It has been realized an instrument for measuring cassava starch content digitally based on specific gravity method. The instrument is designed using strain gauge, which packing in load cell as a mass sensor, HX711 (Analog to Digital Converter), Arduino Uno as a data processor, LCD, and personal computer. The principles of this instrument are using specific gravity method, which is based on differences of cassava mass in the air and the water. Cassava starch content calculated by Arduino using Sungzikaw equation and displayed in LCD screen. The result showed that the instrument capable measure cassava starch content with the maximum capacity of 2,0 kg and average percentage error of less than 1,5 %.
