Abstract

MUHAMMAD FATHUR RAHMAN. Kajian Studi Eksperimental Hubungan Respons Resistansi Sensor Gas Metal Oxide Terhadap Suhu dan Kelembaban Udara. Di Bawah Bimbingan WIDYANINGRUM INDRASARI, HARIS SUHENDAR. Sensor gas metal oxide (MOX) merupakan salah satu jenis sensor gas yang mempunyai sensitivitas yang tinggi sehingga terdapat beberapa faktor yang memengaruhi dalam penginderaan sensor gas MOX, seperti suhu dan kelembaban udara. Penelitian ini merancang chamber terkontrol untuk mengkaji hubungan resistansi sensor MOX terhadap suhu dan kelembapan udara menggunakan metode eksperimental. Sistem ini dilengkapi dengan sensor BME280, sensor gas MOX, PTC Air Heater, peltier, heatsink, pompa vakum, keypad dan LCD serta Arduino Mega 2560. Pada penelitian ini telah dilakukan karakterisasi sensor dengan kesalahan relatif pada sensor suhu sebesar 0,653%; kelembaban sebesar 2,507%; dan tekanan sebesar 0,104%. Kemudian, sistem kontrol PID digunakan untuk mengatur suhu dengan parameter terbaik Kp = 0.2, Ki = 0.6, dan Kd = 0.8. Data respons sensor gas MOX dilakukan pada rentang suhu 31°C hingga 40℃ diambil sebanyak 10 kali pengulangan. Hasil penelitian menunjukkan adanya hubungan signifikan antara suhu dan kelembaban dengan resistansi sensor gas MOX. Suhu cenderung memiliki pengaruh langsung terhadap peningkatan resistansi, sedangkan kelembaban menunjukkan pengaruh yang lebih kompleks. Model regresi yang dihasilkan dari analisis data ini memberikan persamaan koreksi yang dapat digunakan untuk memperbaiki akurasi sensor dalam berbagai kondisi lingkungan. Kata kunci.

Experimental Study of the Relationship between the Resistance Response of Metal Oxide Gas Sensors and Air Temperature and Humidity. Supervised by WIDYANINGRUM INDRASARI, HARIS SUHENDAR. Metal oxide (MOX) gas sensor is one type of gas sensor that has high sensitivity so that there are several factors that affect the sensing of the MOX gas sensor, such as temperature and humidity. This study designed a controlled room to study the relationship between MOX sensor resistance to temperature and humidity using experimental methods. This system is equipped with a BME280 sensor, MOX gas sensor, PTC Air Heater, peltier, heatsink, vacuum pump, keypad, LCD and Arduino Mega 2560. In this study, sensor characterization has been carried out with a relative error on the temperature sensor of 0.653%; humidity of 2.507%; and pressure of 0.104%. Then, the PID control system is used to regulate the temperature with the best parameters Kp = 0.2, Ki = 0.6, and Kd = 0.8. MOX gas sensor response data was carried out at a temperature range of 31°C to 40℃ taken 10 times. The results showed a significant relationship between temperature and humidity with the resistance of the MOX gas sensor. Temperature tends to have a direct effect on resistance increase, while humidity shows a more complex effect. The regression model generated from this data analysis provides a correction equation that can be used to improve sensor accuracy under various environmental conditions.
