Indonesia as a maritime country has high potential in developing microalgae. Microalgae in Indonesia have a high oil component of around 20-30%, for example Nitzschia palea (23%), Chlorella vulgaris (27%), and Euglena gracilis (20%). In addition to biofuel production, the microalgae species chlorella vulgaris can also be used as part of wastewater treatment. This paper aims to optimize the photo-bioreactor design for microalgae with multi-objective functions including exergy and economics. One method used is the Multi-Objective Multi-Verse Optimizer (MOMVO). MOMVO optimization is related to several objective functions with specified constrain. Objective functions and constraints will be resolved in the form of algorithmic functions. From the optimization results using the Multi-Objective Multi-Verse Optimizer (MOMVO), it can be concluded that the optimum exergy value is at 1292.5 cd and the pressure is 3.34 kPa with an exergy destruction value of 23,424.96 kW and a total cost of $ 42,744.85. While the optimum economic value is at 1292.51 cd and the pressure is 3.34 kPa with an exergy value of destruction of 23,726.82 kW and a total cost of $ 42,837.36.
