The complexity of the machinery and equipment manufacturing industry involves various types of production processes, one of which is welding work. Welding is one of the most important industrial processes in joining metal or steel components. Various hazards found in the welding process such as welding metal sparks, welding sparks, welding fumes emissions, and manual handling during work pose risks to occupational safety and health for workers. This study aims to identify and assess occupational safety and health risks in the welding work process in the PT XYZ fabrication area. The hazard and risk identification stage is carried out qualitatively through observation, brainstorming activities, interviews, and reviewing company documents using the Hazard and Operability Study (HAZOP Study). After that, a semi-quantitative risk assessment analysis was carried out by assessing the multiplication of probability and severity criteria based on PT XYZ's risk assessment matrix. The results showed that there were 12 stages of the welding work process. Identified 52 hazards with 49 risks from the welding work process. The level of risk obtained includes 23 risks with very high categories, 9 risks with high categories, and 17 risks with moderate categories. Risk assessment involves risk control so that the value of the risk level can be reduced through existing controls and control recommendations provided by researchers.
Kelelahan kerja (fatigue) merupakan sebuah kondisi dimana seorang pekerja/tenaga kerja tidak bekerja secara maksimal dan mengalami penurunan produktivitas. International Labour Organization (ILO) (2016) mengatakan bahwa sebanyak 32% pekerja/tenaga kerja mengalami kasus kelelahan kerja. Selain itu, 27% pekerja/tenaga kerja mengalami kasus kelelahan kerja berat dan 18,3% pekerja/tenaga kerja mengalami kasus kelelahan kerja sedang. Kelelahan kerja juga akan dapat menyebabkan penurunan produktivitas kerja, peningkatan risiko pekerja/tenaga kerja melakukan kesalahan, dan peningkatan risiko terjadinya kecelakaan kerja. Desain penelitian pada penelitian ini adalah cross sectional. Tujuan penelitian ini adalah untuk menganalisis faktor risiko kelelahan kerja pada pekerja/tenaga kerja pengelasan di industri minyak dan gas bumi dengan pendekatan kuantitatif. Sampel pada penelitian ini berjumlah 97 pekerja/tenaga kerja welder di PT XYZ. Metode pengambilan data dengan melakukan pengisian kuesioner kepada responden dan melakukan pengukuran menggunakan alat oxymeter, lux meter, sound level meter, dan thermometer dan humidity meter. Data akan diolah secara deskriptif dan inferensial untuk melihat gambaran dan hubungan dari setiap variabel. Variabel independen pada penelitian ini adalah faktor individu (usia, masa kerja, kebiasaan merokok, dan waktu istirahat), faktor pekerja/tenaga kerjaan (beban kerja fisik, beban kerja mental, dan durasi kerja harian), dan faktor lingkungan kerja (kebisingan, pencahayaan, dan suhu). Hasil penelitian menunjukan bahwa terdapat hubungan yang signifikan antara kebiasaan merokok (OR=3.100 (1.253 – 7.672)), waktu istirahat (OR=5.913 (2.314–15.110)) , beban kerja fisik (OR=3.529 (1.509 - 8.256)), beban kerja mental (OR=2.658 (1.144–6.180)), kebisingan (OR=4.370 (1.844 – 10.354)), dan suhu (OR=4.083 (1.386-12.031)) dengan kejadian kelelahan kerja pada welder di PT. XYZ Sedangkan variabel usia, masa kerja, durasi kerja harian, dan pencahayaan tidak menunjukan adanya hubungan dengan kejadian kelelahan kerja pada welder di PT.XYZ.

Work fatigue is a condition where a worker does not work optimally and experiences decreased productivity. The International Labor Organization (ILO) (2016) said that as many as 32% of workers experience work fatigue. In addition, 27% of workers experience severe work fatigue and 18.3% of workers experience moderate work fatigue. Work fatigue can also cause decreased work productivity, increased risk of workers making mistakes, and increased risk of work accidents. The research design in this study was cross-sectional. The purpose of this study was to analyze the risk factors for work fatigue in welding workers in the oil and gas industry using a quantitative approach. The sample in this study was 97 welder workers at PT XYZ. The data collection method was by filling out questionnaires to respondents and taking measurements using an oxymeter, lux meter, sound level meter, and thermometer & humidity meter. The data will be processed descriptively and inferentially to see the picture and relationship of each variable. The independent variables in this study were individual factors (age, length of service, smoking habits, and rest time), work factors (physical workload, mental workload, and daily work duration), and work environment factors (noise, lighting, and temperature). The results showed that there was a significant relationship between smoking habits (OR=3.100 (1.253 – 7.672)), rest time (OR=5.913 (2.314–15.110)), physical workload (OR=3.529 (1.509 - 8.256)), mental workload (OR=2.658 (1.144–6.180)), noise (OR=4.370 (1.844 – 10.354)), and temperature (OR=4.083 (1.386-12.031)) with the occurrence of work fatigue in welders at PT. XYZ Meanwhile, the variables of age, length of service, daily work duration, and lighting did not show any relationship with the occurrence of work fatigue in welders at PT.XYZ.
