Judul: Tinjauan laboratorik salmonellosis pada ungas yang dipelihara di Taman burung Taman Mini Indonesia Indah
Abstrak: Keadaan stress dan adanya hewan "carrier" salmonellosis dapat menyebabkan kejadian wabah salmonellosis pada suatu tempat konservasi satwa bangsa burung. Salmonellosis merupakan penyakit yang dapat ditularkan melalui makanan dan minuman yang terkontaminasi oleh kuman Salmonella. Kontaminasi kuman Salmonella ini berasal dari tinja burung penderita salmonellosis. Selain itu salmonellosis juga dapat ditularkan secara vertical yaitu lewat telur induk yang tertular. Kelembaban yang tinggi menguntungkan untuk kehidupan kuman Salmonella, sehingga umumnya kasus salmonellosis meningkat pada waktu musim hujan. Dari 30 sampel burung yang diperiksa, diketemukan 3 kasus positif salmonellosis yaitu terjadi pada Ayam hutan (hewan mati), Bebek Bali coklat dan Cendrawasih (hewan hidup) serta dapat diisolasi agen penyebabnya. Dalam penelitian ini berhasil diisolasi 40 isolat bakteri, yang terdiri dari Pseudomonas sp. 9 isolat (22,5%), Enterobacter aerogenes 6 isolat (15%), Edwardsiella tarda 6 isolat (15%), Proteus morganii 4 isolat (10%), Proteus vulgaris 4 isolat (10%), Hafnia alvei 3 isolat (7,5%), Escherichia coli 2 isolat (5%), Salmonella pullorum (5%), Salmonella gallinarum 1 isolat (2,5%), Proteus stuartii 1 isolat (2,5%). Pengendalian salmonellosis lebih dianjurkan dengan cara pencegahan daripada dengan cara pengobatan. Tindakan pencegahan yang dapat dilakukan antara lain ialah tempat pembibitan harus bebas salmonellosis berdasarkan uji serologis, dilakukan desinfeksi dan fumigasi tempat penetasan, kandang dan tempat pakan serta air minum dijaga kebersihannya setiap hari secara teratur serta makanan diberikan dalam keadaan segar dan bebas pencemaran kuman Salmonella…

Judul: Isolasi dan Identifikasi Salmonella enteritidis pada Telur Saluran Pencernaan dan Feses Ayam Ras dari Peternakan Ayam Petelur di Gunung Sindur Bogor
Abstrak: Salmonella became a major cause of food poisoning. Several types of Salmonella could infect chicken as well as pig, cattle, egg and other fresh product. Poultry could be infected by several types of this bacteria. Adult laying hens infected by Salmonella may carry the organisme in their small intestines and shed it in their faeces, which may lead to contamination of the eggshell surface, alternatively contamination of the laid egg may occur in vivo through the dessemination of the organisme to the egg following localization and colonization of the small intestine by Salmonella, that is by transovarian transmision. Total 6 hens, 12 eggs, and 22 samples of faeces were test. From this case, we must give more our atention to Salmonella so this study evaluated the prevalence of Salmonella in different hatchery by applying Bacteriological Analitycal Methode (BAM) for isolation and identification of this bacteria. The test shown that just faeces from Farm A which were contaminated by Salmonella. Test were not found all kind of species Salmonella in egg and gastrointestine

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
