Judul: Stategi Pengembangan Agroindustri Pada Kawasan Sentra Produksi Di Kabupaten Tebo, Jambi
Abstrak: Kabupaten Tebo merupakan salah satu kabupaten di Propinsi Jambi yang kegiatan ekonominya masih bertumpu pada lapangan usaha pertanian, peternakan, kehutanan dan perikanan. Berdasarkan angka produk domestik regional bruto (PDRB) atas harga berlaku lapangan usaha tersebut memberikan kontribusi terhadap pembentukan PDRB sebesar 58,92%. Kondisi tersebut menunjukkan bahwa peran dari lapangan usaha tersebut masih merupakan lapangan usaha yang dominan bagi pembangunan ekonomi daerah. Bertitik tolak dari kondisi tersebut, perlu kiranya untuk menata struktur ekonomi yang seimbang antara sektor pertanian dengan sektor industri. Dalam rangka menciptakan keseimbangan tersebut, maka pengembangan agroindustri merupakan upaya untuk menciptakan keterkaitan antara sektor pertanian dan sektor industri yang diarahkan dalam suatu bentuk keterkaitan yang meliputi: (1) antara industri pengolahan dengan sumberdaya alam dan pemasarannya, (2) antara industri pengolahan yaitu industri hulu/dasar, industri hilir dan industri kecil, (3) antara industri pengolahan dengan industri pendukungnya, antara lain industri mesin, industri agroindustri dan industri pengemasan dan (4) antara sektor industri dengan sektor ekonomi dan sektor-sektor lainnya, seperti sektor perhubungan, jasa dan perbankan. Dalam rangka mencapai hasilguna dan dayaguna tujuan tersebut, maka perlu dikembangkan pusat-pusat pertumbuhan sektor agribisnis dengan memperhatikan hal-hal sebagai berikut: (1) identifikasi jenis-jenis komoditi dan industri yang layak dikembangkan disuatu wilayah yang potensial, (2) koordinasi antar sektor industri dan sektor-sektor lainnya sebagai upaya untuk menjamin keterpaduan sistem penyediaan bahan baku, pelaksanaan produksi dan sistem pemasaran, (3) promosi dan penyediaan informasi peluang usaha kepada dunia usaha dan (4) pengembangan sistem pendukung, yang meliputi sumberdaya manusia, teknologi, prasarana fisik, sistem insentif, kelembagaan maupun jasa-jasa penunjang lainnya. dst...

Abstrak: Indonesia is an agricultural country that rich in agricultural resources. Agriculture in Indonesia is divided into five sub-sectors including food crops, plantations, forestry, fishery and animal husbandry where the plantation subsector accounted for the GDP in 2013 amounted to 17.4% (BPS 2014). The development of plantation sub-sector is one option that is quite realistic as strategic business and mainstay in the Indonesian economy with rubber which became one of the State foreign exchange earner. Indonesia rubber export destinations include the United States, Japan, Singapore, and other consumer countries. Rubber plantations in Jambi Province is smallholder rubber plantations cultivated for generations, so that the rubber has become part of the culture and customs of the people of Jambi. Rubber plantations in Jambi has an area of about 588 043 hectares, with 312 925 tons of rubber results involving more than 254 746 farmers. The development of rubber can not be separated from the various problems both from the aspect of production and marketing aspects. As for the problems faced by rubber farmers is the lack of access to price information, the low productivity of rubber, the high proportion of old rubber plantation area, though the marketing of rubber material that has not been efficient, the price is not balanced, the availability of agricultural inputs the farm level is still limited. In other words, it is not enough just to increase rubber’s productivities, but must be followed by refinement or improvement effort in the marketing system. Improvements in marketing carried out with the aim to increase the level of marketing efficiency. Therefore, supply chain required by the manufacturer to obtain a quality product so that consumers are satisfied with the output generated by the plant. Thus, the purpose of this study is to identify the channel and functions of marketing agencies smallholder rubber in Tebo regency, identify the supply chain of smallholder rubber in Tebo regency with SCN approach (Supply Chain Network) covers the structure of the supply chain, supply chain business processes, supply chain management, resources power chain, targeting the chain and supply chain performance with margin approach, the farmer's share and ᴨ/C ratio, analyze the impact of the supply chain to the fulfillment of the quality and increase the marketing efficiency of smallholder rubber in Tebo. This research was conducted in the area of smallholder rubber production centers in Tebo starting from December 2014 to February 2015. The location selected purposively based on consideration of Tebo has a rubber auction market (PLK) is active and there is also a rubber processing factory (crumb rubber) as an alternative marketing rubber by farmers. The number of farmers and respondents drawn as many as 80 people. From the research results, marketing systems smallholder rubber in Tebo regency there are four marketing channels. The first marketing channel shall be composed of rubber farmers - village traders - traders districts - wholesalers and rubber factories, the second channel involves rubber farmers - traders village - a rubber factory, a third channel consists of rubber farmers - auction markets rubber - rubber factories, and channels to four consisting

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.
