Judul: Legality and Institutional Development of Packaged Drinking Water Products (Case Study of SUA Bening TIN IPB)
Abstrak: SUA Bening merupakan perusahaan penyedia air minum di bawah Departemen TIN IPB. Aspek legalitas yang belum sepenuhnya ada pada SUA Bening, sehingga membatasi penjualan dan melanggar peraturan dalam perdagangan. Penelitian ini bertujuan merancang pembuatan legalitas berupa izin edar, wajib SNI dan sertifikasi halal pada AMDK SUA Bening. Tahap penelitian menggunakan 2 jenis penelitian, yaitu penelitian lapangan (field research) dan penelitian kepustakaan (library research). Melalui penelitian lapangan didapatkan beberapa usulan, yaitu jenis pelaku usaha yang sesuai dengan kondisi SUA Bening, pembuatan persyaratan dan dokumen pendaftaran legalitas (izin edar, wajib SNI dan sertifikasi halal) dan penyediaan dokumen pendaftaran sertifikasi halal., SUA Bening is a drinking water supply company under the TIN IPB Department. Legality that does not yet at all exist in SUA Bening limits sales and violates trade regulations. This study aims to design the manufacture of legality in the form of Circulation Permits, Mandatory SNI and Halal Certification on SUA Bening AMDK. The research phase uses 2 types of research, namely field research and library research. Through field research, several proposals were obtained, namely the type of business actor in accordance with the conditions of SUA Bening, preparation of requirements and legality registration documents (Marketing Permit, Mandatory SNI and Halal Certification) and provision of Halal Certification registration documents.

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
