Abstract
Telah dilakukan perancangan plant pengendalian pH pada tanaman Pakcoy sistem hidroponik NFT dengan metode fuzzy-PID. Pemodelan pH dilakukan dengan metode reaksi invariant yang terdiri dari pemodelan statik dan dinamik. Pemodelan dinamik memperoleh nilai konsentrasi yang kemudian nilai tersebut digunakan pada pemodelan statik untuk memperoleh nilai pH. Setelah dilakukan pemodelan kemudian dilanjutkan dengan pengendalian nilai pH agar tetap berada di sekitar nilai setpoint dengan sistem kontrol metode fuzzy-PID. Masukan pada kontrol logika fuzzy berupa nilai error dan keuaran berupa nilai Kp yang kemudian akan menjadi masukan pada sistem kontrol PID dengan parameter lainnya yaitu Ki sebesar 0,015 dan Kd yang bernilai 0,025. Karakteristik respon kontroler yang di tuning dengan fuzzy-PID adalah rise time sebesar 0.0554 detik, settling time sebesar 76.59 detik, overshoot sebesar 30.73% , peak time sebesar 4.57 detik, serta error steady state sebesar 0.0228%.
=========================================================
A pH control plant has been designed on the Pakcoy NFT hydroponic system using the fuzzy-PID method. pH modeling is done by invariant reaction methods which consist of static and dynamic modeling. Dynamic modeling obtains concentration values which are then used in static modeling to obtain pH values. After modeling it is then continued with controlling the pH value so that it stays around the setpoint value with the control system fuzzy-PID method. Input to fuzzy logic control in the form of error value and output in the form of Kp value which will then be input to the PID control system with other parameters namely Ki of 0.015 and Kd of 0.025 value. The response characteristics of the controller tuned with fuzzzy-PID are rise time of 0.0554 seconds, settling time of 76.59 seconds, overshoot of 30.73%, peak time of 4.57 seconds, and error steady state of 0.0228%.
