Abstrak: Vegetables are one of the important horticulture commodities in fulfilling human needs because they contain different vitamins, provitamin, minerals, fiber, carbohydrate, antioxidant and antibacterial substances which are useful for human health. In this modern era, a healthy life style or more populary known with a slogan “back to nature” has been increasingly practiced by people. Many people have realized about the importance of keeping health by decreasing the consumption of foods that are harmful to the body, especially vegetables which contain chemical substances such as chemical fertilizers and pesticides. The people’s awareness of going back to nature in agricultural sector is supported by the government through Directorate of Processing and Marketing of Agricultural Products by initiating “Go Organic 2010” program which has been developed since 2001. The increase in the demand for organic vegetables shows that organic vegetable business has a good potential and opportunity to be developed to make organic agriculture to be more competitive and sustainable. Garut regency is one of the regencies in West Java which has a big potential in vegetable development. There is one farmer group (Poktan) in Selaawi subdistrict which has pioneered organic vegetable agriculture, that is, Poktan Cibolerang Agro (Cibo Agro) which was established in 2009. In 2011, Poktan Cibo Agro got a certificate of organic food from Indonesian Organic Farming Certificate (Inofice). This research is part of National Research Strategy entitled Production Strategy of Organic Food with Agriculture-Based High Added Value in West Java. The objectives of this research were 1) to identify and describe the production process of organic vegetables, 2) to identify and study internal as well as external factors related to the development of Cibo Agro organic vegetables and 3) to formulate strategies for effective business development of organic vegetables for the group of farmers Cibo Agro. Analysis tools used in this research were Internal Factor Evaluation (IFE), External Factor Evaluation (EFE), Internal External Matrix (IE), Strengths, Weaknesses, Opportunities and Threats (SWOT) and Analytical Hierarchy Process (AHP). The result of IFE matrix calculation showed that in the strength factor, package factor and label factor were in the first rank (0,448). In the weakness factor, the absence of contract with suppliers had the highest weighted score (0,149). The total score weight was 2,231. The result of IFE matrix calculation showed that opportunity that was in the first rank with a weighted score of 0,551 was the establishment of organic agriculture association. In the threat factor, uncertain climate and weather had the highest weighted score of 0,268 and became a big threat for Cibo Agro farmers. The total weight score was 2,880. The AHP result showed that in Factor Level what became the first priority in the achievement of strategy focus of organic vegetable business development of Ciba Agro was the market potential with a weight of 0,269. In Actor level, what was the first priority was ICS Cibo Agro with a weight of 0,413. In Objective Level, the increase in farmer income became the first priority in strategy of organic vegetable development (the weight: 0,372). The priority strategy alternative which was obtained

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.
