Abstract
Perkembangan dunia industri di Indonesia mengalami perkembangan yang pesat dan tidak lepas dari sektor formal maupun informal. Salah satu perkembangan industri informal yang banyak diminati salah satunya adalah pekerjaan di bidang pengelasan. Kegiatan proses pengelasan menghadapi banyak risiko dengan tingkat bahaya yang cukup tinggi seperti panas, radiasi, ledakan, gas, dan asap beracun serta menghasilkan berbagai macam polutan berupa gas dan partikulat sebagai sisa emisi pengelasan. Penelitian bertujuan untuk mengembangkan sistem monitoring kualitas udara pada bengkel las indoor menggunakan metode real-time berbasis internet of things (IoT). Perancangan sistem monitoring kualitas udara pada bengkel las indoor menggunakan ESP32 sebagai pengendali utama, modul gas MQ-7, modul suhu DHT22, modul optical dust GP2Y1010AU0F sebagai input, dan LCD 20×4 sebagai output untuk menampilkan data nilai gas CO, suhu, dan debu yang kemudian ditampilkan pada halaman dashboard platform Ubidots sebagai monitoring untuk menampilkan data pengukuran pembacaan nilai gas CO, suhu, dan debu. Penelitian menggunakan metode Research and Development (R&D) dengan pendekatan V-Model yang mencakup tahap analisis kebutuhan hingga pengujian unit dan sistem secara menyeluruh. Hasil pengujian menunjukkan bahwa sistem mampu menampilkan informasi data gas CO, suhu, serta debu(pm2.5) secara real-time pada tampilan layar LCD dan memberikan interface monitoring berbasis internet of things (IoT) pada dashboard platform Ubidots dan menghasilkan persentase error pada modul gas MQ-7 sebesar 0.57%, lalu persentase error pada modul suhu DHT22 sebesar 0.01%, kemudian persentase error pada modul optical dust GP1Y1010AU0F sebesar 0.20%. Dapat disimpulkan bahwa Sistem Monitoring Kualitas Udara Pada Bengkel Las Indoor Menggunakan Metode Real-Time Berbasis Internet Of Things (IoT) mampu bekerja sesuai dengan fungsi yang diharapkan. ***** The development of the industrial world in Indonesia is experiencing rapid development and cannot be separated from the formal and informal sectors. One of the developments in the informal industry that is in great demand is work in the field of welding. Welding process activities face many risks with a high level of danger such as heat, radiation, explosions, gases, and toxic fumes and produce various kinds of pollutants in the form of gases and particulates as residual welding emissions. The research aims to develop an air quality monitoring system in indoor welding workshops using real-time methods based on the internet of things (IoT). The design of the air quality monitoring system in the indoor welding workshop uses ESP32 as the main controller, MQ-7 gas module, DHT22 temperature module, and GP2Y1010AU0F optical dust module as input, and 20x4 LCD as output to display CO gas value data, temperature, and dust which is then displayed on the dashboard platform Ubidots page as monitoring to display measurement data reading CO gas value, temperature, and dust. The research uses the Research and Development (R&D) method with the V-Model approach that includes the needs analysis stage to thorough unit and system testing. The test results show that the system is able to display data information in the form of CO gas, temperature, and dust (pm2.5) in real-time on the LCD screen display and provide an internet of things (IoT)-based monitoring interface on the dashboard platform Ubidots and produce a percentage error on the MQ-7 gas module of 0.57%, then the percentage error on the DHT22 temperature module of 0.01%, then the percentage error on the GP1Y1010AU0F optical dust module of 0.20%. It can be concluded that the Air Quality Monitoring System in Indoor Welding Workshop Using Real-Time Method Based on Internet of Things (IoT) is able to work in accordance with the expected functions.
