IDENTIFIKASI DAN AUTENTIKASI JAHE MERAH MENGGUNAKAN KOMBINASI SPEKTROSKOPI FTIR DAN KEMOMETRIK (Identification and Authentication of Jahe Merah Using Combination of FTIR Spectrocopy and Chemometrics)
FTIR spectroscopy combined with principal component analysis and discriminant analysis were used for identification and authentication of jahe merah from its related species namely jahe emprit and jahe gajah. FTIR spectra of all samples were recorded in the wavenumber range 4000-400 cm-1 and then su...

description |
FTIR spectroscopy combined with principal component analysis and discriminant analysis were used for identification
and authentication of jahe merah from its related species namely jahe emprit and jahe gajah. FTIR spectra of all
samples were recorded in the wavenumber range 4000-400 cm-1 and then subjected for preprocessing signal such
as normalization and baseline correction. Combination of FTIR spectra with some chemometrics method such as
principal component analysis and discriminant analysis were used to distinguish the three varieties of ginger. By using
discriminant analysis, the three varieties of ginger were classified according to its variety. The developed method could
be used for identification and authentication of jahe merah.

ABSTRAK
Spektroskopi FTIR dan kombinasinya dengan analisis komponen utama dan analisis diskriminan telah digunakan
untuk identifikasi dan autentikasi jahe merah dari dua spesies yang berkerabat dengannya yaitu jahe emprit dan jahe
gajah. Seluruh contoh dibuat spektrum FTIR pada kisaran bilangan gelombang 4000-400 cm-1 dan diberi perlakuan
pendahuluan seperti normalisasi dan koreksi garis dasar. Kombinasi spektrum FTIR dengan beberapa metode
kemometrik seperti analisis komponen utama dan analisis diskriminan digunakan untuk membedakan ketiga varietas
jahe. Analisis diskriminan dapat mengelompokkan ketiga varietas jahe sesuai dengan jenis varietasnya. Metode yang
dikembangkan ini dapat digunakan untuk tujuan identifikasi dan autentikasi jahe merah.
