Feed is one of the important components in fish farming as a source of material and energy, feed is also the largest component (50-70%) which causes an increase in production costs. Therefore, to reduce feed production costs is to mix inexpensive and easily accessible natural feed with a high enough protein content. During the harvest season the avocado is abundant and avocado seeds are disposed of as waste. This study aims to determine the effect of a combination of avocado Perseaa mericana M. and pumpkin Cucurbita moschata D seed on the growth and feed efficiency of Osphronemus gouramy Lac. The design used non-factorial Completely Randomed Design consisting of 4 treatments and 6 replications: P0 (control feed), P1 (40 grams of avocado seed feed + 40 grams of pumpkin seeds + 20 grams of mixed ingredients), P2 (20 grams of avocado seed feed + pumpkin seeds 60 grams + 20 grams of mixed ingredients) and P3 (60 grams of avocado seed feed + 20 grams of pumpkin seeds + 20 grams of mixed ingredients). Data analysis used Analysis of variance and Duncan’s test using SAS 9.3.1 software. The results showed that giving a combination of avocado seeds and pumpkin seeds can increase the growth of gouramy. The highly effective growth was found in P2 feed of 11.86 grams with a growth rate of 2.69% / day, while low growth occurred in the P3 treatment of 9.46 grams with a growth rate of 2.11% per day. The proximate test of the test feed showed that the highest protein was found in P2 feed, namely 25.01%. The best feed efficiency was found in P2 feed which had 6.91% crude fiber, and the highest protein content in P2 was 18.36%. It concluded that there was an effect of a combination of avocado and pumpkin seed feed on the growth and feed efficiency of Gouramy. Avocado and pumpkin seeds supplementation can be used as ingredients fish feed.

Feed is the biggest component (50-70%) which causes an increase in production costs, to reduce feed production costs is to mix inexpensive and easily accessible natural feed with a high enough protein content. This study aims to determine the effect of a combination of avocado (Persea americana M.) and pumpkin (Cucurbita moschata D.) seeds on the growth of  nile tilapia (Oreochromis niloticus L.). The design used non-factorial RAL consisted of 4 treatments and 6 replications, namely P0 (control feed), P1 (40 grams of avocado seed feed + 40 grams of pumpkin seeds + 20 grams of mixed material), P2 (20 grams of avocado seed feed + 60 grams of pumpkin seeds + 20 grams of mixed ingredients) and P3 (60 grams of avocado seed feed + 20 grams of pumpkin seeds + 20 grams of mixed ingredients). Data analysis using ANOVA. The results showed that feeding increased the growth of tilapia. In tilapia, a very effective growth was found in P2 feed of 16.44 grams with a growth rate of 3.12% / day. The conclusion of the study indicated that there was an effect of the combination of avocado and pumpkin seeds on the growth of tilapia.
