Nannochloropsis is a microalga that is used as feed and can be cultured intensively. One of the obstacles in its culture is high-cost production. Innovations that can be applied to overcome this problem is the utilization of wastewater from whiteleg shrimp ( Litopenaeus vannamei ) aquaculture. The purpose of this study was to assess the population growth of Nannochloropsis sp. culture by using wastewater of whiteleg shrimp with different densities in a semi-mass culture. The research design used in this study was a completely randomized design with four treatments and three replications, namely treatment A (2.5 x 10 6 ind/ml), B (5 x 10 6 ind/ml), C (7.5 x 10 6 ind/ml), and D (10 x 10 6 ind/ml). The parameters measured were population density, nitrate, phosphate, pH, temperature, salinity, and light intensity. The results showed that the utilization of wastewater from whiteleg shrimp culture had a significant effect on the population growth of Nannochloropsis sp. Treatment A showed the best result with an increase in density by 119% (2.5 x 10 6 ind /ml to 5.49 x 10 6 ind/ml) at the adaptation phase, and 1012% (2.5 x 10 6 ind/ml to 27.8 x 10 6 ind/ml) at the exponential phase.
