Judul: The Influence of Infrastructure on Regional Economic Growth and Poverty in Eastern Indonesia.
Abstrak: Proses pertumbuhan ekonomi dapat dipengaruhi oleh berbagai faktor salah satunya ketersediaan infrastruktur yang baik dan memadai sehingga dapat memberikan efek yang berkelanjutan terhadap pengentasan kemiskinan. Penelitian ini dilakukan untuk menganalisis pengaruh infrastruktur terhadap pertumbuhan ekonomi wilayah dan kemiskinan di Kawasan Timur Indonesia (KTI) periode 2010-2015. Data yang digunakan dalam penelitian ini adalah data sekunder yang diperoleh dari BPS, Kementerian kesehatan dan literatur lainnya yang relevan. Metode analisis menggunakan metode pendugaan Two Stage Least Square (2SLS) dengan analisis persamaan simultan, menggunakan data panel dengan time series tahunan dari 2010 sampai dengan 2015 dan cross section 16 provinsi di Kawasan Timur Indonesia. Variabel infrastruktur (jalan, listrik, dan PAM) tidak elastis dalam memengaruhi PDRB riil dan variabel PDRB riil juga tidak elastis dalam memengaruhi jumlah penduduk miskin di KTI. Hal tersebut dikarenakan di KTI tidak seluruh provinsi memerlukan pemenuhan infrastruktur yang cepat dan sama jenisnya, masing-masing provinsi memiliki kebutuhan yang berbeda. Oleh karena itu infrastruktur tersebut tidak secara otomatis memengaruhi PDRB riil maupun jumlah penduduk miskin.

Judul: Dampak Pembangunan Infrastruktur dan Aglomerasi Industri terhadap Pertumbuhan Ekonomi Regional di Indonesia
Abstrak: In general, the Indonesia’s economic growth is significantly improved recently but the increase rate is different in each region which entitles to high regional disparity. One of the reasons why it occurs is because of the difference of infrastructure development in every region. Beside, the centralization of the economic activities tends to cause this issue. This study intends to analyze the effect of infrastructure development and industrial agglomeration to the regional economic growth in Indonesia. Based on productivity function of Cobb-Douglas model, the fixed effect model is used as data panel method which includes a range of data from 26 provinces in 1991-2007. The estimation in this study ensues to the influence of labor, investment, human capital, physical infrastructures (electricity and roads), industrial agglomeration, and economic crisis in 1997, while water infrastructure is not significant. Due to the estimation data result, the characteristic of production activity in Indonesia is labor-based with the labor elasticity rate of 0,27 higher than investment elasticity which is 0,10. Human capital variable holds the biggest effect with 0,34 score. Physical infrastructure (electricity and roads) is significantly influential with electricity elasticity indicates 0,33 score, higher than roads elasticity score of 0,13. In addition to this, industrial agglomeration contributes positive effect on economic growth which is indicated by 0,04 elasticity score. On the other hand, the negative coefficient score as a result of economic crisis in 1997 obstructs the economic growth. To sum up, variables which deliver positive influence for regional economic growth in Indonesia are human capital, electricity, roads, and industrial agglomeration. Furthermore, distribution of infrastructure development, education, and centralization of the economy activity should be applied in order to reduce regional disparity.

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.
