Abstract
The 17 days of culturing Chlorella to determine the effect in different light exposures at different light intensities in the production. The study has two factors were; Factor A= two light exposure (time); Factor B = two light intensities (lumens). Treatment 1 (400 lumens, 6 hours exposures); Treatment 2 (600 lumens, 6 hours exposures); Treatment 3 (400 lumens, 12 hours exposures); Treatment 4 (600 lumens, 12 hours exposures); The result showed that Treatment 4 (600 lumens, 12 hours exposures had a higher production among those other Treatments. Treatment 1 (400 lumens, 6 hours exposures) has a lowest production. Based on the study, it was therefore concluded that the use of light bulbs with 600 lumens light intensity combined with photoperiod of 12 hours was ideal for the maximum production of Chlorella. This study was limited on the production performance of Chlorella in a different light exposures (time) and different light intensities (lumens). It is recommended to add vermicast in cultute in same light intensities and exposures.
