Abstract

Microplastics are plastic particles smaller than 5 mm that originate from anthropogenic activities or environmental degradation. The estuarine waters of the Kenyamukan River in Sangatta, East Kutai Regency, are highly vulnerable to microplastic contamination due to intensive local activities such as fishing port operations, residential settlements, docks, and tourism sites. This study aimed to analyze the types and forms of microplastics found in several fish species inhabiting the estuarine area. The research employed a descriptive–analytical approach, with sampling conducted from March to May 2025. Fish organs analyzed included the gills and digestive system, which were extracted using NaCl solution, 10% KOH, and 30% H₂O₂, followed by observation under a stereo microscope. The results revealed the presence of microplastics in goatfish (Parupeneus indicus), spotted scat (Scatophagus sp.), rabbitfish (Siganus guttatus), and golden snapper (Lutjanus johnii). The identified microplastic types consisted of fibers (52%), fragments (27%), films (12%), and pellets (9%), with a total of 173 particles. The microplastic sizes ranged from 0.0012 mm to 0.1399 mm and exhibited various colors, including black, red, yellow, blue, green, transparent, orange, and pink. These findings indicate a high level of microplastic contamination in the Kenyamukan River estuary, posing potential threats to the aquatic ecosystem and the trophic food chain.

Abstract

The results of observations conducted by researchers on February 2, 2025 with teachers at SMP Negeri 11 Samarinda show several problems, including the low critical thinking skills of students, learning outcomes that are not optimal, and the lack of use of digital media and innovative learning models. This condition causes students to have difficulty in understanding the learning material delivered by the teacher. This study aims to determine the influence of the Problem Based Learning (PBL) learning model based on Reading, Questioning, and Answering (RQA) on students' critical thinking skills and learning outcomes by using the Wordwall application at SMP Negeri 11 Samarinda. The research method used is a correlational method with a quantitative approach. The sampling technique was carried out by purposive sampling with classes VII-I and VII-H as research samples. Data analysis using t-test. After applying the RQA-based PBL learning model in class VII-H as an experimental class and given a critical thinking ability test and a learning outcome test, the average score of the experimental class was higher than the control class. The results of the data analysis showed that in the control class, the level of significance of critical thinking skills was 0.000 < 0.05 and learning outcomes were 0.002 < 0.05. This shows that the application of the RQA-based PBL learning model has a significant effect on improving students' critical thinking skills and learning outcomes on ecology and biodiversity materials at SMP Negeri 11 Samarinda. These findings prove that the application of the RQA-based PBL model is effective in improving students' critical thinking skills and learning outcomes.

Abstract

The average biology learning outcomes of eleventh-grade students at MA Negeri 1 Samarinda are still below the Minimum Completion Criteria (KKM), while innovative learning models such as POE (Predict-Observe-Explain) have never been implemented. Biology learning has been mostly based on lectures, discussions, assignments, and practicums, while scientific attitude assessments are only taken from daily life and practicum activities. This condition requires the implementation of a model that can actively involve students to encourage scientific attitudes and science process skills (SPS). This study aims to determine the effect of the POE model on the scientific attitudes and SPS of eleventh-grade students on the sensory system material. The method used is a quasi-experimental design with a Nonequivalent Control Group Design, involving class XI-F as the experiment and XI-D as the control. The research instruments are scientific attitude questionnaires and SPS tests. The results of the analysis show significant differences between the experimental and control classes in scientific attitudes (p < 0.05) and SPS (p < 0.05 with the Mann Whitney U test). Improvements in scientific attitudes were demonstrated by an N-gain of 0.35 (moderate) in the experimental class and 0.19 (low) in the control class. Meanwhile, the N-gain of the Student-Based Learning (KPS) reached 0.60 (moderate) in the experimental class and 0.29 (low) in the control class. The conclusion of this study is that the POE model effectively improves the scientific attitudes and science process skills of eleventh-grade students at MA Negeri 1 Samarinda.

Abstract

The low understanding of concepts can be caused because the learning process is not maximized which makes students inactive, unable to think independently, more practical to find answers on the internet, and unable to express what they have learned. Digital School Books as a medium and learning model Survey, Question, Read, Reflection and Review (SQ4R) is an alternative that can activate students and make it easier to remember concepts so that learning is more meaningful. The purpose of this study was to describe the effect of the SQ4R learning model with digital school books on students' understanding of biology concepts in class VII at the Madrasah Tsanawiyah Nurussa'adah Sangkulirang Islamic Boarding School. This research is a quasi-experimental study with a pretest-posttest control group design. The study population was students of class VII, using cluster random sampling technique which produced class VII.B as the experimental class and class VII.A as the control class. The results of the data analysis showed that there was an influence of the SQ4R learning model with digital school books on the understanding of biology concepts for class VII students at the Madrasah Tsanawiyah Nurussa'adah Sangkulirang Islamic Boarding School.

Abstract

Shading causes differences in light intensity that trigger physiological and morphological variations in leaves, including stomata density and size as a form of adaptation to balance photosynthesis and transpiration. This phenomenon is the basis for selecting the research, because it illustrates the adaptive ability of plants to changes in the microenvironment in their natural habitat. This study aims to analyze the density and size of stomata of dicotyledonous plants growing in shaded and open areas in the Sempaja Arboretum. This study uses a descriptive quantitative approach with samples of several dicotyledonous plant species growing in shaded and open areas. Data were obtained through microscopic observation of leaf epidermis preparations using direct section techniques, optilab, and image raster 3. Statistical analysis showed that the density of stomata in open areas was higher (480 stomata/mm²) than in shaded areas (323 stomata/mm²). However, the size of the stomata did not show a consistent pattern; The average length (25.21 µm) and width (18.45 µm) of stomata in the shaded area were slightly larger than those in the open area (24.16 µm and 17.18 µm). These results indicate that high light intensity encourages increased stomatal density as an adaptive mechanism to support photosynthesis.
