Effects of different feed doses of Majapahit leaves (Crescentia cujete L.) on the growth of Nile tilapia (Oreochromis niloticus)

Abstract

Phytochemical test results of Majapahit leaf extract contain active ingredients saponins, tannins, steroids and triterpenoids which have in vitro potential as antibacterial and from the results of GCMS analysis in previous studies. Majapahit leaves contain active ingredients such as 2-Methoxyl4-vinylpheol, Thiosulfuric acid, Octadec9-enoicacid, n-Hexadeconoic acid which has the potential as an antibacterial insilico. This study aims to determine the effect of the addition of Majapahit leaf powder (Crescentiacujete L.) in feed with different doses to the growth of tilapia (Oreochromis niloticus) The parameters observed in this study were the growth of tilapia weight by treating different doses of majapahit leaf powder with doses A (7.5%), B (10%), C (12.5%) and D (0%). To find out the weight of the fish, sampling was done every 5 days. The results showed the best absolute weight growth in treatment C (12.5%) which was 21.33 g higher than the control treatment which was 10.33 g.
