METODE PEMURNIAN BIOGAS DARI KOTORAN SAPI DENGAN MENGGUNAKAN ADSORBEN ARANG TEMPURUNG KELAPA
Indonesia's oil reserves are only about 3.3 billion barrels
remaining. If it continues to be consumed without the
discovery of new oil reserves, it is estimated that these
oil reserves will be exhausted in the next two decades.
Biogas is an alternative energy that can be renewed as a
substitute for petroleum energy sources. This study aims
to determine the effect of flow rates on the purification
process using coconut shell charcoal adsorbents on the
chemical composition of methane (CH4) and carbon
dioxide (CO2) contained in biogas and performance on
110 cc Honda engines. Torque, effective power and fuel
consumption as the dependent variable. Flow rate
variations (1.34, 2.68, 4.02, 5.36, and 6.7 liters/minute)
and loading variations (5, 10, 15, 20 and 25 kgf) as
independent variables. Biogas produced from the biogas
purification process of cow dung with variations in the
flow rate of 6.7 liters/minute produces the highest
chemical composition when compared to the flow rate of
1.36 liters/minute, 2.68 liters/minute, 4.02 liters/minute
and 5.36 liters/minute, which is the chemical composition
of CH4 40.190% and CO2 35.371%. The application of
biogas purification on Honda 110 cc absolute revo
engine type with open throttle method at 4,500 rpm
engine speed was obtained with a flow rate of 5.80 liters
/ minute (AR10 biogas type) at a maximum load of 25 kgf
with 3375 rpm engine speed capable. produces effective
power at 4,938.17 Watts, Fuel Consumption (FC) at
1,140 liters / hour, and SFCe at 0.230 liters/hour
