Abstract

Purpose: This study aims to understand how the cultural elements of Surabaya’s Tugu Pahlawan Monument can be used to introduce basic numeracy in primary school, especially concepts related to plane geometry. The goal is to show that cultural landmarks can offer real and relatable examples for young learners. Method: The research was conducted through a qualitative ethnographic approach. The researcher observed the monument directly, spoke with on-site guides and staff who were familiar with its history, and documented various architectural and visual features. All information gathered from notes, photographs, and short interviews was analyzed using the Miles and Huberman framework to identify patterns that relate to mathematical ideas. Findings: The study found that many parts of the monument display clear geometric forms. These include rectangles, squares, circles, triangles, trapezoids, rhombuses, and even a ten-sided figure. Such shapes appear in the floor patterns, plaques, murals, decorative ornaments, museum structures, and the wheels of military displays. Each of these elements can be directly connected to geometry topics taught in primary classrooms. Significance: The findings highlight the potential of local heritage as a meaningful resource for mathematics education. When students see that the shapes they learn in class appear in a monument tied to their own city’s history, mathematical concepts become easier to grasp and more engaging. This approach supports early numeracy while also helping learners build a stronger connection to their cultural environment.

Abstract

Moringa oleifera, known as moringa, is reported to have a high source of natural antioxidants, especially vitamin E. The formulation of purified Moringa leaf extract is needed so that the vitamin E content in it is more maximal. This study aimed to determine the levels of vitamin E in extracts after purification, physical property test of emulgel with variations in extract concentration and vitamin E levels in emulsions. The study was started from the extraction using maceration method with petroleum ether solvent, followed by extract purification using column chromatography with n-hexane solvent. The results of the purified extract were then formulated into emulgel with three concentrations of 3% (F1), 6% (F2) and 9% (F3). Emulgel was then evaluated for physical characteristics (pH, viscosity, adhesion, dispersion and stability). Determination of vitamin E levels was carried out on purified extract samples and on each formula. The results of non-specific standardization of extracts included ash content, acidic insoluble ash content were higher than those of Indonesian Herbal Pharmacopoeia literature and drying losses were lower compared to literature. Specific standardization of extracts was the content of vitamin E in 1.40% PE extract and 8.02% purified extract. In the test of emulgel physical characteristics, an increase in the concentration of the extract caused an increase in viscosity and decreased emulgel dispersion power. Whereas, tthe pH and sticky power remained the same. Storage hds an effect on decreasing the physical characteristics of emulsions especially on adhesion. Increased extracts also caused an increase in the levels of vitamin E in the purified extract of moringa leaf emulgel.

Abstract

Exposure to free radicals and oxidative stress are major factors in various degenerative diseases, such as cardiovascular disease, diabetes, cancer, and neurodegenerative diseases. Therefore, the use of natural antioxidant sources is important to reduce the negative effects of free radicals. This study compares the natural antioxidant potential of black rice, bajakah root, and kebiul seeds, whereas previous studies have only identified the antioxidant potential of a single natural ingredient. This study aims to measure the antioxidant potential, such as total polyphenols, total flavonoids, and antioxidant activity, of these three natural materials using distilled water, 70% ethanol, and 96% ethanol as solvents. The experimental research method involved testing antioxidant activity and measuring total phenolics and flavonoids. The results showed that the 70% ethanol extract of black rice had the highest total polyphenol content at 6.83±0.28 mgGAE/g (0.007±0.00%), the 70% ethanol extract of bajakah wood root had the highest flavonoid content at 8.77±0.02 mgQE/g (0.009±0.00%), and the distilled water extract of kebiul seeds showed the strongest antioxidant activity based on an IC50 value of 5.96 ± 0.01 ppm. This study concluded that black rice has potential as a primary source of phenolics and anthocyanins, while bajakah wood root and kebiul seeds are sources of flavonoids with strong antioxidant activity.

Abstract

This study aims to examine the influence of learning independence and Intelligence Quotient (IQ) on students’ mathematical creative thinking skills. The research employed a quantitative approach with an ex post facto design and was conducted at SMPN 5 Purworejo during the odd semester of the 2024/2025 academic year. The population comprised seventh-grade students, from whom 32 participants were selected through purposive sampling based on the availability of official IQ test results from a professional psychological institution. The research instruments included an essay test measuring creative thinking skills based on four indicators, namely fluency, flexibility, elaboration, and originality; a learning independence questionnaire covering six assessment aspects; and documentation of students’ IQ scores. Data analysis consisted of descriptive statistics, prerequisite testing, and multiple linear regression analysis using SPSS version 25. The results showed that learning independence and IQ significantly affected students’ mathematical creative thinking skills, both partially and simultaneously. Learning independence had a more dominant effect than IQ. Together, both variables explained 92.5% of the variance in students’ mathematical creative thinking skills.

Abstract

Antosianin merupakan pigmen alami yang berperan penting sebagai antioksidan namun stabilitasnya relatif rendah terhadap faktor lingkungan seperti cahaya, pH dan suhu. Upaya untuk meningkatkan stabilitas antosianin dapat dilakukan melalui mekanisme kopigmentasi dengan senyawa polifenol. Penelitian ini bertujuan untuk mengevaluasi pengaruh kopigmentasi antara antosianin beras hitam (Oryza sativa L. indica) dengan polifenol yang diperoleh dari rebusan kacang kedelai (Glycine max L.) terhadap kestabilan warna dan aktivitas antioksidan. Ekstraksi antosianin dilakukan menggunakan pelarut asam sitrat, sedangkan polifenol kacang kedelai diperoleh melalui ekstraksi maserasi dari rebusan kacang kedelai yang diperkaya senyawa fenolik. Kopigmentasi dilakukan dengan variasi rasio perbandingan 1:1, 1:2 dan 1:3, kemudian dianalisis melalui spektrofotometri UV-Vis untuk menentukan pergeseran λmaks, intensitas warna, serta kestabilan pigmen. Hasil penelitian menunjukkan bahwa penambahan polifenol kacang kedelai mampu meningkatkan intensitas warna pada antosianin beras hitam. Selain itu, aktivitas antioksidan menunjukkan peningkatan dibandingkan antosianin tunggal, menandakan adanya sinergi antara kedua senyawa bioaktif. Dengan demikian, kopigmentasi antosianin beras hitam dengan polifenol kacang kedelai berpotensi meningkatkan kestabilan pigmen alami, dengan rasio 1:1 menunjukkan keseimbangan terbaik antara stabilitas warna dan aktivitas antioksidan.

Abstract

Diarrhoea is a widespread gastrointestinal disorder commonly caused by microbial infection, inflammation, or impaired intestinal function. While synthetic antidiarrhoeal drugs are available, their use is often limited by adverse effects and antimicrobial resistance, prompting increasing interest in medicinal plants such as Piper betle (betel leaf). This study systematically reviewed the literature to identify secondary metabolite compounds in Piper betle with antidiarrhoeal potential and to evaluate their biological activities using Radar Chart Analysis (RCA) and Area Under Curve (AUC) methods. A systematic search was performed across PubMed, Scopus, Web of Science, and Google Scholar using predefined keywords. Inclusion criteria comprised studies that investigated Piper betle or its secondary metabolites, reported antidiarrhoeal or related bioactivity, and provided quantitative data suitable for comparison. Studies were excluded if they focused solely on synthetic drugs, were not available in full text, or did not report measurable metabolite data. A total of 35 eligible studies were included after screening 176 records. The findings indicate that flavonoids, polyphenols, tannins, saponins, and catechins in Piper betle contribute to antidiarrhoeal effects through mechanisms that modulate intestinal motility, reduce fluid secretion, activate anti-inflammatory pathways, and exhibit antimicrobial activity. RCA and AUC analyses further demonstrated substantial variability in metabolite composition and antioxidant capacity across studies. Overall, Piper betle exhibits promising therapeutic potential as a natural antidiarrhoeal agent, although further mechanistic and clinical research is warranted.

Abstract

Abstract: The prevalence of type 2 diabetes mellitus (T2DM) has been increasing worldwide and in Indonesia. Documenting locally utilized antidiabetic plants may inform evidence-based phytotherapy. This study mapped antidiabetic medicinal plants in Samigaluh (Menoreh Hills) and prioritized candidates by linking community knowledge with pharmacological data. Semi-structured interviews and observation were conducted between July and August 2025, and involved ten informants selected through purposive and snowball sampling. Quantitative ethnobotanical indices (Use Value, Relative Frequency of Citation, Fidelity Level, Plant Part Value) were calculated, followed by a PubMed-based narrative review. The Zingiberaceae family was predominant (seven species); rhizomes were the most utilized (39.58%), followed by stems (25.00%) and leaves (22.92%). Vernonia amygdalina was prioritized for diabetes-specific consensus (Fidelity Level 100%, Relative Frequency of Citation 0.7), and Curcuma mangga for its high usage and popularity (Use Value 1.3, Relative Frequency of Citation 0.6). Pharmacological evidence indicates that V. amygdalina exhibits antidiabetic effects through the inhibition of α-amylase and α-glucosidase, enhancement of GLUT4, and suppression of gluconeogenesis, supported by its antioxidant and anti-inflammatory properties, while C. mangga demonstrates hypoglycemic activities and β-cell protection, along with anti-inflammatory, antioxidant, and immunostimulant activities as supportive mechanisms. Local knowledge thus aligns with mechanistic findings, supporting a complementary pairing of V. amygdalina and C. mangga for future antidiabetic combinations; further validation through in vitro and in vivo studies is recommended.
