Abstract

Hypertension is a significant health issue with a prevalence of 34.1% in Indonesia, yet many individuals with hypertension do not consistently take medication. Amlodipine, an antihypertensive and antianginal drug belonging to the calcium channel blocker class, is widely used in both generic and branded forms. The differences between these two are often considered when choosing treatment, as generic drugs are more affordable, although their quality is frequently questioned. Generic drugs are often perceived as inferior to branded or innovator drugs. Therefore, research is needed to ensure that the quality of generic drugs is not lower than that of branded products. This study aims to compare the quality of generic and branded amlodipine tablets through weight uniformity testing, content determination, and dissolution testing. A descriptive research method was used. The weight uniformity test was performed by weighing 20 tablets from each sample. The dissolution test was conducted using a paddle-type apparatus (method 2). Content determination was performed using UV-Vis spectrophotometry at a wavelength of 237 nm to determine the amlodipine content in the tablets. Data obtained were analyzed using Microsoft Excel. The results showed that both generic and branded amlodipine tablets met the dissolution test requirements according to the Indonesian Pharmacopoeia (Edition VI), with at least 50% dissolution within 30 minutes as indicated on the label. The dissolution profiles of both generic and branded amlodipine tablets showed similar drug release patterns. However, the dissolution efficiency (DE) for both samples was relatively low, with DE values at the 5-minute mark being 9.52% for the generic tablet and 10.32% for the branded tablet. At the 30-minute mark, the dissolution efficiency for both samples reached approximately 33%.

Abstract

This article examines the epistemology of Islamic education by explaining the role of revelation, reason, experience, and intuition as the main foundations in the formation of knowledge. Unlike Western epistemology, which emphasizes rationality and empirical approaches, Islamic epistemology presents a more holistic perspective because it harmoniously combines spiritual, moral, and intellectual dimensions. This study uses a literature review method, examining various classical and contemporary sources to obtain a more in-depth conceptual overview. The results of the study show that revelation is the highest source of truth, while reason serves as an instrument for understanding reality, and experience and intuition strengthen the process of internalization and application of knowledge in everyday life. This study provides a new perspective by integrating these four sources of knowledge into a single epistemological framework that can be applied in the development of modern learning, thereby emphasizing that today's educational challenges are not only related to technical and methodological aspects but also to strengthening the epistemological foundations that have been neglected. Furthermore, this article highlights the relevance of Islamic epistemology in learning practices through integrated curriculum development, character building, and the use of applicable learning methods. These findings indicate that Islamic epistemology can be an important reference for building a more holistic education that is in line with the needs of the modern era.

Abstract

Antioxidants are compounds that protect the body from the negative effects of unstable molecules that have lost electrons. The Polyalthia longifolia are known to contain compounds such as flavonoids, tannins, and phenols, which have the potential for antioxidant activity. This study employ an experimental methodology to ascertain the chemical composition and assess the efficacy of 70% ethanol extract of Polyalthia longifolia in scavenge free radicals. The extraction process was carried out by maceration for 24 hours over two cycles. The three-color reagent method was used to test for phytochemicals, and the DPPH method was used to test for antioxidant activity using spectrophotometry at a wavelength of 517 nm. The DPPH method was chosen because it is simple, fast, and sensitive; requires only a small amount of sample; and is capable of detecting even weak antioxidants. The IC50 value of the sample was compared to the IC50 value of vitamin C to determine the antioxidant activity of the extract. The study results indicate that the extract of Polyalthia longifolia has very strong antioxidant activity (14,720 µg/mL). This study provides new data on the antioxindant potential of Polyalthia longifolia as a natural source.

Abstract

This study aims to analyze the implementation of character-building flashcards in instilling good moral values in early childhood students at TPQ Al-Hidayah Menjangan. This study employs a qualitative approach using field research. The research subjects consist of TPQ students and teachers who were purposively selected based on their involvement in the character education learning process. Data collection was conducted through observation, direct practice of applying the moral character card media, and documentation. Observation was used to observe the children’s responses and engagement; direct practice was conducted through activities involving the introduction, categorization, and simple evaluation of cards depicting praiseworthy and blameworthy behaviors; while documentation was used to support the field data. Data were analyzed using qualitative descriptive methods through the stages of data reduction, data presentation, and drawing conclusions. The research results indicate that the moral values card medium is effective in enhancing children’s enthusiasm, active engagement, and understanding of akhlakul karimah values. Children can identify and distinguish between virtuous behaviors such as honesty, politeness, and respecting parents, as well as undesirable behaviors such as lying and disobedience. This medium also contributes to cognitive, social, and interpersonal intelligence development through play-based learning. These findings suggest that visual-interactive media are more effective in the internalization of moral values compared to conventional methods. Factors supporting implementation include teachers setting a good example and engaging teaching materials, while the main obstacles are differences in children’s abilities and limited attention spans.

Abstract

Improving the quality of education cannot be separated from the role of teachers as the primary actors in the learning process. However, various issues such as low-quality instruction, suboptimal mastery of technology, and weak application of ethical values, remain challenges in fostering teacher professionalism. This study aims to examine teacher professionalism through the relationship between competencies and professional ethics. This study employs a literature review method with a descriptive qualitative approach, involving the collection and analysis of relevant scientific sources. The findings indicate that competencies and ethics have a complementary relationship in shaping teacher professionalism. Competencies provide the foundational skills for carrying out instructional tasks, while ethics serve as a moral guide for fulfilling those roles responsibly. Without a balance between the two, the educational process risks losing its direction, both in terms of effectiveness and humanistic values. Therefore, teacher professionalism must be developed by strengthening competencies in alignment with the application of ethical values in educational practice. Keywords: Steacher professionalism, competencies, professional ethics, education.

Abstract

This study aims to conceptually examine Assessment as Learning (AaL) as an instrument for fostering student character through a synthesis of various theories and previous research findings. This study focuses on the nature and characteristics of Assessment as Learning, the character values developed through assessment activities, the design of instruments oriented toward character building, as well as the challenges and strategies for its implementation in schools. The study employed a literature review method using a narrative approach. Data were obtained from various scientific articles, books, conference proceedings, and relevant documents, then analyzed using content analysis techniques through a process of information collection, reduction, grouping, interpretation, and synthesis. The results of the study indicate that Assessment as Learning can support the development of students’ character through active engagement in self-assessment, peer assessment, reflection, and the utilization of feedback. This approach contributes to the development of character traits such as academic integrity, responsibility, independence, open-mindedness, social empathy, and self-regulated learning skills. In addition, the implementation of Assessment as Learning requires authentic assessment instruments, transparent evaluation criteria, a culture of continuous reflection, and teachers’ competence in facilitating the assessment process. Thus, Assessment as Learning not only serves as a formative assessment approach but also becomes an effective strategy for integrating the assessment process with the development of students’ character.
