      Abstract
      Rumput laut Sargassum sp. dapat dimanfaatkan sebagai bahan baku garam rumput laut. Garam rumput laut rendah natrium dan tinggi kalium yang memenuhi standar kadar NaCl garam diet. Penelitian ini bertujuan membandingkan karakteristik garam rumput laut dari Sargassum sp. dari tiga Perairan Sumatera yaitu Sargassum sp. Perairan Bangka, Aceh dan Padang berdasarkan NaCl dibawah 60%, aktivitas antioksidan baik, serta menentukan kualitas terbaik dengan rasio Na:K yang mendekati 1. Pembuatan garam rumput laut terdiri dari Sargassum sp. tiga perairan, masing-masing ditambahkan akuades 1:10, dipanaskan dalam water bath shaker pada 55 oC selama 10 menit, dan dikeringkan dengan oven pada 50 oC selama 24 jam. Garam Sargassum sp. dengan perairan terbaik berdasarkan keseluruhan parameter adalah Sargassum sp Perairan Padang dengan NaCl di bawah 60%, rasio Na:K mendekati 1, penerimaan sensori kenampakan dan rasa memiliki rata-rata 7 parameter suka. Hasil total fenol 251,20 mg GAE/g dan aktivitas antioksidan DPPH 79,10 ppm.
       
      Sargassum sp. can be utilized as a raw material for seaweed salt production. Seaweed salt is characterized by low sodium and high potassium contents, meeting the NaCl requirements for dietary salt. This study aimed to compare the characteristics of seaweed salt produced from Sargassum sp. collected from three coastal waters in Sumatra, namely Bangka, Aceh, and Padang based on NaCl content below 60%, antioxidant activity, and to determine the best-quality seaweed salt with a Na:K ratio close to 1. The seaweed salt was prepared by mixing Sargassum sp. samples from each location with distilled water at a ratio of 1:10 (w/v), followed by extraction in a water bath shaker at 55 oC for 10 minutes. The extract was dried in an oven at 50 oC for 24 hours. Based on the overall quality parameters, seaweed salt produced from Sargassum sp. collected from the Padang coastal waters exhibited the best characteristics, with NaCl content below 60%, a Na:K ratio close to 1, favorable sensory acceptance for appearance and taste (mean hedonic score of 7 “liked”), total phenolic content of 251,20 mg GAE/g and DPPH antioxidant activity (IC50 79,10 ppm).
