Abstract

Methylene blue adsorption research has been carried out using activated charcoal from Curculigo latifolia. This research aims to determine the characteristics of the Curculigo latifolia activated charcoal made and the optimum conditions for the adsorption of methylene blue by Curculigo latifolia activated charcoal. Physically activated charcoal is made from Curculigo latifolia which is carbonized at 400°C for 30 minutes, then the physically activated charcoal is soaked in 0.5 M H2SO4 solution for 24 hours to produce chemically activated charcoal. The results showed that the optimum pH for methylene blue adsorption obtained from the Curculigo latifolia activated charcoal adsorbent was physically activated at pH 7 and chemically activated at pH 9. The optimum contact time obtained from the physically and chemically activated Curculigo latifolia activated charcoal adsorbent occurred at a contact time of 15 minutes and 30 minutes. Adsorption of methylene blue by chemically activated Curculigo latifolia activated charcoal follows the Langmuir adsorption isotherm while physically activated charcoal follows the Freundlich adsorption isotherm. The optimum adsorbent mass of physically and chemically activated charcoal is 0.2 g and 0.25 g.

Abstract

Abstrak: Program pendidikan saat ini dirancang untuk membangun kompetensi abad ke-21, dengan salah satu pendekatannya adalah pelatihan keterampilan argumentasi untuk mempertajam kemampuan berpikir kritis. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana model pembelajaran Argument-Driven Inquiry (ADI) memengaruhi kemampuan siswa dalam membuat argumen. Penelitian ini menggunakan desain eksperimen semu dengan tipe static group comparison design. Hasil uji independent t-test menunjukan nilai sig. sebesar 0,001 lebih kecil dari 0,05 yang mengindikasikan adanya perbedaan signifikan antara rata-rata hasil test argumentasi pada kelas eksperimen dan kelas kontrol. Temuan tersebut menunjukan bahwa model pembelajaran ADI secara signifikan memengaruhi kemampuan argumentasi siswa pada materi laju reaksi.Abstract: The current education program is designed to develop 21st-century skills, with one approach being the training of argumentation skills to sharpen critical thingking skills. The purpose of this research is to find out how the Argument-Driven Inquiry (ADI) learning model affects students ability to make arguments. This research uses a quasi experimental design with a static group comparison design type. The results of the independent t-test showed a sig. value of 0.001 smaller than 0.05 which indicated a significant difference between the average argumentation test result in the experimental and control classes. These findings indicate that the ADI learning model significantly impacts students argumentation skills.

Abstract

Current technological developments provide many changes, especially in the field of education. The development of technology requires humans to be able to adapt to life in this era. One of them is by utilizing artificial intelligence (AI) in chemistry learning to open the way to a new era in chemistry education. Literature review was carried out using the narrative literature review method to identify the role of AI in chemistry learning in improving 21st century skills. The application of AI in chemistry learning not only has a positive impact on 21st century skills, but also changes the way students interact with chemistry concepts and opens up new opportunities for students to understand chemistry concepts in more depth through enhanced learning media, interactive simulations, and predictions accurate. The application of AI has been widely applied in chemistry learning and has shown positive results in improving 21st century skills.
