Abstract

Concern for the environment becomes a supporting factor in biocomposite research. Composite materials that previously used synthetic materials need to be swiftly transitioned into biocomposite materials, where one or all of its constituent materials originate from nature, making it more environmentally friendly and capable of being produced in large and sustainable quantities. However, in its application, biocomposite manufacturers still encounter several problems, especially in the field of mechanical strength. When compared to conventional composite materials, the mechanical strength of biocomposites is still lower. One effort that can be made to improve the mechanical strength of biocomposites is by treating natural fibers that will be used as reinforcement in the biocomposite with chemical processes. One easy and effective chemical treatment to apply is alkalinization using NaOH. This article will discuss a number of theories and research results regarding the influence of NaOH on the mechanical characteristics, specifically tensile strength, of natural fiber-reinforced biocomposites. The analysis process is carried out by gathering several reference sources, including books, scientific articles, and nationally and internationally recognized proceedings. All information from reference sources containing information about biocomposites, NaOH, natural fibers, and tensile strength is analyzed and rewritten in the form of an article.

Abstract

Learning innovation is one of the main keys in improving the quality of education in the digital era. This research aims to examine the utilization of Merdeka Mengajar platform by teachers as an innovative effort in the learning process in the classroom. This platform is designed to give teachers the freedom to design and implement learning that is more creative, adaptive, and in accordance with student needs. Through a descriptive qualitative approach, this study analyzes how the role of the Merdeka Mengajar Platform can assist teachers in supporting the implementation of the independent curriculum and find out how teachers use the features in the platform to create a more interactive and student-centered learning atmosphere. The results show that Merdeka Mengajar Platform helps teachers design more varied learning methods, provide wider access to materials, and increase student involvement in the learning process. In addition, this platform also supports collaboration between teachers and the continuous development of teacher professionalism. Thus, the use of Merdeka Mengajar has the potential to be an innovative solution in overcoming learning challenges in the digital era, especially in the context of independent and comprehensive learning.

Abstract

Environmental concerns have influenced a number of researchers to develop nature-based composite materials. These composite materials are composed of fibers and matrix, which are partially or completely derived from nature. Natural fibers are widely applied to reduce the utilization of synthetic fibers. However, natural fibers have hydrophilic properties that make it difficult to interact with the matrix, which tends to be hydrophobic. This condition results in the weak mechanical strength of natural fiber-reinforced composite materials. It is necessary to modify the surface of natural fibers, so that the interaction between natural fibers and the matrix can be improved, so that the resulting mechanical strength also increases. A number of analyses on natural fiber surface modification are discussed in this article to discuss the effect of each natural fiber surface modification method, as well as its characteristics when applied as reinforcement in composite materials. The analysis in this article includes several modification methods such as: alkalization, silane, and acetylation, as well as composite mechanical characteristics such as: tensile strength and elastic modulus. The analysis process is carried out by collecting several reference sources from books, and scientific articles accredited by national or international journals. Among the three methods analyzed, alkalization is the most widely applied method for natural fiber surface modification.

Abstract

This study aims to analyze the role of expository learning in encouraging student learning motivation in Fiqh subjects. The background of this study is the low motivation of students to learn, which has the potential to hinder their understanding of Fiqh material. The research method used is descriptive qualitative with observation, interview, and documentation techniques to collect data from students and Fiqh teachers. The results showed a significant change in students' learning motivation after the application of the expository method. Students became more active, enthusiastic, and showed increased participation in learning Fiqh. The systematic and clear application of the expository method proved effective in fostering students' interest and enthusiasm for learning. This study recommends the use of the expository method as one of the effective strategies to increase Fiqh learning motivation.

Abstract

Bamboo fiber-reinforced biocomposites (BFRCs) are increasingly attracting attention as sustainable alternatives to synthetic composites. This review article highlights the mechanical and thermal performance of bamboo fibers, the innovations in fiber treatment and processing techniques, and the challenges such as fiber-matrix incompatibility and environmental degradation. The study discusses advances in nanofiller integration, hybrid biocomposites, and life cycle assessment. Furthermore, it provides a future outlook on the standardization, biodegradability, and industrial scalability of BFRCs. The review concludes that BFRCs have significant potential for structural applications if key material and processing challenges are addressed.

Abstract

This study proposes an integration between science, specifically modern astronomy, and Qur'anic exegesis, aiming to bridge scientific understanding with spiritual values, particularly in the context of celestial phenomena. While stars in the Qur'an are often interpreted as symbols of God's power, scientific approaches to stellar phenomena frequently overlook this spiritual dimension. The research identifies a gap between modern astronomical knowledge and existing Qur'anic interpretations, and proposes an integrative approach that connects these two disciplines. Using a descriptive qualitative method and thematic exegesis analysis, the study demonstrates that Qur'anic verses about stars can be more deeply understood when enriched with modern scientific findings. The results reveal that this integrative approach not only enhances scientific comprehension but also deepens spiritual insight, fostering harmony between science and religion, and contributing to an educational paradigm that values both domains
