ABSTRACT
The use of fossil energy sources as fuel is getting bigger along with the increasing
need to make reserves of fossil energy sources dwindling. For this reason, the shift
from the use of fossil energy to new and renewable energy (EBT) is something that
must be done. Renewable energy (EBT) is energy that comes from nature and can
be renewed. Biomass is a renewable energy with abundant potential in Indonesia
which can be used as an energy source (fuel). One of the biomass with an abundant
amount is the waste generated from oil palm processing, namely oil palm empty
fruit bunches. However, OPEFB has several obstacles to use as fuel, namely it
contains high levels of potassium and low calorific value. The process of burning
EFB as the basic material for making bio-coal can cause the potassium contained
to change to form K2O compounds (potassium oxide) so that it can cause the risk
of fouling and slagging on the tubes and boiler walls. The flowing peat water
washing method is used to reduce potassium levels in empty oil palm fruit bunches
at various water flow rates (2-5 lpm). Torrefaction method is used to increase the
calorific value of empty oil palm fruit bunches at various processing temperatures
(200-300°C). The calorific value of oil palm empty fruit bunches with a torrefaction
process temperature of 300°C was obtained at 25458.91 kJ/kg. The most effective
reduction in potassium oxide (K2O) levels in oil palm empty fruit bunches with the
peat water washing process was obtained at a water flow rate of 5 lpm with a
potassium oxide content of 3.7%.
