Design of Modifications to the Aircraft Cabin Baggage Measurement Goods with Fare Calculation

Abstract

Manual cabin baggage measurement in the aviation industry is currently time-consuming and prone to errors, often
confusing passengers regarding excess baggage fees. This study aims to design and modify an automated device to
measure the dimensions and weight of passengers' carry-on items, as well as calculate excess baggage fees in
accordance with Lion Air regulations for the Boeing 737 fleet. Using an experimental method, the device was
implemented with ultrasonic sensors for dimensions, load cells for weight, and a barcode scanner for passenger
identification. Measurement results are displayed on an LCD screen and can be printed as informative stickers. Key
findings indicate measurement accuracy of 98.48% for dimensions (error of 1.52%), 97.43% for weight (error of
2.56%), and 99.98% for fare calculation (error of 0.011%). The device is deemed suitable for use (validation 93.75%)
with minor revisions. This study is expected to significantly contribute to passenger baggage management and the
increased use of technology in the aviation sector.
