Abstract

The group of PAMSIMAS (rural clean water maintenance) in Panekan Village, Panekan Sub-District, Magetan District, uses water resource in 2 – 2.2 l/s with an easy polluted water resource preservation; The result of E Coli examination in the water resource in Panekan Village (240 E Coli germs in 100 ml/sample) is positive. This research aimed to create a chlorinator design performance using solar cell energy submersible pump to disinfect the flowing water with an appliance which can overcome the mentioned problem. This experimental research was using a method of creating chlorinator containing chlorine disinfectant and analyzing the performance the chlorinator  applying 3 various distance (0 m, 500 m, 1000 m) and chlorinator A and B. The result of the research was: the need of chlorine was 185 g/day in 1 l/s water rate of the water resource. The performance of chlorinator: solar cell, circuit control mechanical box cell, voltage stabilizer, circuit cable, 1 unit chlorine tub for each, 6 units 12 volt batteries. submersible pump 3 watt (chlorinator A) and 6 watt (chlorinator B).  The performance of chlorinator A, in a various distance of 0m, 500m and 1000m, respectively: chlorine residue: 0.58 ppm; 0.50 ppm; 0.2 ppm; E coli bacteria: 0; 0; 2 per 100 ml/sample; temperature: 25.150C; 26.140C; 25.150C; pH: 7.14; 7.09;  7.04. The performance of chlorinator B  in a various distance of 0 m, 500 m and 1000m, respectively: Chlorine residue: 0.62 ppm; 0.49 ppm; 0.18 ppm; E coli bacteria: 0; 0; 1.3 per 100 ml sample; temperature: 25.460C; 25.99 0C; 25.31 0C; pH: 7.14; 7.08; 7.1. Overall, the result of the research fulfils the requirement of Permenkes RI 492/2010. Hopefully, needs further research to improve both the power of resistance and the performance of the instrument  especially for the greater rate of water.

Abstract

Well water is one of the main resource of drinking water for the large people, especially for those who do not abonnement of PDAM (The regional corporation which suplies water need). To determine whether the well water physically polluted or not, it can be done by testing the smell, colour and taste. Whereas, to know the level of pollution both chemically and biologically, laboratory test is performed. To purify water from pathogen bacteria, the cause of waterborne deseases, it is necessary to conduct disinfecting activity to make well water safe to drink by the people. This study was experimental research. The purpose of the research was to design a chlorine injection device applied in a conventional well water, to make it safe to consume by the people. The research design was one group pre and post-test design. Then the effectiveness of the function of the device was analyzed by identifying the difference of concentration of the disinfectant (chlorine) to produce chlorine residue, smell, taste and the decrease of colifom bacteria from well water, in line with the standard of Ministry of Health No. 492 /Reg.IV/2010 about the qualification of the quality of drinking water. The result of the research on the dimension of device chlorine injection, in the form of PVC pipe 2 dm³ and 50 cm in length, completed by silicate sand (3 kg). PVC Ø ¾ , cap, doublé screw sock, disinfectant chlorine and the wieght of device is 3,6 kg. Working principle of this device was the putting of chlorine diffusely in the well wáter. The chlorine injection device type A with the chlorine concentration 10.39 g was sable to desinfect well wáter for 6 days with the average chlorine residue 0.212 ppm. While, chlorine injection device type B was able to desinfect well wáter for 16 days by using 20.97 g of chlorine. The capacity of the device was for 1000 L and the device will make the well wáter inodorous, tasteless, and free from coliform bacteria, this is in line with the standard of Ministry of Health No. 492 /Reg.IV/2010 about the qualification of the quality of drinking water. To increase the capacity of function of chlorine injection device, it is important to conduct a testing on well water in rainy season , the volume of water more than 1000 L, the content of chlor in the chlorine, the endurance of the divice, and the different level of pollution.
