Judul: Analisis Strategi Pengembangan Usaha Sayuran Organik Pada Kelompok Tani Cibolerang Agro Kecamatan Selaawi-Kabupaten Garut
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: Analisis Strategi Pengembangan Usaha Sayuran Organik pada Kelompok Tani Sugih Tani pada Kawasan Agropolitan di Desa Karehkel, Kecamatan Leuwi Liang, Kabupaten Bogor
Abstrak: Semakin meningkatnya tingkat pendidikan dan kesadaran masyarakat akan pentingnya kesehatan, didukung dengan visi ”Go Organik 2010”, membuat pertanian organik semakin berkembang beberapa tahun belakangan ini. Salah satunya yaitu pada Kelompok Tani Sugih Tani di Desa Karehkel, Kecamatan Leuwi Liang, Kabupaten Bogor. Untuk dapat mengembangkan usaha sayuran organiknya, kelompok tani Sugih Tani memerlukan suatu perumusan strategi yang tepat dengan memanfaatkan kekuatan dan peluang untuk meminimalisir kekurangan dan ancaman yang dihadapi. Tujuan dari penelitian ini yaitu: (1) Menganalisis faktor-faktor internal dan eksternal yang menjadi kekuatan, kelemahan, peluang dan ancaman pada Kelompok Tani Sugih Tani, (2) Merumuskan alternatif strategi pengembangan usaha yang tepat untuk diterapkan oleh Kelompok Tani Sugih Tani, (3) Memilih strategi pengembangan usaha yang tepat untuk Kelompok Tani Sugih Tani. Data yang digunakan adalah data primer dan data sekunder, melalui observasi, wawancara dan studi literatur. Proses penentuan strategi dilakukan melalui matriks IFE, EFE, SWOT, dan QSP. Analisis data menggunakan Microsoft Excel dan alat hitung kalkulator. Berdasarkan hasil analisis faktor internal, Kelompok Tani Sugih Tani memiliki posisi internal yang lemah (2,420). Kekuatan terbesar kelompok tani adalah faktor sudah memiliki pasar tetap (0,383). Sedangkan kelemahan utama yang dimiliki oleh Kelompok Tani Sugih Tani yaitu belum diterapkannya SIM dalam sistem manajerial (0,052). Berdasarkan hasil analisis faktor eksternal, Kelompok Tani Sugih Tani sudah memiliki kemampuan yang cukup tinggi dalam memanfaatkan peluang dan mengatasi ancaman yang ada (2,973). Peluang utama kelompok tani adalah faktor kebijakan pemerintah mengenai ”Go Organic 2010” dan dukungan untuk mengembangkan pertanian organik (0,315). Sedangkan ancaman utama yang dimiliki oleh Kelompok Tani Sugih Tani yaitu jaringan distribusi dan pemasaran pesaing sudah lebih luas (0,288). Berdasarkan hasil analisis matriks SWOT, terdapat enam alternatif strategi yang dapat dikembangkan berdasarkan startegi SO, WO, ST, dan WT. Alternatif strategi terpilih yang sebaiknya diterapkan oleh Kelompok Tani Sugih Tani yaitu mengoptimalkan upaya pengendalian mutu pada produk dan pasar yang sudah ada (STAS = 5,776), dengan upaya yang sebaiknya dilakukan yaitu pembinaan kemampuan teknis petani, menggunakan bibit unggul, pupuk yang berkualitas, pengendalian hama terpadu dan pembuatan atau penggunaan pestisida organik yang efektif bagi hama, serta mengecek kondisi tanah.

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.
