Abstract

Dahlia tubers are a source of carbohydrates in the form of inulin. Dried dahlia tubers are thought to contain inulin as much as 65-76% of the total carbohydrates contained. Inulin or fructoolgosaccharide is a food component that can act as a prebiotic and also as a soluble dietary fiber in humans. Inulin is thought to be able to maintain the balance of the other normal flora of the large intestine. The balance of microflora in the intestine is very necessary because these microbes can inhibit the growth of pathogenic bacteria. Escherichia coli and Salmonella typhi are among the choliform bacteria belonging to the Enterobacteriaceae family. Enterobacteriaceae are enteric bacteria or bacteria that live and can survive in the digestive tract. This study aims to compare the activity of dahlia tuber starch against Escherichia coli and Salmonella typhi bacteria by determining the activity of dahlia tuber starch. The results showed that dahlia tuber starch had antibacterial activity against Escherichia coli and Salmonella typh. Effective concentration in inhibiting Escherichia coli and Salmonella typhi bacteria at a concentration of 80% with an average LDH of 22.71 mm for Escherichia coli bacteria, while for Salmonella typhi the average LDH of 15.08 mm.

Abstract

Batak onion (Allium chinense G.Don) of the Amarylidaceae family is one of the traditional medicinal plants that has antibacterial properties, containing flavonoids, terpenoids, tannins and saponins. EEDBB extract against Propionibacterium acne (Pa), Staphylococcus aureus (Sa), Eschericia coli (Ec), Salmonella typhi (St). Batak shallot powder was extracted by maceration method using 80% ethanol as solvent. disc diffusion method of advertising concentration (EEDBB) 40%, 60%, 80% with a comparison of positive control and negative control. Measurement of antibacterial activity showed that all concentrations had antibacterial activity. The highest antibacterial activity of EEDBB at a concentration of 80% had a maximum antibacterial with an average inhibition zone of 11.5 mm for bacteria (Pa), 10 mm for bacteria (Sa), 15,5 mm for bacteria (Ec) and 16.1 mm for bacteria. bacteria (St). The lowest antibacterial activity ethanol extract at a concentration of 40% had the lowest inhibitory power with an average inhibition zone diameter of 7.8 mm for bacteria (Pa), 6.6 mm for bacteria (Sa), 12.9 mm for bacteria (Pa). . bacteria (Ec) and 13.2 mm in bacteria (St). EEDBB has the highest antibacterial activity on bacteria (St) with an average inhibition zone of 16mm. Data analysis was carried out using the One way ANOVA test, namely H0 was accepted and H1 was rejected where the value of sig < 0.05.
