This study aims to examine the effectiveness of STREAM-integrated Project-Based Learning This study investigates the effectiveness of a Project-Based Learning (PjBL) model integrated with the STREAM–ESD (Science, Technology, Religion, Engineering, Arts, Mathematics – Education for Sustainable Development) approach in enhancing junior high school students’ critical thinking skills within the topic of biotechnology. Utilizing a quasi-experimental design, the research was conducted on Grade IX students in South Cianjur, West Java, through a kombucha tea production project grounded in real-world application and interdisciplinary inquiry. The intervention involved four stages: problem definition, data collection, building, and utilization. Results from pretest and posttest assessments revealed a significant increase in critical thinking skills in the experimental group (N-Gain = 0.7057, high category) compared to the control group (N-Gain = 0.4514, moderate category), with statistical tests confirming a meaningful difference (p < 0.05). The findings demonstrate that the integration of STREAM and ESD into PjBL fosters analytical thinking, creativity, and moral reasoning through contextual learning experiences. Moreover, the inclusion of ethical and religious perspectives encouraged students to consider the social and spiritual implications of scientific practices. This research contributes to the ongoing discourse on educational innovation by offering a sustainable, student-centered, and culturally responsive model for science education aligned with the goals of Indonesia Emas 2045 and the UN Sustainable Development Goals

The 3-dimensional LED board of the digestive system (PALED 3D-SD) is a learning media that was developed on the basis of analyzing the problems and needs of students. Based on the results of observations in the field, students still have difficulty in learning, especially in understanding the concept of the human digestive system material so that it has an impact on learning outcomes that are not optimal. This is due to the character of the material of the digestive system that cannot be sensed directly by the five senses of students. The learning media used so far have not optimally facilitated students' understanding of concepts. The availability of visual media (torso) of the human digestive system in schools has not been able to display a wide range of material, namely showing the flow of human digestive bioprocesses. This study aims to analyze the validity of the PALED 3D-SD media developed according to media experts and material experts, analyze the practicality of the media according to teachers and students, and analyze the effectiveness of the media in improving students' conceptual understanding through indicators of N-gain test results, class classical completeness, and average difference test. This research is a type of R&D (research & development) research using the ADDIE model through the analysis, design, development, implementation, and evaluation. The validity test of PALED 3D-SD media was obtained from the assessment of 2 media experts and 2 material experts. The practicality test of the media used samples from class XI MIPA 9 and teachers at SMA N 5 Semarang, while the media effectiveness test through a quasi-experimental design used samples from class XI MIPA 5 (control class) and XI MIPA 6 (experimental class) at SMA N 12 Semarang. The results of the media validity test show that the PALED 3D-SD media is very valid according to media experts and material experts. The results of the media practicality test show that the PALED 3D-SD media is considered very practical according to students and teachers. The results of the media effectiveness test show that PALED 3D-SD is effective in improving students' conceptual understanding based on the results of the N-gain test which is in the medium category, the results of classical class completeness are obtained by the percentage of completeness that has met the effective criteria and is higher than the control class, and the test results average difference statistic which shows that there is a difference in learning outcomes (concept understanding) between the group that learns to use PALED 3D-SD and the group that learns to use video. The conclusion based on this research is that the PALED 3D-SD media developed is valid, practical, and effective in improving students' conceptual understanding.

The change in curriculum to the Merdeka Curriculum provides a lot of changes in learning strategies, approaches, methods and models. Students need learning methods that can bring them to have the ability to be responsive to local, national and global issues and play an active role in providing problem-solving solutions. The purpose of this study was to test PjBL and JAS-based learning using student worksheets as learning tools. Students are asked to actively discuss, observe, explore and create a product. The N-Gain test results show that student worksheets are effective for improving students' problem solving skills and creativity. Problem solving ability and creativity of experimental class students are better when compared to control class students. The Mann-Whitney Test results show that there is a significant difference in value between the control class and the experimental class. Classical learning completeness of experimental class students was better than control class students.

This research aims to develop a biodiversity encyclopedia based on the local potential of Batang Gadis National Park (BGNP) as a learning resource for Grade X students of general Senior High Schools (SMA) and Islamic Senior High Schools (MA). This research is driven by the lack of biodiversity supporting learning resources other than textbooks and student worksheets, where, for every biodiversity material, teachers have to print original pictures of plants/animals along with their morphological characteristics. This research used the Research and Development (R&D) method with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The study was conducted from April to August 2025 at MAN 1 Mandailing Natal. Data collection was carried out through literature review, interviews, and validation questionnaires for material, media, and practicality from biology teachers and students. The data were analyzed quantitatively using a validity formula complemented with criteria, processed through Excel. The research results showed that the material expert validation was 97% (very valid), media expert validation was 100% (very valid), teacher practicality was 97% (very valid), and the small-scale trial of the encyclopedia product obtained a percentage of 94% (very good). Therefore, it can be concluded that the biodiversity encyclopedia of Batang Gadis National Park, Mandailing Natal, is feasible to be implemented as a supplementary learning resource.

Interviews with biology teachers at MA Al-Qodiri Kalipuro, Banyuwangi found that they need a printed learning media about biodiversity to support student’s motivation on learning process. On the other hand, the school environment has a diversity of plants, so this diversity can be used to develop a contextual-based booklet learning resource. This research aims to determine the quality of contextual-based booklet as a learning media for students in MA Al-Qodiri Kalipuro. This is a Research and Development that using the 7 steps of the Borg and Gall research method which has been modified by Sugiyono. The 7 steps of the research method are: potential and problems, data collection, product design, design validation, design revision, product testing, product revision. The research results from the material expert validation results obtained a percentage of 97.27% in the very valid category, or can be used without revision. The assessment from media experts obtained a percentage of 98.18% in the very valid category, or can be used without revision. The user response test by students obtained a percentage score of 80.75% in the very appropriate category. Meanwhile, the user response test by the teacher obtained a percentage score of 80% in the appropriate category. Thus it can be concluded that Booklet media can be used as a learning medium that is able to motivate students to learn, so that it can make a positive contribution in increasing the effectiveness of biology learning in schools.
