Abstract

ABSTRACTWork fatigue is the body's defense mechanism designed to avoid the body from overharm possibilites. Fatigue is characterized by a shift in both physical and mental state that lowers one's capacity for and endurance during work. It was established from the initial survey that 5 employees (or 50%) had moderate category fatigue and 5 employees (or 50%) had severe category fatigue. The purpose of this study was to ascertain the link between work tiredness and both physical and mental burden. A cross sectional analytic observational research design was adopted by for this study, and simple random sampling was used for the sampling method. The total sample population of this study are 87 workers. The NASA-TLX questionnaire, a reaction timer, and the 10-beat method of measuring pulse were all employed in this study. The Somers' test and the ordinal logistic regression test were employed as data analysis approaches. The findings of the bivariate analysis using the Somers'd test revealed a significant association between physical workload and work fatigue with a p-value of 0.000. According to the findings of the multivariate study, physical workload had a 7,028 times greater impact on job fatigue.

Abstract

Vocational High School is one of the vocational education that organizes education to prepare the next generation who are skilled in the industrial field. Activities at Vocational High Schools are more practical activities in workshops or laboratories. It is very important to introduce occupational safety and health to students so that they are able to recognize potential hazards in the workshop or laboratory. Based on an initial survey at the State Vocational High School 2 Surakarta, it has a machine laboratory which has lathe, milling, grinding, welding machine, and technical drawing facilities. The results of the initial survey focused on potential ergonomic hazards, because the results of observations on students who use equipment or machines in the laboratory do excessive muscle loading such as bending, twisting, neck flexion>200 and static foot positions so that potential musculoskeletal disorders can occur. So the purpose of the community service activity is to measure work posture to see the risk of musculoskeletal disorders and perform ergonomic exercises as a means of stretching muscles that experience loading. This community service activity runs with 2 methods, namely the Measurement Method and the exercise Method. The measurement method is anthropometric measurements used to determine the suitability of body posture with the dimensions of work equipment, so that these measurements can be used as a reference for the acceptance of SMKN 2 Surakarta students, especially in the aspect of height requirements. REBA measurement is a measurement of work posture that focuses on the upper body and lower body, such as the neck, shoulders, upper arms, and legs, so that we can see a picture of ergonomic risk factors in students majoring in machinery at SMKN 2 Surakarta. Nordic Body Map measurements are used to determine the level of musculoskeletal disorders. Activities in the laboratory of SMKN 2 Surakarta that have the risk of unnatural work postures have an impact on the occurrence of MSDs complaints. Exercise method, where the potential ergonomic risks are medium and high categories, it is necessary to take action to help reduce these potential hazards, one of which is by doing ergonomic gymnastics. This exercise model is made based on observations and measurements of potential ergonomic hazards, especially looking at body parts that experience unnatural work postures and static loading, so that this exercise model can be used as a way to reduce the risk of MSDs. Ergonomic gymnastics activities can be an alternative to reduce complaints of musculoskeletal disorders. The conclusion of community service activities is that activities in the lathe and technical drawing laboratories have high ergonomic risks and milling and grinding machines have moderate ergonomic risks so that ergonomic exercises can be applied before doing activities using machines or learning pauses for 5-10 minutes.

Abstract

Chronic exposure to cotton dust in the textile manufacturing industry has been a possible risk factor for pulmonary obstruction. Not many studies, however, have investigated its impact in combination with personal variables like age, gender, and length of service, particularly in developing countries. The present study investigated the impact of cotton dust exposure, age, gender, and length of service on the incidence of pulmonary obstruction among textile workers in Surakarta, Indonesia. Observational analytic study using cross-sectional design was done on 88 eligible workers. Quantitation of exposure to cotton dust was done with a High-Volume Air Sampler and lung function ascertained using spirometry. Data analysis was done through simple and multiple binary logistic regression at a significance level of 0.05. The incidence of pulmonary obstruction was 56.8%. Being exposed to cotton dust levels exceeding the threshold limit value (TLV) of 0.2 mg/m³ significantly increased the risk of pulmonary obstruction (OR: 4.18; 95% CI: 1.51–11.63; p=0.006). Employment duration was also significantly associated with pulmonary obstruction (OR: 1.21 per year; 95% CI: 1.03–1.44; p=0.023), while age and gender were not significant predictors. The accuracy of the final model was 75%, which is considered to be acceptable in occupational health studies in predictive modeling. The current research reaffirms that long-term exposure to cotton dust and extended working hours are critical risk factors for pulmonary obstruction in textile industry workers. Therefore, it is recommended to long-working-hour employees to have proper control of the exposure and continuous lung function monitoring.

Abstract

Pekerja di industri tekstil khususnya di bagian produksi, sering menghadapi tekanan kerja yang tinggi, tuntutan produksi yang ketat, dan jam kerja yang panjang, yang berisiko menimbulkan burnout. Kondisi ini dapat berdampak pada peningkatan perilaku tidak aman di lingkungan kerja, sehingga berpotensi meningkatkan risiko kecelakaan kerja. Penelitian ini bertujuan untuk mengetahui hubungan antara burnout dengan perilaku tidak aman pada pekerja bagian produksi di PT. X Surakarta. Desain penelitian yang digunakan adalah observasional kuantitatif dengan metode cross sectional. Populasi penelitian adalah seluruh pekerja PT. X Surakarta sebanyak 1.000 orang, dengan sampel sebanyak 96 pekerja yang diambil menggunakan teknik simple random sampling. Pengumpulan data dilakukan menggunakan kuesioner Maslach Burnout Inventory (MBI) untuk mengukur burnout serta kuesioner perilaku tidak aman, keduanya menggunakan skala Likert. Hasil analisis bivariat dengan Fisher’s Exact Test menunjukkan adanya hubungan yang signifikan antara burnout dan perilaku tidak aman (p = 0,026; p<0,05). Kesimpulan dari penelitian ini adalah pekerja yang mengalami burnout cenderung  melakukan perilaku tidak aman, yang diindikasikan oleh gangguan fungsi kognitif dan emosional seperti kelelahan, depersonalisasi, dan penurunan prestasi diri pekerja, dimana burnout berdampak terhadap penurunan konsentrasi dan kepatuhan terhadap prosedur keselamatan. Oleh karena itu, pendekatan psikologis penting untuk meminimalkan risiko perilaku tidak aman di lingkungan kerja industri tekstil.
