Abstrak: Masih minimnya penelitian tentang kelelahan akut dan kronis, terutama di industri manufaktur. Penelitian ini bertujuan untuk mempelajari faktor-faktor yang berhubungan terhadap fatigue akut dan kronis pada pekerja bagian produksi dan packaging PT X. Variabel yang diteliti yaitu faktor individu (umur, waktu tidur, commuting time), dan faktor pekerjaan yaitu (durasi kerja, shift kerja, lokasi kerja, dan waktu lembur). Skala Occupational Fatigue Exhaustion an Recovery digunakan untuk mengukur keluhan fatigue akut dan kronispada pekerja. Penelitian ini bersifat deskriptif analitik dengan menggunakan desain studi cross sectional. Hasil penelitian menunjukkan bahwa waktu tidur dan commuting time memiliki pengaruh yang signifikan terhadap fatigue akut pada pekerja, sedangkan waktu tidur dan durasi kerja memiliki pengaruh yang signifikan terhadap fatigue kronis pada pekerja.
Kata Kunci : Fatigue, Fatigue akut, Fatigue kronis, Manufaktur

There is still a lack of studies on acute and chronic fatigue, especially in the manufacturing industry.This research aims to study the factors related to acute and chronic fatigue in production and packaging workers of PT X. The studied variables in this research is comprised into individual factors such as age, time to sleep, commuting time, and job factors such as duration, shift work, location of work, and overtime. The Occupational Fatigue Exhaustion Recovery scale is used to measure acute and chronic fatigue among workers. This research is a descriptive analytic study using cross sectional study design. The results showed that the sleep time and commuting time has a significant effect on acute fatigue in workers, while the sleep time and duration of the work has a significant impact on chronic fatigue in workers.

Abstrak: Penelitian ini bertujuan menganalisis pengaruh tekanan panasterhadap fisiologis dan psikologis pekerja di PT XYZ Tahun 2016. Unitusaha utama PT XYZ yakni part otomotif dengan kegiatan press & welding.Respon fisiologis pekerja welding terhadap tekanan panas yakni peningkatansuhu, denyut nadi dan perubahan nilai berat jenis urine. Nilai Indeks tekananpanas dengan ISBB melebihi nilai ambang. Nilai Indeks Thermal Work Limitberada pada area tidak berbahaya. Analisis data dengan uji t dependent danindependent, didapatkan nilai p < 0,005. Keluhan subyektif pekerja weldingsebagai respon psikologis. Yakni adanya rasa haus, kulit berkeringat/lembab,adanya biang keringat, kejang/kram otot selaras dengan hasil pengukuranyakni adanya peningkatan denyut nadi, suhu dan berat jenis urin.

This study aimed to analyze the effect of heat stress on thephysiological and psychological workers at PT XYZ Year 2016. The businessunit of PT XYZ namely automotive parts with the activities of the press andwelding. Welding worker's physiological response to heat stress that anincrease in temperature, pulse and urine specific gravity value changes. Heatstress index value with WBGT exceeds the threshold value. Thermal WorkLimit Value Index is in the area is not dangerous. Data were analyzed bydependent and independent t test, p value < 0.005. Subjective complaints ofworkers welding as a psychological response. Namely their thirst, skin sweat/ moisture, their prickly heat, cramps / muscle cramps in tune with themeasurement results to an increase in pulse rate, temperature and specificgravity of urine.
