The Use Of Anti-Vibration Gloves Reduces Musculoskeletal Disorders (Msds) And Workload Of Gambelandi Artisans In Tihingan Klungkung Village, Bali

In making gamelan instruments, craftsmen are faced with the grinding process. Working with their hands exposed to vibrations for long periods of time will certainly cause musculoskeletal complaints such as stiffness and pain in the hands, tingling, loss of sensation (numbness), tremors, and can also cause several diseases such as Raynaud's Syndrome, Tenosynovitis, and Carpal Tunnel Syndrome. The purpose of this study was to determine the effect of providing anti-vibration gloves on musculoskeletal complaints, workload, and work productivity among gamelan craftsmen. This study is an experimental study with a different subject design. The population is gamelan craftsmen in Tihingan Village, Klungkung Regency. The sample was determined based on small industry groups using simple random sampling. The sample size was determined based on musculoskeletal complaint scores, resulting in a sample size of 33 people. The sample was divided into 3 groups, namely the control group, treatment group I, and treatment group II. Each group consisted of 11 gamelan craftsmen. The results obtained showed a decrease in musculoskeletal complaints of 15.34% in the control group with treatment I, and 17.69% in the control group with treatment II. There was a decrease in workload of 11.64% in the control group with treatment I and 13.80% in the control group with treatment II. There was an increase in work productivity of 4.05% in the control group with treatment I and 5.50% in the control group with treatment II. Conclusion: There was a significant decrease in musculoskeletal complaints and workload between the control group with treatment I and the control group with treatment II (p<0.05).

Sustainable Reuse of Treated Wastewater in Olive Irrigation: Impacts on Oil Bioactive Compounds, Quality, and Safety

This study evaluated the impact of irrigation with treated wastewater on the quality and safety of olive oil extracted from two cultivars (Picual and Koroneiki). Freshwater-irrigated orchards were used as control, while treated wastewater-irrigated orchards were used as treatment under a comparative experimental design. Olive fruits were analyzed for physicochemical properties, while extracted oils were evaluated for quality parameters, oxidative stability, bioactive compounds, fatty acid composition, and potential contaminants. Results showed cultivar-dependent variations in most parameters. Picual generally exhibited higher levels of bioactive compounds, including total phenolics and tocopherols, as well as greater oxidative stability compared to Koroneiki. Fatty acid composition was dominated by oleic acid in both cultivars, confirming good nutritional quality. Physicochemical indices, including free acidity, peroxide value, UV absorbance, saponification value, and refractive index, remained within international acceptable limits for extra virgin olive oil. Although treated wastewater irrigation slightly influenced some quality parameters, most differences between treatments were not statistically significant (p > 0.05). Heavy metals and pesticide residues, where detected, remained within permissible limits. Overall, the findings suggest that treated wastewater, when properly managed, does not adversely affect olive oil quality and may be considered a sustainable alternative irrigation source in olive cultivation
