    Degradation of methanil yellow solution had been done by photocatalytic using CuO as catalyst. CuO was synthesized by precipitation method using as copper nitrate (Cu(NO3)2.3H2O) with precipitator NaOH molar ratio of precursors 1:1 M at calcination temperature 700 ℃ until 1 hour and characterized by X-ray Diffraction (XRD). The result obtained were analyzed using XRD and size of crystallinity of copper oxide (CuO) was examined with Scherrer equation obtained crystal size of CuO was 67,37 nm and result of degradation test from methanil yellow obtained optimum mass of CuO is 0,008 g, optimum time is 60 minute with percentage degradation 20,19% and 16,90%.
