The function of vibration is to smooth the flow of hot air into the Refuse Derived Fuel (RDF) which is put on the drying trays, so during drying process the door of drying chamber are not necessarily to be opened. The vibration components are placed just below the drying trays and consist of electrical motor, spring, total mass and unbalance mass which is connected to the motor shaft. RDF Dryer machine in this research would not take heat energy from coal fuel but from dried RDF fuel through shell and tube heat exchanger. Beside that, the research would not take electrical energy from government company but from micro hydro power plant. The objective of this research is to perform analysis and innovation on RDF dryer machine. This research uses observation, analysis and innovation methods and the material tested in the drying chamber was RDF. The total length of the RDF dryer machine is 5.8 m and its drying chamber has a dimension of: Length 4 m, Width 3 m, and Height 2 m. Based on the analysis and innovation result the optimal motion of the samples being dried occurred at angular speed near its natural frequency. Analysis heat Transfer was obtained that the average air temperature in the drying chamber could be achieved by the utilization of shell and tube heat exchanger. Shell and tube heat exchanger was made of aluminium material with a thickness of each material of 0.001 m. Analysis electrical energy was obtained that electrical power output more than required electrical energy by RDF dryer machine.
