Healthy salt can be produced from seaweed. Green seaweed Ulva lactuca and Chaetomorpha sp. have the potential to be used as low-sodium salt. The objective of this study was to determine the influence of green seaweed U. lactuca and Chaetomorpha sp. on the characteristics of seaweed salt based on %NaCl, Na/K ratio, and antioxidant activity. Seaweed salt was produced by soaking seaweed flour in distilled water (1:10), extracted at 40 C for 10 minutes, dried with dehydrator at 60 C for 48 hours, and the crystallized samples were ground into a seaweed salt. U. lactuca seaweed salt with yield of 23.67%, Na/K ratio of 1.74, %NaCl of 57.36%, total phenolic content of 466.13 mg GAE/g sample, IC50 value (ABTS) of 147.54 μg/mL, and antioxidant capacity (CUPRAC) of 40.04 μmol ascorbic acid/g seaweed salt. Chaetomorpha sp. salt with yield of 17.33%, Na/K ratio of 1.63, %NaCl of 61.45%, total phenolic content of 677.78 mg GAE/g sample, IC50 value of 95.40 μg/mL, and antioxidant capacity of 59.20 μmol ascorbic acid/g seaweed salt. U. lactuca has low %NaCl and moderate antioxidant activity. Chaetomorpha sp. has high %NaCl but strong antioxidant activity.
