Judul: Pemberian Tepung Daun Saga Rambat dan Kemuning terhadap Kecacingan pada Kambing Peranakan Etawah Laktasi
Abstrak: Penyakit kecacingan merupakan penyakit yang dapat mengganggu kesehatan ternak. Penelitian dilakukan untuk menguji pengaruh pemberian tepung daun saga rambat (Abrus precatorius) dan kemuning (Murraya paniculata) terhadap penyakit kecacingan pada kambing Peranakan Etawah laktasi. Dua belas ekor kambing PE dengan rataan bobot badan 49.4±8.5 kg, kali beranak 2-4 kali dan rataan produksi susu 940±310 mL ekor-1hari-1, dikelompokkan secara acak ke dalam 3 kelompok. Penelitian terdiri atas 4 perlakuan, P0 (kontrol), P1 (tepung daun saga 4.3%), P2 (tepung daun kemuning 0.7%), dan P3 (kombinasi tepung daun saga dan kemuning). Setiap perlakuan terdiri dari 3 ekor kambing. Data dianalisis menggunakan analisis sidik ragam (ANOVA). Hasil pengamatan menunjukkan perlakuan tidak memberikan pengaruh terhadap konsumsi dan profil darah, namun ada indikasi penurunan jumlah telur cacing setelah dua minggu perlakuan. Kesimpulan penelitian ini adalah pemberian tepung daun saga 4.3%, daun kemuning 0.7%, maupun kombinasi keduanya belum mampu membasmi penyakit kecacingan pada kambing PE laktasi, namun ada indikasi perlakuan tepung daun kemuning lebih potensial dibandingkan perlakuan lainnya dalam menurunkan jumlah telur cacing.

Judul: Manfaat Tepung Daun Kemuning (Muraya paniculata [L.] Jack) dalam Menekan lnfestasi Cacing Saluran Pencernaan Kambing PE
Abstrak: Nematodiasis is one of the obstacles in achieving optimum milk productivity. Kemuning leaves (Muraya panicu/ata [L.] Jack) is a herb with a active compound has anthelmintik activity. The aim of this research was to study the influence of kemuning leaves as anti parasites in the digestive tract. The research consists of the RO (control), R I (concentrates containing of 10% Date Fruit Waste (DFW) and kemuning leaves meal (1 %), R2 concentrate contains of 20% Date Fruit Waste (DFW) and kemuning leaves meal I %. Nine lactating Etawah crossbred goats of 56.5±7.3 Kg body weight, number of calving of 1-4 times and average milk production 849±168 rnL day" , randomly grouped into 3 groups and each treatment 3 replicates. Data analyzed with analysis of variance (ANOV A). The result showed that the treatment were not affected on performance (feed intake, digestibility, ' and AD G), EPG and physiological response (heart rate, rectal temperature and breath frequency). Kemuning leaves have potential as anthelmintic and works better in suppressing the development of eggs of Trichuris sp. parasites than Strongylid sp.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
