Abstract
Aspergillus brunneoviolaceus partial is an endophytic fungi isolated from the roots of the plant Syzygium aqueum. The potential of this endophytic fungi is not only beneficial for the host plant, but also beneficial for humans as herbal medicines, one of which is overcoming bacterial resistance to antibiotics. This study aims to determine the effect of the ethyl acetate extract of the fungi Aspergillus brunneoviolaceus partial on Escherichia coli bacteria and the concentration that can provide antibacterial activity, as well as the research contribution that can be given in learning biology. The type of research used is experimental quantitative research with Completely Randomized Design (CRD). The data obtained were analyzed using the Anova test and Duncan's Real Distance Difference test. There were 5 treatments used, namely positive control (ciprofloxacin), concentrations of 1000 ppm, 500 ppm, 250 ppm, and 125 ppm with 3 repetitions. The result of this research is the formation of an inhibition zone around the paper disc in each treatment. The average diameter of the inhibition zone at a concentration of 1000 ppm was 14.94 mm, a concentration of 500 ppm was 5.89 mm, a concentration of 250 ppm was 11.9 mm and a concentration of 125 ppm was 6.26 mm. The results of the Anova test showed a significant value of 0.04 and Duncan's test showed that the positive control was significantly different from all concentrations except the concentration of 1000 ppm, and the research contribution was in the form of booklets as learning media. This shows that the ethyl acetate extract of the fungi Aspergillus brunneoviolaceus partial has an effect on Escherichia coli bacteria and at a concentration of 125 ppm it has shown antibacterial activity.
