Pemanfaatan Load Cell CZL601 untuk Pengukuran Derajat Layu Pada Pengolahan Teh Hitam

Abstract

This paper describes result of research about measurement of degree of wilting in black tea processing. Degree of wilting was observed by measuring of tea leaves mass loss because the loss of water content. Mass sensor used is single point load cell type CZL 601 that can measure up to 20 kg. Results of calibration of load cell gives the characteristic equation V = 0.0001 m + 0.2014 volts. Output of sensor is connected with instrumentation amplifier which with applying three IC OP-07 which subsequently became data process for mirokontroller ATMega8. Data measurement result interfaced on the LCD. Instrumentation system was implemented in mini process factory at Indonesian Research for Tea and Cinchona Gambung, Bandung. Results of measurement of mass loss in a trough of 48.39%, whereas in the sample basket was 49.33%. Measuring the degree of wilting during the withering of the production process is 37.00%.
