Tujuan penelitian ini untuk melihat pengaruh perendaman ikan di dalam air asam sunti dan penyimpanannya pada suhu ruang terhadap karakteristik ikan. Penelitian ini menggunakan Rancangan Acak Kelompok Faktorial dengan 2 faktor yaitu faktor waktu perendaman (W), yang terdiri dari 3 taraf (W1 : 30 detik, W2 : 5 menit, W3 : 10 menit) dan lama penyimpanan (S), yang terdiri dari 2 taraf (S1 : 0 jam, S2 : 2 jam). Hasil penelitian menunjukkan bahwa karakteristik air asam sunti pada uji pH memiliki rataan yaitu 1,27, total asam 49% dan total bakteri asam laktat  5,1×104 CFU/gram. Nilai pH ikan setelah direndam air asam sunti 5,22-5,65 dengan rataan 5,43 dan nilai protein terlarut berkisar antara 18,42-18,74% dengan rataan 18,74%.Dari penelitian didapatkan bahwa waktu perendaman (W) berpengaruh nyata (P≤0,05) terhadap nilai protein terlarut dari ikan namun berpengaruh tidak nyata (P0,05) terhadap nilai pH ikan, uji deskriptif aroma dan tekstur ikan. Lama penyimpanan (S) berpengaruh sangat nyata (P≤0,01) terhadap nilai pH ikan setelah perendaman namun berpengaruh tidak nyata (P0,05) terhadap uji deskriptif aroma dan tekstur ikan. Interaksi waktu perendaman dengan lama penyimpanan berpengaruh nyata (P≤0,05) terhadap nilai pH ikan namun berpengaruh tidak nyata terhadap uji deskriptif aroma dan tekstur ikan.Waktu perendaman ikan di dalam air asam sunti selama 10 menit dapat menghambat kenaikan pH ikan selama penyimpanan sampai 2 jam. Semakin lama perendaman ikan di dalam air asam sunti maka semakin tinggi protein terlarut dari ikan.  Abstrack.
