ABSTRACT
Global warming gives phytoplankton a significant role in reducing carbon. C. calcitras is a phytoplankton which utilizes carbon dioxide for growth and the formation of secondary metabolites in order to survive. The purpose of this study was to determine the effect of differences in duration on growth, lipid content, carotenoids and chlorophyll-a in C. calcitrans and to determine the optimal duration. An experimental method with statistical analysis using ANOVA was used in this study. The treatments implemented were the addition of carbon dioxide for 0, 2, 4, 6, 8, 10, 12, and 14 minutes with a volume of carbon dioxide addition of 3 bps. The results showed that the addition of carbon dioxide had a significant effect (P<0.05) on the value of lipids, growth, carotenoids and chlorophyll-a. The highest density value was obtained in Treatment for 2 minutes to increase growth with the highest total value of 2,927,500 cells/ml. The best treatment to increase lipids was Treatment for 12 minutes with lipid content of 63.33% and lipid productivity of 1.82 mg/l/day. The best treatment to increase carotenoid content was Treatment for 4 minutes with carotenoid content of 2.20 g/mL and chlorophyll-a content of 1.4431 g/mL. Optimal treatment differences to obtain the highest value of each parameter differ from each other, depending on the synthesis and physiological processes of C. calcitrans.
