Judul: Pengaruh Suplementasi Tepung Kunyit pada Herbal Mineral Blok (HMB) terhadap Profil Lemak Darah dan Performa Kambing Kacang
Abstrak: The purpose of this experiment was to study of supplementation of turmeric flour in Herb Mineral Block (HMB) on blood lipid profile and performance of Kacang goat. This experiment used a Completely Randomized Design, with three treatments and 10 replications. Treatments consisted of P1 (control), P2 (150 g turmeric flour in HMB), P3 (300 g turmeric flour in HMB). All animals fed with commercial feed diet during 45 days feeding trial. Variables observed were feed consumption, average daily gain, feed conversion, triglyceride, total plasma cholesterol, HDL and LDL-cholesterol. Result showed that supplementation of turmeric flour in HMB was not significance different in all parameters, compare to control treatment. Turmeric flour in Herb Mineral Block until 300 g is not effective as agent of decreasing cholesterol compound. Keywords : herb mineral block, blood lipid, kacang goat

Judul: Blood Profile and Mineral Status of Dorper sheep Fed Herbal Mineral Block (HMB)
Abstrak: Penelitian ini bertujuan menganalisis pengaruh suplementasi herbal mineral blok (HMB) mengandung tepung larva black soldier fly (BSF), tepung kunyit, dan mineral mikro terhadap profil darah dan status mineral darah. Penelitian menggunakan 10 ekor domba dorper jantan dengan rata-rata berat awal 17,49±1,65 kg yang ditempatkan pada kandang individu. Perlakuan yang digunakan yaitu P0 = pakan kontrol tanpa suplementasi HMB dan P1 = pakan kontrol dengan suplementasi HMB selama 56 hari. Parameter yang diukur adalah profil hematologi dan status mineral darah (Ca, P). Data dianalisis menggunakan Independent Sample T-Test. Hasil penelitian menunjukkan suplementasi HMB selama 56 hari tidak memberikan pengaruh yang nyata (P>0,05) terhadap profil hematologi, konsumsi nutrien dan status mineral darah (Ca dan P) pada domba dorper jantan. Pemberian HMB selama 56 hari belum mempengaruhi konsumsi nutrien, profil darah dan status mineral darah domba., This research was aimed to analyze the effect of herbal mineral block (HMB) containing black soldier fly (BSF) larvae meal, turmeric meal, and micro mineral supplementation on the hematology and was mineral status of lambs. This research used 10 lambs (initial weight of 17,49±1,65 kg) placed in an individual cage. The treatments used were P0 = ration control without HMB supplementation (control) and P1 = ration control with HMB supplementation for 56 days. The parameter measured were hematology and plasma mineral status of blood (Ca and P). Data were analyzed using independent sample T-test. Results of the study showed that HMB supplementation for 56 days had no significant effect on hematology profile, nutrient intake and plasma mineral status (Ca and P). It was concluded HMB supplementation for 56 days had no effect on nutrient intake, hematology, and blood mineral status of lambs.?

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.
