In addition, the data states that as many as 32.8% or around 18,828 cases from 58,115 samples stated work fatigue. The purpose of the study was to identify the determinants of the independent variables (age, work shift, work period rest time and body mass index (BMI) with the dependent variable, namely work fatigue on workers at PT PLN. This research is an analytical study, using a quantitative approach and a cross-sectional design. using primary data. The sample in this study were all workers in the technical services section of PT. PLN (Persero) Sawangan totaling 45 workers, with a total sampling technique. Based on the results of the research on the frequency of fatigue in technical service workers of PT. PLN (Persero) Sawangan, most experiencing high work fatigue, namely as much as 82.2%. Based on the bivariate analysis, it can be seen that there is a significant relationship between age (p value = 0.037), working period (p value = 0.000), and rest time (p value = 0.000), with work fatigue and it is known that there is no significant relationship between work shifts (p value = 0.469) and body mass index (BMI) (p value = 0.156) with work fatigue. Based on the results of this study, in order to reduce work fatigue it is recommended for workers to optimize and take advantage of the rest periods that have been given. In addition, it is advisable to stretch the muscles between work.

Selain itu, data menyebutkan bahwa sebanyak 32,8% atau sekitar 18.828 kasus dari 58.115 sampel dinyatakan kelelahan kerja. Tujuan penelitian adalah mengidentifikasi determinan variabel independen (umur, shift kerja, masa kerja waktu istirahat dan indeks massa tubuh (IMT) dengan variabel dependen yaitu kelelahan kerja pada pekerja di PT PLN. Penelitian ini berupa penelitian analitik, menggunakan pendekatan kuantitatif serta desain cross sectional yang menggunakan data primer. Sampel pada penelitian ini merupakan seluruh pekerja di bagian pelayanan teknik PT. PLN (Persero) Sawangan berjumlah 45 pekerja, dengan teknik total sampling.
