| Abstract | Microalgae cultivation can be done in closed system using photobioreactor and open system using raceway pond. Both systems have advantages and disadvantages. The purpose of this research was to compare the density, specific growth rate, biomass weight, and doubling time of microalgae Nannochloropsis sp. that was cultivated in open raceway pond and photobioreactor. Microalgae density result in open raceway pond increased from 6.64 x106 cell mL in day 0 to 139.89 x 106 cell mL in day 10 of observation, while in photobioreactor increased from 10.97 x 10 cells mL in day 0 of cultivation to 77.11 x 10 cells mL in day 10. Specific growth rate in open raceway pond were low while in photobioreactor increased exponentially between day 0 and day 1 of observation. Specific growth rate in open raceway pond in the second day was higher than in photobioreactor. Death phase reached faster in photobioreactor compared to open raceway pond. Biomass weight of Nannochloropsis sp. in photobioreactor was decreased from 0.2 gr L in day 0 to 0.16 gr L in day 10, while in open raceway pond they were increased from 0.21 gr L in day 0 to 0.33 gr L in day 10. Doubling time of Nannochloropsis sp. cultivated in open raceway pond (2.27) was faster than in photobioreactor (3.51). |
