Judul: Penambahan Minyak Biji Bunga Matahari terhadap Profil Darah Domba Garut Betina pada Status Faal Berbeda
Abstrak: Minyak biji bunga matahari salah satu lemak yang dapat digunakan sebagai sumber energi. Penelitian dilakukan untuk melihat pengaruh pemberian minyak biji bunga matahari pada 8 domba garut betina calon induk dengan bobot badan 22.12±1.69 kg saat prakawin, bunting, dan laktasi dengan rancangan acak lengkap pola tersarang (nested design). Status faal (prakawin, bunting, dan laktasi) tersarang pada 2 perlakuan, tanpa minyak biji bunga matahari dan dengan penambahan 4% minyak biji bunga matahari pada ransum dengan 4 ulangan. Parameter yang diamati yaitu konsumsi bahan kering, protein kasar, lemak kasar, dan profil darah (hemoglobin, hematokrit, eritrosit, leukosit, Mean corpuscular volume (MCV), Mean corpuscular hemoglobin concentration (MCHC), dan deferensiasi leukosit). Penambahan minyak biji bunga matahari 4% dalam ransum tidak mempengaruhi profil darah, pada status bunting dan laktasi jumlah eritrosit dan persentase basofil cendrung meningkat. Konsumsi bahan kering, protein kasar, dan lemak kasar domba bunting dan laktasi sangat nyata lebih tinggi dari domba prakawin. Konsumsi lemak kasar pada domba yang diberikan 4% minyak biji bunga matahari lebih nyata lebih tinggi dari kontrol. Kesimpulan dari penelitian ini penambahan minyak biji bunga matahari 4% dalam ransum tidak mengganggu hematologi domba induk saat prakawin, bunting, dan laktasi.

Judul: Penambahan Minyak Biji Bunga Matahari Terhadap Profil Darah Domba Garut Betina pada Status Faal Berbeda
Abstrak: Sunflower seed oil is one of fat that can be used as an energy sources. The study was conducted to evaluate the effect of sunflower seed oil in premating, pregnant and lactation in eight Garut ewes with body weight 22.12±1.69 kg used in completely randomized nested design. The status of physiology (premating, pregnant, and lactation) nested in two treatment, control (without sunflower seed oil) and 4% sunflower oil addition in the ration with four replications. The parameters observed were dry matter, crude protein, crude fat intake, and blood profiles (haemoglobin, hematocrit, erythrocytes, leukocytes, MCV, MCHC, and leukocyte differentiation). Result showed that the addition of 4% sunflower seed oil was not affected to blood hematology, but the status of pregnant and lactation tends to increase erythrocytes and percentage of basophils. Dry matter, crude protein, and crude fat intake in pregnant and lactating ewes were higher than premating. Crude fat intake in 4% sunflower seed oil treatment was higher than control. It was concluded that the addition of 4% sunflower seed oil was not interfere blood hematology in premating, pregnant, and lactation ewes.

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
