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.
