Judul: Formulasi Strategi Pengelolaan Sungai Batanghari di Kota Jambi
Abstrak: Air merupakan sumber daya alam yang memenuhi hajat hidup orang banyak sehingga perlu dilindungi agar dapat tetap bermanfaat bagi hidup dan kehidupan manusia serta makhluk hidup lainnya. Namun demikian, saat ini masalah air di Indonesia merupakan permasalahan yang kronik dan pelik, mulai dari peristiwa banjir sampai kekeringan. Kegiatan manusia yang mengunakan sumber daya air akan berpotensi menimbulkan dampak negatif berupa pencemaran yang dapat mengancam ketersediaan air, daya guna, daya dukung, daya tampung dan produktivitasnya. Tekanan terhadap sumber daya perairan darat dapat terjadi pada badan air itu sendiri atau terhadap lingkungannya (daerah aliran sungai). Tekanan ini dalam bentuk limbah yang masuk ke dalam badan air baik yang berasal dari domestik, industri, maupun pertanian. Sedangkan tekanan yang terjadi pada daerah aliran sungai berupa sedimen yang merupakan hasil erosi pada daerah pertanian. Selain itu, perubahan penggunaan lahan dapat mengakibatkan terganggunya siklus air (banjir dan kekeringan). Sungai Batanghari merupakan sungai utama dan sumber air bersih bagi masyarakat di Kota Jambi. Pencemaran yang terjadi di perairan Sungai Batanghari akibat aktivitas industri karet remah telah meresahkan masyarakat Kota Jambi akan kondisi kualitas perairannya. Untuk itu perlu dilakukan pengelolaan perairan Sungai Batanghari yang memperhatikan keberlanjutan ekosistem lingkunganya.

Judul: Strategi pengembangan kota Jambi menuju Riverfront city
Abstrak: The development of social, culture and economic at Jambi City is inseparable with Batanghari River. The existence of Batanghari river plays important role in economic development at Jambi City. The aims of this research were to identify the potential of Batanghari River as well as its problems, to identify and analyze stakeholders that have roles in the development of Jambi City towards a riverfront city, and to formulate the strategy of the development of Jambi City towards a riverfront city. The results of this research showed that Batanghari River has potentials to be developed as a riverfront city. The development is devided into three zone including natural zone, semi-natural zone, and multipurpose zone. There were twenty one stakeholders that have roles in the development of Batanghari River. The hierarcy strategies of the development of Jambi City towards a riverfront city are as follows emproving the coordination among the stakeholders, community development, law enforcement, making perfect the watershed of Batanghari River, revitalizing of Batanghari River and developing the eco-industrial park.

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
