PENYEDIAAN AIR TAWAR DARI PENYULINGAN ENERGI SURYA MENGGUNAKAN TEKNIK REFLEKTOR CERMIN CEKUNG

Abstract

A research has been conducted to produce clean water using solar energy withconcave mirror reflector as the heater. The reflector made by 2.2 meters ofdiameter, 0.3 meters of height and 1 meter focus of the reflector. The reflectormade can be illuminated by the sunlight directly. The media of container filledwater samples to destilate that placed on focus of the reflektor. The temperature ofwater sample heated measured every one hour with time of observation from08.00 to 16.00 WIB. The observation was done if weather is good for seven days.The results of the research show that the maximum temperature of water sampleheated 100o C using the reflector. The maximum temperature of water samplewithout reflector 64oC. T he r esulut o f water volume destilated very good. Thelaboratory test of the water samples before and after distillated show that waterquality treatment increase significantly.
