Predictive model of declining glomerular filtration rate in type 2 diabetes mellitus with poorly glycemic control: Integration of RAAS and TGFB polymorphisms with clinical risk factors in the Jambi Malay population
No full textBackground: Diabetic kidney disease (DKD) is a major complication of type 2 diabetes mellitus (T2DM) and a leading cause of end-stage renal disease worldwide. Despite optimal glycemic and blood pressure control, many patients experience renal decline, suggesting a role for genetic factors. Objective: To develop a predictive model integrating clinical and genetic parameters to identify individuals at risk of declining glomerular filtration rate (GFR) among Malay Jambi patients with poorly controlled T2DM. Methods: A cross-sectional study of 62 patients was conducted using ACE rs4343 and TGFB1 rs1800470 genotyping by Tetra-ARMS PCR. Declining renal function was defined as eGFR <60 mL/min/1.73 m² (KDIGO 2024). Logistic regression and ROC analyses assessed model performance. Results: Older age and higher blood pressure were associated with reduced GFR. The TGFB1 rs1800470 TT and ACE rs4343 AG genotypes significantly increased the risk of renal decline (adjusted OR 7.79 and 5.98, respectively; p < 0.05). The integrated clinical–genetic model achieved the highest discrimination (AUC = 0.859; sensitivity 78.9%; specificity 88.4%). Conclusion: Integrating ACE and TGFB1 genotypes with clinical factors enhances DKD risk prediction and supports early genotype-informed interventions. This approach strengthens population-specific precision nephrology in Indonesia and provides a foundation for future polygenic risk model development

No full textBackground: Jackfruit (Artocarpus integer) peel is an agricultural waste with potential as a source of bioactive compounds. Objective: This study aims to evaluate the potential antioxidant activity of cempedak fruit peel extract using a 96% ethanol solvent. The extract, tested as fraction F3P, is believed to contain phenolic and flavonoid compounds that act as free radical scavengers. Extraction was performed using the maceration method. Methods: Antioxidant activity was tested in vitro using the DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging method at various concentrations, ranging from 20 ppm to 100 ppm. Based on the percentage inhibition data obtained, the IC50 (Inhibitory Concentration 50%) value was calculated through logarithmic/linear regression analysis. Results: The calculation results show that the 96% ethanol extract of cempedak fruit peel (fraction F3P) has an IC50 value of 8.872 ppm. This IC50 value, which is below 50 ppm, indicates that the extract has very strong antioxidant activity. The active compounds within it can reduce 50% of DPPH free radicals at very low concentrations. Conclusion: This study concludes that the 96% ethanol extract of cempedak fruit peel is a highly potent and valuable source of natural antioxidants. Utilizing jackfruit peel waste can be a solution for developing functional food products or health supplements

Digital literacy in english language education: Bridging teachers’ competence and learners’ needs
No full textDigital literacy has become indispensable in English language education, particularly in bridging teacher competence with learner needs in a rapidly evolving digital era. This study employed a Systematic Literature Review (SLR) of peer-reviewed works published between 2020 and 2025, focusing on digital literacy and digital competence in ELT/EFL contexts. Key sources include micro-course interventions for teacher development in higher education (Discover Education, 2025), empirical analyses of EFL teachers’ digital literacy in Chinese universities (Feng & Sumettikoon, 2024), and case studies of Indonesian pre-service teachers’ digital practices (Nur, Nur & Sunra, 2023). The findings reveal that while teachers generally possess basic digital tool knowledge, they often lack the pedagogical integration skills and confidence needed to foster critical digital engagement. Learners, meanwhile, demonstrate familiarity with everyday technologies but require structured support for academic digital tasks. Thematic synthesis highlights persistent barriers, including limited training opportunities, inadequate infrastructure, and insufficient institutional support. Opportunities identified involve the adoption of micro-courses for continuous professional development and practice-oriented modules that enhance both pedagogy and learner participation. This review addresses the gap in understanding how teacher digital competence and learner digital literacy intersect in ELT/EFL contexts, offering a unified perspective to inform teacher education and policy. This paper concludes that strengthening teacher competence alongside addressing learners’ digital literacy needs is crucial to ensuring digital literacy functions as a transformative element in ELT rather than as a superficial supplement. These findings provide practical insights for teacher training programs seeking to strengthen digital literacy in ELT
Academic supervision, altruistic leadership, trust, and teacher enjoyment: Analyzing their influence on teacher performance in Bungo Regency
No full textThis study examines the influence of academic supervision and altruistic leadership on teacher performance through the mediating roles of teacher enjoyment and trust in school leaders among high school teachers in Bungo Regency, Indonesia. Grounded in growing evidence that leadership behaviors, supervisory quality, and teachers’ emotional experiences shape professional performance, this research explores how these variables interact within a contemporary educational context. Using a quantitative causal survey design, data were collected through an online questionnaire distributed to 503 teachers across 19 public high schools, with 98 valid responses analyzed using SEM-PLS. The findings indicate that academic supervision does not directly improve teacher performance, but significantly increases trust in school leaders (β = 0.610, p < 0.001). Altruistic leadership also does not directly predict performance; however, it significantly enhances teacher enjoyment (β = 0.315, p = 0.035). Teacher enjoyment emerges as the strongest predictor of teacher performance (β = 0.469, p < 0.001), highlighting the dominant role of positive emotional experiences in shaping instructional effectiveness. Several indirect effects particularly those involving enjoyment as a mediator approach significance, suggesting complex psychological pathways connecting leadership and performance. The study underscores the importance of instructional supervision that is developmental rather than administrative, leadership practices rooted in empathy and moral concern, and school initiatives that prioritize teacher well-being. These findings highlight the need for holistic leadership and supervision approaches that integrate emotional, relational, and professional dimensions to enhance teacher performance and educational quality
