Judul: Konsumsi Minyak sawit Merah Meningkatkan Jumlah Sel Natural Killer dan Menurunkan Kadar Enzim Siklooksigenase 2 pada Limfosit Ibu Rumah Tangga di Kecamatan Dramaga Bogor.
Abstrak: Salah satu vitamin yang berperan penting dalam imunitas tubuh adalah vitamin A. Selain penting dalam mekanisme penglihatan, vitamin A juga dapat mencegah atau menurunkan resiko timbulnya berbagai penyakit degeneratif seperti kanker. Crude palm oil (CPO) yang berwarna merah sehingga sering disebut minyak sawit merah atau red palm oil tanpa melalui proses pemucatan merupakan sumber provitamin A dengan komponen utamanya α dan β-karoten yang memiliki aktivitas provitamin A (El-Hadad et al. 2011). β-karoten dikenal sebagai salah satu bahan alami pencegah kanker. ...dst

Judul: Konsumsi Minyak Sawit Mentah Meningkatkan Kadar Protein CD4 dan CD8 Limfosit Ibu Usia Produktif di Desa Dramaga dan Babakan,Kecamatan Dramaga Bogor
Abstrak: Vitamin A deficiency is one of the most serious health problem in Indonesia. Crude palm oil (CPO) contains high carotenoid, such as β–carotene, as a source of provitamin A. However, its use in Indonesia does not exist. Socialization and distribution can increase application of CPO. Palm oil has been reported to improve health. β–carotene as a provitamin A can modulate immune functions, enhance cell proliferation and play role as an anticancer. CD4 is a marker protein on T helper (Th) cells while CD8 is a marker protein on T cytotoxic (Tc) cells. Increasing level of CD4 and CD8 protein is expected to increase immune responses. 70 respondents were given CPO freely for 2 months with one bottle of CPO containing 140 ml per week and then lymphocyte from 16 healthy housewife respondents were analyzed by using Bradford and ELISA method. Respondents acceptance to CPO was observed. Lymphocyte analyzed showed that most of respondents had increasing level of CD4 protein from 0.095 to 0.117 and CD8 protein from 0.078 to 0.079. This research shows that CPO consumption can increase the level of CD4 and CD8 proteins and also can be used as an alternative source of provitamin A for tackling vitamin A deficiency problem. In addition, respondents can accept CPO as a new product very well because it can increase respondents’s health.

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.
