Abstract
Stingray liver oil extraction method (Dasyatis sp) using alkaline digestion method with the addition of 2% concentrated NaOH reagent and HCL to maintain pH 8-9 by heating at 50°C for 3 hours can produce a yield of 35.74±0.38%. then with the addition of 3% magnesol XL adsorbent and centrifuged for 15 minutes at a speed of 5000 rpm can improve the quality of stingray liver oil (Dasyatis sp) by producing an FFA value of 0.40%±0.02, PV of 2.37±0, 05 mEq/kg, p-anisidin 5.72±1.95 mEq/kg, TOTOX 8.27±1.80 mEq/kg, AV 1.74±0.01 mg NaOH/kg, clarity 75, 19±1.7%.Keywords
