Judul: Pengaruh Penambahan Minyak Biji Bunga Matahari (Helianthus annuus) dengan Level yang Berbeda terhadap Performa Domba Jantan Muda
Abstrak: This research aims to analyze the effect of addition sunflower oil in the diet on the performance of young rams. This research uses a randomized block design with 3 treatments and 3 replications. Treatment in this study is the ration without the addition of sunflower seed oil (M0%), the addition of 4% ration with sunflower seed oil (M4%), and ration with the addition of 6% sunflower oil (M6%). The content total digestible nutrien (TDN) of M0%, M4% and M6% respectively for 75.84%, 79.24% and 80.94%. Variables measured were dry matter intake, nutrient intake, body weight gain and feed conversion. Data were analyzed using analysis of variance (ANOVA) and if the result showed significant different, it will be followed by contrast ortogonal. The results of this research indicate that the addition of sunflower oil to the diet was not significantly different (p>0.05) for consumption of crude protein, crude fiber, TDN, Ca and P, but significant effect (p>0.05) on dry matter intake and crude fat. The addition of sunflower seed oil by 4% (M4%) to the diet can improve dry matter and crude fat intake also showed good result on nutrient intake and body weight gain sheep.

Abstrak: A study was conducted using sheep to observe and to evaluate the quality of ration with different sunflower seed oil on digestibility nutrients and milk composition. This study used Completely Randomized Design (CRD) with 4 treatments, ie P0 (without the addition of sunflower seed oil or control), P1 (the addition of sunflower seed oil at 2%), P2 (the addition of sunflower seed oil at 4%), P3 (the addition of sunflower oil at 6%) and 3 replications. The data obtained from the study were analyzed using analysis of variance (Analysis of Variance/ANOVA) and when the result of the analysis showed significant differences, it will be followed by Ortogonal Polynomial Test. The result showed that the treatments did not significantly effect (P>0.05) nutrient digestibility, total digestibility nutrient, absorpstion minerals (Ca and P) and milk composition. The treatments significantly effect (P<0.01) fat intake. The addition of 6% sunflower oil has not affected the digestibility of nutrients and milk composition

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
