Abstract

The increasing number of motor vehicles in urban areas causes a decline in air quality due to emissions such as carbon monoxide (CO) and carbon dioxide (CO₂). If left unchecked, similar conditions may occur in Cepu City. This research developed an air quality monitoring and early warning system based on the Internet of Things (IoT) using an MQ-135 sensor to detect CO and CO₂ and a DHT22 sensor for temperature and humidity. The collected data are transmitted to the Thingspeak platform and sent to users via Telegram notifications. The device was tested for seven days at two different locations in Cepu. The results show that the system can provide real-time air quality information and early warnings to help the public take precautions against air pollution impacts

Abstract

Penelitian ini mengembangkan sistem penyiraman otomatis dan pemantauan kelembaban tanah berbasis NodeMCU ESP8266, modul nRF24L01, dan aplikasi Blynk untuk meningkatkan efektifitas pengelolaan irigasi. Sistem memantau kelembaban tanah secara real-time dan mengendalikan penyiraman secara otomatis berdasarkan nilai kelembaban yang terukur. Hasil pengujian menunjukkan sistem bekerja sesuai rancangan, yaitu mengaktifkan penyiraman saat kelembaban tanah berada di bawah 60% dan menghentikannya ketika kelembaban mencapai nilai yang ditentukan. Penerapan Internet of Things (IoT) dilakukan melalui pemantauan kondisi tanah yang dilakukan secara jarak jauh melalui aplikasi Blynk. Selain itu, hasil pengujian komunikasi nirkabel menggunakan modul nRF24L01 menunjukkan jarak transmisi maksimum mencapai 40 meter pada pengujian di luar ruangan dan 10 meter pada pengujian di dalam ruangan. Hasil penelitian menunjukkan bahwa sistem mampu mendukung pengelolaan penyiraman yang lebih efektif dan otomatis.
