ANALISIS BEBAN KERJA MENTAL DENGAN METODE NASA-TLX PADA FLIGHT OPERATIONS OFFICER DIVISI OPERASI CARTER PELITA AIR

Industri penerbangan tidak berjadwal (charter) memiliki dinamika operasional yang sangat kompleks dan bersifat ad hoc. Kondisi ini menuntut Flight Operations Officer (FOO) mengolah data penerbangan dalam durasi yang sangat terbatas. Hal tersebut memicu lonjakan beban kerja mental serta berisiko menurunkan kualitas pengambilan keputusan dan keselamatan penerbangan. Penelitian ini bertujuan untuk mengukur besaran tingkat beban kerja mental yang dialami oleh personel FOO divisi operasi carter PT Pelita Air Service serta mengidentifikasi dimensi pembentuk yang paling dominan. Penelitian ini menerapkan pendekatan kuantitatif
deskriptif. Peneliti menggunakan teknik sampel jenuh (total sampling) yang melibatkan seluruh anggota populasi sebanyak 21 personel FOO aktif. Pengumpulan data primer dilakukan melalui penyebaran instrumen National Aeronautics and Space Administration Task Load Index (NASA-TLX). Hasil penelitian menunjukkan nilai rata-rata Weighted Workload (WWL) akumulatif seluruh responden menyentuh angka 71,0, yang berada pada kategori Tinggi. Dimensi Kebutuhan Waktu (Temporal Demand) menjadi faktor paling dominan memengaruhi beban kerja mental dengan persentase kontribusi sebesar 21,71%. Faktor berikutnya secara berurutan adalah Kebutuhan Mental sebesar 20,25%, Usaha sebesar 18,12%, Performa sebesar 17,77%, Tingkat Frustrasi sebesar 11,94%, dan Kebutuhan Fisik sebesar 10,22%. Tingginya tekanan waktu berpotensi menurunkan kewaspadaan situasional FOO, sehingga manajemen perusahaan perlu mengevaluasi pengaturan jadwal giliran dinas (shift duty) dan meningkatkan otomatisasi sistem pengolahan data operasional.

The non-scheduled (charter) aviation industry features highly complex and ad hoc operational dynamics. This condition requires Flight Operations Officers (FOOs) to process flight data within a very limited time frame. This triggers a surge in mental workload and risks compromising decision-making quality and flight safety. This study aims to measure the level of mental workload experienced by FOO
personnel in the charter operations division at PT Pelita Air Service and identify the most dominant contributing dimensions. This research applies a descriptive quantitative approach. The researcher used a total sampling technique involving the entire population of 21 active FOO personnel. Primary data collection was conducted by administering the National Aeronautics and Space Administration Task Load Index (NASA-TLX) instrument. The results showed that the overall average cumulative Weighted Workload (WWL) score across all respondents reached 71.0, which falls into the High category. The Temporal Demand dimension emerged as the most dominant factor influencing mental workload, with a
contribution percentage of 21.71%. The remaining factors, in descending order, were Mental Demand at 20.25%, Effort at 18.12%, Performance at 17.77%, Frustration Level at 11.94%, and Physical Demand at 10.22%. High time pressure has the potential to reduce FOOs' situational awareness. Consequently, company management needs to evaluate shift duty roster arrangements and increase the automation of operational data processing systems.
