Abstract

Light has been the main limiting factor in mass culturing of Spirulina platens is . Therefore this study has been conducted to determine photoperiod that promotes the fastest growth. Spirulina platensis was cultured in four type of photoperiod; 12L:12D, 9L:15D, 6L:18D, and 3L:21D. Although the result of the ANOVA analysis shows that there was no significant effect on the growth rate of the Spirulina platensis, based on the growth and growth rate result, there was a slight indication of difference in growth can be seen at the end of the culture period between the treatments used. Spirulina platens is shows much better growth and specific growth rate under 12L:12D treatment compare to other treatments. Spirulina platensis obtained a 125.89% increased in dry weight and 0.0905 d-1 growth rate. Based on these results, a conclusion that can be drawn is that 12L: 12D treatment promotes the best growth rate compare to other treatment that was used in this study.
