N2 - Environmental quality protection is done by processing shrimp waste into materials of high use value, including liquid fertilizer. The value of N/P ratio in shrimp culture waste fertilizer is still relatively low so it needs to add urea as a source of nitrogen to increase the N/P ratio in fertilizer. The purpose of this research was to determine the optimal N/P ratio in shrimp culture waste fertilizer to the growth of Chlorella vulgaris. The research method used in this research was an experimental method, A completely randomized design with 5 treatments and 4 replications. The treatments used are giving different N/P ratios from shrimp culture waste fertilizer enriched by urea, with N/P ratio 10:1, 15:1 and 20:1, whereas Walne fertilizer with N/P ratio 17:1 and shrimp culture waste fertilizer with N/P ratio 5,5:1 as a control. Data analyze was processed use ANAVA and followed by DMRT. The results of the research showed that the using of different N/P ratios in shrimp culture waste fertilizer enriched by urea gave a significantly different effect on the population and growth rate with the highest population average of 1030x104 cell/ml and an average growth rate of 203x104 cell/ml/day during the exponential phase.
