This study aims to identify the level of use of coconut testa resulted from Neurospora sitophila fermentation in the most effective formulation of feed for the growth of red tilapia to providing a high survival rate. This research was conducted from December 2019 to February 2020 at the Building 4 of Aquaculture and Hatchery Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University. It applied an experimental method using a completely randomized design (CRD) with five treatments and three replications. The treatment used feed formulation with different concentration of coconut testa content of A (0% B (5% C (10% D (15% and E (20% The parameters measured include absolute weight growth, survival rate, and water quality. Absolute weight growth, and fish survival rates were analyzed using ANOVA with an error rate of 5% Meanwhile, the water quality was analyzed using descriptive comparative analysis. The result showed that the use of 20% coconut testa produced by N. sitophila fermentation produces an optimal growth rate of red tilapia which is 0,74% with an absolut value of 0,77 gram.
