The research is located in Pasir River, Jangkaran Village, Kulon Progo Regency. Landuse in Pasir River are dominated by shrimp ponds. Mangroves on the riverbank can reduce the concentration of nutrients in shrimp pond effluent. This study aims to determine the purification of shrimp pond effluent in the mangrove ecosystem by comparing the quality of shrimp pond effluent before and after passing through the mangrove ecosystem. The research method used is the field survey method and laboratory analysis. Water sampling and identification of mangrove characteristics were done purposively on 6 observation segments. Data analysis was performed graphically, descriptively, spatially, and comparatively. The results show that mangrove ecosystems can reduce concentration of nitrate and phosphat in shrimp pond effluent as evidenced by a decrease concentration of nitrate in segments 1 to 6. The nitrate concentration in the mangrove ecosystem and after passing through the mangrove are smaller than before passing the mangrove. The characteristics of mangroves that affect the purification process are species and density of vegetation. Species mangrove Rhizophora mucronata with higher vegetation density can reduce the concentration of nitrate in SPT 1 to 4 better than species Avicennia marina with lower density in segment 5.
