Utilization of Coffee Silverskin as Natural Antimicrobial in Staphylococcus aureus Bacteria

Abstrak

The research aims (1) to analyze the antimicrobial inhibition of waste of
coffee beans (coffee silverskin) from Staphylococcus aureus; (2) Studying the
characteristics of antimicrobial activity of coffee bean epidermis in Staphylococcus
aureus bacteria and (3) Determining the exact concentration of antimicrobial waste of
coffee beans from coffee beans (coffee silverskin ) on Staphylococcus aureus bacteria.
The research method used was an experimental method, which is to conduct
antimicrobial experiments on coffee silverskin. The design used is Completely
Randomized Design (CRD) 1 factor, which as a treatment is silverskin coffee extract
consisting of 4 levels of treatment namely 25%, 50%, 75%, and 100%. The parameters
observed in this study were antimicrobial inhibition, antimicrobial characteristics of
coffee silverskin, and the best antimicrobial concentration of coffee silverskin. Based
on research results that Robusta coffee bean extract can inhibit Staphylococcus aureus
bacteria. The antibacterial activity of Robusta coffee bean extract with a concentration
of 75% resulted in an inhibition zone diameter greater than other concentrations of
1.22 mm.
