Abstract
Aquaculture is an effort to look for profits through the maintenance and breeding of aquatic organisms in an environment. Agricultural waste that is not utilized by humans can actually be used as a mixture in the manufacture of tilapia fish feed as long as it has sufficient protein content such as old cassava leaves. This study aims to determine whether cassava leaf flour (Manihot esculenta C.) can be used as a mixture of fish meal ingredients in the manufacture of tilapia fish feed (Oreochromis niloticus) and at what concentrations of artificial feed made from a mixture of fish meal and cassava leaf flour is effective as a feed parrot fish. This research was conducted in the village of Sidodadi Asri, Jati Agung, South Lampung using RAL method with four treatments and two repetitions, namely commercial feed, mixed feed 75% Fish meal: 25% cassava leaf flour, 50% fish meal: 50% cassava leaf flour , and 25% fish meal: 75% cassava leaf flour will be tested on tilapia for 30 days. The parameters observed were the growth of tilapia, survival rate, protein content in feed, and pond water quality. From the results of research on the effectiveness of fish meal and cassava leaf flour (Manihot esculenta C.) as tilapia fish feed (Oreochromis niloticus) showed artificial feed with a mixture of 75% fish meal and 25% cassava leaf flour gave the most optimal growth results.
