Antibacterial is a compound that can inhibit the growth of bacteria that can be used for the treatment of infections in humans. One of the bacteria that can cause interference with the system is the Escherichia coli bacteria, where the Escherichia coli bacteria is widely spread around us. The spread of the Escherichia coli bacteria can occur by direct contact (shaking hands, touching). Then passed on by mouth. Leunca leaves have chemical contents including alkaloids, flavonoids, saponins, tanins. The purpose of this study was to determine whether Leunca's leaf extract (Solanum nigrum) has antibacterial effects against the inhibitory power of Escherichia coli bacteria with a concentration of 50 mg/ml, 100 mg/ml, 150 mg/ml, 200 mg/ml, 250 mg/ml. The method of this study was the sample of Leunca leaf obtained from West Lumban Rau Village, Habinsaran Subdistrict, Toba Samosir Regency. Sample preparation was done by making thick extract with the maceration method. An anti-bacterial effectiveness test is done by the disk diffusion method. The results showed Leunca's leaf extract containing alkaloid compounds, flavonoids, saponins, tannins. As well as having antibacterial effectiveness against the inhibition of Escherichia coli bacteria. Average inhibition zone area concentration of 50 mg/ml = 6.1 mm, concentration of 100 mg/ml = 7.3, concentration of 150 mg/ml = 8.8 mm, concentration of 200 mg/ml = 10.8 mm, concentration of 250 mg/ml = 12.6 mm. Conclusion: Leunca (Solanum nigrum) Leaf Extract has antibacterial effects against the inhibitory power of Escherichia coli bacteria with a strong category.

Avocado leaves (Percea americana mill) are a part of avocado plants that have benefits as traditional medicines. Avocado leaves are potentially used as anti-diarrhea based on the content of chemicals contained therein, namely saponins, alkaloids, tannins, flavanoids, polyphenols, quercetin which are used to kill pathogenic bacteria, one of which is Escherichia coli. Escherichia coli is an opportunist germ that is commonly found in the human intestine as a normal flora. The purpose of this study was to determine the inhibition of avocado leaf extract on the growth of Escherichia coli bacteria. This type of research is an Experimental laboratory. The research design used in this study was static group comparison because this study was conducted to see differences in concentrations of 10%, 15%, 25%, 50% and 75% of avocado leaf extract in inhibiting the growth of Escherichia coli bacteria by looking at the clear zone formed. The results showed that at a concentration of 25%, 50% and 75% a clear zone (inhibition zone) was formed, whereas at concentrations of 10% and 15% no clear zone (inhibition zone) was formed. From the results of this study it can be concluded that avocado leaf extract can inhibit the growth of Escherichia coli at concentrations of 25%, 50% and 75%.
