      Abstract
      Rumput laut hijau Ulva lactuca dan Chaetomorpha sp. yang terdapat di Indonesia dapat dimanfaatkan sebagai sumber bahan baku pembuatan garam rumput laut. Tujuan penelitian ini untuk menentukan pengaruh rumput laut hijau U. lactuca dan Chaetomorpha sp. terhadap karakteristik garam rumput laut yang memiliki kadar NaCl <60%, rasio Na:K yang rendah, dan aktivitas antioksidan yang tinggi. Garam rumput laut dihasilkan dari filtrat ekstraksi tepung rumput laut dengan pelarut akuades konsentrasi 1:10, dan dipanaskan dalam water bath suhu 40ºC selama 10 menit dan dikeringkan menggunakan oven suhu 60ºC selama 48 jam. Garam U. lactuca menghasilkan rendemen 23,67%, rasio Na:K 1,74, NaCl 57,36%, dan total fenol 466,13 mg GAE/g, serta aktivitas antioksidan (ABTS) 147,54 ppm, dan (CUPRAC) 40,04 µmol/g. Garam Chaetomorpha sp. menghasilkan rendemen 17,33%, rasio Na:K 1,63, NaCl 61,45%, dan total fenol 677,78 mg GAE/g, serta memiliki aktivitas antioksidan (ABTS) 95,40 ppm, dan (CUPRAC) 59,20 µmol/g garam.
       
      Green seaweed Ulva lactuca and Chaetomorpha sp. found in Indonesia can be used as a source of raw material for making seaweed salt. The purpose of this study was to determine the effect of green seaweeds Chaetomorpha sp. and U. lactuca on the characteristics of seaweed salt which has <60% NaCl level, low Na:K ratio, and high antioxidant activity. Seaweed salt is produced from seaweed flour extraction filtrate with distilled water with a concentration of 1:10, and heated in a water bath at 40°C for 10 minutes and dried using an oven at 60°C for 48 hours. U. lactuca salt produces a yield of 23.67%, Na:K ratio 1.74, NaCl 57.36%, and total phenol 466.13 mg GAE/g, and antioxidant activity (ABTS) 147.54 ppm, and (CUPRAC) 40.04 µmol/g. Chaetomorpha sp. salt produces a yield of 17.33%, Na:K ratio 1.63, NaCl 61.45%, and total phenol 677.78 mg GAE/g, and has antioxidant activity (ABTS) 95.40 ppm, and (CUPRAC ) 59.20 µmol/g salt.
