The presence of scallop shells, one of the marine products, increases the problem of solid waste disposal. This material is disposed to landfill without proper use, making it necessary to develop natural coagulant made from scallop shells. This research aimed to investigate the ability of scallop shells as a natural coagulant to remove turbidity. The scallop shell was used to produce chitosan, then adopted as a natural coagulant compared to a commercial product. Water turbidity, river water, and batik wastewater were examined using different coagulant doses, solution pH, and turbidity concentration. Based on data from this study, scallop shell-based chitosan has a high ability to reduce turbidity concentration in water. To remove artificial turbidity in water (14 NTU), the optimum coagulant dose was 150 mg/L and solution pH was 6. The ability of natural coagulants to remove river water turbidity (81 NTU) and batik was 72% and 87% respectively. The performance of commercial coagulant to remove artificial turbidity, river water, and batik wastewater was similar to the natural coagulant, making this novel natural coagulant a promising coagulant for water and wastewater treatment in the near future. Furthermore, massive production of natural coagulant can also solve the problem of scallop shell solid waste generation.
