Refill Water Depot is currently more widely circulated and used as an alternative drinking water supply by the public. However the still unclear about the quality of the drinking water refill generated primarily of biological content. Parameters of biological contamination in drinking water caused by the Escherichia coli and coliform bacterium. This study aims to identify E. coli and coliforms in drinking water refill. Refill drinking water samples obtained from 16 drinking water refill from Jagakarsa subdsitrict. The method used is descriptive. Refill drinking water samples was taken and tested in the MPN (Most Probable Number) method and then to be tested in identification of E. coli. The results of testing the drinking water refill obtained 15 samples positive for coliform bacteria. Samples were positive for E. coli bacteria that sample B.1 and F.2.

The National Food and Drug Agency has controlled the refill drinking water in drinking water depots and also controlled food at school canteens ranging from elementary, junior high, to high school, but the National Food and Drug Agency never do food quality controlling in canteens at universities. Objectives: To identified the contamination by coliform and E. coli bacteria in drinking water at Andalas University canteen. Methods: This research was descriptive to identify coliform bacteria on  15 drinking water at the Andalas University faculty canteens.  Samples were taken directly using a sterile bottle, while data analysis using Most Probable Number  (MPN)  tables 5-1-1 and the presence of E. coli bacteria colonies from drinking water samples. Results: 9 of 15 water samples were contaminated by coliform bacteria with the highest MPN index of 240/100 ml that was found in 2 samples. From 9 samples containing coliform bacteria, all of them were found to contain E. coli bacteria. Conclusion: Most of the samples were contaminated by coliform and E. coli bacteria. Drinking water served using a kettle was more contaminated than drinking water served using gallons.Keywords: Coliform, Escherichia coli, MPN

ABSTRACT A total of 338 water samples, 261 drinking water samples and 77 bathing water samples, obtained for routine testing were analyzed in duplicate by Swedish standard methods using multiple-tube fermentation or membrane filtration and by the Colilert and/or Enterolert methods. Water samples came from a wide variety of sources in southern Sweden (Skåne). The Colilert method was found to be more sensitive than Swedish standard methods for detecting coliform bacteria and of equal sensitivity for detecting Escherichia coli when all drinking water samples were grouped together. Based on these results, Swedac, the Swedish laboratory accreditation body, approved for the first time in Sweden use of the Colilert method at this laboratory for the analysis of all water sources not falling under public water regulations (A-krav). The coliform detection study of bathing water yielded anomalous results due to confirmation difficulties. E. coli detection in bathing water was similar by both the Colilert and Swedish standard methods as was fecal streptococcus and enterococcus detection by both the Enterolert and Swedish standard methods.

Background: Based on the preliminary test using laboratory tests from three refill drinking water samples in Jemur Wonosari Village, all three were positive for Coliform. Therefore, researchers are interested in researching Analysis of the Microbiological Quality of Refilled Drinking Water at the Refill Drinking Water Depot in Jemur Wonosari Village. Objectives: Knowing the microbiological quality of refill drinking water produced at the refill drinking water depot in Jemur Wonosari Village. Research Methods: This research is a descriptive study with a cross-sectional quantitative approach using primary and secondary data sources. The population in this study were all 13 refill drinking water depots. The research takes the total population. Refillable drinking water samples were tested at the Gayung Sari Regional Health Service Laboratory. Data analysis used descriptive analysis by comparing the results of laboratory tests with Permenkes 492 of 2010. Results: The results showed that 13 samples found that 13 samples were positive for Coliform, and 13 samples were negative for Escherichia coli. According to Permenkes No. 429 of 2010, the maximum limit per 100 ml of sample is 0. So the 13 samples of refill drinking water based on microbiological parameters, namely Escherichia coli in refilled drinking water, meet the standard while the Coliform does not meet the standard. Conclusion: All refill drinking water depots in Keluraham Jemur Wonosari produce refilled drinking water whose quality does not meet the government's microbiological standards. There is a need for increased supervision and guidance at refill drinking water depots.   Keywords: Drinking Water, Microbiological Analysis, Refill Drinking Water Depot
