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

Judul: Analisis Faktor-Faktor yang Mempengaruhi Pengeluaran Pemerintah Indonesia (
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: Synthesis of Biphasic Calcium Phosphate Made of Eggshells Through A Hydrothermal Method
Abstrak: Biphasic Calcium Phosphate mixed of hydroxyapatite and tricalcium phosphate. A hydrothermal method of synthesizing by mixing CaO as calcium source and (NH4)2HPO4 as phosphate source with distilled water. CaO got from calcination process made of eggshells. All samples were synthesized using hydrothermal reactor then followed by sintering process. The molar ratio of Ca and P for all samples was 0.5 M : 0.3 M. Hydrothermal temperature and sintering temperature were variated they are 250 ºC, 300 ºC for hydrothermal and 800 ºC, 900 ºC, 1000 ºC for sintering, higher treatment temperature, tricalcium phosphate appears. Final results of synthesis were characterized by using X-ray Diffraction and Fourier Transform Infrared. X-ray Diffraction patterns was ecompared with database Join Committee on Powder Diffraction Standards and found tricalcium phosphate and hydoxyapatite.
