Abstract

Hidroponik adalah pengolahan tanaman tanpa tanah atau tempat yang luas. Digunakan sistem nutrient film technique (NFT) untuk hidroponik yang digunakan. NFT merupakan model budidaya hidroponik dengan teknik pemberian nutrisi secara terus menerus yang dialirkan dengan menggunakan pipa dan menggunakan pompa dengan teknik resirkulasi pada tanaman. Di dalam tangki dilakukan proses penetralan pH antara aliran input potassium dyhidrogen phosphate (KH2PO4) dan ammonium nitrate (NH4NO3) pada sistem hidroponik. Melalui tugas akhir ini akan dibuat suatu rancangan sistem pengendalian EC yang menggunakan pengendali fuzzy PID, setelah didapat dari model dinamik nilai nilainya digunakan didalam model statik untuk menentukan nilai pH. Dengan pH yang didapat dimasukkan di neural network jaringan syaraf tiruan untuk mendapat konduktivitas elektrolit (EC), telah dilakukan uji open loop dan close loop. Berawal dari tanpa kontroler menuju PID dan fuzzy PID. Didapatkan nilai parameter PID berupa Kp = 0.1, Ki = 0.01, dan Kd = 0. Didapatkan hasil karakteristik respon yang lebih unggul pada sistem pengendali fuzzy PID, fuzzy PID hampir memiliki semua keunggulan yaitu rise time, settling time yang lebih cepat, overshoot, IAE, dan error steady state yang lebih rendah daripada PID, kecuali untuk settling time pada saat perubahan setpoint 1500µS/Cm. ======================================================================================================================== Hydroponics are plant processing without soil or a wide place. Used nutrient film technique (NFT) system for hydroponics used. NFT is a model of hydroponic cultivation with a continuous nutrition technique that is streamed using pipes and using a pump with recirculation technique in plants. Inside the tank is performed a pH neutrality process between the potassium input flow potassium dyhidrogen phosphate (KH2PO4) and ammonium nitrate (NH4NO3) on the hydroponic system. Through this final assignment, a draft EC control system using fuzzy PID, once obtained from a dynamic model the value of values used in the static model to determine the pH value. With the pH gained in the neural network of neural networks to obtain electrolyte conductivity (EC), after the design of the system is formed, tests of open loop and close loop are conducted. Starting from without a controller to PID and fuzzy PID. Obtained the value of the PID parameter of Kp = 0.1, Ki = 0.01, and Kd = 0. Obtained the result of a superior response characteristics in the fuzzy PID controller system, fuzzy PID almost has all the advantages of the edge of rise Time, faster settling Time, overshoot, IAE, and steady state error lower than PID, except for settling time at change 1500 µS/Cm.
