The aim of this study was to determine toxicity value of rice bran extract with variation of solvents and extraction times. Rice bran extracts were tested its toxicity by BSLT method and its secondary metabolite by phytochemical test with reagents. Mortality data of shrimp larvae was analyzed by probit to determine LC50 values. Yield of ethanolic extract of rice bran for E1-20, E1-25 and E1-30 samples was 18.159, 19.132 and 18.280%, respectively. Rice bran extracts by ethyl acetate solvent (E2) and n-hexane (E3) gave different yields such as 8.302% (E2-20), 7.282% (E2-25), 9.18% (E2-30), 7.815% (E3-20), 7.125% (E3-25), and 7.279% (E3-30). All of rice bran extracts contained flavonoids, steroids and triterpenoids. LC50 values in ethanolic extract of rice bran for E1-20, E1-25 dan E1-30 samples were 613.258, 673.210 and 2217.255 ppm, respectively. Toxicity (LC50) values of ethyl acetate extract of rice bran were 1161.298 ppm (E2-20), 1170.774 ppm (E2-25) and 701.532 ppm (E2-30), while toxicity (LC50) values of n-hexane extract of rice bran were 592.901 ppm (E3-20), 617.425 ppm (E3-25) and 695.198 ppm (E3-30). Keywords: Rice bran, secondary metabolite, toxicity, ultrasonic method  Bekatul diekstrak menggunakan metode ultrasonik dengan variasi pelarut (etanol, etil asetat dan n-heksana) dan lama ekstraksi (20, 25 dan 30 menit).
