Abstract

Telah dilakukan pengukuran radiasi panas pada RHT Apparatus dengan dan tanpa menggunakan bahan absorber. Tujuan penelitian ini adalah mengetahui perbedaan waktu pemanasan dan pendinginan dengan menggunakan bahan absorber, mengetahui pengaruh jarak heater terhadap jumlah fluks panas yang diterima oleh radiometer, mengetahui pengaruh panas temperatur heater terhadap jumlah fluks panas yang diterima oleh radiometer, mengetahui nilai error fluks panas yang terjadi antara pengukuran radiometer dan termokopel, serta mengetahui nilai emisivitas pada bahan absorber. Pada proses pemanasan dan pendinginan heater antara temperatur 34 ⁰C – 200 ⁰C, terdapat perbedaan waktu cukup jauh yang mana pemanasan heater membutuhkan waktu 25 menit dan pendinginan heater membutuhkan waktu 5 jam 36 menit. Pada pengujian pengaruh jarak sensor, diperoleh bahwa besar jarak berbanding terbalik terhadap jumlah fluks panas. Sedangkan pada pengujian pengaruh temperatur heater, diperoleh bahwa temperatur heater berbanding lurus dengan fluks panas. Nilai keseksamaan diperoleh sebesar 0,9886 pada jarak 30 cm; 0,9798 pada jarak 32,5 cm; 0,9672 pada jarak 35 cm; 0,9767 pada jarak 37,5 cm; 0,9486 pada jarak 40 cm. Nilai emisivitas bahan uji sampel aluminium seng yang diperoleh dari penelitian yaitu sebesar 0,17

Measurements of heat radiation have been carried out on the RHT Apparatus with and without the use of absorber materials. The purpose of this study was to determine the difference in heating and cooling time using absorber materials, to determine the effect of heater distance on the amount of heat flux received by the radiometer, to determine the effect of heater temperature on the amount of heat flux received by the radiometer, to determine the error value of heat flux that occurs between radiometer and thermocouple measurements, as well as knowing the emissivity value of the absorber material. In the heating and cooling process of the heater between temperatures of 34 C - 200 C, there is a considerable time difference where heating the heater takes 25 minutes and cooling the heater takes 5 hours 36 minutes. In testing the effect of sensor distance, it is found that the distance is inversely proportional to the amount of heat flux. Meanwhile, in testing the effect of heater temperature, it is found that the heater temperature is directly proportional to the heat flux. The accuracy value is 0.9886 at a distance of 30 cm; 0.9798 at a distance of 32.5 cm; 0.9672 at a distance of 35 cm; 0.9767 at a distance of 37.5 cm; 0.9486 at a distance of 40 cm. The emissivity value of the aluminum zinc sample test material obtained from the research is 0.17.
