Assessment of economic feasibility for gridconnected renewable energy system for a household application in Terengganu

This article extends the conference paper ‘Simulation-based method to evaluate PV/wind hybrid renewable energy system in Terengganu’. Instead of off-grid system considered in the conference version, inspired by feed-in-tariff introduced by The Government of Malaysia, this article includes grid-connected hybrid renewable energy system to examine their feasibility to be used as power supply for a household in Terengganu. In addition, this article compares the performance of grid-only system and hybrid grid-renewable energy systems in terms of cost of electricity and emission of pollutant. The payback period is also examined based on the current sellback rate. Sensitivity analysis is done to find the best sellback rate for a hybrid grid/PV/wind system to compete with a hybrid grid/PV system. In addition, the most optimal configuration is also determined by varying the value of solar radiation, wind speed and sellback rate. Generally, it is concluded that the hybrid grid/PV system is the most practicable choice to be used as power generator to supply electricity for a household in Terengganu

Microscopic study of Ca++Ca fusion

We investigate the fusion barriers for reactions involving Ca isotopes $\mathrm{^{40}Ca}+\mathrm{^{40}Ca}$, $\mathrm{^{40}Ca}+\mathrm{^{48}Ca}$, and $\mathrm{^{48}Ca}+\mathrm{^{48}Ca}$ using the microscopic time-dependent Hartree-Fock theory coupled with a density constraint. In this formalism the fusion barriers are directly obtained from TDHF dynamics. We also study the excitation of the pre-equilibrium GDR for the $\mathrm{^{40}Ca}+\mathrm{^{48}Ca}$ system and the associated $\gamma$-ray emission spectrum. Fusion cross-sections are calculated using the incoming-wave boundary condition approach. We examine the dependence of fusion barriers on collision energy as well as on the different parametrizations of the Skyrme interaction.Comment: 11 pages, 13 figure

Microscopic study of 16^{16}O+16^{16}O fusion

We perform a study of $^{16}$O+$^{16}$O fusion at above and below the interaction barrier energies using three-dimensional time-dependent Hartree-Fock (TDHF) calculations at above barrier energies and density-constrained TDHF calculations for the entire energy range. We discuss the variations of the experimental data at above the barrier energies. Calculations reasonably reproduce the observed energy-dependent broad oscillations in the fusion excitation functions. These oscillations result from overcoming $L$-dependent fusion barriers. The role of the coupling to low-lying octupole states is also discussed.Comment: 10 pages, 8 figure

Microscopic DC-TDHF study of heavy-ion potentials and fusion cross sections

We study heavy-ion fusion reactions at energies near the Coulomb barrier, in particular with neutron-rich radioactive ion beams. Dynamic microscopic calculations are carried out on a three-dimensional lattice using the Density-Constrained Time-Dependent Hartree-Fock (DC-TDHF) method. New results are presented for the $^{132}$Sn+$^{40}$Ca system which are compared to $^{132}$Sn+$^{48}$Ca studied earlier. Our theoretical fusion cross-sections agree surprisingly well with recent data measured at HRIBF. We also study the near- and sub-barrier fusion of $^{24,16}$O on $^{12}$C which is important to determine the composition and heating of the crust of accreting neutron stars.Comment: Talk given by .

Melacak Akar Radikalisme Islam di Indonesia

Radicalism nowadays becomes a popular discourse in Indonesia. The fall of Soeharto in 1998 was also followed by the rise of some groups which enroots their ideology and value with the ideology of Islamic political movement in Middle East. Many authors even connect this phenomenon to terrorism. By those points of view, they try to encounter terrorism by de-radicalizing people and promoting the empowerment of moderate society. But this point of view is argued by some authors who think that terrorism differs from radicalism. It is structural problem –poverty, oppression, political authoritarianism— which implies violence and terror. It leads us to a question: What cause radicalism? This article attempts to analyze the historical and political-economic root of Radical Islam group in Indonesia. By analyzing those problems, we will elaborate the problem of Islamic radicalism in structural perspective of post-New Order Indonesia

Improving the Students\u27 Reading Comprehension Through Know-want-learn Strategy

Improving The Students\u27 Reading Comprehension Through Know-Want-Learn Strategy at the first-grade students of SMA Negeri 18 Makassar. The objective of this research was intended to explain the improvement of the students\u27 interpretative and literal reading comprehension through Know-Want-Learn Strategy at the first-grade students of SMA Negeri 18 Makassar especially in class X 3. The strategy of this research was a Classroom Action Research (CAR) consisted of two cycles, one cycle consisted of four meetings. It means that there were eight meetings for two cycles. This classroom action research was done at the first-grade students of SMA Negeri 18 Makassar in Daya Regency for English subject. As the subject in this research was class X 3 in the 2012-2013 academic year with students\u27 number of about 32 students. Those consist of 22 women and 10 men. The instrument of this research was observation sheet and reading test or evaluation. The findings of the research were students achievement in reading comprehension was 54,07 in D-test, then Cycle I is 69,07 and it becomes 73,81 in Cycle II. The students\u27 activeness in learning reading comprehension in the first meeting of Cycle I was 45,39% then it becomes 90,78% in the fourth meeting of Cycle II

Pengaruh Murabahah Dan Struktur Modal Sendiri Terhadap Imbal Hasil Studi Pada Bpr Syariah Di Pulau Jawa

Rinto Noviantoro, Umar Purwoko; This research was aimed to determine the effect of growth and equity financing murabahah about returns in the form of return on assets in the Bank's Credit Rakyar Sharia (SRB) in the island of Java in the period quartalan ie Balance Sheet reporting period March 2011 s / d in December 2012 were published. The hypothesis testing using multiple linear test that examines the effect between murabaha and growth equity capital structure as an independent variable to variable yields as dipenden. Secondary Data collection method is by using quantitative analysis. Test statistics using Classical Test assumptions. The results of this study indicate that the murabahah and equity capital structure significantly influence yield, whereby the different results that the growth murabaha significant negative effect on BPR Syariah then capital structure itself significant positive effect on the yield on Syariah BP
