Abstract
Purpose
The purpose of this study is to the modeling of the dielectric barrier discharge (DBD) actuator on the Eppler 387 (E387) airfoil in low Reynolds number conditions.
Design/methodology/approach
A validated direct-forcing immersed boundary method is used to solve the governing equations. A linear electric field model is used to simulate the DBD actuator. A ray-casting technique is used to define the geometry.
Findings
The purposed model is validated against the former studies. Next, the drag and lift coefficients in the static stall of the E387 airfoil are investigated. Results show that when the DBD actuator is on, both of the coefficients are increased. The effects of the location, applied voltage and applied frequency are also studied and find that the leading-edge actuator with higher voltage and frequency has better improvement in the forces. Finally, the dynamic stall of the E387 with the DBD actuator is considered. The simulation shows that generally when the DBD is on, the lift coefficient in the pitch-up section has lower values and in the pitch-down has higher values than the DBD off mode.
Practical implications
It is demonstrated that using the DBD actuator on E387 in the low Reynolds number condition can increase the lift and drag forces. Therefore, the application of the airfoil must be considered.
Originality/value
The results show that sometimes the DBD actuator has different effects on E387 airfoil in low Reynolds number mode than the general understanding of this tool.

Abstract
Purpose
The development of waqf is growing rapidly. To maintain progress of waqf per se sharia, Muslim scholars try to present Islamic values (IVs) in activities and operations of waqf institutions. To find out implementation of IVs in waqf institutions, previous research was carried out as a guide for future research; this study aims to systematically review the literature.
Design/methodology/approach
This study draws on the implementation of IV in waqf institutions. Through the Preferred Reporting Items for Systematic Review and Meta-analysis for Protocol approach, 327 articles were collected, which were then extracted to gain lessons from various case studies related to problems in waqf institutions.
Findings
This study illustrates tawheed, justice, accountability, trust, mutual consultation, Allah consciousness, enjoin virtue and avoiding evil and objectives of shariah in waqf governance.
Research limitations/implications
The materials used in the systematic literature review were retrieved from few databases. The use of more academic databases will be better and more diverse, in addition to the repertoire of knowledge related to management and strategies at waqf institutions.
Practical implications
The identified values provide a framework for practitioners, policymakers and researchers to guide their efforts in developing and governing waqf institutions in accordance with Islamic principles.
Originality/value
The findings provide deep insights into the current state of IV in waqf institution in literature. This paper highlights many gaps in the literature and suggests directions for future studies to advance the understanding of implementation of IV. This study will help researchers to identify the new dimensions of research and contribute to the literature.

Abstract
Purpose
Islamic endowment (awqaf), particularly awqaf land, is one of the potential Islamic social assets to serve the public interest, particularly to provide public infrastructures such as business centers, public hospitals and airports. However, unfortunately, most of them are still unproductive lands, especially in the form of idle lands. One problem to use such unproductive awqaf lands is the lack of awqaf land model as the platform to use such awqaf lands. This paper aims to construct and propose a model called Sukuk-linked Awqaf (SLA) to use awqaf lands as an underlying for Sukuk issuance.
Design/methodology/approach
This paper constructs mechanisms and formulas of SLA by involving Sukuk issuer, awqaf management (Nadzhir), Sukuk investors and tenants of the infrastructure. In particular, the SLA model is proposed based on the unique characteristics of both awqaf asset and Ijarah (leasing) Sukuk, considers the intention of state-owned enterprise (SOE) to construct buildings to be rented to the tenant and to be owned by the awqaf manager and formulates equations and uses net present value theory to determine Nadzhir and Sukuk investors’ investment decisions.
Findings
Engaging awqaf land with SLA model can ease its benefit for the society. The model addresses the strategic roles of Nadzhir, SOE, investors and contractor in using awqaf land.
Research limitations/implications
The SLA model could ease related parties to use the awqaf land for the sake of public benefits.
Originality/value
To the best of the author’s knowledge, this is the first assessment on the potential implementation of Islamic hedging with a commodity as an alternative hedging in Indonesia.

Abstract
Purpose
Learning capability improves knowledge resources fosters innovative capabilities and firm competitiveness. The study aims to examine the human resource management (HRM) practice and employee creativity relationship using organizational learning capability (OLC) as a mediating variable.
Design/methodology/approach
Data were collected from 67 small-sized and 96 medium-sized firms. Confirmatory factor analysis was applied to establish construct validity and reliability. Structural equation modeling was used to evaluate the proposed model and hypotheses.
Findings
The results show that performance appraisal and employee creativity were positively related. Employee participation and employee creativity were positively related. Compensation and employee creativity were nonsignificantly related. OLC mediates the performance appraisal and employee creativity relationship. Similarly, OLC mediates the employee participation and employee creativity relationship. However, OLC did not mediate the compensation and employee creativity relationship.
Research limitations/implications
Due to the research’s SME focus and cross-sectional data, the finding’s generalizability will be constrained.
Practical implications
The findings of the study would be useful to policymakers, stakeholders and management of SMEs in developing a supportive learning climate that promotes experiential and continuous learning cultures to ensure strategic capabilities, sustainable competitive advantage and innovativeness.
Originality/value
The study contributes to the extant literature on OLC, HRM practices and employee creativity by empirically evidencing that OLC mediates the performance appraisal, employee participation and employee creativity relationship.

Abstract
Purpose
This study aims to evaluate the impact of Law No. 11 of 2018 on Islamic Financial Institutions in Aceh, Indonesia. It also aims to understand the balance between the economic rights of individuals under Shariah law and the broader concept of God’s rights, as interpreted by this legislation. In addition, the research argues that the implementation of Law No. 11 of 2018 is untimely, with a focus on examining its influence on the cumulative abnormal return (CAR) of Shariah banks and its slight contribution to the direct economic impact.
Design/methodology/approach
This study adopts a mixed-methods approach that integrates qualitative and quantitative analyses. The qualitative aspect uses a black-letter law approach for legislative scrutiny, whereas the quantitative aspect assesses economic indicators and firm performance using an event study analysis. The study also includes a two-tailed assessment to test hypotheses related to the law’s direct impact on institutional performance.
Findings
The study reveals that Law No. 11 of 2018 had minimal impact on national-scale corporate performance and a notable increase in poverty indices in Aceh, indicating a potential misalignment between the law’s intention and its economic consequences. The results also show the law’s ineffectiveness in significantly influencing the CAR of Islamic banks, highlighting a clash of norms and a lack of substantial economic substance in the implementation of Shariah compliance.
Research limitations/implications
This research is geographically and legally focused on Aceh, Indonesia, with a short-term analysis that may not fully capture the long-term impacts. It primarily considers the stock price performance of specific institutions for quantitative analysis and identifies potential clashes and disharmony-in-law implementation from a qualitative perspective.
Practical implications
The findings suggest the need for legal frameworks that better comply Shariah principles with economic realities. Regional governments should consider modifying policies to balance religious values and economic objectives.
Social implications
This research highlights the importance of balancing religious obligations with economic rights, indicating that strict interpretations of religious law can lead to adverse socioeconomic effects.
Originality/value
This study is unique in its comprehensive analysis of the convergence between religious law and economic rights, offering insights into the challenges faced in implementing Shariah-based economic policies in diverse economies, such as Indonesia.

Abstract
Purpose
This study aims to investigate the effects of zakat and business assistance on the growth and well-being of mustahiqs (zakat recipients). This study also investigates the impact of macroeconomic variables on the welfare of mutahiqs.
Design/methodology/approach
The partial least squares-structural equation modelling method is used in this quantitative study, examining data from 137 mustahiqs. The data was collected from seven zakat institutions, which run effective zakat programmes to empower mustahiqs.
Findings
Zakat empowerment programmes and business assistantships positively impact the growth of mustahiqs’ businesses, beneficial to their well-being. Nevertheless, their well-being is unaffected by the proxy of the macroeconomy.
Originality/value
This study adds to the zakat literature by identifying the relationship between zakat, business growth, macroeconomic conditions and mustahiq welfare. Accordingly, this approach was made by combining primary and secondary data. This research offers a unique measure of welfare based on the concept of the Islamic objectives (Maqasid al-Shariah).

Abstract
Purpose
This study aims to merge the world’s proven ways of housing finance, including musharakah mutanaqisah, housing cooperatives and real estate crowdfunding, to present an alternative housing unaffordability solution based on the Islamic finance principle. It is intended to reduce the burden of funding for both sides (consumers and developers) and create win–win chances for all stakeholders, including intermediaries. By moving away from debt financing and merging the features of crowdfunding and cooperative, it is hopeful that the burden of home ownership will no longer be the case.
Design/methodology/approach
This paper presents the opinions of potential Chinese homebuyers (minority Muslims and most non-Muslims) and a few industry experts toward the proposed model via a mixed research method.
Findings
According to the findings, the majority of respondents agreed with the proposed paradigm. Just concerned that China’s lack of community culture and trust could pose a major threat to implementation. However, this paper argues that Chinese local governments may perform pilot testing in places where Islamic culture is prevalent. Their unique community culture and fundamental understanding of Shariah law may affect the viability of the proposed model.
Originality/value
The proposed model would increase the applicability of Islamic finance as a way of protecting the social order of communities in the spirit of upholding justice and fairness. A new type of housing loan based on musharakah mutanaqisah may squeeze out the real estate bubble and provide stakeholders with a multidimensional investment channel. In particular, the study identifies the impact of Chinese Islamic financing on government and cultural needs. It presents possible challenges for implementing the proposed model in reality and helps bridge the gap between theory and practice.

Abstract
Purpose
The article examines Sheikh Ahmad Khatib Al-Minangkabauwi's initial concept of paper money, which in the early 20th century wrote Risala Raf'u Al-Iltibas.
Design/methodology/approach
This paper uses a qualitative approach based on the critical extraction analysis that can reveal a set of concepts related to the thoughts of Sheikh Ahmad Khatib Al-Minangkabauwi on paper money.
Findings
Through an attentive reading of Sheikh Ahmad Khatib Al-Minangkabawi, the authors can formulate several significant results: First, Ahmad Khatib Al-Minangkabawi applies two methods in studying critically on paper money, namely, the comparative law method and qiyas. Second, Ahmad Khatib believes that paper money has similarities with dinars and dirhams, namely its nominal value function. It is just that the existence of these values is different. Briefly, there are set law consequences for those who used paper money in economic activities, i.e. payment of zakāt on paper money applies when used as business capital.
Research limitations/implications
Sheikh Ahmad Khatib Al-Minangkabawi's work related to paper money is written heavily from the perspective of fiqh. Briefly, it is challenging to describe legal reasoning from work. As a result, articles are also thicker with fiqh analysis.
Practical implications
Sheikh Ahmad Khatib Al-Minangkabawi's view regarding paper money becomes the foundation for the theory of the value of money in Islam. However, it is rarely disclosed. In this regard, this paper can serve as the foundation of the value for money offered by scholars from Indonesia in the early 20th century.
Social implications
Money is not a commodity. Still, it must be positioned as capital to be productive. It finally becomes why trade is compelling and becomes the most practical reason for paying out zakāt.
Originality/value
It is not easy finding out articles that attempt to reveal the concept of classical ulemas or clerics from Indonesia relating to paper money. This article manages to identify that, and at the same time, becomes a novelty.

Abstract
Purpose
The purpose of this paper is to improve the critical thinking of biology students of STKIP Hamzanwadi Selong on an environment course through the implementation of Problem-Based Learning (PBL) and Group Investigation (GI) through Lesson Study.
Design/methodology/approach
This study employed a descriptive qualitative method. The subjects of the study were 73 freshmen biology students academic year 2013/2014 who were divided into two classes. The Lesson Study was conducted in 16 cycles, comprising Plan, Do, and See stages. The instrument of the study used to measure the students’ critical thinking was an essay test which covered several criteria of critical thinking adapted from SOLO Taxonomy.
Findings
The implementation of PBL and GI encouraged the students to think critically through planning, arguing, stating questions and problems, and analysing and providing solutions to the surrounding environmental problems.
Originality/value
This study depicted Lesson Study activity on an environment course which focused on the students’ critical thinking activity through the integration of PBL and GI. The learning was conducted through Lesson Study and was based on the environment. The crucial value of the Lesson Study was the lecturers showed more attention to the students since they wanted to know the students’ learning style and what made them learn.

Abstract
Purpose
Ubiquitous penetration of the internet fuelled by the interactive nature of digital media has created a new genre of entrepreneurs who leverage social media to propel their businesses. This study aims to explore the transformation of one such digital entrepreneurial cohort: Food YouTubers (YTs), who have metamorphosed from being mere content creators to entrepreneurs in the context of an emerging economy.
Design/methodology/approach
The authors invoke a qualitative interpretive phenomenological approach to unravel the entrepreneurial transition process. A combination of personal interviews and open-ended surveys is used to collect relevant data from 14 digital entrepreneurs. The transcripts are analysed to extract meaningful codes and themes.
Findings
The study shows that these entrepreneurs’ innovativeness and readiness to meet the real-time demands of their customers made their ventures a runaway success. This is the first study to target food YTs in India, an emerging economy. While the study is exploratory in nature, it provides basic insights into the transition of a novel group of influencers into entrepreneurs.
Originality/value
To the best of the authors’ knowledge, this is the first study of its kind to analyse the transition of YouTube influencers into entrepreneurs in emerging economies, as it relies more on entrepreneurial activities for their economic and social well-being.
