Judul: Pengaruh Pendidikan Gizi melalui Diskusi dan Permainan Edukatif Kubus Bergambar terhadap Pengetahuan Gizi Seimbang Siswa Sekolah Dasar Kabupaten Bogor
Abstrak: The purpose of this study was to determine the influence of nutritional education with discussion and educative game cube on nutritional knowledge of elementary school student in a Bogor district. This research used a quasy experimental study with a pre-test-post-test. The subject of this study involved 93 students at 5th grade, which are the student of Islamic Integrated of Elementary School Tarbiyatunnisaa and KAIFA (first treatment group) and Islamic Integrated of Elementary School KAIFA (second treatment group). There was no relationship between parent’s education level and birth order level with nutritional knowledge (p>0.05). Nutritional education with the game cubes positif effect on the level of nutrition knowledge elementary students about nutrition balanced. T test analysis showed that significant difference between nutritional knowledge at the first and second group (p<0.05). 91.2% of the sample expressed a very attractive picture cube media used in nutritional counseling.

Judul: Pendidikan Gizi Menggunakan Media Permainan Kwartet terhadap Pengetahuan dan Praktik Gizi Seimbang Siswa Sekolah Dasar
Abstrak: Intervensi gizi menggunakan media kepada siswa sekolah dasar dapat lebih mudah dan lebih cepat diterima dengan perasaan senang serta dapat diterapkan dengan baik. Penelitian ini bertujuan untuk mengetahui pengaruh media permainan kwartet terhadap pengetahuan dan praktik gizi seimbang. Penelitian ini menggunakan desain quasi experimental study dengan one group pre test-post test yang dilaksanakan pada bulan Maret-Mei 2019 di SDN 1 Kayumanis, Kota Bogor. Subjek merupakan siswa kelas 5 dengan jumlah 75 orang. Strategi intervensi yaitu wawancara FFQ sebelum intervensi, pre test, intervensi, post test 1, post test 2 satu bulan setelah intervensi, dan wawancara FFQ setelah intervensi. Skor pengetahuan dan praktik gizi meningkat pada post test 1 dan post test 2, tetapi masih berada dalam kategori yang sama yaitu sedang. Perbedaan pengetahuan gizi sebelum dan setelah intervensi sangat signifikan (p=0.000). Perbedaan praktik gizi sebelum dan setelah intervensi menunjukkan hasil yang signifikan (p=0.036). Hubungan pengetahuan dan praktik gizi seimbang sebelum intervensi menunjukkan hasil yang signifikan (p=0.004), sedangkan setelah intervensi tidak signifikan (p=0.098). Hubungan pengetahuan dan praktik gizi dengan pola konsumsi sebelum dan setelah intervensi tidak signifikan (p>0.05). Media permainan kwartet dapat meningkatkan pengetahuan dan praktik gizi subjek, tetapi belum mampu untuk meningkatkan konsumsi subjek pada setiap golongan makanan.

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.
