Analysis of Avtur Demand Difference at Aft Husein Sastranegara Before and After Relocation of Flights to Kertajati Airport

Abstract

The aviation industry influences a country's national and international mobility. One of the factors affecting the smooth running of this industry is the availability of jet fuel. This study therefore analyses the impact of relocating flights from Husein Sastranegara Airport to Kertajati Airport on the demand for aviation turbine fuel (ATF) at the Husein Sastranegara ATF terminal. Adopting a quantitative approach, the study compares 36 data points, comprising 18 points before and 18 points after the relocation, from May 2022 to April 2025. Descriptive statistical analysis, a paired sample t-test and simple linear regression analysis were conducted to validate the model. The results show the following: (1) A significant decrease in avtur demand, from 1,791.83 KL/month to 469.89 KL/month. (2) The t-test results show a significant difference with a very large effect size. (3) Regression analysis confirms that the decline in avtur demand is primarily due to relocation. These findings support the derived demand theory, which states that jet fuel demand depends on the intensity of flight operations.
