Abstract

Monitoring kualitas udara dalam budidaya maggot Black Soldier Fly sangat penting untuk memastikan kondisi optimal bagi kenyamanan lingkungan sekitar. Gas amonia (NH₃) dan hidrogen sulfida (H₂S) yang dihasilkan dari dekomposisi bahan organik dapat menyebabkan bau tidak sedap dan membahayakan kesehatan jika kadarnya terlalu tinggi. Oleh karena itu, diperlukan sistem monitoring yang efektif untuk memantau kadar gas tersebut. Penelitian ini mengembangkan sistem monitoring kadar gas amonia dan hidrogen sulfida berbasis interface Android. Sistem ini menggunakan sensor MQ-135 untuk mendeteksi gas amonia dan sensor MQ-136 untuk mendeteksi gas hidrogen sulfida. Data dari sensor diproses menggunakan mikrokontroler ESP32 yang terhubung dengan aplikasi Android melalui Wi-Fi. Hasil pengukuran kadar gas ditampilkan secara real-time pada aplikasi Android dan disimpan dalam database Firebase untuk menyimpan data. Selain menampilkan data, sistem ini juga dilengkapi dengan alarm berupa buzzer yang akan aktif jika kadar gas melebihi ambang batas yang ditentukan. Dengan demikian, sistem ini tidak hanya memantau tetapi juga memberikan peringatan dini untuk tindakan pencegahan. Pengujian menunjukkan bahwa sensor MQ-135 memiliki akurasi sebesar 98,5% dan MQ-136 sebesar 97,1% dengan toleransi error di bawah 5%. Hasil pengukuran komunikasi antara ESP32 dan Firebase menunjukkan nilai rata-rata delay time sebesar 115,6 ms dan jitter sebesar 115,1 ms, yang tergolong baik hingga sedang berdasarkan standar TIPHON, serta tidak terdapat kehilangan data selama pengujian. Hal ini menunjukkan bahwa sistem mampu mendeteksi variasi konsentrasi gas secara akurat, mengirimkan data dengan stabil.

Air quality monitoring in Black Soldier Fly maggot farming is crucial to ensure optimal conditions for the surrounding environment. Ammonia (NH₃) and hydrogen sulfide (H₂S) gases produced from the decomposition of organic matter can cause unpleasant odors and pose health risks if concentrations are too high. Therefore, an effective monitoring system is needed to measure these gas levels. This research develops a gas concentration monitoring system for ammonia and hydrogen sulfide based on an Android interface. The system uses the MQ-135 sensor to detect ammonia and the MQ-136 sensor to detect hydrogen sulfide. Data from these sensors is processed using an ESP32 microcontroller, which is connected to an Android application via Wi-Fi. The gas concentration readings are displayed in real-time on the Android application and stored in a Firebase database for data logging. In addition to displaying data, the system is also equipped with a buzzer that functions as an alarm if the gas concentration exceeds a specified threshold. Thus, the system not only monitors but also provides early warnings for preventive action. Testing results show that the MQ-135 sensor has an accuracy of 98.5%, while the MQ-136 sensor has an accuracy of 97.1%, with an error tolerance below 5%. Communication measurements between the ESP32 and Firebase indicate an average delay time of 115.6 ms and jitter of 115.1 ms, which fall within good to moderate standards according to TIPHON guidelines, and no data loss occurred during testing. These findings indicate that the system can accurately detect gas concentration variations and transmit data reliably.
