Abstract

Kualitas udara di kawasan Bundaran Pintu Masuk Institut Teknologi Sepuluh Nopember (ITS) belum dimonitoring secara real-time, padahal aktivitas kendaraan bermotor berpotensi meningkatkan konsentrasi polutan udara berupa karbon monoksida (CO) dan partikulat halus (PM2.5) yang berdampak terhadap kesehatan dan kualitas lingkungan kampus. Oleh karena itu, pada penelitian ini dirancang dan dibangun sistem monitoring kualitas udara portable berbasis Internet of Things (IoT) untuk memantau konsentrasi CO dan PM2.5. Sistem menggunakan mikrokontroler ESP32-S3, sensor PMS7003 sebagai sensor PM2.5, dan sensor MiCS-5524 sebagai sensor CO. Data hasil pengukuran ditampilkan pada LCD serta dikirimkan ke server berbasis web untuk disimpan ke dalam database dan divisualisasikan melalui dashboard secara real-time. Dashboard telah di-hosting dan dapat diakses melalui domain itsairsense.com. Hasil pengujian menunjukkan bahwa seluruh fitur dashboard berfungsi dengan baik, meliputi tampilan menu, data hasil pengukuran sensor, grafik, serta riwayat data. Pengujian kinerja sistem dilakukan pada tiga periode waktu, yaitu pagi (07.00–09.00), siang (11.00–13.00), dan sore (15.00–17.00). Pengujian komunikasi data menunjukkan bahwa sistem mampu mengirimkan data ke database secara real-time dengan waktu tunda (delay) kurang dari 1 detik. Hasil validasi sensor menunjukkan bahwa sensor PMS7003 memiliki rata-rata error sebesar 3,11% dengan akurasi 96,89%, sedangkan sensor MiCS-5524 memiliki rata-rata error sebesar 7,10% dengan akurasi 92,90%. Berdasarkan hasil pengujian tersebut, sistem monitoring kualitas udara portable berbasis IoT yang dikembangkan mampu bekerja dengan baik, memiliki tingkat akurasi yang tinggi, serta layak digunakan sebagai perangkat pemantauan kualitas udara secara real-time di kawasan kampus ITS.

Air quality in the entrance roundabout area of Institut Teknologi Sepuluh Nopember (ITS) has not been monitored in real time, even though motor vehicle activities have the potential to increase the concentration of air pollutants, particularly carbon monoxide (CO) and fine particulate matter (PM2.5), which may negatively affect public health and the campus environment. Therefore, this study designed and developed a portable Internet of Things (IoT)-based air quality monitoring system to monitor CO and PM2.5 concentrations. The system utilizes an ESP32-S3 microcontroller, a PMS7003 sensor for PM2.5 measurement, and a MiCS-5524 sensor for CO measurement. The measured data are displayed on an LCD and transmitted to a web-based server for database storage and real-time visualization through a web dashboard. The dashboard has been hosted and is accessible via the itsairsense.com domain. The test results indicate that all dashboard features function properly, including the menu interface, sensor data display, graphical visualization, and historical data records. System performance testing was conducted during three different time periods: morning (07:00–09:00), midday (11:00–13:00), and afternoon (15:00–17:00). Data communication testing demonstrated that the system was able to transmit data to the database in real time with a transmission delay of less than one second. Sensor validation results showed that the PMS7003 sensor achieved an average error of 3.11% with an accuracy of 96.89%, while the MiCS-5524 sensor achieved an average error of 7.10% with an accuracy of 92.90%. Based on these results, the developed IoT-based portable air quality monitoring system operates reliably, provides high measurement accuracy, and is suitable for real-time air quality monitoring in the ITS campus environment.
