Abstract :
Airplanes are one of the modern means of transportation at this time which
are needed to save travel time in traveling long distances. Lion Air is one of the
airline operators that uses the Boeing 737-900ER which was introduced to compete
directly with the Airbus A320-214. The performance of the Airbus A320 and Boeing
737-900ER aircraft is certainly influenced by several parameters that support the
optimal flight performance of the aircraft, including fuel consumption and costs. As
a follow-up to this phenomenon, the authors examine the comparison of the cost
and fuel consumption of the CFM56-5B4 engine on the Airbus A320-214 and the
CFM56-7B24 engine on the Boeing 737-900 ER.
The method used in this research is related to data analysis, which includes
searching for data, collecting data, organizing it, looking for patterns and then
analyzing the data using descriptive quantitative methods.
From the results of data processing, it can be concluded that the average
results of the comparison of fuel consumption and costs on the two engines are the
CFM56-5B4 engine for the Airbus A320-214 and the CFM56-7B24 engine for the
Boeing 737-900ER at the same time duration with a fuel ratio of 1 .52% or 81.25
Liters and a cost comparison of Rp.707.932. From the results of calculations and
analysis in this technical study, there are still many that are influenced by assumed
factors, so this research can still be continued and needs further development in
order to further improve the quality of writing both from a technical and other
perspective.
