Abstract

When a forest fire or volcanic eruption must be accompanied by the emergence of gases endanger human health. By utilizing SO2 gas sensor and telemetry system,they are effectively used for the benefit of monitoring gas levels affected areas. The method used  by a field study in Gedong Songo which is now in an active condition give off gases which are still not detected. Through SO2 gas senso gas levels that can be obtained gas levels is 3.57 ppm. All data obtained from sensors will be transmitted in real time to ground stations via the telemetry system. Results of SO2 gas concentration data transmission will be shown through the android app and then analyzed as a follow up of disaster management.Keywords: Disaster, Quadcopter, gas sensors, Telemetry, Android.

Abstract

Sistem HVAC (Heating, Ventilation, and Air Conditioning) digunakan untuk mengatur suhu dan kelembapan demi menciptakan kenyamaan termal dalam ruangan. Pada penelitian ini, dirancang dibangun sebuah Miniatur HVAC skala kecil menggunakan algoritma kendali PID Cascade yang dijalankan pada Raspberry pi 4. PID Cascade dipilih untuk meningkatkan performa sistem dalam merespons gangguan dan perubahan beban termal, dibandingkan kontrol PID tunggal. Pengujian dilakukan untuk membandingkan dua metode tuning PID, yaitu Ziegler-Nichols 1 dan trial and error. Hasil menunjukkan bahwa metode trial and error memberikan respon sistem yang lebih cepat, stabil, dan akurat, dengan error steady-state 0,83%, tanpa overshoot, serta waktu rise dan settling yang memenuhi target performa. Miniatur ini menunjukkan potensi sebagai solusi efisien untuk pengendalian HVAC skala menengah dengan dua variabel fisik yang saling terkait.
