Judul: Prevalensi Uretrostomi Perineum pada Kucing FLUTD di Papar, Sabah
Abstrak: Feline lower urinary tract disease (FLUTD) is a common disease that classified as an emergency case and need a quick treatment. This condition is usually effecting the urethra and bladder of the patients. This study aims to know the prevalence of perineal urethrostomy (PU) surgery in feline lower urinary tract disease (FLUTD) cats in SunRiz Animal Clinic, Papar, Sabah. Perineal urethrostomy (PU) is one of the surgical method that can be taken to treat urethral obstruction (UO) in cat. This surgery will remove the narrow part of the urethra and make a permanent urethral opening in the perineal region and help to decrease urethral obstruction (UO) in cats with complicated or recurrent obstructive feline lower urinary tract disease (FLUTD). This study was using 7 male cats and few reasons of doing PU were collected. 42.86% of the cats were going through a 3rd episode of FLUTD, while 71.43% of the cats were going through 2 catheterizations and having urinary tract infection (UTI) and kidney problem. The prevalence is depends on the blood and urine test results and the number of catheterization., Penyakit saluran kemih bawah pada kucing (FLUTD) adalah penyakit umum yang biasanya menyerang uretra dan kantong kemih dan membutuhkan perawatan segera. Penelitian ini bertujuan untuk mengetahui prevalensi operasi perineal urethrostomy (PU) pada kucing yang menderita FLUTD di Klinik Hewan SunRiz, Papar, Sabah. Uretrostomi perineum merupakan salah satu metode pembedahan yang dapat dilakukan untuk mengatasi obstruksi uretra pada kucing dengan cara mengangkat bagian sempit uretra dan membuat bukaan uretra permanen di daerah perineum. Penelitian ini menggunakan data sekunder yang diperoleh dari data operasi PU pada kasus FLUTD yang ditangani di Klinik Hewan SunRiz Papar, Sabah pada periode Juni 2020 sampai Februari 2021. Data dari 7 ekor kucing jantan dengan riwayat FLUTD dan obstruksi uretrostomi (UO) kambuhan yang diberikan operasi PU, digunakan. Data diperoleh dari rekam medis kesehatan pasien, tes hitung darah lengkap (CBC) dan tes urinalisis pasien. Semua data dianalisis secara deskriptif. 42,86% kucing mengalami FLUTD episode ketiga, yang mana telah mengalami kasus FLUTD kali ketiga. 71,43% kucing menjalani 2 kali kateterisasi dan mengalami infeksi saluran kemih (ISK) dan masalah ginjal. Prevalensinya tergantung dari hasil tes darah dan urin serta jumlah kateterisasi.

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
