This study aims to analyse cellulose fibres extracted from the pseudo-stems of Cymbopogon citratus and evaluate their properties in non-woven fabric production.
Abstract
Purpose
This study aims to analyse cellulose fibres extracted from the pseudo-stems of Cymbopogon citratus and evaluate their properties in non-woven fabric production.
Design/methodology/approach
The water retting method was used for fibre extraction, and intrinsic fibre qualities were examined to assess their suitability for textile applications. A thermal bonding technique, using a hot press machine and polylactic acid powder as a binder, was applied for non-woven fabric development.
Findings
The retted fibres had an average length of 156 mm and a fineness value of 5.73 tex. The fibre’s tenacity and elongation values were 1.33 gf/denier and 12.78%, respectively. Fourier transform infrared analysis confirmed the presence of major cellulose components. The fibre’s crystallinity and friction coefficient were 50% and 0.3, respectively. C. citratus fibre exhibited hygroscopic characteristics with a moisture regain of 10.65%. Experimental non-woven fabrics (70% C. citratus fibre, 30% polylactic acid powder) demonstrated consistent weight and thickness, with variations in tensile strength. Moisture regain values for non-woven fabrics were approximately 7.6%.
Originality/value
The features of C. citratus fibre, obtained with the water retting process, exhibited suitability for textile applications. Three experimental non-woven fabrics comprising of C. citratus fibre and polylactic acid powder were produced with three different pressing temperatures. The tensile strength properties of these fabrics were influenced by pressing temperature.

Abstract
Purpose
The purpose of this study is to analyse the characteristics of cellulose fibres derived from the pseudo-stems of Curcuma longa and to evaluate the properties of non-woven fabric produced using these fibres.
Design/methodology/approach
The fibres were extracted via a decortication method. The acquired intrinsic qualities of the fibres were used to assess the feasibility of using them in textile applications. The thermal bonding approach was used for the development of the non-woven fabric, using a hot press machine with low-melt polyester fibre as a binder.
Findings
The mean length of Curcuma longa fibres was determined to be 52.73 cm, with a fineness value of 4.00 tex. The fibres exhibited an uneven cross-sectional morphology, characterized by a diverse range of oval-shaped lumens. The fibre exhibited a tenacity of 1.45 g/denier and an elongation value of 4.30%. The fibres possessed a moisture regain value of 11.30%. The experimental non-woven fabrics had consistent weight and thickness, while exhibiting different properties in terms of tensile strength and air permeability, with Fabric C having the highest tensile strength and the lowest air permeability value.
Originality/value
The features of Curcuma longa fibre, obtained with the decortication process, exhibited suitability for textile applications. Three experimental non-woven fabrics comprising different compositions of Curcuma longa fibre and low-melt polyester fibre were produced. The tensile strength and air permeability properties of these fabrics were influenced by the composition of the fibres.

Abstract
Purpose
This study aims to examine the impact of halal tourism governance on halal tourist satisfaction by using halal tourism branding as a mediating role to increase tourist satisfaction.
Design/methodology/approach
Data is obtained through a questionnaire completed by 400 tourists who have traveled to visit halal tourism destinations on Madurese Island. The collected research data is tested by using partial least squares structural equation modeling (PLS-SEM).
Findings
The study revealed that halal tourism governance has positive and significant impact on halal tourist satisfaction and halal tourism branding. The study also revealed that halal tourism branding has no positive and significant impact on halal tourist satisfaction because the community thinks that halal tourism branding is common and commonplace.
Research limitations/implications
This research is on an Island-specific halal tourism destination, which means that the findings cannot be generalized to other geographical areas which have diverse cultures.
Practical implications
The study provides insight into halal tourism and destination governance, which is important for marketers, the Ministry of Tourism and local tourism officials to support halal tourism.
Originality/value
This paper fills a gap by presenting the first comprehensive overview of halal tourism governance that enhances ongoing discussions in the halal tourism field.

Abstract
Purpose
The research study intends to gain a better understanding of members' behaviors in the context of crowdsourcing contests. The authors examined the key factors that can motivate or discourage contributing to a team and within the community.
Design/methodology/approach
The authors conducted 21 semi-structured interviews with Kaggle.com members and analyzed the data to capture individual members' contributions and emerging determinants that play a role during this process. The authors adopted a qualitative approach and used standard thematic coding techniques to analyze the data.
Findings
The analysis revealed two processes underlying contribution to the team and community and the decision-making involved in each. Accordingly, a set of key factors affecting each process were identified. Using Holbrook's (2006) typology of value creation, these factors were classified into four types, namely extrinsic and self-oriented (economic value), extrinsic and other-oriented (social value), intrinsic and self-oriented (hedonic value), and intrinsic and other-oriented (altruistic value). Three propositions were developed, which can be tested in future research.
Research limitations/implications
The study has a few limitations, which point to areas for future research on this topic. First, the authors only assessed the behaviors of individuals who use the Kaggle platform. Second, the findings of this study may not be generalizable to other crowdsourcing platforms such as Amazon Mechanical Turk, where there is no competition, and participants cannot meaningfully contribute to the community. Third, the authors collected data from a limited (yet knowledgeable) number of interviewees. It would be useful to use bigger sample sizes to assess other possible factors that did not emerge from our analysis. Finally, the authors presented a set of propositions for individuals' contributory behavior in crowdsourcing contest platforms but did not empirically test them. Future research is necessary to validate these hypotheses, for instance, by using quantitative methods (e.g. surveys or experiments).
Practical implications
The authors offer recommendations for implementing appropriate mechanisms for contribution to crowdsourcing contests and platforms. Practitioners should design architectures to minimize the effect of factors that reduce the likelihood of contributions and maximize the factors that increase contribution in order to manage the tension of simultaneously encouraging contribution and competition.
Social implications
The research study makes key theoretical contributions to research. First, the results of this study help explain the individuals' contributory behavior in crowdsourcing contests from two aspects: joining and selecting a team and content contribution to the community. Second, the findings of this study suggest a revised and extended model of value co-creation, one that integrates this study’s findings with those of Nov et al. (2009), Lakhani and Wolf (2005), Wasko and Faraj (2000), Chen et al. (2018), Hahn et al. (2008), Dholakia et al. (2004) and Teichmann et al. (2015). Third, using direct accounts collected through first-hand interviews with crowdsourcing contest members, this study provides an in-depth understanding of individuals' contributory behavior. Methodologically, this authors’ approach was distinct from common approaches used in this research domain that used secondary datasets (e.g. the content of forum discussions, survey data) (e.g. see Lakhani and Wolf, 2005; Nov et al., 2009) and quantitative techniques for analyzing collaboration and contribution behavior.
Originality/value
The authors advance the broad field of crowdsourcing by extending the literature on value creation in the online community, particularly as it relates to the individual participants. The study advances the theoretical understanding of contribution in crowdsourcing contests by focusing on the members' point of view, which reveals both the determinants and the process for joining teams during crowdsourcing contests as well as the determinants of contribution to the content distributed in the community.

Abstract
Purpose
Researcher agreed that job performance has a positive effect on productivity as well as an organisation’s efficiency. Thus, this study aims to investigate the impact of mindfulness skill, inclusive leadership (IL), employee work engagement and self-compassion on the overall job performance of secondary school teachers in Hong Kong. It then evaluates the mediating effect of employee work engagement between the relationships of mindfulness skill, IL and job performance, as well as the moderate effect of self-compassion between the relationships of mindfulness skill, IL and employee work engagement.
Design/methodology/approach
The sample comprised 263 teachers working from three secondary schools in Sha Tin, Hong Kong. The data was then analysed using Smart PLS version 4.0.9.
Findings
The results showed significant positive relationships between mindfulness skill and IL towards employee work engagement and between employee work engagement and job performance; meanwhile, there emerged a significant effect on the relationship between mindfulness skill and IL towards job performance. Furthermore, this research has confirmed that self-compassion did not moderate the relationship between mindfulness skill, IL and employee work engagement, but employee work engagement plays a mediating effect on the relationship between mindfulness skill, IL and job performance.
Originality/value
This research has helped to fill the literature gap by examining the mediating roles of employee work engagement and mediator role of self-compassion in the integrated relationship of multi-factor and job performance. Examining the mediating role of employee work engagement has helped to enhance the understanding of the underlying principle of the indirect influence of mindfulness skill, IL and job performance. The result of this research shows that self-compassion plays a vital role in influencing the employees’ work engagement. Hence, it is important that companies design human resource management policy that enables self-compassion to be used as a consideration psychological-related strategy when structing organisation or teams. It is also crucial for top management and policymakers to define and communicate the organisation’s operating principle, value and goals.
