Judul: Performa domba jantan lokal dengan perlakuan pakan yang berbeda selama dua bulan penggemukan
Abstrak: The aims of this study were to observe the performance of local male sheep, fed with experimental diets which were differentiated according the ratio of complete ration and grass (Brachiaria hurnidicola). The 12 local male sheep under one year old with average body weight of 15.87 1.00 kg (CV = 7.15%) were used in this study and allotted to the four experimental ration there were P1 (Complete feed 20% : Brachiaria humidicola 80%); P2 (Complete feed 80% : Brachiaria humidicola 20%); P3 (Complete feed 80% : Brachiaria humidicola 20% was given in the first month of the experiment then followed by Complete feed 20% : Brachiaria hurnidicola 80% for following month). The parameters measured were body weight gain, feed consumption, feed conversion ratio and Income Over Feed Cost. Randomized Complete Design were used in this experiment and the data were analyzed with analysis of variance (ANOVA). The result showed that the experimental treatment significantly (Pi0.05) affected daily feed consumption but the were no differences between treatments on body weight gain as well as feed conversion ratio. The highest profit was found in P2

Judul: Performance of Garut sheep on Different frequency of feeding
Abstrak: Penelitian ini bertujuan mengkaji frekuensi pakan yang berbeda terhadap pertambahan bobot badan domba jantan. Materi yang digunakan sebanyak 24 ekor domba jantan rataan bobot badan 21.8±1.48 kg dan rataan umur 1 tahun 5 bulan (I1). Metode penelitian yaitu menggunakan rancangan acak lengkap. Perlakuan yang diberikan adalah perlakuan F0 (5 kali hari-1) dengan konsentrat pemberian pakan pertama, perlakuan F1 (4 kali hari-1) dengan hijauan pakan pertama, dan perlakuan F2 (5 kali hari-1) dengan hijauan pakan pertama . Peubah yang diamati meliputi PBBH (Pertambahan Bobot Badan Harian), konsumsi BK (Bahan Kering), konversi pakan, dan efisiensi pakan. Data yang dianalisis ragam (ANOVA), dilanjutkan analisis Duncan. Hasil penelitian menunjukkan PBBH, konversi pakan, efisiensi pakan tidak berbeda nyata, sedangkan konsumsi BK berbeda nyata (P<0.05). Konsumsi BK pada F0 terendah dibandingkan F1 dan F2 serta F1 tertinggi. Simpulan penelitian ini adalah frekuensi pemberian pakan 5 kali hari-1 dengan hijauan sebagai pakan pertama dipagi hari menghasilkan performa yang lebih baik dibandingkan frekuensi 4 kali hari-1 serta frekuensi 5 kali hari-1 dengan pemberian konsentrat terlebih dahulu di pagi hari., This research is to examine different frequency feeding of weight gain on male sheep. Material used is 24 male sheep with average weight 21.8+-1.48 kg and average age 1 year 5 month (I1). Method used in this research is complete random design. Treatment which given is F0 (5 times in 1 day) with concentrate in a first give, treatment F1 (4 times in 1 day) with grasses in a first give, and treatment F2 (5 times in 1 day) with grasses in a first give. Variable which observed is ADG (Average Daily Gain), dry matter consumption, feed convertion, and feed efficiency. Data will analyzed with variate analysis, and then with Duncan analysis. Result of this research shown that ADG, feed convertion, and feed efficiency is not real different, while dry matter consumption is real different (P<0.05). Dry matter consumption on F0 treatment is a lowest than F1 and F2 treatment. Conclusion of this research is feeding 5 times in 1 day with grasses as a first feed on morning have better performance than 4 times in 1 day frequency and 5 times in 1 day frequency with concentrate in a first feed.

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
