Judul: Analisis Pengaruh Foreign Direct Investment Terhadap Ketimpangan Pendapatan di Indonesia
Abstrak: Penelitian ini bertujuan untuk melihat dampak jangka pendek dan jangka panjang Foreign Direct Investment (FDI) dan beberapa faktor penentu lainnya terhadap ketimpangan pendapatan di Indonesia. Data yang digunakan pada penelitian ini adalah data time series tahun 1986-2013 dengan pendekatan model Autoregressive Distributed Lag (ARDL) bound testing approach to cointegration untuk melihat hubungan jangka panjang dan Impulse response functions (IRF) untuk melihat dampak guncangan pada jangka pendek dari satu variabel independen terhadap variabel dependen. Hasil penelitian menunjukkan bahwa FDI mempunyai dampak positif terhadap ketimpangan pendapatan dimana hal ini konsisten dengan penelitian sebelumnya. Dampak positif tingkat pertumbuhan FDI terhadap ketimpangan pendapatan signifikan hanya pada jangka pendek.

Judul: Analisis Pengaruh Foreign Direct Investment terhadap Ketimpangan Pendapatan di Asia
Abstrak: Foreign direct investment (FDI) sebagai aliran dana investasi asing yang masuk ke dalam negeri secara langsung melalui pendirian perusahaan asing, pembangunan pabrik, pembelian barang dan jasa, serta proses produksi di negara tujuan. Investasi dapat mendorong pertumbuhan dan pembangunan ekonomi di negara tujuan. Pembangunan ekonomi sangat erat kaitannya dengan ketimpangan pendapatan di wilayah tersebut. Ketimpangan pendapatan di wilayah tersebut dihitung menggunakan koefisien gini. Penelitian ini menganalisis pengaruh foreign direct investment terhadap ketimpangan pendapatan di 8 negara Asia yaitu Indonesia, China, Thailand, Turki, Kazakhstan, Bangladesh, India, Lebanon. Metode yang digunakan adalah analisis deskriptif dan regresi data panel. Analisis ekonometrika dengan Fixed Effect Model (FEM) menunjukkan bahwa aliran dana investasi asing langsung (FDI) memiliki pengaruh positif terhadap ketimpangan pendapatan serta pengeluaran pemerintah memiliki pengaruh negatif terhadap ketimpangan pendapatan. Saran dalam penelitian ini adalah investasi asing langsung diarahkan dalam penyerapan tenaga kerja terampil dan terdidik sehingga upah yang didapatkan mampu mengurangi ketimpangan pendapatan.

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.
