Penggunaan Klorin Diffuser Mini terhadap sisa Klor pada Air Bak Bilasan Cucian Terakhir Pedagang Angkringan di Dusun Pajangan, Sumberagung, Moyudan, Sleman

Escherichia coli is one of mandatory biological parameters of environmental health standard for water media in terms of sanitation and hygiene purposes. The maximum level permitted is 0 CFU/100 ml. Based on laboratory examination, the clean water used by angkringan food stallers for food utensils at last rinse, was positively containing E.coli. Chlorine compounds can kill micro-organisms in water, because the oxygen liberated from the hypochlorous compounds oxides some important part of bacterial and make them damaged. A simple chlorination gives chlorine dose administered only in about 0,2-0,5 ppm. The application of chlorine compound in to clean water at the rinsing sink of those angkringan merchants require a chlorine diffuser. In this study, the tool was invinted in mini form with 20 holes of 1 mm diameter, and made from used felt-tip marker. This study was aimed to descriptively determine the ability and effectiveness of that mini chlorine diffuser in producing residual chlorine after being used for washing food utensils and cutleries. The water as the study object were that of the last rinsing sink of angkringan food stallers at Pajangan Hamlet of Sumberagung Village in Sleman Regency. The study was conducted in six days and examining five samples per day. The residual chlorine measurements were performed by randomly sampling one out of the five rinsing and used the appropriate test kit. Based on the examination results, the average residual chlorine obtained were: 0,22 mg/l, 0,24 mg/l, 0,24 mg/l, 0,24 mg/l, and 0,24 mg/l. Therefore, it can be concluded that the mini diffuser is able to produce residual chlorine at 0,2-0,5 ppm
