Abstract
In this article a proposal of a non‐traditional methodology in achieving optimal flexibility with minimal inventory risk will be applied. The non‐traditional methodology will be able to achieve different levels of the production schedule changes with maximum flexibility and minimal inventory risk. The basic principle, implementation methodology as well as its effectiveness and benefits will be discussed. In order to overcome the risk of achieving flexible manufacturing or enhancing supply chain management, this article will address issues on methods to accommodate production sequence changes which include total production quantity change in a short lead time. The study uses the Family Ordering System methodology which has proven capable in solving manufacturing flexibility issues by reducing the total manufacturing lead time. Family Ordering System provides the flexibility of model changes and reduces production line stoppage as a result of part shortage by carrying extra inventory of unique parts.

Abstract
Presents a study on the application of boundary element method (BEM) to the solution of elastohydrodynamic lubricated hard rolling contacts in comparison with a solution using finite difference method (FDM). The developed program for the solution of Reynolds equation and the elasticity equation give results of pressure distribution and the lubricant film thickness for steady state, isothermal Newtonian lubricant behavior. Compares the BEM results and the computer effort with the solution using FDM. Uses an iterative Newton‐Raphson method to solve the non‐linearity of the problem. Discusses the effects of Hertzian pressure and rolling speeds on film thickness and pressure distribution. The numerical scheme of BEM has proved to have the advantage of being very effective and optimum in terms of accuracy, less computational effort and good constancy compared to other applied numerical techniques.

Abstract
Purpose
The purpose of this paper is to investigate the fracture properties of hybrid woven bamboo (WB)/woven e-glass (EG) fiber composites with various layer arrangements. This paper utilized a specific type of bamboo species named Gigantochloa Scortechinii (Buluh Semantan).
Design/methodology/approach
In these experiments, unsaturated polyester, woven EG and WB fibers were prepared through the hand lay-up technique. The composite bamboo strips were prepared in 1.5 mm thickness. The strips are woven to make a single layer. The layer was then laminated into several thicknesses. The specimens were then characterized using compact tension fracture tests.
Findings
The fracture toughness of 12–14 MPa was obtained. These findings suggest that this hybrid bamboo composite provides superior fracture strength that is equivalent with steel alloy and is extremely a good alternative for reinforcing fibers to combat fracture failures of materials and structures.
Originality/value
In this paper, experimental determination of newly developed composite made of WB and woven EG is presented.

Abstract
Purpose
This study aims to determine the impact of attitude toward content creators, subjective norm and perceived content quality in affecting people’s intention and behavior to watch videos posted on YouTube in Indonesia.
Design/methodology/approach
Using questionnaire, data from the total of 112 individuals living in Indonesia were gathered in this study, and these respondents are individuals who have been watching YouTube contents at least 3 h a day for the past eight months. Moreover, all of these data were processed and analyzed using PLS method to determine the impact given by one variable toward the other.
Findings
Based on the results of the analysis, the authors concluded that both factors, namely, content credibility and perceived content quality, play significant and positive roles in determining people’s intention to watch – and ultimately behavior to watch – contents or videos published on YouTube, with the former turned out to be the stronger predictor.
Originality/value
The current study attempts to modify and merge both the concept of theory of reasoned action and product quality theory to explain Indonesians’ behavior toward watching contents published on YouTube, and to the best of the authors’ knowledge, this type of studies is still in rarity.

Abstract
Purpose
This study aims to explore the impact of external stimuli – perceived product quality, advertising value and the halal logo – on Muslim consumers’ attitudes and purchase intentions, using the stimulus–organism–response (S-O-R) model in accordance with its traditional framework. Additionally, it seeks to analyze and compare the purchasing behaviors of male and female consumers in the context of halal cosmetics.
Design/methodology/approach
An online survey using purposive sampling was conducted with 635 Muslim consumers in Indonesia to test the proposed model using structural equation modeling.
Findings
The results demonstrated that perceived quality, advertising value and the halal logo significantly enhance attitudes toward halal cosmetics. However, when it comes to purchase intention, only advertising value and the halal logo directly influence it. In terms of gender comparison, the study found significant moderation of gender in the relationship between advertising value and attitude, with this influence being more pronounced among male consumers. The findings indicate that both perceived quality and the halal logo significantly and positively impact attitudes and purchase intentions for both male and female Muslim consumers, with a notably stronger effect observed among females. Interestingly, the influence of advertising value on attitude is significant only among male consumers, highlighting a gender-specific response to advertising stimuli.
Practical implications
The study suggests that businesses operating in the halal cosmetics market should focus on enhancing consumers’ perception of product quality through halal certification. Additionally, they should tailor their marketing strategies based on gender differences and prioritize the prominent display of the halal logo. These actions are expected to positively influence the attitudes and purchase intentions of Muslim consumers in Indonesia.
Originality/value
This study introduces a novel approach to the understanding of consumer behavior toward halal cosmetics by emphasizing the frequently overlooked role of external influences through the S-O-R theory. In contrast to earlier research, which predominantly focused on internal factors and religious compliance, this study explores the impact of marketing interventions such as product quality, advertising and the presence of a halal logo. Additionally, it distinguishes itself by examining the purchasing behavior of both female and male consumers in the realm of halal cosmetics.

Abstract
Purpose
This study aims to investigate the effect of temperature applied at the initial deposition of Aluminium Nitride (AlN) thin-film on a silicon substrate by high-power impulse magnetron sputtering (HiPIMS) technique.
Design/methodology/approach
HiPIMS system was used to deposit AlN thin film at a low output power of 200 W. The ramping temperature was introduced to substrate from room temperature to maximum 100°Cat the initial deposition of thin-film, and the result was compared to thin-film sputtered with no additional heat. For the heat assistance AlN deposition, the substrate was let to cool down to room temperature for the remaining deposition time. The thin-films were characterized by X-ray diffraction (XRD) and atomic force microscope (AFM) while the MIS Schottky diode characteristic investigated through current-voltage response by a two-point probe method.
Findings
The XRD pattern shows significant improvement of the strong peak of the c-axis (002) preferred orientation of the AlN thin-film. The peak was observed narrowed with temperature assisted where FWHM calculated at 0.35° compared to FWHM of AlN thin film deposited at room temperature at around 0.59°. The degree of crystallinity of bulk thin film was improved by 28% with temperature assisted. The AFM images show significant improvement as low surface roughness achieved at around 0.7 nm for temperature assisted sample compares to 3 nm with no heat applied.
Originality/value
The small amount of heat introduced to the substrate has significantly improved the growth of the c-axis AlN thin film, and this method is favorable in the deposition of the high-quality thin film at the low-temperature process.

Abstract
Purpose
The purpose of this study is to examine the effect of knowledge and attitude on firms’ commitment to Halal standard practices in a developing nation’s food sector. Additionally, the moderating effect of gender on this association is explored.
Design/methodology/approach
The partial least squares-structural equation modelling (PLS-SEM) technique is used to analyse the results of a self-administered questionnaire completed by 200 internal Halal executive officers of multinational corporations and small and medium enterprises in a developing nation’s food sector.
Findings
The empirical findings reflect the significant role of attitude in influencing firms’ commitment to Halal standard compliance in the food sector and thereby contribute towards improving organisational performance. In more detail, male respondents were more likely than female respondents to have a favourable attitude toward Halal standards in the food industry. Additionally, a positive attitude can influence how employees are judged on their adherence to Halal standard processes. This encouraging outcome is the result of joint efforts by all government agencies, statutory bodies and private organisations involved in Halal practices.
Practical implications
Halal food producers should engender greater commitment to Halal standard practices within the buyer–supplier relationship due to the crucial nature of Halal concerns in food production. They should place a premium on strategic planning to safeguard the integrity of Halal food for consumption.
Originality/value
This study considerably advances the existing body of knowledge by applying the consumer decision model to explain the relationships between knowledge, attitude and firms’ commitment to Halal standard practices in the food industry of a developing nation, with gender serving as a moderating variable. The empirical findings addressed the research gap by offering noteworthy insight into a subject that has received minimal attention in prior studies.

Abstract
Purpose
The purpose of this paper is to examine the structural relationship between the emotional and social support provided for individuals with caring responsibilities for elderly relatives, and the quality of care actually delivered. In addition, the moderating role of gender is explored.
Design/methodology/approach
A quantitative research design was utilised in which 200 usable questionnaires were collected from 250 respondents comprised of young adults who adopt a caregiving roles in respect of elderly parents or other close elderly relatives. The structural equation modelling (SEM) technique was selected for data analysis, and the Analysis of moment structure software version 21 was used.
Findings
The SEM results revealed that emotional support for caregivers was the most important predictor affecting the intergenerational care of multi-ethnic elderly people. Additionally, a moderation analysis revealed that the relative influence in this connection was more pronounced among female caregivers. An increase in the emotional support received by the recipient was found to enhance the level of the relationship, and to result in closer intergenerational ties in the care of the multi-ethnic elderly. Furthermore, the receipt of social support positively influences the judgement of an individual, and expands that person’s social network, which can subsequently have a favourable impact on the way in which one fulfils their caring role. The significant effect of social support provided for intergenerational caregivers in the context of the multi-ethnic elderly was higher in the group of male caregivers than in the group of female caregivers.
Practical implications
This study sends a strong message to policy-makers in developing countries about the need to consider within their National Policy for the Elderly, improvements in the national action plan for a holistic and integrated approach to ensure the well-being of caregivers and the elderly.
Originality/value
The results of the study help young adults to understand the importance of emotional and social support in boosting their relationships with parents and families and motivating intergenerational efforts in the care of the multi-ethnic elderly. Harmony within families is an important ideal in any circumstance, but in the scenario of ageing family members it may be even more essential to try to achieve it.

Abstract
Purpose
The purpose of this paper is to explore the best practices of school leaders, teachers, pupils, parents and the community in selected transformed schools in Selangor, Malaysia.
Design/methodology/approach
This qualitative multiple-case study explores the best practices in two selected transformed schools through in-depth interviews, observations and document reviews. The data were collected from 2 school heads, 6 teachers with administrative responsibilities and 20 teachers. The themes were elucidated via open, axial and selective coding based on the grounded theory approach.
Findings
The analysis identified various best practices exhibited by school leaders, teachers, pupils, parents and the community. Four themes were found to be common as best practices in both selected schools, which were adaptive and multi-dimensional leadership, winning-the-hearts, extensive use of Information and Communication Technology in school operations, and a culture of acquiring and sharing professional knowledge. The unique theme for School A was the emphasis on the social, emotional and ethical well-being of the students, while extensive parental involvement and support was a unique theme identified in School B.
Research limitations/implications
The findings of this paper may be used as guidance tool for policy makers and educational planners regarding school transformation in Malaysia, and as well as in other countries. Such practices can be learned, adapted and replicated by other schools in order to transform. The findings also have direct implications to current teachers, school leaders, parents and the community.
Originality/value
This study contributes to the growing body of research on the best practices and school transformation in Malaysian transformed schools. There is a decisive need to explore the best practices of transformed schools in Malaysia based on their own cultural and contextual needs in order to help schools that aspire for transformation.

To develop a high‐order compact finite‐difference method for solving flow problems containing shock waves.
Abstract
Purpose
To develop a high‐order compact finite‐difference method for solving flow problems containing shock waves.
Design/methodology/approach
A numerical algorithm based on high‐order compact finite‐difference schemes is developed for solving Navier‐Stokes equations in two‐dimensional space. The convective flux terms are discretized by using advection upstream splitting method (AUSM). The developed method is then used to compute some example laminar flow problems. The problems considered have a range of Mach number that corresponds to subsonic incompressible flow to hypersonic compressible flows that contain shock waves and shock/boundary‐layer interaction.
Findings
The paper shows that the AUSM flux splitting and high‐order compact finite‐difference methods can be used accurately and robustly in resolving shear layers and capturing shock waves. The highly diffusive nature of conventional flux splitting especially on coarse grids makes them inaccurate for boundary layers even with high‐order discretization.
Originality/value
This paper presents a high‐order numerical method that can accurately and robustly capture shock waves without deteriorating oscillations and resolve boundary layers and shock/boundary layer interaction.
