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 article is about developing mathematics learning materials related to the Indonesian Realistic Mathematics Education (PMRI) approach for teaching the circle topic, with a focus on enhancing sixth-grade students’ conceptual understanding of π (Pi) at MI Ma’arif Pagerwojo. The development followed the ADDIE instructional design model. The research instruments included expert validation sheets, lesson implementation observation sheets, response questionnaires, and achievement tests. Based on expert validation, two validators rated the teaching module at 95.5% and 92.6%, the student worksheet (LKPD) at 91.6% and 94%, and the learning outcome test at 85% and 90% all falling within the "highly valid" category. Observation results of lesson implementation by both teacher and students yielded scores of 90% and 87.5%, respectively, while teacher and student response questionnaires reached 93.7% and 87%. It shows that the developed learning materials are highly practical. The effectiveness also has been proved, as 80% of students met the minimum mastery criterion (KKM), satisfying the criterion for classical completeness. These findings demonstrate that PMRI-based materials effectively facilitate students’ meaningful understanding of π through contextual learning activities. Moreover, the context of this study focused on developing instructional materials at the primary school level remains underexplored in educational development research. Thus, this study may serve as a reference for broader international mathematics education, particularly since PMRI aligns closely with the principles of Realistic Mathematics Education (RME).

Abstract

This study aims to map research trends related to local wisdom in educational science through a bibliometric approach. By analyzing 64 articles obtained from the Scopus database from 2009 to 2024, this study explores publication patterns, cross-country collaborations, dominant keywords, relevant topics, and their implications. The analysis was carried out with the help of the R program application. The results show that publications related to local wisdom have experienced a significant increasing trend from previous years. Indonesia is the main contributor with institutional affiliations such as Padang State University and Surabaya State University. Local wisdom keywords dominate with a strong relationship to science learning and character education. This study is able to provide an overview of the importance of research related to local wisdom related to educational science and provide important insights regarding the integration of local wisdom in science to support the sustainability of local culture while meeting the challenges of global education. Keyword co-analysis reveals that “local wisdom” frequently co-occurs with themes such as science education, character education, and ethnoscience, reflecting efforts to contextualize science learning within cultural frameworks. While the integration of local wisdom presents potential for curriculum development and culturally responsive pedagogy, these implications should be interpreted within the scope of the descriptive bibliometric findings. Further research is recommended to explore practical models and cross-national collaboration strategies. Futre recommendation is for developing a model for integrating local wisdom into STEM and character-based education.

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.

Abstract

Mild to moderate anemia impairs cognitive performance and academic engagement among adolescent girls, yet school-based nutrition programs in Indonesia focus largely on iron and vitamin A. This study evaluated whether a focused 30-day regimen of 20 mg/day zinc could improve both hemoglobin concentration and attention, as measured by the Stroop Color–Word Test, in 30 junior high school girls with baseline hemoglobin < 12 g/dL. Following daily supplementation, mean hemoglobin rose from 10.6 ± 0.5 g/dL to 12.4 ± 0.4 g/dL (Δ = 1.8 g/dL, p < 0.001, Cohen’s d = 3.86), fully eliminating moderate anemia in this cohort. Stroop scores increased from 61.2 ± 5.3 to 75.8 ± 4.6 points (Δ = 14.6, p < 0.001, Cohen’s d = 2.88), with no students remaining in the lowest concentration category post-intervention. These parallel gains reflect zinc’s dual role in enhancing erythropoiesis improving cerebral oxygen delivery—and modulating neurotransmission via NMDA/GABA balance and BDNF upregulation. Effect sizes exceed those typically reported for iron-only or broader micronutrient interventions. Findings support integrating a one-month zinc supplement into Indonesian school-health protocols to rapidly correct anemia and bolster cognitive readiness for learning.
