Abstract

Flash floods are among the most destructive hydrometeorological hazards in tropical highland regions, yet their spatial risks remain poorly quantified in data-scarce environments. This study assessed flash flood risk in Solok Selatan Regency, West Sumatra (Indonesia), by integrating landform and slope classification with the Topographic Wetness Index (TWI) derived from a 30 m DEM. Historical records of 11 flood events between 2010 and 2020 were used for model validation. The analysis revealed that most of the regency is characterized by moderate flash flood risk, while high-risk zones are concentrated in steep fluvial landscapes. Validation against observed flood locations demonstrated a spatial match of 95.2%, confirming the reliability of the model. In addition, the evaluation of hydrological ecosystem service capacity indicated that over 80% of the landscape has only moderate regulatory function, limiting its ability to buffer runoff. These findings highlight the importance of integrating DEM-based hydrological indices with ecosystem assessments to support more effective disaster risk reduction and spatial planning in tropical highland environments.

Abstract

This study aimed to evaluate the effect of mixing watermelon rind (Citrullus lanatus) and kweni mango (Mangifera odorata Griff.) on the color and sensory quality of slice jam while promoting the utilization of fruit-processing by-products. The experiment employed a Completely Randomized Design (CRD) with four treatment ratios of watermelon rind to kweni mango pulp: P1 (20:80), P2 (30:70), P3 (40:60), and P4 (50:50), each replicated three times. Color parameters (L*, a*, b*) were measured using the Color Grab application, and sensory evaluation of color, aroma, taste, and texture was conducted by 25 untrained panelists using a seven-point hedonic scale. Results showed that increasing the proportion of watermelon rind significantly enhanced lightness (L*) and yellowness (b*) while decreasing redness (a*). The sensory test indicated that the P4 formulation achieved the highest overall preference score (5.12), corresponding to a bright golden-yellow color, balanced aroma, and chewy texture. The discussion highlights that the improvement in color and texture is associated with the higher natural pectin content of watermelon rind, which contributes to gel formation and product stability. Moreover, combining kweni mango and watermelon rind demonstrates a viable approach for valorizing agricultural waste into value-added food products. In conclusion, the 50:50 mixture produced the most acceptable slice jam, confirming that watermelon rind can serve as a sustainable, functional ingredient to enhance product quality and support circular-economy practices in tropical fruit processing

Abstract

In the 21st-century education era, scientific literacy has emerged as a crucial competency for addressing global challenges. The integrated STEM (Science, Technology, Engineering, and Mathematics) instructional approach is considered a promising strategy for enhancing students’ mastery of scientific literacy through interdisciplinary integration. However, there remains inconsistency in findings regarding the effectiveness of various STEM models, particularly within the Indonesian educational context. This study aims to examine the effectiveness of integrated STEM learning models on students’ scientific literacy in Indonesia through a meta-analytic approach. A total of 10 peer-reviewed articles published between 2021 and 2025 were analyzed using the Comprehensive Meta-Analysis (CMA) software version 4. The results indicate that STEM-based learning demonstrates a high overall effect size of 0.995 (categorized as large, p < 0.001). Among the models examined, Project-Based Learning (PjBL) emerged as the most effective and consistent model, while Problem-Based Learning (PBL) exhibited a relatively smaller effect size. Other models, such as Blended Learning, Inquiry Learning, and RADEC, also showed very high effectiveness; however, these findings require further empirical validation through additional studies. Moderator analysis revealed significant differences across the models (Qb = 7.85; p = 0.005), suggesting that the type of instructional model moderates the effectiveness of the STEM approach. These findings support the development of more evidence-based and contextually relevant science teaching strategies tailored to the Indonesian educational landscape.

Abstract

This study aims to identify research trends, dominant science topics, and technological platforms used in educational games designed to improve students’ learning motivation in science learning from 2020 to 2025. A Systematic Literature Review (SLR) was conducted using the PRISMA framework. Scientific articles were retrieved from the Google Scholar database and screened using the Publish or Perish software based on predefined inclusion and exclusion criteria. Six articles met the final eligibility requirements. The results show that publication trends during this five-year period were unstable, with increases in 2021 and 2024, a decline in 2022, and an absence of publications in 2025 due to ongoing review and publication processes. Biology and environmental science were the most frequently used topics in educational game development, representing 50% of the reviewed studies, while physics appeared only once due to its abstract nature. Wordwall was the most widely used platform, followed by Educandy, QuizWhizzer, RPG Maker, and digital adaptations of the Talking Stick Game. Overall, all reviewed studies consistently reported that educational games had a positive impact on students’ learning motivation. These findings highlight the pedagogical relevance of game-based learning and suggest the need for further exploration of underrepresented science topics and more diverse game development technologies.

Abstract

Determinants are conventionally defined only for square matrices, which leaves the theoretical discussion of rectangular matrices relatively undeveloped. This study aims to extend determinant theory by introducing a generalized form of the cofactor expansion applicable to non-square matrices. The method employed in this research is a theoretical–analytical approach that begins with identifying fundamental determinant axioms and proceeds with the construction of a recursive cofactor expansion for   matrices with . Worked examples are used to demonstrate the linearity, antisymmetry under row interchange, and reduction consistency of the proposed formulation when applied to square matrices. The findings indicate that the generalized expansion preserves essential algebraic properties and shows compatibility with established rectangular determinant definitions, including the Radić determinant. Overall, this study provides a coherent theoretical foundation for the generalized determinant of rectangular matrices and contributes to broader applications of determinant-based analysis in linear algebra

Abstract

Periodontal disease is more prevalent and severe in patients with type 2 diabetes mellitus. This study aimed to describe periodontal status and examine its association with gender and age among diabetic patients enrolled in the Prolanis program. A cross-sectional analytical survey was conducted on all 65 Prolanis participants with confirmed type 2 diabetes mellitus at Banjarbaru Selatan Community Health Center, Indonesia. Periodontal status was assessed using the Community Periodontal Index of Treatment Needs (CPITN). Severity was dichotomized as not severe (score 0–2) and severe (score 3–4). Associations with gender and age groups were tested using chi-square tests (α = 0.05). Participants were predominantly female (84.6%) with a mean age of 58 years. Severe periodontitis (pocket ≥4 mm) was found in 63.1% of patients. No significant association was observed between periodontal disease severity and gender (p = 0.733) or age group (p = 0.114). A high burden of moderate-to-severe periodontitis exists among diabetic patients in the Prolanis program, irrespective of gender or age. Regular periodontal screening and integrated diabetes–oral health management are strongly recommended.

Abstract

Indonesia, a megadiverse nation, possesses extraordinary biological wealth, including a vast array of medicinal plants, diverse fauna, and unique microbial ecosystems. This rich biodiversity, however, faces severe threats from habitat loss and climate change, underscoring the urgent need for its documentation and scientific utilization, particularly in emerging fields such as epigenetics. Epigenetics, which involves heritable changes in gene expression without altering the DNA sequence, is fundamental to understanding biological processes and disease.  While foundational epigenetic discoveries often originate from microorganisms, Indonesia's extensive microbial and plant diversity, including endemic species, remains largely unexplored regarding its epigenetic potential. This review highlights Indonesia’s biodiversity, including representative species, as a promising source of novel model organisms for epigenetic research and bioactive metabolites with significant medical potential, which may possess epigenetic-modulating properties as natural ‘epidrugs’ inspired by traditional Indonesian herbal medicine known as jamu. Bridging biodiversity research with molecular epigenetics offers a powerful framework for identifying new epigenetic mechanisms, regulators, and natural compounds, opening new frontiers in personalized medicine and disease prevention within Indonesia's unique biological and cultural landscape.
