Pertumbuhan rumput laut Kappaphycus alvarezii pada perbedaan kedalaman dan berat awal di perairan Talengen Kabupaten Kepulauan Sangihe
ABSTRACT: The effect of depth
and weight differences on early stage of seaweed growth Kappaphycus alvarezi
was studied. This Research was conducted for over 42 days, from April to May
2013 in Talengen Waters, Regency Sangihe Islands, North Sulawesi. Experiment
designed used was 4 x 3 factorial experiment in a completely randomized design,
so there were two factors namely depth and weight. The depth factor (D)
consisted of four levels and initial weight (W) consisted of three levels, thus
there were 12 treatment combination: D1W1 (25 cm, 75 g), D1W2 (25 cm, 100 g),
D1W3 (25 cm, 125 g), D2W1 (75 cm, 75 g), D2W2 (75 cm, 100 g), D2W3 (75 cm, 125
g), D3W1 (125 cm, 75 g), D3W2 (125 cm, 100 g), D3W3 ( 125 cm, 125 g), D4W1 (175
cm, 75 g), D4W2 (175 cm, 100 g), and D4W3 (175 cm, 125 g). Data collected were
analyzed statistically using the statistical program JMP (SAS Institute).
Statistical analysis showed there was a significant differences in relative
growth of seaweed K. alvarezii (P> F.0003 <.01).The best relative growth
of seaweed K. alvarezzi was achieved in treatment combination D1W1 (25 cm, 75
gr) as much as 302.89%.
