Judul: Strategi Hubungan Masyarakat Dalam Meningkatkan Citra Organisasi Nirlaba (Kasus: World Wide Fund For Nature - Indonesia)
Abstrak: Organisasi nirlaba yang bergerak pada isu lingkungan sudah semakin dikenal banyak orang. Keberhasilan yang diupayakan organisasi nirlaba berupa peningkatan citra positif diperoleh dari hubungan media. Penelitian ini bertujuan untuk menganalisis strategi Hubungan Masyarakat (Humas) WWF-Indonesia dalam meningkatkan citra organisasi. Penelitian ini dilaksanakan dengan pendekatan kuantitatif dan pendekatan kualitatif. Metode penelitian yang digunakan ialah survai pada dua organisasi kemahasiswaan Institut Pertanian Bogor yang pernah bekerjasama dengan WWF-Indonesia, yaitu Fisheries Diving Club (FDC) dan Himpunan Mahasiswa Peminat Ilmu-Ilmu Komunikasi dan Pengembangan Masyarakat (HIMASIERA). Analisis data meliputi uji Rank Spearman dan Chi Square digunakan untuk melihat hubungan antara strategi Humas dengan citra organisasi nirlaba. Hasil yang diperoleh dari penelitian, yaitu: 1) ada hubungan antara karakteristik individu dengan citra perusahaan yang terbentuk; 2) ada hubungan antara antara aktivitas Humas yang dilakukan dengan citra perusahaan.

Judul: Strategi Public Relations dalam Meningkatkan Citra Sentulfresh Education Program
Abstrak: Public Relations have implemented communication strategies to increase the image. Communication strategies is achieved through three of approaches, such as educative and persuasive approach, public relations social responsibility approach, and cooperation approach. This study using a quantitative approach that supported by qualitative data, and SWOT analyze to determine the strategies which must to implemented through the relationships between the characteristics of the tourists characteristics and Public Relations activity with the image of Sentulfresh Education Farm which is the result of the assessment of the constituent visitors tour. Statistical analysis showed that the variables of education level, frequency arrival, frequency of PR activities and strength of the message associated with the image of Sentulfresh Education Farm. SWOT analysis calculations show that the Public Relations Education Farm Sentulfresh must aggressive strategy in order to optimize the strengths and to utilize the opportunities

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
