      Abstract
      Minuman sari buah jeruk merupakan minuman populer di masyarakat yang hadir dalam bentuk minuman serbuk instan dan minuman ready to drink. Minuman sari buah jeruk sangat berpotensi dikembangkan di Indonesia. Evaluasi sensori berperan meningkatkan mutu minuman sari buah jeruk di perusahaan. Evaluasi sensori deskriptif menggunakan metode konvensional menyajikan profil sensori yang lengkap, namun metode ini memerlukan waktu yang lama dan biaya yang besar. Penelitian ini menggunakan metode Quantitative Descriptive Analysis (QDA) dan Optimized Descriptive Profile (ODP). Penelitian ini bertujuan mengidentifikasi metode Optimized descriptive profile (ODP) memiliki keefektifan yang sama dengan metode konvensional atau Quantitative Descriptive Analysis (QDA), dan mengevaluasi kinerja panelis dalam melakukan uji sensori. Sampel yang digunakan yaitu 6 produk minuman sari buah jeruk komersial dengan menggunakan panelis terlatih dan semi terlatih karyawan PT XYZ. Hasil pengujian 6 produk minuman sari buah jeruk komersial yaitu masing-masing produk memiliki karakteristik dominan yang spesifik. Profil sensori minuman sari buah jeruk metode QDA dan ODP memiliki kemiripan dari atribut dominan yang dihasilkan, namun uji statistik t-test menghasilkan sedikit perbedaan pada beberapa atribut. Sampel produk minuman sari buah jeruk C pada metode ODP tidak berbeda nyata dengan metode QDA pada taraf signifikansi 0,05 untuk semua atribut. Panelis semi terlatih PT XYZ Lokasi II memiliki kemampuan repeatability dan reproducibility yang tidak jauh berbeda dengan panelis terlatih PT XYZ Lokasi
       
      Orange juice drink is a popular drink in the community which comes in the form of instant powdered drinks and ready-to-drink beverages. Orange juice drink has the potential to be developed in Indonesia. Sensory evaluation plays a role in improving the quality of orange juice drinks in the company. Descriptive sensory evaluation using conventional methods presents a complete sensory profile, but this method requires a long time and costs a lot. This study uses Quantitative Descriptive Analysis (QDA) and Optimized Descriptive Profile (ODP) methods. This study aims to identify the Optimized descriptive profile (ODP) method which has the same effectiveness as the conventional method or Quantitative Descriptive Analysis (QDA), and evaluate the performance of panelists in conducting sensory tests. The samples used were 6 commercial orange juice drink products using trained panelists and semi-trained PT XYZ employees. The test results for 6 commercial orange juice drink products have a specific dominant characteristic. The sensory profile of the orange juice drink in the QDA and ODP methods has similarities in the resulting dominant attributes, but the t-test statistical test produces slight differences in some attributes. Sample of orange drink C in the ODP method was not significantly different from the QDA method at a significance level of 0.05 for all attributes. Semi-trained panelists at PT XYZ Location II have repeatability and reproducibility capabilities that are not much different from the trained panelists at PT XYZ Location 1.
