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: Evaluasi Penambahan Cassabio ke dalam Ransum terhadap Konsumsi dan Kecernaan Zat Makanan pada Anak Domba Lokal.
Abstrak: Problems that are faced in farming development in Indonesia are providing feed raw materials, these are due to its low quantity and quality, as well as expensive in its price. The availability of feed raw material is also limited by its competition with human needs which are in line with the increase in its population, and by its dependent on imported products. Utilisation of agricultural byproduct, and improving its quality with applied technology, can be used as alternatives to overcome the problems. Cassava waste (onggok) is a byproduct of cassava flour industry with an increase in its amount relating to the increase in cassava flour industry. However, its use is limited by its low crude protein content, but its energy content is high, then it can be used as energy source feed. Improving nutritive value of cassava byproduct can be done by solid substrate fermentation with Aspergillus niger which is mixed with urea and ammonium sulphate as inorganic nitrogen sources. The product is known as cassabio, but the optimal use of cassabio in a ration has not yet been determined. Therefore, the experiment is carried out to evaluate cassabio addition into rations of local lamb at growth phase on nutrient digestibility. The experiment was conducted using randomized block design with four treatments and three replications, local lambs were used as replications. The treatments applied were addition levels of cassabio into concentrate at 0% (P0), 20% (P1), 40% (P2), and 60% (P3). Variables measured were digestibilities of dry matter, organic matter, crude protein, crude fiber, ether extract, nitrogen free extract, total digestible nutrients (TDN) and digestible energy (DE). Data were analysed with analysis of variance (ANOVA) and differences among treatments were determined with Duncan test. The results showed that the use of cassabio up to 60% (P3) in rations for local lamb at growth phase produced the best results on variables measured (digestibility and consumption). The highest nutrient consumption and digestibilities were obtained at 568.65 gram/day and 76.25% for organic matter, 394.45 gram/day and 82.39% for nitrogen free extract, and 86.28 gram/day and 76.25% for crude protein. The conclusion of this research is the use cassabio up to 60% into concentrate given are safe and the best results in local lamb.

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.
