What is ARTIKEL EKSTRAKSI KARAGENAN Abstrak Inggris about?
The document compares carrageenan extraction from seaweed using conventional and ultrasonic wave methods. Conventional extraction at 90°C for 3 hours with a seaweed to solvent ratio of 1:40 produced a 65% yield. Ultrasonic wave extraction at 50°C for 40 minutes with a 1:30 ratio produced a similar 65.79% yield, showing it is more efficient by requiring lower temperature, less solvent, and less time. Both methods produced carrageenan samples with similar quality parameters. FTIR testing confirmed the seaweed
