AbstrakPenelitian ini bertujuan untuk mengetahui potensial dan waktu optimum proses elektrodesinfektan air kolam renangserta mengetahui kualitas air kolam renang berdasarkan parameter kadar hidrogen peroksida, pH dan TDS setelah proses elektrodesinfektan berdasarkan Peraturan Menteri Kesehatan RI No. 32/MENKES/PER/VI/2017.Optimasi potensial listrik menggunakan variasi 2, 4, 6, 8 dan 10 volt. Optimasi waktu yang digunakan adalah variasi 0,5; 1; 2; 3; dan 4 jam. Sampel dianalisis untuk mengetahui kadar hidrogen peroksida, pH dan TDS air kolam renang berturut-turut menggunakan metode spektrofotometri UV-Vis, pH meter dan TDS meter.Berdasarkan penelitian potensial optimumproses elektrodesinfektan sebesar 10 volt, sedangkan waktu optimum selama 4 jam dengan hidrogen peroksida yang dihasilkan sebesar 68,05 mg/L. Kualitas air kolam renang berdasarkan Peraturan Menteri Kesehatan RI No. 32/MENKES/PER/VI/2017 dikatakan baik karena memenuhi standar kualitas air kolam renang yaitu kadar hidrogrn peroksida kurang dari 0,3%, pH antara 7-7,8 serta nilai TDS air kolam renang turun dari 219 menjadi 216. Kata kunci: elektrodesinfektan, hidrogen peroksida, pH, TDS, elektroda titanium dan grafit. Abstract This study aims to determine the level of hydrogen peroxide produced from electrodesinfection process in pool water samples and determine pool water quality based on the parameters of hydrogen peroxide, pH and TDS after electrodesinfection process based on RI Minister of Health Regulation No. 32/MENKES/PER/VI/2017.Electric potential optimization uses variations of 2, 4, 6, 8 and 10 volts. The time optimization used a variation of 0.5, 1, 2, 3, and 4 hours. Determinaton of hydrogen peroxide levels, pH and TDS of pool water respectively using the spectrophotometer UV-Vis, pH meter, and TDS meter.The optimum potential and optimum time of electrodesinfection process at 10 volts and 4 hours with hydrogen peroxide up to 68,05 mg/L. Swimming pool water quality based on RI Minister of Health Regulation No. 32/MENKES/PER/VI/2017 are said to be good because the hydrogen peroxide level &lt;0,3%, the pH of pool water between 7-7.8 and the TDS are decreased from 219 to 216. Keyword: electrodesinfection, hydrogen peroxide, pH, TDS, titanium and graphite electrodes.
