Judul: Analisis Faktor Ekonomi yang Mempengaruhi Laju Inflasi Negara Anggota ASEAN dengan Regresi Data Panel
Abstrak: Panel data regression model is the regression model using panel data which is a combination of cross section data and time series data. To estimate the panel data regression model, there are 3 approaches, those are pooled least square, fixed effect model, and random effect model. Parameters on pooled least square approach be estimated by Ordinary Least Square (OLS) method. On fixed effect model approach, parameters be estimated by OLS with the addition of dummy variable. Parameters on random effect model be estimated by Generalized Least Square (GLS). This research aims to estimate the panel data regression model to the data rate of inflation percentage of ASEAN member countries in 2000-2008 to know the economic factors that affect the inflation rate. The results of panel data analysis shows that the appropriate panel data regression model for these data is the fixed effect model with weighting (cross section weights) and white heteroscedasticity. This model indicates that the Consumer Price Index and money growth significantly affected the inflation rate of the ASEAN member countries.

Judul: Analisis Dampak Inflasi terhadap Pertumbuhan Ekonomi di Negara ASEAN+5
Abstrak: Negara ASEAN+5 menunjukkan perkembangan inflasi dan pertumbuhan ekonomi yang berbeda-beda. Terdapat pola hubungan antara inflasi dengan pertumbuhan ekonomi. Ada saat peningkatan inflasi diikuti dengan menurunnya laju pertumbuhan ekonomi ataupun sebaliknya. Peningkatan inflasi dibarengi dengan peningkatan pertumbuhan ekonomi maupun sebaliknya. Hal ini menarik untuk dianalisis lebih lanjut. Tujuan dari penelitian ini adalah untuk menganalisis dampak inflasi terhadap pertumbuhan ekonomi di negara ASEAN+5. Periode analisis yang digunakan dalam penelitian yaitu dari tahun 1995-2014 dengan menggunakan metode Fixed Effect Model panel statis. Hasil penelitian menunjukkan bahwa terjadi dampak negatif antara inflasi dan pertumbuhan ekonomi di negara ASEAN+5. Oleh karena itu bank sentral harus menjaga tingkat inflasi agar tidak menghambat laju pertumbuhan ekonomi di negara ASEAN+5. Serta melakukan peningkatan kerja sama dalam keterbukaan perdagangan seperti perdagangan internasional dan pembentukan modal melalui investasi. Diharapkan dengan hal itu dapat meningkatkan laju pertumbuhan ekonomi di negara ASEAN+5.

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.
