PENGARUH PERBEDAAN VARIETAS RUMPUT LAUT (Kappaphycus sp) DAN VARIASI KEDALAMAN TERHADAP PERTUMBUHAN DAN PRODUKSI RUMPUT LAUT MENGGUNAKAN METODE BUDIDAYA “Top Down”
ABSTRACT: The objective of
this study was to investigate the effect of different types of Seaweed (Kappaphycus
sp) and depth variation on the growth, production and carrageenan content of
Seaweed using a top down cultivation method. Top down method combined the two
methods of cultivation, the method of surface and off-bottom method. The types
of Seaweed used were Kappaphycus alvarezii (Brown Maumere and Local Maumere)
and Bali Seaweed (Kappaphycus striatum). This study was designed using a
factorial experimental design, where is comprised of two factors: the types and
water depth. Parameters measured were daily growth rate, production and
carrageenan content of Seaweeds. The results showed that different types of
Seaweed gave a significant effect (P<0.05) on daily growth rate and
production of Seaweeds, however depth variation did not give a significant effect
on daily growth rate and production of Seaweeds (P>0.05). A combination of
Seaweed types and depth variation did not give a significant effect on daily
growth rate and production of Seaweeds (P>0.05). The highest carrageenan
content was found in Local Seaweed (42.15%). Brown Seaweed produced 40.59% of carrageenan
content while Bali Seaweed produced 35.80%.
