Judul: Development of agropolitan policy model based on regional sustainable agribusiness livestock In Jayapura Regency
Abstrak: Agropolitan estate development in the Regency of Jayapura is less sustainable. Of the five dimensions are analyzed to determine the status of sustainability of regional development, there are two dimensions that are categorized as showed quite sustainable (score 50-75), namely the economic dimension with a value of 53.2 index; and social dimensions (67.0). While the dimensions are less sustainable (score <50) is the dimension of ecology with an index value of 48.5; dimensions of technology (40.5), and institutional dimensions (49.3). The dimensions of ecological, technological, and institutional become the most important thing to consider in the development activities agropolitan Jayapura region because it has a sustainability index score <50. There are five key factors to consider in order to meet the future needs of stakeholders in the development of region-based agropolitan beef cattle in Jayapura District, namely: the improvement of maintenance systems, facilities and infrastructure development of agribusiness, the construction of artificial insemination post, the availability of financial institution that provides easy-interest loans lower for beef cattle raising business capital and the support of local government policy in the form of changes in budget revenues and expenditures livestock sub-sector. The design of development policies formulated by taking into account the area agropolitan key factors that have been generated from the preceding analysis. It also include the results of regional development policy review agropolitan. The formulation of this policy is carried out through FGDs with stakeholders and experts. The formulation of regional development policy design agropolitan are: (1) Improving the quality of human resources, especially farmers and ranchers farm actors through training and education, (2) Development and maintenance of infrastructure and facilities for the region to support the development of the region, (3) Increasing the number of beef cattle traded with agricultural commodities that can improve the welfare of the community, (4) Developing and strengthening partnerships in support of farming beef cattle agribusiness development activities, (5) Improvement of investment climate and increased government investment and entrepreneurs, and (6) Development of cultivation technology and the improvement of agriculture and animal husbandry agricultural business management. Regional development policy alternatives agropolitan continuing the priorities are: improving and strengthening partnerships in support of agribusiness farm commodities of superior livestock. To realize the policy is agreed upon policy implementation strategy are: to develop quality human resources in the region in strengthening the partnership agropolitan, implement construction and maintenance of facilities and infrastructure to support increased business and investment partnerships, developing economies in the region mengintensitaskan agropolitan with beef cattle population and productivity agriculture that can support business partnerships in accelerating economic growth and implement policies to improve the system of business partnerships and rental growth in the financial sector as a source of capital that can contribute to the welfare of the community by conducting inter-regional cooperation in promoting the growth of industrial sector in the region through efforts to increase the power industrial competitiveness by developing a network pattern of industrial clusters as its foundation.

Judul: Model of sustainable agropolitan region development based on animal husbandry at Situbondo
Abstrak: Rural development for Situbondo Region which based on agriculture and animal husbandry is Agropolitan Region based on animal husbandry. The purposes of this research were (1) to identify the potency, development level, and sustainability of The Situbondo Region. 2) to develop a model of sustainable agropolitan region based on animal husbandry; and 3) to formulate policy direction and strategy of agropolitan development. Research conducted at some areas of the ranch based in Situbondo, namely: Asembagus, Jangkar, Arjasa, Kapongan, and Mangaran. Types of data analysis applied in this study were location quotient (LQ) analysis, analysis of superior and leading commodity, the analysis of farming, analysis of area typology, principle component analysis (PCA), cluster analysis, scalogram analysis, and analysis of centrality, multidimensional scaling (MDS), prospective analysis, and dynamic system analysis. The results showed that Situbondo Region had some bases commodities on farm such as: beef cattle, sheep, goats, and ducks. Cattle production (fattening) as a leading commodity gives highest profit for farmer (Rp 4 250 000,-/head/year). Situbondo Region also constitutes Pre-Agropolitan II category; including 4 villages at advanced level, 17 villages at medium level and 21 villages at low level of growth development. From the sustainability analysis which analysed 73 attributes only 24 attributes are sensitive to the value of sustainability index based on farms area. Considering status of eco-dimensional (46.50%), technology of infrastructure (45.48%), and institutional (47.46%) showed the status of less sustainable, whereas the economic dimensions (69.53%) and socio-cultural (55.14%) showed quite sustainable condition. Focussed on repairing these sensitive attributes that affected sustainability, it can improves the sustainability status for future scenarios. With dynamic system analysis, we can find out that up to 2025, the population patterns tends to grow positively and exponentially, while agropolitan productions and farming profits have the same patterns until at one point, will moves to an equilibrium point (stable conditions) because of the “limit to growth” processes (archetype). Therefore, optimistic scenarios with great intervention on one or more affected variables need to apply to increase the model performance. Finally, Situbondo development policies should based on The County Farm by forming Village Growth Center and hinterland completed with facilities and infrastructures, actuation commodity diversification and home industries breeders, improvement production through extensification and intensification, fostering economic and social institutions, entwining partnership between stakeholders, and capability improvement of human resources especially for the breeders.

Judul: Karakterisasi Optik dan Listrik Film LiTaO3 (Lithium Tantalate) pada Substrat Silikon [Si(111)] Tipe-n/n+
Abstrak: Telah berhasil dibuat film LiTaO3 pada substrat silikon [Si(111)] tipe-n/n+ dengan variasi suhu annealing selama 8 jam pada suhu 550 oC, 575 oC, 600 oC, dan 625 oC. Metode yang digunakan yaitu Chemical Solution Deposition (CSD) dengan spin coating berkecepatan putar 3000 rpm selama 30 detik dalam kelarutan 1 M. Analisis energi band gap menggunakan metode Tauc Plot menghasilkan nilai sebesar 2.59 - 2.72 eV. Hasil analisis XRD untuk film LiTaO3 pada suhu annealing 600 oC menunjukkan bahwa struktur kristalnya membentuk hexagonal dengan parameter kisi a = b = 5.199Å dan c = 13.890Å. Hasil uji optik menunjukkan bahwa film LiTaO3 dapat mengabsorbsi spektrum Inframerah dekat dengan transisi indirect. Hasil uji listrik menunjukkan bahwa film LiTaO3 termasuk material semikonduktor
