This study contributes to the study of Islamic anthropology and living sunnah, affirming cultural acculturation as a form of religious expression that is alive and relevant.

Carbonate rocks are one of the most important geological resources with a significant role in various industrial sectors, particularly as the main raw material in cement, lime, and construction industries. This study aims to review the characteristics, quality, and industrial potential of three major carbonate rock types—limestone, dolomite, and marble—based on relevant scientific literature. The research employed a literature review method using a qualitative-descriptive approach through analysis and synthesis of previous studies. Data were collected from scientific publications addressing the mineralogical, chemical, and physical aspects of carbonate rocks and their implications for industrial performance. The findings indicate that the quality of carbonate rocks is largely determined by mineral composition (calcite and dolomite), chemical purity (CaO and MgO), and the presence of impurities such as silica, alumina, and iron oxides. High-purity limestone rich in calcite is identified as the most efficient raw material for cement and lime industries due to its stable processing behavior and lower energy requirements. Conversely, dolomite with high magnesium content requires process adjustments to prevent excessive MgO formation during calcination. Marble, both in natural and waste powder form, shows promising potential as a supplementary material in sustainable cement production. Overall, this study emphasizes that understanding the mineralogical and chemical variations of carbonate rocks is essential for optimizing their processing strategies and promoting sustainable industrial utilization

This study aims to explore the symbolic meaning of the siraman ceremony in Javanese culture and interpret its values ​​in light of the Catholic faith, particularly regarding the sanctity and blessings of the sacrament of marriage. The siraman tradition is understood not merely as a cultural ritual, but as a process of physical and spiritual purification imbued with spiritual symbolism, such as the use of water from seven springs and the granting of parental blessings. This study uses a qualitative approach with a literature review method through analysis of Church documents, Javanese anthropological literature, and relevant research. The results indicate that the meaning of purification in siraman is closely related to the symbolism of baptismal water in the Catholic tradition, while the prayer of parental blessing aligns with the concept of blessing as a manifestation of God's grace in the family. Through the inculturation perspective emphasized in Gaudium et Spes and Ecclesia in Asia, siraman can be understood as a form of harmonious dialogue between faith and culture without compromising the purity of Church teachings. This study concludes that the siraman ceremony can enrich the experience of the sacrament of marriage for Javanese Catholics, while strengthening their identity as individuals of faith and culture.

Parenting plays a crucial role in shaping a child's personality and religious values ​​from an early age. This study aims to examine the concept of parenting from an Islamic perspective, particularly according to the views of Imam Al-Ghazali, a prominent Islamic scholar and thinker. The method used was a literature review with a descriptive analytical and historical approach. The results show that Islamic parenting, according to Al-Ghazali, is based on the principles of monotheism, faith, and noble morals derived from the Quran and Sunnah. Al-Ghazali viewed children as a trust from Allah, born in a state of fitrah (purity) and as potential beings who are the hope of the community. Educating children must be done from an early age because childhood is a golden period that is very decisive in character formation. The parenting methods recommended by Al-Ghazali include: (1) the habituation method to shape character through continuous practice; (2) the role model method, where parents serve as direct role models for children; (3) the storytelling method to instill moral values; (4) the advice method with a compassionate approach; and (5) reward and punishment methods applied wisely. Al Ghazali's parenting concept emphasizes the importance of parents' role in creating a conducive environment for children's spiritual, moral, and social development, which not only impacts worldly life but also the afterlife. This research contributes to the idea of ​​the urgency of implementing Islamic teachings in educating and raising children in the digital era, which is full of various challenges.

This study aims to analyze the narrative dissonance in the corporate communication of the Aqua brand, especially in the context of the crisis of meaning that arises between claims of natural purity and technical findings related to the use of borewells in the production process. Using a qualitative approach through content and narrative analysis, the study integrates two main theoretical frameworks: the Narrative Paradigm (Fisher, 1984) and Image Repair Theory (Benoit, 1995). The analysis focused on how companies are building, maintaining, and renegotiating their corporate narrative amid public pressure and consumer expectations. The results show that the legitimacy crisis arises due to the symbolic mismatch between the narrative of "purity" communicated and the operational reality revealed to the public. This tension triggered a strategic response from the company in the form of public clarification, transparency of the production process, and repositioning of messages to restore consumer image and trust. This study confirms the importance of narrative coherence and reflexivity in corporate communications, especially in an era of digital openness that demands accountability and consistency between symbolic messages and tangible practices. These findings contribute to the study of crisis communication and brand image restoration strategies, as well as a reference for companies in designing ethical, transparent, and sustainable communication to maintain legitimacy and credibility in the eyes of the public.

Mahdah worship holds a central position in Islamic teachings as a pure form of servitude to Allah SWT. Due to its tauqifi nature, the implementation of mahdah worship must strictly adhere to the provisions of the Sharia without additions or modifications. This study aims to examine and analyze specific fiqh principles that serve as guidelines in the practice of mahdah worship. A qualitative method with a library research approach was employed, through an in-depth review of classical and contemporary literature related to fiqh principles. The findings indicate that principles such as "the default rule in worship is tauqifi," "purity is not limited by time," and "no analogy (qiyas) applies to acts of worship whose rationale is unknown" function to safeguard the authenticity of worship practices from deviation. Understanding these principles is crucial to prevent innovations (bid‘ah) and to ensure that every act of worship remains aligned with Sharia directives. Furthermore, mastery of these principles assists muftis and jurists in issuing consistent and coherent fatwas. The implications of this study highlight the significance of fiqh education in strengthening the community’s awareness of authentic worship and providing a solid framework for evaluating religious practices amidst contemporary socio-religious dynamics.

This study aims to analyze the ibdal rule in Arabic word derivation with an integrative approach between traditional methods and modern linguistics. The ibdal rule, namely the change of one letter into another letter in a word, has long been a concern in classical Arabic studies. The traditional approach views ibdal as part of an effort to maintain the purity and beauty of the Arabic language, based on oral history, analysis of ancient poetry, and readings of the Qur'an. Meanwhile, modern linguistics views ibdal as a rational phonological phenomenon, occurring due to phonetic considerations, ease of articulation, and social dynamics. Through an integrative study, this study found that a comprehensive understanding of ibdal can only be achieved by combining an appreciation of classical Arabic heritage with scientific analysis based on modern phonology and morphology. The results of this study indicate that ibdal is not only linguistic, but also reflects the vitality of the Arabic language in responding to changes in the times. The integration of these two approaches also has an impact on the development of curriculum, teaching methods, and the expansion of Arabic language research space towards a more interdisciplinary direction. This study emphasizes the importance of building a scientific attitude that respects tradition while being open to renewal in Arabic studies. Thus, it is hoped that this research can be a significant contribution to the development of Arabic linguistic studies in a contemporary academic context.
