Deteksi Kemurnian Air Zamzam Menggunakan Metode Spektrofotometri Near Infra Red (NIR) dan Kemometrik
Abstract: Zamzam water is
called the holy water that is located in the heard city of Mecca. Zamzam is
believed to have many benefits for health so widely consumed by Moslems
throughout the world. In 2010, the Government of Saudi Arabia implementing
rules ban export of zamzam water for commercial purposes, but zamzam water are
sold freely in the world. In this research, the determination of the purity of
Zamzam water was developed. The method used was NIR spectroscopy combined with
multivariate statistical methods (chemometric). Zamzam water simulation were
consist of pure Zamzam water, mineral water, and a mixture of Zamzam water and
mineral water with a concentration range of 0% -100%. Chemometric model used
are PLS, LDA, SIMCA, and SVM. LDA classification model is the best chemometric
model with 100% recognition ability and prediction ability respectively. NIR
spectroscopy and chemometric method have been applied succesfully to detect the
purity of Zamzam water samples which marketed in Jember.
