Abstract: Kegiatan pemantauan kualitas air limbah merupakan bagian penting dalam upaya menjaga kelestarian lingkungan dan memastikan air buangan memenuhi baku mutu sebelum dilepaskan ke badan air penerima. Penelitian ini bertujuan untuk merancang dan menguji prototipe sistem pemantauan kualitas air limbah berbasis Internet of Things (IoT) dengan parameter utama pH, suhu, dan Total Dissolved Solids (TDS). Sistem dirancang menggunakan mikrokontroler Arduino Nano dan ESP8266 yang berfungsi untuk membaca data sensor, menampilkan hasil pengukuran pada layar LCD, serta mengirimkan data secara real-time ke Firebase Realtime Database. Hasil pengujian menunjukkan bahwa sensor DS18B20 dan pH-4502C memiliki tingkat akurasi di atas 94%, sedangkan sensor Gravity TDS DFRobot menunjukkan akurasi rata-rata sebesar 65%. Sistem yang dikembangkan mampu menampilkan data secara daring dan real-time sehingga dapat mendukung proses pemantauan kualitas air limbah secara lebih efisien dan berkelanjutan.
Monitoring wastewater quality is an essential effort to ensure environmental sustainability and compliance with discharge standards before the effluent enters receiving waters. This study aims to design and evaluate an Internet of Things (IoT)-based prototype for monitoring wastewater quality using three main parameters: pH, temperature, and Total Dissolved Solids (TDS). The system employs Arduino Nano and ESP8266 microcontrollers to collect sensor data, display measurements on an LCD, and transmit data in real time to the Firebase Realtime Database. The experimental results indicate that the DS18B20 temperature sensor and pH-4502C sensor achieved accuracy levels above 94%, while the Gravity TDS DFRobot sensor obtained an average accuracy of 65%. The developed system successfully provides online and real-time data visualization, supporting a more efficient and sustainable wastewater quality monitoring process.
