Abstract

Aloe vera (Aloe vera (L) Webb) in the world of beauty is a plant that has many properties on the skin. One of the benefits of aloe vera in the cosmetics industry is as an antibacterial. Anthraquinone contained in this plant has antibacterial activity that causes acne (Staphylococcus aureus). In addition, activated charcoal is also a trend in some beauty products that can facilitate various impurities on the facial skin. However, the use of activated charcoal with bagasse has never been done research on beauty products. Therefore, this study discusses variations in the concentration of HPMC in aloe vera gel and the concentration of activated charcoal bagasse on the antibacterial activity of Staphylococcus aureus. Making aloe vera gel is by extracting aloe vera leaves with 75% ethanol solution using maceration method. Aloe vera gel uses an empathic formula that differs in HPMC concentration. Activated charcoal added to aloe vera with three different concentrations has the aim of seeing optimal concentration. Tests in this study discuss the test of physical properties (organoleptic, pH, viscosity, and credibility) and antibacterial activity test by measuring the inhibition zone using the diffusion method.
