Abstract

This study was motivated by the limited support of engaging media in chemistry learning on molecular shape materials. The material of molecular shape is abstract and requires a medium capable of visualizing the molecular shape clearly and realistically. The technology that aligns with these problems is Augmented Reality. This research aims to observe the validity results of the developed product and to know the student's responses towards the Augmented Reality (AR) Based Chemistry E-book on Molecular Shape Material. This study is an R&D (Research and Development) development study. By using the 4-D development model that was modified into 3 stages; define, design, develop. The validation test of this media is based on assessments from language experts, media experts, and material experts. The product validation results were assessed by media experts by 97%, material experts by 94%, and language experts by 90%, with a very valid category. In addition, a trial was conducted on students to find out the response to the developed media. Based on the assessment results of student responses, a percentage of 89% was obtained on a small scale and 95% on a medium scale with a very good category

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh warna filter terhadap intensitas cahaya yang diteruskan dari sumber cahaya lampu LED serta menentukan tingkat transmisi dan peredaman cahaya pada berbagai jarak antara sumber dan sensor. Penelitian ini menggunakan metode eksperimen langsung dengan pengukuran intensitas cahaya menggunakan aplikasi Lux Meter pada jarak 20 cm, 30 cm, dan 40 cm. Variasi filter warna yang digunakan meliputi kuning, oranye, hijau, merah, dan biru, serta kondisi tanpa filter sebagai pembanding. Hasil penelitian menunjukkan bahwa warna filter berpengaruh nyata terhadap intensitas cahaya yang diteruskan. Rata-rata intensitas cahaya yang diperoleh yaitu tanpa filter 168 lux, kuning 131,3 lux, oranye 78,3 lux, merah 83,3 lux, biru 65,3 lux, dan hijau 39 lux. Filter kuning memiliki transmisi cahaya tertinggi, sedangkan filter hijau menunjukkan tingkat peredaman paling besar. Selain itu, intensitas cahaya menurun seiring bertambahnya jarak sumber terhadap sensor, sesuai dengan Hukum Kuadrat Terbalik (Inverse Square Law). Dengan demikian, penelitian ini membuktikan bahwa perbedaan warna filter secara signifikan memengaruhi kemampuan transmisi dan peredaman cahaya dari sumber LED.

Abstract

This study aimed to investigate the level of scientific literacy and Nature of Science (NOS) conceptions among pre-service chemistry teachers in the context of environmental issues. This study adopted a mixed-methods approach combining descriptive surveys and semi-structured interviews. Participants were 72 pre-service chemistry teachers from universities in Palembang, Indonesia, selected through purposive sampling across academic levels. Data collection involved three instruments: a scientific literacy test on environmental issues, a NOS perception questionnaire, and qualitative interviews. The results showed that scientific literacy among participants was generally at a high level, with an average score of 86.00. Participants demonstrated strong competence in scientific content and practices, particularly on renewable energy, deforestation, and air pollution. However, lower scores were observed in contextual understanding, such as water quality and waste management. Regarding NOS conceptions, participants obtained an average score of 72.88%, indicating a high level of understanding, particularly on the tentativeness of scientific knowledge and the role of observation and inference. However, misunderstandings persist in areas such as creativity in science and the influence of social and cultural values. Interview results revealed a nuanced understanding of NOS, which is in line with theoretical frameworks that view science as empirical, tentative, and influenced by human creativity and social context. These insights underscore the importance of integrating NOS into science teacher education to foster critical thinking and contextual teaching of environmental issues
