RANCANG BANGUN SISTEM OTOMASI LAMPU DAN PENDINGIN SUHU BERBASIS PELTIER MENGGUNAKAN KENDALI PID DENGAN INTEGRASI IOT PADA AQUASCAPE UNTUK OPTIMALISASI PERTUMBUHAN JAVA MOSS

DESIGN AND DEVELOPMENT OF AN AUTOMATED LIGHTING AND TEMPERATURE COOLING SYSTEM BASED ON PELTIER USING PID CONTROL WITH IOT INTEGRATION IN AQUASCAPE FOR OPTIMIZING JAVA MOSS GROWTH

Penelitian ini bertujuan untuk menguji efektivitas sistem kontrol suhu dan pencahayaan otomatis terhadap pertumbuhan Java Moss (Taxiphyllum barbieri) dalam lingkungan Aquascape. Sistem pengaturan suhu dirancang menggunakan kendali PID, di mana parameter awal ditentukan melalui metode Ziegler-Nichols dan disempurnakan dengan fine tuning, menghasilkan nilai akhir Kp  125, Ki  1, dan Kd  700. Sistem ini menjaga suhu air pada nilai setpoint 25 C. Sementara itu, pengaturan pencahayaan otomatis terintegrasi dengan protokol Network Time Protocol (NTP), yang mengaktifkan lampu selama 8 jam per hari guna meniru siklus cahaya alami. Hasil pengamatan menunjukkan bahwa rata-rata pertumbuhan diameter Java Moss mencapai 0,68 cm per minggu dengan variasi antar sampel yang relatif kecil.

This study aims to evaluate the effectiveness of an automated temperature and lighting control system on the growth of Java Moss (Taxiphyllum barbieri) in an aquascape environment. The temperature regulation system was designed using a PID controller, with initial parameters determined by the Ziegler-Nichols method and refined through fine tuning, resulting in final values of Kp 125, Ki 1, and Kd 700. The system maintained the water temperature at a setpoint of 25 C. Meanwhile, the automatic lighting system was integrated with the Network Time Protocol (NTP), activating the light for 8 hours per day to simulate a natural light cycle. Observations showed that the average growth rate of Java Moss reached 0,68 cm per week with relatively small variation among samples.
