Judul: Analisis Keberlanjutan Pemanfaatan Air Secara Langsung di Kawasan Taman Nasional Gunung Gede Pangrango Kabupaten Bogor
Abstrak: Water is common good and one of environmental services produced by forest. Gunung Gede Pangrango National Park (TNGGP) as Nature Preserve Area (KPA) has great potential of water resources over 548,960,480 m3/year (Rushayati 2006). Publics can use water resources without fee; though, the excessive and unwisely water uses can lead to decreasing its quality and quantity. Moreover, there are no technical rules which can be used as a guide to evaluate water utilization in KPA’s areas. The study objectives are to analyze mechanism of water utilization; to study sustainability status of water utilization; and to construct guidance in management of water utilization in TNGGP. This research was conducted in TNGGP focused to Bogor regency area. Data and facts were analyzed quantitatively and qualitatively in order to achieve the research objectives. Furthermore, Analytical Hierarchy Process (AHP) is used to determine weight of sustainability dimensions. The results reveal that the mechanism of water utilization is managed through partnership concept, yet it is not run very well due to there is no regulation at higher level that specifically regulates compensation mechanisms for environmental services. The direct water utilization in TNGGP for Bogor regency applies sustainability principle and its status is Sustainable with the sustainability index value 76.06%.

Judul: Analisis potensi sumberdaya Taman Nasional Gunung Gede Pangrango untuk keperluan perencanaan pengembangan daerah penyangga
Abstrak: Di daerah tropika perhatian utama sedang mengarah pada pelestarian ekosistem hutan. Indonesia sebagai pemilik hutan hujan tropika terbesar ketiga di dunia (MacKinnon, et. al., 1990) juga menyadari pentingnya melestarikan dan mempertahankan sumberdaya yang dimilikinya. Taman Nasional Gunung Gede Pangrango di Jawa Barat merupakan salah satu kawasan pelestarian alam ekosistem hutan hujan tropis pegunungan. Pengelolaan dan pengembangan Taman Nasional Gunung Gede Pangrango banyak mengalami gangguan dan tekanan dari masyarakat, terutama dari masyarakat yang tinggal di sekitar taman nasional tersebut (Program Pengembangan Taman Nasional Gunung Gede Pangrango Pelita VI, 1994). Untuk itu perlu adanya strategi pengembangan daerah. penyangga untuk mengurangi gangguan langsung terhadap kawasan yang dilindungi dan kawasan yang penggunaan tanahnya bertentangan dengan misi dan tujuan pelestarian alam Taman Nasional Gunung Gede Pangrango. Untuk menyusun strategi pengembangan dan pengelolaan daerah penyangga tersebut di atas perlu dilakukan inventarisasi sumberdaya yang terdapat di dalam kawasan dan perlunya mengkaji kondisi sosial ekonomi masyarakat sekitar.

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
