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}, journal = {American Journal of Animal and Veterinary Sciences}, publisher = {Science Publications} }
