As part of ongoing research to develop a tool for teaching thermal radiation, we have constructed an Experimental Apparatus of Blackbody Radiation (ARABETA). Some previous researches have been conducted to investigate students understanding of Modern Physics, but very little on the topic of Black-body radiation. Apart from being more abstract, the experimental apparatus on this topic are also almost difficult to find in school laboratories. A preliminary study that involved 53 physics teachers in Jakarta region confirmed that black body radiation is a concept that is difficult to visualize to students during learning. Therefore, we developed a simple apparatus that is capable of measuring the temperature and thermal radiation of the samples used. This research uses research and development model by following some steps of Borg and Gall. The results of this measurement are shown in a graph of intensity against the multiplication result of the Stefan-Boltzmann and the fourth power of its absolute temperature, so that the emissivity value of the sample can be obtained. Through this development, we may provide an alternative solution for the experimentation issue in the learning of blackbody radiation at senior high level.
