Komparasi Pakan Komersial dan Pakan Substitusi 50% Tepung Daun Singkong Terfermentasi terhadap Panjang dan Bobot Ikan Nila

Abstract

Tilapia (Oreochromis niloticus) farming requires feed to support fish growth. Currently, feed is mainly sourced from commercial products; however, their relatively high cost reduces the profitability for farmers. A substitute feed incorporating 50% fermented cassava leaf meal as a feed ingredient can reduce commercial feed costs. This study aimed to compare the effects of commercial feed and a substitute feed containing 50% fermented cassava leaf meal on the length and weight of tilapia. The research employed a completely randomized design with two treatments: commercial feed (K) and a 50% fermented cassava leaf meal substitute (P), each replicated three times. The study was conducted over 28 days. Data on fish length and weight were collected weekly (week 0, 1, 2, 3, and 4). The results showed that treatment P had higher average final length and weight than treatment K. The average final length for treatment P was 9.54 cm, while treatment K reached 8.84 cm. The average final weight for treatment P was 15.12 g, compared to 11.61 g for treatment K. Independent t-test analysis indicated significant differences between treatments K and P in both length and weight parameters from week 1 to week 4. The addition of 50% fermented cassava leaf meal as a feed substitute proved more effective in improving the growth (length and weight) of tilapia than the control feed.
