Study of rice humidity has been made to prototype an instrument that can input fisis parameter like humidity to voltage. Rice variety has been researched such as Anak Daro, BB 42 and Sokan. The measurement of humidity level according to oscillator LC output voltage for humidity level researched for 13% until 26%. Oscilator output voltage had the most value for Sokan variety was 1887.8 mV by hum…
