Judul: Performa Produksi Ayam Arab Petelur yang Diberi Jamu Ternak Melalui Air Minum
Abstrak: This research was conducted on June until August 2011 in the Faculty of Animal Science, Bogor Agricultural University to evaluate the laying performance of Arab hens fed herbs mixture trough drinking water. Herbs mixture was composed from lesser galangal, garlic, ginger, galangal, turmeric, ginger, green betel leaves, cinnamon, molasses and effective microorganisms (EM4). All herb materials were incubated for 5 days. Readily use herbs mixture was given to the hens through dringking water for three consecutive days in a week during 6 weeks experiment. A total of 48 of Arab hens age 19 weeks were kept and subjected to 3 different treatments of herbal mixture addition in drinking water. The treatments were no herbal mixture (P0), 5 ml/day (P1) and 10 ml/day (P2). This research was designed completely randomized (CRD). Data were subjected to analysis of variance (ANOVA) and the differences between treatments were tested by Duncan’s multiple range test. Variables measured were feed consumption, feed conversion, hen day production and mortality. The feed consumption revealed no significant differences among treatments. However, the feed conversion increased and hen day production decreased significantly at the higher level addition of herbal mixture. Herbs mixture showed no harmful effect on hens health.

Judul: Penambahan Jamu Ternak dalam Air Minum terhadap Uji Daya Hambat Bakteri Salmonella dan Escerichia coli serta Performa Ayam Arab Petelur
Abstrak: Jamu ternak adalah ramuan tradisional yang dibuat dari bahan alami terutama tumbuhan dan merupakan warisan budaya bangsa yang telah digunakan turun temurun. Jamu ternak yang dibuat berasal dari kencur, bawang putih, jahe, lengkuas, kunyit, temulawak, daun sirih hijau, dan kayu manis yang masih segar, ditambah molasses dan EM4. Penelitian ini bertempat di Peternakan Ayam Arab Trias Farm Desa Cempelang-Cibatok Leuwiliang, Kabupaten Bogor. Penelitian ini menggunakan jamu tradisional yang dicampurkan dalam air minum ternak. Jamu tradisional ini dibuat dari kencur 750 g, bawang putih 750 g, jahe 375 g, lengkuas 375 g, kunyit 375 g, temulawak 375 g, daun sirih hijau 187,5 g, dan kayu manis 187,5 g yang masih segar, dan penambahan molases dan EM4 (Saenab et al., 2002). Ternak yang digunakan dalam penelitian ini adalah ayam arab periode bertelur berumur satu tahun sebanyak 1040 ekor yang dialokasikan ke dalam 4 perlakuan dengan dosis setiap perlakuan 10 ml/ekor/hari, 20 ml/ekor/hari dan 30 ml/ekor/hari dan perlakuan kontrol. Semua bahan diinkubasikan selama 5 hari dan jamu ini diberikan selama tiga hari berturut-turut selama seminggu. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan 4 perlakuan dan 2 ulangan. Data diolah dan dianalisis menggunakan ANOVA (Analysis of Variance) dan jika memberikan hasil yang berbeda nyata maka dilanjutkan dengan uji jarak Duncan. Peubah yang diukur adalah uji fitokimia & daya hambat terhadap bakteri Salmonella dan Escerichia coli, pengaruh jamu ternak terhadap performa ayam Arab (konsumsi ransum, konversi ransum, produksi telur, dan mortalitas).

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
