Abstract

Critical thinking skills are essential for students facing the challenges of the Industrial Revolution 4.0 era. This study aimed to develop and analyze the feasibility of the Flip-Mind interactive module, evaluate the improvement of critical thinking skills, and examine students' responses to its use on temperature and heat materials. This study employed a Research and Development (R&D) method, utilizing the 4D model (Define, Design, Develop, and Disseminate), integrating case-based learning and critical thinking components through interactive HTML5-based features to enhance conceptual understanding. This research employed a pretest-posttest control group design with purposive sampling involving grade XI students from a public senior high school. The validation results indicate that the module is in the "very feasible" category. The improvement in critical thinking skills was indicated by an N-Gain value of 62.7% (moderate category), with an average increase in score of 11%. Students' responses to the module’s use were in the "outstanding" category with a percentage of 82%. These findings suggest that the Flip-Mind interactive module is a practical and feasible alternative to innovative teaching materials for improving critical thinking skills in physics learning. Theoretically, this study enriches the framework of digital learning innovation by demonstrating the integration of case-based and critical thinking-oriented approaches. Practically, the Flip-Mind module offers an effective pedagogical model that can be adapted for interactive and student-centered physics instruction.

Abstract

Breast cancer is the leading cause of death in older women, with more than one million women worldwide dying from this disease yearly. Mammography is a specialized radiological examination that uses low-dose X-rays to detect breast abnormalities, even before visible symptoms such as palpable lumps appear. This study aims to develop an effective mammogram image classification model using the SVM (Support Vector Machine) method with texture feature extraction analysis in histograms and GLCM (Gray-Level Co-Occurrence Matrix). The research involved 20 normal and 20 cancer images, starting with mammogram image preprocessing, then texture feature extraction using histograms and GLCM, and ending with data classification using the SVM method. Test results showed that SVM could classify images with an accuracy of 67.5%, a sensitivity of 33.3%, and a specificity of 70%. Therefore, this research could be a foundation for further developments to enhance mammogram image classification accuracy.

Abstract

Activated carbon derived from coconut shells has great potential as an adsorbent for water purifi-cation due to its high porosity. This study investigates the effect of carbonization temperature on pore formation and adsorption capacity of coconut shell activated carbon. Carbonization was conducted at temperatures rang-ing from 500◦C to 700◦C for 2 hours, followed by chemical activation using 3M KOH solution. The activated carbon was then filtered, washed until neutral pH (± 7), and dried. Characterization was carried out using the BET method to analyze surface area and pore volume, while adsorption capacity was determined using a UV-Vis spectrophotometer with methylene blue as the adsorbate. The results show that increasing the car-bonization temperature enhances pore development, as indicated by higher surface area and pore volume. The highest surface area and pore volume were obtained at 700◦C, reaching 426.692 m2/g and 2.414 cc/g, respec-tively. Correspondingly, the highest adsorption capacity was also observed at 700◦C, with a value of 3957.15 mg/g. These findings suggest that carbonization temperature plays a critical role in optimizing the physical characteristics and adsorption performance of coconut shell-based activated carbon.

Abstract

Big Bang Nucleosynthesis (BBN) is a crucial phase in the universe's evolution, occurring approximately 1 second after the Big Bang. The BBN theory predicts a primordial Helium-4 abundance of about 25%, offering key limits on the number of light particles present at BBN temperatures. The Left-Right Symmetry Model with an Extra Scalar Field is a development of the Standard Model that adds a massive scalar field, which can decay into relativistic particles. This research aims to determine the temperature ratio between the right and left sectors, the mass limit of the massive scalar field consistent with BBN constraints, and the primordial helium abundance. This research is theoretical. The research objectives can be achieved with various methods; the Yukawa Lagrangian and the Scalar Potential are depicted in a Feynman Diagram, which then calculates each sector’s decay rate and temperature changes. The temperature ratio of the right and left sectors when the BBN took place in this model was 0.08-0.09. The BBN constraint imposes a dimensionless bound expressed as the mass ratio of the scalar field in the right sector to that in the left sector is . The abundance of primordial Helium-4 in the left sector is 25%, according to the Standard Model, while primordial Helium-4 in the right industry is 79%-87%. Thus, the Left-Right Symmetry Model with Extra Scalar mode satisfies the constraints of BBN words.

Abstract

Gelodok or mudskipper fish are unique fish that have the ability to live in both aquatic and terrestrial areas. Some Indonesian who live in coastal areas use this fish for consumption. Types of mudskipper that are abundant in Indonesia are from the genera of Boleophtalmus, Periophthalmodon and Periophthalmus, where not all types have been studied for their nutritional content. The aim of this study was to analyze the content of Boleophthalmus boddarti and Periophthalmus variabilis. his study compared the nutritional content of the two types sampled from the Kaliwungu Kendal mangrove ecosystem and the Wedarijaksa Pati mangrove ecosystem. The two types of fish sampled were measured by morphometry which included body length, body width and body weight. Then the fish were analyzed for their nutritional content, namely carbohydrates using the Luff Schroorl test method, protein using the Kjeldahl method, fat using the Soxhlet method, iron using the AAS method, and phosphorus using the spectrophotometer method. The results showed that B. boddarti had a higher protein and iron content than P. variabilis . Meanwhile, P. variabilis had higher carbohydrate, fat and phosphorus content than B. boddarti. The difference was due to different feeding behavior, habitat, and types of food in B.boddarti and P. variabilis.

Abstract

Scientific literacy is essential for both teachers and students to understand natural phenomena and make informed decisions in daily life. However, many teachers face challenges in implementing research-based approaches to enhance scientific literacy in their classrooms. This community service project aimed to provide training on simple research methods for improving scientific literacy to science, mathematics, and geography teachers at MA Salafiyah Kajen Pati. Conducted on November 19, 2025, the training involved 17 teachers and introduced the PISA (Programme for International Student Assessment) framework for scientific literacy, encompassing four key components: science content knowledge, science processes, application contexts, and scientific attitudes. The training emphasized the concept of "everyday science" - recognizing that scientific principles are embedded in common daily activities such as cooking, walking, bathing, and using technology. Teachers were introduced to simple research approaches using everyday contexts to strengthen students' scientific literacy, covering the four aspects of scientific literacy: science as a body of knowledge, as an investigative tool, as a way of thinking, and as interaction between science, technology, environment, and society. The training demonstrated how teachers can utilize familiar daily activities as contexts for developing students' scientific competencies including identifying scientific questions, collecting evidence, drawing conclusions, and communicating findings. Participants engaged in discussions about implementing context-based learning in their subject areas and designing simple research activities that connect scientific concepts to students' lived experiences. The program successfully equipped teachers with frameworks and strategies for conducting simple research to enhance scientific literacy, emphasizing that science education should extend beyond textbooks and laboratories to encompass real-world applications.
