Sari

There are many antiseptic soaps on the market both from industrial and household production. Antiseptic soap can be used to reduce bacterial contamination in parts of the body due to waterborne or dirty hands such as Escherichia coli and Salmonella sp. Antiseptic soap is different from ordinary soap, because it has ingredients that can function as antimicrobials. So it is necessary to do an antimicrobial test against antiseptic soap. The soap tested in this study is antiseptic transparent soap for household production. The use of Escherichia coli and Salmonella sp. test bacteria is because these two types of bacteria are bacteria that often cause disease. This research was carried out from 6 to 11 October 2018. Testing was carried out by diffusion method. The test sample was antiseptic transparent soap and sterile distilled water (negative control). Results analysis showed the use of antiseptic transparent 1% soap suspension against Escherichia coli and Salmonella sp. each has an average inhibition zone diameter of 7 mm and 5.75 mm while in the negative control using sterile aquades there is no inhibitory zone. Based on the classification of bacterial growth inhibition response according to Greenwood which was cited by Fitri (2010), the use of antiseptic transparent 1% soap suspension against Escherichia coli and Salmonella sp. classified as medium category.
