Judul: Pengaruh pemberian infusa daun papaya [Carica papaya l.] pada mencit [Mus musculus albinus] yang diinfeksi Plasmodium berghei
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh pemberian infusa daun papaya (Carica papaya L.) pada mencit yang diinfeksi Plasmodium berghei. Pada penelitian ini digunakan sebanyak 30 ekor mencit putih (Mus musculus albinus) jantan dan betina dengan bobot rata-rata 25 gram. Penelitian ini menggunakan rancangan acak lengkap dengan tiga ulangan. Mencit dibagi dalam 5 kelompok perlakuan yaitu 1) kontrol positif (KP) yang diinfeksikan Plasmodium berghei tanpa pengobatan, 2) Sulfadoksin-Pirimetamin sebagai kontrol obat (KO), 3) kelompok PA1 (infusa daun Carica papaya L. dengan pengenceran 1x10²), 4) kelompok PA2 (infusa daun Carica papaya L. dengan pengenceran 1x10) dan 5) kelompok PA3 (infusa infusa daun Carica papaya L. dengan pengenceran 1x 10). Perhitungan parasit Plasmodium berghei melalui pengamatan ulas darah dengan mengunakan mikroskop pembesaran 1000x dan pengelolahan data menggunakan uji analisis sidik ragam (ANOVA)-SAS System dan Duncan Multiple Range Test. Pengamatan preparat ulas darah menunjukan bahwa rataan parasitemia mencit jantan selama sebelas hari pengamatan setelah infeksi menunjukkan bahwa kelompok perlakuan PA1 memiliki tingkat efektifitas paling tinggi dalam menekan pertumbuhan parasitemia (4,81%) sedangkan pada mencit betina tingkat efektifitas tertinggi terjadi pada kelompok perlakuaan PA3 (6,36%). Untuk jumlah kematian tertingi akibat infeksi Plasmodium berghei terjadi pada mencit betina…

Judul: Gambaran Leukosit Pada Mencit Yang Diinfeksi Plasmodium berghei Dan Diberi Infusa Daun Papaya (Carica papaya Linn.)
Abstrak: This research was conducted to determine the effect of Carica papaya Linn. leaf infusion to the percentage of differential leucocyte mice that was infected by Plasmodium berghei. This research used laboratory animals such as male and female mice (Mus musculus albinus) that had been infected by P. berghei. Design of this research was completely randomized design with three replication. About 30 mice with an average weight of 25 g were divided into 5 groups that consists of 1) KNO (normal control), 2) KN (negative control group) was infected P. berghei, 3) PA1 group (C. papaya L. leaf infusion with dilutions of 1 x 10-2), 4) PA2 (C. papaya L. leaf infusion with dilution 1 x 10-4) and 5) PA3 group (C. papaya L. leaf infusion with 1 x 10-6). The results showed that neutrophil percentage in male mice was tend to higher than female mice and KN group. Monocyte and eosinophil percentage in male and female mice was tend to lower than KN group. Lymphocyte percentage in male and female mice was tend to higher than KN group. Basophil percentage was not influence in all groups.

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.
