Judul: Provision of Flushing Rations at Different Phases of the Performance of the Ewes and Pre-weaning Lambs
Abstrak: Penelitian bertujuan menganalisis pengaruh pemberian ransum flushing pada fase berbeda terhadap performa induk dan anak domba pra-sapih. Penelitian menggunakan 12 ekor domba betina beranak kedua dan 18 ekor anak domba. Rancangan acak kelompok (RAK) 4 x 3 dengan perlakuan P1 = tanpa flushing, P2 = flushing sebelum dan sesudah kawin, P3 = flushing sebelum dan setelah kawin serta tengah kebuntingan, P4 = flushing sebelum dan setelah kawin, tengah serta akhir kebuntingan. Peubah yang diukur adalah konsumsi nutrien, bobot induk beranak, pertambahan bobot badan induk beranak, bobot lahir, bobot sapih, mortalitas dan pertambahan bobot badan harian anak pra-sapih. Data dianalisis dengan analisis ragam dan uji lanjut Duncan. Analisis deskriptif digunakan untuk mengetahui tingkat mortalitas. Pemberian ransum flushing pada fase berbeda nyata meningkatkan konsumsi lemak kasar dan PBHH anak umur 14 hari (P<0.05), namun, tidak berpengaruh nyata terhadap bobot induk pasca beranak, PBB induk beranak, bobot lahir, dan bobot sapih anak domba (P>0.05). Dapat disimpulkan bahwa pemberian ransum flushing P4 mampu meningkatkan konsumsi lemak kasar induk domba dan PBBH anak umur 14 hari., The aim of the study was to analyze the effect of giving flushing rations at different phases of the performance of pre-weaned broods and lambs. The study used 12 ewe lambs with second lambs and 18 lambs. Randomized block design (RBD) 4 x 3 with treatment P1 = no flushing, P2 = flushing before and after mating, P3 = flushing before and after mating and in the middle of pregnancy, P4 = flushing before and after mating, middle and end of pregnancy. The variables measured were nutrient consumption, calf weight, calf body weight gain, birth weight, weaning weight, mortality and daily body weight gain of pre-weaning cubs. Data were analyzed by analysis of variance and Duncan's further test. Descriptive analysis was used to determine the level of mortality. Provision of flushing rations in different phases significantly increased crude fat consumption and daily body weight gain of lambs aged 14 days (P<0.05), however, did not significantly affect post-calving brood weight, post-calving brood weight gain, birth weight, and body weight of weaning lambs (P>0.05). In conclusion, P4 was able to increase the consumption of crude fat of the ewes and the daily body weight gain of the lambs aged 14 days.

Judul: The Effect of Different Flushing Management on Local Ewes Production Perfromance During Pregnancy
Abstrak: Penelitian ini bertujuan menganalisis pengaruh manajemen flushing yang berbeda terhadap performa produksi induk domba lokal selama bunting. Penelitian ini menggunakan 16 domba betina laktasi kedua dengan rata-rata bobotnya 30,06 ± 6,20 kg dan ditempatkan di kandang individu. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 4 kelompok. Perlakuan terdiri atas P1 = tanpa flushing, P2 = flushing sebelum dan setelah dikawinkan, P3= flushing sebelum dan setelah dikawinkan, serta di tengah kebuntingan, P4 = flushing sebelum dan setelah dikawinkan, ditengah dan diakhir kebuntingan. Rasio hijauan : konsentrat dalam ransum adalah 30 : 70 % berdasarkan bahan kering. Peubah yang diamati meliputi konsumsi nutrien, body condition score (BCS), pertambahan bobot badan harian (PBBH), efisiensi pemanfaatan pakan, dan income over feed cost (IOFC). Data dianalisis dengan ANOVA dan dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P>0,05) terhadap konsumsi bahan kering, konsumsi protein kasar, konsumsi serat kasar, konsumsi Beta-N, BCS, PBBH, efisiensi pemanfaatan pakan, dan nilai IOFC. Manajemen flushing berpengaruh nyata (P<0,05) terhadap konsumsi lemak kasar, konsumsi total digestible nutrient (TDN), dan perubahan nilai BCS sebelum dan setelah flushing. Disimpulkan bahwa manajemen flushing yang berbeda dengan penambahan minyak ikan lemuru sebelum dan setelah kawin, ditengah, dan diakhir kebuntingan mampu meningkatkan dan memperbaiki performa produksi induk domba lokal serta menghasilkan keuntungan yang paling tinggi., The aim of this research was to analyze the effect of different flushing management on local ewes production perfromance during pregnancy. This research used 16 second lactating local ewes, average weight was 30,06 ± 6,20 kg and placed in individual cages. This research used a Randomized Block Design (RBD) with 4 treatments and 4 replications. P1 = without flushing, P2 = flushing during before and after matting, P3 = flushing during before and after matting, and in the middle of pregnancy, P4 = flushing during before and after matting, in the middle and end of pregnancy. Ratio forages and concentrate in the ration were, 30:70 % dry matter basis. The parameter observed were nutient consumption, body condition score (BCS), body weight gain (BWG), feed utilization efficiency, and income over feed cost (IOFC). The data were analyzed using ANOVA and Duncan test. The results showed that the treatment did not significant effect (P>0,05) on consumption of dry matter, consumption of crude protein, consumption of crude fiber, consumption of Beta-N, BCS, BWG, feed utilization efficiency, and IOFC. Flushing management had significant effect (P<0,05) on consumption of crude fat, consumtion of total digestible nutrient (TDN), and difference of BCS before and after flushing. It was concluded that different flushing management with the addition of lemuru fish oil before and after matting, in the middle and end of pregnancy increased and improved production perfromance of local ewes, and produced the highest profit.

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
