Judul: Pengelolaan perkebunan sagu (Metroxylon spp) di PT. National Sago Prima, Selat Panjang, Riau: seleksi bibit sagu berdasarkan jenis, tinggi pohon induk dan bobot bibit sagu terhadap pertumbuhan bibit sagu di persemaian
Abstrak: Sago nursery is a special factor that performed during the internship activities at PT. National Sago Prima, Selat Panjang, Riau. The experiment was conducted to obtain information in a nursery on the effects of this type of sago, height of mother plant sago and weight of sucker. The type of sago used was spiny sago (S1) and sago without spiny (S2). Height of mother plant used was 3.3 m - 4.6 m (T1), 4.6 m - 6.6 m (T2), more than 6.6 m (T3) and mother plant that have been harvested (T4). Sucker Weight used was 0,5 kg – 1,5 kg (B1), 2 kg – 3 kg (B2) dan 3,5 kg – 4,5 kg (B3). The results shown sago without spiny is better than spiny sago, height of mother plant is not effect significantly and sucker weight 3,5 kg – 4,5 kg is better than two other sucker weight. During the internship activities, sago cultivation activities conducted to obtain primary data. Secondary data were obtained by conducting interviews, discussions and reading of literature contained in the company.

Judul: Pengelolaan sagu (Metroxylon spp.)  Di PT National sago Prima, selat panjang Kab. Kepulauan Meranti, Riau, dengan aspek khusus pertumbuhan bibit di lapang
Abstrak: This intenship was held in Nasional Sago Prima company, Selat Panjang, Riau from February to June 2011. The Method are direct for getting primary dara and indirect for secondary data. Secondary data takes from technique activity in tthe field and the research. The experiment was conducted to get more information on the effect sucker weight and time after nusery to to sucker growth in plantation are. The treatment will be tested sucker growth with the different weight and age of sucker in raft nursery system. The first treatment on sucker 2-4 kg (BI) and 4-8 kg (B2), teh second treatment on sucker is 2 weeks after nussery (P1), 4 weeks (P2), 8 weeka (P3) and 12 weeks (P4), the result shown treatment on 2-4 kg (B1) is better than nursey was significant different in presentation survival rate bt in vegatative growth haven't significantly difference. The sucker 123 weeks after nursery was the best sucker age to the vegetative growth of suckers.

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
