This research aims to create an electronic teaching module for high school phase E students based on project-based learning about viruses. This kind of study uses a 4-D model for research and development. The four phases of the 4-D model are definition, design, development, and dissemination. The 4-D model is modified in this study for the validation stage of development. Eight high school teachers and two biology lecturers made up the research subjects. Using a modular application, an electronic teaching module for viral material based on project-based learning is the research object. A validity questionnaire is used as the data-gathering tool. The average value of the language expert assessment is 89.58% very good credentials, and the average value of the material expert assessment is 88.27% very good qualifications, according to the research findings. The expert evaluation assessment has 80.00% good credentials, the media expert assessment has 86.19% very good qualifications, and the teaching equipment expert assessment has 95.13% very good qualifications. With very good credentials, the entire average validity value is 87.83%. We may infer that an electronic teaching module for high school phase E students based on project-based learning about viruses has been created using very reliable criteria and is appropriate for usage.

This research aims to determine the types of tree strata vegetation, calculate the Importance Value Index and Diversity Index in Pesanggerahan Gembirowati, and the relationship between abiotic environmental conditions (air temperature, air humidity, soil temperature, soil moisture, pH, and light intensity) on stand grouping patterns, The potential for research results as a source of biology learning in biological material is high. This research is exploratory. Data collection uses Point Centered Quarter. The diversity index uses Shannon-Wienner and the correlation of measured abiotic environmental conditions (air temperature, air humidity, soil temperature, soil water content, pH, and light intensity) with stand grouping patterns using the SPSS 20 cluster program. Potential learning resources are carried out by descriptive assessment. The research results showed that there were 20 types of tree strata. The highest INP was Cocos nucifera L. (50.0%) and the lowest INP was Muntingia calabura L. (2.9%). The tree strata diversity index is classified as moderate, ranging from 1.09 to 1.19. Abiotic environmental conditions are interrelated and withstand grouping patterns. The research results have the potential to be a source of Biology learning in high school.

The development of popular scientific books with local potential is believed to be able to support learning resources based on local potential. Popular scientific books are structured as learning resources for enrichment materials for the Zingiberidae subclass in the Phanerogamae course. Known as the ginger family, Zingiberaceae is widely used in Southeast Asia, especially Indonesia for its unique taste, ornamental appeal, and medicinal value. The purpose of this study was to describe the species diversity of Zingiberaceae in Barimbun Village, Tabalong Regency, and to describe the suitability, feasibility, and readability of the results of the development of a popular scientific book on Zingiberaceae Diversity in Barimbun Village, Tabalong Regency. The research method used is research and development (R&D) concerning the 4D development model. Based on the research results, 7 species were obtained consisting of the genera Amomum, Alpinia, Curcuma, Zingiber, and Kaempferia. The results of the suitability test were stated to be very suitable with a value of 4.5. The results of the feasibility test were declared very feasible with a value of 4.3. The results of the readability test by students were stated to be very good with a value of 4.5.

Critical thinking skills in the 21st century need to be developed including the ability to evaluate, analyze, and use information to solve real-world problems. To put these skills into practice, a tool enriched with practical information based on experience has been created in the form of an encyclopedia, supported by various aspects of critical thinking in an encyclopedia book. This is a book containing information about all sciences in the form of a series of articles arranged alphabetically by title. The purpose of this study was to determine the relevance and practicality of the contents of the Sapindaceae Encyclopedia of the Banua Botanical Gardens. This study focuses on the development of assessments using the Educational Design Research (EDR) model using Tessmer's formative design. Research has found that the validity of this encyclopedia falls into the category of "good" as it contains content that teachers and students can use and the systematic structure of the encyclopedia is excellent. Content practice evaluation results are classified in the "good" category because they contain content that is suitable for subject activities, the structure of the book is interesting and easy to understand, and they can train students' critical thinking skills.

The objective of this study is to find out if using evolution learning videos is an appropriate solution to existing challenges, as well as to assess their impact on science process skills and critical thinking abilities in class XII at SMAN 2 Yogyakarta. This is a quasi-experimental study with a non-equivalent pre-test and post-test control group design. Purposive sampling is used in this study. The research classes were XII IPA 2 (control) and XII IPA 3 (experimental). The data collection strategies utilized include pretests and posttests, as well as non-test techniques such as learning implementation analysis sheets. Sampling was carried out three times: once before the test and twice after the test. The test is multiple-choice, with 15 questions based on markers of science process skills and critical thinking ability. The Mann-Whitney Test, Wilcoxon Test, Effect Size Test, and N-Gain Test can all be used to determine the effect of evolution learning films. The outcomes of this study indicate that evolution learning video media is an alternate solution for SMAN 2 Yogyakarta students that enhances their science process skills and critical thinking abilities.

The Sultan Adam Mandiangin Grand Forest Park has a high biodiversity with a variety of plants. This study aims to describe the types of macroscopic fungal found in the Sultan Adam Mandiangin Grand Forest Park area. The data were obtained using the total roaming method, and then the morphological characteristics of each sample of macroscopic fungal were found. Data analysis was carried out by identifying species concerning the literature. The results of the study found 18 species of macroscopic fungi, belonging to 7 families, namely: Marasmius elegans, Marasmius sp.1, Marasmius sp.2, Polyporus alveolaris, Neofavolus alveolaris, Polyporus sp., Trametes hirsuta, Trametes gibbosa, Trametes sp., Fomes sp., Lycoperdon sp., Lycoperdon pyriforme, Irpex lacteus, Thelephora terrestris, Ganoderma sp.1, Ganoderma sp.2, Daldinia sp., dan Daldinia concentrica. The results of this study are expected to provide information about the biodiversity of macroscopic fungi in South Kalimantan.

Because the residents of Sungai Rasau sub-district constantly run out of water to satisfy their daily requirements when the dry season arrives, this project-based learning takes the shape of creating a filtration tool. The purpose of this study is to ascertain how the project-based learning approach has affected the student's capacity to solve problems related to environmental pollution at SMAN 5 Singkawang. With a single group pretest type—tests and observation sheets—this study approach employs an experimental pre-experimental design. According to the study's findings, the average pretest score was 47.49, while the average posttest score was 76.37. An N-Gain rating of 1.11 indicates improved problem-solving skills (high). The impact size calculation yields a value of 4.02 (high). In class X SMA Negeri 5 Singkawang, it can be inferred that the project-based learning approach significantly influences students' problem-solving skills and their understanding of environmental degradation.
