| dc.description.abstract | The agricultural sector produces solid waste biomass abundantly. However, this
biomass potential has not been utilized optimally. Indonesia as the world's number one producer
of oil palm plantations produces enormous biomass potential. Oil palm empty fruit bunches
(EFB) are the largest solid waste with a fraction of around 20-23% of fresh fruit bunches.
Conventionally, it is only used as plant mulch in plantations areas. However, this biomass can
still provide added value to bioenergy products through thermochemical pyrolysis conversion.
The study was conducted with EFB raw materials that have been chopped with a size of <2mm,
heating rate of 10C/minute with temperature variations of 350°C, 400°C, 450°C, 500°C, and
550°C. The results showed that the EFB pyrolysis at low temperatures produced biochar
products, and at high temperatures, it produced maximum product in the form of bio-oil. In the
EFB pyrolysis process, biochar with an optimum yield of 36.92% was produced at 350°C, and
bio-oil with an optimum yield of 46.60% was produced at a temperature of 550°C. | en_US |
