Judul: Pemberian Cassabio dalam Konsentrat terhadap Status Fisiologi, Profil Hematologi dan Urea Darah Domba Ekor Gemuk
Abstrak: Aim of the research was to study the effect of cassabio in the diet on physiological status, haematological profile and blood urea nitrogen in thin tail sheep. This research divided into four treatments with three replications. The treatments were R0: control feed without cassabio, R1: contained 20% commercial feed cassabio, R2: contained 40% commercial feed cassabio, R3: contained 60% commercial feed cassabio. The statistics analysis used were in time randomized block design for physiological status and randomized block design for hematological profile and blood urea nitrogen. Based on the results showed that the utilization of cassabio has not significant effect on rectal temperature and heart rate but significant effect to time difference in the morning, afternoon, and evening (P<0.05). the use of cassabio in all levels increased significantly (P <0.05) on respiration rate in whole day, while those cassabio utilization has not significant effect on hemoglobin, erythrocytes, leukocytes, differentiation of leukocytes and blood urea nitrogen concentration.

Judul: Efek Penambahan Cassabio dalam Ransum terhadap Performa Anak Domba Lokal
Abstrak: Cassava pulp isone of the tapioca industry by-product that can be used as animal feed. However, the quality of cassava pulp is relatively low due to its low protein and high crude fiber content. Cassava pulp with addition of zeolite, urea, ammonium sulphate, that fermented by Aspergillus niger produced the product that called cassabio. The experiment of using cassabio on broiler have been done. However, there is no experiment of using cassabio on performance of ruminants. The objective of this research is to evaluate the effect of levels cassabio in concentrate on performance of local lamb. The experiments design was randomized block design with four treatments and three replications, and local lambs were used as replications. The treatments were addition levels of cassabio into concentrate at levels of 0% (P0), 20% (P1), 40% (P2), and 60% (P3). Variables that measured were feed consumption, average body weight gain, and feed efficiency. Data were analysed by analysis of variance (ANOVA)and differences among treatments were determined by Duncan test. The result showed that the cassabio levels P0, P1, P2, dan P3 for BWG was76.19; 81.43; 84.29; and 96.90 g head-1 day-1respectively; for intake was 444.34; 463.13; 483.03 and 493.52 g head-1 day-1respectively; feed efficiency was 0.17; 0.18; 0.17; and 0.20 respectively. The conclusion of the research was using cassabio up to 60% (P3) in concentrate produced the good results without negative effect on local lamb performance.

Abstrak: Mencari akarMakar polinomial dengan menggunakan algoritma Weyt. Algoritma WeyJ merupakan algoritma rekursif yang proses kerjanya dapat diana10gkan dengan algoritma Bisection. Karena algoritma Weyl bergerak dalam bidang kompleks maka memerlukan nilai awal hempa bujur sangkar. Dalam proses penyempitan bujur sangkar tersebut algoritma Weyl memerlukan algorittna Turan untuk menentukan jarak antara suatu titik dengan akar polinomial yang terdekat dengan titik tersebut. Karena apabiJa jarak tersebut temyata lebih hesar dari Yl panjang diagonal bujur sangkar yang diamati maka bujur sangkar tersebut tidak memuat satu pun akar polinomial. Untuk seJanjutnya bujur sangkar tersebut diabaikan. Sebaliknya apabila jarak yang diperoleh lebih keeil dari \6 panjang diagonal bujur sangkar yang diamati, maka bujur sangkar tersebut yang akan diperkeciL
