Judul: Performance Of Mice (Mus musculus) Given Additional Papaya Fruit In Feed
Abstrak: Mencit putih (Mus musculus) merupakan hewan mamalia yang memiliki banyak manfaat, baik sebagai pakan ular dan hewan reptil lain, juga dimanfaatkan sebagai hewan percobaan/hewan laboratorium. Pepaya california mempunyai kandungan gizi yang tinggi seperti vitamin A dan C, pepaya juga memiliki kadar air yang cukup tinggi sebesar 86,7 g dan serat sebesar 0,7 g pada setiap 100 g daging buah pepaya. Penelitian ini bertujuan untuk menganalisis performa mencit putih yang diberi penambahan buah pepaya dalam pakan dengan taraf yang berbeda. Penelitian ini menggunakan 80 ekor mencit putih. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dengan empat perlakuan yaitu pemberian pakan tambahan buah pepaya P1; 0%; P2; 5%; P3; 10%; P4; 15%, dan empat ulangan. Data yang diperoleh dianalisis menggunakan ANOVA, hasil yang berbeda diuji lanjut dengan uji Duncan. Hasil penelitian menunjukkan bahwa pada jumlah konsumsi air minum mencit putih berbeda nyata (P<0,05), sementara pertambahan bobot badan dan mortalitas tidak berbeda nyata (P>0,05). Perlakuan tanpa penambahan buah papaya, menunjukkan hasil yang lebih baik dibanding dengan perlakuan lainnya., Mice (Mus musculus) is mammal that has many benefits as feed for other reptile, and used as experimental animals. Papaya California has a high nutritional content such as vitamins A and C, contain high water content of 86.7 g and fiber of 0.7 g in every 100 g papaya flesh. This study aimed to analyze the performance of Mice given additional papaya fruit in mouse feed at different levels. This study used 80 white mouse, and applied a complete randomized design (RAL) with four treatments including the additional level of papaya fruit i.e.: T1; 0%; T2; 5%; T3; 10%; T4; 15% with four replication. Data was analyzed using ANOVA. The difference results were tested using Duncan test. The results showed that the amount of drinking water consumption was significantly different (P<0.05) between treatments, which was higher in while the body weight gain and mortality rate was not significantly different (P>0.05) between treatmens. Mouse given feed without papaya fruit treatment showed better results than other treatments.

Judul: Performance of White Mouse (Mus musculus) on Use of Different Litters
Abstrak: Manajemen pemeliharaan pada aspek perkandangan merupakan salah satu hal yang penting, karena dengan kondisi kandang yang baik dapat memberikan kenyamanan terhadap mencit sehingga produktivitas dan performa menjadi meningkat. Salah satu alternatif pada aspek perkandangan yang dapat diupayakan untuk meningkatkan produktivitas dan performa mencit yang baik yaitu pemakaian jenis alas kandang. Penelitian ini bertujuan mengetahui pengaruh perbedaan penggunaan alas media yang berbeda terhadap pertambahan bobot badan, jumlah konsumsi air, jumlah anak serta mortalitas pada mencit putih. Penelitian ini menggunakan rancangan acak lengkap dengan tiga perlakuan dan empat ulangan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata terhadap pertambahan bobot badan, jumlah konsumsi air, jumlah anak serta mortalitas. Pertambahan bobot badan mencit putih tertinggi pada perlakuan alas sekam (P1) sebesar 20,54 ± 3,83 g, jumlah konsumsi air mencit putih tertinggi pada perlakuan alas sekam (P1) sebesar 26,85 ± 1,15 ml, jumlah anak tertinggi mencit putih pada perlakuan alas zeolit (P2) sebesar 6,50 ± 2,34 ekor, dan mortalitas tertinggi pada perlakuan alas kertas (P3) sebesar 0,25 ± 0,20 ekor., Maintenance management in the housing aspect is one of the important things, because good cage conditions can provide comfort for mice so that productivity and performance will increase. One alternative in the cage aspect that can be sought to increase the productivity and good performance of mice is the use of a type of cage mat. This study aims to determine the effect of differences in the use of different litters on body weight gain, amount of water consumption, number of children and mortality in mice. This study used a completely randomized design with three treatments and four replications. The results showed that the treatment had no significant effect on body weight gain, total water consumption, number of children and mortality. The highest weight gain of white mouse was in the husk base treatment (P1) of 20.54 ± 3.83 g, the highest amount of water consumption of white mouse was in the husk base treatment (P1) of 26.85 ± 1.15 ml, the highest number of children was mice in the treatment zeolite base (P2) was 6.50 ± 2.34, and the highest mortality was in the paper mat treatment (P3) was 0.25 ± 0.20.

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.
