Penelitian ini berjuan untuk dapat mengetahui efektivitas pengobatan ikan nila (oreochromis niloticus) yang terinfeksi bakteri a. hydrophila dengan menggunakan ekstrak daun teh hijau (camellia sinensis l.). rancangan percobaan yang digunakan adalah rancangan acak lengkap (ral) dengan lima perlakuan dan tiga ulangan. perlakuan yang digunakan adalah perendaman ikan nila yang terinfeksi bakteri a.hydrophila dalam ekstrak daun teh hijau dengan dosis p0 (ekstrak daun teh hijau 0 ppm), p1 (ekstrak daun teh hijau 0 ppm+ infeksi bakteri a.hydrophila), p2 (ekstrak daun teh hijau 20 ppm + infeksi bakteri a.hydrophila), p3 (ekstrak daun teh hijau 40 ppm + infeksi bakteri a.hydrophila) dan p4 (ekstrak daun teh hijau 60 ppm + infeksi bakteri a.hydrophila). hasil uji anova pengobatan ikan nila yang terinfeksi bakteri a.hydrophila menunjukkan ekstrak daun teh hijau berpengaruh (p

This study aims to determine the effectiveness of treatment of tilapia (Oreochromis niloticus) infected with A. hydrophila bacteria using green tea leaf extract (Camellia sinensis L.). The experimental design used was a complete randomized design (CRD) with five treatments and three replicates. The treatment used was immersion of tilapia infected with A.hydrophila bacteria in green tea leaf extract with doses of P0 (0 ppm green tea leaf extract), P1 (0 ppm green tea leaf extract + A.hydrophila bacterial infection), P2 (20 ppm green tea leaf extract + A.hydrophila bacterial infection), P3 (40 ppm green tea leaf extract + A.hydrophila bacterial infection) and P4 (60 ppm green tea leaf extract + A.hydrophila bacterial infection). The results of the ANOVA test on the treatment of tilapia infected with A. hydrophila bacteria showed that green tea leaf extract had an effect (P < 0.05) on the survival of tilapia. The dose of green tea leaf extract as much as 20 ppm is known to treat fish with the highest survival rate of 76.66%.
