Abstract

This study investigates the relationship between nutritional knowledge, nutritional status, and academic achievement among junior high school students. Nutrition plays a vital role in cognitive performance, influencing concentration, memory, and energy levels. A cross-sectional correlational study was conducted at SMP Negeri 14 Palu, Central Sulawesi, involving 60 students across grades VII to IX. Data were collected using a structured questionnaire, anthropometric measurements, and academic performance records. Bivariate analysis using the Gamma correlation test revealed a statistically significant positive relationship between nutritional knowledge and academic achievement (Gamma = 0.515; p = 0.003). Conversely, a significant negative correlation was observed between nutritional status and academic performance (Gamma = –0.543; p = 0.040). These findings underscore the importance of structured nutrition education in supporting academic outcomes, while also highlighting the complex, non-linear relationship between physical health indicators and cognitive performance.

Abstract

Various studies on relational thinking have been conducted, but none have explicitly examined students’ learning obstacles from the ontogenetic, epistemological, and didactical perspectives. This study aims to identify and describe students’ learning obstacles in relational thinking within arithmetic, algebra, and linear equations in one variable. This study employs a qualitative approach guided by Miles and Huberman’s framework, which involves data collection, data reduction, data display, and drawing and verifying conclusions. The study used tests and interviews to gather information. Data were collected in August 2023 from 32 students of 8th grade at SMPN 17 Tangerang Selatan. Analysis revealed that students encountered ontogenetic, didactical, and epistemological obstacles when solving mathematics problems requiring relational thinking. The ontogenetic obstacle manifested as a lack of confidence in their own mathematical abilities. The didactical obstacle arose from the use of instructional materials and learning designs that did not facilitate development of relational thinking ability. The epistemological obstacle was evident in students’ failure to understand arithmetic and algebraic operation rules, inability to construct mathematical models from everyday situations, and misinterpretation of the equals sign (“=”) as an operational command rather than a symbol of equality. Teachers therefore require additional learning resources to reinforce students’ understanding of the concept of equality. Future research should focus on developing and evaluating instructional designs specifically aimed at enhancing students’ relational thinking ability.

Abstract

In this study, we analyzed the effects of different concentrations of Moringa oleifera leaf flour on the carbohydrate, protein, and fat content of wet noodles. We conducted an experimental study using a Completely Randomized Design (CRD) and analyzed the data through ANOVA and LSD tests using SPSS 21 software. The results showed that fortifying wet noodles with Moringa leaf flour significantly altered their macronutrient composition. The carbohydrate content decreased from 28.286% in treatment 2 to 27.350% in treatment 3 and 25.677% in treatment 4. In contrast, the protein content increased from 5.289% in treatment 2 to 5.905% in treatment 3 and 6.345% in treatment 4. Similarly, the fat content rose from 0.439% in treatment 2 to 0.554% in treatment 3 and 0.645% in treatment 4. These findings suggest that increasing concentrations of Moringa leaf flour can improve the nutritional profile of wet noodles, particularly by enhancing their protein and fat content while reducing carbohydrate levels.

Abstract

Mathematical literacy is essential for applying mathematical concepts to real-life problems, yet its development is often hindered by psychological factors such as anxiety and resilience. Mathematics anxiety negatively affects students' cognitive and problem-solving abilities, while resilience supports emotional regulation and sustained learning. This study aims to examine the combined influence of mathematics anxiety and resilience on students’ mathematical literacy. The research method used was qualitative with a phenomenological approach. The data collection process, including validity, reliability, and subject selection, was conducted using the Winstep application. Three subjects were selected according to three levels of mathematical literacy. The data analysis process involved administering tests, questionnaires, and interviews, with the test questions focusing on probability material. The results of the study indicate that students with high anxiety levels and low resilience have lower mathematics literacy scores. They are unable to complete all the ability indicators. Similarly, students with moderate anxiety and moderate resilience also showed low literacy scores. They were able to complete questions on the comprehension and representation indicators.

Abstract

Mathematics is a supporting science for other branches of science as a medium for communicating mathematical problem solving. One of the abilities that must be possessed by students is the ability to communicate in trigonometry material. In this research, only 36.7% of students correctly identified the transformation of trigonometric function graphs in question number 9. However, there were some students whose explanations were not precise because their understanding of the material was not correct. The purpose of this study is to analyze the mathematical communication skills of grade X MA students in the material of trigonometric function graphs. In this research, a qualitative research type with a descriptive approach is used. The test of mathematical communication ability in writing is in the form of a test that is done independently and tested on 6 students with a group of 2 high ability students, 2 medium ability students, and 2 ability students with the need for further guidance. While the test of mathematical communication skills orally answered together through the interview method. The significance of this research is the students become more focused in learning because students are instructed to do activities by shifting the slider so that the intended graph is formed according to the instructions of the given problem. The conclusion drawn from the results of the research conducted is that mathematical communication in the material of trigonometric function graphs is relatively low, both in writing and orally. This is based on the percentage in the analysis test of mathematical communication skills in writing where students answered 10 out of 18 items had below 50% incorrect written response rates, compared to 8 other items that students could answer correctly with a score above 50%, while in the oral mathematical communication ability analysis test there are still misconceptions in every question asked. This is based on this research data that some students still answer the items incorrectly.

Abstract

The global demand for renewable energy is increasing along with the awareness of the environmental impact of using fossil fuels. This research investigates the application of the Routh-Hurwitz Procedure in enhancing the stability and operational efficiency of grid-connected renewable energy systems through systematic controller tuning and pole placement analysis. This study employed a Systematic Literature Review (SLR) based on PRISMA guidelines. Based on a literature review analysis of 27 articles from 2020-2025, it confirms that the Routh-Hurwitz method improves system stability by ensuring all poles are in the left-hand plane of the complex domain. The findings show that integrating Routh-based tuning with hybrid controllers such as PSO and ANN can reduce frequency oscillations, voltage and frequency stability are improved, and total harmonic distortion (THD) is reduced by as much as 1.967% and enhances frequency control within ±0.1 Hz. Simulation results corroborate these conclusions and confirm the method's efficacy in actual PV and VSG-based systems. The Routh-Hurwitz criterion provides measurable enhancements in controller design for renewable energy integration and guarantees system stability by methodically assessing pole placement in the complex domain.

Abstract

This study aims to isolate and identify terpenoid compounds from kluwih leaves (Artocarpus camansi). Extraction was done using methanol solvent, followed by n-hexane fractionation, which produced a concentrated blackish green extract. Compounds were separated through column chromatography with silica gel as the stationary phase and n-hexane as the mobile phase, and a mixture of n-hexane: ethyl acetate, producing eight fractions. The third fraction, obtained as green crystals, exhibited a positive reaction to the Liebermann-Burchard reagent, a specific test for the presence of terpenoid compounds. The observed colour change indicated the presence of terpenoids, making this fraction a promising candidate for isolation and detailed analysis. After recrystallisation, white needle-shaped crystals were obtained with a melting point of 141–142.8°C. Purity testing using thin layer chromatography (TLC) showed a single spot in various eluents, indicating that the isolated compound was pure. Further characterisation using UV spectroscopy showed maximum absorption at 210.2 nm, while IR spectroscopy showed the presence of OH, methyl, and non-conjugated C=C double bonds. Based on these data, the isolated compounds can be identified as terpenoid compounds. This study provides a basis for further studies on the structure and biological activity of kluwih leaves.

Abstract

Heart disease is one of the leading causes of mortality in Indonesia, yet early detection remains a challenge due to limitations in data and suboptimal classification methods. This study aims to improve the accuracy of heart disease prediction by integrating the Naïve Bayes algorithm with Particle Swarm Optimization (PSO) for feature selection. A dataset of 303 patient records was processed using RapidMiner across three configurations: Naïve Bayes with split validation (80:20), Naïve Bayes with 10-fold cross-validation, and Naïve Bayes with PSO-based feature selection. The results showed that incorporating PSO increased accuracy from 87.60% to 89.26%, along with improvements in precision and recall, while maintaining a high AUC value (0.933). These findings demonstrate that PSO effectively identifies the most relevant features and enhances the performance of heart disease prediction models. The study also underscores the importance of validation methods and model interpretability in the application of artificial intelligence in healthcare.
