Abstract

A water measuring instrument meat can be design using a copper electrode. This measuring instrument has a measuring range of 10 % to 85 %. This series of the instrument includes copper electrode sensor, ADC0804 circuit, AT89S52 microcontroller minimum system circuit and 2x16 character LCD circuit. The response line starts from the electrode sensor circuit of the copper converts the water content of the meat into a voltage, then the voltage is forwarded to the ADC0804 which converts the analog signal into voltage into digital data. The digital data obtained is then sent to the AT89S52 microcontroller to be processed into digital data in the form of digit display and letters on 2x16 character LCD. The display of numbers and letters on the 2x16 LCD shows the measured water content of the meat, the design tool utilizes the characteristics of a copper electrode sensor that produces a voltage change proportional to the change in the water content of the detected meat. Compatibility of design tool with the laboratory method obtained from the result of linear regression analysis of test data that is equal to 99,99%.
