Judul: Mapping Body Surface Temperature  Pattern of Anoa in Captive Habitat by Using Infrared Thermal Camera
Abstrak: Pengukuran tanda vital pada satwa liar memiliki kendala lebih besar daripada ternak, oleh karena itu tenaga medis veteriner membutuhkan instrumen noninvasif dan jarak jauh untuk akuisisi data medis. Kamera termal inframerah dapat menjadi solusi terbaik untuk masalah tersebut. Gelombang inframerah dapat dimanfaatkan untuk mengukur suhu tubuh satwa liar dari kejauhan. Penelitian ini bertujuan mempelajari potensi suhu permukaan anoa (Bubalus depressicornis), serta efektivitas kamera termal inframerah pada pagi dan siang hari. Pengambilan data citra termal dilakukan pada pukul 08.00-09.00 WIB dan 12.00-13.00 WIB selama lima hari. Pengambilan citra termal dilakukan pada lima regio yaitu mata, moncong, pipi, toraks dan abdomen. Hasil rata-rata suhu permukaan pada pagi hari selama lima hari yaitu kepala ...dst, Measurement of vital signs in wild animals has greater constraints than livestock, therefore veterinary medical personnel need noninvasive and remote instruments for medical data acquisition. Infrared thermal camera can be the best solution for the problem. Infrared waves can be used to measure the body temperature of wildlife from a distance. This study aims to study the potential surface temperature of anoa (Bubalus depressicornis), as well as the effectiveness of infrared thermal cameras in morning and noon time. Thermal image data was collected at 08.00-09.00 and 12.00-13.00 (GMT+7) for five days. Thermal images were taken in five regions, namely eyes, snout, cheeks, thorax and abdomen. The results of the average surface temperature in the morning for five days are head ... dst

Judul: Giraffe (Giraffa camelopardalis) Surface Temperature Pattern in Wildlife Park Ragunan Using Infrared Thermal Camera Image
Abstrak: Kamera termal inframerah merupakan alat untuk mengukur suhu permukaan dengan metode non-invasif, cepat, murah, dan efisien terutama untuk satwa liar. Kamera termal inframerah membantu mengidentifikasi proses fisiologis pada hewan melalui pengukuran suhu permukaan tubuh hewan. Penelitian ini bertujuan mengukur nilai suhu permukaan normal jerapah pada berbagai regio tubuh menggunakan citra kamera termal inframerah serta menentukan regio yang paling dekat untuk memperkirakan suhu inti tubuh jerapah. Tiga jerapah digunakan sebagai hewan coba. Pengambilan data citra termal selama 5 hari dilakukan pada rentang waktu pagi hari pukul ±09:00 dan siang hari pukul ±12:00 WIB. Regio yang diukur meliputi regio mata, pipi, hidung, thorax, dan abdomen dengan nilai rata-rata suhu permukaan sesi pagi secara berurut yaitu 35,54ºC; 34,77ºC; 32,19ºC; 32,66ºC; 32,77ºC; dan sesi siang 36,39ºC; 34,61ºC; 34,49ºC; 35,00ºC; 34,47ºC. Suhu regio mata memiliki suhu paling tinggi diantara regio pipi, hidung, thorax, dan abdomen. Suhu permukaan dipengaruhi oleh suhu inti, suhu lingkungan, kelembapan, dan regulasi pembuluh darah. Regio terbaik untuk memperkirakan suhu inti tubuh adalah regio mata. Regio mata memiliki nilai paling dekat dengan suhu inti tubuh jerapah., Infrared thermal camera is a tool for measuring surface temperature with a non-invasive, fast, low-cost, and efficient method, especially for wildlife. Infrared thermal cameras help identify physiological processes in animals by measuring the surface temperature of the animal's body. This study aims to determine the normal surface temperature and the closest region to the core body temperature of giraffes using infrared thermal camera images. Three giraffes were used as experimental animals. Thermal image data retrieval for 5 days was carried out in the morning at ±09:00 and in the afternoon at ±12:00 WIB. The result showed that the average surface regions temperature of eye, cheek, nose, thorax, and abdomen in the morning session in five days were 35,54ºC; 34,77ºC; 32,19ºC; 32,66ºC; 32,77ºC; and in the afternoon session were 36,39ºC; 34,61ºC; 34,49ºC; 35,00ºC; 34,47ºC respectively. The temperature of the eye region has the highest temperature among the cheek, nose, thorax, and abdomen regions. Surface temperature is affected by core temperature, ambient temperature, humidity, and vascular regulation. The best region for estimating core body temperature is the eye region. The eye region has the closest value to the giraffe's core body temperature.

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
