Abstract
Rhodamine B is a synthetic dye in the form of a powder, generally used for the purpose of changing colors in textile and paper factories. Rhodamine B is a chemical that is dangerous, absolutely should not be mixed in food, beverages and cosmetics, besides that rhodamine also has toxic properties so it must be degraded to reduce its toxicity. This research uses ZnO/Mn material which is synthesized using laser ablation in liquid (PLAL) technique as the degradation of rhodamine B waste. ZnO/Mn photocatalyst against rhodamine B dye. The results of the FE-SEM show that with the addition of Mn doping, the bond between the particles is getting better. ZnO/Mn with a variation of 0.1 mM obtained the best results for degradation, namely 89.474%, and the energy gap was 3.3196 eV.
