Development of a Chef Uniform Ethics Learning Kit Using Augmented Reality (AR) for Hearing Impaired Students in Polytechnics
Full text linkHearing-impaired students face difficulties in understanding the ethics of wearing the chef uniform due to limited communication, lack of standardized sign language terms, and insufficient interactive teaching aids. These challenges reduce their understanding and motivation in learning, highlighting the need for more visual and engaging learning tools. The purpose of this study is to develop a chef uniform ethics learning kit using Augmented Reality (AR) for hearing-impaired students, with a focus on enhancing their visualization, understanding, and motivation through a more interactive and accessible learning experience. The study employs a Design and Development Research (DDR) approach and uses the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model as the instructional design framework. The sample consists of 10 hearing-impaired students enrolled in their second semester of the “Sijil Khas Operasi Katering” program at Politeknik Ibrahim Sultan (PIS), Johor. The findings indicate that the use of the AR-assisted learning kit significantly improves the visualization, understanding, and motivation of hearing-impaired students in understanding chef uniform ethics. The levels of visualization, understanding, and motivation of hearing-impaired students demonstrated high achievements after using the AR-assisted learning kit. Additionally, no significant differences were found between male and female hearing-impaired students, suggesting that the AR-assisted chef uniform ethics learning kit benefits all hearing-impaired students equally, regardless of gender. The results of this study highlight the potential of AR in supporting inclusive education and improving learning outcomes for students with special needs, offering an innovative approach for future educational tools in vocational programs. In conclusion, this study emphasizes the positive impact of AR in creating an inclusive, engaging, and effective learning environment for hearing-impaired students, in alignment with the goals of inclusive education in Malaysia.

Full text linkMalay:
Artikel ini bertujuan untuk meninjau sejarah dunia melalui lensa pandangan alam Melayu sebagai satu usaha epistemologi alternatif dalam memahami naratif sejarah global. Wacana sejarah dunia sering didominasi oleh naratif Eurocentrik yang meminggirkan suara dan pengalaman peradaban bukan Barat, termasuk tamadun Melayu. Melalui pendekatan analisis kualitatif berbentuk kajian kepustakaan dan pemikiran kritikal, artikel ini mengemukakan pandangan alam Melayu sebagai satu kerangka epistemologi yang berasaskan nilai, tradisi, dan pengalaman lokal yang unik. Penulisan ini menelusuri bagaimana alam Melayu membentuk interaksi antarabangsa melalui jaringan perdagangan, penyebaran Islam, dan hubungan diplomatik sejak zaman silam. Artikel ini mencadangkan bahawa epistemologi Melayu mampu menyumbang kepada penulisan sejarah dunia yang lebih inklusif, adil, dan pelbagai suara, sejajar dengan usaha dekolonisasi ilmu dan pengiktirafan terhadap naratif alternatif dalam wacana akademik global.

This article aims to explore world history through the lens of the Malay worldview as an effort towards an alternative epistemology in understanding the global historical narrative. The discourse on world history is often dominated by Eurocentric narratives that marginalize the voices and experiences of non-Western civilizations, including the Malay civilization. Through a qualitative approach involving literature review and critical thinking, this article presents the Malay worldview as an epistemological framework grounded in unique local values, traditions, and experiences. This paper traces how the Malay world shaped international interactions through trade networks, the spread of Islam, and diplomatic relations since ancient times. The article argues that Malay epistemology can contribute to a more inclusive, equitable, and multi-voiced account of world history, in line with the broader efforts of decolonizing knowledge and recognizing alternative narratives within global academic discourse
Community Empowerment Through Social Service: The Role of Sacrificial Animal Slaughter in Strengthening Solidarity and Economic Resilience in Sidoharjo Village, Pulung Ponorogo
Full text linkThe slaughter of sacrificial animals (qurban) is a religious practice in Islam that carries profound spiritual significance alongside its broad social and economic dimensions. This study aims to analyze the implementation of social service activities through qurban slaughter in Sidoharjo Village, Pulung, Ponorogo, and its impact on strengthening social solidarity and empowering the local economy. Using a qualitative approach with a case study method, the research involved direct observation during the activity, in-depth interviews with organizers, community leaders, and beneficiaries, as well as documentation analysis. The findings reveal three key impacts of qurban activities in Sidoharjo Village. First, in the social aspect, the activity fosters community solidarity through active participation in all stages, from fundraising and animal slaughter to meat distribution. Second, the meat distribution contributes significantly to food equity, particularly for underprivileged groups who have limited access to protein sources. Third, the activity positively impacts the local economy, benefiting livestock farmers who experience increased demand for sacrificial animals. Moreover, community involvement in managing the event creates temporary economic opportunities, such as roles in logistics and slaughter operations. This study highlights the importance of qurban slaughter as a community service model that integrates religious values with social harmony and economic empowerment. The findings provide valuable insights for implementing similar programs in other communities, emphasizing structured management to maximize their impact
Heat Transfer Enhancement in Single Heat Exchanger 2D Pipe Using Rod with Different Angles Based on Computational Fluid Dynamics Study
Full text linkThe current numerical study focuses on the statistical investigation of the airflow and the improvement of the heat transfer rate by forced convection of a single pipe in a heat exchanger by the inclusion of a rod. Using the finite volume method by numerical simulation the flow characteristics of the working fluid with enhanced heat transfer are numerically studied. Homogeneous heat flux is applied to the upper and lower walls of the pipe. More for the Reynolds number range (9000-18000) the effect of inserting a rod inside the tube at different oblique angles (40°,50°, and 60°) was examined. Numerical results revealed that the transfer coefficient rate (Nusselt number) increase in the tube inserted into the rod is higher compared to the normal pipe. In addition, the results also showed that when the angle of inclination of the rod in the single-pipe heat exchanger is gradually increased the Nusselt number increases. The Nusselt number maximum value was shown at the 60° angle of the rod insert. Because of the resistance of a bigger flow, the friction factor was found by using the rod inserts at (60°) and pitch distance (0.04 m). For a minimum slant angle of (40°) and a pitch distance of (0.04 m), the maximum value of the performance evaluation criteria (PEC) was stated. In comparison to the smooth tube, the percentage of fluid velocity distribution rises by (50,57, and 63%) at the angle of inclination of the rod (40°, 50°, and 60°), respectivel
Reconciling Faith and Reason: Al-Bouti’s Defence of Roger Garaudy in the Context of Apostasy and Islamic Jurisprudence
Full text linkThis paper is, in a way, an assessment of an apologia of the offence of hadd written by Muhammad Said Ramadan al-Bouti (1929-2013) to defend Roger Garaudy (1913-2012) against the accusation of apostasy. It analyses the evidence presented by al-Bouti to support his arguments for exonerating Garaudy. Al-Bouti was a prominent Syrian scholar and one of the most influential Islamic jurists in the contemporary Arab world, and a Shafi’i jurist who believed in applying independent reasoning in his interpretation of rulings. In his efforts to preserve the Sufi concept of ‘interior form’ and ‘exterior behaviour’, al-Bouti combines the spirituality of Sufism with traditional legal rulings of fiqh to derive the power of a believer’s conformity with the Sharia. It was this hypothesis of reconciling Islamic mysticism with fiqh that helped his work to gain currency in the Islamic world. Roger Garaudy (1913-2012), on the other hand, was a French Marxist philosopher who converted to Islam in 1982/83, at the age of 70. His conversion to Islam was perceived in the West as indicating “the superiority of Islam over the West”. For this reason, the attack of Western scholars on him was interpreted as part of the West’s attack on Islam. However, Garaudy faced widespread criticism in the Muslim world after publishing his book Islam, to the extent that Muslim authors began to question the orthodoxy of his beliefs. The strongest assault came from the Saudi journal al-Mujallah in 1996, after Garaudy was interviewed by its correspondent in Paris. The article claims that Garaudy’s conversion to Islam was more or less superficial. This paper introduces brief details of al-Bouti’s life and his intellectual impact. Similarly, it highlights the Garaudy affair, his impact in the Muslim world, and the historical origin of the kufr accusation. Finally, it explores the main argument of al-Bouti in his defense case, making particular reference to the al-Mujallah article.

This study aims to explore the role of the Qur’an in shaping social emotions among adolescents, with a particular focus on how Qur’anic teachings can cultivate positive behaviours and social values in today’s youth. Adolescents represent a group undergoing a transitional phase in life and are often exposed to various external influences that, consciously or unconsciously, shape their values and moral development. In this context, the Qur’an, as the primary source of Islamic teachings, holds significant potential in guiding the formation of sound social ethics, including values such as honesty, respect, responsibility, and compassion. This study analyses selected Qur’anic verses related to moral and emotional aspects and examines how these teachings can be translated into the daily lives of adolescents through education, family, and community engagement. Employing a library-based research design, this study reviews relevant past literature and further evaluates the effectiveness of Islamic educational and dakwah programmes in nurturing these values among youth. The findings of this study are expected to contribute to enhancing adolescents’ social-emotional awareness and strengthening the application of Islamic teachings in their everyday lives
Cu and CuO Nanoparticles in Heat Transfer Applications: A Comprehensive Review
Full text linkThis review highlights the role of Copper (Cu) and Copper Oxide (CuO) nanoparticles in enhancing heat transfer through mono, binary, and ternary nanofluids. Mono nanofluids consistently improved thermal conductivity, viscosity, pressure drop, and heat transfer coefficient, with higher gains at higher concentrations. Binary systems showed synergistic effects, with CuO–MWCNT yielding maximum conductivity, CuO–TiO₂ showing Newtonian behavior, and Cu with Al₂O₃ and TiO₂ achieving peak conductivity at a 40:40:20 ratio. Ternary mixtures of Cu, CuO, and Al₂O₃ offered further conductivity enhancement but with larger pressure drops, notably at 60:20:20. Overall, nanoparticle selection, base fluid, and mixing proportion are key to balancing thermal performance with hydrodynamic penalties.
Glycerolysis-Based Reduction of Free Fatty Acids in Crude Palm Oil (CPO) for Cost Effective Biodiesel Pre-Treatment
Full text linkThe high content of free fatty acids (FFA) in crude palm oil (CPO) presents a significant challenge for biodiesel production. This study investigates the glycerolysis pretreatment method using crude glycerol and potassium hydroxide (KOH) to reduce FFAs. Experiments were performed at varying molar ratios (1:3 to 1:9) and temperatures (60°C to 80°C). Results showed optimal FFA reduction at a 1:7 molar ratio and 80°C, reducing FFA below 5% within 60 minutes. FTIR analysis confirmed FFA conversion. The reaction followed a pseudo-second-order kinetic model (R² = 0.9832). Viscosity and density of the oil improved to 41.2 mPa·s and 0.886 g/cm³, respectively. These findings demonstrate that glycerolysis is a promising, eco-friendly, and cost-effective solution for pretreating high-FFA feedstock in biodiesel production
