Abstract
POME or palm oil mill effluent is currently still a waste problem that has not been utilized optimally. POME waste has the potential for renewable energy in the form of biogas, but some research results have shown that production is not optimal, so the addition of cow dung needs to be done to increase biogas production because methanogen bacteria found in cow dung help to maximize the anaerobic fermentation process and methane production. This research was conducted to determine the potential for biogas production from a mixture of POME and cow dung for 25 days by conducting a study of the biogas production process. The results of this study indicate that the biogas pressure increases with the addition of the loading rate, which is 101.102 N/m2/day to 101.107 N/m2/day with a daily biogas production of 0, 24247 liters/day with a total accumulation of biogas production for 25 days of 6.1 liters.
Highlights
Palm oil is currently the largest source of vegetable oil in the world
For every 1 tonne of Crude Palm Oil (CPO), about 5–7.5 tons of water are needed, and more than 50% of the water used in CPO production will end up as liquid waste [3]
Palm Oil Mill Effluent (POME) waste that comes out of the treatment process usually has a high temperature, which is in the range of 70800°C, with an acidity level of around 4.56 – 4.98, COD (Chemical Oxygen Demand) ranging from 57,000-60,400 mg/liter and Total Suspended Solid (TSS) 0.23 – 5.44 g/L [4]
Summary
Palm oil contributes about 27% or 46 million tons of total vegetable oil globally [1]. Indonesia is one of the largest producers and exporters of palm oil in the world. The increase in demand for Crude Palm Oil (CPO) has prompted a long-term plan for CPO production of 49 million tons/year in 2021[2]. The palm oil industry produces several types of waste in solid and liquid waste. POME waste that comes out of the treatment process usually has a high temperature, which is in the range of 70800°C, with an acidity level (pH) of around 4.56 – 4.98, COD (Chemical Oxygen Demand) ranging from 57,000-60,400 mg/liter and Total Suspended Solid (TSS) 0.23 – 5.44 g/L [4].1
