Judul: Penerapan open archive standard dan database caching pada pengembangan jaringan digital repository
Abstrak: Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH) is a method to perform metadata harvesting which does not depend upon particular platform. It is mainly caused by XML exertion in metadata exchange by using text based file with the result to be understood and accesible to all platform. OAI-PMH has Dublin Core metadata as standard element to describe information in regard to certain resource in the form of text, audio, video and audio video. In the implementation of OAI-PMH and Dublin Core, users can perform upload of digital archive in Data Provider so it can be given a metadata as Dublin Core standard. Thus, digital archive which had been approved to be publicized would have a global standarized metadata description, i.e. OAIPMH. The publication result of this digital archive collection then applicable to third party application, that is Service Provider, to perform harvesting process through internet network by using http protocol. Searching mechanism in Service Provider is not acting to search metadata directly which presents in Data Provider, yet it will search by using database caching method with Least Recently Used algorithm to search metadata within cache database in form of XML database which presents in Service Provider. The exertion of this database caching offer faster searching advantage. The whole advantage of this system is every institution can publish every digital archive by using standard of OAI-PMH and Dublin Core so other institution can utilize it by searching digital archive which had been publicized.

Judul: Modul Unggah Mandiri pada Repositori Institut Pertanian Bogor untuk Menghasilkan Metadata DSpace AIPS
Abstrak: Repositori institusi merupakan tempat penyimpanan online sebuah institusi untuk mengumpulkan, menyediakan, dan menyebarkan salinan digital temuan ilmiah dari institusi tersebut. Institut Pertanian Bogor memiliki repositori yang telah dikembangkan dan disempurnakan setiap tahunnya. Penelitian ini berfokus pada pengembangan modul unggah mandiri pada repositori IPB untuk menghasilkan metadata dengan format DSpace AIPS. Data yang digunakan dalam penelitian ini adalah data contoh skripsi, thesis, dan disertasi terbitan IPB. Metode yang digunakan adalah metode Waterfall, dikarenakan fungsi-fungsi dan alur proses yang sudah diketahui secara pasti. Tahapan-tahapan dalam metode ini adalah communication, planning, modelling, construction, dan testing. Keluaran dari modul ini adalah berupa file ZIP yang berisi file karya ilmiah dan metadata dari file tersebut. Metode Blackbox yang digunakan untuk pengujian modul ini menunjukkan seluruh fungsi pada modul Unggah Mandiri pada Repositori Institut Pertanian Bogor berhasil. Penelitian ini diharapkan dapat mempermudah pengguna repositori IPB untuk mengunggah dokumen karya ilmiah mereka, sehingga tentu saja akan meningkatkan kualitas repositori IPB itu sendiri.

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
