Abstract

One of the common issues in the learning process is the low learning outcomes of students, which can be caused by various factors, including low emotional intelligence, learning independence, and learning motivation. This study aims to determine the relationship between emotional intelligence, learning independence, and learning motivation with the science learning outcomes of eighth-grade students at public junior high schools in Panca Rijang Subdistrict, Sidrap Regency. This is a quantitative study using a correlational approach. The study population consists of all eighth-grade students from four public junior high schools, with a sample size of 153 participants selected using simple random sampling. The research instruments include a Likert scale questionnaire to measure emotional intelligence, learning independence, and learning motivation, as well as a multiple-choice test to assess science learning outcomes. The data analysis technique used was path analysis with the assistance of SPSS 25.0. The results of the study showed a significant direct relationship between emotional intelligence, learning independence, and learning motivation with science learning outcomes. Additionally, learning motivation was found to act as an intervening variable that partially mediated the relationship between emotional intelligence and learning independence on science learning outcomes. In conclusion, strengthening emotional intelligence, enhancing learning independence, and developing learning motivation simultaneously can positively contribute to improving students' science learning outcomes. Therefore, a holistic and character-development-oriented learning approach is needed.

Abstract

The use of essential oils as complementary therapy for various health conditions, especially those involving the central nervous system (CNS), is gaining increased attention. Anxiety disorder, a common CNS-related condition characterized by excessive worry and fear, is one of the main targets for such therapies. Essential oils from various plants contain bioactive compounds that act on the CNS and exhibit anxiolytic potential. This systematic literature review aimed to assess the anxiolytic bioactivity of essential oils and identify the most effective types used for anxiety reduction. Preclinical studies from seven journals revealed that essential oils such as Agarwood, Bergamot, Cananga odorata, Ocimum basilicum, Lavender, Nectandra grandiflora, and Cinnamon influence animal behavior linked to anxiety reduction. Clinical reviews from eleven studies found that Lavender oil, especially due to its linalool content, was the most commonly used essential oil for lowering anxiety levels. The mechanisms include inhibition of CRF, ERK1, and CREB, antagonism of NMDA receptors, inhibition of SERT, and modulation of GABA<sub>A</sub> receptors and calcium influx. In conclusion, essential oils exhibit various bioactivities affecting the CNS, supporting their role as potential anxiolytic agents.

Abstract

Indonesia's shift from Curriculum 2013 to the Merdeka Curriculum has introduced significant challenges in biology education, particularly in formulating competency-based learning objectives. This study analyzes professional misconceptions in learning objectives using qualitative content analysis of eight curriculum documents—lesson plans and teaching modules—focused on "Environmental Change" from three provinces (Aceh, North Sumatra, Bangka Belitung). Contributors included senior teachers, junior teachers, and pre-service teachers under mentor guidance. Using Webb's curriculum alignment methodology and Bloom's revised taxonomy, we identified three misconception categories. Structural misconceptions showed 75% of documents retained outdated behavioral formats misaligned with competency-based paradigm. Semantic misconceptions demonstrated mean cognitive level drop of 2.1 levels from expected C6 to observed C1–C3 objectives. Pragmatic misconceptions revealed 62.5% used low-validity, recall-based assessments. These consistent patterns across regions and teacher experience levels suggest systemic rather than contextual issues. Professional misconceptions mirror student cognition patterns, characterized by structural coherence and resistance to surface-level correction. Addressing these requires explicit conceptual change strategies, not mere technical training. This study offers a research-based framework to inform interventions for effective competency-based biology instruction adoption.

Abstract

This study explores the evolution of science education foundations in Indonesia from 2021 to 2025 through a literature review approach. It aims to identify key trends, dominant paradigms, and contextual influences shaping the development of science teaching and learning in Indonesian formal education. The analysis reveals a significant shift from positivist to constructivist epistemologies, with increasing emphasis on inquiry-based learning, Nature of Science (NoS), and student-centered pedagogies. Curriculum reforms, particularly under the Merdeka Belajar policy, have introduced more flexible and learner-driven frameworks. However, disparities in implementation, teacher readiness, and resource availability persist across regions. Emerging trends also highlight the integration of local and indigenous knowledge into science instruction as a means to enhance relevance and inclusivity. The findings suggest that while theoretical advancements are evident, sustained efforts are needed to align policy, practice, and professional development. This review contributes to understanding how foundational shifts in science education can inform future curriculum design, teacher training, and educational policy in Indonesia.

Abstract

The gap between increased processor speed and access to the main memory wall is a significant obstacle in the optimization of modern computing systems, where today's applications require processing large data with real-time responses. This study aims to analyze the effectiveness of the implementation of cache memory technology in improving the performance of modern computing systems, focusing on: 1) identification of key parameters that affect the effectiveness of cache on various workloads, 2) evaluation of adaptive cache replacement algorithms, 3) analysis of performance trade-offs with energy efficiency and security, and 4) formulation of optimal cache architecture recommendations. The research method uses a qualitative approach through a comprehensive literature study of 2020-2024 publications from the academic databases of IEEE Xplore, ACM Digital Library, Scopus, ScienceDirect, and SINTA with thematic content analysis and comparative evaluation of various cache technology implementations. The results showed that: the multi-level caching architecture increased system throughput by an average of 37.5%; adaptive algorithms such as RRIP increased hit rate by 23.7% compared to conventional LRU; SRAM/STT-MRAM hybrid technology saves up to 44.3% energy with minimal performance overhead; and the proposed integrated framework resulted in a 34.8% performance increase with a 27.5% reduction in energy consumption. Further research is recommended to implement and experimentally test the proposed framework on various computing platforms, develop more adaptive machine learning-based cache replacement algorithms, and explore the integration of cache technology with neuromorphic computing architectures.

Abstract

This study aimed to evaluate the effects of solid oil palm waste application and mung bean (Vigna radiata L.) varietal differences on growth and yield performance in red-yellow podzolic soils in Bengkulu, Indonesia. A factorial experiment was conducted using a Randomized Block Design (RBD) with three replications. The two factors tested were four levels of solid waste application (0, 10, 15, and 20 tons/ha) and three mung bean varieties (Vima 2, Vima 4, and Vima 5). Data were analyzed using Analysis of Variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that solid waste application significantly improved plant height, number of pods per plant, pod weight, and seed weight per plant. Variety also had a significant effect on plant height at 56 days after planting. No significant interaction was observed between the two factors. Overall, the application of 20 tons/ha of solid waste resulted in the highest improvements in agronomic parameters. Among the tested varieties, Vima 5 demonstrated the best overall performance. These findings suggest that using solid oil palm waste at an optimal dose can enhance mung bean productivity in red-yellow podzolic soils, supporting sustainable agricultural practices.
