Abstract
Abstract. Nannochloropsis sp. has been used as natural feed because it has high nutrition that is good for fish larva growth and development. However, the Nannochloropsis sp. availability continually is in insufficient amount and this often becomes a problem in culturing because this is difficult to culture in mass volume. The objective of this research was to make Nannochloropsis sp. paste and to test the paste quality based on the life endurance of Nannochloropsis sp. cells from isolate of Lampung Mangrove Centre in intermediate scale culture by using different fertilizer combination and NaOH doses. This research used factorial completely randomized design with two treatments and three repetitions. The first treatment was administration of agricultural fertilizer combination of (P) urea 40 ppm, ZA 20 ppm, and TSP 5 ppm, and Conway (C) technical fertilizer as control. The second treatment is the administration of NaOH doses of: 100 ppm, 125 ppm, 150 ppm, and 175 ppm. Data were analyzed by using One Way Analysis of Variance (ANOVA), and Least Significant Difference test with α = 0.05 was performed whenever any significant difference was found. The research result showed that Nannochloropsis sp. paste from isolate of Lampung Mangrove Centre had highest life endurance level with Conwy technical fertilizer and dose of NaOH 100 ppm with population density of 18066666.67 x 104 cell/mL
