Judul: Studi hematologis potensi metabolik jambu biji merah (Psidium guajava L.) pada penderita demam berdarah Dengue
Abstrak: Sari jambu biji merah telah diberikan kepada 17 pasien laki-laki dan 10 orang pasien perempuan yang dibagi menjadi pasien kontrol dan perlakuan. Pasien kontrol adalah pasien yang tidak diberi sari buah jambu biji merah dan perlakuan adalah pasien yang diberi sari buah jambu biji merah dengan dosis 200 mL tiga kali sehari. Kedua kelompok pasien ini tetap diberi terapi rumah sakit. Pasien laki-laki dibagi menjadi 8 kontrol dan 9 perlakuan, 10 orang pasien perempuan dibagi menjadi 5 kontrol dan 5 perlakuan dengan umur antara 15-30 tahun dan didiagnosis terinfeksi DBD menurut metoda World Health Organization (WHO). Analisis darah setiap 12 jam sekali dengan menggunakan alat hitung darah flow cytometri. Hasil yang diperoleh, pemberian sari jambu biji merah kepada pasien DBD tidak berpengaruh nyata (p>0.05) terhadap nilai trombosit, hematokrit, dan hemoglobin, tetapi pemberian sari jambu biji merah mempengaruhi presentase nilai trombosit dan hematokrit. Pemberian sari jambu biji merah terhada p pasien laki-laki dan perempuan mampu memperbaiki penurunan trombosit rata -rata sebesar 31.28% dan 23.6% dibandingkan pasien kontrol. Pemberian sari jambu biji merah kepada pasien laki-laki dan perempuan mampu menurunkan hematokrit rata-rata sebesar 1.51% dan untuk pasien perempuan rata -rata sebesar 10.94% dibandingkan pasien kontrol.

Judul: Hematologic Study of Metabolic Potention Red Guava (Psidium guajava L.) on Dengue Hemorhagic Fever (DHF) Patient.
Abstrak: Red guava juice had been given to 17 male and 10 female patients who were divided into treatment and control patients. Control patients were the patients who were not given red guava juice and treatment patients were the patients who were given red guava juice 200mL three times a day. Both were given therapy by the hospital. Male patients were divided into 8 control and 9 treatment patients, 10 women patients were divided into 5 control and 5 treatment patients whose age ranged between 15-30 years old and were diagnosed to be infected by DHF according to the World Health Organization (WHO) method. Blood analysis was done once every 12 hours by using flow cytometri. The result showed that the red guava juice giving to the DHF patients was not significantly different (p>0.05) to the blood values, but it affected to the percentage value of trombocyte and hematocryte. The red guava juice giving to the male and female patient was able to improve trombocyte decreasing to 31.28% and 23.6% respectively. It was also able to reduce the percentage of hematocryte until 1.51% for male and 10.94% for female.

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.
