Abstract

Escherichia coli bacteria are bacteria used as indicators of contamination. Bacteriological water testing can use a Membrane Filtration (MF) and a Multiple Tube-Fermentation (MTF). This study aims to compare the membrane filtration and Multiple Tube-Fermentation methods on the presence of Escherichia coli in clean water. The two methods are compared to determine the percentage difference in the results of the two tests. The research methodology uses a description of observation. 20 samples of water boreholes were used and tested for the presence of Escherichia coli. Calculation of bacterial groups uses SNI standard references regulated by the Minister of Health of the Republic of Indonesia. The results showed that the average number of Escherichia coli bacteria by the Multiple Tube-Fermentation method was less than the Membrane Filtration method. There is a difference in the percentage of the results of the two tests by 40%. Multiple Tube Fermentation is more sensitive than the Membrane Filtration method for detecting the presence of Escherichia coli in clean water.Keywords : Water, Escherichia coli, Membrane filtration, Multiple tube-fermentation

对淡水中的Escherichia大肠杆菌进行两种滤食性对照

大肠杆菌是用来作为污染指标的细菌。细菌学水测试可以使用膜过滤(MF)和多管发酵(MTF)。本研究旨在比较膜过滤法和多管发酵法对净水中大肠杆菌的影响。将这两种方法进行比较，以确定两种测试结果的百分比差异。研究方法采用观察描述法。使用了20个水井样本并检测了大肠杆菌的存在。细菌群的计算使用由印度尼西亚共和国卫生部长规定的SNI标准参考。结果表明，多管发酵法的平均大肠杆菌数量少于膜过滤法。这两种测试结果的百分比相差40%。多管发酵法检测净水中大肠杆菌的灵敏度高于膜过滤法。关键词:水，大肠杆菌，膜过滤，多管发酵
