 4 hours of retention time and produced 4170 mL of methane gas. The raw mesocarp fibre acts as a reference produced 337 mL of methane gas. This experiment shows that alkaline pre-treatment can increase the CH4 production.
