The Optimization of Capital Structure in Maximizing Profit and Corporate Value
The purpose of this research was to determine the optimal capital structure which could maximize profits and corporate value. The used method was quantitative descriptive analysis. Moreover, the data used was secondarydata in the Jakarta Islamic Index (JII) from 2011 to 2015. The results of this research show that companies which have optimal capital structure are in line with the trade-off theory models. The capital structure is optimal if thedebt levels are to a certain extent so that the corporate value will increase. However, if the debt limit passes the certain degree, profit and corporate value will decrease. Meanwhile, pecking order theory in this research doesnot conform and cannot be said to be optimal because of the low debt level describing the opposite result with the theory as low profits
Determining the Best Arch/Garch Model and Comparing JKSE with Stock Index in Developed Countries
The slow movement of Indonesia economic growth in 2014 due to several factors, in internal factors; due to the high interest rates in Indonesia and external factors from the US which will raise the fed rate this year. However, JKSE shows a sharp increase trend from the beginning of 2014 until the second quarter of 2015 although it remains fluctuate but insignificant. The purpose of this research is to determine the best ARCH/ GARCH model in JKSE and stock index in developed countries (FTSE, Nasdaq and STI) and then compare the JKSE with the stock index in developed countries (FTSE, Nasdaq and STI). The results obtained in this study is to determine the best model of ARCH / GARCH, it is obtained that JKSE is GARCH (1,2), while the FTSE obtains GARCH (2,2), NASDAQ produces the best model which is GARCH (1,1) and STI with GARCH (2,1), and the results of the comparison of JKSE with FTSE, NASDAQ and STI are that even though JKSE fluctuates with moderate levels but the trend shown upward trend. This is different with other stock indexes fluctuated highly and tends to have a downward trend
Effects of Ti Addition on the Dielectrical Properties of a New Austenite Alloy
EFFECTS OF Ti ADDITION ON THE DIELECTRICAL PROPERTIES OF A NEW AUSTENITE ALLOY. Preparation of alloys has been carried out leading to a new type of austenite alloys designated A-1 with a composition of Fe 52.22 wt%, Ni 24.2 wt%, Cr 20.0 wt%, Si 1.0 wt%, Mn 2.0 wt%, C 0.08 wt% and Ti 0.5 wt%. The main difference compared to commercial alloys (e.g. A347) is that Ti is added as an alloying element, but no P and S. The frequency-dependent conductivity and dielectric response of this novel material have been investigated by RLC bridge impedance spectroscopy method. It was verified that the real dielectric constant κ' of these newA-1materials showawell defined dielectric behavior and shows a considerable improvement over the commercial A-347 alloywith similar composition. Both dielectric response and dielectric loss curves show frequency dispersive relaxation peaks, indicating different conduction process in the surface and in the bulk of the materials. Therefore the substitution of P and S with Ti resulting in a new austenite with different dielectric properties. These improved dielectric properties should make this new material a good candidate for use as electrical connector, but with a reduced corrosion, so the lifetime or duration of application could be extended

Characterization of Physico-Chemical Properties of Nano-Sized Moringa oleifera Seed Powder and Its Application as Natural Coagulant in Water Purification Process
Several studies stated that the seed powder of Moringa oleifera is proven effective as natural coagulant in water purification process. Through milling process using HEM, the present study developed two size of Moringa oleifera filtered seed powder, i.e. 100 mesh (MoM) and nano particle (MoN), where the measurement of which was carried out using PSA. The two size seed powder was then characterized based on physical and chemical properties to application as biocoagulant in water purification process. Characterization indicated that the size of MoM and MoN was around 2300 nm and 300 nm, respectively. The major MoM compound content was 44.65% total protein, 27.05% fat, 10.86% water content, and 3.79% ash content; while for MoN was 44.41% total protein, 26.98% fat, 9.38% water content, and 3.53% ash content. Molecul weight measurement was carried out using SDS-page and the seed powder weight ranged was around 13-28 kda and 52-63 Kda. Dissolved protein content for MoM and MoN was 0.062% and 0.290%, respectively. The optimum dosage for MoN to decrease the turbidity of ground water sample and waste water was 30 ppm and 40 ppm, respectively; while for MoM was 80 ppm and 100 ppm, respectively. MoN is more effective than MoM. Keywords: nano particle, natural coagulant, Moringa oleifera, water purification

Analisis Faktor-faktor Yang Mempengaruhi Produksi Jagung Di Kabupaten Kupang (Analysis of Factors That Influence Corn Yield in Kabupaten Kupang)
Agriculture sector is the main sector in Indonesia that can be made as one of economic growth sources. One of the commodities that can be utilized is corn. Corn (Zea mays) is the staple and substitutive food sources of the people of Nusa Tenggara Timur (NTT) however, the corn cultivation in NTT is not optimal because the corns are still planted traditionally. Many kinds of effort have been done in order to raise the corn yield in NTT. The aim of this research is to see the influence of the input variable and which input variable is the most dominant toward the corn yield. This research was held in six villages on three subdistricts in Kupang regency which was selected purposively, they were Fatuleu subdistrict, Taebenu subdistrict, and North Amfoang subdistrict. The number of farmers chosen as sample members from each subdistricts was 30.The data were collected through interview, observation, and questionnaire. In order to know the factors influencing the corn yield, the researcher used Cobb Douglas production function model.The result of the regression analysis showed that there were influence of the input variable toward the corn yield and the most dominant factors were the number of plants, pesticide, andnitrogen. The Cobb Douglas production function that was obtained was Y = (-576.723) - 301,801 X1 + 77,297 X2 + 0, 036 X3 + 5,437 X4 + 47,170 X5 + 31,095 X6 17,760 X7 +412,998 X8 + e
Rolling and Annealing Effects on Microstructure and Hardness of Commercial 405 Stainless Steel
The "cold-rolling" experiments for several values of true strain namely 5 percent, 10 percent, and 15 percent respectively have been carried out on commercial SS-405 steel samples at 350oC; the as-rolled samples were cut into several pieces in size of 10 x 10 x 5 mm3, and some pieces were annealed to 550oC for 24 hours. All samples were then mounted and polished before etching in order to observe the grain boundaries. The microstructure observation on all samples was carried out by using optical microscope (MO), meanwhile X-ray diffraction technique was employed in order to support the identification of the existing phases and to verify changes with respect to crystal orientation; the hardness tests were carried out by using Vickers micro hardness tester. The microstructure observation supported by X-ray diffraction results shows that the phase grains of rolled sample tends to take the oblong-shape, accompanied by a preferred orientation predominantly inclined toward the (110) plane. The microhardness testing results show that there has been an increase in the hardness of the as-rolled samples; Mainly because of the nearly negligible thickness of the original sample (being only 5 mm in size), the 15 percent as-rolled samples exhibits only a slight reduction in hardness compared to the 10 percent as-rolled samples; The main cause of this effect is the movement of some dislocations infiltrating the surface resulting in the reduction of the inner-stress in the bulk of the samples. In the rolled-annealed samples there is a very significant reduction in hardness compared to the as-rolled samples. Here the main cause is the recrystallization process taking place during annealing, which tends to significantly reduce the dislocations
