PERTUMBUHAN RUMPUT LAUT KAPPAPHYCUS ALVAREZII YANG DIKULTUR MENGGUNAKAN DUA JENIS TALI RIS DENGAN KONDISI BERBEDA
ABSTRACT: The study aimed to
determine the growth of seaweed Kappaphycus alvarezii cultured using different
type of rope ris with different conditions. The study was conducted over 64
days, starting on September 1 to November 3, 2014 Village Jaya Karsa, North
Minahasa Regency, North Sulawesi. The experiment was designed according to 2x3
factorial experiment in a completely randomized design (CRD). Two factors were
tested, namely rope ris type and conditions. Factors ris types strap consisted
of two type: Monofilament nylon and Multifilament PE. Factor conditions of ris
rope consisted of three levels, namely: new, used cleaned, and the former was
not cleaned, so there were 6 treatments. Experiment container was floating
longlines. One unit consisted of 3 longline trial. Length per longline 28.80 m,
18 pieces of string length of rope ris 1.6 m each strap was 7 point planting,
planting the overall number of points 378 points planting. K. alvarezii seaweed
seedlings obtained from Jaya Karsa farmers. Weighing was done 4 times, weighing
early, 1 week, 2 weeks, and at the end of week 3, using a digital scale with a
precision of 1 g. Accretion weight was calculated to be the absolute growth
rate (g) and daily growth rate (%). The results showed that the absolute growth
and the daily growth of seaweed K. alvarezii not significantly influenced by
different type and condition of the rope ris.
