Water is one of the humans' basic needs that are essential in daily lives. The water use related to the production of the food processing industry must at least meet the quality standards required for drinking water. The Production process water is obtained from the artesian well that has been treated with a physical treatment process. The microbiological examination result of total Coliform is 8.6 MPN/100ml meaning that it does not meet the quality standard requirements, which is 0 MPN/100ml (The Minister of Health Regulation Number 492 of 2010, concerning Drinking Water Quality Requirements), it is necessary to treat the production process water using a Melt Blown Filter (MBF) and UV-C rays. The purpose of this study was to determine the differences in the variation of the 1, 3, and 5- microns of Melt Blown Filter cartridge 10” in reducing the amount of total Coliform, as well as the water hardness and their effect on disinfection using UV-C rays. The type of research used is experimental research with a pretest-posttest without control research design. There is a reduction in the average total Coliform after the treatment using a Melt Blown Filter, with a result of 1, 3, and 5-micron as 2.95 MPN /100ml, 3.61 MPB/100ml, and 7.31 MPN/100ml with a percentage reduction of 100%, 94.5%, and 82.4%, respectively. The average total Coliform using the Melt Blown Filter equipped with the UV-C rays treatment resulted in a reduction of 1, 3, and 5-micron as 2.95 MPN/100ml, 3.95 MPN/100ml, 8.88 MPN/100ml respectively, with a reduction percentage of 100%, for each treatment. The data analysis for total coliform using the One-Way ANOVA test resulted in a p-value of 0.001, the effective variation obtained is 1-micron MBF equipped with UV-C rays. The analysis of results pertaining to the water hardness data showed that the use of Melt Blown Filter could not reduce water hardness, but the UV-C rays could still be used accordingly. The data analysis for water hardness was performed using Kruskal-Wallis with a p-value of 0.820, meaning that there are no differences in Melt Blown Filter variation on the results of total water hardness value.
