Abstract

Lombok Island harbours a rich butterfly fauna that plays a vital ecological role as pollinators and bioindicators of ecosystem health. This study investigated butterfly species diversity in the paddy field area of Paokmotong Village, East Lombok Regency, using an exploratory survey method across five observation zones: the northern, southern, eastern, and western field edges, and the central field transect. A total of 49 individuals belonging to eight species from three families (Pieridae, Hesperiidae, and Nymphalidae) were recorded. Eurema blanda and Leptosia nina (both Pieridae) were the most abundant species, while Nymphalidae exhibited the highest species richness with five species. The Shannon-Wiener diversity index (H') was calculated at 1.898, indicating moderate diversity. This value reflects a relatively stable habitat condition in terms of food availability, temperature, humidity, wind speed, and light intensity. The moderate diversity level suggests that, while the paddy field ecosystem of Paokmotong provides a reasonably supportive habitat for butterflies, environmental pressures such as pesticide use and low plant diversity may be limiting species richness. Conservation of wild flowering vegetation along field margins is recommended to sustain and enhance butterfly diversity in this agricultural landscape.

Abstract

Natural Science learning in elementary schools plays a crucial role in building students' scientific thinking skills. However, understanding basic optical concepts such as light, reflection, refraction, propagation, and shadow formation remains a significant challenge. This study aims to analyse the factors causing students' learning difficulties in understanding basic optical concepts through a literature review. The method employed was a review of eight scientific articles published between 2020 and 2026, sourced from Google Scholar and SINTA, using content analysis techniques. The findings show that students still experience misconceptions in optical concepts, particularly in reflection, refraction, and light dispersion. Learning difficulties are influenced by internal factors such as low prior understanding, limited abstract thinking ability, and learning motivation as well as external factors, including the dominance of lecture-based methods, insufficient learning media, limited practicum activities, and suboptimal use of diagnostic instruments. Efforts to address these difficulties can be pursued through conceptual change strategies, the Predict-Observe-Explain (POE) model, multiple representations, and the use of virtual laboratories to help students visualise abstract concepts in a more concrete and meaningful way.

Abstract

The widespread misuse of sodium tetraborate among informal food producers highlights the urgent need for eco-friendly, independent food screening methods. This study aimed to validate the effectiveness of turmeric rhizome (Curcuma longa L.) as an initial screening instrument for borax in high-moisture food clusters. An experimental method was applied through direct visual contact testing of reactive curcumin extract against seven types of wet domestic food samples. Colorimetric test results showed that deep orange boron cyano curcumin (rosocyanine) complex formation was detected exclusively and positively in yellow noodle samples. Six other products chicken meatballs, fish balls, pempek, white tofu, vermicelli, and crackers were confirmed negative. It is concluded that the alkaline-induced structural degradation triggered by this local natural indicator demonstrates precise reactive sensitivity, is economically viable, and is applicable as a communal preventive solution for enhancing household food safety literacy.

Abstract

The misuse of borax as a preservative in school snacks poses a serious threat to food safety, necessitating practical and accessible solutions for the general public. This study aimed to evaluate the effectiveness of purple cabbage (Brassica oleracea var. capitata f. rubra) extract as a natural indicator for the qualitative detection of borax. Laboratory experiments were conducted at the Biology Laboratory of Universitas Negeri Medan using the maceration method with water as the solvent to extract anthocyanin pigments. Food samples tested included meatballs, tofu, yellow noodles, and crackers. The results showed that purple cabbage extract successfully detected borax in yellow noodle samples through a colour change from purple to bluish-green, caused by the deprotonation of anthocyanins under alkaline conditions. These findings demonstrate that purple cabbage extract is a valid, economical, practical, and environmentally friendly screening tool to support public food safety monitoring.

Abstract

Physics education in Indonesia tends to be abstract, with the connection between physics concepts and students' everyday experiences often remaining unclear. This study maps the physics concepts embedded in the mechanism of the traditional bamboo snap gun (bedil jepret bambu) game as a source of contextual learning. A descriptive qualitative method was employed, based on conceptual analysis of the literature and field data (observation and interviews). The analysis reveals that the mechanism of the bamboo snap gun involves the concepts of elasticity (Hooke's Law), force and acceleration (Newton's Laws), work and energy, impulse and momentum, and parabolic motion. These findings indicate the significant potential of the bamboo snap gun as a physics learning medium that links theory with local cultural contexts. In conclusion, this conceptual mapping can serve as a foundation for developing innovative local-wisdom-based teaching materials to strengthen students' conceptual understanding.

Abstract

Low science learning achievement and insufficient active student engagement have necessitated the adoption of innovative instructional strategies. This study aimed to evaluate the effectiveness of a Project-Based Learning (PjBL) model integrated with educational board games on the learning outcomes of eighth-grade students at State Junior High School 26 Makassar, with a focus on Biotechnology content. A Classroom Action Research (CAR) design following the Kemmis and McTaggart spiral model was employed across three consecutive cycles, involving 29 students. Data were collected through pretest–posttest instruments and formative assessments administered at the conclusion of each cycle. Results indicated a progressive improvement in learning outcomes, with mean scores rising from 67.1 in Cycle I to 72.4 in Cycle II and 77.9 in Cycle III, alongside an improvement in class mastery rates from 44.8% to 58.6% and 68.9%, respectively. Normalised gain (N-Gain) analysis across cognitive indicators C1–C4 yielded an overall mean of 0.33, classified as moderate. The integrated PjBL and educational board game model demonstrably enhanced cognitive learning outcomes and fostered active, collaborative, and enjoyable learning environments. These findings support the adoption of this integrated approach as a viable pedagogical alternative in science education at the junior secondary level.

Abstract

Philosophy of Science is a key component of science teacher education because it helps prospective teachers understand the nature of scientific knowledge, its justification, and its educational value. This descriptive qualitative study analyzed essay responses from 78 pre-service science teachers at Makassar State University who participated in a multiplatform game-based Philosophy of Science course. Four essay questions assessed understanding of ontology, epistemology, axiology, and the integration of these three dimensions within junior secondary science education. Data were examined through qualitative content analysis supported by codebook development, repeated reading, peer review, negative-case analysis, and descriptive quantification. Results indicated strong understanding of ontological concepts (95.0% valid responses) and axiological reasoning (96.3%), while epistemological understanding was less developed (59.6%). Integrating the three philosophical dimensions proved most challenging, with only 53.8% valid responses and 40.5% demonstrating complete synthesis. Students primarily recommended debate-based games (31.3%), reflecting an emphasis on critical thinking. These findings provide a framework for assessing philosophical reasoning through essays in game-based science teacher education.

Abstract

The Teaching Profession course serves as a foundational subject in developing professional competencies for pre-service science teacher students. This study aimed to analyze the profile of professional competency achievement of pre-service science teachers through this course and to compare achievement outcomes across Regular Class A, Regular Class B, and the International Class Program (ICP) in the even semester of the 2025–2026 academic year at State University Makassar. A comparative quantitative design (ex-post facto) was employed, involving 100 students from three classes (Reg A: n=37, Reg B: n=33, ICP: n=30). Final course scores were analyzed descriptively and inferentially using the Kruskal-Wallis test, with Mann-Whitney U tests applied as supplementary pairwise comparisons. Results showed an overall mean score of 84.45 (SD=9.04), with the majority of students categorized as Good to Excellent. No significant difference was found in professional competency achievement across the three classes (H=0.533; p=0.766), with very small effect sizes across all pairwise comparisons (r<0.10). These findings indicate that professional competency attainment is equitable across class types, suggesting consistent and fair implementation of the Teaching Profession course. The study recommends strengthening student-centered learning strategies and developing comprehensive authentic assessments, including reflective portfolios, performance rubrics, and case-based tasks, to produce more robust evidence of professional competency attainment.
