Abstract The drinking water that does not fulfill the bacteriological standard will give an impact on human health. If it is drunk by the people, the alive pathogenic bacteria will enter into the human intestine again and it will cause a disease. Water has a function as the water-washed disease. Ipomoea carnea used as an antibacterial alternative in drinking water containing active ingredients such as alkaloids and flavonoids. Aim this research was conducted for proving that Ipomoea carnea, as an antibacterial agent, can decrease the bacteriological content in drinking water, using an extract of Ipomoea carnea and drinking water source processed by the community. The data was collected from the production of Ipomoea carnea extract made from all parts of it i.e. roots, stems, leaves, flowers, seeds, and the mixture of all of those parts by using the maceration with 96% ethanol, from testing the quality and the quantity of active ingredients such as alkaloids and flavonoids in Ipomoea carnea, and from testing the quality of drinking water source using Coliform Most Probable Number (MPN). The analysis was done using one-way ANOVA. All parts of Ipomoea carnea could decrease the number of bacteria in 100 ml drinking water sample with various doses of Ipomoea carnea extract (0.2 gram, 0.3 gram, and 0.4 gram). The extract of Ipomoea carnea leaves could decrease the highest number of bacteria with a dosage of 0.2 gram by 79.67%. According to WHO and Regulation of MoH-RI No.492/Menkes/Per/IV/2010 on the Drinking Water Quality Requirements, the number of bacteria should be zero. The decrease in extract dosage is required for fulfilling the drinking water quality standards. The decrease in the number of germs or bacteriological in drinking water source using Ipomoea carnea can increase the quality of drinking water.
