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.

Abstract

This study explores the challenges and economic potential of swamp ecosystems in supporting sustainable regional development in Tapin Regency, South Kalimantan. Employing a descriptive-exploratory qualitative approach, data were obtained through field observations, semi-structured interviews with community members, government officials, and stakeholders, as well as analysis of secondary documents. The research focused on two sub-districts—South Candi Laras and North Candi Laras—which are characterized by extensive swamp areas and active community utilization. The results indicate that the swamp ecosystem in the region plays a vital role in supporting local livelihoods across four main sectors: fisheries, swamp-based agriculture, livestock, and tourism. Inland fisheries, including pond and cage cultivation, show significant annual productivity, especially in North Candi Laras. Agriculture, dominated by seasonal rice farming, contributes substantially to regional food security. Livestock activities, particularly duck and buffalo farming, demonstrate compatibility with swamp conditions and offer opportunities for expansion. Tourism, although still underdeveloped, holds strong potential for nature-based and river tourism. However, various constraints impede optimal development, including poor infrastructure, limited access to markets, environmental degradation, and low community capacity in resource governance. The study highlights that community empowerment, local participation, and context-sensitive policy interventions are critical for enhancing the sustainable management of swamp resources. Furthermore, integrating ecological conservation with economic utilization is essential to transform swamp ecosystems into strategic assets for inclusive and resilient development. This research serves as a foundation for further studies on participatory regional planning and ecosystem-based economic strategies in wetland regions.

Abstract

Competency-based nursing education requires students to master clinical skills critical to workforce readiness; however, challenges persist in the field practicum due to limited structured guidance. This study addresses the lack of research on the effectiveness of structured digital e-mentoring programs in Indonesian clinical settings. The purpose was to evaluate the impact of group e-mentoring on the competence and performance of clinical instructors in supporting nursing student guidance at Nurul Hasanah Hospital, Kutacane. A quantitative quasi-experimental design with a pre- and post-test (without control group) was used. Total sampling based on inclusion criteria resulted in 60 respondents, including clinical instructors and nursing students. Competence was measured using the Mentor Competencies Instrument (MCI), and performance was assessed with the Nurse Mentor Performance Assessment tool. Data analysis employed the Wilcoxon signed-rank test to compare pre- and post-intervention scores. Results demonstrated statistically significant improvements in competence (mean increased from 115.2 to 148.3) and performance (mean increased from 55.8 to 66.2), with p-values of 0.000 and 0.001 respectively, indicating a positive effect of preceptorship and mentorship training integrated within the group e-mentoring program. These findings suggest that structured digital e-mentoring enhances clinical instructors' ability to provide effective student guidance, optimizing clinical education in resource-limited settings.
