Abstract

Purpose of the study: This study aims to determine the effects of pork (Sus scrofa domesticus) and beef (Bos taurus) consumption on total cholesterol levels and the histopathological structure of the heart in male ICR mice (Mus musculus). Methodology: This study employed an experimental laboratory design using a Completely Randomized Design (CRD). Fifteen male ICR mice (Mus musculus), aged 2–3 months and weighing 25–30 g, were divided into control, pork-fed (Sus barbatus), and beef-fed (Bos taurus) groups. After 30 days of treatment, blood samples were analyzed for total cholesterol levels, and heart tissues were examined histologically using the Hematoxylin-Eosin (HE) staining method. Data were analyzed statistically using SPSS. Main Findings: Pork consumption increased total cholesterol in male ICR mice to 704 mg/dL. Beef-fed mice showed moderate cholesterol levels (319–321 mg/dL), while the control remained normal (114 mg/dL). Heart weight was highest in the pork group (0.25 g). Histopathology revealed fat cell accumulation only in pork-fed mice, with normal heart structures in both control and beef-fed groups. Novelty/Originality of this study: This study uniquely investigates the direct impact of pork consumption on total cholesterol levels and cardiac histopathology in male ICR mice. It provides new evidence of fat accumulation in heart tissue due to pork intake, contributing to early detection of dietary-induced cardiac risks and expanding current understanding of food-based cardiovascular effects in animal models.

Abstract

Purpose of the study: The aim of this study is to analyze the level of scientific literacy among Grade X students, identify problems during the learning process, and explore factors influencing the effectiveness of Discovery Learning in teaching environmental change topics within the Merdeka Belajar curriculum framework. Methodology: This study used a mixed methods approach with a sequential explanatory design. Data were collected using multiple-choice science literacy tests, interviews with a biology teacher, and documentation. Analysis was conducted with qualitative descriptive methods. Tools included printed tests, interview guides, and documentation logs. Data validation employed triangulation of methods and sources. Main Findings: This study found that the scientific literacy of tenth-grade students at State Senior High School 1 Kota Agung was relatively low, with an average achievement of only 48%. The weakest indicator was the use of scientific evidence (15%), followed by the identification of scientific problems (17%), and the explanation of scientific phenomena (31%). Low literacy was caused by limited learning time, lack of student focus, and a suboptimal learning approach. The Discovery Learning model has the potential to increase students' active participation, conceptual understanding, and critical thinking skills. Novelty/Originality of this study: This study offers a new perspective by integrating the Discovery Learning model with PISA-based scientific literacy indicators in the context of the Merdeka Belajar curriculum. It provides empirical evidence on students’ low scientific literacy in senior high school and identifies key instructional and contextual factors, contributing to more targeted strategies for improving science education in Indonesia.

Abstract

Purpose of the study: The purpose of this study is to investigate the relationship between self-regulated learning (SRL) and students’ critical thinking and scientific communication skills in Biology learning. Specifically, it aims to describe students’ SRL, critical thinking, and communication levels, and analyze how SRL influences both skills in a multicultural bilingual context. Methodology: This study employed an explanatory sequential mixed method. The quantitative phase involved 60 grade XI students at Sekolah Indonesia Davao using total sampling, with data collected through SRL questionnaires, critical thinking tests, and scientific communication rubrics. The qualitative phase involved three students and two teachers via semi-structured interviews. Data were analyzed using descriptive statistics, regression, and Miles–Huberman’s model. Main Findings: The findings showed students’ SRL was moderate to high (M = 3.70), strongest in goal setting and weakest in environmental control. Critical thinking (M = 3.53) and scientific communication (M = 3.51) were moderate, with strengths in problem clarification and claim–evidence–reasoning, respectively. Regression analysis revealed SRL significantly predicted both critical thinking (R² = 0.37) and scientific communication (R² = 0.34). Novelty/Originality of this study: This study offers novel insights by integrating self-regulated learning, critical thinking, and scientific communication within Biology education in an international school context. Unlike previous research limited to two constructs, it empirically shows how SRL simultaneously predicts both skills, thereby advancing understanding of how metacognitive regulation fosters cognitive and communicative competencies in science learning.

Abstract

Purpose of the study: The purpose of this study is to investigate the effect of gamma irradiation treatment on sub-bituminous coal in the bio-solubilization process using Phanerochaete chrysosporium and to characterize the bio-solubilization products of raw and irradiated coal under laboratory conditions. Methodology: This study used sub-bituminous coal from South Sumatra, gamma irradiated with an Irpasena irradiator, and biosolubilized with Phanerochaete chrysosporium. Instruments included a Precision® shaker incubator, Novel® microscope, Hanna® pH meter, Shimadzu® GC-MS, and Shimadzu® UV-Vis spectrophotometer. Data were analyzed statistically using T-test with SPSS version 20 software. Main Findings: The results revealed that raw coal exhibited higher solubilization efficiency compared to irradiated coal, indicated by a greater increase in soluble phenolic (0.95 mg/mL) and aromatic compounds (1.42 mg/mL), as well as higher protein production. GC-MS analysis confirmed that raw coal generated more diverse and abundant metabolites, including phenolic and aromatic derivatives, while irradiated coal produced fewer compounds. Statistical analysis (T-test, p < 0.05) supported the significant differences between treatments. These findings suggest that gamma irradiation does not enhance, and may even inhibit, coal bio-solubilization .. Novelty/Originality of this study: This study provides new evidence that gamma irradiation does not enhance, but rather reduces, the bio-solubilization efficiency of sub-bituminous coal by Phanerochaete chrysosporium. The findings challenge the common assumption about irradiation benefits and contribute to advancing knowledge by highlighting the superior performance of raw coal in producing energy-equivalent products.
