This study aims to determine the effect of time variation and catalyst variation on peat swamp degradation. UV-Vis spectrophotometer was used to calculate the absorbance concentration of peat swamp air before and before degradation. The results showed that the highest percentage of peat swamp water degradation was 26.81% at 120 minutes using a ZnO catalyst. The highest degradation of peat swamp water was at 21.99% with a mass catalyst of 0.3 grams of ZnO", }
