This research is a study on the production of insulation from coconut fiber and para rubber. Four from compared to foam. The plates used with 15x15x1.5cm. Inside the model was divided for the experiment box with 15x15x15cm. By using spotlights as a heat source.
The results show that at 90 and 60 cm. Insulation para rubber on one side increase temperature of 1.7 and 1.2 oC from 25.2 oC, at 30 cm. Insulation coconut fiber increase temperature of 2.6 oC from 25.4 oC.
