This study aims to analyze the financial soundness and Sharia conformity of Islamic commercial banks using the Risk-Based Bank Rating (RBBR) and Sharia Conformity and Profitability (SCnP) approaches. This research employs a quantitative descriptive method using secondary data derived from financial statements of Bank Syariah Indonesia (BSI), Bank Mega Syariah (BMS), and Bank Muamalat Indonesia (BMI) during the 2021–2025 period. The results indicate that BSI demonstrates the most consistent and superior performance, achieving a very strong financial condition under the RBBR method and maintaining a balanced position in the SCnP model. Meanwhile, BMS shows fluctuating performance, and BMI exhibits high Sharia compliance but relatively low profitability. These findings imply that the integration of financial and Sharia-based performance indicators is essential to provide a more comprehensive and accurate evaluation of Islamic banking performance.

This study aims to analyze the effect of social media use on students' mathematical communication skills. It employs a quantitative approach with a quasi-experimental design (non-equivalent control group design). The sample consisted of 60 eighth-grade students, divided into an experimental group and a control group. The experimental group received social media-assisted mathematics learning, while the control group received traditional instruction. The research instruments included a questionnaire on social media use and a mathematical communication skills test. The questionnaire used a 1-to-5 Likert scale, while the mathematical communication skills test was assessed using a rating scale with scores categorized into three levels: high, medium, and low, defined by intervals of values. Data analysis was performed using simple linear regression and a comparison of means between the two groups. This analysis was conducted using SPSS software. The results showed a significant difference in average mathematical communication skills between the experimental and control groups . Inferential analysis revealed that social media use had a significant effect on students' mathematical communication skills. Furthermore, regression analysis showed that social media use contributed 27.4% to the development of students' mathematical communication skills, with the remainder influenced by other factors external to the study. These results indicate that social media can be a promising pedagogical tool for improving mathematical communication skills through interaction, collaboration, and the interactive exchange of information. Therefore, integrating social media into mathematics learning could create a more communicative and participatory learning environment.

Reconceptualising The Geometry Gap: Theoretical Insights From Van Hiele And Constructivist Perspectives On Triangle Theorem Instruction In South Africa

Shakespear Chiphambo — Fri, 10 Jul 2026 00:00:00 +0000

Geometry forms a fundamental component of secondary school mathematics because it supports the development of spatial reasoning, logical thinking, and deductive proof skills. However, persistent learner difficulties in understanding geometric concepts, particularly triangle theorems, remain a significant concern in many education systems. This conceptual paper examines the factors contributing to the geometry gap in South African schools, with a particular focus on the teaching and learning of triangles and their associated theorems. The paper adopts a conceptual research approach that synthesises recent literature and theoretical perspectives in mathematics education, including the van Hiele theory of geometric thinking, constructivist learning theory and socio-cultural perspectives on learning. Through an integrative analysis of recent scholarship, the paper identifies structural, pedagogical and cognitive factors that collectively influence learners’ geometry learning outcomes. The study further proposes a conceptual framework explaining how these dimensions interact to produce persistent gaps in learners’ geometric reasoning and problem-solving abilities. The interconnected nature of these challenges offers theoretically grounded insights that may inform curriculum development, teacher professional development and instructional innovation aimed at improving geometry education. The findings contribute to ongoing debates on mathematics education equity and provide a foundation for future empirical research on strategies for strengthening geometry instruction in South African schools.

Islamic boarding school governance and Islamic boarding school education from the perspective of Qur'anic ethics with a case study of Al-Khoziny

Fri, 10 Jul 2026 00:00:00 +0000

Islamic boarding schools (pesantren) serve as important institutions for religious education, character formation, and community development in Indonesia. Alongside their educational mission, pesantren are increasingly required to strengthen governance practices to ensure institutional sustainability, educational quality, and public trust. The collapse of a building within the Al-Khoziny Islamic Boarding School complex attracted public attention and raised broader questions regarding institutional governance, risk management, and educational responsibility in pesantren environments. However, previous studies have primarily examined pesantren from leadership, curriculum, and management perspectives, while limited research has explored governance and educational responsibility through a Qur’anic ethical framework. This study aims to analyze Islamic boarding school governance and Islamic boarding school education from the perspective of Qur’anic ethics using the Al-Khoziny case as an institutional reflection. The research employs a qualitative library-based approach combined with a case-based institutional analysis. Data were collected from Qur’anic verses, hadith literature, classical and contemporary tafsir, scholarly publications on Islamic education, and documented information related to the Al-Khoziny case. Data analysis was conducted through a dialectical hermeneutic process consisting of textual interpretation, ethical abstraction, and institutional contextualization. The findings indicate that the Qur’anic principles of al-‘adl (justice), al-amanah (trustworthiness), and al-ihsan (excellence) provide an integrated ethical foundation for strengthening governance and educational practices in pesantren. The Al-Khoziny case highlights the importance of accountability, transparency, institutional supervision, and continuous improvement as essential dimensions of pesantren management. The analysis further demonstrates that Qur’anic ethical values can guide institutional decision-making while supporting the educational mission of fostering responsibility, integrity, and social awareness among students and stakeholders. This study concludes that effective pesantren governance cannot be separated from ethical values embedded in Islamic teachings. The integration of justice, trustworthiness, and excellence contributes to the development of governance systems that support both educational objectives and institutional resilience. The proposed Qur’anic institutional ethics model offers practical guidance for pesantren leaders in strengthening governance, educational quality, stakeholder participation, and long-term institutional sustainability.

Cecep Agus, Astri Dwi Floranti — Sat, 11 Jul 2026 00:00:00 +0000

This research examines whether using AI-generated feedback enhances learners' pragmatic competence and how they engage with intelligent feedback during task-based communication. The study employed an explanatory sequential mixed-methods design with 60 undergraduate EFL students divided into experimental and control groups over eight weeks. Results indicated that learners in the experimental group significantly outperformed learners in the control group in the pragmatically appropriate use of language, politeness strategies and contextually appropriate use of language. Additionally, the analysis showed that immediate and adaptive AI-generated feedback led learners to notice their mistakes, self-repair, and repeat their revisions in cycles. Qualitatively, learners described the AI environment as supportive, flexible, and less anxiety-inducing, which helped them feel more confident in their language use. This study also shows how AI-powered CALL environments can help learners develop L2 pragmatic competence by providing personalized, interactive feedback. Finally, these findings describe the pedagogical possibilities of intelligent feedback systems within a systematically designed instructional approach to support pragmatic instruction in EFL contexts.

Criminal Law Reform for Wildlife Protection Based on Ecological Justice: A Normative Legal Approach in Indonesia

Benny Karya Limantara — Mon, 13 Jul 2026 00:00:00 +0000

Indonesia's exceptional biodiversity is increasingly threatened by wildlife crime, while the legal framework established under Act No. 5 of 1990 has become inadequate for addressing contemporary ecological challenges. Although previous studies have identified weaknesses in wildlife law enforcement, few have translated ecological justice into concrete principles for reforming Indonesian wildlife criminal law. This study examines the urgency of wildlife criminal law reform and develops an ecocentric framework grounded in ecological justice. It employs normative (doctrinal) legal research, using statutory, conceptual, and comparative approaches grounded in legislation, international legal instruments, judicial decisions, scholarly literature, and institutional reports. Legal materials were analysed qualitatively through grammatical, systematic, teleological, evaluative, and prescriptive reasoning. The findings reveal that outdated legal provisions, disproportionate sanctions, fragmented institutions, and limited recognition of ecological integrity as a protected legal interest constrain the current framework. Comparative analysis highlights the importance of aggravated offences, corporate liability, confiscation and restoration orders, proportionate sanctions, and specialised wildlife crime units. The study concludes that Indonesian wildlife criminal law should adopt an ecocentric approach integrating ecological justice into offence structures, sanctions, and institutional mechanisms. This study contributes a normative framework for strengthening Indonesian criminal law reform and biodiversity protection through ecologically oriented wildlife governance.

While formal vocational training is widely explored, the learning mechanisms and Socio-economic impacts of traditional apprenticeships in urban informal vocational communities remain underexplored. This qualitative case study analyses traditional apprenticeship learning patterns and their Socio-economic impacts within a car repair community in Brotojoyo, Semarang. Data were collected from nine participants three experts, three apprentices, and three community leaders via in-depth interviews, observation, and documentation, and then analyzed using the Miles and Huberman interactive model. Findings reveal that the apprenticeship progresses gradually from observation and guided practice to full independence through specific episodes, including negotiation, unloading, workmanship, installation, and finishing. Ultimately, these structured yet informal learning phases significantly enhance apprentices' technical skills and economic welfare, while fostering social solidarity grounded in local wisdom values such as discipline, trust, mutual help, patience, and work responsibility. Theoretically, this study integrates traditional apprenticeship patterns with contextual learning theory. In practice, it offers an alternative, localized model for community empowerment to reduce unemployment and strengthen social capital.

Mathematical communication skills and mathematical representation skills are two important skills in mathematics learning. However, students' mathematical communication skills remain relatively low, so a study is needed to identify the factors that affect them, including mathematical representation ability. This study aims to examine the influence of mathematical representation skills on students' mathematical communication skills in grade VII C at SMP Al Washliyah Sumber. This study uses a quantitative approach with an explanatory correlational design and simple linear regression. The research sample consisted of 31 students selected through purposive sampling. The research instrument is in the form of a description test developed based on indicators of mathematical representation ability and mathematical communication ability, which have met the criteria for validity and reliability. The study's results show that mathematical representation ability has a positive, significant effect on students' mathematical communication skills. These findings suggest that students with good mathematical representation skills tend to have better mathematical communication skills. This research suggests that mathematics learning should facilitate the use of various forms of mathematical representation to improve students' mathematical communication skills.

Legal Protection for Doctors Performing Pregnancy Termination in Anencephaly Cases under Law Number 17 of 2023 on Health

Yusrawati Yusrawati, Dini Dewi Heniarti, A. Harits Nu'man — Tue, 21 Jul 2026 00:00:00 +0000

Legal protection for healthcare professionals remains a significant issue in Indonesia, particularly regarding pregnancy termination in cases of anencephalic fetuses. Although Indonesian law permits abortion on limited grounds, including medical emergencies and pregnancies resulting from rape or other sexual violence, legal uncertainty persists when anencephaly is diagnosed after 14 weeks of gestation. This study analyzes the legal regulation of pregnancy termination in such cases and examines the legal protection available to doctors performing these procedures. Using juridical-normative and empirical-juridical approaches with a descriptive-analytical method, the study combines legal analysis with empirical data collected from 34 informants and respondents, including obstetricians, police officers, healthcare professionals, academics, religious leaders, hospital management, and legal practitioners. The findings indicate that the absence of clear operational regulations for late-detected anencephaly creates uncertainty and increases the risk of criminalization, even when procedures are performed in accordance with medical indications, informed consent, professional standards, and accredited healthcare facilities. Respondents emphasized the need for clearer procedural guidelines, stronger legal guarantees, professional protocols, and coordinated medicolegal mechanisms. The study concludes that pregnancy termination in cases of late-detected anencephaly should not automatically be treated as a criminal act when conducted by competent medical personnel in accordance with medical, ethical, and legal standards. It proposes a lex specialis-based legal protection model to strengthen legal certainty and support future health law reform in Indonesia.

Clinical Pathway Compliance, Length of Stay, and Cost Efficiency among Inpatients at Marsudi Waluyo Hospital

Wed, 22 Jul 2026 00:00:00 +0000

Hospitals are under increasing pressure to improve service quality while maintaining financial sustainability under Indonesia’s National Health Insurance (JKN) reimbursement system. Clinical Pathway (CP) implementation and Length of Stay (LOS) are considered important strategies for improving cost efficiency, yet their financial impact remains inconsistent across healthcare settings. Previous studies have primarily examined the influence of Clinical Pathway implementation on service quality or Length of Stay separately. In contrast, evidence regarding the combined effects of Clinical Pathway compliance and Length of Stay on hospital cost efficiency, particularly in Type D hospitals, remains limited. This study aimed to analyse the effects of Clinical Pathway compliance and Length of Stay on cost efficiency among inpatients at Marsudi Waluyo Hospital, Malang Regency, using Gross Profit Margin (GPM) as the indicator of cost efficiency. A quantitative study with an observational, analytic, and retrospective design was conducted using secondary data from medical records, Clinical Pathway forms, hospital information systems, billing records, and casemix data. The study included 361 inpatient care episodes selected through total sampling. Multiple linear regression was employed to examine the relationships among variables, and bootstrap analysis with 1,000 resamples was applied to enhance the robustness of the estimates. Clinical Pathway compliance significantly affected Gross Profit Margin (β = −0.341, p = 0.029), while Length of Stay also showed a significant negative effect (β = −10.385, p < 0.001). Simultaneously, both variables significantly influenced Gross Profit Margin (F = 30.800, p < 0.001), explaining 14.7% of its variance (R² = 0.147). Length of Stay demonstrated a stronger influence on cost efficiency. This study also contributes empirical evidence on hospital cost efficiency in a Type D hospital and provides practical guidance for hospital managers in developing evidence-based cost-control strategies.
