PERTUMBUHAN RUMPUT LAUT KAPPAPHYCUS ALVAREZII YANG DIBUDIDAYAKAN BERSAMA EUCHEUMA DENTICULATUM DENGAN KOMPOSISI BERBEDA
ABSTRACT: The objective of
this study was to determine the growth of seaweed Kappaphycus alvarezii
cultivated with Eucheuma denticulatum with different composition. This research
was carried out for six weeks, from March to April 2013, in the coastal waters
of Sondaken village, Tatapaan District, South Minahasa regency, North Sulawesi.
The experiment was designed according to completely randomized design with four
treatments and three replications. The four tested treatments were the
different composistion of tied seaweed in a long-line raft, where treatment A:
100% K. alvarezii, ; B: 50% K. alvarezii and 50% E. denticulatum, on each
culture line, two types of algae were tied in sequence; C: 75% K. alvarezii and
25% E. denticulatum, in which in each line, every three bunch of K. alvarezii
was followed by one bunch of E. denticulatum; D: 25% of K. alvarezii and 75% E.
denticulatum, on each culture line, every three bunch of E. denticulatum was
followed by one bunch of K. alvarezii. Each experimental unit was a 3m x 3,4m
rectangular line raft containing four culture lines where the bunch of the
tested seaweed were tied. Data collection was performed every two weeks by
weighing the tested K alvarezii. The data were statistically analyzed (ANOVA)
using JMP statistical program (SAS-institute). The results showed that absolut
growth, relative growth and daily growth rate of K. alvarezii was not
significantly affected by the tested treatments (Prob> F > 0.5). Thus,
the occurence of E. denticulatum in whatever abundance in K. alvarezii
cultivation area will not affect the growth of K. alvarezii.
