Abstract

The increasing demand for natural UV-protective agents has led to the exploration of plant-based bioactive compounds. Yellow root (Arcangelisia flava) extract is traditionally used in medicine and contains flavonoids, alkaloids, and terpenoids with potential photoprotective properties. This study aimed to characterize the chemical composition of A. flava extract and evaluate its UV-absorbing properties using UV-Vis and FTIR spectroscopy. The extract was obtained through maceration with ethanol, followed by spectroscopic analysis. The UV-Vis spectrum (200–400 nm) revealed multiple absorption peaks, particularly at 270 nm, 292 nm, 306 nm, 340 nm, 354 nm, 360 nm, and 396 nm, indicating the presence of UV-absorbing compounds. FTIR analysis confirmed the presence of hydroxyl (-OH), carbonyl (C=O), and aromatic (C=C) functional groups, which are characteristic of flavonoids and other bioactive compounds. These findings suggest that A. flava extract has potential as a natural UV-protective agent. Further studies on compound isolation, fractionation, and photostability assessments are required to optimize its purity and effectiveness in sunscreen formulations.

Abstract

Sunlight has been known to provide many benefits to human life. However, behind these benefits, there are some negative effects along with the destruction of the ozone layer and the environment on earth. One of them is exposure to ultraviolet (UV) rays which can cause several diseases such as skin cancer. One way to overcome this is by using sunscreen substances. In this study, dibenzalacetone immobilization on TiO2 has been carried out for anti-UV applications. Based on the test results using UV-Vis spectrometry, TiO2, and dibenzalacetone both have anti-UV properties with maximum peaks at wavelengths of 335 nm and 346 nm with absorbance values of 0.871 and 1.197. Immobilization of TiO2 with dibenzalacetone gives an absorbance with a value of 1.221 at a wavelength of 329. These results indicate that TiO2 immobilization with dibenzalacetone provides better anti-UV A properties than TiO2 because of the higher absorbance value.

Abstract

While UV light has benefits for life, excessive exposure to UV light also has negative effects on humans. Examples of the negative effects of UV exposure include cancer. Therefore, the exploration for materials that can be used as anti-UV continues to grow. One of them is extract from Leucaena leucocephala leaves. To study the potential of a compound as anti-UV, one method can use a molecular modeling approach using the semi-empirical method. Based on this, 8 flavone-derived compounds contained in L. leucocephala leaf extract were modeled with a semi-empirical approach using the PM3 method, and electronic-transition was calculated using ZINDO/S. The geometry optimization results showed that the bond length between carbon atoms in flavonoid tururnans did not change significantly with the difference in functional groups. However, there is a significant difference in the dihedral angle of the compound due to the repulsion of functional groups. The results of the electronic transition calculation showed that all flavonoid derivatives 1-8 are active in the UV A, UV B, and UV C regions. So it can be said that flavones 1-8 have potential as anti-UV. In addition, the energy level of HOMO-LUMO compounds was also calculated. Flavonoid 1 has the smallest Eg while flavonoid 8 has the largest Eg

Abstract

Clean water quality is a crucial factor in people's lives, especially for residents of Casadova Housing, Menteng, Palangka Raya, who rely on shallow wells as their main source of water. The results of the study showed that well water in this area still contains an unpleasant odor and has a low pH level (4.5), which does not meet the standards of the Minister of Health Regulation No. 32 of 2017. Therefore, this community service activity aims to socialize clean water quality standards and provide solutions for handling acidic water for local residents. The implementation method includes counseling, demonstration of simple filtration technology, and technical assistance in improving water quality. The results of the activity showed an increase in residents' understanding of clean water standards and the application of simple technologies, such as the use of lime and aeration, to reduce the acidity level of water. It is hoped that this activity can improve the quality of life of residents with access to healthier and more consumable water.

Abstract

The Community Service Program was carried out at the Harapan Farmers Group, Kereng Bangkirai Sub-district, Palangka Raya City, as an effort to provide innovative solutions to pest attack problems that often reduced fruit farm productivity. Previously, farmers had relied on manual pesticide spraying, which required considerable time, labor, and cost, and posed health risks. To address this challenge, the service team from the University of Palangka Raya developed an automated pest control system that was able to regulate pesticide spraying independently and efficiently. The activities were conducted through stages of socialization, training, and system mapping of automation in the fruit farm area, involving members of the farmers group actively. The implementation results showed an increase in participants’ understanding of the technology by 30–40 percent, improved efficiency in pesticide use by up to one-third compared to manual methods, and a reduction in working time by nearly 50 percent. This activity not only improved farmers’ skills and productivity but also served as a concrete step toward the implementation of sustainable smart farming in Palangka Raya through collaboration between the university and the community.
