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: Increasing meat flavor quality of lamb supplemented with sucrose and injected with insulin under different recovery times following transportation
Abstrak: An experiment was conducted in order to study the influence of sucrose supplementation and insulin injection under different recovery times following transportation on the flavor quality of lamb. Fifty four female local lamb (10 to 12 months of age) with weight ranging from 14 to 17 kg were used in the experiment. The experimental lamb were assigned into a completely randomized design with a 2x3x3 factorial arrangement with 3 replications. The first factor was sucrose supplementation with 2 levels (0 and 6 g/kg body weight). The second factor was insulin injection after transportation with 3 levels (0, 0.3, and 0.6 IU). The third factor was the duration of recovery times with 3 levels (2, 4, and 6 h prior to slaughtering).

Judul: Graf Pembagi-Nol Planar dan Tak-Planar
Abstrak: Graf pembagi-nol adalah suatu graf yang dibentuk dari himpunan pembaginol pada ring. Graf pembagi-nol terdiri atas himpunan simpul yang merupakan elemen-elemen pembagi-nol dari ring, serta dua simpul adjacent jika dan hanya jika hasil kalinya sama dengan nol. Graf pembagi-nol dapat digambarkan dalam sebuah bidang sedemikian rupa sehingga tidak ada dua sisi yang saling berpotongan. Graf pembagi-nol ini disebut sebagai graf planar. Karya ilmiah ini menjelaskan pembuktian teorema bahwa jika suatu graf pembagi-nol mempunyai graf yang isomorfik dengan graf lengkap dengan lima simpul atau graf bipartite lengkap dengan masing-masing himpunan simpul sebanyak tiga simpul, maka graf pembagi-nol ini bersifat tak-planar. Karya ilmiah ini juga membuktikan beberapa graf pembagi-nol merupakan graf planar atau tak-planar.
