Abstract

This study maps global research trends on ethnoscience-based chemistry learning integrated with Project-Based Learning (PjBL) and the Flipped Classroom (FC) using a bibliometric approach. A total of 118 journal articles published between 2016 and 2025 were analyzed with VOSviewer to examine publication trends, keyword co-occurrence, and thematic clusters. Results show a significant increase in publications after 2020, highlighting five main clusters: (1) ethnoscience and local wisdom, (2) PjBL and active pedagogy, (3) FC and digital learning, (4) scientific literacy and 21st-century skills, and (5) bibliometric analysis and research trends. Overlay and density visualizations indicate a recent focus on PjBL–FC integration to enhance scientific literacy, while ethnoscience provides a contextual foundation. This study identifies gaps in fully integrated empirical research and offers directions for future studies and practical implications for curriculum design, teacher training, and sustainable learning. These findings provide actionable insights for educators and policymakers aiming to enhance culturally responsive, technology-supported chemistry education that promotes sustainable development aligned with the United Nations Sustainable Development Goals.

Abstract

Hypercholesterolemia is a major risk factor for cardiovascular disease and requires effective and sustainable management. The use of natural ingredients as alternative therapies is gaining increasing attention, including bay leaves (Syzygium polyanthum). This study is a literature review aimed at assessing the potential of bay leaves as an antihypercholesterolemic agent based on existing scientific evidence. The methods used included searching and analyzing various scientific articles covering in vivo studies, clinical trials, and in vitro and in silico approaches. The results of the review indicate that bay leaves can consistently reduce total cholesterol, LDL, and triglyceride levels, while improving the overall lipid profile; these findings are also presented in diagrammatic form to facilitate visualization of the data distribution. Identified mechanisms of action include inhibition of the HMG CoA reductase enzyme, decreased intestinal cholesterol absorption, improved lipid metabolism, and antioxidant and anti-inflammatory activities. Bioactive compounds such as flavonoids, saponins, tannins, and polyphenols work synergistically to produce multitarget effects on lipid metabolism. Several clinical trials have also shown significant effectiveness in patients with dyslipidemia, although there are variations in some parameters such as HDL. Despite its promising potential, the development of bay leaves as a clinical therapy still requires further research, particularly large-scale clinical trials, extract standardization, and long-term safety assessment. Therefore, bay leaves have the potential to be developed as an alternative or complementary herbal therapy for the treatment of hypercholesterolemia.

Abstract

Learning using the problem-based learning (PBL) enables students to solve problems as well as improve their science knowledge and skills. This study aims to investigate the effect of the use of PBL on critical thinking skills of high school students in biotechnology. Various levels of students’ self-confidence are used as a moderating variable for PBL in producing the effect. A total of 64 students of SMAN 8 Batanghari Jambi were involved in this study. Some 32 students were allocated each to the experimental class which was learning using PBL and the control class which was learning using the expository learning. Data were collected using a pre-validated self-confidence questionnaires and tests of critical thinking skills. The factorial type of quasi-experimental with pretest posttest nonequivalent control group design was used in this study. The collected data were analyzed using a two-way ANOVA test. The results showed that PBL-students had a higher average score of critical thinking skills (85.87) than their counterpart (78.80). The data also showed that the students with better self-confidence also have a higher average score of critical thinking skills (85.32) than those with lower self-confidence (79.34). The results of the two-way ANOVA test showed that there was an effect of the use of PBL and the students' self-confidence on students' critical thinking skills. Even though it is very weak, the interaction between the learning model and the self-confidence was seemingly existed in affecting the students' critical thinking skills. It can be concluded that the appropriate learning model and appropriate self-confidence can affect student learning critical thinking skills

Abstract

Abstrak Pembelajaran matematika berbasis budaya lokal menghubungkan konsep matematis dengan pengalaman sehari-hari peserta didik. Penelitian ini menelusuri unsur etnomatematika pada motif Batik Sarolangun dan keterkaitannya dengan konsep geometri untuk pembelajaran sekolah. Pendekatan kualitatif dengan desain etnografi digunakan, dengan data dikumpulkan melalui observasi partisipatif, wawancara mendalam, dan dokumentasi di dua sentra Batik Sarolangun. Tiga pengrajin senior dipilih secara purposif sebagai informan. Analisis data mengikuti model Spradley (domain, taksonomi, komponen, tema budaya), sementara identifikasi konsep geometri dilakukan melalui analisis visual bentuk, pola pengulangan, simetri, dan transformasi motif. Hasil menunjukkan delapan motif utama memuat bangun datar (lingkaran, elips, segitiga, trapesium, belah ketupat, setengah lingkaran, persegi panjang) serta transformasi geometri (translasi, refleksi, rotasi, dilatasi). Penelitian ini menegaskan Batik Sarolangun sebagai sumber belajar geometri berbasis budaya lokal dan menyediakan dasar empiris untuk pengembangan bahan ajar dan strategi pembelajaran yang kontekstual di SD dan SMP. Kata kunci: Etnomatematika, Batik Sarolangun, Geometri, Transformasi Geometri, Pembelajaran Matematika. Abstract Culture-rooted mathematics instruction offers a contextual route to bridging mathematical ideas with learners' lived realities. The present study seeks to investigate ethnomathematical features embedded in Sarolangun Batik motifs and to map the geometric concepts contained therein onto school mathematics content. A qualitative approach with an ethnographic design was adopted. Data were gathered through participatory observation, in-depth interviews, and documentation at two Sarolangun Batik production centres in Sarolangun Regency, Jambi Province. Three senior batik artisans were selected purposively, each with at least ten years of crafting experience and full mastery of the regional motif repertoire. Spradley's analytical stages domain, taxonomic, componential, and cultural theme analysis—guided the data interpretation. Geometric concepts were identified through systematic visual analysis of shape, repetition, symmetry, and transformation patterns. The findings reveal that eight principal motifs of Sarolangun Batik encode plane-geometry concepts (circles, ellipses, triangles, trapezoids, rhombi, semicircles, rectangles) and transformation-geometry concepts (translation, reflection, rotation, and dilation). These results suggest that Sarolangun Batik holds considerable promise as an authentic, contextual ethnomathematical resource for teaching plane figures, symmetry, and geometric transformations at the elementary and lower-secondary levels. Keywords: Ethnomathematics, Sarolangun Batik, Geometry, Geometric Transformation, Mathematics Learning.

Abstract

Natural peatlands are home to a wide variety of animals and plants and provide ecosystem services for humans and the environment. Peatlands in Jambi are still not appropriately managed, partly because of the lack of community knowledge regarding peat. This study reveals the knowledge and perceptions of junior high school students about peat, the factors that influence it, and its implementation in science learning. We conducted the study on 228 junior high school students and 21 science teachers in Tanjung Jabung Timur. Data were collected through questionnaires, observations, and focused discussions. Data were analyzed descriptively. Furthermore, the data were analyzed using Smart PLS to determine the relationship between students' background, perceptions, and interactions with their knowledge of peat. Students' knowledge of peat is in a low category. The level of student's knowledge is significantly influenced by their experiences (interactions) with peatlands and their perceptions of these resources. The student's family background does not affect students' knowledge of peat.

Abstract

Research on the potential of local tree species is crucial for the success of post-coal mining land rehabilitation. By selecting the right species, the revegetation process can be more efficient, sustainable, and provide ecological and economic benefits to the environment and surrounding communities. The implementation of post-coal mining land reclamation must be carried out based on guiding principles, one of which is to maintain environmental sustainability. The application of these principles is crucial as an effort and a form of corporate responsibility, aiming to restore the mined and cleared areas back to their natural functions. Reclamation at PT. Minemex Indonesia is currently in the stage of planting pioneer plants or fast-growing plants (Phase II). Therefore, accurate information is needed regarding the technical aspects of the next reclamation phase (Phase III), which involves planting local trees, to ensure that revegetation goals are met in accordance with the mandates of the Indonesian Ministry of Energy and Mineral Resources Regulation No. 07 of 2014 and the Ministry of Forestry Regulation No. P4/Menhut-II/2011. This study aims to inventory the types of local trees that have the potential for revegetating post-coal mining land at PT. Minemex Indonesia. The identification of local tree species that naturally grow in the forest area around the mine is carried out through vegetation analysis and calculating the importance value index for each species found. Meanwhile, the selection of tree species for revegetation is conducted by scoring based on seven selection criteria: habitus, habitat, regeneration ability, economic value, ecological value, symbiosis, and sprouting ability. Data on soil conditions in the forest area around the mine and the reclamation area are obtained from soil sample analysis. The revegetation plan is developed by considering field data before mining and field data after reclamation. The research results show the discovery of 21 species at the tree level, 24 species at the pole level, 25 species at the sapling level, and 12 tree species at the seedling level that grow naturally in and around the reclamation area of PT. Minemex Indonesia. Based on scoring against the seven selection criteria, there are 12 local tree species that have the potential for use in post-coal mining land revegetation at PT. Minemex Indonesia. These species are Vitex pubescens, Beilschmiedia gemmiflora, Alstonia scholaris, Macaranga gigantea, Bellucia pentamera, Syzygium palembanicum, Cratoxylum arborescens, Aquilaria malaccensis, Durio zibethinus, Syzygium cf. griffithii, Syzygium polyanthum, and Parkia speciosa. The planting of local tree species for post-mining land revegetation is carried out by considering important aspects in the stages of land preparation, nursery, planting, and maintenance.

Abstract

The Depati Karo Jayo Tuo Customary Forest, located within the Merangin Geopark, is a conservation forest that contains various plant species, including rattan. However, specific data on rattan species in this area are unavailable. This study aims to inventory and categorize the rattan species in the forest. Data collection was carried out by exploring the forest's trekking path. Rattan samples were collected using the quadrat plot method. The identification results revealed the presence of seven rattan species in the Depati Karo Jayo Tuo Customary Forest, namely Calamus micracanthus Griff., Calamus javensis Blume, Calamus oblongus Reinw. ex Blume, Calamus manan Miq., Calamus castaneus Griff., Calamus sp., and Korthalsia laciniosa (Griff.) Mart. Among these, Calamus oblongus Reinw. ex Blume was the most abundant species, with 1,050 individuals, while Calamus castaneus Griff. was the least abundant, with only 14 individuals recorded. According to the IUCN conservation status, all identified rattan species are classified as "Not Evaluated." Similarly, rattan is not listed as a protected species based on Indonesian Government Regulation No. 7 of 1999. Additionally, data from CITES indicate that rattan is not involved in international trade
