Abstract
Peningkatan suhu lingkungan akibat perubahan iklim berdampak signifikan terhadap kualitas air, terutama dalam sistem pertanian hidroponik yang memerlukan suhu air rendah untuk mendukung pertumbuhan tanaman secara optimal. Penelitian ini bertujuan untuk merancang dan membuat sistem pendingin air menggunakan Thermoelectric Cooler (TEC) tipe TEC1-12706, yang memanfaatkan prinsip efek Peltier sebagai solusi ramah lingkungan untuk menurunkan suhu air secara efisien. Sistem terdiri dari enam unit TEC yang dikendalikan oleh mikrokontroler Arduino Uno, dilengkapi sensor suhu DS18B20 dan LCD I2C sebagai tampilan suhu. Pendinginan dilakukan dalam wadah aluminium berkapasitas 10 liter tanpa insulasi tambahan. Pengendalian daya menggunakan teknik Pulse Width Modulation (PWM) berbasis Arduino, memungkinkan penyesuaian dinamis sesuai suhu aktual. Hasil pengujian menunjukkan penurunan suhu dari 28,1°C menjadi 18,6°C dalam 300 menit, dengan konsumsi daya total sebesar 432 Watt. Evaluasi menggunakan Coefficient of Performance (COP) mengindikasikan bahwa penambahan jumlah TEC meningkatkan kemampuan pendinginan meski menurunkan efisiensi energi. Sistem ini bekerja secara otomatis dan menunjukkan potensi sebagai solusi portabel, efisien, dan ramah lingkungan, tidak hanya untuk hidroponik, maupun aplikasi pendinginan air di bidang pertanian modern lainnya.

The increase in environmental temperatures due to climate change has a significant impact on water quality, particularly in hydroponic farming systems that require low water temperatures to support optimal plant growth. This study aims to design and develop a water cooling system using a Thermoelectric Cooler (TEC) type TEC1-12706, which utilizes the Peltier effect principle as an environmentally friendly solution to efficiently lower water temperatures. The system comprises six TEC units controlled by an Arduino Uno microcontroller, equipped with a DS18B20 temperature sensor and an I2C LCD display to monitor water temperature. Cooling is carried out in a 10-liter aluminum container without additional insulation. Power control is managed using Pulse Width Modulation (PWM) techniques based on the Arduino, allowing dynamic adjustment according to the actual temperature. Test results showed a temperature drop from 28.1°C to 18.6°C within 300 minutes, with a total power consumption of 432 Watts. Evaluation using the Coefficient of Performance (COP) indicates that increasing the number of TEC units enhances the cooling capacity, although it decreases energy efficiency. The system operates automatically and demonstrates potential as a portable, efficient, and environmentally friendly solution—not only for hydroponics but also for water cooling applications in other areas of modern agriculture.
