Abstract

Background: Local wisdom is ideas in an area that are wise, valuable, and become a tradition and are followed by the people there. By integrating local wisdom in the learning process, it will provide more meaning and real experience to students that the surrounding environment contains local wisdom that must be preserved. This research aims to determine the level of knowledge of junior high school students around Rawa Pening lake regarding the local wisdom of Rawa Pening lake in relation to science learning materials. Method: The type of research used is quantitative descriptive research. The subjects of this research were class VIII junior high school students around Rawa Pening lake. The data collection techniques used are observation, interviews, tests and documentation. The instruments used were interview sheets and test questions. The data analysis used is by analyzing student test scores. The local wisdom found around Rawa Pening lake is the tradition and the use of natural resources. Result: Based on the results of the analysis of students' knowledge about the local wisdom of Rawa Pening lake, it was found that 83% (231 student) were in the "poor" category, 15% (41 student) were in the "sufficient" category, 3% (8 student) were in the "good" category, and no students were found who had knowledge in the "very good" category. Conclusion: Recommendations for learning strategies based on local wisdom can be carried out through project-based learning, folklore-based learning, and nature-based learning.

Abstract

The Classroom Action Research (CAR) training for Science and Biology teachers in Salatiga aims to enhance pedagogical competence through a research-based approach. The implemented activities adopted a collaborative-participatory model, involving eight teachers through three main stages: (1) a joint needs identification with the local teachers' working group (MGMP), (2) intensive training across four interactive sessions, and (3) continuous mentoring. The training methods combined the presentation of conceptual material (CAR framework, data collection techniques), hands-on proposal drafting practice, and simulations on using research tools like Mendeley for reference management. Evaluation results indicated positive outcomes, with 100% of participants rating the facilitators as highly competent and 87.5% stating the material was presented clearly. However, a need for deepening practical aspects was identified, as 12.5% of participants still experienced difficulties in application. Thematic analysis of the feedback revealed three main recommendations: (a) increasing the portion of case-based learning activities using real examples, (b) developing applied biology-based modules, and (c) integrating technology such as digital microscopy in advanced training. The program's success is reflected in 80% of participants' ability to design relevant CAR proposals during the training, and the establishment of an online learning community for post-activity mentoring. These findings emphasize the importance of a teacher training model that combines applicable theory, intensive mentoring, and technological support, particularly to bridge the gap between academic research and classroom practice.

Abstract

This research aims to determine the profile of critical thinking skills of Class VII middle school students on ecology and biodiversity material using quantitative descriptive research with data collection techniques using tests, analysis using a quantitative approach consisting of empirical validity, reliability, differentiation, level of difficulty and data analysis scores, and research design using pretest - posttest design, data collection techniques using critical thinking questionnaires, data analysis techniques by looking at interpretation results and N - Gain. The research results of students' critical thinking skills at the beginning of the test (pre-test) reached an average score of 47.49, while the average score of students at the end of learning (posttest) reached 64.09. Based on the interpretation results, it shows that the pre-test results are in the poor category with a total of 63 students (100%), while the post-test scores in the interpretation results show that there are 17 students (26.98%) in the sufficient category and 46 students (73.02%) in the insufficient category. So it can be said that there may be many factors that cause students to lack enthusiasm in science subjects on ecology and biodiversity, including the lack of variety in the methods used in teaching.

Abstract. Hastuti SP, Sucahyo, Cahyaningrum DC, Nugroho RA. 2025. Home-made and commercial eco-enzymes alter plankton communities and water chemistry in Rawa Pening Lake, Central Java, Indonesia. Biodiversitas 26: 3843-3854. Eco-enzymes are increasingly used to improve water quality by reducing organic pollutants and balancing nutrient levels in rivers and other aquatic systems. However, their typically low pH and high concentrations of organic matter may increase Biological Oxygen Demand (BOD) and acidify the water, potentially altering freshwater plankton species composition and increasing the risk of eutrophication in aquatic ecosystems. This study aimed to assess the effects of commercial and home-made eco-enzyme on freshwater plankton community structure and water quality parameters using a controlled aquaria design with four concentrations (2.5-20% v/v). Controls without eco-enzymes were included for comparison. Key parameters including nutrient levels, BOD, Total Dissolved Solids (TDS), pH, plankton diversity and abundance were monitored throughout the study. Plankton diversity across different eco-enzyme types and concentrations was compared by generating diversity profiles using Renyi’s entropy values. Results showed that both types of eco-enzymes significantly altered water chemistry. BOD declined rapidly at 5% commercial and 2.5% (v/v) home-made eco-enzyme, while pH increased from 7.4 to 8.6 over time. Ammonia, nitrite, nitrate, and TDS levels rose with both eco-enzyme concentration and duration. At higher concentrations, commercial eco-enzymes promoted the dominance of Bacillariophyta and Cyanophyta, while home-made eco-enzymes favored Bacillariophyta and Chlorophyta. Although eco-enzymes stimulated microbial activity and organic matter decomposition, they also supported the growth of pollution-tolerant plankton species, potentially reducing overall biodiversity. Renyi entropy profiles revealed decreased richness and evenness, especially at higher concentrations. These results highlight that while eco-enzymes can contribute to water quality improvement, their ecological impacts, particularly on plankton communities, must be carefully considered. Further research is necessary to ensure their sustainable and responsible use in aquatic ecosystems.

Abstract

Contraceptive pills containing 17α-ethinylestradiol (EE2) and levonorgestrel (LNG) can contaminate aquatic environments and affect fish physiology. However, studies on the effects of EE2 and LNG on fish physiology in Indonesia remain limited. This study aimed to investigate the effects of combined EE2 + LNG and fish feed on the energy reserves, specifically lipid and protein content, in female guppies (Poecilia reticulata). Fish were reared for seven days with or without feeding in 4-l aquaria containing 1 l of water (pH = 7.6 ± 0.06, temperature = 24.6 ± 2.08 ℃, BOD = 5.8 ± 0.76 mg l-1). Each aquarium contained five female fish (2–2.5 cm in length). Five EE2 + LNG concentrations were tested: 0 + 0, 3 + 15, 30 + 150, 300 + 1500, and 3000 + 15000 ng l-1, with three replicates. Lipid and protein contents were estimated gravimetrically and expressed in Joules (J). Data were analyzed using two-way ANOVA with EE2 + LNG concentration and feeding as factors, followed by Tukey’s post hoc test. Results showed no significant interaction or single factor effect of EE2 + LNG concentration and feeding on dry weight, lipid, or protein contents. Dry weight, lipid, and protein ranged from 17.8–118.0 mg, 0.01–0.49 J, and 0.29–1.94 J, respectively. Thus, exposure to EE2 + LNG did not affect the energy reserves of female guppies. This indicates that short-term exposure to EE2 and LNG at concentrations relevant to the environment does not lead to immediate disruption of energy metabolism in fish, and it also offers reference information for environmental surveillance and toxicological risk evaluation of endocrine-disrupting pharmaceuticals in water systems.
