Authors: Ohashi Takahiro , Wakiyama Kenta , Tabatabaei Hamed Mofidi , Nishihara Tadashi
Published: August 2020

In this paper, the authors propose a design for the mechanical joining of dissimilar materials by employing rivet-like structures fabricated by friction-stir forming (FSF) considering the stress concentration on the joined material. The authors have utilized the FSF approach to generate rivet-like joints as follows. First, a substrate material (an aluminum alloy plate) was placed on a joined dissimilar-material plate containing prepared holes, i.e., a steel plate. Afterwards, these materials were placed on a die containing the cavity to fabricate the head of the rivet-like structure. FSF was then conducted to form the stems and heads of the rivet-like structure from the substrate material. Unlike conventional riveting, fastener was not considered necessary for the process; therefore, choosing different diameters of the prepared holes with multiple joints for the optimization of their structural design was easier. It is known that two auxiliary holes neighboring a main hole on either side reduce the stress concentration on the rim of the main hole. In this study, the authors applied the “round-hole-array design” on rivet-like joints fabricated by FSF. The authors examined the design of two smaller prepared holes with a commercial Finite element analysis (FEA) software for the rivet-like joint containing a 4 mm-diameter hole on a joined plate. To prove this, a 3 mm-thick A5083P-O aluminum alloy plate and a 0.7 mm-thick and 20 mm-wide SPCE steel plate was joined with the suggested design, and the strength and fracture of the joints were investigated using the tensile shear test. As a result, all joints were destroyed by the facture of the prepared holes, and it was confirmed that their strength was improved by the round-hole-array design.

Published: August 2020

The energy absorbing performance in the progressive failure of glass long-fiber-reinforced polyamide was evaluated by using the split Hopkinson pressure-bar method. An impact compression test of glass long-fiber-reinforced polyamide was performed from –30 °C to 90 °C, and the temperature-independent energy absorbing performance was confirmed only for the progressive failure mode. To clarify this phenomenon, compression tests, interlaminar compressive shear tests and mode-I fracture-toughness tests were conducted under static and impact conditions. The compression strength and the shear strength of all specimens decreased with an increase in temperature. The toughness improved with temperature. In addition to the mechanical tests, failure-mode analysis was performed by using a three-dimensional X-ray microscope to clarify the absorbing mechanism. From the above, it was concluded that the temperature-independent energy absorbing performance results from a balance of these mechanical properties against the temperature change.

Published: August 2020

The fatigue strengths in notched specimens of carbon-carbon composites were investigated. Slits of different length were cut on both sides of a test section to investigate the impact of notch sensitivity on fatigue life. Specimens with blunt-notches on the both side of the specimen, and center hole were also used to compare the critical stress, sw. The fatigue limit was measured using S-N curves. From the experimental result, it was found that specimens with blunt-notches have lowest fatigue limit. The relationships between critical stress, sw and specimen geometry were investigated by stress concentration factor, Kt and stress intensity factor, KI which was done two dimensional body forced methods. Consequently, it was discussed that the damage condition in the vicinity of the notch or slit, and the crack initiation behavior affects the fatigue strength. Also, the S-N curve and fatigue limit was related to the crack growth in shear mode.

Air permeability is one of the thermal comfort properties of clothing and fabrics. This study evaluated the air permeability properties of summer cooling towels of different brands available in the market, “Perfect Fitness”, “N-rit” and “Cooldyxm” and an anonymous ice towel. The air permeability function of the cooling towels was evaluated instrumentally. Other than the air permeability property, other fabric specification such as fiber composition, fabric type, fabric weight, fabric thickness, yarn linearity and fabric density were measured. Some specifications were found to have good statistical correlation with the air permeability. Based on the experimental results and statistical analysis, the sample of Perfect Fitness was found to have the poorest cooling effect, whereas N-rit, Cooldyxm and Ice Towel samples had comparable air permeability properties. The best performance of air permeability was seen in N-rit sample. The underlying reason could be ascribed to the fabric structure and thickness. This study can provide some information for choosing cooling towel for practical use.

Published: August 2020

In this work, aluminum-doped ZnO (AZO) is synthesized for heat-shielding applications. A family of ethanolamine (EA: monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine TEA)) is used to control the morphology of aluminum-doped ZnO (AZO) synthesized via a simple solvothermal method at the temperature of 120°C for 6 h. The samples were characterized by field-emission scanning electron microscopy (FE-SEM). The formation of primary ZnO nanoparticles (NPs) showed that TEA yielded highly packed-spherical aggregates not found when DEA and MEA were used. X-ray diffraction (XRD) found that all AZO samples have peaks of the ZnO hexagonal wurtzite structure. XRD patterns of aluminum were found for >10 mol%. UV-Vis-NIR spectrophotometer was used to study the optical property and heat-shielding of the near-infrared region (NIR, the wavelength from 700 - 2500 nm). All AZO NPs of 0, 2, 4, and 10 mol% exhibited strong NIR shielding ability up to 80% insulation. From these results, the AZO NPs have potential use as NIR shielding materials of low-cost and simple processes to be coated on an energy-efficient window as smart window coating in buildings and automotive thus reducing energy consumption, especially in air conditioning usage.

Published: August 2020

Membrane technology has attracted significant attention from the researchers, especially in gas separation process due to their simple process design and low capital cost compared to conventional techniques. In this work, oil palm frond (OPF) waste was used as nanoadsorbent embodied in polyether block amide (Pebax 1657) nanocomposite membrane to improve the CO2/CH4 separation. The effectiveness of the nanoadsorbent derived from OPF was evaluated by varying the nanoadsorbent concentration (2–8 wt %) and controlling the Pebax 1657 concentration (5 wt %), dipping time (5 s), and number of sequential coatings (3 layers). The pore characteristics of the nanoadsorbent was analyzed using Brunauer–Emmett–Teller (BET) analysis. The morphology and the existence of active groups in the newly synthesized nanoadsorbent and nanocomposite membranes were investigated using field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR), respectively. The single gas permeation process was carried out at constant pressure (2 bar) and room temperature (25 ± 5 °C). The optimum condition with 5 wt % nanoadsorbent made the nanocomposite membrane exceeded the trade-off limit of the Robeson plot with a CO2 permeability and CO2/CH4 selectivity of 1475.09 Barrer and 40.48, respectively.

Published: August 2020

Conventional cement production process emits tons of carbon dioxide gas which is one of the greenhouse gases that influence the environment across the world. Discovering the alternative construction material with the eco-friendly process and the performance similar to or greater than ordinary Portland cement has been attractive to find out. This research presented green construction materials or so-called geopolymers from metakaolin substituted by high calcium fly ash by 20, 40, 60, 80 and 100 wt%. Some researches reported that geopolymer produced from metakaolin and fly ash with alkali solution gave a great result, but usually, they used fly ash containing very low calcium component. Compressive strength at 3, 7 and 28 curing days and flowability were conducted. The compressive strength of geopolymers blended with high calcium fly ash was still developed as the curing day increased and revealed the highest at 28 days especially on MK40 (high calcium fly ash 60 wt%). Geopolymer pastes prepared with a higher amount of high calcium fly ash exhibited less viscous. It was proved that the high amount of high calcium fly ash could be applied and gave extraordinary compressive strength. Furthermore, X-ray diffraction and X-ray fluorescence were used to investigate chemical properties as well as microstructure by a scanning electron microscope. For phase analysis, the existence of oxides of calcium and sulfur in high calcium fly ash resulted in the formation of thenardite, calcite, portlandite and C-S-H phase associating with geopolymeric phase. Therefore, this research proposed the opportunity for geopolymer production by using abundant high calcium fly ash to raise the value of the industrial waste products and green alternative construction material compared with OPC.

Published: August 2020

The influence of volumetric hydrophobization of cement stone samples on mass transfer processes during hardening has been studied. It was found that the introduction of a hydrophobizing additive at the stage of sample production reduces the amount of water evaporating during drying. With increasing concentration of the hydrophobizer mass transfer processes are slowed down during the hardening of cement concretes, which affects their structural and phase composition, strength characteristics and durability.

Published: August 2020

The Simple Performance Test (SPT) can be used to characterize the strength and load resistance of asphalt mixtures. The objectives of this study are to determine the effect of temperature on the phase angle and dynamic complex modulus of the asphalt mixtures tested at 30°C, 35°C, 40°C, 45°C and 50°C at 25Hz, 20Hz, 10Hz, 5Hz, 1Hz and 0.5Hz frequencies. The asphalt mixtures of NMAS 12.5mm are prepared using asphalt binder PEN 80/100 and PEN 60/70. The asphalt mixtures are designed using the Superpave system and compacted using the Superpave Gyratory Compactor (SGC). The dynamic modulus test results showed that at a higher temperature, the stiffness of the asphalt mixtures is affected. The dynamic modulus of the mixtures is highest at 30°C and gradually decrease at 35°C, 40°C, 45°C and 50°C respectively. The dynamic modulus values for asphalt mixtures with bitumen grade PEN 60/70 are also higher compared to the asphalt mixtures with bitumen grade PEN 80/100. Results also showed that the low phase angle values indicate low viscosity of the asphalt binder due to increase in temperature. The present study is meaningful in understanding the asphalt mixture behaviour at different temperature and loading frequencies.

Published: August 2020

Formally, inclusive education is part of the primary policies in the Greek educational system. However, pupils with intellectual disabilities still attend special schools and their socialization is mainly monitored through the implementation of social co-existence programs in the school setting. The present study aimed to explore the outcomes of a social co-existence program that was implemented in two co-located schools, a general education elementary school and a special education elementary school. Semi-structured interviews with the special education elementary school pupils were used for pre- and post-intervention assessments. Qualitative analyses of the data revealed important differentiations in the ways pupils with intellectual disabilities understood a) their social interaction with typically developing peers and b) acceptance by peers. In fact, the pupils with intellectual disabilities consistently acknowledged that participation in the social co-existence program enhanced their social interactions and improved acceptance by peer.

PERSPEKTIF TEOLOGIS TERHADAP ETIKA BISNIS KRISTEN
Authors: Bambangan Malik
Published: August 2020

Abstract: The perspective of the Christian faith in understanding the world of work is the same when it is involved in the work. In the business world, according to some opinions it is solely for profit. In the perspective of the Christian faith, business is a manifestation of one's faith responsibilities towards God and others. The perspective of the Christian faith in the business world must be understood as a service. Therefore, ethical business ethics in the perspective of Christian faith need to be understood and implemented based on the Word of God.

Abstrak: Sudut pandang iman Kristen dalam memahami dunia kerja adalah sama ketika terlibat di dalam pekerjaan tersebut. Dalam dunia bisnis menurut beberapa pendapat adalah semata-mata bertujuan mencari untung. Dalam perspektif iman Kristen melihat bisnis sebagai perwujudan tanggungjawab iman seseorang terhadap Tuhan dan sesama. Perspektif iman Kristen terhadap dunia bisnis mesti dipahami sebagai suatu pelayanan. Oleh sebab itu etika berbinsnis dalam perpektif iman Kristen perlu dipahami dan dijalankan dengan berdasar pada Firman Tuhan.

Published: August 2020

The aim of this study is to determine whether the “Day-of-The-Week Anomaly” (DOWA) exists on different stock capitalization in Indonesian stock market. A total of 58 stocks listed in both LQ45 index and Pefindo25 index used to represent large cap stocks and small and medium cap stocks respectively. The Ordinary Least Squares (OLS) method and ARCH/GARCH model were employed to capture the DOWA and the daily volatility behavior for the period between January 2010 and December 2015. The result reveals that DOWA exist for a significant proportion of individual stocks in both LQ45 and Pefindo25. Monday was found to have the lowest mean returns while Wednesday has the highest mean return. The differences between Monday’s return and return of the other days ranged from 0.15 to 0.41 percent. LQ45 stocks also found to have slightly higher Wednesday’s volatility than of Pefindo25 stocks. It indicates that the higher return of the LQ45 is naturally accompanied by a higher risk.

Based on the result of the survey, it is unravelled that there are 18 percent of cars which have non-BE plate number operating in Lampung, and for motorcycles, there are only 4 percent. Another finding shows the fact that respondents buy vehicles outside the province of Lampung  because the price difference is quite significant and they do not do second BNKB in Lampung Province in accordance with its operational area. From the willingnes to pay, all respondents approve that if the rate of BBNKB decreases back to 10 percent,  most of them will return to buy a new vehicle in Lampung due to the fact that there will be smaller price difference between the price of a new car purchased in Lampung Province and new car purchased outside Lampung Province. BBNKB tariff reduction will provide opportunities for trade of vehicles in Lampung Province to be more competitive, thus, they can develop better. Moreover, there will be more exciting investments and more job fields in the automotive sector.

IMPACTS OF IMPORT TARIFFS AND NONTARIFF MEASURES ON INDONESIA’S TRADE PERFORMANCES OF ENVIRONMENTAL GOODS: A GRAVITY MODEL
Authors: Mahendra Made Satriawan , Solikin Akhmad
Published: August 2020

In 2011 leaders of Asia-Pacific Economic Cooperation (APEC) members pledged to reduce tariffs and nontariff barriers on goods and services related to environmental goods, known as APEC Environmental Goods List. In 2012 it was agreed that the member countries will reduce import tariff for the environmental goods to be maximum of 5% by 2015. The commitment is controversial since it is agreed as APEC commitment and hence nonbinding. However, since the tariffs are applied under Most Favored Nation principle, by definition the tariffs apply to all countries. This article aims at analyzing impacts of import tariffs and nontariff barriers for the environmental goods on Indonesia’s trade performances. In this study, the environmental goods include APEC Environmental Goods List and WTO Environmental Goods Core. The gravity model is used to explain variations in Indonesia’s exports and imports of 54 environmental goods to 18 trading partners. Data included in the analysis were obtained from secondary sources and were analyzed using fixed effect panel data regression. The results show that import tariffs do not affect import, while they affect export negatively. The nontariff measures affect positively to both import and export performances. Other variables, namely the gross domestic product and distance are significant and have influence as predicted by theory.

THE IMPACT OF CHINA SHOCK ON DEINDUSTRIALISATION OVER TIME
Authors: Utami Nugraheni Dwi
Published: August 2020

This paper analyses the impact of Chinese import competition on deindustrialization measured by real value added and employment share in 61 developed and developing countries over 1970-2010 period. By employing quantile regression with instrumental variables to correct potential endogeneity bias, the results suggest that the main driver of deindustrialization in employment in developed countries is technological change. There is heterogeneous effect of China shock. In developed countries, the effect is destructive in term of both employment and real value added in the lower quantile of distribution, with the higher magnitude for the former. In the higher quantile, complementary effect outweighs detrimental impact. In developing countries, the negative effect of China’s shock on real value-added rises as the increase in the proportion of manufacturing value-added in countries. The destructive effect on employment in developing countries seems to be harder after 1990 period.

The Effect of US Monetary Policy Normalization Toward The Financing Growth of Indonesian Islamic Banking Industry: Short-Term and Long-Term Approaches
Authors: Mikail Ahmad , Indraswari Kenny Devita
Published: August 2020

The study identifies the effect of The Fed Fund Rate (FFR) normalization toward the financing growth of Islamic banks as well as toward the industrial credit growth in Indonesia. To acquire better understanding about the effect of the increasing FFR, Vector Error Correction Model is being utilized in order to identify short run and long run effects. The data employed are the quarterly data of total credit in banking industry, total financing in Islamic banking industry, FFR, real GDP growth, real interest rate, exchange rate and Indonesian composite index from 2003 - 2015. To forecast the dynamic effect of the rising FFR towards financing growth in the Islamic banks, Impulse Response Function is being applied. The result from the long run estimation suggests that the Fed’s monetary policy has negative effect toward the Indonesian banking credit growth as well as the Islamic financing growth. Moreover, the estimated coefficient shows that the effect is quite low in the long run for the conventional bank and relatively high for the Islamic banks. From the short run dynamic analysis, the study reveals that the Islamic banks financing growth is mostly determined by FFR where Islamic financing growth affects Indonesian composite index and real interest rate. However, the Impulse Response Function result exhibits that the Fed’s monetary policy normalization will not affect Islamic banks financing in Indonesia.

Management of Zakah Distribution: Empirical Evidence From Indonesia
Authors: Kasri Rahmatina A.
Published: August 2020

Despite the importance of zakah distribution, few studies attempt to evaluate practices in managing the distribution. The paper, thus, aims to explore approaches and evaluate practices in managing the zakah distribution. It employs qualitative research approach with semi-structured interviews with key management personnel of seven largest zakah organizations in Indonesia. The main finding identifies two approaches in distributing zakah in Indonesia, namely consumptive disbursement and productive utilization approaches. Each approaches is different in terms of purpose/expected impact, types/nature of programs and methods of distributing the zakah proceeds. It is also found that different types of zakah organizations tend to focus on different zakah distribution approach. Moreover, some challenges are identified particularly in relation to selection/coverage of mustahik and threat or ‘competition’ in distributing zakah funds. Overall, the study highlights the increasing relevance of productive utilization approach as well as importance of enhancing outreach and availability of information related to zakah programs (including through online platforms) and continuously educate all zakah stakeholders. The findings are expected to provide insights in managing zakah distribution in Indonesia and ultimately in increasing effectiveness of zakah institution to achieve its objectives.
