Abstract

The surface coating of drill bits improves the tool life considerably and enhances the end product quality. The improved coating is desirable for long service operations. One of the methods to achieve this is to develop an interface layer between the coat and the tool base such that the transition of shear properties occurs across the interface layer. The application of duplex treatment (plasma pre‐nitriding before PVD TiN coating) to the tool surface becomes fruitful in this regard. In the present study, the wear properties of the duplex treated and untreated M7 HSS twist drill bits are examined. The wear tests are conducted on a dry base, and the feed rate and rotational speed are kept constant during the drilling tests. SEM and EDS are conducted to analyze the wear properties and metallurgical changes on the tool surface after the tests. It is found that the build up edge forms on the untreated tool surface, which in turn results in adhesion and abrasive wear. In the case of duplex treated drill bit, thinning of TiN coat is observed, but the coat is neither partially nor totally pealed off from the tool surface in the wear land.

Abstract

Friction material in an automotive brake system plays an important role for effective and safe brake performance. A single material has never been sufficient to solve performance related issues. Current research aimed to examine properties of Boron mixed brake pads by comparing them with the commercial brake pads. Friction coefficient of Boron mixed brake pads and commercial brake pads were significantly different and increased with the increase in surface roughness. The abrupt reduction of friction coefficient is more significant in commercial brake pad samples than in Boron mixed brake pad formulations. Fade occurred in commercial brake pad sample at lower temperatures. Boron formulations are more stable than their commercial counterparts.

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

Systematic reviews have contributed substantially to the development of knowledge in various academic fields and have helped discover new research potentials in a systematic manner. Specifically, this study aims to conduct a systematic bibliometric review to address ethical issues across the halal food supply chain (HFSC), as well as to identify the ethical challenges that food handlers face in ensuring authenticity, compliance with Shariah law and avoidance of contamination with non-halal ingredients in halal food products.

Design/methodology/approach

A bibliometric approach was used to analyse 263 publications from the Scopus database. The present research analysed the documents’ bibliographical data based on publication year, source title, country of origin, institution, authorship, keywords and citation count. The VOSviewer software was applied to perform citation and co-word analysis, as well as to construct bibliometric networks centred on the topic of ethical issues in the HFSC. This bibliometric review provides valuable insights for researchers to identify key publications and comprehend the foundational structure of the subject matter. It also helps guide future research into significant trends and new areas of study.

Findings

Citation analysis provides valuable insights into influential publications and the interconnectedness of research on HFSC. A co-word analysis revealed that discussions on ethics and integrity in the HFSC primarily revolved around the concept of halal and its implications, particularly in supply chain management. However, the limited frequency and prominence of these keywords suggests a scarcity of academic discourse on ethical matters in this field. Moreover, ethical considerations not only serve as a critical aspect of ensuring halal integrity but also emerge as a strategic imperative in marketing, brand management and the operation of global businesses.

Originality/value

This study addresses the need to examine the knowledge gap in the literature on ethical practices and issues in HFSC. Although there is a significant amount of academic writing in the halal context, there is a scarcity of research that specifically focuses on the ethical aspects of HFSC. This study also offers a framework for investigating the ethical practices and issues in HFSC.

Abstract

Purpose

This study aims to develop a measurement model of the halal supply chain resilience (HSCRES) index, which represents the capability of the supply chain (SC) to handle disruption caused by halal risks. A case study is conducted to apply the HSCRES index in the halal chicken SC in Yogyakarta, Indonesia, to test the proposed methodology.

Design/methodology/approach

A literature synthesis was conducted to establish the main capability and vulnerability factors and their relevant indicators. The indicators were validated using the confirmatory factor analysis approach. Then, applying an analytical hierarchy process involving ten experts – practitioners and academicians – the weight of each indicator was obtained. A survey of 20 employees of slaughterhouses, 35 sellers and 100 consumers was conducted to obtain the value of each indicator. Finally, the HSCRES index was calculated by comparing the total weighted capability value to vulnerability.

Findings

The results revealed that the resilience of halal chicken SC in Yogyakarta is at a good level, with an index of 3.459, and “halal team” is the most significant indicator. The findings also revealed several capabilities that need improvement, including dedicated halal facilities, employees’ halal competence and halal regulation. However, the lack of a halal certification board, lack of management commitment and packaging contamination were found as vulnerability indicators that need to be reduced.

Research limitations/implications

The case of this study is limited to the halal chicken SC in Yogyakarta, Indonesia. As a consequence, the obtained results are limited to a specific context. The application of this method to different areas and objects enables the establishment of different capability and vulnerability indicators.

Practical implications

The halal resilience measurement model offers a comprehensive understanding of the strengths and weaknesses of the HSC. The findings can help stakeholders improve preparedness for halal risks, deal with halal risks better and recover more quickly. Measuring the HSCRES index can be particularly useful for policymakers in developing evidence-based strategies to increase HSCRES.

Originality/value

The current study is the first to define and classify the contributing halal resilience attributes and also to calculate the halal resilience index.

Abstract

Purpose

This paper aims to find out the similarities and differences in meaning between the word “al amanah” and trust.

Design/methodology/approach

As a qualitative research, a content analysis is used in three stages. First, to elaborate the exegesis of the related Qur’anic verses together with the background narration or asbab un-nuzul if any and the Prophetic hadith where the word amanah is and to analyse and conclude its meanings. Second, the word “trust” is analysed based on the discussions in the literature which will lead to its specific meanings. Third, the concluded meanings of amanah and trust are to be compared to find out their similarities and differences.

Findings

Amanah and trust have the similar meanings: safe, confident, ability to fulfil the expectation of the person who trust, having competence or expertise to perform duty, deliver commitments, keep promises, work with a full of responsibility, integrity or obedient to moral principles. Differences: Amanah is not only oriented to humanity and responsibility in human’s relations but also, more importantly, to God Allah the Almighty, obeying His commands to make it as ibadah or acts of worshipping Allah the Almighty for maslahah or welfare for society.

Practical implications

The findings are considered important for companies or organisations. Before doing a commercial transaction or entering a contract or hiring an employee, they must study the quality of the counterparty whether they are capable to do the job as expected or not. In addition, the findings indicate that Islamic teachings concerning muamalat or Islamic rules for social dealings is universal in nature.

Originality/value

Being the first time to compare the word al amanah to trust, the findings point out the important elements to be evaluated when assigning a certain duty to an agent.
