Judul: Analisis Dampak Variabel Makroekonomi terhadap Defisit Anggaran Pemerintah di Indonesia
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan jangka panjang antara variabel makroekonomi dengan deficit anggaran pemerintah dan juga menganalisis variabel makroekonomi yang memberikan dampak paling besar terhadap defisit anggaran pemerintah di Indonesia. Metode analisis yang digunakan dalam penelitian ini yaitu metode VECM. Variabel yang digunakan yaitu defisit anggaran pemerintah (DAP), pertumbuhan ekonomi (PDB), inflasi (INF), nilai tukar (NEER), suku bunga (SB), Harga Minyak Mentah (COP), dan Produksi Minyak Nasional (Oil) dengan periode waktu penelitian ini yaitu tahunan dari tahun 1980 hingga 2013. Hasil penelitian ini menunjukan bahwa defisit anggaran pemerintah memiliki dampak yang paling besar terhadap defisit anggaran pemerintah itu sendiri. Hal tersebut menunjukan bahwa defisit anggaran pemerintah saat ini sangat diperuhi oleh defisit anggaran pemerintah periode sebelumnya. Kemudian nilai tukar dan inflasi juga memiliki dampak yang cukup besar terhadap defisit anggaran pemerintah dibanding variabel makroekonomi lainnya

Abstrak: Indonesia is one of the ASEAN countries are experiencing economic growth every year. In 2008 when the current world financial crisis GDP growth in Indonesia has decreased at least compared to other ASEAN countries. This is because the amount of consumption of Indonesia has a major influence on the economy of Indonesia. Economic growth in Indonesia is directly proportional to the Indonesian government spending. Indonesia government spending has increased every year. Increased government spending each year Indonesia Indonesia's economy even cause the budget deficit. Where government spending is greater than government revenues. Government revenue derived from the tax could not afford the amount of government spending. The purpose of this study was to analyze the relationship between economic growth in Indonesia by the Indonesian government expenditure and also analyzes the factors that influence the increase in government spending in Indonesia. The method of analysis used in this study is a method of VAR and VECM. The variables used in this study is variable spending (G), economic growth (GW), exchange rate (ER), inflation (INF), investment (INV), net exports (NE), and tax revenue (TR). The time period used in this study was the period/year 1984 to 2011. Based on this research, in the short term tax revenue, exchange rate, inflation has a positive, but not significant. While variable net exports and GDP growth has a positive and significant. In the long term variable rate (ER), net exports (NE) and GDP growth (GW) and a significant negative effect on government spending. While the inflation variable has a positive and significant impact on government spending. IRF outcome variables that describe the response of macroeconomic variables such as inflation, exchange rates, investment, GDP growth, net exports or the balance of trade, tax revenue to government spending shocks. The results show that a variant FEVD government spending predominantly explained by the variable itself from the beginning of the period until the end of the period. FEVD results also showed that the variables that contributed greatly to shocks in government spending is the exchange rate, inflation and GDP growth in the country of 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.
