Abstract

This study aims to develop STEM-based E-LKPD to improve environmental literacy and critical thinking skills of eighth grade junior high school students on respiratory system content, with a context of solving air pollution problems caused by waste burning in Samarinda. The background of this study is the low ability of students to relate scientific concepts to local environmental issues and their weak critical thinking and environmental literacy skills in biology learning. The research method used was Research and Development (R&D) with Thiagarajan's 4D (Define, Design, Develop, Disseminate) model. Experts validated the product in subject matter, media, and language, and its practicality was tested through a student response questionnaire. The effectiveness test was conducted using a pretest-posttest control group quasi-experimental design in four public junior high schools in Samarinda (SMPN 1, 7, 19, and 26). The expert validation results showed that the product was highly valid with an average percentage of 91.66%. The practicality test resulted in a very practical category at the dissemination stage (average score of 3.5–3.7). The effectiveness test proved that the experimental group using STEM-based E-LKPD experienced a significantly higher increase in environmental literacy and critical thinking skills compared to the control group, with a medium-high N-Gain category (0.4–0.8) and statistical significance of p < 0.05. These findings suggest that anchoring STEM learning in the tangible, local issue of air pollution in Samarinda effectively bridges the gap between abstract scientific concepts and real-world application, thereby fostering deeper environmental literacy and critical thinking. The study concludes that the developed STEM-based E-LKPD is a feasible, practical, and innovative medium aligned with the Merdeka Curriculum and the Sustainable Development Goals.

Abstract

Critical thinking skills are a key component required in completing independent tasks (Sukenda, 2016). This study aims to analyze correlation between students' critical thinking skills and the quality of independent assignments in Histology courses. The research method used was a correlational quantitative approach involving 35 Biology Education study program students who were taking Histology courses. Data were collected through a histology context-based critical thinking test and independent assignment assessment using an analysis rubric. The correlation test results showed a positive correlation between critical thinking skills and the quality of students' independent assignments (r = 0.244, p < 0.05). This finding indicates that although there is a positive correlation coefficient between critical thinking ability and independent assignment quality, the significance value (Sig.) of 0.157 indicates that the correlation is not statistically significant. Based on this data, it can be concluded that there is no significant correlation between students' critical thinking skills and the quality of their independent assignments in the Histology course.

Abstract

This study aims to determine the relationship between environmental knowledge and environmental awareness among students of SMP Negeri 40 Samarinda. Awareness of the importance of protecting the environment needs to be instilled from an early age through increasing knowledge and developing environmental awareness among students. Lack of environmental awareness, such as littering and not maintaining school cleanliness, shows the importance of environmental knowledge in developing students' environmental awareness. This study was conducted to examine the relationship between environmental knowledge and environmental awareness among students of SMP Negeri 40 Samarinda. This study used a quantitative approach with a correlational method. Data collection was carried out through questionnaires given to students as research respondents. The data obtained were analyzed using normality tests and correlation hypothesis tests. The results showed that the data were normally distributed. Based on the results of the hypothesis test, a correlation coefficient value of 0.345 was obtained, which is included in the low category, thus indicating a low positive relationship between environmental knowledge and students' environmental awareness. This positive relationship indicates that the higher the students' environmental knowledge, the better the environmental awareness they have. However, the low correlation value indicates that environmental knowledge does not fully influence students' environmental awareness, as other factors contribute, such as habits, the surrounding environment, and the inculcation of environmentally conscious behavior in daily life. Therefore, supporting efforts through environmental education and programs in schools are needed to optimally develop students' environmental awareness and attitudes.

Abstract

Anthracnose is a disease that often attacks cayenne pepper (Capsicum frutescens L.). This study aims to identify fungal species and determine the morphological characteristics of fungi found in white cayenne pepper fruit of the F1 Bhaskara Hybrid variety with anthracnose symptoms from the farmland of Tondoh Village, Mook Manaar Bulatn District, West Kutai Regency. The type of research used is qualitative descriptive, namely symptomatic fruit samples were isolated using the direct planting method (direct plating) on ​​Potato Dextrose Agar (PDA) media, and fungal identification was carried out by observing the macromorphological and micromorphological characteristics of the fungus. The results showed that there were three types of fungi that were successfully isolated, namely Colletotrichum sp., Pythium sp., and Rhizoctonia sp. Colletotrichum sp. has white colonies with a cotton-like texture, septate hyphae, and cylindrical conidia. Pythium sp. is characterized by non-septate hyphae and spherical sporangia. Rhizoctonia sp. have light brown colonies with septate hyphae and perpendicular branches forming approximately 90° angles. The presence of these three fungi indicates that in addition to Colletotrichum sp. as the primary cause of anthracnose, there are accompanying pathogens that exacerbate damage and accelerate fruit decay. The results of this study serve as the basis for developing anthracnose control strategies.
