As a low cost and environmentally-benign powder technology, appropriate nanostructuring of fine particles (for example to produce porous, core-shell, hollow, or multicomponent composite structures) has attracted significant attention. Nanostructured fine particles have superior properties, such as high specific surface area, low density, hybrid functionalities, and resistance to weathering. Research into ways of nanostructuring particles for advanced functional materials has progressed rapidly, because these particles offer two great advantages over bulk materials or single component spherical particles: high performance and reduction in the use of expensive raw materials. In particular, the current interest in nanostructured particles focuses on tailoring their inner structure and morphology towards particular practical applications. This article reviews recent research progress on fabrication strategies for nanostructured fine particles. The examples chosen are phosphors, photocatalysts, electrocatalysts, adsorbents and magnetic particles. These fabrication techniques pave the way towards saving both resources and energy in materials production. © 2013 The Society of Powder Technology Japan. Published by Elsevier B.V.

Control of the shell structural properties [i.e., thickness (8-25 nm) and morphology (dense and raspberry)] and cavity diameter (100-350 nm) of hollow particles was investigated experimentally, and the results were qualitatively explained based on the available theory. We found that the selective deposition size and formation of the shell component on the surface of a core template played important roles in controlling the structure of the resulting shell. To achieve the selective deposition size and formation of the shell component, various process parameters (i.e., reaction temperature and charge, size, and composition of the core template and shell components) were tested. Magnesium fluoride (MgF2) and polystyrene spheres were used as models for shell and core components, respectively. MgF2 was selected because, to the best of our knowledge, the current reported approaches to date were limited to synthesis of MgF2 in film and particle forms only. Therefore, understanding how to control the formation of MgF2 with various structures (both the thickness and morphology) is a prospective for advanced lens synthesis and applications. © 2014 American Chemical Society.

Studies on preparation of porous material have attracted tremendous attention because existence of pores can provide material with excellent performances. However, current preparation reports described successful production of porous material with only partial information on charges, interactions, sizes, and compositions of the template and host materials. In this report, influences of self-assembly parameters (i.e., surface charge, size, and concentration of colloidal nanoparticles) on self-organized porous material fabrication were investigated. Silica nanoparticles (as a host material) and polystyrene (PS) spheres (as a template) were combined to produce self-assembly porous materials in film and particle forms. The experimental results showed that the porous structure and pore size were controllable and strongly depended on the self-assembly parameters. Materials containing highly ordered pores were effectively created only when process parameters fall within appropriate conditions (i.e., PS surface charge ≤ -30 mV; silica-to-PS size ratio ≤0.078; and silica-to-PS mass ratio of about 0.50). The investigation of the self-assembly parameter landscape was also completed using geometric considerations. Because optimization of these parameters provides significant information in regard to practical uses, results of this report could be relevant to other functional properties. © 2013 American Chemical Society.

This study aimed to develop school community to share knowledge by using Multimedia Learning Resource Sharing (MLRS). MLRS was developed as a means for educators and learners across schools to share online based internet. To measure MLRS’s acceptance as a medium of sharing knowledge, Technology Acceptance Model (TAM) was used as a model of approach. This study tried to explore factors that were dominant, interrelated and influential to the level of MLRS’s acceptance in sharing knowledge. Structural Equation Modeling (SEM) was used to analyze the data. The present study revealed that user Content Management (CM) affected Perceived Ease of Use (PEoU), while Content management (CM) and PEoU affected the benefits of Perceived Usefulness (PU). PEoU and PU affected Intention to Use (ITU); and ITU affected Actual System Usage (ASU). In general, the presence of MLRS received a positive acceptance from users in developing sharing knowledge between Senior High schools in West Java. © 2015 SERSC.

The Andreassen’s prediction model (1985) with the variables of population and vehicles to predict actual fatalities has been used in Indonesia. These variables need to be investigated and re-examined to suit the demographic characteristics of Indonesia with its vast area, large population, the largest number of vehicles among ASEAN countries, long road infrastructure, and poor driver discipline. This study aimed to determine which variables, out of the eight analyzed, namely population, vehicle, area, road length, driver behavior, licensed drivers, mobility, and accessibility, can be used to predict the number of actual fatalities in Indonesia. Employing a criterion-referenced test, linear correlation coefficient between variables, and correlation analysis of each variable with fatalities, the findings show: (1) The variables of ‘population’, ‘vehicle’, and ‘accessibility’ are the selected variables that have strong and significant effects on actual fatality number prediction; (2) The variable of licensed drivers has no positive effect on driver behavior; (3) The variable of poor driver behavior has a negative effect on actual fatality number prediction in Indonesia and to the other variables under research. Based on our research, we conclude that Andreassen model (1985) is not suitable for fatality prediction in Indonesia. It is recommended that road safety researchers in Indonesia develop fatality prediction models by considering the three selected variables in this study; thus, a new fatality prediction model which is in accordance with the characteristics of areas and road transport infrastructures in Indonesia can be obtained.

Currently, Indonesia is faced with the challenge of „modern human trafficking‟; a problem which continues to increase. Technology and social media are some of the tools which, on one hand, have been used to detect and understand the signs of this shameful behaviour, while on the other hand, facilitating this very act. In this study, the author aims to discover and understand the social challenges contributing to human trafficking, in terms of causes, recruitment patterns, victims‟ self-awareness, role of the family and society in awareness creation, and also the contribution of technology and social media in sensitising the public to the signs and factors promoting human trafficking. The findings of this study reveal that factors leading to human trafficking include both primary factors (such as poverty and lack of education) and secondary factors (which include lifestyle and the desire to be dutiful to parents). However, it was further established that these factors comprised an amalgamation of local, national, and global cultures which have been brought about as either direct human interaction or through information and communication technologies or the widespread social media, which have influenced victims‟ lifestyles and forced them to find an easier (instant) way to gain wealth. In conclusion, this study identifies learning methods that could be used across fields to promote understanding and a social inquiry on problems existing in society. © Research India Publications.

The image of Indonesian women on international level is partly influenced by the appearance of the First Lady. The role and position of the First Lady is the representation of Indonesian women, because basically the First Lady, as the wife who accompanies the President (head of state), has a strong background of cultural grip, high intellectuality and good personality in her daily lifestyle, including in wearing clothes, and as an ambassador of culture and design. Fashion style of the First Lady always draws praise and criticism from the public. The purpose of this study is to reveal the visualization effects of Indonesian First Ladies' kebaya clothing style in various state occasions on the image of Indonesian women's appearances. This study is a qualitative research of visual data that emphasizes the discussion of Kebaya Clothing using semiological study (connotation and denotation meaning) that bring out self-image. The results showed that the style the First Ladies' Kebaya clothing in every presidency period of their husbands had characteristics both in the style of clothing or hairstyle, indicating self-image. The conclusion of this study reveals that the First Ladies' Kebaya Clothing (National Clothing) is interpreted as having implied messages because clothing can be observed visually. Implication was done on the construction of learning patterns of clothing, national fashion design and Nusantara ethnic clothing design. © Published under licence by IOP Publishing Ltd.

Due to the use of electrical current load that uses a lot of electronic components (passive non-linear electrical loads), so the impact will cause harmonics in the electrical network system. These harmonics can unwittingly cause a relatively large loss in electrical energy consumption and can lower the power factor of an electrical installation. Limits how much the harmonic distortion that is installed on the load adjusted to the IEEE 519-1992 standard. The study was conducted by taking data on a network of electrical installation of a building using measuring devices Fluke 43B Power Quality Analyser. The data is then processed and consulted with the standard IEEE 519-1992. Once the data has a discrepancy with the standard, further made the filter design using linear passive components. The design is then installed on the network installation by means of simulated order harmonic losses can be overcome so that the circuit meets the IEEE standard installation by changing the parameters of the linear load L and C. The results of this study indicate that THDi value decreased after the installation of filters for phase R fell by 9.39%, the S phase decreased by 7.54% and for the T phase decreased by 16.88%. So that meets the IEEE standard by 15%. © Published under licence by IOP Publishing Ltd.
