Judul: Evaluasi dan Strategi Peningkatan Kinerja Pemasok Sayuran Organik di Agribusiness Development Station IPB
Abstrak: Peran Agribusiness Development Station (ADS) Institut Pertanian Bogor (IPB) sangat penting, terutama dalam pemenuhan kebutuhan konsumsi sayuran organik di Indonesia. Namun, pemenuhan keseluruhan permintaan pasar tidak bisa terpenuhi. Sayuran organik dihasilkan dari kebun milik ADS IPB dan menjalin kemitraan dengan pemasok yaitu petani binaan, sayuran organik yang diproduksi sendiri oleh ADS IPB hanya 30% dan sisanya yakni 70% terpenuhi dari produksi pemasok. Peran pemasok penting untuk memenuhi permintaan sayuran organik di ADS IPB. Maka perlu adanya penelitian mengenai evaluasi dan strategi peningkatan kinerja pemasok di ADS IPB. Tujuan Penelitian ini 1) Menganalisis indikator penilaian kinerja pemasok sayuran organik di Agribusiness Development Station IPB, 2) Menganalisis pemasok terbaik sayuran organik di Agribusiness Development Station IPB, 3) Menganalisis strategi peningkatan pasokan sayuran organik di Agribusiness Development Station IPB. Penelitian ini dilakukan dengan cara wawancara kepada pakar yang berjumlah tiga orang yaitu manajer produksi, manajer program dan pendampingan, dan kepala bagian pendampingan petani. Tahapan pengolahan dan analisis data dalam penelitian ini menggunakan metode analisis ABC, Analytical Hierarchy Process (AHP), dan analisis perumusan strategi yang terdiri dari analisis faktor internal dan eksternal, analisis matriks internal eksternal, analisis Strength, Weaknes, Opportunity, and Threats (SWOT). Hasil penelitian diperoleh faktor penilaian pemasok sebagai berikut. Pada faktor Quality (0.403) memiliki dua sub faktor dengan nilai bobot kepentingan sama tinggi yakni kesesuaian pasokan produk dengan standar mutu yang ditetapkan (0.202) dan kemampuan memberikan pasokan produk dengan mutu konsisten (0,202). Pada faktor Delivery (0.292), sub faktor tertinggi yaitu ketepatan jumlah pengiriman sesuai perjanjian kontrak mendapat nilai bobot (0.140). Pada faktor Responsiveness (0.305) didapat sub faktor tertinggi yaitu kemampuan memberikan informasi dengan jelas dengan nilai bobot (0,131). Dari hasil penilaian pemasok sayuran organik di ADS IPB didapat peringkat pemasok dengan bobot tertinggi menurut model AHP secara berurutan adalah Fauzi (0.249), Endang (0.217), Ujang (0.214), Leuwi Liang Grup (0.197), dan Seno (0.123). Hasil analisis strategi didapat alternatif strategi pengembangan jaringan pemasok mendapat tingkat prioritas tertinggi dengan nilai bobot 0.303.

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.
