Abstract

This study addresses the instability, off-flavors, and variable quality that limit the use of fish oil as an omega-3 source, particularly from milkfish (Chanos chanos). The research aims to produce omega-3-rich milkfish oil that meets international quality standards and is suitable for microencapsulation. Fresh milkfish was processed using wet rendering at four temperatures (70, 80, 90, and 100°C) and three heating times (30, 40, and 60 min). The crude oil was then refined by alkali neutralization with different NaOH concentrations. Oil yield and oxidative quality parameters—peroxide value, p-anisidine value, total oxidation (TOTOX), and acid value—were measured and analyzed using factorial ANOVA. The highest yield (0.29%) was obtained at 100°C for 60 min. Peroxide and anisidine values (3.44 and 11.75 meq/kg) and TOTOX (<20 meq/kg) complied with International Fish Oil Standards, whereas acid values (2.43–2.68 mg KOH/g) exceeded the limit at prolonged high-temperature extraction. These results indicate that higher temperatures increase oil recovery but promote hydrolytic degradation. Careful optimization of time and temperature is therefore required to obtain stable, high-quality omega-3 milkfish oil for further microencapsulation and application in health-oriented food products.

Abstract

This research review explores the role of artificial intelligence (AI) in personalizing mathematics and science education to enhance student learning experiences and outcomes. The study synthesizes current research to examine how AI-driven technologies—such as adaptive learning systems, intelligent tutoring, and real-time feedback mechanisms—support individualized instruction aligned with students’ learning styles, paces, and cognitive needs. Findings indicate that AI significantly improves engagement, conceptual understanding, and problem-solving skills by leveraging data analytics and machine learning to deliver tailored content. These systems are grounded in established educational theories, including Mastery Learning and the Zone of Proximal Development. However, challenges remain, including unequal access to technology, algorithmic bias, data privacy concerns, and limited teacher preparedness, which hinder equitable implementation. The review also identifies gaps in longitudinal and context-specific research, particularly in under-resourced educational settings. The study concludes that while AI holds transformative potential for STEM education, its effective integration requires ethical design, inclusive policies, teacher training, and pedagogical alignment. For sustainable impact, AI should be implemented as a supportive tool within human-centered educational frameworks rather than a standalone solution.

Abstract

This study aims to analyze and provide an overview of the micsconceptions experienced by students, the diagnostic instruments used and their causes in chemistry learning. The research method used was literature review. The research data consisted of 20 relevant national and international articles in the range of 2019-2025. The articles selected have similar topics of discussion regarding misconception analysis in chemistry learning. The results showed that the research on misconceptions in chemistry learning mostly frequently found in the concept of acid-base and salt hydrolysis, reaction rates and chemical equilibrium, thermochemistry, and chemical bonding. The diagnostic instruments used include two-tier tests, three-tier tests, four-tier tests, five-tier tests, questionnaires, multiple-choice questions and interviews. Factors causing misconceptions are due to internal and external factors. Internal factors include the discrepancy between students' preconceptions and experts' knowledge concepts, while external factors include learning methods and teaching materials used by teachers. In addition, there is no significant difference between the instrument used and the misconceptions found across countries. So that the trend of misconception research is a study that deserves to continue to be developed and researched

Abstract

Indonesia, as the world's largest nickel producer, has vast ultramafic areas that have the potential to become habitats for nickel hyperaccumulator plants (Ni). This study aimed to explore and analyze nickel hyperaccumulator plants in the mining area of CV. Unaaha Bakti Persada, North Konawe Regency, Southeast Sulawesi, Indonesia. The research was conducted from June to November 2023 using the exploration method at three observation stations, each consisting of three plots. The research stages carried out include exploration, plant collection and identification, and analysis of Ni content in soil as well as plant tissue using Atomic Absorption Spectrophotometry (AAS). A total of 32 plant species were found, which was dominated by Pteridium aquilinum ferns at Stations I and III and Scleria lithosperma grasses at Station II. The Ni content of the soil was very high (5,458.32–5,938.41 mg/kg) and far above the normal threshold. Several species showed high Ni accumulation capacity, with the most of six were Sarcotheca celebica, Knema metanensis, Pluchea carolinensis, Gymnostoma sumatrana, and Justicia gendarussa. The post mining sites were categorized as marginal due to heavy metal toxicity (Ni, Co, Cr), and therefore, only tolerant plants can survive. Sarcotheca celebica had the highest BCF value (0.1421) and was classified as a moderate accumulator. All the six species has the potential to be used for phytoremediation, phytomining and reclamation of post mining areas in Southeast Sulawesi.

Abstract

The integration of digital technology with a contextual learning approach is a strategic solution to improve conceptual understanding and reduce misconceptions in physics learning. This study aims to analyze the need for developing website-based learning media that integrates the concept of edupark as a contextual approach. The method used in this needs analysis employs the EDUPARK development model, limited to the EDU stage. Data collection instruments include the EDUPARK potential format, physics concept observation sheets at the EDUPARK, questionnaires, interview sheets, and curriculum reviews at SMAN 4 Padang. The results of the Edupark Finding stage identified the Lumindai Stone Forest tourist attraction. The Direct Observation stage revealed that the physics concepts present at the edupark location include gravity and equilibrium, thermodynamics, sound and light waves, and energy. Finally, the Understanding of Teacher, Students, and Curriculum Characteristics stage revealed that students experienced high levels of misconceptions due to the lack of interactive and contextual media, as well as the suboptimal utilization of local potential (edupark). To address these issues, the integrated edupark learning website is viewed as an innovative solution to support the Merdeka Curriculum and enhance the quality of physics education.

Abstract

This study investigates groundwater flow and nitrate transport in the Kasin Sub-watershed, Malang City, using Visual MODFLOW integrated with the MT3DMS module. Hydrogeological and geoelectrical data, groundwater levels, and nitrate concentration measurements (110 ppm) were used as model inputs. A transient simulation over 3,600 days (±10 years) was conducted to analyze plume migration. The results show that groundwater flow follows topographic gradients, moving from upland recharge zones to lowland discharge zones, with an average velocity of 0.25–0.40 m/day. The nitrate plume migrated southward, extending ±600–700 m horizontally and reaching ±25 m in depth. High concentrations (>100 ppm) remained near the source, while concentrations decreased to 20–40 ppm at greater distances due to advection and dispersion. Vertical sections indicated plume penetration into deeper aquifers, influenced by hydraulic pressure differences between strata, while permeable sandy and pumice tuff layers facilitated migration and clay acted as aquitards. These findings highlight the persistent nature of nitrate contamination, the role of aquifer heterogeneity, and the vulnerability of groundwater in urban catchments. In conclusion, nitrate pollution poses long-term risks to groundwater quality, emphasizing the importance of monitoring networks, aquifer protection policies, and improved land-use management to mitigate further contamination.

Abstract

Critical thinking skills among prospective elementary school teachers remain limited, requiring innovative approaches in learning. This study developed and evaluated QR Code–based teaching materials for the course Basic Concepts of Elementary School Science to enhance students’ critical thinking. Using a quasi-experimental one-group pretest–posttest design with 59 PGSD students, critical thinking was assessed through four dimensions: clarification, assessment, inference, and strategy. Results showed a significant improvement, with an average N-Gain of 0.429 (moderate), indicating meaningful progress in students’ critical thinking abilities. Score distributions shifted markedly toward higher categories, with the most consistent improvement in the strategy dimension. These findings demonstrate that QR Code–based materials not only make learning more flexible and interactive but also effectively foster higher-order thinking skills. The study concludes that integrating such materials into teacher education curricula is essential to strengthen 21st-century competencies and better prepare future elementary school teachers.

Abstract

Young coconut fibers, often found as waste, contain tannin and anthocyanin compounds that can produce various natural colors, so they can be used as organic dyes. The research method used was an experiment with a focus on testing silk thread dyeing using young coconut fiber extract dissolved in rice field water. This study aims to explore and develop the use of young coconut fibers as a source of environmentally friendly natural dyes. The results showed that young coconut fibers have the potential as organic dyes. Young coconut fiber extract with fermented rice field water solvents produced three color variations depending on the fixator used: brownish black (ferrous sulfate), gray (alum), and brown (lime). Structural tests using Scanning Electron Microscopy (SEM) proved that the dyeing process did not change the cross-sectional shape of the silk thread. In terms of tensile strength, yarn with alum fixation had the highest strength compared to native yarn, ferrous sulfate fixation, and lime fixation. Elongation tests showed the highest elasticity in yarn with alum fixation, followed by lime, ferrous sulfate, and native yarn. The color fastness test against washing at a temperature of 40°C showed a fairly good level of fastness for organic dyes from young coconut fiber
