Pengaruh Kompetensi Verbal Bahasa Inggris dan Memori terhadap Air Traffic Control Performance Taruna di Laboratorium Aerodrome Control Tower Politeknik Penerbangan Medan

Abstract

Some research has been conducted to understand how general knowledge and short-term memory affect academic achievement. However, research that links these two predictors with air traffic control performance in a laboratory has not been found by using ATC cadets as research samples. This is an associative research with multiple correlation analysis that aims to find the correlation between English verbal competency and short-term memory toward cadets’ air traffic control performance in Aerodrome Control Tower (TWR) Laboratory. The research instruments used are oral proficiency interview, Intelligence Structure Test (IST), and air traffic control simulation. Data obtained, then, are analyzed by using the product-moment method of correlation. The results show that there is a positive correlation among the three variables with the level of closeness that falls in the high category that can be seen from the correlation coefficient value of 0.787. English verbal competency and short-term memory contribute 61.9% to cadets’ air traffic control performance, while 39.1% is determined by other variables or factors.
