Analisis Penerapan Metode Kaporitisasi Sederhana Terhadap Kualitas Bakteriologis Air PMA.

Analysis of the Implementation of Simple Chlorination Method on Bacteriological Quality in PMA Water

Miftahur Rohim, Nurjazuli, Tri Joko

ABSTRACT

Background: Water bacteriological quality is a parameter required for fresh water. The bacteriological content  is high because of the contamination from surrounding or activity of people near the area. From fact in the field, most of water bacteriological quality in Indonesia is still worse. In Flores land area, especially in Boawae the water from PMA are not treated by a good treatment water. Result of water quality monitoring program in Boawae, indicating that the MPN Coli Content is 210 Col/100 ml sample. One of the alternatives is to improve bacteriological quality is by using chlorination process of the PMA water. The aim of the study was to analyze the difference between physico-chemist parameter and bacteriological parameter in PMA water after chlorinated by using three methods (Single Tube an Layered Tube and Molasses Tube).

Methods: The research was experimental research with one group and after intervention design. Number of sample is 270: 30 samples of PMA water control, 120 samples before treatment and 120 samples after the treatment. The physico-chemist sample and bacteriological sample has examined according to examination procedure in laboratory. Data was analyzed by using method of univariate, bivariate and multivariate as Kruskal Wallis test and Cochran test.

Results: The result of the research showed that from the treatment of a single tube, layered tube and molasses tube was found that there were  differences among parameters of pH, TDS, Chlor, Fe, Mn, NO₂ , NO₃ , CaCO₃ , Coliform total, E.Coli with a 5%  p=0,0001.

Conclusion : It is concluded that based on parameter of Chlor, Coliform total and E.Coli, the better and suitable devices of water  treatment is Layered Tube
