Aquaculture wastewater often contains high levels of suspended solids and turbidity, which may negatively affect water quality and aquatic ecosystems if discharged without treatment. Although chemical coagulants are effective for suspended solids removal, their use is associated with environmental, economic, and sludge management concerns. However, limited studies have explored the use of sago waste as a natural coagulant for aquaculture wastewater treatment, particularly for turbidity and total suspended solids (TSS) removal. This study investigates the effectiveness of sago waste as a natural coagulant for aquaculture wastewater treatment and examines the effect of coagulant dosage on turbidity and TSS removal. Jar test experiments were conducted using aquaculture wastewater treated with sago waste at dosages ranging from 0.1 to 10 mg/L. Turbidity and TSS concentrations were measured before and after treatment to determine removal efficiency. The results showed that sago waste was able to reduce turbidity and TSS at all tested dosages. Turbidity removal efficiency increased from 16.97% at 0.1 mg/L to a maximum of 20.50% at 10 mg/L, indicating the optimal dosage for turbidity removal at 10 mg/L, while TSS removal showed limited variation, with the optimal dosage observed at 1 mg/L, achieving a removal efficiency of 13.86%. In conclusion, sago waste demonstrated greater effectiveness in turbidity reduction than in TSS removal and can serve as a sustainable and low-cost natural coagulant for preliminary treatment of aquaculture wastewater.
