Judul: Analisis Sumberdaya Pangan di Kota Pagaralam Sumatera Selatan Tahun 2001-2010
Abstrak: This study aims to analyze the food resouces in Pagaralam, South of Sumatera in 2001-2010. The study design was retrospective with secondary data of Pagaralam in Figures. Secondary data includes Rencana Pembangunan Jangka Menengah Daerah (RPJMD) Pagaralam, Rencana Strategis (Renstra), food production, exports and imports, budgeting and number of population in Pagaralam City 2001-2010. Data processing covers production analysis, exports and imports, food availability and food suffiency by trend, line, ratio avaibility and ratio of imports analysis. Food availability policy and food avaibility budgeting were analyzed using content analysis. The results indicate increasing of production on some commodities but supply doesn’t fulfill the demand. Food avaibility is increased and energy suffiency has already reached the SPM (90%), but protein suffiency hasn’t reached the SPM. Desirable Dietary Pattern (DDP) score is still below 90. The food avaibility policy and budget are not support the Kebijakan Umum Ketahanan Pangan (KUKP) 2006-2010 and still focused on water resource management.

Judul: Analisis konsumsi dan kebutuhan untuk konsumsi pangan di provinsi Sumatera Barat, Jawa Tengah, dan Sulawesi Tenggara tahun 2005-2015
Abstrak: Saat ini Pemerintah Indonesia sedang berupaya keras melaksanakan kegiatan percepatan diversifikasi pangan, dengan harapan pada tahun 2015 konsumsi pangan masyarakat akan mendekati pola pangan harapan (PPH) dengan skor maksimal 100. Oleh karenanya penelitian tentang konsumsi dan permintaan pangan yang dapat memberikan gambaran pencapaian diversifikasi pangan sangat penting untuk dilakukan. Penelitian ini dilakukan dengan menggunakan data Susenas modul konsumsi tahun 2005. Tujuan penelitian adalah: (1) menganalisis tingkat kecukupan energi dan protein serta keragaman konsumsi pangan berdasarkan pendekatan PPH, (2) menganalisis respon permintaan pangan terkait perubahan harga pangan, dan perubahan pendapatan, (3) melakukan estimasi kebutuhan pangan wilayah pada tahun 2008-2015 berbasis data Susenas tahun 2005. Selain Susenas, data lain yang digunakan diantaranya adalah data proyeksi penduduk hasil sensus tahun 2000, dan data pertumbuhan ekonomi. Lokasi penelitian adalah Sumatera Barat, Jawa Tengah, dan Sulawesi Tenggara yang dibedakan antara wilayah perkotaan dan perdesaan.

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.
