      Abstract
      Bawang dayak (Eleutherine palmifolia (L.) Merr.) merupakan tanaman herbal yang berpotensi sebagai pangan fungsional, namun kajian mengenai pengaruh kesegaran bahan dan kondisi perebusan terhadap karakteristik air rebusannya masih terbatas. Penelitian ini bertujuan menganalisis pengaruh kesegaran bahan dan kondisi perebusan terhadap karakteristik fisikokimia dan aktivitas antioksidan serta menentukan kombinasi perlakuan terbaik. Penelitian menggunakan Rancangan Acak Lengkap (RAL) pola faktorial dengan dua faktor, yaitu kesegaran bahan (segar dan kering) serta kondisi perebusan (penyeduhan air mendidih suhu 98– 100°C selama 30 menit dan perebusan suhu konstan 98–100°C selama 5, 10, 15, dan 20 menit). Hasil penelitian menunjukkan bahwa kesegaran bahan, kondisi perebusan, dan interaksinya berpengaruh nyata terhadap warna dan total padatan terlarut, sedangkan pH dipengaruhi oleh kedua faktor tanpa interaksi. Aktivitas antioksidan (AEAC) tidak berbeda nyata antarperlakuan. Perlakuan bawang dayak segar yang direbus selama 20 menit merupakan kombinasi perlakuan terbaik berdasarkan metode De Garmo.
       
      Dayak onion (Eleutherine palmifolia (L.) Merr.) is a herbal plant with strong potential as a functional food. However, research on how raw material freshness and extraction conditions affect its decoction properties remains limited. This study evaluated the effects of material freshness and decoction conditions on the physicochemical characteristics and antioxidant activity of Dayak onion decoction. It also identified the optimal processing combination. The study applied a Completely Randomized Design (CRD) with a two-factor factorial arrangement. The first factor was material freshness (fresh and dried). The second factor was the processing condition (infusion in boiling water at 98-100 °C for 30 minutes and constant decoction at 98-100 °C for 5, 10, 15, and 20 minutes). The results showed that material freshness, decoction conditions, and their interaction significantly affected color and total dissolved solids. Both individual factors influenced pH without interaction. Antioxidant activity (AEAC) showed no significant difference among treatments. Based on the De Garmo method, decocting fresh Dayak onion for 20 minutes produced the best overall treatment combination.
