Uji Performansi Alat Pengering Tipe Terowongan Hohenheim Aceh Dengan Aplikasi Proportional Integral Derivative Controller Untuk Kipas Outlet

The purpose of this study was to evaluate the performance Hohenheim Aceh type solar tunnel dryer with application proportional integral derivative (PID) controller for outlet fans . instrumentations used were Aceh, HTC-meter, anemometer, pyranometer, and other supporting equipment s results showed that during drying process irradiation had fluctuat ed , where average 649 W/m 2 temperature in chamber is 40.6°C while environment 32.9°C. Conditions suitable because inside relatively higher than ambient temperature. relative humidity ( RH ) 36% about 40% T he relationship between value negative strong indicated bu r-value 0.7379 On hand, t positive also indicating energy source from an R -square 86.02 % 0.92747 PID improved by preventing incident unproper However, airflow too low thus further engineering design needed improve system.
