Abstract

Background: The rapid development of industry demands improvements in both the quality and quantity of production, which often burdens workers. Field workers, particularly at PT X, are exposed to various environmental factors that may affect pulmonary function, while heat stress significantly contributes to work fatigue. Objective: This study aimed to evaluate the relationship between forced vital capacity and heat stress with work fatigue among field workers at PT X. Methods: An analytical observational design with a cross-sectional method was employed, involving 32 field workers as research subjects. Forced vital capacity was measured using a Chestgraph Spirometer, heat stress was measured using a QuestTemp Heat Stress Monitor, and work fatigue was measured using a Reaction Timer. Data analysis was conducted using the chi-square test to determine the relationship between forced vital pulmonary capacity and heat stress with work fatigue. Results: The results showed a significant relationship between forced vital pulmonary capacity and work fatigue (p = 0.011), as well as between heat stress and work fatigue (p = 0.014). Conclusion: These findings were important as they provide an overview of workers’ physiological conditions that can influence occupational safety and productivity. It is recommended that companies routinely evaluate working conditions and workers’ health, and provide early training and heat stress management to prevent work fatigue and improve workers’ well-being.

Abstract

Computer Vision Syndrome (CVS) adalah kumpulan gejala ketidaknyamanan mata yang terjadi akibat sering atau lama menatap layar monitor. Penelitian memiliki tujuan memahami faktor yang berkaitan akan keluhan Computer Vision Syndrome. Penelitian merupakan observasional analitik, menggunakan desain cross sectional. Responden merupakan pekerja bidang KPI BBWS Bengawan Solo sebanyak 52 responden. Teknik pengambilan sampel dengan teknik total sampling. Penelitian memanfaatkan penggaris dalam ukur jarak mata responden terhadap monitor, lux meter untuk mengukur intensitas pencahayaan, dan kuesioner CVS sebagai alat ukur pengambilan data. Teknik analisis data menggunakan uji korelasi Somers’ d untuk analisis bivariat dan regresi logistik untuk analisis multivariat. Hasil korelasi Somers’d memperlihatkan 3 faktor analisis ada 2 faktor dengan keterkaitan secara signifikan akan keluhan CVS, yaitu lama istirahat mata dengan nilai p = 0,000 dan r = 0,705 serta jarak mata terhadap monitor dengan nilai p = 0,001 dan r = 0,412.

Abstract

Textile industry is a labour-intensive industry with repetitive activities and heavy physical workload, thereby likely to cause metabolic fatigue as reflected by high levels of lactic acid. This study aims to examine the independent and combined associations of Body Mass Index (BMI), blood glucose levels, and physical activity with elevated lactic acid levels among textile workers. A cross-sectional analytical study was conducted among 80 textile workers selected using at a textile company in Surakarta between January and March 2023. A series of binary logistic regression analysis were conducted, adjusting for age and sex, with statistical significance set to p < 0.05. The overall statistical significance of the model was found to be significant (p < 0.001) and the explanatory power of the model was very high (Nagelkerke R² = 55.2%). The most dominant factor associated with high levels of lactic acid was found to be the level of blood glucose above 180 mg/dL (aOR = 15.525; 95% CI: 3.003–80.263), followed by BMI over 25 kg/m² (aOR = 9.695; 95% CI: 2.155–43.617). Physical activity was found to be protective (aOR = 0.182; 95% CI: 0.037–0.891), but age and sex were not significant. These results suggest that metabolic behavioural factors are significantly associated with elevated lactic acid levels, which may indicate metabolic fatigue among textile employees. These findings highlight the importance of strengthening metabolic screening and promoting physical activity within occupational health programmes.

Abstract

Introduction: The construction sector's pivotal role in national development hinges on mitigating workplace accidents, which significantly impact productivity and project outcomes. With 32% of Indonesia's workplace accidents linked to construction incidents, maintaining high worker motivation is crucial amidst the industry's inherent complexities and uncertainties. Implementing effective safety incentive programs can bolster employee participation and compliance with safety protocols, essential for fostering a safe and productive work environment at PT X Surakarta. This study aims to investigate how safety incentive program affect safety motivation on construction worker.Methodes: This study utilizes a quantitative approach with a Pre-Experimental One-Group Pretest-Posttest design. Non-probability sampling used with a total sampling technique with 45 field workers at PT X Surakarta. Rewards on the safety incentive program are given to employees who actively contribute to meeting established criteria. Data were collected using a questionnaire designed to measure safety motivation. Data analysis involved both descriptive and inferential statistics.Result: Prior to the program, workers exhibited low motivation (mean score of 60.31), attributed to the absence of systematic rewards for safety compliance. Following program implementation, safety motivation significantly increased to a high level (mean score of 96.95), reflecting an average improvement of 36.64 points. Statistic evidence by a Simple Paired T-Test yielding a p-value < 0.001, indicating substantial improvement from pre- to post-program phases. These findings underscore the efficacy of structured safety incentive programs in enhancing construction workers' motivation towards safety practices.Conclusion: Safety incentive program showed a significant impact on safety motivation on construction worker.

Abstract

Background: Noise intensity that exceeds Threshold Limit Value (TLV) can give impacts on non-auditory on the workers in a factory, in the form of an increase in blood pressure and pulse rate. Currently, health problems due to noise have caused the company’s total loss to reach 300 billion dollars due to absenteeism rate, decreased productivity, and treatment for occupational diseases. Research in Indonesia, especially the textile industry in the city of Surakarta, shows that noise from weaving machines with an intensity above 100 dBA affects blood pressure and pulse rate. This research was conducted at textile industry in Surakarta, one of the largest textile companies in Surakarta where the company has not been able to overcome the problem of noise intensity that exceeds the TLV which has the potential to cause blood pressure and pulse disturbances, and even decreased hearing function. This study aims to determine the relationship between noise intensity with blood pressure and pulse rate in textile industry workers. Method: This research is a correlation study, which is connecting the measurement variables of noise intensity with blood pressure and pulse rate. The sample in this study were 30 female workers in the weaving division who met the inclusion and exclusion criteria. The instruments used in measuring noise were sound level meters and sphygmomanometers. Data analysis used the Pearson correlation test to determine the relationship between noise intensity with blood pressure and pulse rate disturbances.Result: The study showed significant correlation between noise intensity and pulse rate with a p value of 0.029, but noise intensity with blood pressure disturbances does not correlate, with a p value of 0.443.Conclusion: There is a relationship between noise intensity and pulse rate of the workers in a factory.
