Materials and Research Methods Experimental Materials.
The materials such as rice husk, rice straw, water hyacinth, cassava peels were used in the research.
These materials were pre-treated before the experiment.
Finally, they were sieved, and materials were sized approximately 0.154mm.
Comparing germination rate of fertilizer with the land of various materials.

Materials and Methods Granite Varieties.
Given the large number of parameters that can affect cutting and the complexity of the problem, we tested the materials by varying only those parameters which most affect the cut: linear cutting speed (m/min) and cutting depth (mm).
