Formulation and Antibacterial Activity Test of Deodorant Spray Ethanol Extract of Ambon Banana Peel (Musa Paradisiaca Var. Sapientum L.) Against the Growth of Staphylococcus Aureus Bacteria

Abstract

Ambon banana peels (Musa paradisiaca var. sapientum L.) are generally discarded as organic waste and only used as animal feed. Banana peels will benefit a lot if processed into a product. This study aims to formulate the ethanol extract of banana peel (Musa paradisiaca var. sapientum L.) into a deodorant spray preparation and test the antibacterial activity against the growth of Staphylococcus aureus bacteria using the disc paper method. In this study, 4 deodorant spray preparation formulas were made with different concentrations, namely F0 (no extract), FI (12%), FII (16%), and FIII (20%). Then the physical stability test was carried out on the deodorant spray preparation for 4 weeks including organoleptic test, pH test, clarity test, irritation test, and hedonic test from each of the 4 formulas made showing the results met the stability requirements of the deodorant spray preparation. Furthermore, the antibacterial activity test of deodorant spray preparations with concentrations of 12%, 16%, 20% and K+, K-, obtained the average value of the diameter of the inhibition zone formed, namely 11.41 mm, 16.33 mm, 18.40 mm and 11.75 mm. It can be concluded that the ethanol extract of ambon banana peel can be formulated into a deodorant spray preparation and can provide the maximum antibacterial effect at a concentration of 20% of 18.40 mm.
