Abstract: Garam dengan kandungan natrium yang tinggi dapat menyebabkan masalah kesehatan, khususnya hipertensi. Alternatif dari hal tersebut, Grateloupia angusta dapat digunakan sebagai sediaan bahan baku garam diet. Penelitian ini bertujuan menentukan karakteristik rumput laut G. angusta, mendapatkan garam rumput laut dengan perbandingan pelarut dan tepung rumput laut yang optimum yang memiliki kadar NaCl <60%, rasio Na:K yang rendah, dan hasil rendemen dan aktivitas antioksidan yang tinggi. Konsentrasi bahan baku terhadap pelarut yang digunakan yaitu 1:5, 1:10, dan 1:15 (b/v). Penambahan konsentrasi pelarut berpengaruh nyata (p<0,05) terhadap nilai rendemen, mineral, %NaCl, total fenol dan aktivitas antioksidan antioksidan garam. Konsentrasi pelarut terbaik yaitu garam 1:15 yang menghasilkan nilai rendemen 20,9 ± 2,30%, rasio Na:K 0,90, %NaCl 60,36 ± 0,15%, total fenol 1.543,37 ± 2,35 mg/GAE/g, aktivitas antioksidan CUPRAC 37,30 ± 1,43 μg/mL asam askorbat/g sampel, dan ABTS dengan nilai IC50 150,6 ± 8,81 μg/mL.
Salt with a high concentration of sodium content can cause health problems, particularly hypertension. As an alternative to this matter, G. angusta can be used as a raw material for dietary salt. This study aims to determine the characteristics of G. angusta seaweed, to obtain seaweed salt with the optimum ratio of seaweed flour and solvent containing NaCl < 60%, a low ratio of Na: K, and a high result in yield and antioxidant activity. The concentration of raw material on the solvent used is 1:5, 1:10, and 1:15 (b/v). The addition of solvent concentration increased the value of yield, minerals, NaCl, total phenol, and antioxidant activity significantly (p 0,05). The best solvent concentration is 1:15, which produces a yield value of 20.9 ± 2.30%, Na:K ratio of 0.90, % NaCl 60.36 ± 0.15%, total phenol 1.543,37 ± 2.35 mg/GAE/g, CUPRAC antioxidant activity 37.30 ± 1.43 μg/mL ascorbic acid/g sample, and ABTS with an IC50 of 150.6 ± 8.81 μg /mL.
