Abstract

Indonesia is the second largest contributor of plastic waste in the world with an unmanageable capacity of 3.2 million tonnes each year and 1.29 million tonnes of plastic waste ending up in the ocean. Plastic waste accounted for 16% of the world's marine plastic pollution, which directly contributed greenhouse gas emissions and climate change. Pyrolysis was an effective solution to overcome the processing of plastic waste which produces energy conversion. Pyrolysis is the process of breaking down long chain polymer molecules into smaller molecules through thermal cracking in the absence of oxygen at temperatures above 400°C. Pyrolysis does not release pollutants in the form of particles and CO2 into the atmosphere so it practically does not disturb the environment. This research method was a pyrolysis experiment on Polyethylene terephthalate (PET) plastic waste from mineral water packaging and metal-coated PET (metallized PET foil) from milk and snack packaging. The pyrolysis product was liquid oil with two different types of colors whose compounds were identified using gas chromatography – mass spectrometry (GC-MS). The number of compound components from PET plastic waste pyrolysis products was 58 components with the largest compound component areas being 5-methyl-1-heptene and 1-tridecanol. Meanwhile, the number of compound components from the pyrolysis product of metal-coated PET plastic waste (metallized PET foil) was 56 compound components with the largest compound component areas being 3-methyl-5-undecene and 1-tridecanol.

Abstract

The aim of this research was to analyze the needs of students in science learning at MTsN 1 Seluma, Bengkulu. The method used was a survey via questionnaire with 9 questions given to 30 class VII students. The survey results show that 100% of students have textbooks/handbooks, 100% have smartphones, 93% have difficulty studying material that only comes from books, so 100% of students look for other materials besides books from school to help understand the material. science via the internet, therefore 100% of students need interesting alternative learning media. In science learning, students agree that there is Android-based learning media for science material, especially environmental pollution material. Students want learning to be adapted to current developments and technology, interesting, interactive, and can be accessed anytime and anywhere via smartphone. Implementation of media in the form of Android-based applications can be an alternative to empower students' use of technology and to improve the quality of science learning.

Abstract

The acid base indicators commonly used by scientists are mostly synthetic indicators that are harmful for the environment.Moreover, chemists need various chemicals to detect broad pH ranges for acid and base samples solution.  The aim of this research was to create a natural universal pH indicator from telang flower (Clitoria ternatea L.) extract coupled with the digital image detection. The universal pH indicator is very important in education chemistry that broadly used for titration and other class room chemical experiments. This process of making a natural universal pH indicator integrated with digital images meets green chemistry criteria that use environmentally friendly materials and technology. The results show that color absorption data at pH 1-2 are purple, pH 3-5 are violet, pH 6-10 are blue, pH 11-12 are green and pH 13-14 are yellow. RGB intensity digital image data shows the intensity of the red color increases in the pH range 6-11, while the intensity of the green and blue colors tends to be stable. The proposed method was validated using a UV-Vis spectrophotometer and conventional pH meter that give the comparable results.

Abstract

The bark of the traditional plant, Archidendron bubalinum, known locally as kabau, exhibits promising qualities as a natural antibacterial agent. This research was conducted with two main objectives: (1) to evaluate the antibacterial efficacy of kabau fruit peel extract against two common pathogenic bacteria, Staphylococcus aureus and Escherichia coli, and (2) to design, validate, and assess the effectiveness of a research-based Microbiology E-Module in fostering students' critical analytical skills. The antibacterial capacity was tested using the paper disc diffusion method across a range of extract concentrations (5%, 10%, 20%, 40%, and 80%), using both pure water (aquades) and 2% dimethyl sulfoxide as carriers. Statistical analysis (one-way ANOVA, p = 0.020 < 0.05) indicated a notable difference in the zone of inhibition diameter across the various concentrations. The most potent antibacterial effect was observed at the 80% concentration with the aquades solvent, yielding inhibition zones of 3.97 mm against S. aureus and 8.42 mm against E. coli. These empirical results served as the core content for the innovative E-Module. The developed E-Module attained a high level of validity, achieving a CVR score of 1.00 from 5 expert validators, thus confirming its readiness for use. Subsequent evaluation during instructional application revealed a marked elevation in students' critical thinking abilities. Students in the Biology Department at FMIPA, Universitas Bengkulu, showed an initial mean pre-test score of 41.67, which surged to 88.00 in the post-test. This change resulted in an N-gain score of 0.79, positioning the improvement in the "high" category. Therefore, A. bubalinum extract is confirmed to hold antibacterial potential, and the E-Module is proven to be an effective educational tool for enhancing students' critical thinking competence.
