Abstract
This research was conducted using a phototransformator reactor which was used to degrade humic acid with photocatalysts of calcined CuO plates for 1 hour at 4000C. This reactor is designed in hexagonal shape made of glass with a thickness of 3 mm which has a rotation with speeds of 1000, 1500 and 2000 rpm, in this reactor filled with 200 mL of humic acid. The light source used is direct sun, the catalytic process is carried out through the process of degradation of humic acid using a reactor. The time variations used are 1, 2, 3, 4 and 5 hours. Absorption of visible light of humic acid before and after degradation was 265 nm. The results show that in direct sunlight the highest average value of %degradation is 55.66% at a velocity of 1000 rpm
