Abstract

Natural science education (IPA) is an integral part of the education curriculum that aims to introduce students to scientific concepts, develop problem-solving skills, and improve their understanding of natural phenomena. The use of YouTube video-based science learning media has great potential in improving the effectiveness of science learning. By stimulating student engagement, strengthening visual understanding, providing accessibility and flexibility, and increasing learning motivation, YouTube video-based science learning media can be a powerful tool in achieving better learning outcomes at the secondary education level. This research uses a quantitative research approach. This type of research uses Quasi-experimental Design research. Quasi experimental Design, while the research design is Non equivalent Control Group Design. that there is a difference in learning outcomes between the control class and the experimental class with a significant value of 0.021 <0.05 which means H0 is rejected and H1 is accepted. The results of this study concluded that there was an effect of using Youtube video-based science learning media on the learning outcomes of 8th grade students. Continue to integrate the use of YouTube videos in teaching methods and always carry out regular monitoring and evaluation of the impact to ensure that learning objectives are achieved optimally.

Abstract

Abelmoschus esculentus L., commonly known as okra, is a flowering plant belonging to the Malvaceae family. Okra is a versatile plant due to the various uses of its fresh leaves, buds, flowers, pods, stems, and seeds. Okra is a popular health food because of its high content of fiber, vitamin C, and folate, as well as being a good source of calcium and potassium. Additionally, this plant has been used medicinally in the treatment of several disorders, demonstrating anti-cancer, antimicrobial, hypoglycemic, and anti-ulcer activities. Okra is a vegetable crop with diverse nutritional qualities and potential health benefits. This plant is also known to be high in antioxidants. The purpose of this research is to investigate bioactivities such as antioxidant, anti-cancer, antibacterial, and antidiabetic activities, as well as to determine the benefits of okra.

Abstract

This educational process does not only focus on knowledge transfer; it also develops a wide range of individual potential, including academic abilities, relationships, talents, aptitudes, physical abilities, and the arts. Progressivism education is essential to the understanding and implementation of true education in Indonesia. Progressivism education educates students to face and solve problems in social life. This shows how important education is to produce people who are beneficial to society and the country (Sulkifly, 2020). This research uses a quantitative approach and is classified as quantitative descriptive research. This research method is conducted by collecting numerical data. This process of collecting and analyzing data is known as research design or research design. This indicates that the research includes planning and conducting it. The design starts with observing and evaluating known research until further evidence is needed. In the research design, a pre-test and post-test control group was used. This test is done with pearson correlation or by comparing r count with r table. Data validity can be seen if rcount> rtable with 5%. If rtable < rcount then it is said to be valid. The results of the T table test show that the t count obtained is 14.450 has a significance value of 0.000, which indicates that the seventh grade science subject matter has a significant effect on improving students' critical thinking skills. Based on the results of hypothesis testing, F table obtained 208.806 or greater than F table (208.806 greater than 4.351).

Abstract

In Indonesia, environmental pollution is a major concern, especially in industrialised and urban areas. The use of synthesised microorganisms can be an innovative solution to rehabilitate the damaged ecosystems in this region. In this research, an innovative approach based on synthetic biological engineering will be developed to create microbes that have an optimal capacity to absorb and decompose various types of environmental pollutants, such as heavy metals (Pb and Hg), hydrocarbons (benzene), and organic waste (phenol). The results show that the engineered bacteria Escherichia coli, Pseudomonas putida, Bacillus subtilis, and Alcaligenes eutrophus showed high pollutant removal efficiency (85-93%) under laboratory conditions. These results support the potential of synthetic biology technology as an innovative solutions in bioremediation of polluted environments. This research makes a real contribution to green technology innovation in environmental pollution mitigation, supporting the implementation of Sustainable Development Goals (SDGs), especially on points 6 (Clean Water) and 15 (Land Ecosystems).

Abstract

Rapid industrial growth has significantly contributed to environmental pollution, particularly through hazardous waste disposal. Industrial waste, including heavy metals and toxic organic compounds, poses a major challenge for sustainable environmental management. Improper management of this waste can lead to contamination of water, soil, and air, threatening human health and ecosystems (Bagaskara, 2023; Supraptini, 2002). This study investigates the potential of bioremediation using microbes for industrial waste management and identifies factors influencing its effectiveness. Conducted as an experimental laboratory study, the research tests various microorganisms known for their bioremediation capabilities, such as Pseudomonas, Bacillus, and Aspergillus.Analysis of contaminated soil revealed lead (Pb) levels at 63.1 mg/kg, exceeding the livestock toxic limit of 10–30 mg/kg. The growth index (GI) for the inoculum treatment increased by 84.3% to 136.7% over a sixty-day incubation period, while the control treatment showed minimal changes (88.8% to 111.7%). These findings indicate that optimal incubation conditions and appropriate microbial selection can enhance soil quality, making it safer for plant growth and less harmful to the environment. Expanding bioremediation practices could significantly mitigate the adverse effects of industrial waste on environmental pollution. Overall, this research highlights the viability of microbial bioremediation as an effective strategy for managing industrial waste and improving ecological health.
