Abstract

Chemical dyeing and finishing processes used in the clothing and textile industries are among the main contributors that can increase the impact of climate change. Photocatalysis using nanosized titanium dioxide (TiO2) has been continuously developed as a promising technology for purifying dye wastewater into simpler and environmentally friendly components. In addition, the decoration of iron cations (Fe2+) and (Fe3+) increases the reusability of the photocatalyst due to their magnetic properties, which are easy to collect for the recycling process. Magnetic Fex+/TiO2 microfibers have been successfully prepared using a hydrothermal method using titanium dioxide in an alkaline solution. Cations were added into the solution with the different molar ratios of Ti/Fex+ to produce Fe2+/TNW and Fe3+/TNW, respectively. Photocatalysis activity test using magnetic Fex+/TNW was carried out using methylene blue in a reactor equipped with an incandescent bulb lamp representing solar light. The results showed that adding the cations resulted in a new shape of palm tree leaves, like titanate microfibers. Controlling the cation’s molar ratio produces the magnetic Fex+/TNW with a 50-150 µm length. SEM images of each material presented the uniformly elongated shape and aggregated on one side morphology. In addition, paramagnetic properties indicate that magnetic Fex+/TNW can be easily separated from the dispersion in less than 1 minute using an external magnet. A photocatalysis activity test of magnetic Fex+/TNW was performed by calculating the percent degradation of methylene blue with variations in irradiation time in visible light conditions. The result showed the effectiveness of photodegradation of methylene blue was significantly increased in materials with 3.3 molar ratios of both Ti/Fe2+ and Ti/Fe3+ with a percent degradation reaching 79% and 70%, respectively, in 5 hours. In conclusion, magnetic Fex+/TNW is introduced as an alternative dye wastewater treatment technology that has reusable properties and works well on sustainable energy sources of solar light.

Abstract

Honey is a sweet substance produced by honey bees from the nectar of flowers or other parts of plants. Honey obtained from Bone, in South Sulawesi, has been extracted and tested for antibacterial activity and toxicity. Honey was macerated with methanol to obtain a crude extract. Methanol crude extract was then partitioned successively with n-hexane and ethyl acetate to obtain ethyl acetate and methanol fraction. Antibacterial activity test was performed by agar diffusion method against Escherichia coli and Staphylococcus aureus. Methanol extract, ethyl acetate fraction, and methanol fraction showed an inhibition zone against E. coli at 10.10, 10.05, and 8.40 mm, respectively with amoxicillin as a positive control (20.05 mm). Also against S. aureus, inhibition zone was obtained at 11.90, 9.30, 8.60, and 13.70 mm for methanol extract, ethyl acetate fraction, methanol fraction, and amoxicillin, respectively. The greatest inhibition zone was obtained from methanol extract against E. coli and S. aureus, both including the strong category. The LC50 value of methanol extract and methanol fraction was 273.57 µg/ml and 765.66 µg/ml, respectively, categorized as toxic against Artemia salina, while ethyl acetate fraction was not toxic.

Abstract

Wet cupping has been shown in several studies to lower blood pressure in hypertensive patients. However, the mechanism of action remains unknown, limiting its use as a complementary non-pharmacological treatment. This study aims to examine the effect of wet cupping on systolic blood pressure, diastolic blood pressure, and nitric oxide levels in hypertensive patients. The study employed a quasi-experimental method with a pretest and post-test design, including a control group. The sample consisted of 40 individuals, they were diagnosed with primary grade I hypertension. The participants were divided into two groups (treatment and control). The intervention group received wet cupping therapy twice, at a 28-day interval, while continuing their antihypertensive medication. The control group only consumed antihypertensive medication. The study revealed a significant decrease in systolic and diastolic blood pressure but no significant increase in nitric oxide levels. After the intervention, the systolic blood pressure in the intervention group decreased by 17.69 mmHg (p=0.010), compared to a decrease of 5.87 mmHg (p=0,108) in the control group, with a difference of (p=0.010). The diastolic blood pressure in the treatment group decreased by 11.56 mmHg (p=0.000), compared to a decrease of 0.73 mmHg (p-0.570) in the control group, with a difference of (p=0.001). The nitric oxide levels in the intervention group increased by 2.5 µmol/L (p=0.530), compared to a decrease of 0.47 µmol/L (p=0.116), in the control group, with a difference of (p=0.539).  It can be concluded that wet cupping therapy reduces systolic and diastolic blood pressure but does not significantly increase nitric oxide levels in the blood of hypertensive patients.

Abstract

Tartrazine is a yellow synthetic dye that is widely used as a coloring agent in food and beverage products. However, the safety of this chemical compound is still a concern due to potential health risks such as allergic reactions, hyperactive behavior in children, increased risk of cancer and other negative impacts. This research aim to introduces a new approach to reduce the concentration of tartrazine dye using cobalt and nickel doped TiO2 nanowires. Cobalt- and nickel-doped TiO2 nanowires were synthesized by a hydrothermal method, followed by thermal treatment at 270°C, and then used in a photocatalytic reactor using UV irradiation to facilitate the reduction of tartrazine concentration. Material characterization was carried out to determine the morphology and crystallinity of the photocatalyst which is effective in reducing the absorption of tartrazine solution. The photocatalytic degradation experiment demonstrates the ability of the synthesized material as a photocatalyst, effectively reducing the absorbance of tartrazine solution, a commonly used food coloring. This finding promises significant progress in the development of sustainable food safety strategies by offering a dye degradation method.
