Nur Aifiah Binti Ibrahim — 2025-01-17

An aquatic plant breathes through pores in the atmosphere, creating a bacterial loop cycle. Harmful toxins and pathogens invade the foreign substrate and recessive genes. The purpose of this study is gene editing and gene expression containing information to produce proteins and fight back pathogens. The Methodology of this study is the biosphere of RNA involved in the transcription and translation of DNA to detect several diseases. It is a narrative review of DNA biosynthesis in identifying the mutations for genes, chromosomes, or proteins. Genetic alterations in cancer development have urged many researchers to continue their expedition to find prevention strategies and treatments that are curable for the disease. Thus, gene therapies include gene augmentation, gene slicing, gene suicide, and gene editing by treating certain diseases. The momentum of replacing a damaged gene with a healthy gene using gene therapy in treating a wide range of diseases is quite impressive. An inborn child will have a healthy gene by inheriting it from the parent to the infant for further development. Circular RNAs are meant for protein synthesis. The nutrients are the building blocks of amino acids. The regrowth of new tissues is used to rejuvenate organ transplants. It is highly apprehensive for microbial cells to produce on their own. Not all bacteria are good, but the ones that fight off pathogens in the circular loops of plasmids. The DNA of bacterial cells is composed of chromosomal traits of inheritance in providing nutritious meals and becoming an antibody.

Potential development of field activity design on ecology material as student learning material

Dini Nurani Rahmawati — 2025-01-23

This study aims to analyze the design of laboratory activities (DKL) for field trips activities in the Ranca Upas heterogeneous forest and to provide solutions through reconstruction. The significance of using the field trip method to enhance student learning outcomes and environmental awareness. The Ranca Upas heterogeneous forest was chosen as a field trip location because it has high micro-diversity and abundance. The DKL was designed to examine the interaction between biotic and abiotic factors as well as the inter-component interactions in the heterogeneous forest. This study employed a qualitative descriptive method utilizing the Analyze, Create, Try, and Reconstruct framework. A survey of the forest locations served as the basis for developing the DKL. The design of the DKL was informed by the survey results and analyzed using the Novak-Gowin Vee Diagram rubric. A trial was conducted to assess the suitability of the DKL in real field conditions. The results of this trial were then analyzed, leading to a reconstruction of the DKL based on challenges encountered during the trial. The reconstruction process included refining the tools used, preparing more structured activity steps, and developing more comprehensive practicum questions. This research has implications for the development of higher-quality and more effective field trip DKLs, ultimately aimed at improving students' science process skills and critical thinking abilities.

Teacher and student perception of integrated science literacy in information, technology, and environtment

Idah Hamidah — 2025-01-30

The development of technology and information in the 21st century is increasing rapidly. Meanwhile, Indonesia's science literacy levels remain categorized as low. Science literacy is among the most essential skills in the 21st century, so integrated technology, information, and environment are fundamental. This research aims to understand the perception of teachers and students towards science literacy integrated with technology, information, and environmental literacy in Junior High Schools (SMP). This research falls under the quantitative category and employs an observational descriptive design. The sample in this study consists of three junior high schools in the Indramayu Regency, representing the Indramayu region's western, central, and eastern regions. The questionnaire instrument determines students' science literacy ability towards information, technology, and the environment. Meanwhile, interviews were used to determine teachers' and students' perceptions of information-based science literacy, technology, and the environment. The research data were obtained using both questionnaires and interview instruments. The study results reveal that the integration of science literacy with information, technology, and the environment achieved percentages of 69.42% for information-integrated science literacy, 70.98% for technology-integrated science literacy, and 73.89% for environment-integrated science literacy, highlighting varying levels of proficiency across these domains. This indicates a moderate ability to integrate science literacy effectively.

The application of chunking technique combined with writing is thinking to improve the communication skills

Sirniawan — 2025-01-30

The student's cognitive load is high, and the level of thinking and communication skills is low. So, the chunking technique combined with writing thinking is implemented. The purpose of this study was to determine the difference in communication skills of students of circulatory system material taught with chunking techniques combined with writing is thinking, chunking techniques, and lecture techniques in class XI students of SMA Negeri 20 Gowa in the 2024/2025 school year. This type of research includes experiments in the form of a pretest, posttest, and nonequivalent control group design. Sampling technique with purposive sampling with specific consideration in the form of almost the same initial ability of students from three treatment classes where class XI. 1 (experimental class), XI.2 (positive control class), and XI.3 (negative control class), each of which totaled 30 students. Data acquisition using non-test instruments to see students' communication skills and teaching module implementation sheet. Hypothesis testing uses the Anacova test because the data is normally distributed and homogeneous. The results of hypothesis testing showed that the significance value was <0.000. This shows the sig value < α (0.05), so it can be concluded that H₀ is rejected and H₁ is accepted. This means that there are differences in the communication skills of students who are taught with chunking techniques combined with writing thinking (experimental class), chunking techniques (positive control class), and lecture techniques (negative control class) on human circulatory system material.

The effect of project-based learning on improving students' science learning outcomes to privat school

Nurtuana Harahap — 2025-01-30

There is still a lack of creativity and innovation in teachers when selecting learning models, so students are less active in learning, and their learning outcomes are low. This study aims to analyze the project-based learning model on the science learning outcomes of students at private junior high school Bhayangkari 3 Rantauprapat in the 2024/2025 academic year. The research design used in this study is an experimental research type with the One-Group Pretest-Posttest model. Before administering treatment, a pretest is conducted to assess the group's initial stability and condition, ensuring clarity before proceeding with the intervention. After the clarity of the group's condition can be seen, then treatment is provided using a project-based learning model. The study results showed that the language of students who previously did not understand and were less active in the learning process became more active. Students can construct their understanding through groups and individuals in learning materials. After using the project-based model, the average value was 75,00, while the conventional one was 67,411. This shows a positive influence on science learning outcomes in the application of the project-based model. This also indicates that active learning strategies foster student engagement and improve academic performance.
