Abstract
The objective of this study is to evaluate the SIMCA method and NIR spectroscopy for the non-invasive and non-destructive classification of Indonesian specialty coffees that come from two geographical origins: Gayo coffee from Aceh 10 samples and Wamena from Papua 10 samples. All samples were roasted at the same condition (medium roasting at a temperature of 200°C for 10 minutes) and were ground using a home coffee grinder and then sieved using 50 mesh to obtain a homogenous particle size of 297 micrometers. Spectral data in the short and long near infrared range of 650–1650 nm was measured in a diffuse reflectance mode using two handheld spectrometers equipped with an integrating sphere (ISP-REF, Ocean Optics, USA). The result demonstrated that the classification was satisfied with 100% accuracy, sensitivity, and specificity.
