Eucheuma cottonii, seaweed, is one of marine products with high economic value which can be seen from increasing market demand. The study of using different commercial fertilizer in seaweed aquaculture is one of possible effort to increase seaweed production. The method used in this research was experimental applying randomized complete design. All samples are deeped for 15 minutes in different composition of NPK fertilizers before cultivated in floating raft method. The treatments are NPK ratio of 10:55:10; 15:15:15; 46:0:0; 60:20:10 and without fertilizer as control. Seaweed mass for cultivation was 80 grams observe at every week during five week.
