Abstract


Research on Growth Studies Seaweed (Eucheuma cottonii) with Various Different Planting Methods on Kalianda Strait, South Lampung" was done March until April 2010. The aim of this research ware to know and analyze the ratio of floating raft method, long line method, and off-bottom method to growth from Eucheuma cottonii covering as follows : growth rate; growth relative; and weight accretion. The data obtained were analyzed using parametric statistics with more than two different test groups (One Way ANOVA) and continued with LSD test on α = 5% level if data was significantly affected. The results of showed that the floating raft method is more effective than other farming methods. The highest growth rate of Eucheuma cottonii on the floating raft method amounted to 48.40% gr / day. As the same with highest growth relative was found in the floating raft method amounted to 1.569 g and weight accretion of highest on the method of long line of 122.39 gr.

 

Key Words : Seaweed Farming Method, Eucheuma cottonii,

ABSTRAK

Penelitian mengenai Studi Pertumbuhan Rumput Laut (Eucheuma cotonii) dengan berbagai Metode Penanaman yang berbeda di Perairan Kalianda, Lampung Selatan telah dilaksanakan pada bulan Maret sampai April 2010. Tujuan penelitian ini adalah mengetahui dan menganalisis perbandingan metode budidaya rakit apung (floating raft method), rawai panjang (long line method), dan lepas dasar (off-bottom method) terhadap pertumbuhan Eucheuma cottonii melalui pengukuran : laju pertumbuhan; pertumbuhan nisbi/relatif, dan pertambahan berat. Data yang diperoleh dianalisis menggunakan statistik parametrik dengan uji beda lebih dari dua kelompok (One Way Anova) dan apabila berpengaruh nyata maka diuji lanjut dengan uji LSD pada taraf α = 5%. Hasil penelitian yang diperoleh menunjukkan bahwa metode budidaya rakit apung lebih efektif dibanding dengan metode budidaya lainnya. Laju pertumbuhan tertinggi  Eucheuma cottonii didapatkan pada metode rakit apung sebesar 48,40 %gr/hari. Pertumbuhan nisbi/relatif tertinggi didapatkan pada metode rakit apung sebesar 1,569 gr dan pertambahan berat tertinggi didapatkan pada metode long line sebesar 122,39 gr.
