Abstract
This research was conducted to prove the phenolic compounds contained in the bark akway (Drymis piperita)on blood hematology of tilapia. In this study we used the size of the fish with a length of 5 cm, 7 cm and 9cm, with a dose treatment of akway bark extract namely 0.09 ppm, 0.9 ppm 9 ppm, 0.112 ppm, 1.12 ppmand 11.2 ppm and carried out for 14 days observation. The analysis was carried out on the hematologicalcomponents which included erythrocytes and hemoglobin. The results showed that at the end of theobservation the number of erythrocytes at the size of fish 5 cm = 1134.30 ± 6,739, fish size 7 cm = 1208.30 ±4,138 and at fish size 10 cm = 1272.79 ± 3,928. The average hemoglobin value at the end of the observationfor fish size 5 cm = 6.17 ± 0.153, fish size 7 cm = 7.10 ± 0.100 and fish size 10 cm = 7.80 ± 0.000. Thus, thereis difference in the number of erythrocytes and hemoglobin between treatment doses.
