Faktor-faktor yang Mempengaruhi Cadangan Devisa dan Net Ekspor di Indonesia

This study aims to analyze and determine (1) the influence of net exports, foreign debt, FDI, and foreign reserves previously period against reserves in Indonesia. (2) the influence of the economy, the economy and the foreign exchange rate on net exports in Indonesia. This study using a simultaneous equations model analysis with Indirect Least Squared method (ILS) from the first quarter of 2000 - the fourth quarter of 2011. The research concludes that (1) Net exports, external debt and International reserves prior period reserves in Indonesia affected significantly. While the FDI variable does not affect reserves in Indonesia are significantly (2) Indonesia\u27s economy, the Japanese economy and the exchange rate significantly affects net exports in Indonesia. Based on these results the policies recommended to the government of which the export should be developed by the excess exports over imports would benefit the government by increasing foreign exchange reserves, the need to foster a harmonious working relationship with trading partners, the need for trade policy strategy, especially in partner mediversifikasi major trading for export

Hydrophobicity properties of graphite and reduced graphene oxide of the polysulfone (PSf) mixed matrix membrane

Hydrophobicity properties of graphite and reduced graphene oxide (rGO) (from exfoliated graphite/rGO) towards PSf polymer membrane characteristic and properties at different additives weight concentrations (1, 2, 3, 4 and 5 wt. %) were investigated. Both PSF/graphite and PSf/rGO membranes were characterized in term of hydrophobicity, surface bonding, surface roughness and porosity. FTIR peaks revealed that membrane with graphite and reduced graphene oxide nearly diminished their O-H bonding which was opposite to the graphene oxide peak that shows a strong O-H bonding as increased exfoliated times. These results were in line with the contact angle results that showed strong hydrophobicity of graphite and reduced graphene oxide membranes as increased these additives concentration. The effect of strong hydrophobicity in these membranes also has resulted in smoother surface roughness compared to pristine PSf membrane. Further investigation of the performance of water flux also proved that both above membranes have strong hydrophobic effect, with the lowest pure water flux rate (L/m2h) was given by PSf/rGO 3% membrane at 19.2437 L/m2h

RETRACTED: Monolayers of pigment-protein complexes on a bare gold electrode:Orientation controlled deposition and comparison of electron transfer rate for two configurations

Photosynthetic protein complexes are very efficient in solar energy absorption, excitation transfer, and subsequent electron transfer. These complexes have the potential to be exploited as circuit elements for various bio-hybrid devices, ranging from biosensors to solar cells. In this report, we characterized a bioelectronic composite fabricated by interfacing reaction center-light harvesting 1 (RC-LH1) complex with an un-functionalized gold surface in defined orientation. The orientation of RC-LH1 complex was controlled by using Langmuir-Blodgett (LB) deposition technique: RC-LH1 complexes were attached to the electrode facing either with their primary donor or the acceptor sides by'"forward" or'"reverse" dipping, respectively. Photochronoamperometry was utilized to confirm the integrity of the protein complexes and their orientation. Electrical transport of protein complexes coupled to gold electrode was studied by using conductive atomic force microscopy (C-AFM). Two distinct current-voltage (I-. V) curves were observed for two different deposition schemes, indicating opposite orientations of RC-LH1 complexes on the electrode. I-. V spectroscopy was also carried out under light illumination, the magnitude of current was considerably increased by the light illumination and the asymmetry of the curves was more pronounced. We show that, RC-LH1 complexes attached to the electrode with primary donor side facing the electrode exhibit much faster electron transfer compared to opposite orientatio

The study aimed to examine the effect of management ownership on risk management disclosure, the effect of institution ownership on risk management disclosure, the effect of capital structure on risk management disclosure and the effect of firm size on risk management disclosure. The sample was taken using the method of purposive sampling from banking firm listed Indonesian Stock Exchange(BEI) in 2010-2012. The sampling used was of 108 samples from 36 banks period of 3 years. The method of analysis in this study using multiple regression. The results of this study indicate that firm size effect on risk management disclosure. While management ownership, institution ownership, and capital structure does not effect on risk management disclosure

UV-VIS spectral evaluation of CR-39 detector exposed with diagnostic dosage

The effects of the X-ray irradiation and chemical etching on the physical and optical properties of CR-39 plastic detectors were investigated for different doses of X-ray. CR-39 detectors were etched in the solution of the 3 M of NaOH after irradiation for revelations of the track. The tracks formed on CR-39 either by irradiated X-ray or due to the effect of environment. The changes in the thickness after exposed have significant decrease in 60 kVp and started to increase in the range of 70 kVp up to 100 kVp due to the formation of oxidation layer on surface by free radicals. The optical band gaps before etching and after etching were determined by using Ultraviolet-visible (UV-Vis) spectroscopy. The optical band gap is attributed to the indirect transition due to its amorphous nature which is significantly decline trend energy in increase of the energy fluence of radiation. The Urbach’s energy, is defined as the width of the tail localized states in the forbidden band gap which change increment trend as increase in dose delivered due to the distortion structure of the CR-39 in terms of the electron charges in valences electron hence attributes to the induced modification of angle bond between the neighboring atoms
