Abstract

GPS data of Sinabung Volcano during year 2012 to 2013 has been processed using Gamit 10.5 then we correct the data from global and local noise to get surface paramaters of Sinabung Volcano. After we get surface parameter we applied Mc Tique model with very fast simulated annealing (VFSA) Inversion Scheme. From the inversioan we concluded that the position of magma chamber divide in 3 period, on 1st period the magma chamber is on ± 27 km, on 2nd period is on ± 16 km and the 3th period is on ± 0.5km below Sinabung Valcono. That result showed that the magma migrated from the deep into shallow part and indicated that Sinabung Volcano is on active status. Keywords: Pressure source, VFSA, McTique Model, Sinabung.

Abstract

For the design of fast nuclear reactors, usually it use the lead metal alloys for coolant materials. Researches about lead coolants, has been carried out experimentally. However, experimental studies in the nuclear material field, besides being expensive, usually also require high safety. In particular, research on the corrosive properties of liquid lead for structural materials requires serious treatment if carried out experimentally. In this case, the computational method is very helpful to overcome these obstacles. In our research we use the molecular dynamics simulation method to know the effect of temperatures and effect of liquid lead corrosion attack to iron material. We want to know that which one is most crucial that causing the damage of the materials: it is due to temperature or due to liquid lead attack. It has been observed from MSD curves of simulation results that the liquid lead can make iron material experiencing most damage if compared with temperature effect The interactions among atoms are described by the Lennard-Jonnes interaction potential. The simulations was run and supported using Moldy and Ovito software.Keywords: Corrosion of molten lead, fast nuclear reactor, molecular dynamics simulation, Moldy, MSD, Ovito.

Abstract

Keeping in mind our community's dependency on non-renewable sources of energy, it is a gravitating issue that seeks our attention and requires us to switch to renewable sources of energy at the earliest. A Dye-Sensitized Solar Cell (DSSC) is a third-generation photovoltaic technology that has immense capability to become highly commercial in a few years. Along the same lines, it is necessary to highlight that current DSSCs have shallow lifetime values, stability and performance. The efficiency of current DSSCs and the need to tackle their choice of materials and long-term stability is a concern. Some of the highest recorded efficiency values are around 12%, and this calls for severe replacement of conventional DSSC materials, modifications in the device structure and molecules, and improvement in testing and scaling-up measures. This review article underlines an introduction to DSSCs, working principle, components, high-efficiency DSSCs, strategies to improve device performance, DSSCs research in India, the advantages and disadvantages of the device, and recent research on fruit and flower-based DSSCs. Keywords: Dye-Sensitized Solar Cells, Solar Cell Materials, Third Generation Photovoltaics, High-Efficiency Dye-Sensitized Solar Cells, Solar Cells.

Abstract

Energy is one of the most important elements for every Government in the world, and we have seen struggles for energy between some countries or governments and their people. Energy is a strategic element for countries especially industrial countries, and Oil has been one of the oldest and most important source of energy in the world, since the 19th century, after coal and other kinds of energy. We want to investigate status of Oil as an old energy resource and renewable energy and what will happen in the future for users and producers of it.

Abstract

Analyzing the structure of the material in the fields of material science needs a very good device and methods. Due to its principle in projected images at various tilt angles and calculation of the three-dimensional volume reconstruction with a distinct algorithm, tomography become an excellent tool for analyzing the 3D structure. Several research has been studied to apply electron tomography in ESEM (Environmental Scanning Electron Microscopy) which gives an opportunity in observing the wet material (hydrated) in the aquatic environment. In this research, we showed the advisability of wet-Carbon compound tomography by simulating the interaction of electron materials. Monte Carlo simulation was applied in this study to calculate the optimum water layer thickness in the wet material detected.Keywords: Carbon, Electron Tomography, Simulation of Monte Carlo, STEM

Abstract

The liquid lead corrosion is often described as a damage of the metal surface due to the high solubility of atoms of the metal that flowing into the liquid metal medium through the diffusion process. This research was conducted to examine the performance of FeNi alloys in liquid lead at various compositions, especially the metal structure conditions due to interactions between metal atoms at high temperatures. To see the performance of this FeNi alloy steel, the parameter that you want to know is the diffusion coefficient of its constituent elements. The potential used is the Lennard-Jones potential. This research uses the LAMMPS molecular dynamics simulation software. From the simulation works can be concluded that the lowest diffusion coefficient of Fe in liquid lead which produces the strongest structure is at the composition (concentration) 65% Fe and 35% Ni with related diffusion coefficient of 5.8582 x 10-12 m2/s, where at this value the corrosion of FeNi in Liquid lead can already be reduced till 77.32%.Keywords: Liquid lead corrosion, Molecular dynamics, FeNi Alloy, Composition, LAMMPS.

Abstract

The effective use of waste biomass is an important factor for sustainability and global energy consciousness. Unsurprisingly, tree wastes such as leaves, petiole and branch are plentiful during trimming or autumn season which offer an economical source of biomass. The objective of this study was to probe the mechanical and thermal characteristics of briquettes created from tree waste of langsat, guava and rambutan tree. Collected tree wastes (leaves, petiole and branches) were chopped, mixed and then carbonized at 400-600 °C using a Charcoal Retort tube system. The briquettes were molded manually using a Hydraulically Briquetting Machine at pressures of 20 and 50 N/cm2 for half an hour to 3 hours with regards on the type, density and fragments of the tree. Two system and machine were designed and fabricated by Biophysics Lab, Dept. of Physics, Faculty of Mathematics and Natural Sciences, Universitas Jember. Results indicated that briquettes made from tree waste of langsat, guava and rambutan have signs of mechanical and thermal properties which can be used as briquettes for various industrial uses.Keywords: Sustainability, Alternate fuel, Tree waste, Biomass, Briquette

Abstract

Analysis of the neutron mean free path in the slab reactor core has been carried out using one-dimensional multi-group diffusion equation. This study aims to determine the neutron mean free path in the slab reactor core with the neutron diffusion coefficient calculation using macroscopic cross-section data in the nuclear fuel cell level and the neutron flux distribution. The type of reactor used in this research is a fast reactor with nuclear fuel is uranium-plutonium nitride (U-PuN). The neutron mean free path is calculated for 70 energy groups of neutron by dividing the energy groups, namely the fast energy group, the intermediate energy group and the thermal energy group. The results showed that the neutron mean free path value for U-235 and Pu-239 fuels were obtained almost the same in all energy groups, namely in the fast energy group ranging from 0.11.10-2 to 0.17.10-2 cm, in the intermediate energy group 0.16.10-2 to 1.78.10-2 cm, and in the thermal energy group 0.4.0-2 to 8.04.10-2 cm. The neutron mean free path value for U-238 fuel is much smaller than that for U-235 and Pu-239 fuel, ranging from 0.03.10-2 to 0.36.10-2 cm. These results can be confirmed, because U-238 fuel is a fertile material. Keywords: Neutron mean free path, diffusion equation, neutron flux, slab reactor core
