Abstract

Water is the most important substance in life after air. The ideal drinking water should be clear, colorless, tasteless, and odorless. Water can be polluted from the environment as polluted by either animal or human feces. Drinking water should not contain pathogenic germs and all creatures that endanger human health. This researcher aims to test to find out what is the content of Coliform and Colifecal in refill drinking water in Payung Sekaki District, Pekanbaru City. The benefit of this research is to provide information about the impact of drinking water that does not qualify as drinking water. The study was conducted using the MPN (Most Probable Number) method using LB (Lactosa Broth) and BGLB (Brilliant Green Lactosa Broth) media. The results showed that negative refill drinking water containing Coliform and Colifecal was in accordance with PERMENKES No. 492 / MENKES / IV / 2010, ie the bacteriological drinking water requirement was 0 per 100 ml. Coliform and Colifecal in water describe the state of the water. If the number is large, it indicates that the water is polluted by bacteria and is not suitable for use.
