Abstract

Total Coliform in clean water is harmful to health if it exceeds the quality standard. The total Coliform in the clean water examined was 81 APM/100 mL, which exceeds the quality standard based on the Regulation of the Minister of Health No. 32 of 2017. Ceramic membrane is a technology that can reduce Total Coliform in clean water. This technology can operate at low pressure, using natural materials such as clay and sawdust. The purpose of the study was to determine the effect of manganese greensand ceramic membranes on Total Coliform in clean water in the kitchen of PT. X. This research is a field-scale experimental study with a pretest – posttest without control design, using grab sampling technique and data analysis using the Wilcoxon test. The results of the study were the average percentage of total coliform reduction was 69.55% (composition 50:50) and 53.07% (composition 40:60). The average difference in Total Coliform is 16 CFU/100 mL (50:50 composition) and 13 CFU/100 mL (40:60 composition). The results of statistical analysis related to the effect of manganese greensand ceramic membranes on the number of Total Coliforms, namely the value of Sig. (50:50 composition) = 0.008 and (40:60 composition) = 0.017. The sig value is smaller than the value of (0.05), which means that there is an effect of manganese greensand ceramic membrane on the total coliform. Manganese greensand ceramic membrane can reduce Total Coliform and the composition variation of 50:50 is a variation that is better than the composition of 40:60.

Abstract

Water is a basic need for human life on this earth . In accordance with its use Water is very important for industrial activities , the need for clean water in the industry is divided into two, namely water for production and sanitation hygiene , for that clean water must meet good requirements in physical , chemical , and biological . Quality Chemical water in PT.Xyz for levels of Fe does not meet the requirements with levels of Fe of 1 , 56 mg / l, for it needs to do the processing of water by means of filtration . Filtration using a medium charcoal activated cob of corn . The treatment in research is to use variations of the thickness of the filter medium charcoal activated cob of corn with the thickness of the filter medium 30 cm, 40 cm and 50 cm, with the purpose to know the difference variation filter media to decrease the levels of Fe. This type of research is an experimental research design with pretest and post test without control . Mechanical taking samples that do that grab sampling . Based on the results of research filtration with a filter media charcoal activated cob corn thickness of 30 cm was able to lower the levels of Fe 89.04% , the filter medium charcoal activated cob corn thickness of 40 cm was able to lower the levels of Fe 94.53 %, and the media filter charcoal activated cob corn thickness 50 cm was able to reduce Fe content of 96.50%. In the study of this industry can use the media filter Charcoal On Cobs Corn thickness of 50 cm . because it is based on research by media filters Charcoal On Cobs Corn thickness of 50 cm can lower the levels of Fe of 0.046 mg / l and percent tase a decrease of 96.50%.
