One area that is developing in Indonesia is in the area of textile industry. These industries absorb a lot of labor and contribute to the country’s foreign exchange but have a negative impact in the form of wastewater produced. The wastewater produced generally contains synthetic dyes such as Reactive Red 2 (RR2). This synthetic coloring material will pollute the environment if it is not well treated first before being discharged into the environment. In this study, RR2 will be used as a pollutant model. RR2 will be treated by several methods. Pollutant concentration is an important parameter in determining the most appropriate treatment method. The purpose of this research was to study the effect of RR2 initial concentration on reducing COD and color using Fenton, Fenton/TiO 2 , Fenton/UV, and Fenton/TiO 2 /UV methods. RR2 concentration was varied between 150-300 ppm. As the results, RR2 concentration from 150-300 ppm does not significantly affect the percentage of color degradation. However, at high concentration of 250 and 300 ppm, the percentage of COD degradation decrease by increasing concentration of RR2. When using 150 ppm of RR2, the highest COD and color degradation of 98.8 % and 89.5 %, respectively were achieved by using the Fenton/TiO 2 /UV methods.
