| dc.description.abstract | PT. XYZ sebagai perusahaan produsen mie instan dan teh dalam kemasan belum memiliki sistem evaluasi kemampuan panelis yang terstandar dan terklasifikasi secara objektif. Penelitian ini bertujuan menilai kemampuan diskriminatif panelis melalui uji triangle dan ranking, menganalisis performa panelis, serta menetapkan sistem grading panelis berbasis performa sensori. Data kuantitatif diperoleh dari 26 panelis semi terlatih melalui uji ranking (5 rasa dasar dan warna) dan uji triangle (aroma dan produk perusahaan). Hasil uji Friedman dan Binomial menunjukkan seluruh sampel valid (p<0,05). Akurasi tertinggi pada rasa manis (100%) dan teh (96,2%), terendah pada umami (69,2%) dan mie (53,8%). Sistem grading menghasilkan 13 Grade A, 10 Grade B, 2 Grade C1, dan 1 Grade C2. Validasi Kruskal-Wallis (p=0,001) dan Mann-Whitney (a=0,017) membuktikan perbedaan antar grade signifikan. Sistem ini diimplementasikan dalam Work Instruction sebagai acuan kalibrasi panelis di PT. XYZ. | |
| dc.description.abstract | PT. XYZ, a manufacturer of instant noodles and packaged tea, lacks a standardized and objectively classified panelist capability evaluation system. This study aimed to assess panelists' discriminative ability through triangle and ranking tests, analyze panelist performance, and establish a sensory performance-based grading system. Quantitative data were obtained from 26 semi-trained panelists through ranking tests (5 basic tastes and color) and triangle tests (aroma and company products). Friedman and Binomial tests showed all samples were valid (p<0.05). The highest accuracy was in sweetness (100%) and tea (96.2%), while the lowest were in umami (69.2%) and noodles (53.8%). The grading system resulted in 13 Grade A, 10 Grade B, 2 Grade C1, and 1 Grade C2. Kruskal-Wallis (p=0.001) and Mann-Whitney (a=0.017) validations proved significant differences between grades. This system was implemented in a Work Instruction as a reference for panelist calibration at PT. XYZ | |
