Abstract


Research of Growth Rate of Gracilaria sp. by Multilevel Racks Method at Kalianda Waters, South Lampung was held at May until June 2010. The aim of this research were to know and analyze comparative growth of Gracilaria sp. by multilevel racks method consisting of 5 levels with different depth of each level, through measurement : average of weight gain, growth rate, and growth relative. Data was analyzed by using ANOVA (Tukey test) to assess whether the average of the five levels statistically different each other. The highest Gracilaria sp. comparative growth in 6 weeks period on research was available at first level with 30,2 gr/week. The highest growth rate was available at first level with 4,25 %gr/day. The highest growth relative was available at first level with 1,86 gr. The result of research showed that level 1 and level 2 (depth of 30 cm and 60 cm) was the effective growth rate level than the others.

 

Keywords : Multilevel Racks Method, Gracilaria sp., Kalianda.

 

ABSTRAK

Penelitian mengenai Laju Pertumbuhan Rumput Laut Gracilaria sp. dengan Metode Rak Bertingkat di Perairan Kalianda-Lampung Selatan telah dilaksanakan pada bulan Mei sampai Juni 2010. Tujuan penelitian ini adalah mengetahui dan menganalisis perbandingan pertumbuhan Gracilaria sp. dengan metode penanaman rak bertingkat yang terdiri dari 5 tingkatan dengan perbedaan kedalaman tiap tingkatannya, melalui pengukuran : rata-rata pertambahan berat, laju pertumbuhan, dan pertumbuhan nisbi/relatif. Data yang diperoleh dianalisis menggunakan ANOVA (Uji Tukey) untuk menilai apakah rata-rata kelima tingkatan secara statistik berbeda satu sama lain. Pertambahan berat rata-rata tertinggi rumput laut Gracilaria sp. dalam periode 6 minggu pengamatan didapatkan pada tingkat I sebesar 30,2 gr/minggu. Laju pertumbuhan tertinggi didapatkan pada tingkat I sebesar 4,25 %gr/hari. Pertumbuhan nisbi/relatif tertinggi didapatkan pada tingkat I sebesar 1,86 gr. Hasil penelitian yang diperoleh menunjukkan bahwa tingkatan I dan II (kedalaman 30 dan 60 cm) merupakan tingkatan yang paling efektif tingkat laju pertumbuhannya dibandingkan dengan tingkatan dibawahnya.
