The study was conducted aiming to test different fertilizer doses on the optimal growth rate of Eucheuma cottonii seaweed. The study was conducted from July to August 2016 in the waters of Ghonebalano Village, Duruka District, Muna Regency, Southeast Sulawesi. The study used NPK fertilizer with the composition of the element nitrogen (N) 15%, phosphate (P2O5) 15%, and potassium (K2O) 15%. The study used a Randomized Block Design (RBD) with 3 (three) levels of fertilizer doses and 3 (three)

While the treatments tested in the study were treatment A (without fertilizer/control), treatment B (fertilizer dose 1g/liter), and treatment C (fertilizer dose 2 g/liter). The results showed that the difference in fertilizer dose significantly affected the growth rate of Eucheuma cottonii seaweed. A dosage of 2 grams/liter of fertilizer gives the best rate of growth of Eucheuma cottonii seaweed while the water quality at the study site shows that it is still in the optimal range for the growth of Eucheuma cottonii seaweed.
