The unstable availability and trading system of beef has resulted in many acts of pork adulteration by irresponsible parties. This action disadvantages consumers, especially Muslim consumers. Based on this, a rapid detection method for aroma identification is needed. The rapid aroma detection in this research uses an electronic nose based on MQ3 and MQ5 sensors with Arduino Mega as a microcontroller. Digital data displayed using Cool Term software is processed using Microsoft Excel and analyzed descriptively. The sensing process uses beef and pork with a temperature of 40 to 120 oC at every 10 oC increase. Based on the results, the optimum sensing temperature to differentiate beef and pork is at 70 oC. The sensor response pattern and beef and pork flavor print showed significant differences. Using PCA analysis with a total score plot of 100% shows that the electronic nose based on MQ3 and MQ5 sensors can detect differences in the aroma of beef and pork.
