PENGEMBANGAN FORMULASI MASKER EKSTRAK AIR DAUN ALPUKAT (Persea americana Mill) SEBAGAI ANTIBAKTERI Staphylococcus aureus UNTUK PENGOBATAN JERAWAT

Abstract

Skin problems are often on the spotlight, one of them is acne. Inflammation of acne can be
triggered by the bacteria Propionibacterium acne, Staphylococcus epidermidis and Staphylococcus
aureus. One of the herbs that can be used for acne treatment is the leaves of avocado (Persea
americana). This study aims to determine the potential antibacterial activity of avocado leaf
water extract on the growth of Staphylococcus aureus bacteria that causes acne and mask-making
formulation preparation. Antibacterial activity test was carried out by the diffusion method and the
observed inhibition zone that occured in a series of concentrations of avocado leaf water extract (
15%, 17.5% , 35% , 50% , 75%). Antibacterial activity test was also conducted on some avocado leaf
water extract mask formula (17.5% , 35% , 50% , 75%) was evaluated the physical properties of the
mask and irritation test was done. The results showed that the avocado leaf water extract mask formula
had antibacterial activity greater than the extract form. The physical condition evaluation and irritation
test showed that the best mask formulation was concentration of 35%.
