Abstract
An Air Traffic Controller (ATC) operator is required to always concentrate on monitoring navigation, radiation as well as supervising and implementing aircraft guidance. Obviously such work can lead to a mental workload on the worker. Based on these problems, it is necessary to do a research on the analysis of mental workload on the operator ATC at XYZ Airport. Measurement of mental workload can be done in two ways: subjective measurement and objective measurement. Subjective measurements of the mental workload can be done with NASA-TLX method. While the objective measurement can be done by doing the measurement physiologically such as through the heart rate. The results showed that the metal workload of ATY operator of XYZ Airport was in high category and very high base on subjective measurement. Performance level is the dominant factor causing high mental work load perceived by ATC operator. While based on the objective measurement found that the mental workload of ATC operators are in the medium category.

Summary
Analisis Beban Kerja Mental pada Operator Air Traffic Controller (Atc) dengan Metode Subjektif dan Objektif. Jumlah tekanan yang berkaitan dengan waktu yang dirasakan selama elemen pekerjaan berlangsung. Hancock dan Meshkati (1989) menjelaskan langkah-langkah dalam pengukuran beban kerja mental dengan menggunakan metode NASA-TLX sebagai berikut : a. Pembobotan Bagian ini responden diminta untuk memberikan tanda silang salah satu dari dua indikator yang dirasakan lebih dominan menimbulkan beban kerja mental terhadap pekerjaan tertentu. Kuesioner NASA-TLX yang diberikan berbentuk perbandingan berpasangan yang terdiri dari 15 perbandingan berpasangan. Dari kuesioner ini dihitung jumlah tally dari setiap indikator yang dirasakan paling berpengaruh. Jumlah tally ini kemudian akan menjadi bobot untuk setiap indikator beban mental. Perbandingan berpasangan sebanyak 15 indikator dalam kuesioner NASA-TLX yang akan digunakan dalam penelitian ini dapat dilihat pada Tabel 2
