EFEKTIVITAS SERBUK DAUN TANAMAN KAYU MANIS (Cinnamomum burmanii) TERHADAP DIFERENSIAL LEUKOSIT DAN AKTIVITAS FAGOSITOSIS IKAN NILA (Oreochoromis niloticus) YANG DIINFEKSI Streptococcus agalactiae

Abstract

The main problem in the cultivation of tilapia is the attack of bacterial disease Streptococcosis
caused by Streptococcus agalactiae bacteria. Alternative measures to prevent the disease of
Streptocococis can be through the use of phytopharmaca materials. One of the ingredients of
phytopharmaca can be used is cinnamon plant. Cinnamon leaves contain several types of active
substances such as tannins, eugenol, safrole, calcium oxalate, resin, saponins, tanners, and
sinamaldehid. The objective of the study of effectiveness of leaf powder of cinnamon plant to
leukocyte differential and phagocytic activity in tilapia (Oreochromis niloticus) infected by
Streptococcus agalactiae is to know the influence and dosage of cinnamon leaf powder in feed
toLeukocyte Differentiation and Phagocytosis Activity Postcainfection Streptococcus agalactiae
in tilapia (Oreochromis niloticus). This research used 3treatment 4 replication and control with
dose K- = challenge test, K+ = without test challenge, A = dose 0,25%, B = dose 0,5%, C = 1%.
The parameters observed are Leukocyte Differential and Phagocytosis Activity. Dosage 0.5%
addition of leaf powder cinnamon plant on feed is the best dose. Giving of cinnamon leaf powder
in feed influenced to increase of leukocyte difference especially on monocyte cell and neutrophil
cell was significantly different (P>0,05) than K+ without addition of cinnamon leaf powder
while phagocytic activity had an effect on Streptococcus agacatiae.
