Abstract

Cileungsi River water is susceptible to biological contaminants in the form of bacteria from industrial and domestic waste, one of which is coliform bacteria. Coliform bacteria in the river can bring health risks to residents living in the vicinity, so it is necessary to add disinfectants to reduce the number of bacteria in the water. The leaves of the bride's tears plant (Antigonon leptopus) have been reported to have antibacterial properties that can be used as an alternative water disinfectant. The bioactive compounds Grosvenorine, Isoaloeresin D, and Kaempferitrinwere detected byLC-MS/MS in the methanolic extract of bride'stearsleaves and allthree compounds have been reported to have antibacterial properties from previous studies. The results of this study show that the addition of extracts can reduce the number of coliform bacteria optimally starting from 6 hours with a concentration of 10% of the total volume of water, and at 24 hours can reduce the number of bacteria up to 100%.
