Judul: Analisis realisasi kebutuhan pangan berdasarkan sumberdaya pangan di Kabupaten Muara Enim tahun 2004-2011
Abstrak: Penelitian ini bertujuan untuk menganalisis realisasi kebutuhan pangan tersebut meliputi ketersediaan pangan dan kebutuhan konsumsi berdasarkan sumber pangan di Kabupaten Muara Enim tahun 2004-2011. Kajian ini merupakan bagian dari “Ketahanan Pangan Kajian Rencana Induk Kabupaten Muara Enim”, yang diselenggarakan oleh Fakultas Ekologi Manusia, Institut Pertanian Bogor dan Badan Perencanaan Pembangunan Daerah (BAPPEDA) Kabupaten Muara Enim. Penelitian ini dirancang secara retrospektif oleh data sekunder produksi pangan, impor, ekspor, ketersediaan pangan dan konsumsi dari Kantor Ketahanan Pangan (KKP) Kabupaten Muara Enim. Pengolahan data dimulai dengan menghitung ketersediaan dan konsumsi pangan target dengan memproyeksikan Pola Pangan yang Diinginkan (DDP) dari tahun dasar 2004 terhadap nilai DPP yang diharapkan dalam Standar Pelayanan Minimal (SPM) ketahanan pangan adalah 90 pada tahun 2015. Target tersebut dibandingkan dengan ketersediaan pangan dan realisasi konsumsi selama tahun 2004-2011. Analisis dibagi menjadi dua bagian, yang pertama menurut kecukupan energi (kuantitatif) dan yang kedua menurut Skor DDP (kualitatif). Sumber pangan di Kabupaten Muara Enim sebagian besar dihasilkan dari sektor produksi. Komoditas beras merupakan komoditas tertinggi di tahun ini sektor produksi dan ekspor dibandingkan produk khusus lainnya seperti gandum, jagung, singkong, gula pasir, kedelai, dan daging sapi. Terwujudnya ketersediaan pangan secara kuantitatif telah melampaui target setiap tahunnya, kecuali pada tahun 2008 dan 2010. Realisasi ketersediaan pangan secara kualitatif juga telah melampaui target, hanya sebesar tahun 2005 yang belum mencapai target. Realisasi konsumsi pangan secara kuantitatif telah melampaui target setiap tahunnya, sedangkan secara kualitatif hanya mencapai target tahun 2005 dan 2007 yang belum mencapai target. Tren ketersediaan pangan dan realisasi konsumsi secara kuantitatif menurun, sedangkan target yang dicapai tren meningkat. Ketidaksesuaian antara realisasi dan target secara kuantitatif mungkin dipengaruhi oleh faktor penawaran dan permintaan pangan dibandingkan dengan perencanaannya. Meski begitu, realisasi ketersediaan pangan sudah mampu untuk memenuhi realisasi konsumsi pangan masyarakat di Kabupaten Muara Enim.

Judul: Perencanaan ketersediaan pangan berkelanjutan di Kabupaten Muara Enim Provinsi Sumatera Selatan
Abstrak: Food security is a mandatory government affairs. It requires some forms of development planning in order to guarantee a sustainable food security. Food and nutrition planning as part of regional development planning is made to improve the quality of human resources and economic development, which is not solely on the planning of food commodities. One of targets to be achieved is the amount of food availability (in the form of daily energy availability of 2.200 kcal/capita) as well as the diverse on the basis of balanced nutrition that is indicated by a desirable dietary pattern or pola pangan harapan (PPH) score of 100. Muara Enim distric does not currently have a reference for the operational targets of food production to meet the ideal food consumption and land area that should be provided to ensure sustainable food supply. Therefore, the main objective of this research is to analyze the carrying capacity of the region to plan a sustainable food supply in Muara Enim regency. This was retrospective study. Research location was in Muara Enim regency in South Sumatra Province, and the study location were selected on purpose (purposive). The experiment was conducted in September through October 2010. The results showed that 1) the potentials for food production were varied and could be developed to meet the food consumption of the population, 2) some adjustments between production targets of satuan kerja perangkat daerah (SKPD) and ideal food consumption needs of the population were required, 3) agricultural land to be preserved for food is 115,043 ha (wetland 36,539 ha and 80,371 ha of dry land, with land man ratio of 1,420 m2/capita), and 4) sharpening is needed in the synchronization between planning documents and development objectives in quantitative determination.

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.
