TERHADAP Staphylococcus epidermidis}, year={2018}, url={http://librepo.stikesnas.ac.id/135/}, abstract={Pineapple (Ananas comosus L.) is one kind of fruits that interest people local or international. Pineapple has a content like flavonoid, saponin, and bromelin which can be used as antibacteria. This research aims to find out inhibitory of ethanol extract of pineapple skins (Ananas comosus L.) against Staphylococcus epidermidis and the most potential concentrations in inhibiting the growth of Staphylococcus epidermidis. The Method used is disc diffusion (Kirby & Bauer) with concentrations series 100%, 75%, 50%, dan 25% every extract. The result of inhibiting zone was obtained analyzed by descriptive qualitative method. The result of inhibiting zone is shown from each extract at 100%, 75%, 50%, and 25% concentrations of pineapple skins ethanol extract is 28,97 mm, 20,84 mm, 16,70 mm, dan 13,90 mm. Pineapple skins ethanol extract able to inhibit growing up Staphylococcus epidermidis and 100% concentrations is the most potent concentration in inhibiting growth bacterial Staphylococcus epidermidis by generating inhibiting zone amount 28,97 mm.} }
