In this study the cultivation of microalgae using peat water and the addition of NaNO3 was 1 g / l; 1.25 g / l and 1.5 g / l. Microalgae biomass produced from the cultivation process is used as animal feed. The kinetics of the Logistic model and the Monod model are used to predict the growth of microalgae in the cultivation process. The results showed that the addition of 1.5 g / l NaNO¬3 prod…
