Indonesia has a water area of 3.25 million km2, with an exclusive economic zone of 2.55 million km2, and a land area of only around 2.01 million km2. The vastness of its territorial waters means that Indonesia has great potential in the maritime and fisheries sector. Seaweed cultivation is one of the businesses carried out by many coastal communities. The seaweed that is cultivated is the Eucheuma cottonii type, this type of seaweed has fast growth, high economic value and produces carrageenan. One of the areas that produces Eucheuma cottonii seaweed cultivation in Eastern Indonesia is Southeast Maluku Regency and Tual City, which is the center for seaweed cultivation in Maluku Province.
Seaweed cultivation faced by society today is the use of seaweed seeds whose quality is not good. The availability of seaweed seeds used comes from the production of previous seaweed cultivation which has been used repeatedly, so its growth is slow and it is easily attacked by disease. This results in less than optimal seaweed production. One effort to increase seaweed production is to use quality seeds from tissue culture results.
Based on these problems, a multi-location test of tissue culture seaweed (Eucheuma cottonii ) seeds was carried out on the growth produced by the Ambon Sea Cultivation Fisheries Center in Southeast Maluku and KotaTual districts. This aims to help increase seaweed cultivation production in Southeast Maluku Regency and Tual City.
