Abstract

Permasalahan umum di kawasan perkotaan adalah permasalahan lingkungan mengenai isu-isu pencemaran udara. Bahan pencemar udara merupakan hasil dari proses alam maupun kegiatan dan aktivitas manusia yang dapat mengakibatkan menurunnya kualitas udara. Walaupun banyak masyarakat yang sudah mengetahui apa saja resiko menghirup udara tercemar, namun hal tersebut sering diabaikan karena masih kurangnya informasi mengenai kadar senyawa yang dihirup secara real time di lingkungannya. Sedangkan, banyak efek yang ditimbulkan dari polusi udara, antara lain kesulitan bernapas, batuk, asma, emfisema hingga penyakit yang lebih parah. Seiring dengan meningkatnya konsentrasi senyawa polutan, pendeteksian terhadap konsentrasi senyawa ini menjadi penting untuk dapat melakukan tindakan pencegahan terhadap berlebihnya kadar senyawa berbahaya di dalam atmosfer. Oleh karena itu, perlu dilakukan pengukuran dan monitoring kualitas udara yang dilengkapi early warning system. Pada penelitian ini, telah berhasil dilakukan uji validasi komponen dimana dihasilkan level karbon dioksida yang diukur oleh sensor NDIR dengan akurasi sebesar 98,87%, level karbon monoksida yang diukur oleh sensor MQ-7 dengan akurasi sebesar 96,31%, serta sensor DHT22 memiliki nilai akurasi sebesar 99,72% untuk variabel temperatur dan sebesar 98,85% untuk variabel kelembaban. Sistem monitoring online yang ditampilkan pada website serta sistem monitoring offline menggunakan LCD TFT berhasil menampilkan data CO, CO₂, NO₂, temperatur dan kelembaban udara. Selain itu, early warning system berfungsi sesuai dengan parameter di setiap kondisi. Sistem monitoring yang telah diuji memiliki performa dengan waktu delay rata-rata sebesar 6 - 7 detik antara monitoring online dan offline. Waktu delay tersebut diakibatkan karena koneksi internet yang kurang baik sehingga mempengaruhi proses pengiriman data dari hardware ke database.

A common problem in urban areas is the environmental issue of air pollution. Air pollution is the result of natural processes as well as human activities and activities that can lead to a decline in air quality. Although many people already know the risks of inhaling polluted air, it is often overlooked because there is still a lack of information about the real-time levels of inhaled compounds in the environment. Meanwhile, many effects from air pollution include difficulty breathing, coughing, asthma, emphysema to more severe illnesses. As the concentration of pollutants increases, detection of concentrations of these compounds becomes important to prevent excess levels of hazardous compounds in the atmosphere. Therefore, it is necessary to measure and monitor the air quality that is equipped with an early warning system. In this study, a component validation test has been carried out where carbon dioxide levels measured by NDIR sensors are 99.33%, carbon monoxide levels measured by MQ-7 sensors with 98.85%, and DHT22 sensors have 99.72% accuracy for temperature variables and 98.85% for humidity variable. Online monitoring systems displayed on websites and offline monitoring systems using TFT LCD successfully display CO, CO₂, NO₂, data, temperature and humidity. In addition, the initial warning system functions according to the parameters of each condition. The monitoring system that has been tested has performance with an average delay of 6 to 7 seconds between online and offline monitoring. This delay is due to an unfavorable internet connection that affects the process of sending data from hardware to databases.
