The project is subject to degradation by fermented rice stubble. With the aim to compare the performance of water hyacinth and banana suckers from fermentation to decompose rice stubble. The steps used in the operation, including 1) the process of making fermented. The formula used by the Department of Lands 2) Convention on the experiment to test the second step is to test the sub-physical. Stubble to test the water to ferment and then use a spring scale to test the durability of the fiber, rice stubble. And biological tests By the stubble grain drying at 80 degrees Celsius. Then assayed by reducing sugar. Somogyi-Nelson (Nelson, 1944) to determine the activity of the enzyme cellulase. The results conclude that the EM hyacinth effective in degrading Stubble better from fermented banana shoots.
