Identification of Betel Leaf Wave Numbers (Piper sp.) Using Fourier Transform Infrared (FTIR) Spectroscopy Methods and Principal Component Analysis (PCA)
Abstract
Research has been carried out on the identification of betel leaf (Piper sp.) wavenumbers using Fourier transform infrared (FTIR) spectroscopy and Principal Component Analysis (PCA) methods. The kinds of betel leaf used are red betel (Piper Crocatum), green betel (Piper Betle L.), and black betel (Piper Betle V.). Tests were carried out on betel leaf powder with a betel mass ratio of 4:1 KBr, 0.011528 g and 0.002882 g, respectively. The results of characterization by FTIR showed the presence of functional groups C-H, C = O, C = N, C = C, C-N, C-O, and C-Cl on red, green, and black betel leaves. The results of the PCA analysis provide the value of the wave number which is the identity of betel in the range 1670-1679 cm-1 and strengthened by the results of the K-Nearest Neighborhood (KNN) analysis.
