The purpose of this study to obtain empirical evidence about the detection of the capital structure of the research is a qualitative approach. The analysis tools are descriptive to explain deficit financing by following formula made by Fama and French (2005). The study population was the Telecommunications Industry. The research sample was PT. Telecommunications, Tbk. Object of study is the issuer\u27s financial statements in the Indonesia Stock Exchange, PT Telkom Tbk. Observation period between 1993 to 2010. The unit of analysis is a PT. Telekomunikasai, Tbk.The content in an easy and practical periodical and time series.Design results showed growth in net assets during the period between 1993 to 2010 to increase the high trend. Leverage enterprise sxampai period between 1993 to 2008 showed an average Debt to Equity Ratio (DER) is greater than 1 (one), which means that capital structure under normal conditions and good. Meanwhile, the period between 2008 to 2009 showed that companies tend not to exist in a state of long-term debt, as well as the composition of the capital structure so filled with their own capital solvency of the company is very strong. In 2010, indicating a resurgence in the number and proportion of debt that is so small that a dominant proportion of equity in the capital structure. The results of the application detection Pecking Order Theory for PT Telecom, Tbk occurred in 1994, 1995, 1996, 1997, 1998, 2000, 2001, 2002, 2003, and 2008, 2009 and 2010. Meanwhile, in 2004, 2005, 2006 and 2007 there was no application of Pecking Order Theory.The findings showed that application of Pecking Order Theory does not always follow the growth of net assets. The implication, for the effectiveness of information Pecking Order Theory in order to enhance shareholder value, needs to study in depth by connecting to the company\u27s profitability

Efektivitas LKPD Berbasis Project Based Learning Untuk Meningkatkan Keterampilan Proses Sains Siswa

The research objective was to describe the effectiveness student worksheet Project Based Learning for improving student's science process skill. Samples were randomly selected from a population of seventh-grade students at SMPN 31 bandar Lampung in teaching year 2016-2017 where classes of VII B and VII I were chosen as experimental classes. This research method was a type of pre-posstest quasi experimental design. Data pretest, posttest and n-Gain scores were analyzed descriptively to elucidate the improvement of student's science process skills.

Implementasi Pembelajaran Berbasis Multi Representasi untuk Peningkatan Penguasaan Konsep Fisika Kuantum

Implementation of Multiple-Representation-Based Instructions to Improve the Mastery of Quantum Physics Concepts. This study aimed to design and investigate the role of multiple-representation-based instructions in the improvement of student teachers' quantum physics mastery. This study used a quasi-experimental control group pretest-posttest design as quantitative part of a mixed-methods study. The subjects were student teachers of physics in the Department of Mathematics and Science Education in a state university in Lampung Province in the 2009-2010 academic year. For assessing the quantum physics mastery, the Quantum Physics Concept Achievement Test (QPCAT) was used. The quantitative analyses were conducted using the Mann Whitney U test. The results showed that multiple-representation-based instructions had a significant effect on student teachers' quantum physics concept mastery. The results of semi-structured interviews as qualitative part of this study indicated that in the experimental group the students used a variety of representation modes in the learning process and were capable of using the most appropriate one to solve a given quantum physics concept problem

Some exact results on the matter star-product in the half-string formalism

We show that the D25 sliver wavefunction, just as the D-instanton sliver, factorizes when expressed in terms of half-string coordinates. We also calculate analytically the star-product of two zero-momentum eigenstates of $\hat{x}$ using the vertex in the oscillator basis, thereby showing that the star-product in the matter sector can indeed be seen as multiplication of matrices acting on the space of functionals of half strings. We then use the above results to establish that the matrices $\rho_{1,2}$, conjectured by Rastelli, Sen and Zwiebach to be left and right projectors on the sliver, are indeed so.Comment: 27 pages; footnote adde

Computing in String Field Theory Using the Moyal Star Product

Using the Moyal star product, we define open bosonic string field theory carefully, with a cutoff, for any number of string oscillators and any oscillator frequencies. Through detailed computations, such as Neumann coefficients for all string vertices, we show that the Moyal star product is all that is needed to give a precise definition of string field theory. The formulation of the theory as well as the computation techniques are considerably simpler in the Moyal formulation. After identifying a monoid algebra as a fundamental mathematical structure in string field theory, we use it as a tool to compute with ease the field configurations for wedge, sliver, and generalized projectors, as well as all the string interaction vertices for perturbative as well as monoid-type nonperturbative states. Finally, in the context of VSFT we analyze the small fluctuations around any D-brane vacuum. We show quite generally that to obtain nontrivial mass and coupling, as well as a closed strings, there must be an associativity anomaly. We identify the detailed source of the anomaly, but leave its study for future work.Comment: 77 pages, LaTeX. v3: corrections of signs or factors (for a list of corrections see beginning of source file
