Abstract

Aging is an unavoidable physiological process. The process of premature aging is prevented using natural anti-aging cosmetics derived from plants. Cosmetics can be used as anti-aging products. Therefore, plants can be used as substitutes for anti-aging chemicals with fewer side effects. There are many herbal plants that are empirically used by the Baduy community and have potential as anti-aging agents with tyrosinase inhibitory and antioxidant activities. Evidence of anti-aging activity can be obtained by testing the effects of each herbal plant, which has been conducted by several researchers previously. The purpose of this article is to provide information on which plants have the potential as anti-aging agents for cosmetic raw materials thru a literature review of journals in electronic databases. The results obtained from several plants such as Carica papaya L., Kaempferia galanga, Psidium guajava, Zingiber officinale var. Rubrum, Piper bettle, Caesalpinia sappan L, and Etlingera elatior (Jack) R.M. Sm have tyrosinase inhibitory activity. Orthosiphon stamineus B., Coleus scutellarioides (L.) Benth, and Imperata cylindrica (L) Beauv., the cogongrass plant, use an antioxidant approach as anti-aging. In conclusion, all herbal plants from the Baduy tribe have the potential as raw materials for anti-aging cosmetics

Abstract

Diabetes mellitus (DM) is a chronic metabolic disease characterized by hyperglycemia due to impaired insulin production or utilization. The increasing prevalence of diabetes, especially type 2, is a global concern due to the risk of complications it poses. One approach in treating type 2 diabetes is to inhibit the α-glucosidase enzyme to slow down glucose absorption. This research aims to identify the potential of patikala leaf extract as an α-glucosidase enzyme inhibitor. Using an experimental method with patikala leaf samples collected from Mariri Hamlet, Banyuurip Village, Bone-bone District, North Luwu Regency. Extraction was performed using the maceration method with variations in solvents: 70% ethanol, ethyl acetate, and n-hexane. The α-glucosidase enzyme inhibition activity was measured using a microplate reader and analyzed to determine the IC50 value. From the percentage inhibition data, the IC50 values obtained for 30% ethanol extract of patikala leaves were 351.95 µg/mL, for 70% ethanol extract of patikala leaves were 444.83 µg/mL, for 96% ethanol extract of patikala leaves were 362.27 µg/mL, for ethyl acetate extract of patikala leaves were 163.59 µg/mL, and for n-hexane extract of patikala leaves were 294.90 µg/mL, indicating that patikala leaf extracts with variations in solvent or extraction method exhibited very weak α-glucosidase enzyme inhibition activity. In conclusion, based on the research results obtained, the extract with variations in the solvent or extractant. Patikala leaf extract has an inhibitory activity against the α-glucosidase enzyme, which is categorized as very weak because it has an IC50 value > 100 µg/mL. In comparison, the control (acarbose) is in the weak category with an IC50 value of 50-100 µg/mL.

Abstract

Kersen leaves (Muntingia calabura L.) have long been utilized as a traditional medicinal plant used for headaches, antiseptics, antioxidants, antimicrobials, anti-inflammatories, anti-diabetics, and anti-tumors. This study aims to determine the antibacterial activity and the concentration at which kersen leaf extract can inhibit the growth of Multi Drug Resistant (MDR) Escherichia coli bacteria. The type of research conducted is a laboratory-scale experimental study. The kersen leaves were extracted using the maceration method with a 70% ethanol solvent. The antibacterial activity was tested using the agar diffusion method with sensitive and MDR Escherichia coli bacteria at varying concentrations of 1.25%, 2.5%, 5%, and 10%, conducted in three replicates and incubated for 24 hours. Subsequently, the inhibition zones were measured and the data were statistically processed. Based on the research results, at a concentration of 1.25%, an inhibition zone of 7.86 mm was obtained, at 2.5% concentration 9.65 mm, at 5% and 10% concentrations 11.93 mm and 13.98 mm on sensitive Escherichia coli bacteria, while on MDR Escherichia coli bacteria at a concentration of 1.25%, an inhibition zone of 6.51 mm was obtained, at 2.5% concentration 6.61 mm, at 5% and 10% concentrations 6.68 mm and 6.98 mm. These findings suggest that kersen leaf extract possesses moderate antibacterial activity against both sensitive and MDR E. coli, particularly at higher concentrations.

Abstract

Cosmetics are substances or preparations used on the external parts of the human body (epidermis, hair, nails, lips, and external genital organs) primarily for cleansing, perfuming, altering appearance, or improving body odor, or for protecting or maintaining the body's health. Providing counselling and education on safe cosmetics to teenagers is not just about giving beauty tips; it's a crucial step in protecting their long-term health. Adolescents are in a phase of physical and hormonal transition that makes them very concerned about their appearance, but they often lack sufficient consumer literacy to distinguish between safe and harmful products. This counselling aims to educate students to be wiser in choosing safe cosmetics. The method used is direct socialization to students at SMKN 8 Makassar, providing counselling to assess the improvement in understanding after education, direct socialization, and socialization using leaflets. The results obtained show an increase in participants' knowledge of how to choose and use appropriate and safe daily cosmetics. The conclusion of this service activity is that the counselling on safe cosmetics is highly relevant and well-received by adolescents, and it is able to improve their understanding of safe cosmetics, so similar activities can be expanded to other locations.
