Abstrak: PT Pegadaian (Persero) is a state owned company engaged in services for the general public, especially in pawn business with assurance of goods movement. To assessment the financial performance of PT Pegadaian (Persero) can be done by analyzing the financial statements. This analysis will be obtained where the strength and weaknesses of the company. This research was conducted at PT Pegadaian (Persero) and the type of data used is secondary data. The aims of this study are to identify and analyze financial development financial performance using financial ratio analysis and Du Pont, analyzing the percentage per component in the financial statements on PT Pegadaian (Persero) 2008-2012. Results of the study is the analysis of the trend toward the value of current assets, non-current assets, current liabilities and equities experienced a rising trend proves that after a change in the status of legal entity into PT Pegadaian (Persero) to be better development of the company. And the assessment categories PT Pegadaian (Persero) showed healthy predicates during 2008 until the year 2012.

Judul: Analisis Perkembangan Kinerja Keuangan pada PT. Lentera Abadi Periode 2007-2011
Abstrak: PT. Lentera Abadi is a company specializing in the publishing sector. The presence of e-book technology make this company has many competitors, thus causing the need for good financial performance in this company. To that end, the goal of this research is to determine the development of the financial performance of PT. Lentera Abadi 2007-2011 period using ratio analysis, Du Pont analysis, trend analysis, and common size statements analysis as well as to identify the factors that affect the company’s financial performance. Based on the ratio analysis and analysis of Du Pont, development financial performance on this company tend to increase every year, while based on the trend analysis of the company net profit condition would continue to decline until 2014. The results of analysis showed that the percentage per component in the period 2007-2011 for the company are more invested funds in short term investment. For internal and external factors that affect the company’s financial performance is accounts receivable as well as cooperation with other companies and sales person performance.

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.
