Peel-off Mask Formulation from Stem of Sempeng (Nepenthes gracilis) as Anti Acne Against Propionibacterium acnes Bacteria

Introduction: Stem of Sempeng (Nepenthes gracilis), which contain saponin and tannin has been known had antibacterial activity against Propionibacterium acnes that usually improve severe of acne. Acne is a skin disease characterized by chronic inflammation in the polisebasca that often occurs in adolescence. Aims and Objective: The aims of this research are to develop and test a peel-off mask prepared from stem of Sempeng extracts, which has antibacterial activity against Propionibacterium acnes. Materials and Methods: Stem of Sempeng was extracted with soxhletation method by ethanol 96%. The extract was formulated into peel-off mask with different extract concentration (0, 1, 5, 10, 15) %. Then the inhibition test of the extract and peel-off mask was measured against bacteria Propionibacterium acnes. The data analysis technique used in this study was to measure the zone diameter on a petri dish using a caliper with a millimeter (mm) unit and presented in tables and photos, the results of the inhibition zone measurement were compared with the classification of the response of the extract barrier to the growth of Clinical and Laboratory Standards Institute (CSLI) standard bacteria. Results: The result showed that the inhibition zone of the peel off mask preparation of sempeng stem extract in F1 and F2 formulations with extract concentrations of 1% and 5% are categorized as resistant, which means that the Propionibacterium acnes bacteria has a low level of sensitivity so that a large inhibition zone is not formed. Whereas in the F3 formulation with a concentration of 10% is categorized as an intermediate, which means in this concentration, the mask can inhibit the growth of the inhibition zone Propionibacterium acnes bacteria which is formed quite well, but in this category it will require repeated use or with high doses of use. Then in the F4 formulation with a concentration of 15%, it is categorized as susceptible, which means the mask have a good inhibitory resistance zone, this shows that the increase in high concentration, the greater the inhibition zone as well. Conclusion: The peel off mask from ethanol extract of Sempeng stem is able to inhibit the growth of Propionibacterium acnes bacteria. The peel mask preparation with concentration 1%, 5%, 10% and 15% forms a clear zone around the disc which means that this peel off mask formulation has activity to inhibits Propionibacterium acnes bacteria and is included in the category of susceptible interpretation according to the CLSI standard.
