Abstract

The purpose of this study was to examine common misconceptions among elementary school students regarding the greenhouse effect. The method used was descriptive research, using 52 student samples selected by purposive sampling technique, and the Rasch model was used to analyze the data. The results showed that the Rasch Model confirmed the validity of the tool, highlighting the challenges in understanding the concept of the greenhouse effect among bright students. Students had a misconception rate of 63% when analyzing the relationship between the ozone layer and the greenhouse effect, 62% when distinguishing between the greenhouse effect and global warming, 60% when examining the relationship between the greenhouse effect and cow dung waste, and 56% when determining the relationship between the greenhouse effect and acid rain. Effective teaching strategies are essential for correcting misconceptions, and future research should explore media or learning models to address these issues. It is imperative for educators to design targeted interventions that specifically target these prevalent misconceptions to improve science education outcomes among elementary school students in Indonesia.

Abstract

Excessive exposure to solar UV radiation is a major cause of skin photoaging, which is characterized by premature wrinkling, hyperpigmentation, and loss of skin elasticity. Traditional synthetic sunscreens are effective, but their potential side effects have led to a search for natural alternatives. Bombyx mori has attracted attention for its rich composition of bioactive compounds, such as silk proteins, sericin and fibroin, which have antioxidant and anti-inflammatory properties. These components are believed to contribute to the protection of skin cells against oxidative stress and inflammation from UV rays, thereby slowing down the aging process. This review systematically examines recent studies that have investigated the photoprotective effects of Bombyx mori-derived extracts, silk proteins, and other related substances. Findings suggest that these natural agents have the potential to reduce UV damage by enhancing skin defense mechanisms, promoting collagen synthesis, and reducing matrix metalloproteinase expression. In addition, the hypoallergenic properties of Bombyx mori compounds make them suitable for individuals with sensitive skin, thereby expanding their application in the skin care industry. However, while promising, research on Bombyx mori as a sunscreen agent is still in its early stages. Further studies are needed to elucidate the mechanisms underlying their photoprotective effects, assess their long-term safety, and optimize their formulations for effective delivery to the skin. This literature review contributes to a comprehensive understanding of the potential of Bombyx mori as an alternative to natural sunscreens and highlights the need for further research in harnessing its benefits to fight photoaging and maintain healthy skin.

Abstract

This research aims to investigate the influence of the SIRI learning model, namely learning based on integrated problem solving in Indonesian Siri' culture in improving the critical thinking skills of biology students. This experimental research was conducted with a pretest-posttest nonequivalent control group design and involved 109 biology students at Universitas Negeri Makassar, Universitas Pendidikan Mandalika, and Universitas PGRI Sumatera Barat, Indonesia. Data was collected using a critical thinking skills essay test. A critical thinking skills rubric was used to assess student answers and the results were analyzed using ANCOVA at a significance level of 0.05. Research findings show that there is an influence of the SIRI learning model on the critical thinking skills of biology students. The LSD test results show that the critical thinking skills of the SIRI class are significantly different from those of the PBL class and conventional class. It was concluded that the SIRI learning model could improve biology students' critical thinking skills.

Abstract

Flavanoids are one of the many compounds in phenols that can denature bacterial cell membrane proteins, thus inhibiting cell growth. The purpose of this study was to formulate an anti-acne gel for the ethanolic extract of red algae (Eucheuma cottonii) and to test its antimicrobial activity against Propionibacterium acnes. The method used is laboratory research design by making antiacne gel preparations of red algae extract with concentrations of 1%, 3%, 5% and testing the antimicrobial activity with the agar diffusion method using wells on MHA media which is incubated for 1x24 hours. The results of the evaluation of the gel preparation before and after the cycling test met the requirements of organoleptic, homogeneity, pH, viscosity, and dispersibility where each formula was stable in the gel preparation. The results showed that red algae extract (Eucheuma cottonii) could be formulated and was stable in the form of an anti-acne gel and had antibacterial activity. In formula I with a concentration of 1% the inhibition zone formed was 36.33 mm, in formula II with a concentration of 3% the inhibition zone formed was 38.79 mm and in formula III with a concentration of 5% the inhibition zone formed was 34.27 mm. So which has optimal antibacterial activity against Propionibacterium acnes is formula II with a concentration of 3% and an area of ​​inhibition zone of 38.79 mm.

Abstract

Gili Ketapang is an area with quite high fisheries potential, reaching 40% of the resource production in East Java. The catch season is often associated with the presence of plankton as the main source of food availability in marine ecosystems, influenced by season, weather, temperature, and water quality. The aim of this research is to report water quality results and analysis of phytoplankton and zooplankton composition in the coastal waters of Gili Ketapang, East Java. The method used in this research is quantitative descriptive to describe plankton composition and water quality in Gili Ketapang, East Java. In this study, 26 phytoplankton genera and 35 zooplankton genera were found. The abundance of phytoplankton and zooplankton measured in the West Season was lower compared to the abundance in Transition Season I. The phytoplankton and zooplankton diversity index showed moderate diversity (1<H'<3). In general, the results of water quality measurements obtained in the West Season were temperature 32.8 , pH 8.54, dissolved oxygen 6.72 mg/L, salinity 32.66 ppt, Secchi depth 13.11 m, and nitrate 1.39 mg/L. Meanwhile, the water quality in Transition Season I was respectively temperature 30.26 , pH 7.8, dissolved oxygen 8.24 mg/L, salinity 31.47 ppt, Secchi depth 10.92 m, and nitrate 1.21 mg/L.

Abstract

Improving student learning outcomes will always be influenced by how teachers teach and provide innovation in learning. This study focuses on evaluating the cognitive learning achievements of class XI high school physics students in the Optical Instrument material, using the Wordwall-assisted Brain Based Learning model. The study is a quasi-experiment with all students in class XI of MS SMAN Plus Riau Province. A sample of 59 students with class XI MS 1 as the experimental group and class XI MS 4 as the control group. Daily tests were conducted to collect data on cognitive learning outcomes, which were analyzed both descriptively and inferentially. The findings indicate a significant difference in cognitive learning outcomes between the experimental and control groups, with the former achieving an average outcome of 81.83 and the latter attaining an average of 73.10. These results demonstrate that the Wordwall-assisted BBL learning model can enhance the cognitive learning outcomes of grade XI students in Senior High School, specifically in the Optical Equipment material.

Abstract

Culture has an important role in realizing sustainable education. An Ethnochemistry-based Culturally Responsive Teaching Approach has the potential to integrate students' cultural and chemical concepts into classroom learning. However, this approach has not been widely implemented in schools. Therefore, this research aims to determine the effect of implementing an tthnochemistry-based culturally responsive teaching approach on improving cognitive learning outcomes in green chemistry material in high school. A quasi-experimental design involving 36 students in the experimental class and 36 students in the control class was used, utilizing a post-test with ten multiple choice questions to measure cognitive learning outcomes. The Kruskal-Wallis test was then applied to evaluate the effectiveness of the treatment. The research results show that the application of the Culturally Responsive Teaching approach which is integrated with ethnochemistry has an effect on increasing cognitive learning outcomes in green chemistry material.
