The purpose of this research was to know the antibacterial effects of robusta coffee beans extract towards the bactericidal effects on Escherichia coli by dilution methods. The research type used in this research was experimental laboratory with post test only control group design. This study used 28 samples that were divided into 5 treatment groups (20%, 40%, 60%, 80%, and 100%) and 2 control groups (negative and positive control). The analysis data that used in this research was descriptive analysisThe result found that the antibacterial content in the robusta coffee beans extract at concentration 20% and 40% had no bactericidal effect on Escherichia coli.
