Judul: The Adding Cinnamaldehyde on Feed for Growth Performance of Carp (Cyprinus carpio).
Abstrak: Sinamaldehid merupakan polifenol hasil metabolit sekunder tanaman kayu manis yang berperan dalam metabolisme karbohidrat dan menghambat deposit lemak sehingga performa pertumbuhan dapat meningkat. Penelitian bertujuan menganalisis pengaruh penambahan sinamaldehid berbeda dosis pada pakan terhadap performa pertumbuhan ikan mas (Cyprinus carpio). Penelitian terdiri dari lima perlakuan dengan tiga kali ulangan pada setiap perlakuan. Dosis sinamaldehid yang digunakan pada penelitian ini yaitu 0 g kg-1, 0,5 g kg-1, 1 g kg-1, 1,5 g kg-1, dan 2 g kg-1. Ikan mas ukuran 8,82 ± 0,02 g dipelihara pada waring berukuran 100 x 100 x 200 cm3. Setiap waring diisi dua puluh ekor ikan mas (20 ekor/m2) dan diberi pakan perlakuan dua kali sehari secara at satiation selama 60 hari. Hasil penelitian menunjukkan bahwa pertumbuhan, efisiensi pakan, rasio efisiensi protein dan konversi pakan ikan mas yang diberi perlakuan sinamaldehid lebih baik dan berbeda nyata dibandingkan pakan tanpa penambahan sinamaldehid (P<0,05)., Cinnamaldehyde is a polyfenol from secondary metabolism of cinamon tree that functioned in carbohydrates metabolism and inhibit fat deposition that increase growth performance of carp (Cyprinus carpio). This research aim to analyze the impact of adding cinnamaldehyde with different dose on feed for growth performance of carp (Cyprinus carpio). This research contain five treatment with three replication on each treatment. The doses of cinnamaldehyde that used on this research is 0 g kg-1, 0,5 g kg-1, 1 g kg-1, 1,5 g kg-1, dan 2 g kg-1. Carp sized 8,82 ± 0,02 g were kept on dragnet sized 100 x 100 x 200 cm3. Each net filled with twenty carp (20 carp/m2) and get feeding two times a day in at satiation method for 60 days. The result of this research show’s that carp given by cinnamaldehyde treatment’s better and significantly different compared feed without cinnamaldehyde (P<0,05).

Judul: Pengaruh Pemberian Kayu Manis terhadap Kinerja Pertumbuhan dan Kualitas Daging Ikan Mas
Abstrak: This research was carried out to evaluate the effect of Cinnammomun burmanni as a supplement in the diet on the growth performance and flesh quality of the common carp Cyprinus carpio. A triplicate experiment was conducted using fish with an initial body weight of 7,88 ± 1,41 g. Fish were culture in aquaria 50x40x35 cm3 at a density of 10 fish/aquaria. Fish were fed on the diet contained either 0%,0,25%, 0,5%, 0,75%, or 1% respectively. Fish fed on the diet at satiation for 37 days. The results showed that the addition of Cinnammomun burmanni in the diet from 0% to 1% was insignificantly affected the growth and survival rate of fish. However, the addition of Cinnamomumn burmanni reduced feed efficiency. On the other hand, fish flavor and flesh texture were affected by the addition of Cinnamomun burmanni in the diet. The diet of 0,75% Cinnamomumn burmanni were the optimal result of this research with the sweet flavor and compact texture.

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
