Abstract
Pengendalihan pH pada sistem hidroponik sangat diperlukan karena untuk mengoptimalkan penyerapan nutrisi oleh tanaman. Pada plant hidroponik kali ini nutrisi yang digunakan adalah AB Mix. Penambahan AB Mix akan mempegaruhi perubahan nilai pH. Tanaman yang digunakan adalah tanaman kangkung yang memiliki set point pH sebesar 6,5. PID dan JST merupakan jenis kontrol yang dapat digunakan untuk mengendalikan pH pada plant hidroponik. Kontrol JST menggunakan Model Reference Neural Network Controller. Algoritma yang digunakan adalah algoritma Levenberg-Marquardt. Nilai kp, ti, dan td pada pengendali PID secara berurutan sebesar 7,45; 2,8; 0,725. Pada kontrol PID didapatkan nilai maximum overshoot sebesar 49,5 %, settling time 20 detik, error steady state 0,5 %, dan IAE 5063. Sedangkan pada kontrol JST didapatkan nilai maximum overshoot sebesar 0,3 %, settling time 20 detik, dan error steady state 0,35 %, dan IAE 4828. Kontrol terbaik yang digunakan pada plant hidroponik adalah kontrol JST.

Reducing the pH of the hydroponic system is needed because it optimizes the absorption of nutrients by plants. In this hydroponic plant, the nutrient used is AB Mix. The addition of AB Mix will affect changes in pH. The plants used are spinach plants that have a pH set point of 6.5. PID and ANN are control types that can be used to control pH in hydroponic plants. ANN control uses the Neural Network Controller Model Reference. The algorithm used is the Levenberg-Marquardt algorithm. Value kp, ti, and td in control PID is 7.45; 2.8; 0.725. In the PID control the maximum overshoot value is 49.5 %, the setting time is 20 seconds, error steady state is 0.5 %, IAE 5063. Whereas in the ANN control, the maximum overshoot value was 0.3 %, the settling time was 20 seconds, error steady state was 0.35%, and IAE 4828. The best control used in hydroponic plants is ANN control.
