Abstract: Abstract Demand for food consumption is increase rapidly in the coming decades. Microalgae could substitute conventional crop products for food application. Single cell protein from microalgae gain more attention due to low-cost but swift production. During microalgae cultivation, some parameters must be considered, e.g. light intencity, temperature, oxygen dan carbon dioxide, acidity, salinity, and nutrients. Several cultivation media are commonly used in the microalgae cultivation process. There are many uses of microalgae in the food sector, not limited only to feed. So that the use of fertilizer media used during microalgae cultivation must also be considered so that it is not harmful to humans. One of them is using AB Mix hydroponic fertilizer. The purpose of this cultivation is to provide raw materials for microalgae which can then be used for further research. In the microalgae cultivation process, color changes indicate that the density of microalgae cells has increased. If the cell density is high, the resulting color will be more visible. In Chlorella vulgaris, the growth increased rapidly on the 10th day compared to Bold's Basal Medium. In Spirulina sp. Microalgae, growth increased rapidly on 3rd day compared to Bold's Basal Medium. Meanwhile, the microalgae Dunaliella salina showed a gradual increase in growth on 6th day compared to Bold's Basal Medium.
