Abstract

Biological facts have been mentioned in the Alquran, which was revealed over 1400 years ago and is proven correct by scientists today. This study focuses on implicit and explicit interpretations of human creation, biological development, and genetic concepts. By using a multidisciplinary approach that combines the maudhu'i method of interpretation, scientific and genetic approaches, as well as textual, intertextual, and contextual interpretation techniques. This study found a connection between Deoxyribo Nucleic Acid (DNA) and the Alquran that is implied in the concept of “nutfah”. The analysis shows that the Alquran mentions various fluids involved in the fertilization process, including sperm, poured fluid, hated fluid, and mixed fluid. This research emphasizes the role of Deoxyribo Nucleic Acid (DNA) as the “master key” that controls human physical and mental functions, and its interaction with the environment in activating certain genes. Deoxyribo Nucleic Acid (DNA) is understood as the “blueprint of life” that stores biological information and plays an important role in the transmission of hereditary traits.

Abstract

This research aims to develop an instrument to improve conceptual understanding of number operation materials owned by prospective teachers at IKIP PGRI Pontianak. This research is a development research. The subjects in this study are students in the third semester of the Mathematics Education Study Program, Faculty of Education, Mathematics and Technology, as many as 20 students who were randomly selected. The main instrument is the researcher himself, while the supporting instruments are the task of number operation problems and interview guidelines. Data analysis is carried out descriptively on all data obtained. The results of the analysis show that the form and type of learning instrument that is suitable for improving students' conceptual ability, especially in the interpretation ability in number operation material, is a multiple-choice sample problem unit. Students' interpretation skills in number operations material are not good because they still have the opportunity to understand and apply the concept of operations on numbers. Learning instruments in the form of units of multiple-choice questions of the second type are practical to be applied with the aim of improving students' conceptual abilities, especially interpretation skills in number operation materials

Abstract

Background: Stroke remains the second leading cause of mortality worldwide and the primary contributor to long-term disability. The stress hyperglycemia, calculated as the fasting blood glucose (FBG)–HbA1c ratio, has been proposed as a marker reflecting acute metabolic imbalance relative to chronic glycemic status, with potential prognostic value in acute ischemic stroke. Objectives: This study aimed to evaluate the association between the FBG–HbA1c ratio and functional independence as well as clinical outcomes in acute ischemic stroke patients. Methods: An analytical observational study employing a cross-sectional design was conducted at Dr. Zainoel Abidin General Hospital. Consecutive sampling was utilized to recruit patients with acute ischemic stroke who fulfilled the inclusion criteria. The FBG–HbA1c ratio was calculated and analyzed in relation to functional independence using the Barthel Index (BI) and clinical outcome using the Modified Rankin Scale (mRS). Pearson Product Moment Correlation test was used to determine the relationship between these variables. Results: A total of 61 patients were included. The FPG–HbA1c ratio demonstrated a significant negative correlation with the Barthel Index (R = –0.43; p = 0.04) and a significant positive correlation with the mRS (R = 0.508; p = 0.03). Conclusion: The FBG–HbA1c ratio showed significant correlations with both functional independence and clinical outcomes, indicating its potential as a simple and reliable prognostic marker. A higher ratio reflects greater stress-induced hyperglycemia, which is associated with poorer neurological function and outcomes in acute ischemic stroke patients

Abstract

Numeracy literacy in Indonesia requires attention, as it remains low, as revealed in the Program for International Student Assessment (PISA) report. A mathematics learning process that can support mathematical abilities, particularly mathematical literacy, must be supported by the characteristics of media skills or tolls that can be adapted to the learning environment. This study aims to develop a mathematics e-comic based on character education to improve elementary school students’ numeracy literacy skills. The research employed a Research and Development (R&D) approach using a simplified Borg & Gall model consisting of seven stages: (1) identifying potential and problems, (2) data collection, (3) product design, (4) design validation, (5) design revision, (6) product trial, and (7) final product revision. The participants were 27 fifth-grade students of SD Negeri 55 Pontianak Barat. Research instruments included expert validation sheets, numeracy literacy tests, and student response questionnaires. The validation results indicated that the e-comic was highly feasible, with scores of 90.67% (content expert) and 93.33% (media expert). The trial results revealed significant improvement in students’ numeracy literacy. The average score for identifying relevant information increased from 64.20 to 92.59, applying whole number operations in real-life problems improved from 62.96 to 93.83, and presenting problem-solving processes with logical reasoning rose from 46.30 to 74.07. The overall average increased from 57.82 to 86.83, reflecting a 50.19% improvement. These findings proves that character education-based e-comic are effective in improving students’ numeracy literacy skills.Rancang Bangun E-Comic Matematika Berbasis Pendidikan Karakter Dalam Meningkatkan Kemampuan Literasi Numerasi Siswa di Sekolah DasarABSTRAKLiterasi numerasi di Indonesia perlu diperhatikan, karena masih rendah seperti yang diungkapkan dalam laporan Program for International Student Assessment (PISA).

Abstract

Selektivitas merupakan karakter elektroda yang paling penting, karena elektroda yang selektif dapat dipakai untuk mengukur analit walaupun terdapat ion pengganggu. Tingkat selektivitas ditentukan oleh nilai tetapan selektivitas potensiometrik. Penelitian mempelajari kinerja elektroda selektif ion La(III) dengan 1-fenil-3-metil-4-benzoil-5-pirazolon (HPMBP) sebagai ionofor, polivinil klorida (PVC) sebagai pendukung, DOP sebagai pemlastis, aliquat-336 klorida sebagai sisi anionik dan THF sebagai pelarut. Faktor Nernst dari elektroda tersebut adalah 51,931 [Cl-] + 11,239 mV/dekade konsentrasi dan koefisen korelasi r = 0,991. Pengukuran tetapan selektivitas elektroda ESI- La(III) dengan cara match potential method (MPM) memberikan hasil bahwa ion-ion logam golongan alkali dan alkali tanah keberadaannya relatif tidak mengganggu pengukuran ion La3+, sementara golongan transisi dalam dan unsur transisi luar (lantanida dan aktinida) dengan keberadaannya sebagai garam nitrat sangat mengganggu pengukuran ion La3+.Kata Kunci: ESI, MPM, potensiometri, tetapan selektivitas
