Abstract
Abstrak: Saat ini pemalsuan produk atsiri menjadi salah satu isu yang sangat menarik, khususnya nilam. Pemalsuan biasanya merupakan pencampuran antara produk yang bernilai rendah dengan yang bernilai tinggi. Tujuan dari penelitian ini yaitu untuk mendapatkan informasi tentang teknologi NIRS sebagai metode cepat dan tepat dalam memprediksi kadar minyak kelapa yang dicampurkan didalam minyak nilam Alat yang digunakan pada penelitian ini antara lain GCMS, Thermo Nicolet Antaris II TM, botol kaca 3 ml, gelas kimia, timbangan digital, micropipette, Magnetic Stirrer, dan Software Unscrambler X versi 10.3. Bahan yang digunakan pada penelitian ini yaitu minyak nilam (Crude Oil) dari PUI PT Nilam Atsiri Research Center (ARC) Universitas Syiah Kuala dan minyak kelapa yang diperoleh dari pasaran. Hasil penelitian ini menunjukkan bahwa Teknologi near infrared reflectance spectroscopy (NIRS) dengan metode partial least square (PLS) telah berhasil mendapatkan prediksi kadar minyak kelapa yang dicampurkan didalam minyak nilam yaitu pretreatment Derivative 1 (D1). Metode koreksi yang terbaik dalam mempediksi kadar minyak kelapa yang dicampurkan didalam minyak nilam adalah pretreatment Derivative 1 (D1), pretreatmen ini berhasil memperbaiki model yang dibangun oleh PLS, dimana model PLS-D1 memiliki ikatan variable dengan latent variable 6, nilai RPD sebesar 3,13 nilai korelasi (r) sebesar 0.94, nilai koefisien determinasi (R2) sebesar 0.89 dan nilai root mean erorr calibration (RMSEC) sebesar 9,17.
