Judul: The Effect of Vitamin E (dl-a-Tocopherol Acetate) Suplementation on Performances and Some Characteristic of Rabbit Carcasses
Abstrak: Vitamin merupakan salah satu zat makanan yang mempunyai peranan penting dalam fungsi sel tubuh sehingga penting untuk diperhatikan. Salah satu vitamin yang esensial bagi temak adalah vitamin E, karena tubuh temak tidak dapat mensintesa, sehingga perlu ditambahkan dalam ransum. Untuk mengetahui dan mempelajari (baik langsung maupun tidak langsung) pengaruh penambahan vitamin E (dl-a-Tocopherol Acetate) dalam ransum, maka dilakukan pengamatan terhadap 30 ekor kelinci New Zealand White persilangan lepas sapih dengan melihat penampilan dan beberapa sifat karkasnya., The effect of vitamin E (dl-a-Tocopherol Acetate) supplementation in diets on performances and some characteristic of rabbit carcasses was studied in thirty post weaning female rabbits. The design of the experiment was completely randomized with five treatments and six replications. Five treatments were EO= basal ration (without suplementation dl-a-Tocopherol Acetate), E50= EO + 50 mg dl-a -Tocopherol Acetatelkg diet, E100 = EO + 100 mg dl-a - Tocopherol Acetatelkg diet, E150 = EO + 150 mg dl-a -Tocopherol Acetatelkg diet, and E200 = EO +200 mg dl-a -Tocopherol Acetatelkg dies. All meat from the right side carcasses were separated to determine dry matter (water content), fat (ether exstract), protein, saturated fatty acids and unsaturated fatty acid content.

Judul: Vitamin E Supplementation in Diets on The Percentage of Carcasses and Non Carcasses, and Meat Bone Ratio in IPB-D3
Abstrak: Tujuan penelitian ini adalah untuk mengevaluasi suplementasi vitamin E dalam ransum terhadap persentase karkas, non karkas, serta rasio daging tulang ayam IPB-D3 dalam ransum yang berbeda. Penelitian ini menggunakan 160 ekor ayam IPB-D3 yang diberi ransum perlakuan dari umur 5 sampai 12 minggu. Penelitian ini menggunakan rancangan acak lengkap (RAL) pola faktorial dengan dua faktor yaitu jenis ransum (SNI dan SNI+10%) dan suplementasi vitamin E (0 ppm dan 200 ppm). Perlakuan ransum yang diberikan adalah sebanyak 4, yaitu (P1) ransum SNI, (P2) ransum SNI+10%, (P3) ransum SNI+vitamin E 200 ppm, dan (P4) ransum SNI+10%+vitamin E 200ppm. Hasil penelitian menunjukkan bahwa jenis ransum SNI+10% meningkatkan persentase bobot karkas, tetapi menurunkan panjang relatif bobot duodenum, persentase jejunum, panjang relatif jejunum, panjang relatif ileum, dan persentase sekum. Kesimpulan penelitian ini adalah jenis ransum dengan kandungan 10% lebih besar dari SNI ayam kampung mampu meningkatkan bobot karkas ayam IPB-D3., The purpose of this study was to evaluate vitamin E supplementation in the diet to the percentage of carcass, non carcass, and meat bone ratio of IPB-D3 chicken in different diets. This study used 160 IPB-D3 chickens that were given treatment diets from 5 to 12 weeks of age. This study used a factorial RAL pattern with two factors, namely the type of diet (SNI and SNI + 10%) and vitamin E supplementation (0 ppm and 200 ppm). The diets treatments given were 4, namely (P1) diet SNI, (P2) diet SNI+10%, (P3) diet SNI+vitamin E 200 ppm, and (P4) diet SNI+10%+vitamin E 200ppm. The results of the analysis showed that the type of diet SNI+10% increased the percentage of carcass weight, but decreased the relative length of the duodenum, the percentage of the jejunum, the relative length of the jejunum, the relative length of the ileum, and the percentage of the cecum. The type of SNI diet for native chickens with nutrients above 10% was able to increase the carcass weight of IPB-D3 chickens. The type of SNI diets for native chickens with nutrients above 10% was able to increase the carcass weight of IPB-D3 chickens.

Judul: Kekonsistenan Hamiltonian pada Gerak Gelombang Interfacial
Abstrak: The interfacial wave is an internal wave that occurs at boundary of two layers fluid. It appears because there is difference of mass density between the two layers. The objective of this thesis is to formulate the motion of internal wave with flat base and flat as well as free upper bound surface. The motion equation obtained is a Hamiltonian system. The Hamiltonian in this system is expressed by variable of wave deviation and horizontal component of potential velocity. Under assumption that interfacial wave moves only in one direction, it can be shown that the Hamiltonian depends on the solution of the wave motion equation. The coefficients of the equation depend on the physical characteristics of the two layers of fluid, i.e. thickness and mass density. The numerical results show that Hamiltonian in the system is constant. It is consistent with Hamiltonian characteristic, which does not depend on time.
