Penelitian bertujuan memperoleh gambaran dan hubungan faktor-faktor risiko individu dan pekerjaan terhadap keluhan muskuloskeletal disorder pada pekerja kantor PT. X Jakarta. Metode yang digunakan cross-sectional dengan menggunakan data sekunder hasil medical check up data dan perangkat lunak RSIGuard untuk 607 pekerja. Dari 607 pekerja terdapat 292 orang (48, 1%) mengalami keluhan musculoskeletal discomfort. Hasil uji bivariate menunjukkan hubungan signifikan (p<0,005) antara faktor individu (tinggi badan, berat badan, olahraga, jenis kelamin dan temuan masalah musculoskeletal pada MCU), dan faktor risiko pekerjaan (self-assessment risk, overall risk level, average daily mouse use, break time taken dan average strain from mouse use) dengan discomfort. Hasil uji multivariate menunjukkan jenis kelamin, temuan masalah musculoskeletal MCU, self-assessment dan overall assessment merupakan faktor-faktor yang memiliki hubungan kuat dan dapat mempengaruhi keluhan musculoskeletal discomfort. Saran-saran ditujukan untuk mencegah discomfort dan work related musculoskeletal disorder melalui prinsip-prinsip ergonomik. ......The objective of this study are to describe profile and relationship between individual and occupational risks factors with musculoskeletal discomfort in office workers of PT. X Jakarta. This is cross-sectional using secondary data of medical check up (MCU) and RSIGuard software for 607 workers. There are 272 of 607 workers (48.1%) complained musculoskeletal discomfort based on self-asessment result. Based on bivariate test results a significant (p <0.005) for individual factors (height, weight, exercise, sex and medical finding during MCU), and occupational risk factors from computer usages (self assessment risk, overall risk level, average daily mouse use, break time taken and average strain of mouse use). The final model of multivariate test results a significant correlation of gender, findings of musculoskeletal problems, self-assessment and overall assessment with musculoskeletal discomfort complaints. Suggestions addressed to reduce occupational factors to prevent discomfort and work-related musculoskeletal disorder through ergonomic principals.

Kelelahan kerja adalah masalah yang umum terjadi di bidang industri yang dapat disebabkan oleh aktivitas fisik dan mental. Kelelahan kerja merupakan salah satu masalah  dalam industri pertambangan di mana industri ini menuntut pekerja dapat bekerja dengan aman. Sekitar 32% pekerja di seluruh dunia mengalami kelelahan terkait pekerjaan,  penelitian lainnya pada perawat rumah sakit di  Indonesia menunjukkan bahwa 54,1% mengalami kelelahan kerja. Penelitian ini bertujuan untuk mengetahui hubungan antara roster kerja, shift kerja, beban kerja dengan kelelahan pada pekerja fasilitas kesehatan industri pertambangan. Survei dilakukan untuk mengukur kelelahan dan beban kerja. Peserta direkrut dengan consecutive sampling. Kuesioner National Agency and Space Administration Task Load Index (NASA-TLX) dan Swedish Occupational Fatigue Inventory (SOFI) versi Indonesia digunakan untuk menilai beban kerja dan kelelahan. Analisis data dilakukan dengan menggunakan SPSS. Variabel independen yang diteliti adalah beban kerja, roster kerja dan shift kerja dan variabel dependen yang diuji adalah kelelahan. Penelitian ini melibatkan 97 responden dari fasilitas kesehatan di industri pertambangan. Analisis multivariat  regresi logistik untuk menilai faktor-faktor yang berhubungan terutama beban kerja dan kelelahan. Analisis multivariat menunjukkan terdapat hubungan yang bermakna antara beban kerja dengan kelelahan, di mana beban kerja tinggi dan sangat tinggi memiliki risiko 32 kali lebih besar untuk mengalami kelelahan (aOR=32,40, nilai p <0,001, CI 6,61-158,68 dan R2 0,508). ......Occupational fatigue is common in industries that are usually caused by prolonged periods of both physical and mental activity without adequate rest for recovery.  Fatigue is a significant concern in mining industry due to high-risk job in this sector that demanding workers can work safely. About 32% of workers worldwide experience work-related fatigues and another study of hospital nurses in Indonesia showed that 54.1% experienced work fatigue. This study aimed to determine the relationship between work roster, shift work, workload and fatigue in mining industry health facility workers. A survey was used to measure fatigue and workload. Participants were recruited with consecutive sampling. National Agency and Space Administration Task Load Index (NASA-TLX) and Swedish Occupational Fatigue Inventory (SOFI) Indonesian version questionnaire were applied to assess workload and fatigue, respectively. Data analysis was carried out using SPSS. The independent variables tested were workload, work roster and shift work and dependent variables tested were fatigue. The study involved 97 respondents from the healthcare facilities in mining industry. Multivariate and logistic regression analysis of the data assessed the associations factors especially workload and fatigue.   Multivariate analysis showed a significant relationship between workload and fatigue, where high and very high workloads had a 32 times greater risk of fatigue (aOR=32.40, p-value<0.001, CI 6.61-158.68 and R2 0.508).
