Abstract

Monosodium Glutamate (MSG) is a substance that is able to produce free radicals such as ROS (Reactive Oxygen Species), which can cause oxidative stress in the body and damage reproductive organs such as the testes. The purpose of this study was to determine the effect of avocado seed ethanol extract (Persea americana Mill.) on the histology of the testes of mice (Mus musculus L.) induced monosodium glutamate (MSG). This research is an experimental study that was conducted in October 2023 – January 2024 at Biology Laboratory, Faculty of Mathematics and Natural Sciences, Universitas Negeri Padang. The design used is a Complete Randomized Design (CRD) with 4 treatments and 6 repeats. The data obtained were analyzed using the ANOVA test (Analysis of variance) using the SPSS 23 application. The results showed that the administration of avocado seed ethanol extract showed a noticeable effect on the diameter of the testes of male mice exposed to MSG. However, it showed no noticeable influence on testicular weight, seminiferous tubule diameter and Leydig cell count. Ethanol extract avocado seed dose 0.84 mg /g body weight / day (P1) was able to improve the diameter of mice testes that had been induced MSGKeyword: Avocado seed extract, Histology of testis, Mice, MSG

Abstract

Hirschsprung’s disease (HD) has a complex origin involving genetic factors. While HD cases have been documented in Indonesia, the genetic inheritance is unexplored. This study aims to update HD in Indonesia, determine the inheritance pattern through pedigree analysis, and identify the non-genetic factors contributing to HD, including parental demographics and maternal aspects. A cross-sectional survey was conducted with 87 respondents across Indonesia. The results revealed a male-to-female incidence ratio of 1.90:1, with the ultra-short segment being the most common type (75.86%), and familial cases accounted for 8%. Seventeen patients exhibited other congenital abnormalities, with pneumonia, redundant colon, and cardiac defect as the highest cases. Over 70% of the parents were aged 20-35 and had relatively high education and income levels. Notably, nearly half of the mothers experienced food aversion in the first trimester (n=38) and frequently consumed fast or instant food during pregnancy (n=33). The study confirmed that HD follows an autosomal recessive inheritance pattern. These findings emphasize the role of genetic inheritance in incidents of HD, which is valuable for developing early detection strategies and providing genetic counseling for at-risk families. Maternal lifestyle factors may play a role in the development of HD, which needs further investigation.

Abstract

This meta-analysis investigates the effectiveness of the Problem-Based Learning (PBL) model in enhancing students' critical thinking and problem-solving skills in science education. A total of 42 peer-reviewed articles published between 2020 and 2024 were analyzed, covering diverse educational levels and scientific disciplines. The analysis revealed a large average effect size (ES = 0.798; 95% CI: 0.782–0.813), indicating a strong positive impact of PBL. The low standard error (SE = 0.043–0.060) reflects high estimation precision. Statistical tests, including funnel plot symmetry, Trim-and-Fill analysis (p = 0.991), and Egger’s regression test (p = 0.947), confirm the absence of significant publication bias. Moreover, residual heterogeneity was minimal (τ² = 0.000), validating the appropriateness of the fixed-effects model. These findings provide robust empirical evidence that PBL is consistently effective across various contexts in improving students’ 21st-century competencies. The study offers meaningful implications for educators and policymakers in designing science learning strategies that foster higher-order thinking skills.

Abstract

This research is motivated by the development of LKPD (Student Worksheet) for enhancing critical thinking skills of elementary school students. The LKPD used has not yet captured the students' attention. The LKPD has not been able to improve students' learning motivation because it does not align with their learning styles. LKPD serves as teaching material used by teachers to facilitate the delivery of content and achieve learning objectives. This study aims to develop LKPD and assess its validity using the Inquiry model to improve critical thinking skills in Science education about the conservation of natural resources in the 4th-grade class. The type of research used is research and development (R&D), employing the 4-D model. This model consists of four development stages: define, design, development, and dissemination. Based on the results of the validation of LKPD using the Inquiry model to enhance critical thinking skills, the LKPD is deemed feasible for use. The material aspect validation result was 85.41% (valid), the design aspect validation result was 86.53% (valid), and the language aspect validation result was 94.44% (very valid). Therefore, the LKPD using the Inquiry model to improve critical thinking skills is valid.

Abstract

Increasingly developing technology encourages educators to use it in the learning process as a learning medium in order to increase student’s interest in learning. However, currently there are still many who do not optimally use technology-based learning media. The learning media used is monotonous and unable to visualize the material on the excretion system and coordination system in humans. This has an impact on student learning outcomes which are still below the school's Minimum Completion Criteria. Therefore, technology-based learning media such as e-modules in the form of flipbooks are needed. This research aims to produce an Android-based e-module in the form of a flipbook on excretion system and coordination system material that is valid, practical and effective. The type of research used is development research using the Plomp development model which consists of three stages, namely the initial investigation stage, the development stage (prototyping), and the assessment stage. The instruments used were teacher interview guide instrument sheets, student questionnaire sheets, self-evaluation sheets, and e-module validation sheets by experts, as well as e-module practicality assessment sheets in the form of flipbooks filled in by teachers and students. The subjects of this research were class XI high school students. The research object is an Android based e-module in the form of a flipbook on excretion system and coordination system material. The research results show that the Android based e-module in the form of a flipbook obtained very valid criteria validity results with a value of 86.76% and 89.06%, practicality results by teachers and students with very practical criteria with a value of 84.17% and 86.43%. Based on the T test carried out, there is a difference in value between the experimental class and the control class, namely a significance of 0.048 in the excretion system material and 0.003 in the coordination system material. Thus, Android-based e-modules in the form of flipbooks can improve students learning competence.

Abstract

The advancement of molecular biology requires efficient nucleic acid extraction methods to overcome the complexity of biological samples. Fungi associated with avocado plants possess strong cell walls and the presence of host secondary metabolites that may potentially inhibit molecular analyses. This study aimed to isolate and evaluate the quantity and quality of fungal DNA from avocado plants using a combination of mechanical disruption (bead beating) and spin column-based purification. Fungal DNA was isolated using the Quick-DNA™ Fungal/Bacterial Miniprep Kit. Quantification using a NanoDrop spectrophotometer showed that DNA concentrations ranged from 1.7 to 139.1 ng/µL. Most samples yielded DNA concentrations above 50 ng/µL with A260/280 purity ratios ranging from 1.87 to 1.98. Mechanical disruption using beads in a lysis tube facilitated the breakdown of fungal cell walls, while the silica column effectively purified DNA and reduced contaminants that could potentially interfere with analysis. Therefore, the combination of bead beating and spin column methods effectively produced high-quality genomic DNA suitable for further molecular analyses, such as Polymerase Chain Reaction (PCR).
