Abstract

An electronic nose is a device designed to sense, classify, and recognize a product based on its aroma. The electronic nose is generally designed from four main parts, namely: sample handling and delivery system, detector system, signal conditioning and preprocessing, and pattern recognition software. The detector section is a series of gas sensors that have different levels of gas sensitivity and selectivity. The sensor used in the electronic nose sometimes has low sensitivity, resulting in the undetected material being tested. Therefore, the electronic nose requires a selected sensor to optimally detect certain scents. The purpose of this study was to analyze the performance of the MOS sensor on an electronic nose for synthetic flavor classification. The types of gas sensors used in the electronic nose design are MQ 2, MQ 3, MQ 4, MQ 5, MQ 6, MQ 7, MQ 8, and MQ 9. The test sample used is liquid synthetic flavors with two different aroma variants (jackfruit and pandan). The gas sensor response analysis consists of two stages, namely pre-treatment data processing and pattern classification based on the principal component analysis method. The results of PCA show that the MQ sensor can classify the two samples well. The total variance of PC 1 and PC 2 for the MQ sensor-based electronic nose is 96,36%.
