[ABSTRAK
Latar belakang: Kelelahan yang dialami oleh pramugari dapat mempengaruhisebagian besar kemampuan dalam melaksanakan tugas. Tujuan penelitian iniuntuk mengidentifikasi faktor-faktor yang mempengaruhi kelelahan padapramugari sipil di Indonesia.Metode: Desain potong lintang dengan sampling purposif pada pramugari yangmelaksanakan pengujian kesehatan di Balai Kesehatan Penerbangan dan GarudaSentra Medika, tanggal 27 April?13 Mei 2015. Kelelahan diukur dengan FatigueSeverity Scale (FSS). Data dikumpulkan menggunakan kuesioner , meliputidemografi, pekerjaan, kehilangan waktu tidur , beban kerja mental dan kelelahan.Hasil: Di antara 512 pramugari yang melaksanakan pemeriksaan kesehatan, 373subyek termasuk kriteria inklusi, dengan prevalensi kelelahan 36,2%. Jumlahsektor, kehilangan waktu tidur, perubahan jadwal terbang dan kadar hemoglobinmerupakan faktor yang berhubungan dengan kelelahan. Jumlah sektor lebih darienam memiliki risiko 37% menyebabkan kelelahan [risiko relatif suaian(RRa)=1,37;p=0,095]. Kehilangan waktu tidur berisiko dua kali lebih besarmenyebabkan kelelahan (RRa=2,07;p= 0,000).Perubahan jadwal terbang dankadar hemoglobin rendah memiliki risiko 44%(RRa=1,41;p=0,011) dan33%(RRa=1,33;p=0,042) menyebabkan kelelahan.Simpulan: Jumlah sektor 7-9 dalam 24 jam terakhir, kehilangan waktu tidur,perubahan jadwal terbang dan kadar hemoglobin rendah meningkatkan risikokelelahan pada pramugari sipil di Indonesia.

ABSTRACT
Background: Fatigue among flight attendants could affect the capabilities inperforming duties. The aim of this study were to investigate factors on fatigueamong female flight attendant in Indonesia.Methods: Cross-sectional study with purposive sampling was directed to femaleflight attendant who were taking medical examination at Balai KesehatanPenerbangan and Garuda Sentra Medika, from April 27th-May 13th 2015.Fatigue was measured with Fatigue Severity Scale (FSS). Data were collected bycompleting an questionnaire on demographics, workload, sleep restriction, mentalworkload and fatigue.Results: Among 521 flight attendant were taking medical examination, 373 werechoosen as subject and the percentage of fatigue was 36.2%. Number of sector,sleep restriction, changed of duty schedule and hemoglobin level were the factorsrelated to fatigue. Subject with number of sector more than six had 37% increaserisk to have fatigue [adjusted relative risk(RRa)=1.37;p=0.095]. Subject withsleep restriction had 2-fold risk to have fatigue(RRa=2.07;p= 0.000). Subject withchanged of duty schedule and low hemoglobin levels have41%(RRa=1.41;p=0.011) and 33%(RRa=1.33;p=0.042) increase risk to havefatigueConclusions: Number of 7-9 sectors in the last 24 hours, sleep restriction,changed of duty schedule and low hemoglobin level have increased risk of fatigueamong flight attendant in Indonesia, Background: Fatigue among flight attendants could affect the capabilities inperforming duties.
