Judul: Analisis Deviasi Nilai Tukar Riil ASEAN dan Dampaknya Terhadap Pertumbuhan Perekonomian
Abstrak: Nilai tukar adalah salah satu variabel krusial dalam kegiatan perekonomian internasional. Tujuan dari penelitian ini adalah menganalisis keadaan nilai tukar negara negara ASEAN terhadap kesetimbangan jangka panjang yang digambarkan dengan nilai tukar riil efektif dan mencari faktor faktor yang memengaruhi deviasi nilai tukar tersebut serta hubungannya dengan pertumbuhan perekonomian. Objek penelitian ini adalah negara negara ASEAN, namun karena ketersediaan data maka fokus penelitian tertuju pada 5 negara ASEAN (Indonesia, Singapura, Malaysia, Thailand, Filipina) dalam periode tahun 2000 hingga 2011. Hasil penelitian ini menunjukkan adanya deviasi nilai tukar senilai rata rata 14.61 persen undervalue dan deviasi secara jangka panjang dipengaruhi oleh term of trade, net foreign asset per gdp, government spending, productivity differential dan krisis yang terjadi pada 2008. Deviasi nilai tukar juga terbukti berpengaruh negatif terhadap pertumbuhan perekonomian

Judul: Analisis Dampak Infrastruktur Transportasi dan Teknologi Informasi Komunikasi terhadap Nilai Tukar Perdagangan di ASEAN dan Asia
Abstrak: Salah satu indikator perkembangan perdagangan internasional suatu negara adalah nilai ekspor dan impornya. Kemampuan mengekspor dan sebaliknya yang dilakukan oleh suatu negara akan menentukan nilai tukar perdagangan (term of trade) negara tersebut terhadap negara lainnya. Nilai tukar perdagangan menggambarkan kesejahteraan suatu negara dari perspektif perdagangan internasional. Jika nilai tukar perdagangan meningkat maka hal tersebut mengindikasikan peningkatan posisi perdagangan negara tersebut melalui kemampuan mengekspor dibandingkan dengan impornya. Nilai tukar perdagangan memengaruhi pendapatan riil suatu negara dari sisi perdagangan internasional.

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.
