Abstract

Penelitian tugas akhir yang berjudul “Sistem Deteksi Gas Metana (CH4) Dengan Menggunakan Sensor TGS2611 Dan Sensor MQ-4” ini berfokus mengukur konsentrasi gas metana menggunakan sensor gas TGS2611 dan MQ-4. Penelitian ini dilakukan pada digester kotoran sapi sebagai sampel pengukuran. Pada penelitian ini sensor gas yang digunakan yaitu sensor TGS2611 dan MQ-4, dari hasil pengolahan data pengukuran didapatkan karakteristik dari sensor TGS2611 dan MQ-4, kemudian dari karakteristik diperoleh dapat dibandingkan keandalan dari sensor TGS2611 dan MQ-4. Pada penelitian ini juga dilakukan pengukuran suhu dan kelembapan udara menggunakan sensor DHT11. Pembacaan sensor dilakukan oleh NodeMCU ESP8266 sebagai mikrokontroler pada sistem ini melalui program arduino IDE dan hasilnya ditampilkan ke PLX-DAQ dan LCD. Rangkaian elektronika sensor pada penelitian ini menggunakan rangkaian pembagi tegangan. Berdasarkan fabrikasi Figaro nilai RH sebesar 59Ω, nilai RL diatur melalui potensiometer di sensor sebesar 1000Ω, nilai VRL didapatkan dari output tegangan sensor. Kemudian nilai Vc pada sistem sebagai tegangan input sebesar 3,3 volt. Kemudian nilai Rs akan berubah sesuai reaksi kimia yang terjadi ketika mendeteksi gas. Karakteristik linieritas sensor TGS2611 maupun sensor MQ-4 terbentuk grafik yang logaritmik atau grafik non linier hubungan antara tegangan sensor (volt) dengan konsentrasi gas metana (ppm). Pada sensor TGS2611 jangkauan pengukuran sistem sekitar 4700 ppm - 6300 ppm, sensitivitas sensor sebesar 0.5433 Volt/ppm. Sedangkan pada sensor MQ-4, jangkauan pengukuran sistem sekitar 4000 ppm - 5100 ppm, sensitivitas sensor sebesar 0.5639 Volt/ppm. Keandalan sistem deteksi gas metana menggunakan sensor TGS2611 adalah 93,45% terhadap temperatur dan 97,22% terhadap kelembapan. Sedangkan keandalan sistem deteksi gas metana menggunakan sensor MQ-4 adalah 98,28% terhadap temperatur 98,61% terhadap kelembapan.

The final research project entitled "Methane Detection System (CH4) Using the TGS2611 Sensor and MQ-4 Sensor" focuses on measuring the concentration of methane gas using the TGS2611 and MQ-4 gas sensors. This research was conducted on a cow dung digester as a measurement sample. In this study the gas sensors used were the TGS2611 and MQ-4 sensors, from the results of processing the measurement data the characteristics of the TGS2611 and MQ-4 sensors were obtained, then the characteristics obtained could be compared to the reliability of the TGS2611 and MQ-4 sensors. In this study, measurements of temperature and humidity were also carried out using the DHT11 sensor. Sensor readings are carried out by NodeMCU ESP8266 as a microcontroller in this system via the Arduino IDE program and the results are displayed on the PLX-DAQ and LCD. The sensor electronics circuit in this study uses a voltage divider circuit. Based on Figaro's fabrication, the RH value is 59Ω, the RL value is adjusted via a potentiometer on the sensor at 1000Ω, the VRL value is obtained from the sensor voltage output. Then the value of Vc in the system as the input voltage is 3.3 volts. Then the Rs value will change according to the chemical reaction that occurs when detecting gas. The linearity characteristics of the TGS2611 sensor and the MQ-4 sensor form a logarithmic graph or non-linear graph of the relationship between the sensor voltage (volts) and the concentration of methane gas (ppm). On the TGS2611 sensor the system measurement range is around 4700 ppm - 6300 ppm, the sensor sensitivity is 0.5433 Volts/ppm. Whereas on the MQ-4 sensor, the system measurement range is around 4000 ppm - 5100 ppm, the sensor sensitivity is 0.5639 Volts/ppm. The reliability of the methane gas detection system using the TGS2611 sensor is 93.45% for temperature and 97.22% for humidity. While the reliability of the methane gas detection system using the MQ-4 sensor is 98.28% for temperature and 98.61% for humidity.
