Abstract

The principle of ultrasonic waves in detecting materials is based on their physical properties. The size of particles has an impact on various aspects of their composition and function. The limited information that reports the particle size of RH-contaminated RB samples tested using ultrasonic waves is the basis for this study. This study aims to determine the optimal sample particle size for testing RB contaminated with RHs in order to obtain the most accurate and consistent results when reading with ultrasonic waves based on attenuation. The research method used Completely Factorial Random Design (CFRD) with factor levels of RH (0, 20, 40, 60, 80, and 100%) and different particle sizes (10, 20, 30, 40, and 50 mesh). The test principle is to transmit ultrasonic waves with a frequency of 50 kHz through the sample. The results of statistical analysis showed that the RH level was very real (p<0.01) affecting the damping and speed. The higher the RH content, the higher the damping value. The particle size of RB is very real (p<0.01) affects the attenuation and velocity, the smaller the particle size, the higher the damping value. Conclusion of this study are the level of RHs and the particle size of the sample affect the accuracy of ultrasonic wave readings on RB contaminated with RHs. The optimal particle size for testing RB contaminated with RHs using ultrasonic waves with attenuation parameters is mesh 30, resulting in a linear regression pattern with a 91.30% r-square value. More research needs to be done on these results to find out what affects the transmission (amplitude) of ultrasonic waves when measuring samples.
