Abstract The quantity and quality of carrageenan produced is influenced by the method extraction solvent. Characterization products necessary to get certain standards so product acceptable consumers both locally internationally. purpose this research was determine solvents that can produce from Kappaphycus alvarezii with best characteristics compare results international in order obtain a stand...

Integrated marine aquaculture or known as Multi-Tropical Aquaculture (IMTA) is an alternative development in activities under the concept of environmental conservation. There are several important aspects supporting success seaweed cultivation including use right weight seeds at beginning activities. The purpose this study was to analyze effect seedling on growth Kappaphycus Alvarezii cultivate...

In this research work, MgO nanoparticles were synthesized by a single-step coprecipitation approach using Kappaphycus alvarezii extract as stabilizer. The exhibit cubic crystal structure, which confirmed XRD and FTIR. purity of nanomaterials was P-XRD. diffraction crests are in accordance with customary patterns pure (JCPDS No.00–004-0821). Electron microscopic analysis demonstrated the appeara...
