Judul: Analisis kinerja lembaga kerjasama antar daerah dalam meningkatkan skala ekonomi daerah: kajian aspek kelembagaan studi kasus kerjasama antar Daerah Banjarnegara, Purbalingga, Banyumas, Cilacap Dan Kebumen
Abstrak: Cooperation between regions is an issue that needs attention from the government because of its role in helping to solve socio-political and economical problems in the region as a result of the negative effects of regional autonomy. For this reason, this study is focused on the study of the role of inter-regional cooperation in solving the economic problem, i.e. a low scale of local economy. By taking the case of the interregional cooperation institutions of BARLINGMASCAKEB, this study aimed to: (1) identify the factors that trigger the formation of inter-regional cooperation, (2) evaluate the performance of inter-regional cooperation, (3) determine whether the formation of inter-regional cooperation is an appropriate strategy for strengthening the scale of regional economy, and (4) formulate an appropriate form of inter-regional cooperation in order to perform its functions optimally. The data analyzed in this study are of primary and secondary data. The primary data were taken from the respondents by a purposive sampling while the secondary data were collected from the documents of various institutions such as regencies in figures, the report of SKPD activities, and the reports of BARLINGMASCAKEB Regional Management. By using a descriptive analysis, game analysis, transaction cost analysis and AHP (Analytical Hierarchy Process), this study obtained the following results: (1) the motivation to form the interregional cooperation institution was to conduct a joint marketing of the economic potential at the regional level and make cooperation and synergy among the regions to enhance regional economic development; (2) the resulted performance in terms of output or outcome is still at a very low level; (3) based on the game analysis and transaction cost analysis, the establishment of inter-regional cooperation institutions was effective and efficient to improve the regional economic scale; and (4) the autonomous form of inter-regional cooperation institution was the strategy selected by expert respondents in an effort to improve the functions of inter-regional cooperation institutions.

Judul: Relationship Among Budget Structure and Tipology of Regional problems for Optimazing Regional Development Performance.
Abstrak: The financial crisis beginning in medio 1997 that led to economic turbulence has exerted a negative impact on the economic condition. This condition made development performance became quite low and instable. The misallocation of budget also influenced regional development performance. This fenomena create idea that needs a study about relationship between budget structure and tipology of regional problems for optimizing regional development performance. The purpose of the research are (1) to identify profile of development performances; (2) to measure disparity development among regencies/municipalities in the provinces of West Java and Banten; (3) to measure the correlation among budget structure, tipology problems and development performance; (4) to find principal indicators of development performance. These research use the analytical tool such as: (1) Tabulation Analysis; (2) Location Quotient; (3) Williamson's Index; (4) Correlation and (5) Natural Logarithmic Regression. The result of this research indicates that (1) The structure of economics among regencies/municipalities have led sectors in West Java and Banten. Some regencies/municipalities led in manufacture industries, such as Bekasi (82.87 percent), Bogor (49.27 percent), Purwakarta (44.80 percent), Cilegon (61.84 percent), and Tangerang (56.28 percent). Some regencies/municipalities give large contribution in agriculture sectors such as Subang (42.89 percent), Garut (40.96 percent), Cirebon (37.47 percent), Lebak (40.35 percent), and Pandeglang (36.13 percent); (2) There are lack of development among regencies/municipalities. Williamson's Indices for West Java and Banten are 0.4158 and 0.5846. The figures indicate that disparity of development in Banten is higher than that in West Java; (3) The correlation between growth of Gross Domestic Regional Product (GDRP) and illiteracy rate shows negative coefficient (-0.8) with P-Value 0.000; (4) In the whole are relationship among performance of development, structure of budget and tipology of regional problems. The regression coefficient of allocation of education budget is 0.419. Meanwhile the regression coefficient rate of illiteracy is -0.580. This model have P-Value, Multiple R and R Square respectively 0.000, 0.913 and 0.834. All of the result of the research conclude that (1) The Improving of the matching among the budget patern and tipology regional problems will optimize regional development performance (2) The available of competence human resources will speed the regional development performance.(3) The Larger contribution of education budget will increase the regional development performance.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
