Kata kunci : Nannochloropsis oculata, total lipid, fotoperiod Photoperiod has important role on the photosynthesis process of microalgae Nannochloropsis oculata . Photoperiod also influences on total lipid content of various microalgae. This research has purpose to examine the effect of nutrient phosphate and nitrate composition to the total lipid content of N. oculata belong to class Eustigmatophyceae. There were four treatments of photoperiod as follows; (a) photoperiod A (4:20 hour light:dark);(b) photoperiod B (8:16 hour light:dark); photoperiod C (12:12 hour light:dark); (and (d) photoperiod D (24 hour light). There were three replicates for each treatment. The volume of culture medium was 250 mL for each treatment with continuously aeration and illumination (3000 lux). According to the research, the highest total lipid content of N. oculata had been found on the treatment of photoperiod 12:12 hour light:dark 31,8 ± 3,03 %-dw, and then followed by photoperiod 8:16 hour light dark as amount 25,2 ± 2,19 %-dw and 24 hour light (23,2 ± 1,99 %-dw), and then followed by photoperiod 24 hour light. Differences of photoperiod 8:16 hour light:dark and photoperiod 12:12 hour light:dark on culture medium of N. oculata showed result that there were differences of total lipid content on the stationary and exponential phase. The highest percentage of total lipid was fund in cell of N. oculata grown under treatment of photoperiod 12:12 hour light:dark. The treatment of photoperiod 8:16 hour light:dark and 12:12 hour light:dark in the N. oculata culture showed result that the total lipid content on stationary phase was greater than exponential phase.
