Pertumbuhan rumput laut Kappaphycus alvarezii hasil kultur jaringan pada jarak tanam yang berbeda
Abstract
Abstract. The purpose of this study is to wede168 determine the best planting space on the growth of regenerated tissue culture Kappaphycusalvarezii. The completely randomized design (CRD) was utilized in this study, thre treatment was four different planting spaces; P1: 15cm, P2: 20 cm, P3: 25 cm, and P4: 30 cm with initial weight of 100g/hill. Every treatment has four replicates (four rafts). The data were subjected to one way of analysis of variance (ANOVA) at 5% of error levels and followed by Least Significant Difference (LSD) test. The Anova test showed that planting space gave a significant affect on weight gain and growth rate where the best planting space was 25 cm with weight gain and growth rate of 331.4 g and 4.87% perday, respectively.

Abstrak. Tujuan penelitian ini adalah untuk menentukan jarak tanam optimum untuk pertumbuhan rumput laut Kappaphycus alvarezii hasil kultur jaringan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan menggunakan bibit hasil kultur jaringan dengan jarak tanam yang berbeda yakni P1: jarak tanam 15cm , P2: jarak tanam 20 cm, P3: jarak tanam 25 cm, dan P4: jarak tanam 30 cm dengan berat awal 100 g/rumpun, masing-masing perlakuan dengan empat kali ulangan pada 4 rakit. Data penelitian yang diperoleh, ditabulasi menggunakan Microsoft excel dan dianalisis menggunakan analisis sidik ragam (ANOVA) pada taraf kesalahan 5%, kemudian dilakukan uji lanjut dengan uji Least Significant Difference (LSD). Hasil penelitian ini menunjukkan bahwa jarak tanam berpengaruh nyata terhadap pertumbuhan rumput laut (P<0,05), dimana jarak tanam terbaik adalah 25 cm dengan pertambahan bobot 331,4 g dan laju pertumbuhan 4,87% per hari.
