ABSTRAKPenelitian ini bertujuan untuk mengevaluasi level kunyit yang tepat sehingga dapat meningkatkan kualitas bakso daging itik. Percobaan ini menggunakan Rancangan Acak Lengkap, yang terdiri dari empat perlakuan yaitu P0 (tanpa pemberian kunyit), P1 (pemberian kunyit taraf 2,5%), P2 (pemberian kunyit taraf 5%), dan P3 (pemberian kunyittaraf 7,5%), masing-masing perlakuan terdiri dari tiga ulangan. Hasil penelitian menunjukkan bahwa pemberian kunyit berpengaruh tidak nyata (P>0,05) terhadap variabel susut masak, daya mengikat air, pH dan tekstur bakso daging itik, tetapi nyata (P<0,05) meningkatkan skor warna, menurunkan derajat keamisan dan variabel sifat organoleptik rasa. Hasil yang berpengaruh nyata diuji lanjut menggunakan Orthogonal polynomial dengan menghasilkan persamaan linear dan kuadratik. Dari hasil penelitian disimpulkan bahwa penambahan kunyit 2,5% hingga 7,5% tidak menurunkan kualitas fisik (susut masak, pH, dan DMA). Penambahan kunyit 2,5% dapat mempertahankan cita rasa dan penerimaan umum panelis terhadap bakso daging itik.Kata kunci : Kunyit (Curcuma domestica), kualitas fisik, daging itik

Based on the superiority avoiding the matrix equation to be morbid for those fitting functions constructed by orthogonal base, the Legendre orthogonal polynomial is adopted to fit the experimental data of concrete uniaxial compression stress-strain curves under the frame of least-square. With the help of FORTRAN programming, 3 series of experimental data is fitted. And the fitting effect is very satisfactory when the item number of orthogonal base is not less than 5. What’s more, compared with those piecewise fitting functions, the Legendre orthogonal polynomial fitting function obtained can be introduced into the nonlinear harden-soften character of concrete constitute law more convenient because of its uniform function form and continuous derived feature. And the fitting idea by orthogonal base function will provide a widely road for studying the constitute law of concrete material.

Abstract The goal of this paper is to investigate the missing part of the story about the relationship between the orthogonal polynomial ensembles and Painlevé equations. Namely, we consider the $q$-Racah polynomial ensemble and show that the one-interval gap probabilities in this case can be expressed through a solution of the discrete $q$-P$\left (E_7^{(1)}/A_{1}^{(1)}\right )$ equation. Our approach also gives a new Lax pair for this equation. This Lax pair has an interesting additional involutive symmetry structure.
