Abstract

Staphylococcus aureus bacteria is one of the important pathogens that can cause various types of infections, ranging from mild ones such as folliculitis and impetigo to life-threatening conditions such as nosocomial pneumonia, osteomyelitis, endocarditis, sepsis, and toxic shock syndrome. Due to its ability to develop resistance to antibiotics, new alternative treatments are needed, one of which is from natural ingredients. In this study, the antibacterial activity of Scleria sumatrensis extract was tested against Staphylococcus aureus with a concentration variation of 100 - 500 µg / disc. The results showed that at a concentration of 100 ?g / disc, the extract provided antibacterial activity in the moderate category, while at a concentration of 200 to 500 ?g / disc, the activity produced was included in the strong category. These findings indicate that Scleria sumatrensis extract has the potential as a natural antibacterial agent against Staphylococcus aureus, so it is worthy of further development as an alternative therapy for infections caused by S. aureus bacteria.

Abstract

This study aimed to formulate and evaluate a lip balm preparation containing watermelon seed extract (Citrullus lanatus) as a safe and effective natural lip moisturizer, in response to the increasing demand for plant-based cosmetic products. The extract was obtained using the maceration method, and four lip balm formulations were prepared with extract concentrations of 0%, 3%, 6%, and 9%. The preparations were evaluated through physical characterization tests, irritation assessment, hedonic evaluation, and stability testing over a 10-week storage period. The results indicated that all formulations were stable, exhibited acceptable pH values and melting points, and did not cause irritation. Increasing extract concentration significantly improved spreadability and moisturizing performance, with the 9% formulation receiving the highest preference among panelists. These findings suggest that watermelon seed extract has strong potential as a natural and safe active ingredient for lip care formulations.
