Abstrak: Penelitian ini bertujuan untuk (1) Menganalisis lingkungan internal dan eksternal yang terkait dengan produksi sayuran yang aman dikonsumsi (Prima III) bernilai tambah tinggi dan berbasis petani di Pangalengan, Kabupaten Bandung; (2) Menyusun strategi produksi sayuran organik bernilai tambah tinggi berbasis petani di Pangalengan, Kabupaten Bandung. Pengumpulan data penelitian dilakukan dengan purposive sampling, yang melibatkan 10 orang responden yang terdiri dari 4 (empat) orang tenaga ahli dari Dinas Pertanian Tanaman Pangan Provinsi Jawa Barat, 2 (dua) orang Ketua Kelompok Tani di Kecamatan Pangalengan, 3 (tiga) orang pelaku usaha sekaligus pembina beberapa kelompok tani di Kecamatan Pangalengan, dan 1 (satu) orang perwakilan masyarakat pengguna sayuran organik (Ibu Kepala Desa Pangalengan). Sedangkan penentuan strategi prioritas melibatkan Kasi Teknologi Subdit Budidaya Tanaman Sayuran, Direktorat Jenderal Hortikultura Kementerian Pertanian RI. Data yang digunakan dalam penelitian ini adalah data primer dan sekunder. Data primer diperoleh dari penelitian lapangan dengan teknik interview, observasi dan kuesioner. Data sekunder diperoleh dengan cara melakukan studi pustaka (library research) seperti buku, jurnal ilmiah, laporan penelitian, atau data statistik yang tersedia di instansi pemerintah. Hasil perhitungan matriks Internal Factor Evaluation (IFE) menunjukan sayuran yang diproduksi aman dikonsumsi (skor 0,282) merupakan kekuatan utama dalam strategi produksi sayuran organik di Pangalengan dan kelemahan utama dari sistem pertanian organik adalah lemahnya akses kelompok tani terhadap pasar sayuran organik, serta keterbatasan modal (skor 0,088). Hasil analisis External Factor Evaluation (EFE), peluang utama bagi kelompok tani untuk menerapkan pertanian organik adalah harga sayuran organik lebih tinggi (skor 0,313) dan ancaman utama yang dihadapi dalam produksi sayuran organik di Pangalengan adalah iklim dan cuaca yang tidak menentu mempengaruhi hasil produksi (skor 0,183).

Judul: Strategi Persiapan Pengembangan Rantai Pasok Sayuran Organik Bernilai Tambah Tinggi Berbasis Petani di Kecamatan Pangalengan, Kabupaten Bandung
Abstrak: Healthy lifesyle with the slogan “Back to Nature” has become a new trend of the society. Directorate of Processing and Marketing, Ministry of Agriculture in Indonesia has initiated the program "Go Organic 2010" to improve the quality of life and the natural environment of Indonesia and to encourage the development of organic farming and sustainable competitiveness. Supply Chain Management (SCM) has represented overall management of agricultural activities which involved of processing, distribution, marketing, until the desired product to consumer. Stages of study included: (1) Identify the characteristics of the vegetables, the supply chain actors, and descriptive analysis of the environmental conditions in Pangalengan; (2) Identify internal and external factors; (3) The formulation of the strategy with the matrix Strengths, Weakneses, Opportunities, Threats (SWOT); (4) Selection of priority strategy. The data was collected through purposive sampling technique which involving 10 respondents and 3 experts. The data used was primary and secondary data by direct interviews, questionnaires and literature study. Selection of strategic alternatives conducted using Analytical Hierarchy Process (AHP) with Expert Choice of AHP software. The result showed that the supply chain actors of vegetables in Pangalengan were seed suppliers, farmers, traders/collectors, the company, the seller/exporter, foreign markets, traditional market and retail/supermarket. Internal Factor Evaluation (IFE) and External Factor Evaluation (EFE) analysis showed that the average total score of IFE and EFE were 2.260 and 2.790. The score represented that the ability of the farmer in utilized the strengths and the opportunities then in covered the weaknesses and the threats were on the average. The study showed that the safety of vegetables to consumer (score 0.336) was the main strength and the main weakness organic farming in Pangalengan was limited of financial (score 0.127). Futhermore, supporting of government was the major opportunity (score 0.127) and the major threat was uncertain of climate and weather which affected in production (score 0.144). Based on the formulation of strategic, the study obtained 7 (seven) strategy. The first and the second priority strategic related of the marketing, were expanding market/distribution to bussines partnerships (score 0.205) and researching of development in the organic vegetable‟s market (score 0.180). The third alternative strategic was supporting of government (score 0.157) which retaled to supervision strategy. Moreover, the fourth and the fifth alternatives related to strategy of financial, were monitoring and overseeing prices (0.156) then strengthening of financial aspects (score 0.114). The sixth and the seventh alternatives related to production management strategy, were planning a better farming (0.107) and improving the quality, quantity and continuity of production (score 0.081).

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.
