EFEKTIVITAS EKSTRAK DAUN PACAR AIR (IMPATIENS BALSAMINA L.) UNTUK MENINGKATKAN RESPON IMUN NON SPESIFIK IKAN NILA (OREOCHROMIS NILOTICUS)
ABSTRACT: The objective of
this research was to determine the most
effective dose and the best induction time of
Impatiens balsamina extract in enhancing nonspesific immune response of
nile tilapia (Oreochromis niloticus).
The tested fish were nile tilapia, 14-16 cm in length, and 39-42 g in weight, obtained from Balai
Pengembangan dan Pembinaan Pembudidayaan Ikan (BP3I) Tateli. The research was designed in 2x4 factorial in
completely randomized design. There
were two factors tested
in this research, the dose
and time. There were four levels of dose, A1 = 0 mg/mL extract, A2= 30 mg/mL extract,
A3= 50 mg/mL extract, A4= 70 mg/mL extract; and there were two levels of time, B1= 7 days after injection and B2=14 days
after injection. The extract was injected
intramuscularly with a dose of 0.2 mL per fish. Data collected in this research was the
immune parameters (total leucocyte count and phagocytosis activity). The
results showed that the most effective dose in enhancing nonspesific immune
response was A1=50 mg/mL extract and
the best induction time was B1= 7 day
after injection. The results also
indicated that there was
significant interaction between dose and time in influencing the total amount of leucocyte, but there was
not interaction in influencing the
phagocytic activities.
