Judul: Performance Of Beef Cattle Fed Herbal Mineral Block Containing Black Soldier Fly Larvae Meal, Turmeric, And Microminerals
Abstrak: Penelitian ini bertujuan menganalisis pengaruh herbal mineral block (HMB) mengandung tepung deffated larva Black Soldier Fly (BSF), kunyit, dan mineral mikro terhadap performa sapi meliputi konsumsi pakan, pertambahan bobot badan harian, dan efisiensi pakan. Selama 30 hari, 12 sapi pedaging dengan usia rata-rata 12 bulan dan bobot badan 326,25 ± 54,20 kg dibagi menjadi 2 perlakuan dan 6 kelompok sebagai ulangan menggunakan rancangan acak kelompok (RAK) berdasarkan bobot badan awal dengan perlakuan, yaitu P0 = ransum tanpa pemberian HMB (kontrol) dan P1 = ransum dengan pemberian HMB. Variabel yang diamati adalah konsumsi pakan, konsumsi HMB, pertambahan bobot badan harian (PBBH), dan efisiensi pakan. Data yang diperoleh dianalisis menggunakan Analysis of Covariance (ANCOVA) dalam software IBM SPSS 25. Hasil penelitian menunjukkan bahwa pemberian HMB selama 30 hari tidak berpengaruh nyata terhadap konsumsi pakan, pertambahan bobot harian dan efisiensi pakan. Simpulan dari penelitian ini, pemberian suplemen HMB belum memberi pengaruh terhadap performa sapi pada jangka pendek (30 hari)., The aim of this research was to analyze the feed intake, growth, and feed efficiency of cattle fed with Herbal Mineral Block (HMB) containing Defatted Black Soldier Fly (BSF) larvae meal, turmeric, and minerals. Over 30 days, 12 cattle with an average age of 12 months and weight of 326.25 ± 54,20 kg were divided into 2 treatments and 6 groups with a randomized block design. Cattle was grouped based on initial body weight with the following treatments, P0 = ration without HMB (control) and P1 = ration with HMB. The parameters measured were feed and HMB intake, average daily gain, and feed efficiency. The data obtained were analyzed using Analysis of Covariance (ANCOVA) on IBM SPSS 25. Results showed that supplementation of HMB within 30 days did not yet affects feed intake, average daily gain, and feed efficiency. It was concluded that HMB supplementation in a short time (30 days) did not yet improve the performance of the cattle.

Judul: Blood Profile and Mineral Status of Dorper sheep Fed Herbal Mineral Block (HMB)
Abstrak: Penelitian ini bertujuan menganalisis pengaruh suplementasi herbal mineral blok (HMB) mengandung tepung larva black soldier fly (BSF), tepung kunyit, dan mineral mikro terhadap profil darah dan status mineral darah. Penelitian menggunakan 10 ekor domba dorper jantan dengan rata-rata berat awal 17,49±1,65 kg yang ditempatkan pada kandang individu. Perlakuan yang digunakan yaitu P0 = pakan kontrol tanpa suplementasi HMB dan P1 = pakan kontrol dengan suplementasi HMB selama 56 hari. Parameter yang diukur adalah profil hematologi dan status mineral darah (Ca, P). Data dianalisis menggunakan Independent Sample T-Test. Hasil penelitian menunjukkan suplementasi HMB selama 56 hari tidak memberikan pengaruh yang nyata (P>0,05) terhadap profil hematologi, konsumsi nutrien dan status mineral darah (Ca dan P) pada domba dorper jantan. Pemberian HMB selama 56 hari belum mempengaruhi konsumsi nutrien, profil darah dan status mineral darah domba., This research was aimed to analyze the effect of herbal mineral block (HMB) containing black soldier fly (BSF) larvae meal, turmeric meal, and micro mineral supplementation on the hematology and was mineral status of lambs. This research used 10 lambs (initial weight of 17,49±1,65 kg) placed in an individual cage. The treatments used were P0 = ration control without HMB supplementation (control) and P1 = ration control with HMB supplementation for 56 days. The parameter measured were hematology and plasma mineral status of blood (Ca and P). Data were analyzed using independent sample T-test. Results of the study showed that HMB supplementation for 56 days had no significant effect on hematology profile, nutrient intake and plasma mineral status (Ca and P). It was concluded HMB supplementation for 56 days had no effect on nutrient intake, hematology, and blood mineral status of lambs.?

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
