Judul: Pengaruh Pendidikan Gizi terhadap Kadar Hemoglobin Mahasiswa Putri TPB IPB yang Diberi Suplementasi Multivitamin Mineral
Abstrak: Anaemia is still prevalence in Indonesia especially in adolescent girls because deficiency of iron and folic acid. The purpose of this study was to analyze the effect of multivitamin minerals supplementation and nutrition education on haemoglobin. The study was conducted on First Common Year Studentsof Bogor Agricultural University. Design of the study was Quasy Experimental with pretest post test group. The number of subjects was 27 and allocated into two groups. First group received multivitamin minerals supplementation without nutrition education (S group); second group received multivitamin and minerals supplementation with nutrition education (SPG group). The method of nutition education was speech and allocated into four session with duration 30-45 minutes for each meeting. The result of the study showed that nutrition education affected nutritional knowledge but could not improve nutritional attitudes and nutritional practice. There was no significant correlation between nutrition knowledge, attitude, and practice. Multivitamin minerals supplementation could not improve haemoglobin, but could increased haemoglobin of anaemia subject although the increase was not significant (p>0.05).

Judul: Efek suplementasi multivitamin mineral terhadap kadar hemoglobin dan hematokrit mahasiswi TPB IPB
Abstrak: Anemia merupakan salah satu masalah gizi serius di Indonesia. Prevalensi anemia pada kelompok remaja putri, khususnya siswi masih cukup tinggi (Anggareini 2004; Briawan 2008). Program perbaikan anemia sering dilakukan dalam berbagai penelitian, salah satunya melalui mineral multivitamin suplementasi. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh multivitamin suplementasi mineral terhadap konsentrasi hemoglobin dan hematokrit kota bogor Mahasiswa perempuan Tahun Biasa Pertama Universitas Pertanian. Desain penelitian ini adalah eksperimen semu, buta ganda. Jumlah sampel sebanyak 28 siswi yang selanjutnya dibagi menjadi 2 kelompok. Kelompok intervensi terdiri dari 15 sampel, mendapat suplemen sirup 15 ml per hari selama 8 minggu. Kelompok kontrol terdiri dari 13 sampel yang menerima sirup plasebo. Data dikumpulkan dengan wawancara sampel menggunakan kuesioner, pemeriksaan fisik, dan pemeriksaan biokimia darah. Hasil uji statistik (paired sample t test) menunjukkan tidak terdapat peningkatan kadar hemoglobin dan yang signifikan konsentrasi hematokrit masing-masing pada kelompok intervensi dan kontrol (p>0,05). Namun, pada sebagian sampel anemia, kadarnya meningkat hemoglobin dan hematokrit pada kelompok intervensi cenderung lebih besar dibandingkan kelompok intervensi kelompok kontrol.

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.
