Judul: Telaah interaksi sosial masyarakat sasaran terhadap kesinambungan program intervensi diversifikasi konsumsi pangan dan gizi
Abstrak: Tujuan penelitian ini adalah: (1) Mempelajari pengadaan pangan melalui usahatani, luar usahatani, dan tingkat pendapatan; (2) Mempelajari komunikasi masyarakat sasaran serta dukungan dan motivasi tokoh formal dan non-formal terhadap kesinambungan program intervensi diversifikasi konsumsi pangan dan gizi; (3) Mempelajari interaksi sosial kelompok Mitra dan Non-mitra terhadap program intervensi diversifikasi konsumsi pangan dan gizi; (4) Mempelajari efek sebaran dari kelompok Mitra kepada Non-mitra dan efek jendela dari Non-mitra terhadap program intervensi diversifikasi konsumsi pangan dan gizi; (5) Mempelajari pengetahuan (knowledge), sikap (attitude) dan tindakan konsumsi (practice) kelompok Mitra dan Non-mitra terhadap kesinambungan program intervensi diversifikasi konsumsi pangan dan gizi; (6) Mempelajari perbedaan pengetahuan, sikap dan tindakan konsumsi pangan dan gizi antara kelompok Mitra dan Non-mitra; (7) Mempelajari adopsi program intervensi diversifikasi konsumsi pangan dan gizi kelompok Mitra. Penelitian ini dilaksanakan di Kabupaten Bogor, Propinsi Jawa Barat. Pemilihan lokasi penelitian didasari pada penelitian hibah bersaing yang dilakukan oleh Jurusan Gizi Masyarakat dan Sumberdaya Keluarga-Fakultas Pertanian IPB tahun 1993-1996, yaitu Desa Sukajadi Kecamatan Ciomas bertipologi pertanian campuran dan Desa Kiarasari Kecamatan Cigudeg bertipologi pertanian dominan padi (Kusharto et al, 1994). Pelaksanaan penelitian sejak April sampai dengan Desember 1996. Pengambilan contoh dilakukan secara "stratified dan purposive random sampling", yaitu: (1) Penentuan secara stratified dilakukan terhadap kelompok yang menerima paket program intervensi pangan dan gizi (Mitra 1 dan Mitra 2), dan kelompok yang belum menerima paket program inter- vensi diversifikasi konsumsi pangan dan gizi; (2) Penentuan informan kunci dilakukan secara purposive; (3) Penentuan contoh: a) Secara purposive terhadap seluruh anggota kelompok Mitra, yaitu Kelompok Mitra 1 sebanyak 4 rumahtangga, Mitra 2 sebanyak 38 rumahtangga, b) secara random terhadap Non-mitra sebanyak 33 rumahtangga. Total responden sebanyak 115 rumahtangga.

Abstrak: DIAH IMAS SRIMARYANI. Food Consumption Pattern and Nutritional Status among Household of Community Empowerment Program Participants in Bogor. Supervised by DADANG SUKANDAR and YAYUK FARIDA BALIWATI The objective of this research was to analyze food consumption pattern and nutritional status of households who were being the participant of community empowerment program. This research was about factors that influenced food consumption pattern and nutritional status of households. The factors which influenced food consumption pattern and nutritional status of households were analyzed by regression test. The regression test showed that income influenced sufficiency level of energy (p<0,05), education influenced the sufficiency level of protein (p<0,05), age influenced the sufficiency level of calcium (p<0,05), and age influenced sufficiency level of vitamin A (p<0,05). Factors which was significantly influenced the nutritional status was size of households. Based on regression test, the value of R square (R2) was 0,116. The impact of households size to the Body Mass Index (BMI) was 11,6% (R2 x 100%). Keywords : food consumption pattern, nutritional status, household of community empowerment program

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.
