Abstract

The objective of this study was to determine the use of tapioca flour as a heat insulator for learning media for students with hearing impairments. Experiments were done method by testing tapioca flour placed on the wall that heat radiated by bulb lamp with various intensities (i.e. 8, 10, and 12 W). The results showed that tapioca flour is a good heat insulator. This is confirmed by the test results using thermocouple tools showing a decrease in temperature of the insulator testing toolbox. The tapioca flour caused the heat from the lamp inside the box to be restrained from spreading out completely. The concept of heat radiation and the change of heat adsorbed by tapioca flour was explained, which can be further developed for learning media for students with hearing impairment. The results of this study are expected to facilitate teachers in providing understanding to students in understanding the occurrence of heat insulators, especially for students with hearing impairments.
