Abstract

Background: Toluene poses significant health hazards to humans. Occupational exposure among workers who use toluene as a solvent may lead to various adverse health effects, including dizziness, vertigo, ocular and skin irritation, respiratory disturbances, as well as disorders of the liver, kidneys, and central nervous system. This study aimed to examine the association between toluene concentration and non-carcinogenic risk characteristics with neurotoxic effects across five industrial settings in the Surabaya region. Methods: This observational study employed a cross-sectional design and was conducted in five industries in Surabaya that utilize toluene as a solvent in their production processes, located in Osowilangun, Ketintang, Jemursari, Kalijudan, and AUP Which will be implemented in 2025. The study population consisted of 90 workers exposed to toluene, of whom 77 participants were selected using an accidental sampling technique. The variables examined included toluene concentration, toluene risk quotient (RQ), and neurotoxic effects. Results: Overall, 50 workers (65%) had unsafe risk quotient (RQ) levels, and 48 workers (62.3%) experienced neurotoxic effects. Although the majority of workers (52.0%) were exposed to toluene concentrations below the threshold limit value, those exposed to concentrations above the threshold had a 1.38-fold higher risk of neurotoxic effects, and workers with unsafe RQ had a 1.4-fold increased risk compared with those with safe RQ. Statistical analysis showed no significant association between toluene concentration or RQ and neurotoxic effects (p > 0.05). Conclusion: Although not statistically significant, the study suggests that the Risk Quotient (RQ) of toluene is a key determinant of neurotoxic risk, highlighting the importance of monitoring and controlling exposure in the workplace.

Abstract

Background: Physical fatigue is a major challenge frequently encountered by perioperative nurses due to high workload, long working hours, emotional pressure, and a demanding environment requiring continuous concentration and physical endurance. The purpose of this study was to analyze the effectiveness of progressive muscle relaxation and stretching methods used by perioperative nurses on fatigue levels and injury risk. Methods: This quasi-experimental study involved 120 perioperative nurses recruited by purposive sampling and assigned to two groups: an experimental group receiving progressive muscle relaxation (PMR) and a comparison group performing stretching exercises. Physical fatigue and injury risk were measured using the IFRC questionnaire and a researcher-developed injury risk questionnaire before and after intervention. Data were analyzed using the Mann-Whitney test with a significance level of α = 0.05. Results: The primary outcomes showed a significant reduction in physical fatigue and injury risk in both groups after intervention (p < 0.05). The PMR group demonstrated a greater decrease in fatigue levels compared to the stretching group (effect size = [insert effect size]). Additionally, the risk of injury was significantly lower post-intervention in the PMR group. No significant changes were observed in the control or baseline measures. These findings indicate that both PMR and stretching are effective in reducing fatigue and injury risk, with PMR showing superior effectiveness. Conclusion: The study supports the implementation of progressive muscle relaxation and stretching exercises as practical, low-cost strategies to reduce physical fatigue and injury risk among perioperative nurses, contributing to improved occupational health and safety in hospital settings.

Abstract

Background: The Palu local shallot contains active compounds such as flavonoids and phenolics, which function as antioxidants to neutralize free radicals and possess antibacterial properties against pathogenic microbes. This study aimed to analyze and compare the phytochemical profile, total phenolic and flavonoid contents, antioxidant activity, metal-chelating capacity, and antibacterial potential of Palu local shallot extracts obtained using different solvents. Methods A maceration extraction method was performed using n-hexane, ethyl acetate, and ethanol. Each extract underwent phytochemical screening, total phenolic and flavonoid quantification, antioxidant assessment via the DPPH method, metal-chelating evaluation, and antibacterial testing. Results: The ethanol and ethyl acetate extracts contained alkaloids, flavonoids, saponins, tannins, and triterpenoids, while the n-hexane extract contained only alkaloids and triterpenoids. The ethyl acetate extract exhibited the highest phenolic content (30.35 ± 0.90 mg GAE/g), whereas the ethanol extract contained the highest flavonoid level (30.28 ± 0.57 mg QE/g). The strongest antioxidant activity was found in the ethanol extract (IC50 = 38.33 ± 1.85 μg/mL). The highest metal chelating activity is the ethanol extract (20.23 ± 0.54%). The ethyl acetate extract demonstrated the strongest antibacterial activity, yielding a 17.43 ± 0.85 mm inhibition zone. Conclusion: Ethanol is the most effective solvent for extracting antioxidant compounds from Palu local shallots, while ethyl acetate yields the strongest antibacterial activity.
