Abstract

Makanan yang beredar dibeberapa wilayah di Jawa Barat diduga mengandung Bahan Tambahan Pangan (BTP) yang berbahaya. Zat aditif pada makanan digunakan untuk mempertahankan kualitas suatu zat pangan. Penelitian ini dilakukan untuk mengetahui pengetahuan masyarakat mengenai fungsi dan bahaya yang ditimbulkan oleh penggunaan zat aditif. Metode yang digunakan adalah observasi dan survei lapangan dengan teknik ceramah, tanya jawab, demonstrasi, dan penyebaran angket dengan beberapa sasaran di wilayah di Jawa Barat dengan subjek penelitian yaitu remaja dan ibu-ibu. Hasil penyebaran angket menunjukkan bahwa sebagian masyarakat ada yang masih keliru dalam memahami fungsi penggunaan zat aditif sehingga perlu adanya tindak lanjut masyarakat yang mulai membiasakan diri untuk memilah dan memilih jajanan yang sehat dengan memperhatikan kondisi fisik makanan. Masyarakat juga mulai terbiasa untuk menggunakan zat aditif alami dibandingkan zat aditif buatan karena lebih terjamin kualitas dan kesehatannya bagi tubuh.

Abstract

This study aims to analyze the media's validation test results and describe the appearance of the PuzzleRedox game media on oxidation-reduction (redox) reaction material. The research method used is Design-Based Research. The appearance of the media is described by making a flowchart and storyboard. Flowcharts and Storyboards contain the stages of making PuzzleRedox media, including media design, media components, andrules for using PuzzleRedox media. The media will then be tested for validity on 3 expert validators, namely media experts, material experts, and learning experts. The validator is a chemistry education lecturer at UIN Sunan Gunung Djati and a Chemistry teacher at SMA Pasundan Cikalongkulon. Based on the validity test results, the mean value of r count was 0.859, higher than the critical value of 0.30. Therefore, the game media PuzzleRedox on the oxidation-reduction (redox) reaction material is declared valid and can be used as a medium or aids in the learning process.

Abstract

This research aims to analyze the improvement in student learning outcomes in the application of the problem-solving-based electron configuration e-module. The true-experiment method with a pretest-posttest design was used in this research so that learning outcomes from the control class and the experimental class could be compared. The research results show that during the process of implementing the e-module, student activities went very well. At the stages of analyzing problems, making hypotheses, collecting data, testing hypotheses, and making conclusions respectively, students got an average score of 84.25; 82.5; 80.5; 100; and 89.5. The statistical test of student learning outcomes in the control class and experimental class using the Mann-Withney U test shows a significance value of 0.013 so it can be concluded that there is a significant difference between student learning outcomes with the application of e-modules and without the application of e-modules in learning.

Abstract

Scientific explanation is an essential skill in chemistry learning because it connects scientific principles and objective evidence. This study aims to describe the application of guided inquiry-based learning in thin-layer chromatography experiments of synthetic and natural food coloring to develop students' scientific explanations in learning applications. This study used a pre-experimental method with a post-test only one-shot case study design. In the implementation of learning, the implementation rate reached 87%. The average scores for worksheets and scientific explanation tests were 78 and 79, respectively. This indicates that the application of guided inquiry-based worksheets through TLC experiments is practical in developing students' scientific explanation skills. This experiment can be adopted in broader chemistry learning contexts by integrating guided inquiry with thin-layer chromatography using real food colorants, thereby fostering scientific thinking and providing students with hands-on experience that emphasizes the relevance of chemistry in everyday life.

Abstract

The research aims to determine the effect of learning style on students’ performance through online learning during the Covid-19 pandemic. The subjects of study are 269 chemistry education students at three universities in Indonesia. The data collection of learning style uses a Likert scale questionnaire, and learning performance is obtained from students’ grade point average. In this research, students’ learning style was divided into visual, auditorial, and kinesthetic. Data were analyzed using descriptive statistics with linear regression and ANOVA tests. The learning styles positively affect student learning performance by 4.7%, while 95.3% of other factors are not examined in this study. The learning performance of students with auditory is higher than visual and kinesthetic learning styles. Based on the inferential analysis, there is no significant difference in student learning performance based on student learning styles. Therefore, students with different learning styles have the same learning performance in online learning.

Abstract

This study aims to describe the learning process and analyze the development of students' scientific performance through the application of project-based worksheets in making hand cream from black rice kefir (Oryza sativa L.indica), as well as analyzing the characteristics of the hand cream products produced. The research was conducted at SMK MVP ARS International Bandung in class XI Pharmacy. The research approach used was quantitative with pre-experimental method and one shot case study design. The results showed that students' activities in the learning process reached a score of 93 and scientific performance obtained an average score of 89, both in the very good category. Product characterization showed that all formulations of hand cream from black rice kefir (Oryza sativa L.indica) met SNI standards with excellent quality based on pH, organoleptic, irritation, homogeneity, spreadability, and emulsion type parameters, and obtained a product assessment with an average score of 96. The LC50 value obtained from the antioxidant test results was 90.5500 (Strong). These findings indicate that the application of project-based worksheets is effective in developing students' scientific performance while producing quality products.

Abstract

This study aims to describe the application of science process skills-based worksheets in the project of making larvicides from areca nut extract on the cognitive and psychomotor aspects of students, as well as to determine the effectiveness of areca nut extract as a larvicide. This research raised the issue of using synthetic larvicides as learning facilitated by science process skills-based worksheets. The larvicide was divided into six concentration variations. This study used a pre-experiment method with a one-shot study case design involving one experimental class, without a pretest or control class. The subjects used in this study were 36 10th grade students of MAN 2 Bandung City. Data collection used instruments in the form of science process skills-based worksheets, observation sheets, performance assessment sheets, and presentation assessment sheets. Data analysis of science process skills was done with a Likert scale assessment. The cognitive aspect of the science process skills worksheet obtained an average score of 82, with a very good interpretation, while the psychomotor aspect of students was 83, which showed a very good interpretation. It can be concluded that the use of science process skills-based worksheets can help in cognitive skills and psychomotor skills. In the larvicide making project, effective results were obtained at a concentration of 9 mL with a percentage of mosquito larvae death of 100%.
