Abstract

Purpose

The purpose of this paper is to reformulate the governing equations incorporating major variables and parameters for the design a Micro Air Vehicle (MAV), to meet the desired mission and design requirements.

Design/methodology/approach

Mathematical models for various spherical and cylindrical Coandă MAV configurations were rederived from first principles, and the performance measures were defined. To verify the theoretical prediction to a certain extent, a computational fluid dynamic (CFD) simulation for a Coandă MAV generic models was performed.

Findings

The major variables and parameters of Coandă MAV have been formulated into practical guidelines, which relate the lift (or thrust) produced for certain input variables, particularly the Coandă MAV jet momentum coefficient. The influences of the geometrical parameters are elaborated.

Research limitations/implications

The present analysis on Coandă jet-configured MAV is focused on the lift generation due to the Coandă jet effect through a meticulous analysis. The effects of viscosity, the Coandă jet thickness, the radius of curvature of the surface and the stability of Coandă jet are not considered and will be the subject of the following work.

Practical implications

The results obtained can be used for sizing in the preliminary design of Coandă MAVs.

Originality/value

Physical and mathematical models were developed which can describe the physical phenomena of the flow field near the Coandă MAV surfaces influenced by Coandă jet sheets and for obtaining a relationship between relevant variables and parameters to the lift of practical interest.

Abstract

Purpose

This paper aims to discuss the physical and thermal properties of the three-dimensional (3D) printing natural composite filament, as well as the tensile behaviour of the printed composites to get an insight of its possibility to be used as an ankle–foot orthosis (AFO) material.

Design/methodology/approach

Physical test that was conducted includes scanning electron microscopy analysis, thermogravimetric/differential scanning calorimetry analysis as well as the effect of fibre load after extrusion on the filament morphology. Tensile test was conducted with different amounts of fibre loads (0, 3, 5 and 7 Wt.%) on the printed specimens.

Findings

There is an increment of strength as the fibre load is increased to 3 Wt.%; however, it decreases significantly as it is increased to 5 and 7 Wt.% because of the presence of voids. It also shows that the extrusion temperature severely affects the structure of the filaments, which will then affect the strength of the printed composites. Based on the results, it is possible to use kenaf/polylactic acid (PLA) filament to print out AFO as long as the filament production and printing process are being controlled properly.

Originality/value

The unique aspect of this paper is the investigation of kenaf/PLA filament as a material for 3D printing, as well as its material consideration for AFO manufacturing. This paper also studies the effect of extrusion temperature on the morphological structure of the filament and its effect on the tensile properties of the printed kenaf/PLA specimen.

Abstract

Purpose

The purpose of this study is to integrate and synthesize the Islamic marketing literature, understand the phenomenon and related concepts and provide suggestions for future research.

Design/methodology/approach

The study uses an integrative review method that emphasizes summarizing and synthesizing the previous literature related to a phenomenon.

Findings

The findings indicate the emergence of five major themes, namely, Islamic marketing and its perspectives, activities in Islamic marketing, opportunities, controversies and challenges in Islamic marketing, Islamic principles and determinants of consumers’ behavior and awareness toward Islamic products. Each of the major themes consists of sub-themes discussed in detail in the results and discussion sections.

Research limitations/implications

Like other studies, this integrative literature review has some limitations. These include the methodology undertaken, the lack of explanation of inter-relationship among themes and lack of Islamic theory-based review. These limitations lead to future research directions.

Practical implications

Marketing managers need a thorough understanding of the Islamic standards and need to develop strategies. Further, there are inter-differences among Muslims, which need to be thoroughly understood by managers. Moreover, marketers can effectively use advertising in creating awareness and increasing demand of halal products.

Originality/value

This study provides an integrative review of the literature and synthesizes the Islamic marketing literature, which has not been done before.

Abstract

Purpose

Waqf has the quality of perpetuity so waqf properties cannot be sold, bought or given as a gift to others. Therefore, it is necessary to make sure that the property is fully used and properly managed by the Malaysian Islamic councils. To properly manage these properties, it is essential for the councils to have a proper reporting. Unfortunatley, this is not the case in the present situation for waqf. It was found that there is a lack of reporting on waqf matters. The purpose of this paper is to explore how the Islamic governance can contribute to the sufficient and adequate of waqf reporting.

Design/methodology/approach

This paper described what is being practised at present for waqf reporting. A series of Islamic governance literature was proposed in reinforcing waqf reporting.

Findings

This paper fulfils a gap in prior research by discussing several systems in Islamic governance to achieve transparency in waqf reporting. The findings of this paper may provide a significant contribution to any organisation that act as a trustee for waqf.

Practical implications

This paper provides an opportunity for further theoretical approach in defining and describing the role of governance in the reinforcement of waqf reporting. The paper has recommended several strategies towards better governance in Islamic council, and these suggestions can be offered to the councils for improvement.

Social implications

This research will be of interest to policy makers, especially Government and State Government. Given the current debate in Malaysia on the most appropriate forms of regulation for the Islamic sector, this study aims to provide valuable insights into the role of Islamic governance in the system of regulation.

Originality/value

This paper examined several governance system in Islamic governance to be applied in any Islamic organisation. This paper specifically deals governance issue that should be practised by present councils to prevent lack in waqf reporting. This system discusses the ways Islamic councils should perform since the system was originally implemented by a previous, distinguished caliph, Umar Al-Khattab.

Abstract

Purpose

Porous silicon (Si) was fabricated by using three different wet etching methods, namely, direct current photo-assisted electrochemical (DCPEC), alternating CPEC (ACPEC) and two-step ACPEC etching. This study aims to investigate the structural properties of porous structures formed by using these etching methods and to identify which etching method works best.

Design/methodology/approach

Si n(100) was used to fabricate porous Si using three different etching methods (DCPEC, ACPEC and two-step ACPEC). All the samples were etched with the same current density and etching duration. The samples were etched by using hydrofluoric acid-based electrolytes under the illumination of an incandescent lamp.

Findings

Field emission scanning electron microscopy (FESEM) images showed that porous Si etched using the two-step ACPEC method has a higher porosity and density than porous Si etched using DCPEC and ACPEC. The atomic force microscopy results supported the FESEM results showing that porous Si etched using the two-step ACPEC method has the highest surface roughness relative to the samples produced using the other two methods. High resolution X-ray diffraction revealed that porous Si produced through two-step ACPEC has the highest peak intensity out of the three porous Si samples suggesting an improvement in pore uniformity with a better crystalline quality.

Originality/value

Two-step ACPEC method is a fairly new etching method and many of its fundamental properties are yet to be established. This work presents a comparison of the effect of these three different etching methods on the structural properties of Si. The results obtained indicated that the two-step ACPEC method produced an etched sample with a higher porosity, pore density, surface roughness, improvement in uniformity of pores and better crystalline quality than the other etching methods.

Abstract

Purpose

Islamic finance and Halal product sectors are thriving successfully. This chapter is a general review of the perception of Asian consumers on Islamic finance and Halal sectors in the global Halal economy.

Methodology/approach

The first section will briefly describe the Halal concept in both Islamic finance and Halal industries, and the growth of both sectors in Asian countries. The second part highlights the review of Asian consumers’ perception towards Islamic finance products and Halal products.

Findings

The review found that the consumers’ perception towards the Islamic finance products and Halal products is distinctive. This is due to the diversity of Asian countries in terms of geography, religion, culture, ethnic, school of thoughts (madzahib), income per capita and government’s involvement.

Originality/value

The third part of the chapter concentrates on planning towards Halal marketing, which involves the move and future challenges in different layers of industries to gear up and strengthen the Halal economy.

Abstract

Purpose

Food industry players obtain the advantages of profits growth within the halal industry whereby the market is dynamic to generate profit. Hence, this study aims to analyse the perception of food manufacturers towards the adoption of the halal food supply chain (HFSC).

Design/methodology/approach

For this study, 103 halal food manufacturers in Malaysia were selected as respondents. Perceptions of respondents towards HFSC were recorded using a five-point questionnaire. The questionnaire was designed by authors and adapted from a previous study. The questionnaire was circulated by two experts with proficiency in this filed.

Findings

By conducting exploratory factor analysis, the study found the perception of food manufacturers, which is expected business benefits play an important role in the adoption of HFSC. Halal integrity becomes the second factor to lead the company to its adoption. Organizational readiness is the third factor that drives the company to adopt HFSC.

Research limitations/implications

Majority of the sample was responded by Bumiputera companies. The study suggests focussing the study for non-Bumiputera companies to examine their influence towards HFSC. Furthermore, future studies should explore different sectors of halal, such as pharmaceuticals, cosmetics, travel and tourism, logistics, finance and e-commerce. Moreover, ensuring the status of halal should be more emphasized in food chains; thus, the source of risk in HFSC should be explored to secure the integrity of halal.

Practical implications

The paper includes implications for the halal food industry, whereby the adoption of HFSC will contribute to the business benefits to create a more competitive advantage to the industry. Moreover, the implications of halal practice can create consumers’ trust on the halal product.

Originality/value

This paper fulfils an analysed need to study specifically on upstream parties by adopting HFSC.

Abstract

Purpose

The aim of this study is to discover the critical success factors (CSFs) for the Halal supply chain management because this area is gaining recognition. Plus, the aim is to use the CSFs for future research.

Design/methodology/approach

The study is based on the application of CSFs on the Halal supply chain. A comprehensive literature review is undertaken to discover the CSFs of conventional supply chain and to apply it to the Halal supply chain.

Findings

Government support, transportation planning, information technology, human resource management, collaborative relationship, Halal certification and Halal traceability are the CSFs for the Halal supply chain.

Research limitations/implications

This study only discusses the CSFs related to the Halal supply chain and ignoring other forms of Halal businesses. This study only concerns on English literatures and omit other languages. The study lacks empirical evidence and future research should be done to test the CSFs relevancy.

Practical implications

This study addresses stakeholders of the Halal supply chain CSFs, which have not been fully understand and appreciated.

Originality/value

CSFs concept has never been attempted on the Halal supply chain. Therefore, this study appraises the concept of CSFs and adds value to the knowledge on the Halal supply chain.

Abstract

Purpose

This study aims to discuss the challenges in implementing halal warehouse in the air cargo context along with the standard handling process for the storage of halal product for import and export purposes. This is vital to ensure that halal products do not get contaminated and should comply to halal logistics standard throughout the supply chain process.

Design/methodology/approach

This exploratory study adopts single case study to better understand the definition of halal warehouse, the challenges in implementing halal warehouse and also the standard handling process for the storage at the warehouse for import and export purposes. A well-guided case study protocol is followed.

Findings

Five categories have found to be the main challenges in implementing halal warehouse. They are coded as halal product trade, halal asset and facility, halal standard of procedure, human factor and perspectives between logistics provider and halal agencies. With regard to standard handling process for import and export purposes in airgo context with compliance to Shariah at the halal warehouse, there are seven main steps involved for import and nine steps involved for export.

Research limitations/implications

As this paper is among the pioneer study that looks into halal warehouse implementation, it has some limitations. Further empirical study in a bigger context may be performed quantitatively, and multiple case study approach may also be adopted to get deeper insight in understanding halal warehouse implementation domain of study.

Practical implications

This study contributes to the understanding on the gap in the field with adhering or complying with the practice. It will provide input to the authority in understanding the current limitation and suggestion by the practicing companies.

Social implications

Halal requirement in non-Muslim countries are not very well implemented and understood, whereby the understanding of the concept of Halalal Toyyiban throughout the supply chain process is critical. The main aim of halal logistics is to avoid cross contamination between halal and non-halal product during the transport, at the storage in warehouse and also in handling. This study contributes to the understanding of halal warehouse implementation.

Originality/value

There is a critical dearth of academic study that focuses on halal logistics specifically in transport and warehouse. This empirical case study provides basic understanding of implementing halal warehouse and presents the challenges and also required guidelines in handling halal product at the warehouse for both import and export purposes.

Abstract

Purpose

The purpose of this study is to examine and review tayyiban indicators in the context of halal food production. In Islam, food produced or manufactured must be halal and tayyiban. Even though both halal and tayyiban are always mentioned together in the Quran, the halal aspect is highlighted more than tayyiban. The discussion of tayyiban’s indicators is still vague.

Design/methodology/approach

The study was adopted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for the review of the current research which used two main journal databases, namely, Web of Science and Scopus. Accordingly, the search resulted in a total of 40 articles that can be systematically examined.

Findings

The results of review of these articles formulated five main themes: safety, nutrition, cleanliness, quality and authenticity. These five indicators are considered relevant enough in the context of halal food production to build a comprehensive tayyiban concept.

Originality/value

This study enriches the field of halal food research. The concept of tayyiban as a whole has been given limited attention in academic literature. At the end of this study, a number of recommendations are suggested for the reference of future scholars.
