Abstract

Polusi udara merupakan masalah kesehatan yang signifikan di kota-kota besar di seluruh dunia, yang memengaruhi semua kelompok usia, termasuk bayi, remaja, dan wanita hamil. Organisasi Kesehatan Dunia (WHO) telah mengaitkan polusi udara dengan peningkatan risiko stroke, penyakit jantung, penyakit paru obstruktif kronik, kanker paru-paru, pneumonia, dan katarak. Terlepas dari kesadaran akan risiko-risiko ini, data real time tentang kualitas udara seringkali kurang tersedia, sehingga diperlukan sistem yang menyediakan informasi kualitas udara untuk mencegah paparan yang berlebihan. Dalam penelitian ini, telah dikembangkan sistem pemantauan kualitas udara berbasis IoT yang mengirimkan data ke database dan menampilkannya di situs web. Selain itu, dilengkapi pemantauan kualitas udara dengan LCD TFT untuk pemantauan secara lokal. Sistem ini mengukur kadar CO, CO₂, NO₂, suhu, dan kelembaban, serta menyertakan early warning system yang diaktifkan berdasarkan ambang batas tertentu. Uji akurasi sensor telah dilakukan dan mendapatkan nilai akurasi untuk masing-masing sensor sebagai berikut sensor CO MQ9 sebesar 82,29% dan sensor CO MQ7 sebesar 87,37%, sensor CO2 MG811 sebesar 95,07% dan sensor CO2 NDIR sebesar 97,40%. Sensor DHT22 pada alat 1 memiliki akurasi 99,48% untuk temperature dan 97,65% untuk kelembaban, sedangkan sensor DHT22 pada alat 2 memiliki akurasi 99,67% untuk temperatur dan 98,09% untuk kelembaban. Pengujian kinerja sistem pemantauan kualitas udara memiliki performa delay rata-rata 3 hingga 7 detik antara pemantauan lokal dan situs web yang diakibatkan konektivitas internet. Selain itu, push notification smartphone melalui WhatsApp berhasil dikirim ketika kondisi kualitas udara sangat tercemar dan pada waktu yang dijadwalkan. Sistem pemantauan ini dapat dilakukan pada dua lokasi berbeda dan dapat menampilkan kualitas udara dengan kondisi berbeda secara bersamaan.

Air pollution is a significant health concern in major cities around the world, affecting all age groups, including infants, adolescents and pregnant women. The World Health Organization (WHO) has linked air pollution to an increased risk of stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, pneumonia and cataracts. Despite the awareness of these risks, real time data on air quality is often lacking, so a system that provides air quality information is needed to prevent overexposure. In this research, an IoT-based air quality monitoring system has been developed that sends data to a database and displays it on a website. In addition, it features air quality monitoring with a TFT LCD for local monitoring. The system measures CO, CO₂, NO₂, temperature, and humidity levels, and includes an early warning system that is activated based on certain thresholds. Sensor accuracy tests have been carried out and obtained accuracy values for each sensor as follows CO MQ9 sensor at 82.29% and CO MQ7 sensor at 87.37%, CO2 MG811 sensor at 95.07% and CO2 NDIR sensor at 97.40%. The DHT22 sensor in device 1 has an accuracy of 99.48% for temperature and 97.65% for humidity, while the DHT22 sensor in device 2 has an accuracy of 99.67% for temperature and 98.09% for humidity. Performance testing of the air quality monitoring system has an average performance delay of 3 to 7 seconds between local monitoring and the website due to internet connectivity. In addition, smartphone push notifications via WhatsApp were successfully sent when air quality conditions were highly polluted and at the scheduled time. This monitoring system can be carried out at two different locations and can display air quality with different conditions simultaneously.
