Penggunaan Pupuk Conway Pada Media Kultur Terhadap Pertumbuhan Bibit Rumput Laut Eucheuma cottonii
Rumput laut jenis Eucheuma cottonii adalah salah satu hasil perikanan yang mempunyai nilai ekonomis cukup penting karena mengandung karagenan yang merupakan bahan dasar dalam industri farmasi, makanan, maupun bahan industri lain. Mengingat besarnya permintaan pasar akan kebutuhan rumput laut maka perlu dilakukan usaha untuk meningkatkan produksinya. Namun seiring dengan meningkatnya permintaan, pembudidaya sering mengalami permasalahan antara lain bibit rumput laut yang dihasilkan belum maskimal baik dari segi jumlah maupun kualitas, sehingga perlu ada kajian untuk menghasilkan pertumbuhan benih bibit rumput laut yang baik yaitu menggunakan pupuk Conway pada media kultur rumput laut dari hasil kultur jaringan.

期刊介绍:
The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
