Mental Workload Assessment of Aviation Security Personnel Using NASA-TLX Method at Djalaluddin Gorontalo Airport

Abstract

Aviation safety and security are vital aspects of airport operations, with Aviation Security (AVSEC) personnel serving
as the frontline protectors. High mental workload, particularly among Junior and Senior license levels, can affect
performance and psychological stability. This study aims to assess mental workload levels based on AVSEC license
classification and propose strategies for mitigation.
A descriptive quantitative approach was applied using the NASA-TLX method, which evaluates six dimensions: Mental
Demand, Physical Demand, Temporal Demand, Performance, Effort, and Frustration. Questionnaires were distributed
to 69 AVSEC personnel at Djalaluddin Gorontalo Airport, categorized into Basic, Junior, and Senior license levels.
Raw average scores were calculated and compared across groups.
Results showed that Basic personnel scored 42.05 (moderate), while Junior and Senior scored 88 and 84 respectively
(very high). Junior personnel were most burdened by Physical Demand and Effort, while Senior personnel experienced
higher Mental and Temporal Demands. Recommended strategies include promoting qualified Basic staff, implementing
20/40-minute X-ray operator rotations, stress management training, and regular evaluations using NASA-TLX.
