Judul: Analisis Pengaruh Foreign Direct Investment (FDI) terhadap Perekonomian Indonesia
Abstrak: Foreign Direct Investment (FDI) memiliki peranan penting dalam perekonomian Indonesia dari sisi permodalan atau investasi. Nilainya terus meningkat setelah krisis ekonomi tahun 1998. Tujuan dari penelitian ini adalah menganalisis pengaruh Foreign Direct Investment (FDI) dan faktor-faktor yang mengaruhi perekonomian di Indonesia. Data yang digunakan adalah data time series tahunan periode tahun 1990 sampai 2014. Metode yang digunakan adalah metode Ordinary Least Square (OLS) untuk mengestimasi koefisien-koefisien regresi menggunakan estimator yang jaraknya minimum. FDI, inflasi, politik, dan teror berpengaruh positif signifikan. Hutang berpengaruh negatif signifikan terhadap perekonomian, sedangkan total perdagangan dan tabungan tidak berpengaruh signifikan terhadap perekonomian Indonesia. Oleh karena itu, diperlukan peningkatan permodalan dari sisi tabungan dan surplus perdagangan untuk meningkatkan perekonomian Indonesia.

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.
