Malaysia is a one of tropical forest country in the Southeast Asia and they have a great potential of green agriculture source to be used as a renewable energy. One of this source is a Kenaf that is consist of a core and bast fibers. In this study, biomass which is Kenaf plant was dried using Sherwood M501 air fluid bed dryer. Air fluid bed dryer is one of the fluidization drying process that have potential to be widely used. The current properties in this material used contain the high value of water when produced pellet. Therefore, a study was conducted to determine the characteristics and the percentage of Kenaf focused on moisture loss of Kenaf sample via fluidization drying process. The results of found that during fluidization process the best condition that reduce most of the moisture content of sample is the second condition that applied 4.0 m/s velocity (50% of fan speed), 46°C temperature. Effect of the used of suitable amount of air velocity and temperature would attributed to the physical characteristics change and moisture content value that should be obtained.
