    Codot coffee from Tanggamus, Lampung is one of Indonesian specialty coffee with a very limited production. In this research, an authentication study for the Codot ground roasted coffee was conducted using UV-vis spectroscopy and chemometrics. A total of 330 samples of pure and adulterated Codot coffee was prepared. The adulterated Codot coffee samples were intentionally created by adding a regular coffee (non-Codot coffee) into pure Codot coffee samples with three levels of adulterations: low (10-20%), medium (30-40%), and high level (50-60%). All samples were 0,29 mm in particle size. The extraction procedure was performed with hot distilled water (98°C). The spectral data of coffee samples were acquired using a benchtop UV-visible spectrometer in the range of 190-1100 nm using a transmittance mode. The result showed that the pure and adulterated samples could be discriminated along PC1 and PC2 axis. The classification model was developed using LDA with 90,91% of accuracy could be obtained. The LDA model was used to classify the new samples and resulted in a sensitivity (SEN) of 100%, specificity (SPEC) of 76,67%, precision (PREC) of 78,13%, and accuracy (ACC) of 87,27% could be obtained. Using PLS regression, a PLS model was developed to quantify the percentages of Codot coffee adulteration and resulted in high of coefficient of determination both in calibration and validation (R2kal = 0,99 and R2val = 0,98). These results showed that UV-vis spectroscopy and chemometrics are suitable for authentication of Codot specialty coffee with RMSEP = 2,68% and RPD in prediction of 6,49.   Keywords: authentication, LDA, PCA, PLS regression, UV-vis spectroscop

    Kopi spesialti arabika Java Preanger kultivar Typica, Sigarar Utang, dan Yellow Bourbon saat ini tersedia di pasar kopi premium dengan harga mahal dan saat ini menjadi salah satu target pemalsuan kopi. Penelitian ini bertujuan untuk mengevaluasi aplikasi metode spektroskopi UV dan metode PLS-DA (partial least squares-discriminant analysis) untuk autentikasi cepat kopi spesialti arabika Java Preanger dengan tiga kultivar berbeda. Sampel kopi bubuk spesialti arabika dan robusta disiapkan sebanyak 550 sampel dengan berat 1 g untuk setiap sampel. Seluruh sampel diekstraksi dengan prosedur standar dan diencerkan dengan perbandingan 1:70 (volume/volume). Sampel kopi yang telah diencerkan kemudian diambil sebanyak 3 mL, dimasukkan ke dalam sel kuvet kuarsa, dan diambil spektranya menggunakan alat spektrometer UV-visible di rentang panjang gelombang 190-400 nm dengan interval 1 nm. Hasil PCA spektra hasil pengolahan di panjang gelombang 250-400 nm menunjukkan tiga kultivar kopi spesialti arabika dan kopi robusta dapat dibedakan dengan jelas dan terletak di klaster yang berbeda. Namun kopi spesialti arabika Typica dan Sigarar Utang terletak di klaster yang saling berdekatan dan sebagian sampel saling bertumpuk menunjukkan kedua kultivar kopi arabika tersebut memiliki kemiripan. Hasil PLS-DA spektra hasil pengolahan di panjang gelombang 250-400 nm menunjukkan model klasifikasi yang dibangun dapat digunakan untuk klasifikasi kopi robusta dan kopi arabika dengan tiga kultivar berbeda dengan akurasi klasifikasi mencapai 97.8 sampai 100%.Java Preanger arabica specialty coffee of Typica, Sigarar Utang, and Yellow Bourbon is currently available in the premium coffee market at high prices and is currently one of the targets for coffee fraud. This study aims to evaluate the use of the UV spectroscopy method and the PLS-DA (partial least squares-discriminant analysis) method for rapid authentication of Java Preanger arabica specialty coffee with three different cultivars. Samples of arabica specialty ground roasted coffee and robusta were prepared for 550 samples with a weight of 1 g for each sample. All samples were extracted by standard procedures and diluted in a ratio of 1:70 (volume/volume). The diluted coffee sample was then taken as much as 3 mL, inserted into a quartz cuvette cell, and the spectra were taken using a UV-visible spectrometer in the wavelength range of 190-400 nm with 1 nm intervals. The results of the PCA transformation spectra at a wavelength of 250-400 nm showed that three cultivars of arabica specialty and robusta coffee could be distinguished and were in different clusters. However, Typica and Sigarar Utang arabica specialty coffees are in clusters that are close to each other and some of them overlap each other, indicating that the two arabica specialty coffees have similarities. The results of PLS-DA transformation spectra at a wavelength of 250-400 nm show that the developed classification model can be used for the classification of robusta and arabica coffee with three different cultivars with classification accuracy reaching 97.8 to 100%
