Abstract

This study aims to describe the knowledge of physics teachers about the management of physics laboratories in SMP and SMA Negeri Bengkulu City. This ex-post facto descriptive study used a sample taken with a total sampling method to all physics teachers in SMP and SMA Negeri Bengkulu City. Data were collected using test instruments. The results of this study indicate that the junior high school physics teacher's knowledge about laboratory management is in the sufficient category indicated by the frequency of 35 respondents (64.8%) and the high school physics teacher's knowledge about laboratory management is also in the sufficient category indicated by the frequency of 22 respondents (84.6%). ). Knowledge based on teaching status, either not certified or certified or knowledge based on teaching experience, is in the sufficient category. Meanwhile, knowledge based on the aspects of factual knowledge, conceptual knowledge, procedural knowledge, and metacognition knowledge, the majority of respondents were in the sufficient category. The conclusion from this research is that the knowledge of physics teachers about physics laboratory management in SMP and SMA Negeri Bengkulu city is sufficient.

Abstract

This study using a cuboidal space miniature aims to determine the emissivity values ​​of purple, green, and blue colors. By carrying out eight actions to change the power of the lamp, starting from incandescent lamps of 5 watts, 25 watts, 60 watts, 75 watts, 100 watts and 5 watts, 20 watts, and 25 watts of white TL lamps. Emissivity value can be calculated by comparing the value of the resistance of each color to the value of black resistance. The results show that the emissivity value of purple (purple comet) is 0.91, emissivity of green (going green) is 0.84, and emissivity of blue (true) blue) of 0.77.
