Abstract

Anredera cordifolia (Binahong) is one of the medicinal plants that has been widely used for its properties of inhibiting the growth of microorganisms, decreasing blood uric acid, and healing wounds. This study was conducted to evaluate the acute toxicity effects of ethanolic extract of binahong to support its use as a medicinal plant. Ethanolic extracts of binahong leaves were prepared. Twenty-five white male rats (Rattus norvegicus) were divided into 5 groups and administered with a single dose of Na-CMC suspension or a dose of 300, 600, 1200, or 2400 mg/kg BW of binahong ethanolic leaf extract, respectively. Toxicity symptoms were monitored at three-time intervals: ½-1, 1½-2, and 3-6 hours after the administration. A macroscopic evaluation of the rat’s liver was carried out to identify any lesion. The rat’s liver and whole-body weights were determined to assess the weight reduction. The results showed that there was no dead rat in any of the groups, indicating that no LD50 was identified. Also, there were several toxic effects observed including a decrease in movements, somatic response, insensitivity, and stool consistency. There was no evidence of a lesion on liver macroscopy. However, the weights of rats’ livers increased in tandem with the reduction in their body weights. The findings from this study reveal that single dose of binahong ethanolic extract ranging from 300 to 2400 mg/kg BW are safe, while minimal toxic effects were observed.

Abstract

The use of herbal medicines has become increasingly popular worldwide. Elderly has been associated with higher consumption of many medications, including herbal medicines. However, there is a lack of documentation of medicinal herbs use among Acehnese population. Our study aimed at evaluating the profile of herbals use among the elderly population in a rural area of Aceh Province, Indonesia. A cross-sectional study was conducted from October to November 2021 in Nagan Raya Regency of Aceh. To collect information on the use of herbs, a set of structured questionnaires was utilized. The data were presented in percentage (%). A total of 100 respondents were included comprising 54.0% female and most of the respondents aged between 60–64 years (43.0%). The largest percentage of the participants made their own herbal medicines (45.0%) and used them routinely as a habit (36.0%). About 75.0% of the elderly felt better and almost all of them (96.0%) reported no adverse reaction following herbs consumption. A total of 39 plant species were used by the respondents with Annona muricate L. was the most frequently used medicinal plant (16.0%) and leaves were the most commonly used parts (68.4%). Most of the herbs were prepared through boiling and squeezing (32.6%), and mainly used in the form of a drink (77.3%). Cough treatment with herbs made up 19.3%, followed by hypertension (18.0%), flatulence (7.6%), dyspepsia (5.8%), and fever (5.8%). Our investigation revealed consistency in the use of some medicinal herbs in the present study with published experimental data. However, since elderlies are often considered vulnerable individuals, the practice of herbal self-remedies among this population should be well-monitored.

Abstract

The Minimum Competency Assessment (MCA) is one of the components of the National Assessment (NA) in Indonesia, which aims to measure students' cognitive abilities, including numeracy skills. Students with low numeracy skills can be affected by not being used to working on MCA-type problems. This study aims to develop MCA items on algebra that meet valid, practical, and effective criteria using the Tessmer model, including preliminary, self-evaluation, expert reviews, one-to-one, small group, and field test stages. The subjects in this study were 36 Year 7 students of one junior high school in Banda Aceh, Indonesia. The instruments used were validation sheets, practicality sheets, and student response problemnaires. The findings indicated that 15 MCA problems on algebra have met the validity, practicality, and effectiveness criteria. It shows teachers can use MCA items to train students' numeracy skills. Future researchers are expected to develop multiple problems within a single stimulus with more varied content and context; they will need to consider the novelty of the stimulus in real conditions in the field.

Abstract

Persistent challenges in algebraic learning among Indonesian junior high school students, characterized by performance below minimum mastery criteria, necessitate innovative pedagogical interventions. This study examined the effectiveness of integrating Problem-Based Learning (PBL) with the wizer.me digital platform in enhancing Year 7 students’ algebraic competence within the context of Sustainable Development Goal 12 (sustainable consumption and production). Employing a quantitative one-shot case study design, the research involved 24 randomly selected students from a junior high school in Banda Aceh during the 2024/2025 academic year. Data were collected through a validated post-test instrument comprising four essay questions contextualized within SDG 12 scenarios, assessing conceptual understanding, mathematical modeling, and problem-solving skills. Statistical analyses revealed significant learning outcomes, with students achieving a mean score of 76.33 (SD = 9.78), substantially exceeding minimum mastery criteria (t = 38.224, p < 0.001). Results demonstrate that the synergistic combination of PBL, interactive digital technology, and authentic sustainability contexts effectively facilitates algebraic mastery while cultivating global citizenship awareness. These findings suggest that educators should integrate technology-enhanced problem-based approaches and SDG frameworks into mathematics curriculum to enhance engagement, conceptual understanding, and real-world relevance. Future research should employ larger samples and experimental designs to establish robust causal evidence regarding the scalability and long-term impacts of such interventions.

Abstract

Meningkatnya resistensi antimikroba mendorong eksplorasi sumber agen antimikroba baru dari tanaman obat. Tumbuhan yang tumbuh di lingkungan khusus, seperti daerah geotermal, berpotensi memiliki variasi kandungan fitokimia yang dapat meningkatkan aktivitas biologisnya. Penelitian ini bertujuan untuk mengevaluasi aktivitas antibakteri ekstrak etanol H. formicarum yang berasal dari kawasan geotermal Jaboi terhadap bakteri Methicillin-Resistant Staphylococcus aureus (MRSA)  dan Escherichia coli serta mengidentifikasi kandungan fitokimianya. Uji aktivitas antibakteri dilakukan dengan metode difusi cakram (Kirby–Bauer) pada konsentrasi ekstrak 25%, 50%, dan 75% dengan 3 kali pengulangan. Skrining fitokimia kualitatif menunjukkan adanya alkaloid, flavonoid, tanin, dan triterpenoid. Analisis dengan gas chromatography-mass spectroscopy (GC-MS) menunjukkan adanya resorsinol, 2-metilsiklopentanol, heksana-1,3,4-triol, dan 3,5-dimetil sebagai komponen utama. Ekstrak H. formicarum menunjukkan aktivitas antibakteri terhadap MRSA dengan diameter zona hambat sebesar 9,0–12,0 mm. Analisis two-way ANOVA menunjukkan bahwa aktivitas antibakteri ekstrak secara signifikan lebih rendah dibandingkan dengan kontrol positif (p < 0,001). Tidak terdapat perbedaan yang bermakna antarvariasi konsentrasi ekstrak (p > 0,05). Selain itu, ekstrak tidak menunjukkan aktivitas penghambatan terhadap E. coli, yang mengindikasikan adanya aktivitas antibakteri yang selektif terhadap bakteri Gram positif.
