Abstract: Heat transfer is a
science to determine heat transfer occurs in certain conditions due to
temperature differences. The thermal conductivity is the nature of the form
termofisik transport properties for heat transfer. Thermal conductivity value
indicates how quickly heat mangalir in that particular material and understand
the phenomena that occur in the conduction heat transfer. In this study focused
on the value of the thermal conductivity of composite particles robusta coffee
with a variety of mesh sizes 20, 40, 60, 80 and 100. The method of making
composite using hand lay up. Variables used include variations in particle size
coffee mesh 20, 40, 60, 80 and 100. The tests performed by the method of
thermal conductivity in the composite particles of coffee. Data collection was
performed by the method of observation for 60 minutes. From the research
results minimum composite thermal conductivity values on the particle size of
coffee that passes sieve mesh 20 that is equal to 0.006 W / mᵒC, composite
thermal conductivity values optimum particle size of the coffee that passes
sieve mesh 60 that is equal to 0.013 W / mᵒC. While the value of thermal
conductivity composites in the coffee particle size that passes a sieve mesh of
100 decrease in the amount of 0.008 W / mᵒC. From the data analysis, it can be
concluded that the smaller the particle size of the coffee, the thermal
conductivity decreases indicating increased ability to inhibit heat conduction.
