Judul: The Influence of Macroeconomic Variables on the Indonesian Stock Market Development
Abstrak: Peran pasar modal sebagai sumber pendanaan perusahaan yang berimplikasi bagi perekonomian negara bukan hanya sekedar alternatif tetapi sudah mampu menjadi sumber pendanaan utama. Diperlukan peran yang lebih besar untuk mendorong perkembangan pasar modal Indonesia agar lebih besar dan tahan terhadap berbagai guncangan. Penelitian ini menggunakan metode ARDL-ECM untuk menganalisis pengaruh faktor makroekonomi terhadap perkembangan pasar saham. Penelitian ini menggunakan kapitalisasi pasar saham untuk seberapa besar pasar saham di Indonesia. Hasil menunjukkan bahwa perkembangan pasar saham Indonesia pada jangka pendek dipengaruhi oleh lag perkembangan pasar saham, M2, credit to private sector, suku bunga riil, tabungan domestik bruto, FDI, keterbukaan perdagangan, dan krisis. Sedangkan pada jangka panjang dipengaruhi oleh M2, suku bunga ril, inflasi, FDI, dan keterbukaan perdagangan.

Judul: Impact of stock market development on Indonesian macroeconomic variables
Abstrak: Stabilitas sistem keuangan dapat mendorong beroperasinya pasar sehingga dapat meningkatkan perekonomian suatu negara. Pasar modal merupakan salah satu elemen penting dalam menjaga stabilitas sistem keuangan. Integrasi antara perkembangan pasar modal dan kondisi perekonomian menyebabkan banyak perhatian, sehingga banyak penelitian dilakukan terhadap integrasi tersebut. Penelitian ini mengevaluasi hubungan antara Indeks Harga Saham Gabungan (IHSG) dan indikator makroekonomi Indonesia. Hasil yang didapatkan dari penelitian ini adalah IHSG memiliki pengaruh yang cukup kuat terhadap peubah makroekonomi Indonesia. Ketika IHSG mengalami guncangan, beberapa peubah makroekonomi akan mengalami guncangan. Guncangan yang diberikan IHSG terhadap peubah makroekonomi hanya pada 4 periode awal sedangkan pada periode berikutnya peubah makroekonomi cenderung stabil. Berdasarkan hasil uji hubungan kausalitas, disimpulkan bahwa peubah yang memiliki hubungan 2 arah adalah peubah IHSG dan peubah IHK, peubah Indeks Harga Konsumen dan Industrial Production Index (IPI), serta jumlah uang beredar luas (M2) dan Indeks Harga Saham Gabungan., Stability of the financial system could incourage market operation so as to bush the economy of a country. The capital market is one of the important elements in maintaining financial stability. The integration between the development of the capital market and economic conditions caused a lot of attention, so a lot of research done on the integration. This study evaluated the relationship between Jakarta Composite Index (JCI) and the Indonesian macroeconomic indicators. The results obtained from this study is JCI has a strong influence on Indonesian macroeconomic variables. When JCI shocks, some macroeconomic variables will experience shock. JCI shocks given to the macroeconomic variables only at the beginning of period 4, while in the next period of macroeconomic variables tend to be stable. Based on the causality test results, it was concluded that the variables that have a two-way relationship is JCI with Consumer Price Index (CPI), Consumer Price Index (CPI) with Industrial Production Index (IPI), and broad money supply (M2) with JCI.

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.
