KELIMPAHAN BAKTERI COLIFORM PADA Cerithidea cingulata SEBAGAI INDIKATOR PENCEMAR DI PERAIRAN KAMAL KABUPATENBANGKALAN

Colifrom bacteria are a group of microorganisms commonly used as indicators of water pollutants to determine whether water or waters have been contaminated by pathogenic bacteria or not. This study aims to determine the parameters of water quality in Kamal waters, to determine the presence of colifrom bacteria in Kamal waters and to determine the abundance of colifrom bacteria. The sample used in the study was Cerithidea cingulata. Sampling was carried out in 3 location points, each of which had 5 plots for taking Cerithidea cingulata. Analysis of colifrom bacteria was carried out in three stages, namely the estimation test, confirmation test and colifrom MPN calculation. Based on the National Standardization Agency and SNI 7388: 2009, the maximum limit of coliform MPN values is 1100 MPN / g, it is suspected that Kamal waters exceed the quality standard, which is 1100 MPN/g maka diduga perairan Kamal melebihi batas baku mutu yaitu
