<![CDATA[Milkfish is the result of ponds, where the cultivation of this animal was initially a side job for fishermen who could not go to sea. That is why, traditionally, ponds are located on the coast. The high price of commercial feed is the main obstacle; therefore, using breadfruit leaves (Artocarpus communis) as a fish feed additive is necessary. This research aims to: 1) Measure the protein, fat, carbohydrate, crude fiber, ash, and water content in feed using breadfruit (Artocarpus communis) leaves with different formulations. 2) Knowing how adding fish feed additives with different formulations affects survival, growth, and fish protein content. This research used a Completely Randomized Design (CRD) method with 4 treatments and 3 replications. The differences in treatment were by differentiating the composition of 20% protein content and the same additives (P1 = 20%), the composition of 25% protein content and the same additives (P2 = 25%), the composition of the protein content is 30%, and the same additives (P3 = 30%), the composition of the protein content is 40% and the same additives (P4 = 40%). The research results show that Providing different types of feed had a very significant effect (P<0.01) on absolute individual growth, relative growth, survival, and feed conversion of milkfish (Chanos-chanos Forskal) and had a significant effect (P<0.05) on daily growth rate. , but did not affect the length growth of milkfish (Chanos-chanos Forskal). The highest daily growth rate, absolute individual growth, and relative growth were achieved by PI treatment, namely by feeding anchovy fish. The highest survival was achieved by treatment P2 (82%), followed by treatment P3 (77%). The lowest feed conversion was achieved in treatment P3 (2.02%), then feed conversion will increase further in treatment P2 (2.66%), treatment P4 (2.76%), and treatment P1 (2.93%). The water quality between treatments was in a range that supported the growth of milkfish (Chanos-chanos Forskal). Utilization of breadfruit leaves as an additive with the right concentration to be used as fish feed.]]>
