Judul: Evaluasi Metode Pemberian Wafer Pakan yang Mengandung Daun Lamtoro (Leucaena leucocephala) pada Sapi Sumba Ongole.
Abstrak: Konsumsi daging sapi di Indonesia mengalami kenaikan setiap tahun namun produksi daging sapi masih rendah. Pola pemberian pakan yang tepat dengan suplementasi wafer daun lamtoro dapat meningkatkan produksi daging sapi. Tujuan dari penelitian ini adalah untuk mengevaluasi pengaruh pola pemberian dengan wafer pakan yang mengandung daun lamtoro terhadap performa sapi Sumba Ongole. Penelitian menggunakan Rancangan Acak Kelompok (RAK) 4 perlakuan dan 3 kelompok dengan 12 sapi Sumba Ongole. Perlakuan yang diberikan adalah P0 = Konsentrat [07.00 WIB] + Hijauan [09.00 WIB], P1 = Wafer [07.00 WIB] + Konsentrat [08.00 WIB] + Hijauan [09.00 WIB], P2 = Hijauan [07.00 WIB] + Wafer [08.00 WIB] + Konsentrat [09.00 WIB], P3 = Konsentrat [07.00 WIB] + Hijauan [08.00 WIB] + Wafer [09.00 WIB]. Hasil analisis statistik menunjukkan adanya pengaruh yang nyata (p<0.05) terhadap pertambahan bobot badan dan tidak berpengaruh nyata (p>0.05) terhadap konsumsi bahan kering, konsumsi protein kasar, konsumsi lemak kasar, IOFC dan efisiensi pakan. Pola P1 dan P3 mampu meningkatkan pertambahan bobot badan lebih tinggi yaitu sebesar 0,92 dan 0,91 kg/ekor/hari dibandingkan metode perlakuan lainya.

Judul: Efek Pemberian Wafer Suplemen Pakan Mengandung Daun Lamtoro (Leucaena Leucocephala) terhadap Konsumsi dan Kecernaan Pakan Domba Lokal
Abstrak: Feed is an important aspect for productivity of livestock. Low quality feed can reduce the productivity of the livestock, so wafer of fed supplement is one of alternative. Wafer lamtoro supplement is one of the feed processing products that have high nutritional value that can help increase the production of livestock. This research aimed to assess the effect of wafer fed supplement on nutrient consumption and digestibility of local sheep rations. This research used Randomized Block Design with 4 treatments and 3 blocks as replicate and used 12 heads of local sheep with initial body weight 24.54±10.51 kg. Treatments were P0 = basal diet + 0% wafer of feed supplement (control); P1 = basal diet + 5% wafer of feed supplement; P2 = basal diet + 10% wafer of feed supplement; P3 = basal diet + 15% wafer of feed supplement. The Results showed that wafer fed supplement had significantly effect (p<0.05) for nutrient consumption, crude protein digestibility, final body weight and feed efficiency but not significant for dry matter digestibility, organic matter digestibility and crude fiber digestibility

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
