Judul: Perilaku guru sekolah dasar terkait gizi dan keamanan pangan
Abstrak: Guru sangat berperan penting dalam pengenalan pendidikan gizi di sekolah sebagai dasar bagi pembinaan kebiasaan makan yang sehat dan aman bagi murid. Tingkat pengetahuan gizi dan keamanan pangan guru SD akan berpengaruh pada tingkat pengetahuan anak didiknya. Sikap dan praktek guru juga harus dapat mencontohkan perlaku makan yang bergizi dan aman bagi murid. Mengingat pentingnya arti pendidikan mengenai gizi dan keamanan pangan bagi anak usia sekolah dasar guna pembentukan perilaku makan yang baik dan sehat, maka diperlukan tenaga pendidik yaitu guru yang memiliki perilaku yang baik terkait gizi dan keamanan pangan. Tujuan umum penelitian ini adalah untuk mengkaji perilaku guru sekolah dasar (SD) terkait gizi dan keamanan pangan yang mencakup aspek pengetahuan, sikap dan praktek berdasarkan wilayah (kota dan kabupaten) dan akreditasi sekolah. Adapun tujuan khusus dari penelitian ini adalah (1) Mengidentifikasi karakteristik individu (umur, jenis kelamin, pendidikan terakhir, dan lama bekerja sebagai guru) dan sosial ekonomi keluarga (besar keluarga dan tingkat pendapatan keluarga) guru SD, (2) Mengidentifikasi perilaku (pengetahuan, sikap dan praktek) guru SD terkait gizi dan keamanan pangan, dan (3) Menganalisis hubungan karakteristik individu dan sosial ekonomi keluarga guru SD dengan perilaku (pengetahuan, sikap dan praktek) guru SD terkait gizi dan keamanan pangan. Desain penelitian ini menggunakan cross sectional study. Sekolah yang dijadikan lokasi penelitian adalah SDN Lawanggintung 01 (Akreditasi A) dan SDN Cimanggu Kecil (Akreditasi B) di wilayah kota serta SDN Pajeleran 01 (Akreditasi A) dan SDN Kotabatu 01 (Akreditasi B) di wilayah kabupaten. Guru dalam penelitian ini adalah guru SD yang masih aktif mengajar dan bersedia mengisi kuesioner. Berdasarkan kriteria tersebut didapat 19 orang guru di kota dengan akreditasi A, 15 orang guru di kota dengan akreditasi B, 23 orang guru di kabupaten dengan akreditasi A dan 11 orang guru di kabupaten dengan akreditasi B. Penelitian ini merupakan bagian dari penelitian "Pengembangan Model Pendidikan Makanan Jajanan Sehat Berbasis Sekolah untuk Tingkat Sekolah Dasar yang dilakukan oleh SEAFAST Center-Lembaga Penelitian dan Pengabdian Kepada Masyarakat (LPPM) Institut Pertanian Bogor, penelitian dilakukan mulai bulan Mei hingga Juli 2009. ...

Judul: Persepsi guru sekolah dasar pada media pendidikan gizi terkait perilaku gizi dan keamanan pangan
Abstrak: Teacher had an important role toward the introduction of nutrition and food safety at school as a basic for student eating custom and safety development. Teacher standarization of nutrition and food safety knowledge would have an influence to the student knowledge. The teachers might be the sample for their student in eating nutrition habit and food safety. It remind us how important the meaning of nutrition education and food safety for students elementary school in order to formed good eating and healthy, so we need a teacher who good behavior related to the nutrition and food safety. The general purpose of this study was to analyze the influence of knowledge, attitude, practices related to nutrition and food safety toward the teachers perception on the nutrition education media according to the region and school accreditation, meanwhile the specific purpose of this study were (1) to analyze the social economic teacher’s characteristic, (2) to analyze the teacher’s knowledge, attitude, practices related to nutrition and food safety, (3) to analyze the teacher’s perception on media, such as moduls, leaflets, posters, flip chart and nutrition education booklets, and (4) to analyze the influence of nutrition behavior and food safety toward the teacher’s perception on nutrition education media. The design of the study was cross sectional study. The location of the study was at Lawanggintung 01 Elementary School (A accreditation) and Cimangu Kecil Elementary school (B accreditation) in Bogor urban, Pajeleran 01 Elementary School (A accreditation) and Kotabatu Elementary School (B accreditation) in Bogor rural. The teacher’s in this study were active teacher’s and had willing to filled the questionnaire and there were 68 teachers. This study was a part of the study “Developing Model of Healthy Street Food on Elementary School” by SEAFAST center–LPPM Bogor Agricultural Institute, the study started from July 2009 to June 2010. The primary data include the social economic characteristic (gender, age, level of education, length of worked as teacher, family member, and level of family income), behavior (knowledge, attitude, practice) related to nutrition and food safety, teachers perception to the nutrition education media. The primary data did by filling the questionnaire. Secondary data include the general school condition which got from questionnaire. Data processing and analyzing were processed by computer programme microsoft excell and Statistical Program for Social Science (SPSS) version 16.0 for windows. Generally female techers (75%) were more than male (25%). The age of the teaches at middle aged group (61.8%) and the average of the teachers age both male of female were 42.3 years old. The level of elementary teacher school were S1 (47.1%) and diploma (47.1%), the length of worked as teacher between 21-30 years (42.6%), whereas family member 77.9%, teacher family which was include small family category (≤ 4 person), 55.9% teachers had income in the range Rp500 000 – Rp1 000 000 capita/month. The result of the analysis showed that 50% teacher elementary school had medium knowledge about nutrition and food safety, but when it viewed from school accreditation it told that the school which had A accreditation (medium category 54.76%) was better than school

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.
