Judul: Dampak Pengembangan Komoditas Perkebunan Terhadap Perekonomian Provinsi Jambi
Abstrak: Jambi is one of the central of estate crop productions in Indonesia. In 2006, the Minister of Agriculture issued the Regulation about Revitalization Program. Revitalization Program is an effort to accelerate the development of smallholders through expansion, renovation and rehabilitation of tree crops. Along with minister of agriculture policy, the Jambi province activities focused on the development commodity rubber, oil palm, coconut and coffee. The purpose of this study is to identify the factors that affect the area, production, productivity, commodity prices and export in the Jambi province, on each of the commodities (rubber, oil palm, coconut, coffee and Jambi), and to analyze the impact of development of commodities on the economy of Jambi province. This study employs an econometric model consisting of 17 structural equations and 9 identity equations. This study uses secondary data is structured as pooled annual data on nine districts in Jambi province, starting 2000 until 2009. The result of this study shows the only expansion of rubber, palm oil, and coffe which can improve the economy of Jambi.

Judul: Peranan Investasi Sektor Pertanian dalam Pertumbuhan Perekonomian Provinsi Jambi: “Pendekatan Input-Output dan Analitycal Hierarchy Process (AHP)
Abstrak: This research used the input-output analysis and Analitycal Hierarchy Process (AHP) to know the role investment of agricultural sector in economic growth Jambi provinces. The research aimed: (1) analyze the level of backward and forward linkages of agricultural sector with other economic sectors; (2) analyzing the impact of the agricultural sector investment towards the establishment of output, income, and labor; (3) analyze the factors that drive the policies and decisions of investors to invest in agriculture. The analysis showed that the role of agricultural sector in the province of Jambi is a huge. It can be seen from its contribution to the formation of the structure of final demand, output and value added in the economic structure of Jambi Province in 2010. The role played by the agricultural sector is a key sector of agricultural commodities (the leading sectors) Jambi Province. In addition, the role of the agricultural sector can also be seen from the backward linkages and forward linkage on the economy of Jambi Province. Based on linkage analysis, linkage sectors have direct and indirect output to the rear is dominated by the agricultural sector both on-farm and offfarm, the sector is the sector of rubber; Industry CPO; Sawmills and Wood Processing Industry; Pinang; and Plywood Industry likes; Industrial Building Materials and Furniture of Wood; Eggs; Palm oil; Industrial Rubber, Rubber and Plastic Goods, while the agricultural sector has a direct and indirect linkages to the highest front rubber sector; other food industry sectors; rice sector, and forest products. The changes value with the highest percentage due to the impact of agricultural sector investment to the formation of the value of output, income and labor that largest is the plantation sub-sector. That has the highest level of importance in influencing the policy of investment is a infrastructure factor with the actor of the most decisive is BAPEDDA Province of Jambi.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
