Domestic violence (DV) is a hidden crime phenomenon with complex criminology, deeply rooted in the interaction between economic pressures and unequal social norms. Financial instability, such as unemployment and poverty, creates profound psychological stress on individuals, especially for perpetrators who fail to fulfill their breadwinner role, which is then expressed through aggressive behavior. Economic crises even causally increase stress, leading to physical or psychological violence. The dominant profile of perpetrators is men with low emotional control who are financially stressed and adhere to patriarchal ideology, while the majority of victims are women (housewives) who are vulnerable due to economic dependence and lack of access to resources, reinforcing the dynamics of economic violence as a systematic means of control. Optimizing response requires an integrated approach: strengthening law enforcement through sensitivity to non-physical violence and guaranteeing the protection of victims' assets, empowering victims economically through training and access to capital to foster independence, and transforming social norms through gender equality campaigns and deconstructing patriarchal culture that considers domestic violence a private matter.

The development of modern education demands that teachers play a broader role beyond merely delivering subject matter, including building professional reputation, credibility, and positive influence on students, colleagues, parents, and society. For Christian Religious Education teachers, personal branding has a deeper dimension because they also serve as role models and ambassadors of Christian values. This study aims to describe the formation of personal branding among Christian Religious Education teachers based on spiritual and theological values, as well as its impact on teaching and student character development. The method used is descriptive qualitative through a literature study of books, journals, notes, and relevant reports, with narrative analysis to illustrate the practices and values that shape teachers’ personal branding. The findings indicate that the personal branding of Christian Religious Education teachers is an integration of professional competence, personal integrity, and Christian values, encompassing authenticity, consistency, professionalism, spiritual and moral role modeling, inspirational and communicative abilities, adaptation to technology, and positive relationships with students and the community. Spiritual and theological values such as Christian love, integrity, humility, patience, justice, service, and commitment to God’s Word form the main foundation that strengthens teachers’ credibility, motivates students, and establishes them as living examples of Christian life. Personal branding for Christian Religious Education teachers is not merely an image or popularity, but a real reflection of faith, character, and daily behavior consistent with Christian teachings, thus supporting effective learning, student character formation, and the teacher’s reputation as an authentic, inspiring, and professional educator.  

The authority of the Religious Courts in Indonesia has undergone substantial transformation since the enactment of the 1974 Marriage Law, which serves as a foundational milestone in harmonizing the national legal system on family matters. Prior to this legislation, the jurisdiction of the Religious Courts was limited and influenced by legal dualism among customary law, Islamic law, and Western civil law inherited from the colonial period. This article examines how the Marriage Law initiated a shift in the structure and legitimacy of the Religious Courts and how their jurisdictional expansion reached a more comprehensive form through Law No. 7 of 1989 on Religious Courts and its subsequent amendments under Law No. 3 of 2006 and Law No. 50 of 2009. Using a normative juridical approach, this study analyzes statutory regulations, academic literature, and Islamic legal doctrines. The findings show that the Marriage Law provided the initial legal foundation for strengthening the Religious Courts' authority in handling family disputes, which was later expanded significantly to include inheritance, wills, grants, endowments (wakaf), alms (zakat), charitable donations (infaq and sadaqah), and Islamic economic matters during the legal reform era. This transformation not only reinforced the institutional structure of the Religious Courts but also improved access to justice for Muslim communities and supported the integration of Islamic law into Indonesia’s national legal framework. Therefore, the development of the Religious Courts’ authority after the Marriage Law reflects the dynamic modernization of the legal system and the harmonization between religious values and the rule of law in Indonesia.

Increasing in energy demand and limited fossil fuel reserves have driven the use of environmentally friendly alternative energy sources. This study aims to analyze the effect of pyrolysis temperature variations on the quality of biopellets made from bagasse and coffee husks. The materials were prepared in a 50:50 ratio with the addition of 15% tapioca flour as a binder. The pyrolysis process was carried out at temperatures of 450°C, 500°C, and 550°C for 120 minutes in oxygen-free conditions. The biochar resulting from pyrolysis was formed into biopellets, which were then tested for proximate composition, calorific value, and combustion rate. The results showed that an increase in pyrolysis temperature had a significant effect on the characteristics of the biopellets. A temperature of 550°C produced the lowest moisture content (8.436%), the highest fixed carbon content (62.191%), the highest calorific value (6293 cal/g), and the highest combustion rate (0.05789 g/sec). Conversely, ash content increased with rising temperature, while volatile matter content decreased. Thus, the best biopellets were obtained at a temperature of 550°C. This study confirms the potential of bagasse and coffee husks as raw materials for biopellets through pyrolysis temperature optimization to support the development of sustainable biomass energy.

Moderate to significant learning gains were shown by N-Gain analysis. The findings prove the effectiveness of interactive learning books in improving students' understanding of the Five Pillars of Islam and providing alternative teaching resources that are more interesting and easier to understand. It is hoped that this publication will serve as a guide for educators in Islamic elementary schools to maximize the teaching of Aqidah Akhlak.

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.

This study aims to analyze the effect of using cassava (Manihot esculenta crantz) as a carbohydrate-based feed ingredient on body weight gain in beef cattle. The review was conducted using a descriptive literature study approach based on sixteen scientific articles discussing the nutritional composition, processing methods, and performance responses of beef cattle fed cassava-based diets. The analysis shows that cassava contains 17.45–88.6% dry matter, 2.4–21.45% crude protein, and 11.35–92.2% nitrogen-free extract, with variations influenced by plant part, processing method, and hydrocyanic acid (HCN) content. Processing techniques such as fermentation and ensiling can reduce HCN levels by more than 70% while increasing crude protein content up to 25%, thereby improving digestibility and feed efficiency. The inclusion of cassava in the form of flour, dried chips, pulp, or fermented peel consistently enhances dry matter intake and average daily gain (ADG) of beef cattle at inclusion levels of 20–50% in the diet. Overall, cassava has strong potential as a locally available, economical, and sustainable feed ingredient to improve beef cattle productivity.

The phenomenon occurring in society regarding deeds of sale and purchase drawn up by land deed officials that contain material defects is certainly contrary to what is stipulated by law. Thus, the research questions are: What are the legal consequences of a material defect in a Deed of Sale and Purchase drawn up by a Land Deed Official? and How does a material defect in a Deed of Sale and Purchase drawn up by a Land Deed Official arise? In this study, the researcher uses Otto Jan Michael's theory of legal certainty and R. Soeroso's theory of legal consequences. The research method used in this study is normative juridical research janis, namely legal research with literature studies. The research approaches used are legislation, conceptual approach, analytical approach and case approach. The technique of collecting legal materials is by identifying and inventorying positive legal rules. Literature, journals and other sources of legal materials. For the analysis technique of legal materials, it is carried out by grammatical interpretation, systematic interpretation, analogy construction and legal refinement construction. The results of this study found the conclusion that the legal consequences of the sale and purchase deed being carried out unilaterally made before PPAT caused the sale and purchase deed to not have legal certainty. Although the sale and purchase deed was made formally by and before PPAT, the legal action contained a material defect, and was canceled by the court, there was also a legal relationship between the legal subjects, the cancellation showed legal certainty, but gave birth to a lawsuit due to unlawful acts, and the legal certainty of the sale and purchase deed made by PPAT contained material defects making PPAT not have binding legal force which resulted in unilateral The sale of land must be done by mutual agreement or known to both parties, in addition to having no legal force, the deed is canceled by the court. Thus, the cancellation of the sale and purchase deed contains a material defect in the court, providing legal certainty for matters that are not in accordance with the applicable provisions of the law.

This study analyzes the implications of the slogan “returning to the Qur’an,” which is frequently understood as a call to rely directly on the Qur’an in addressing religious and social issues while neglecting essential exegetical disciplines such as tafsir, asbāb al-nuzūl, and other authoritative scholarly frameworks. The discussion is reinforced by the findings of Husnul Maab, a postgraduate student at the Institut Ilmu Al-Qur’an (IIQ), whose thesis on the textuality of Qur’anic interpretation and its relationship to religious diversity in Indonesia highlights the serious problems inherent in literalist approaches, particularly in the interpretation of verses related to jihad and politics. This research employs a qualitative library research method, using relevant literature as the primary source of data and analysis, requiring in-depth understanding and critical engagement with the subject matter. The findings indicate that the slogan “returning to the Qur’an” can function as a form of interpretive distortion when it is not accompanied by adequate scholarly competence. Attempts to deepen Qur’anic understanding without integrating the bayānī (textual), burhānī (rational), and ‘irfānī (ethical–spiritual) approaches tend to result in rigid and reductionist interpretations. Such purely textual readings represent an extreme position that may lead to harmful consequences, including the tendency to label others as unbelievers, sinners, or wrongdoers solely due to interpretive differences. Ultimately, religious understanding shaped by reactive and exclusionary interpretations poses a significant threat to religious pluralism and social harmony in Indonesia.

During the coal stockpiling process, the quality of coal may increase or decrease due to direct exposure to open environmental conditions, which can lead to changes in its characteristics. The longer the coal is stored in an open area, the more it undergoes changes caused by rainfall, heat, and air exposure, resulting in an increase in moisture content and ash content, while the calorific value decreases. Therefore, this research was conducted to determine the optimal coal stockpiling duration at the ROM coal stockpile to ensure that the calorific value does not significantly decrease. Coal sampling was carried out every two days from the initial time of stockpiling. After a two-month stockpiling period, the final coal quality results showed a total moisture of 13.89% (ar), inherent moisture of 15.95% (ad), ash content of 4.59% (ad), volatile matter of 40.3% (ad), and fixed carbon of 39.16% (ad). Based on these results, it can be concluded that the recommended storage duration for MCV-HS type coal at the ROM coal stockpile is 154 days. The laboratory analysis results obtained during the research indicate that the longer the coal is stored, the higher the moisture content and ash content become, while the calorific value continues to decrease. This occurs due to water absorption and oxidation reactions that take place during the coal storage period in the ROM coal stockpile.

Coal quality must be controlled from the pit area to the ROM stockpile to ensure compliance with market specifications. However, hauling and stockpiling processes often lead to changes in coal characteristics. This study aims to analyze variations in proximate parameters between coal from Pit B1 and ROM Stockpile Km4 at PT Trisensa Mineral Utama and to identify factors contributing to these changes. The methodology includes field sampling at both locations, sample preparation based on ASTM standards, and laboratory testing of inherent moisture, residual moisture, ash content, volatile matter, and fixed carbon. The results indicate that coal undergoes quality changes after being stored in the stockpile, marked by a decrease in inherent moisture of 2.54% (from 17.64% to 15.10%), a decrease in residual moisture of 1.42% (from 17.17% to 15.75%), a slight reduction in ash content of 0.16%, a decline in volatile matter of 0.28%, and a reduction in fixed carbon of 0.18%. These changes are influenced by field conditions, material contamination during mining, rainfall, coal porosity, and handling activities at the stockpile. The findings highlight the need for improved sampling management, better surface water control, and stricter material handling procedures to minimize coal quality degradation.

Biodiversity is essentially a reflection of the number of species and individuals inhabiting a community, as seen in the Pteridophyta group. These plants, which have evolved to have differentiated roots, stems, and leaves, play an important role in forest systems, primarily as protectors of the soil surface from the effects of erosion, in addition to contributing to the decomposition of organic matter that produces nutrients, and being a major part of the producer chain in the trophic structure. The Jaboi hot spring area, located in the Sukajaya District of Sabang City, exhibits unique ecological characteristics, influenced by the presence of the Jaboi volcano, which gives rise to geothermal phenomena such as fumarole activity, hot steam emissions, and the emergence of high-temperature water flows. This geothermal dynamic directly causes alterations in the physical and chemical conditions of the local soil, thereby shaping habitat characteristics and influencing the existence of vegetation, including ferns. To date, there is little scientific information available on the diversity of ferns in this area. Therefore, this study was conducted to examine and measure the diversity of ferns in the Jaboi hot spring area. The study was conducted in October 2025 using an exploratory survey approach to determine plots and purposive sampling techniques for field data collection. Diversity analysis was based on the Shannon-Wiener index (Ĥ) formula. Based on the identification results, 15 species of ferns from a total of 6 families and 433 individuals were found. The diversity index obtained (Ĥ=2.490171) indicates a moderate level.

This study aims to analyze the quality of coal from the AR_10 borehole in Muara Enim Regency, South Sumatra, based on proximate analysis. The AR_10 borehole has three coal seams (A, B, and C) that were analyzed using the standard ASTM method to determine the coal quality characteristics. The parameters analyzed include total moisture (TM), volatile matter (VM), fixed carbon (FC), ash content (Ash), calorific value (CV), and total sulfur (TS) on an as-received (AR) basis. The analysis results show that seam A has the highest moisture content (19%), seam B exhibits the optimal calorific value (6045 kcal/kg), and seam C has the highest fixed carbon content (42.63%) with the highest sulfur content (0.83%). The correlation between parameters indicates that increases in moisture and ash content negatively affect the calorific value, while an increase in fixed carbon is positively correlated with the calorific value. All three seams fall into the category of low to medium rank coal (subbituminous to high volatile bituminous) with adequate quality for power generation and industrial purposes. This research provides an important contribution to the characterization of Muara Enim Formation coal in South Sumatra for the optimization of local coal resource utilization.

The findings indicate that ChatGPT can offer substantial benefits for Islamic education learning when integrated critically and responsibly, supported by enhanced teacher competencies, clear institutional AI policies, and strong emphasis on ethics and source verification. Thus, ChatGPT holds the potential to serve as a strategic innovation for improving the quality of Islamic Religious Education in the digital era.

Education is a fundamental right that must be fought for by every child in the nation, and throughout its development, it continues to undergo innovations and evaluations toward better quality. One educational model that is growing in Indonesia is the boarding school system, which has its own characteristics, advantages, and challenges. This study aims to describe the social studies (IPS) teachers’ strategies in boarding school–based learning, the implementation of IPS learning within the boarding school environment, and the obstacles faced by IPS teachers at MTs Darul Hikmah. This research employs a qualitative approach with a case study design. The study was conducted at Pondok Modern Darul Hikmah Tulungagung, with seventh-grade students as research subjects. Data collection techniques included observation, interviews, and documentation. The results show several factors that influence the low effectiveness of IPS learning in boarding schools, including the dense institutional activity schedule that reduces students’ learning focus, teachers’ limited mastery of the subject matter and classroom management, and the dual curriculum implemented simultaneously within the institution. Efforts to improve IPS learning effectiveness include enhancing teacher discipline when entering and leaving the classroom, utilizing audio-visual learning media, and connecting learning materials with current issues to make the lessons more relevant and engaging. Furthermore, the study reveals several advantages of boarding school–based education, such as fostering students’ independence, developing social awareness, providing deeper religious instruction, and integrating both general and religious education. Thus, IPS learning in boarding schools has the potential to develop more optimally with the support of appropriate learning strategies and more structured institutional management.

This study aims to analyze the effectiveness of natural resource management, particularly water and soil, in increasing agricultural production in Sampali Village, Percut Sei Tuan District, Deli Serdang Regency. The research approach used was descriptive qualitative through field observations, in-depth interviews with farmers and village officials, and documentation studies from relevant agencies. The results indicate that the irrigation system in Sampali Village is not operating effectively, characterized by shallowing of canals, damaged irrigation walls, and blockages that cause uneven water distribution. This condition has a significant impact on crop yields, with a difference in production between upstream and downstream areas reaching 1.9 tons/ha. Furthermore, soil quality has also declined due to the excessive use of chemical fertilizers, as indicated by a soil pH that tends to be acidic (5.4–6.0), low organic matter content (1.2–1.8%), and decreased soil biological activity. Factors influencing the effectiveness of water and soil management include technical, environmental, socio-economic, and institutional aspects. This study concludes that natural resource management in Sampali Village is still suboptimal, necessitating improvements to irrigation infrastructure, increased use of organic fertilizers, and institutional strengthening and farmer mentoring. These efforts are expected to support sustainable agricultural productivity gains.
