This research was conducted in the laboratory of Biology University PGRI Banyuwangi to determine the effect of ganitri seeds extract (Elaeocarpus sphaericus Schum.) in inhibiting the growth of bacteria Escherichia coli and to determine the Minimum Inhibitory Concentration (MIC) of ganitri seeds extract (Elaeocarpus sphaericus Schum.). The method is using wells with 1% tetracycline positive control and negative control of sterile distilled water. Serial concentrations ganitri seed extract (Elaeocarpus sphaericus Schum.) is used by 10%, 20%, 30%, 40%, and 50%, and in the MIC test using serial concentrations of 1%, 2.5%, 5%, 7.5% and 10%. Based on the test results, the largest inhibition zone is shown by a concentration of 50% with an average diameter of 0,954 cm zone of inhibition and inhibition zone indicated smallest concentration of 10% with an average diameter of 0,215 cm inhibition zone. ANOVA test result value (F.Hit> F.Table) with F.Hit amounted to 33,512 and F.Tabel significance value of 2.85 and 0.000 (P <0.05), as the value of P <0.05 then it can be concluded that there is a concentration of ganitri seeds extract (Elaeocarpus sphaericus Schum.) on the growth of test bacteria. The results of Duncan test showed the ganitri seeds extract (Elaeocarpus sphaericus Schum.) at a concentration of 50% have significantly different inhibatory zone by treatment with 10%, 20%, 30%, 40%, positive control, and negative control. While MIC ganitri seed ethanol extract (Elaeocarpus sphaericus Schum.) Were still able to inhibit the growth of test bacteria at a concentration of 1% with an average diameter of 0.037 cm inhibition zone.

Diarrhea is caused by bacterial infections, especially Staphylococcus aureus and Escherichia coli. The breadfruit leaves (Artocarpus altilis) are known contain flavonoid compounds, alkaloids, saponins, and tannins which can be used as antibacterial. This research was conducted to determine the ethanol extract of the breadfruit leaves against Staphylococcus aureus and Escherichia coli bacteria. The manufacture of the breadfruit leaf extract was using a maceration method with 96% ethanol solvent. The result of the tube test and the TLC test was positive, the breadfruit leaf extract containing flavonoids and tannins which have potential as antibacterial. The antibacterial test was carried out using the disc diffusion method (Kirby-Bauer test) against Staphylococcus aureus and Escherichia coli bacteria incubated for 1 x 24 hours. The extract concentrations tested were 10%, 15% and 20%. The positive control was using erythromycin antibiotics and the negative control was using aquades. The identification of the chemical content of plants is done by tube test and the TLC test. The results of incubation of the breadfruit leaf extract with concentrations of 10%, 15% and 20% against Staphylococcus aureus bacteria, the average diameter of inhibitory zones respectively were 3.67, 3.50 and 2.67 mm with the positive control diameter of inhibition zone was 18.5 mm, the negative control diameter of inhibition zone was 0 mm. The results of incubation of the breadfruit leaf extract with concentrations of 10%, 15% and 20% against Escherichia coli bacteria, the average diameter of inhibitory zones respectively were 5.33, 3.17 and 3.33 mm with the positive control inhibition zone diameter of 28.5 mm and the negative control of inhibition zone diameter of 0 mm.

Mekai leaves (Pycnarrhena cauliflora Diels.) (P. cauliflora). Are known to contain flavonoid compounds, tannins and phenolics that act as antibacterial agents and are used in the treatment of eye pain. Staphylococcus aureus (S. aureus) is one of the examples of bacterial diseases of eye pain and also a major cause of many infections in communities and health facilities with cases of resistance to various antimicrobial agents. The purpose of this study was to prove the antibacterial activity of mekai leaves ethanol extract against S. aureus bacteria. This research is an experimental research. The stages of this research began by extracting mekai leaves using maceration method with 96% ethanol solvent. Antibacterial activity was tested by the disc method (Kirby-Bauer) using ethanol extract concentrations of mekai leaves (EPC) 20%, 30%, 40%, 50%, 60%, 70%, and 80%, positive control using 25 μg amoxicillin and negative control using DMSO 10%. The measurement results of inhibition zones of mekai leaf ethanol extract 20%, 30%, 40%, 50%, 60%, 70% and 80% respectively were 8.32 mm, 8.32 mm, 8.32 mm, 8.67 mm, 9.00 mm, 8.67 mm, and 8.33 mm. While the positive control measurement of 25 μg amoxicillin against S. aureus is 28.67 mm and the measurement of 10% negative DMSO control does not produce inhibitory zones, so it can be concluded that the ethanol extract of mekai leaves has antibacterial activity, but the area of ​​inhibition zone produced is smaller than amoxicillin 25 µg. The results of statistical tests using Mann Whitney between negative controls with all EPC concentrations obtained significant differences with p values ​​<0.05, it can be concluded that there is antibacterial activity produced at all EPC concentrations.

Since long ago Indonesia used nutritious plants as traditional medicines. Various types of plants in Indonesia can be used as alternative ingredients, one of which is aloe vera. Aloe vera contains saponin and anthraquinone, so aloe vera leaves function as antiseptic and antibacteria. Staphylococcus aureus is a gram-positive coccus bacteria. This bacterium is often found as a normal germ flora in humans. Staphylococcus aureus can cause infections in humans and animals. This study aims to determine the effect of ethanolic extract of Aloe vera leaves in inhibiting Staphylococcus aureus by using maceration extract method. The concentrations used were 20%, 40%, 60%, 80% and 100% with positive control (Erytromycin) and negative control (aquades). The inhibitory zone analysis is done using the table method. Test of ethanol extract of Aloe vera leaves in inhibiting Staphylococcus aureus produced inhibition zones at concentrations of 60%, 80% and 100% with average diameter of 6.94 mm, 6.22 mm and 9.5 mm. The conclusion of this research is the ethanolic extract of Aloe vera leaves can inhibit Staphylococcus aureus in high concentrations
