Judul: Performa Kelinci Potong Jantan Lokal Peranakan New Zealand White Yang Diberi Pakan Silase Atau Pelet Ransum Komplit
Abstrak: Complete ration silage has never been used in rabbits farm industry. Therefore, it is necessary to evaluate the quality in an attempt to reach feed security. The aim of this study was to compare and analize the effect of feeding complete ration silage on the performance of rabbits. This research used two diet treatments with six replications, each of which consisted of 6 rabbits with body weight of 1375.28 g ± 204.52. The treatments were complete ration pellet (R1) and complete ration silage (R2). The data obtained were analyzed using t-test. The result showed that the treatments significantly (P<0.01) affected feed consumption and body weight. The average feed consumption of New Zealand White was 824.49 ± 51.04 for complete ration pellet (R1) and 645.74 ± 19.16 for complete ration silage (R2). The average body weight for complete ration pellet (R1) was 1906.45±135.80 and it was 1663.15 ±110.07 for complete ration silage (R2). However, the treatments did not significantly influence daily weight gain, feed efficiency, carcass percentage and fat thighs. It can be concluded that complete ration silage has similar quality to complete ration pellet in terms of affecting performance of rabbits.

Abstrak: The aim of the study was to compare and analize the effect of complete feed with different combination I. zollingeriana leaves and Leucaena leucochepala leaves on rabbit performance. This research used a randomized block design, with five dietary treatments and four replications. The treatments were R0 (commercial pellet ration with 0% Leucaena leucochepala and 0% I. zollingeriana), R1 (complete pellet ration containing 30% Leucaena leucocephala and 0% I. zollingeriana, R2 (complete pellet ration containing 20% Leucaena leucocephala and 10% I. zollingeriana), R3 (complete pellet ration containing 10% Leucaena leucocephala and 20% I. zollingeriana), R4 (complete pellet ration containing 0% Leucaena leucocephala and 30% I. zollingeriana). Variables observed were feed intake, body weight gain, feed efficiency, fat content, carcass and non carcass weight, liver, heart, kidneys weights and Income Over Feed Cost. The data were analyzed with analysis of variance, and the differences among treatment were examined with Duncan Range Test. The results show that all complete pellet ration having the same effect in improving the performance of rabbits. Complete ration pellet with 30% Leucaena leucocephala and completed ration pellet with 30% I. zollingeriana had a tendency to derease the fat content compared with commercial pellet rations. It can be concluded that complete pellet ration containing I. zollingeriana and Leucaena leucochepala can be recommended as rabbit pellet.

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
