Research on water quality in test ponds based on the influence of the application of sago-based catfish food has been carried out in Udapi Hilir Village, Manokwari Regency. The effect of sago pulp composition was carried out on variations of rice bran: fish meal: sago pulp was 1:1:0.5, 1:1:1, 1:1:1,5, and rice bran: the fish meal was 1:1. This research explains the water quality of test ponds using physical and chemical parameter monitoring methods. The results of this study contain several chemical and physical parameters that exceed the quality standard threshold. The results of the proximate analysis showed that adding sago pulp provided a chemical value of the feed that was still following the recommended standards. The results of water quality tests carried out for 4 weeks showed an increase in TDS levels, without draining the test pool during the research. The average Nitrate (NO3 -) has increased but is still below the quality standard of 10 mg/L. Nitrate (NO3 -) concentrations are rising in all ponds for all treatments. Nitrate levels impact fish growth because they can lower water oxygen levels. Overall, the application of sago pulp as a raw material for catfish feed results in pond water quality that is still within the pond water quality standards so it has the potential as an alternative feed raw material.
