Pekerja konstruksi memiliki risiko tinggi mengalami kelelahan kerja karena karakteristik pekerjaannya yang melibatkan aktivitas fisik berat, durasi kerja panjang, serta paparan lingkungan kerja seperti panas dan kebisingan. Kelelahan kerja dapat berdampak pada penurunan konsentrasi, ketelitian, kecepatan respons, dan human performance pekerja. Penelitian ini bertujuan untuk menganalisis faktor risiko kelelahan kerja dan dampak kelelahan kerja terhadap human performance pada pekerja konstruksi di PT X tahun 2026. Penelitian ini menggunakan desain studi cross sectional dengan jumlah responden sebanyak 113 pekerja konstruksi. Variabel yang diteliti meliputi faktor individu, faktor terkait pekerjaan, dan human performance. Pengumpulan data dilakukan menggunakan kuesioner, pengukuran beban kerja fisik melalui denyut nadi, serta pengukuran lingkungan kerja kebisingan dan suhu. Instrumen yang digunakan meliputi Fatigue Assessment Scale for Construction Workers (FASCW), NASA-TLX, dan Individual Work Performance Questionnaire (IWPQ). Analisis data yang dilakukan adalah analisis deskriptif dan analisis inferensial (analisis bivariat dan multivariat). Hasil penelitian menunjukkan bahwa faktor yang berhubungan dengan kelelahan kerja adalah waktu perjalanan, kuantitas tidur, dan beban kerja fisik dengan nilai p-value masing-masing 0,000. Berdasarkan hasil analisis multivariat, diketahui bahwa terdapat tiga variabel yang memiliki hubungan signifikan dengan kelelahan kerja, yaitu waktu perjalanan, kuantitas tidur, dan beban kerja fisik. Variabel waktu perjalanan merupakan faktor yang paling dominan berhubungan dengan kelelahan kerja dengan nilai OR = 17,057. Kelelahan kerja juga berhubungan signifikan dengan human performance dengan nilai p-value 0,023 dengan nilai OR 2,457. Hal ini menunjukkan bahwa pekerja yang tidak mengalami kelelahan kerja memiliki peluang 2,457 kali lebih besar untuk memiliki human performance tinggi dibandingkan pekerja yang mengalami kelelahan kerja.

Construction workers are at high risk of experiencing occupational fatigue due to the characteristics of their work, which involve heavy physical activity, long working hours, and exposure to work environment factors such as heat and noise. Occupational fatigue may lead to decreased concentration, accuracy, response speed, and workers’ human performance. This study aimed to analyze the risk factors associated with occupational fatigue and the relationship between occupational fatigue and human performance among construction workers at PT X in 2026. This study used a cross-sectional design involving 113 construction workers as respondents. The variables examined included individual factors, work-related factors, occupational fatigue, and human performance. Data were collected using questionnaires, physical workload measurement through pulse rate assessment, and work environment measurements, including noise and temperature. The instruments used in this study included the Fatigue Assessment Scale for Construction Workers (FASCW), NASA-TLX, and the Individual Work Performance Questionnaire (IWPQ). Data were analyzed using descriptive and inferential analyses, including bivariate and multivariate analyses. The results showed that factors associated with occupational fatigue were commuting time, sleep quantity, and physical workload, with p-values of <0.001 for each variable. Based on the multivariate analysis, these three variables had a significant relationship with occupational fatigue. Commuting time was identified as the most dominant factor associated with occupational fatigue, with an OR value of 17.057. Occupational fatigue was also significantly associated with human performance, with a p-value of 0.023 and an OR value of 2.457. This indicates that workers who did not experience occupational fatigue were 2.457 times more likely to have high human performance compared to workers who experienced occupational fatigue.
