- Artificial feed using local raw material is one of the efforts to reduce the production cost. Tofu waste is the local raw material that can be use as raw material for the manufacture of feed. The purpose of this research is to determine the best percentage of the formulated feed from the tofu waste for substitution of commercial feed for catfish fry. This research use a Completely Randomized Design (CRD), which consists of five treatments and three replications, namely P1: 0% feed containing tofu waste and 100% commercial feed, P2: 25% feed containing tofu waste and 75% commercial feed, P3: 50% feed containing tofu waste and 50% commercial feed, P4: 75% feed containing tofu waste and 25% commercial feed P5: 100% feed containing tofu waste and 0% commercial feed. The observed parameters are growth, feed efficiency, survival, and water quality. The result showed that tofu waste feed was able to substitute commercial feed up to 50% (P3 treatment) which resulted absolute weight growth 4.77 g, absolute length growth 1.99 cm, feed efficiency 79.16%, and survival rate 95.24%. Water temperature of fish range 26.9– 31.1oC, pH 5.76 – 6.90, dissolved oxygen 5.65 – 6.25 mg.L-1, and ammonia 0.01 – 0.24 mg.L-1.
