Abstract

Polusi udara merupakan salah satu penyebab utama kematian di dunia, dengan 7 juta kematian setiap tahun menurut World Health Organization (WHO). Oleh karena itu, pemantauan kualitas udara menjadi penting untuk mencegah dampak negatif terhadap kesehatan manusia. Penelitian ini bertujuan untuk merancang dan membangun sistem pemantauan kualitas udara berbasis Wireless Sensor Network (WSN) menggunakan teknologi LoRa dan protokol Modbus RTU. Sistem ini terdiri dari sensor yang mengukur parameter CO2, PM2.5, suhu, dan kelembapan. Data dari sensor dikirimkan ke LoRa gateway dan ditampilkan pada website lokal. Hasil pengujian menunjukkan bahwa sensor PM2.5 (ZH03) memiliki akurasi tinggi dengan rata-rata kesalahan tidak lebih dari 2,17%. Sensor kelembapan (SHT20) memiliki akurasi antara 98,41% hingga 99,68%, dan sensor suhu (SHT20) menunjukkan akurasi antara 94,22% hingga 99,64%. Sensor CO2 (MH-Z19) menunjukkan akurasi antara 98,85% hingga 99,78%. Sistem komunikasi menggunakan LoRa menunjukkan hasil yang memuaskan dengan rata-rata kekuatan sinyal yang diterima sebesar -81,55 dBm, masih dalam kisaran kuat dan stabil untuk teknologi LoRa. Namun, pengujian jarak komunikasi menunjukkan keterbatasan pada jarak 260 meter, dengan terjadinya loss packet sebesar 100% akibat penghalang fisik seperti bangunan beton. Tugas akhir ini berhasil merancang sistem yang efektif untuk pemantauan kualitas udara dengan jangkauan yang lebih luas. Sistem ini dapat membantu masyarakat dan mahasiswa dalam memantau kualitas udara dan mengambil tindakan pencegahan dini terhadap polusi udara.Polusi udara merupakan salah satu penyebab utama kematian di dunia, dengan 7 juta kematian setiap tahun

Air pollution is one of the leading causes of death in the world, with 7 million deaths each year according to the World Health Organization (WHO). Therefore, monitoring air quality is important to prevent negative impacts on human health. This research aims to design and build a Wireless Sensor Network (WSN) based air quality monitoring system using LoRa technology and Modbus RTU protocol. The system consists of sensors that measure CO2, PM2.5, temperature, and humidity parameters. Data from the sensors is sent to the LoRa gateway and displayed on a local website. The test results show that the PM2.5 sensor (ZH03) has high accuracy with an average error of no more than 2.17%. The humidity sensor (SHT20) has an accuracy between 98.41% to 99.68%, and the temperature sensor (SHT20) shows an accuracy between 94.22% to 99.64%. The CO2 sensor (MH-Z19) shows an accuracy between 98.85% to 99.78%. The communication system using LoRa showed satisfactory results with an average received signal strength of -81.55 dBm, still within the strong and stable range for LoRa technology. However, testing the communication distance showed limitations at a distance of 260 meters, with a packet loss of 100% due to physical barriers such as concrete buildings. This final project successfully designed an effective system for air quality monitoring with a wider range. This system can help people and students in monitoring air quality and taking early preventive measures against air pollution
