ANALISIS KUANTITATIF BAKTERI ESCHERICHIA COLI PADA AIR MINUM ISI ULANGDI WILAYAH SUNGAI BESAR KOTA BANJARBARU
Abstract
Water is the most vital necessity for human life and other living creatures. Provision of safe drinking water must be pursued because of the possible contamination of microorganisms in drinking water, such as Escehrichia coli bacteria contamination that can cause diarrhea. According to the requirements of Regulation of the Minister of Health of the Republic of Indonesia No. 492 / Menkes / Per / IV / 2010 on the drinking water quality requirements that the maximum levels of Escherichia coli in drinking water refills are allowed in per 100 ml sample is 0/100 ml. The purpose of this study was to determine the presence or absence of bacteria Escherichia coli in drinking water refills and how many levels of MPN / 100 ml as well as to determine whether the refill drinking water sold in the region of the Great River Banjarbaru meet the requirements of Regulation of the Minister of Health of the Republic of Indonesia Number 492 / Menkes / Per / IV / 2010. This research uses descriptive research. This study was conducted in December 2015. The data collection technique uses accidental sampling and in this study using the method of Most Probable Number MPN / 100 ml. The results of this study are as much as 2 samples (15.38%) tested positive for the bacteria Escherichia coli and 11 samples (65.78%) negative bacteria Escherichia coli. Number MPN / 100 ml of the bacterium Escherichia coli is the highest is 15 MPN / 100 ml and the number of MPN / 100 ml of the bacterium Escherichia coli lowest is 4 MPN / 100 ml. In the calculation of the number of colonies with tables MPN / 100 ml of 2 positive samples exceeded the limit entirely the requirements of Regulation of the Minister of Health of the Republic of Indonesia No. 492 / Menkes / Per / IV / 2010 with the maximum allowable levels of 0/100 ml.
