Abstract

Diabetes mellitus is frequently accompanied by dyslipidemia, which increases cardiovascular risk. Red fruit (Pandanus conoideus Lam.), an indigenous Papuan food rich in tocopherols and carotenoids, may modulate oxidative stress and lipid metabolism. This study investigated the hypolipidemic activity of red fruit extract in diabetic male Wistar rats and evaluated the feasibility of presenting the findings in a supplementary book. A completely randomized laboratory experiment involved 24 rats allocated to six groups: a negative control, simvastatin at 0.72 mg/rat/day, and red fruit extract at 0.12, 0.24, 0.36, or 0.48 mL/rat/day. Diabetes was induced by intravenous alloxan at 70 mg/kg body weight. After fasting blood glucose exceeded 200 mg/dL, the interventions were administered orally for 21 days. Fasting glucose, total cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were measured before induction, after induction, and after treatment. Data were analyzed using one-way analysis of variance followed by Duncan's test (alpha=0.05). The extract contained alpha-tocopherol at 399.10, delta-tocopherol at 250.65, gamma-tocopherol at 108.59, and beta-tocopherol at 32.06 mg/100 g. Treatment significantly affected all final metabolic outcomes (glucose, total cholesterol, triglycerides, and LDL, p<0.001; HDL, p=0.001). The 0.12 mL/rat/day dose produced the greatest reductions in fasting glucose (53.1%), triglycerides (57.4%), and LDL (56.9%), whereas 0.24 mL/rat/day produced the greatest reduction in total cholesterol (40.5%) and best preserved HDL. The highest dose increased fasting glucose. Expert validation and readability scores for the supplementary book were 82.36% and 87.50%, respectively. Red fruit extract demonstrated preclinical hypolipidemic potential, particularly at lower doses; however, the response was nonlinear and cannot be extrapolated as a human therapy without extract standardization, safety assessment, and further investigation.

Abstract

This study evaluates expert-rated feasibility and student perceptions of a project-based learning e-module using Google Sites for History of Physics. A descriptive quantitative product-evaluation design was used to examine product assessments, expert appraisal of the evaluation instruments, lecturer assessments, and a 17-item student response questionnaire. The revised metadata identify 50 eligible students and 47 complete responses, although this figure still requires reconciliation with earlier archive counts. Recalculated unweighted component means were 85.71% for media, 64.80% for content, and 90.00% for language. Expert appraisal of the instruments yielded 90%, 91.25%, and 92.25%; these values are interpreted as content and presentation feasibility judgments rather than comprehensive psychometric validation. Lecturer assessment across 18 indicators averaged 83.33%. Student item scores directly related to the e-module ranged from 85.16% to 90.32%, with the highest score concerning perceived clarity for independent study. Two negatively worded items require reverse scoring (x' = 6 - x), and no empirical reliability coefficient is reported because the individual response matrix was unavailable. The findings identify content alignment and presentation as priorities for revision and describe perceived usability and acceptance without establishing effects on learning outcomes.

Abstract

This research was motivated by the low active participation of students in mathematics learning at SMAS Diponegoro Tumpang, which was still dominated by one-way lecture methods. This study aimed to determine the effect of Baamboozle-based learning media on the mathematics learning interest of grade X students on the material of mean of single and grouped data. A quasi-experimental method with a nonequivalent control group design was used, involving an experimental class (X-D) using Baamboozle and a control class (X-C) using PowerPoint, each analyzed from 25 students determined through cluster random sampling. Data were collected using a validated and reliable 26-item Likert-scale learning interest questionnaire (Cronbach's Alpha = 0.889) and analyzed using Analysis of Covariance (ANCOVA), with post-test scores as the dependent variable and pre-test scores as the covariate, after the normality, homogeneity, and regression-slope-homogeneity assumptions were checked. Descriptively, the mean learning interest of the experimental class increased by 6.00 points (72.60 to 78.60), compared with a 2.32-point increase in the control class (67.48 to 69.80); because the experimental class already scored 5.12 points higher than the control class before treatment, this descriptive gain was interpreted with caution and the pre-test difference was statistically controlled through ANCOVA before any effect was inferred. The ANCOVA showed a significant effect of learning media on post-test learning interest after controlling for pre-test scores, F(1,47) = 16.687, p < 0.001, partial η² = 0.262. These findings tentatively suggest that game-based learning media such as Baamboozle may help foster mathematics learning interest relative to conventional instruction, particularly on statistics topics, although the single-school, two-class design limits how far this conclusion can be generalized.

Abstract

This study aimed to analyze the needs for biology instruction at SMA Muhammadiyah 2 Palembang as a basis for improving instruction on the nervous system topic. A descriptive study using quantitative and qualitative data was conducted with one biology teacher and 31 Grade XI students selected through purposive sampling. Data were collected through questionnaires, semi-structured interviews, and documentation. Questionnaire data were analyzed descriptively using percentages, while interview data were summarized qualitatively. The findings indicate that biology instruction predominantly relies on conventional teaching methods, while the existing student worksheets (LKPD) are not explicitly aligned with a particular learning model syntax. Students reported a preference for learning activities involving discussion, expressing opinions, and evaluation. They also perceived the nervous system topic as difficult because of its complex and abstract concepts. Responses from the teacher and students further indicate a need for learning activities and materials that provide opportunities for active participation and critical thinking. These findings suggest the need for student-centered learning materials that are responsive to students perceived learning needs and the demands of 21st-century learning. The results provide an empirical basis for developing biology learning strategies and materials for the nervous system topic.

Abstract

Tuntutan pembelajaran abad ke-21 menekankan berpikir kritis sebagai keterampilan penting. Pembelajaran kimia perlu mendorong siswa untuk menganalisis informasi, mengevaluasi bukti, dan membuat keputusan yang beralasan. Isu Sosial-Ilmiah (IPM) menyediakan masalah nyata, kontekstual, kompleks, dan kontroversial yang dapat mendorong berpikir kritis melalui penerapan konsep kimia. Studi ini bertujuan untuk mengembangkan tes berpikir kritis kontekstual IPM pada bahan larutan buffer yang memenuhi kriteria yang ditetapkan dan sesuai untuk siswa Fase F di sekolah menengah atas. Studi Penelitian dan Pengembangan (R&D) ini mengikuti tahapan pengembangan instrumen yang diusulkan oleh Liu (2020). Instrumen awal terdiri dari 10 butir esai. Validitas isi dianalisis menggunakan Rasio Validitas Isi (CVR) dan Indeks Validitas Isi (CVI) berdasarkan evaluasi oleh lima Pakar Materi Pelajaran (SME). Pengujian empiris dilakukan dengan siswa di SMA Negeri 3 Bukittinggi menggunakan model Rasch dengan Ministep. Hasil menunjukkan nilai CVR 0,69–0,82 dan CVI keseluruhan 0,70, dikategorikan sangat valid. Analisis Rasch menunjukkan bahwa delapan item sesuai dengan model, dengan reliabilitas item 0,93 dan reliabilitas individu 0,68. Item-item tersebut bervariasi tingkat kesulitannya dari sangat mudah hingga sangat sulit dan dapat membedakan siswa menjadi sekitar tiga kelompok kemampuan. Dua item yang tidak sesuai tidak dipertahankan, sehingga menghasilkan instrumen delapan item yang sesuai untuk menilai pemikiran kritis dalam konteks SSI pada materi larutan penyangga untuk siswa Fase F.

Abstract

Students' chemical literacy regarding the topic of acids and bases remains relatively low, as this subject requires an integrated understanding of macroscopic, microscopic, and symbolic levels. Therefore, this study aimed to design an "Electronic Chemistry Magazine" (E-Chemagz) on acids and bases a valid and practical resource to enhance the chemical literacy of Phase F (high school/Islamic high school) students. The study employed the Educational Design Research (EDR) methodology, following the Plomp model, which resulted in the development of a four prototype (Prototype IV). The prototype development phase adhered to a formative evaluation process, consisting of self-evaluation, expert review, one-to-one evaluation, and small-group evaluation. The validity assessment was conducted by a panel of experts, including three lecturers from the Department of Chemistry at the Faculty of Mathematics and Natural Sciences (FMIPA) of Universitas Negeri Padang (UNP) and two chemistry teachers from a public high school in Padang. The practicality assessment involved two chemistry teachers and nine Phase F students from a public high school in Padang. Data were collected using validity and practicality questionnaires. Validity results were analyzed using Aiken’s V formula, while practicality results were analyzed based on the percentage of the product's practicality achievement scores. The findings indicate that the Aiken’s V values ​​for each aspect ranged from 0.8 to 0.9, falling into the "valid" category. Furthermore, the average practicality scores provided by the teachers and students were 93.17% and 91.15%, respectively, placing the resource in the "highly practical" category. These assessment results demonstrate that the E-Chemagz on acids and bases is both valid and practical for improving the chemical literacy of Phase F high school students. Consequently, this E-Chemagz resource is ready to proceed to an effectiveness test to measure its impact on enhancing the chemical literacy of Phase F students.
