Abstract

Limestone mining activities have an impact on respiratory disorders among workers due to the presence of dust particles smaller than 10µ. Workers experiencing respiratory issues are at risk of occupational diseases, especially as limestone mining operations continue. The presence of particulates (PM2.5 and PM10) not only causes respiratory problems but also other health issues, as a large number of particulates entering the body over a long period can increase the risk of death. The purpose of this study is to analyze the relationship between exposure to PM10 and PM2.5 dust and respiratory disorders among limestone mining workers in Kebumen Regency. This study is an analytical observational study with a cross-sectional approach, involving a population of 62 workers spread across 11 locations. The results showed a relationship between work duration (p-value = 0.024), length of exposure (p-value = 0.007), smoking habits (p-value = 0.015), use PPE (p-value = 0.003), and disease history (p-value = 0.000) with respiratory disorders. Meanwhile, age, PM2.5, and PM10 levels did not show a relationship with respiratory disorders as the p-values were > 0.05. The variables predominantly associated with respiratory symptoms were work duration (OR=5.100), length of exposure (OR=22.277), completeness of PPE (OR=17.330), and disease history (OR=7.536). Conclusion this study that PM2,5 and PM10 do not have a significant relationship with respiratory disorders among limestone mining workers in Kebumen Regency.

Abstract

The study was conducted to determine the optimal formula of transfersome propolis gel, aloe vera extract and gotu gotu leaf extract and test it against diabetic wounds in male white rats (Rattus norvegicus). The gel was created with an optimal formulation resulting from the application of a Design Expert with Cutimed as a positive control of burns on the backs of male white rats (Rattus norvegicus). Formula optimization was carried out using a Simple Lattice Design with variations of carbopol, TEA and glycerin. Activity tests of propolis transferosome gel, aloe vera extract and gotu gotu extract were conducted on 20 rats. The data results were statistically analyzed using the SPSS One Way ANOVA method. Phytochemical screening on aloe vera and gotu gotu showed the presence of flavonoid compounds, tannins and saponins. Transfersome propolis has a particle size of 88.55 nm and a zeta potential of -24.13 mV. The optimal formula produces a clear preparation in white, a distinctive odour, a stable viscosity of 19980 cps, dispersion power of 6.67 cm, adhesion of 4.07 seconds and pH of 6.45. The burn activity test had the fastest effectiveness on day 12 but did not differ significantly from the customized control.

Abstract

Red Fruit (Pandanus conoideus L.) is a typical Papuan plant that is rich in bioactive compounds such as anthocyanins, which have the potential to act as antioxidants. This research aims to analyze the chemical structure of anthocyanin compounds from red fruit ethanol extract using Fourier Transformed Infrared (FTIR) spectroscopy. FTIR is a spectroscopic tool widely used to characterize or detect functional groups and qualitatively identify compounds in samples. Anthocyanins act as antioxidants and have various biological activities such as preventing cancer, cardiovascular disease, and diabetes. Extraction was carried out using the maceration method using 70% ethanol solvent, and characterization was performed using FTIR in the wave range 4000-450 cm⁻¹. The results of the research that has been carried out show that the ethanol extract of red fruit contains secondary metabolites such as flavonoids, alkaloids, and saponins. The FTIR results of red fruit extract show the presence of functional groups characterized by the presence of the O-H, C-O-C, C-O, and C=C functional groups which are important indicators of the antioxidant properties of anthocyanins. This research confirms the potential of Red Fruit as a natural source of anthocyanins which are useful as antioxidants
