The development of seaweed cultivation method that support marine conservation needs to be done on Kemojan Island. The use of basket to cultivate seaweed can reduce the conflict between seaweed farmers and sea turtle protection compared to the longline method that used by local people on Kemojan Island at the present. The purpose of this study was to analyze the seaweed growth (E. cottonii ) using the basket method compared to the simple longline method. Seaweed cultivavtion was conducted for 21 days. We measured the growth variables include biomass growth and daily growth rate. This study proved that the simple longline method produces higher seaweed growth than the basket method. However, the simple longline method is more prone to harvest failure than the basket method. In the absence of disease, the growth of seaweed on the simple longline method was 1.8% per day, while in the basket method was 1.2% per day.
