Perbedaan Pertumbuhan Rumput Laut Kappaphycus alvarezii Terhadap Jarak Tanam

Rumput laut merupakan salah satu komoditas ekonomi yang menjadi unggulan Indonesia dan jenis banyak dibudidayakan adalah Eucheuma cottonii (Kappaphycus alvarezii) spinosum. Usaha peningkatan produksinya dikembangkan melalui modifikasi metode budidaya untuk mencapai hasil produksi maksimal. Jarak tanam faktor berpengaruh terhadap pertumbuhan produksi. Penelitian ini bertujuan menguji perbedaan jarak laju rumput K. alvarezii. Metode penelitian digunakan kuantitatif dengan perlakuan berupa tanam. Rancangan percobaan Acak Lengkap 3 (20 cm, 30 40 cm) masing-masing tiga ulangan. Parameter diamati yaitu spesifik mingguan, mutlak kelulushidupan Hasil menunjukkan berbeda serta terdapat nyata dari tiap waktu ke waktu. analisa statistik pada setiap pengukuran. memberikan terbaik cm berat rata-rata 545,9 gr 3,84% per hari. Seaweed is one of Indonesia’s leading economic commodities. The species that are widely cultivated in Indonesian waters and Efforts to increase production developed through modification cultivation methods achieve maximum results. Plant spacing the factors affect growth increased relation nutrient absorption because will movement water carryiing nutrients. This study aims examine differences plant on optimal rate alvarezii seaweed for research method used a quantitative with treatment form spacing. experimental design was completely randomized using treatments replications. Parameters observed were weekly specific rate, absolute survival results showed different had an effect there significant each from time time. statistical analysis measurement gave best found by producing average weight gain g day.
