The development of lanthanum-doped barium hexaferrite materials has attracted considerable attention in the field of functional materials, particularly as electromagnetic wave absorbers. This literature review aims to analyze advances in synthesis methods, structural characteristics, magnetic properties, and electromagnetic absorption performance of lanthanum-doped barium hexaferrite reported in various studies. Synthesis techniques such as sol–gel, coprecipitation, solid-state reaction, and hydrothermal methods are compared to evaluate their effects on crystallite size, morphology, and phase purity. Lanthanum doping is known to modify lattice parameters, reduce coercivity, and enhance complex permittivity and permeability, which play crucial roles in absorption mechanisms. Furthermore, variations in dopant concentration significantly influence reflection loss values and effective absorption bandwidth. The reviewed literature indicates that optimization of composition and synthesis routes can produce materials with high absorption capability, good stability, and strong potential for application in electromagnetic interference mitigation devices. This review is expected to serve as a conceptual reference for future development of lanthanum-doped barium hexaferrite–based electromagnetic wave absorbing materials. The comparative approach also highlights research challenges, industrial application opportunities, and future research directions relevant to the evolving demands of modern communication and defense technologies at both national and global levels.

This study comprehensively evaluates the quality of biomass briquettes produced from blends of coconut shell charcoal and sengon sawdust, using both carbonized and non-carbonized materials. Composite briquettes were fabricated with varying compositions and characterized through proximate analysis, calorific value, density, and burning rate measurements to determine their suitability as solid fuel. The results indicate that adding non-carbonized sawdust increases volatile matter content and burning rate but reduces the calorific value of the briquettes. In contrast, incorporating up to 10% carbonized sawdust significantly improves the calorific value to 6119.2 cal/g, approaching that of pure coconut shell charcoal (6352.2 cal/g), while maintaining a relatively high burning rate. Briquettes containing carbonized sawdust also exhibit low ash content, below 3%, and moisture content under 8%, meeting standard solid fuel quality requirements. These findings demonstrate that a strategic combination of carbonized and non-carbonized materials can produce hybrid biomass briquettes with optimized thermal performance, providing a promising, sustainable, and environmentally friendly alternative fuel for domestic and industrial applications.

Education in Islam plays a vital role in developing human potential holistically, where knowledge serves as the primary indicator of an individual's quality. This study aims to examine the virtue of knowledgeable people from the Quranic perspective, focusing on the theological and pedagogical analysis of Surah Al-Mujadalah verse 11. The method employed is descriptive qualitative through library research with a thematic exegesis (tafsir) approach. The results indicate that QS. Al-Mujadalah verse 11 establishes a hierarchy of human dignity based on the integration of faith and knowledge, rather than social or material status. These findings confirm that the elevation of rank encompasses a worldly dimension in the form of moral authority and an otherworldly dimension in the form of high positions before Allah. The implications of this research for contemporary Islamic education emphasize the importance of eliminating the dichotomy between religious and general sciences to cultivate the insan kamil (perfect human), who possesses a balance of intellectual intelligence, spiritual depth, and social responsibility. The study concludes that the virtue of knowledge in Islam is always grounded in transcendental values that bridge theory, faith, and practical deeds.
