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: Konsumsi Minyak Sawit Mentah (MSMn) Dapat Diterima dan Memperbaiki Profil Lipid serta Menurunkan Kadar C-Reactive Protein (C-RP) Plasma Ibu Usia Produktif Di Kecamatan Dramaga Kabupaten Bogor.
Abstrak: Crude palm oil (CPO) contains carotenoids, including beta carotene around 400-1000 ppm as provitamin A and vitamin E (tocopherol and tocotrienol) around 559-1000 ppm. Fatty acid composition of red palm oil consists of 50% saturated fatty acids and 50% unsaturated fatty acids. Unsaturated fatty acids in red palm oil can up regulate LDL cholesterol receptors there by increasing catabolism of LDL cholesterol. Tocotrienols in palm oil can inhibit 3-hydroxy-3- methylglutaryl coenzyme A (HMG-CoA) reductase in cholesterol biosynthetic pathway. Beta carotene and vitamin E in red palm oil are powerful antioxidant against free radicals. C-reactive protein (C-RP) is a marker of inflammation, the antioxidants in red palm oil can reduce the incidence of inflammation. The purpose of this study was to determine the acceptance of CPO as cooking oil and the effect of its consumption on lipid profile and C-reactive protein. Subjects total of 151 families, including 508 respondents were given 140 ml CPO in plastic bottle weekly for 2 months freely. The distribution was accompanied with socialization of oil benefit and utilization with five types of questionnaires. For plasma analysis, blood from 33 mothers of childbearing age were withdrawn before and after oil distribution and analyzed for C-reactive protein and lipid profile. The oil was accepted by the respondent and used as cooking oil. The results showed that consumption of red palm oil reduce absorbance levels of CRP from 0,111 to 0,103, total cholesterol from 168,3 mg/dL to 158,0 mg/dL, LDL cholesterol from 98,7 mg/dL to 81,1 mg/dL, ratio total cholesterol:HDL from 4,3 to 3,5 and increase HDL cholesterol from 41,5 mg/dL to 45,6 mg/dL was significantly (p <0.05), but not significantly lower triglyceride levels

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.
