Judul: Effect of electrolyte drink made from palm sugar (Arenga pinnatamerr) for lamb transportation
Abstrak: Long distance of sheep transportation can cause stress. In general, the losses caused by poor handled include physiological, phychological and economical factor. The aims of study was to observe the effect of initial information isotonic drink made from Palm Sugar (Arenga PinnataMerr),and the effect ofisotonic drinks best on the sheep transportation physiological responses, body weight shrinkage, feed intake reduction and changing in blood profiles. A total of 20 local garut sheep under 1 years old were trasported for 120 km distance and took aproximatly ±8 hours. The study used CRD (completely randomized design) consisted of three traetments with 5 replicates. The treatments were the time of offering isotonic drink as follows:P1= control (without isotonic drink), P2= offering isotonic drink an hour before trasnsportation, P3= offering isotonic drink after after transportation, and P4= offering isotonic drink before and after transportation. The results showed that on body temperature, heart rate, respiration rate. Shrinkage percentage of body weight, feed consumption and the value of neutrophils (P <0.05). Body weight shrinkage percentage, feed intake reduction and the value of neutrophils (P<0.05). Average body weight lowest shrinkage P3 (5.73%) and the highest P1(10,05%), the lowest decrease in feed consumption P2 (20%) P.1 highest (42.6%) and an increase in the value of neutrophils P3 (51.78%) and the highest P1(67.76%). It was concluded of this study was isotonic drink is the provision of an isotonic drink made from palm sugar with isotonic drinks granting post-transport P3 showed positive results for body weight and value depreciation blood neutrophils, but for best consumption reduction obtained P2. However, effect of isotonic drinks have not been able to provide the restorative effects of stress in a short time.

Judul: The effects of sucrose supplementation, insulin injection, and resting period prior to slaughtering on meat quality in sheep exposed to stressful transportation
Abstrak: An experiment was conducted to study the effects of sucrose supplementation, insulin injection, and resting period prior to slaughtering on meat quality in sheep exposed to stressf1.11tr ansportation. FiRy four female local sheep (10 to 12 months of age) with weight ranging from I4 to 17 kg. The experimental sheep were assigned into a completely randomized design with a 2x3~3 factorial arrangement with 3 replications. The first factor was sucrose supplementation wih 2 leveb (0 and 6 @g body weight). The second factor was insulin injection afkr transportation with 3 levels (0, 0,3 and 0-6 ILTlkgBW). The third factor was the duration of resting perid with 3 levels (2,4 and 6 h prior to slaughtering). Parameters measured were rectal temperature and heart rate, live weight, carcass percentage, blood glucose concentration, meat glycogen concentration, meat lactate concentration, meat pH, water holding capacity, meat tenderness, cooking loss and meat color. The results of the experiment indicated that sheep supplemented with sucrose after transportation had higher meat glycogen and lactate concentration but lower meat pH and cooking loss. Insulin injection decreased blood glucose concentration but increased meat glycogen and lactate concentration. The longer the resting period prior to slaughtering the lower the live weight but the higher carcass percentage. B l d glucose concentration decreased with the increased resting period prior to slaughtering. Water holding capacity, meat tenderness and meat colour did nor show significant differences. It was concluded that sucrose supplementation, insulin injection, and resting period prior to slaughtering in sheep exposed to stressful transportation could improve meat quality.

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
