Abstract
Supply chain management has become a crucial aspect of the performance of industries and companies as it manages the flow of goods, services, and information in order to fulfil customers need while reducing the total costs. In order to reduce the production total cost, e-procurement is introduced. E-procurement means of reducing cost is by shortening cycle time and create a simpler procurement process. The aim of this research is to develop a vendor management and e-procurement system using the Android platform. The developed system is hoped to be able to even shorten the cycle time, ease vendor selection and provide a more flexible and convenience procurement process. Through data measurement and documentation review, the developed system was tested against these three parameters for their validity. In the end, this research summarizes the test result and conclude based on the test result that those parameters are achieved in the developed vendor management and e-procurement system.

Published: June 2019

Abstract
Electric market deregulation aims to provide flexibility for customers to have many suppliers and low prices. However, market deregulation also provides opportunity for certain parties to manipulate supply, so there is a scarcity of products that result in price increases. Therefore, this research proposes a collaborative strategy for electricity market deregulation using the Multi Echelon distribution model applied in East Kalimantan with dummy data. Collaboration strategy made based on optimization of mathematical models in two stages and three scenarios. The simulation was carried out using Excel Solver covering three regions, dynamic time and estimated price fluctuations over three periods. As a result, Gencos gets the biggest profit when serving basic load. Whereas wheeling occurs, the D4 region is a strategic area that generates the largest profit compared to the D1 and D6 regions.

Abstract
Good risk management will reduce the impact and risk of an event. In this study discussed the risks that may arise in the wooden toy industry supply chain and how to manage these risks. The calculation divided into three phases; there are risk mapping, risk assessment, and risk management. House of Risk (HOR) is used in calculating potential risks and Analytical Network Process (ANP) is used to choose the best strategy for supply chain risk management. Followed by HOR calculation, risk that has the greatest value and selected as potential risk is the risk of price/cost fluctuations with an ARP value of 432. The strategy of this risk is grouped based on 2 causes, namely raw material price fluctuations and poor management. With ANP calculations, the strategy for raw material price fluctuations are understanding and determining the quantity of material used (28.14%) and combining woods with various commodities (23.23%). Then the alternative for poor management are doing strategic financial accounting (54.48%) and doing financial planning (33.07%).

Published: June 2019

AbstractArticle 33 of the1945 Constitution clearly states that all vital factors of production, called strategic industries, are controlled by the state and to be use for the prosperity of Indonesian people. This article implies that the strategic industries supply chain should be managed accordingly. The fourth amendment of the 1945 Constitution offers a macro framework as principles to conduct the supply chain. They are Togetherness, Efficiency of justice, Continuity, Environmental perspective and Self-Sufficiency. Furthermore, the framework can be used to build performance measurement indicators for the supply chain. Currently the method that is widely used to measure supply chain performance is the Supply Chain Operation Reference (SCOR). This study studied the relations of the strategic industries principle and performance indicators within the SCOR. Twelve professionals and researchers are interviewed as respondents to investigate those relations. More than 90% respondents agreed that; (1) the principle of togetherness is strongly related to Reliability, Responsiveness and Agility; (2) Efficiency of justice is strongly related to Responsiveness; (3) Continuity is strongly related to Agility; (4) Environmental Perspective is strongly related to Green Supply Chain, and; (5) Self-Sufficiency is strongly related to Responsiveness. Therefore, SCOR performance measurement attribute is related with the strategic industries principles.
Effect of Water and Acid Pre-treatment on the Physicochemical Properties of Rice Husk for Silica Extraction
Authors: Librea J T , Dacanay F D , Martin Z Z , Diaz L L 
Published: June 2019

Abstract
Rice husks are residue materials from rice milling. These materials are mostly discarded after obtaining the rice, however, numerous studies have found out that rice husks are an excellent renewable source of silica. Rice husks are generally turned into rice husk ash in order to extract the silica in the material. Prior to the combustion process, pre-treatment methods are usually done in order to minimize the impurities in the husks. Failure to remove these impurities lead to undesired properties of the extracted silica. As such, we investigate some common pre-treatment methods, namely water and acid (HCl) treatment, and their effects on the surface morphology and elemental composition of the husks after treatment. It was found that H2O was more effective in removing the bromide ions Br−, while HCl becomes less effective at increasing concentration. Also, acid treatment was more effective in removing the sodium and potassium components compared to water treatment. However, efficiency decreases as the acid concentration increases due to interference of silica polymerization. Thus, for the removal of impurities in rice husk, lower concentration of acid pre-treatment is recommended.

Published: June 2019

Abstract
All The metal composite was prepared in this research by utilizing waste of aluminum and gray cast iron chips in supporting the global program of sustainable recycling-oriented society. The process was carried out via hot extrusion at 400°C. Three compositions were provided in this research, namely the composition of aluminum chips with addition 0 vol.%, 20 vol.%, and 40 vol.% of gray cast iron chips. Increasing the gray cast iron was found affect on reducing the natural frequency of the product. Addition about 20 vol.% of gray cast iron decreases the value of damping capacity. Conversely, addition about 40 vol.% gray cast iron increases the value of damping capacity significantly. It was also found that the addition of gray cast iron could extend the isolation region and decreased the transmissibility at the isolation region.

Authors: Nguyen P T N , Abbès F , Abbès B , Lecomte J-S , Schuman C 
Published: June 2019

Abstract
In this study, the orientation-dependent response of as-received annealed cold-rolled pure zinc and material with thickness reduction rate of 50% grains using instrumented indentation tests is investigated. The experiments were characterized by orientation microscopy and atomic force microscopy scans to quantify the orientation-dependent mechanical response during nanoindentation. The single crystal hardening parameters are then identified for each family of slip system by using crystal plasticity finite element (CPFE) simulations. Comparison between experimental and numerical results in terms of “load-penetration depth” curves show a good agreement. The increased percentage of cold reduction increases the identified critical resolved shear stress (CRSS). Finally, the accuracy of the model is evaluated by comparing experimental and numerical data issued from nanoindentation response grains of distinct crystalline orientations involving different slip systems activity rates.

Published: June 2019

Abstract
Flexible-bending, as a new bending technology, is widely used in the processing of profiles and tubes, especially in the production of small batches and multi-curvature. In flexible-bending process of tubes, the stress is complex and the springback problem exists which affects the forming accuracy and quality of bent tubes. In this paper, the springback is studied and solved by springback compensation by means of finite element numerical simulation and experimental verification. The results show that the wall thickness of tubes and the bending radii have important influence on springback. Springback compensation can effectively solve the problem of forming error caused by springback because that the forming radii after compensation can approach the target radius gradually. The experiments were carried out with flexible-bending equipment. The simulation results were in agreement with the experiments, which proved the reliability of the simulation.
Characterisation of fac-tris [2-phenylpyridinato-C2, N]iridium(III) by inelastic neutron scattering spectroscopy and periodic density functional theory
Authors: Parker Stewart F 
Published: June 2019

Abstract

fac-Tris[2-phenylpyridinato-C
2, N]iridium(III) (tris-(2-phenylpyridine) iridium, [Ir(ppy)3]), is a metal complex with applications that range from its use in organic light emitting diodes, to its acting as an efficient photocatalyst for a variety of organic reactions. In this paper the INS spectrum of this material is recorded for the first time and it is analysed by periodic density functional theory calculations of both its trigonal and tetragonal polymorphs. The differences between the calculated INS spectra of the trigonal and tetragonal forms and the isolated molecule demonstrate that the intermolecular interactions play a significant role. This is surprising for what is, nominally, a van der Waals solid.
Transmission of entangled photons studied by quantum tomography: do we need plasmonic resonances?
Authors: Remy Mathilde , Bokic Bojana , Cormann Mirko , Kubo Wakana , Caudano Yves , Kolaric Branko 
Published: June 2019

Abstract
We performed quantum tomography to reveal the robustness of quantum correlations of photons entangled in polarisation after their interaction with plasmonic and nonplasmonic environments at normal incidence. The experimental findings clearly show that the visibility of quantum correlations survives the interaction, and that the presence of plasmonic resonances has not any significant influence on the survival of polarisation correlations for transmitted photon pairs. The results indicate that quantum states can be encoded into the multiple motions of a many-body electronic system without demolishing their quantum nature. The plasmonic structures and their resonances only enhance the overall transmission. Thus, they could benefit the pair detection rate, that is the number of coincidences per unit of time, but they do not affect the visibility of quantum correlations. We also performed quantum tomography of the entangled pairs after interaction with the continuous planar gold film as a function of the incidence angle. The latter illustrates the loss of polarization correlations that arises from the partially polarizing properties of the isotropic sample out of normal incidence. Our work shows that plasmonic structures are not needed to exploit quantum entanglement if the rate of coincidence counting is sufficient.
A robust algorithm for k-point grid generation and symmetry reduction
Authors: Hart Gus L W , Jorgensen Jeremy J , Morgan Wiley S , Forcade Rodney W 
Published: June 2019

Abstract
We develop an algorithm for i) computing generalized regular

k

-point grids, ii) reducing the grids to their symmetrically distinct points, and iii) mapping the reduced grid points into the Brillouin zone. The algorithm exploits the connection between integer matrices and finite groups to achieve a computational complexity that is linear with the number of

k

-points. The favorable scaling means that, at a given

k

-point density, all possible commensurate grids can be generated (as suggested by Moreno and Soler) and quickly reduced to identify the grid with the fewest symmetrically unique

k

-points. These optimal grids provide significant speed-up compared to Monkhorst–Pack

k

-point grids; they have better symmetry reduction resulting in fewer irreducible

k

-points at a given grid density. The integer nature of this new reduction algorithm also simplifies issues with finite precision in current implementations. The algorithm is available as open source software.

Published: June 2019

AbstractMotivationMeiotic recombination facilitates the transmission of exchanged genetic material between homologous chromosomes and plays a crucial role in increasing the genetic variations in eukaryotic organisms. In humans, thousands of crossover events have been identified by genotyping related family members. However, most of these crossover regions span tens to hundreds of kb, which is not sufficient resolution to accurately identify the crossover breakpoints in a typical trio family.ResultsWe have developed MRLR, a software using 10X linked reads to identify crossover events at a high resolution. By reconstructing the gamete genome, MRLR only requires a trio family dataset and can efficiently discover the crossover events. Using MRLR, we revealed a fine-scale pattern of crossover regions in six human families. From the two closest heterozygous alleles around the crossovers, we determined that MRLR achieved a median resolution 4.5 kb. This method can delineate a genome-wide landscape of crossover events at a precise scale, which is important for both functional and genomic features analysis of meiotic recombination.Availability and implementationMRLR is freely available at https://github.com/ChongLab/MRLR, implemented in Perl.Supplementary informationSupplementary data are available at Bioinformatics online.
