Abstract

The purpose of this study was to describe the effect of POE (Predict, Observe, and Explain) learning model on: 1) self efficacy, 2) student learning outcomes, and 3) self efficacy and student learning outcomes on basic laws of chemistry. This study used a quantitative approach with an experimental design of the quasi-experiment type, and with a non-equivalent control group design. The population in this study were class X students of SMAN 1 Ngunut, while the samples were class X-E as the experimental class and class X-F as the control class with the sampling technique was purposive sampling. The research instrument in the form of a questionnaire was used to measure student self-efficacy and test questions were used to measure student learning outcomes. Data analysis used prerequisite tests (normality test and homogeneity test), and hypothesis tests use independent sample t-test and manova test. The results showed that: 1) there is an effect of the POE learning model on self-efficacy with a sig value. (2-tailed) 0.000 <0.05, 2) there is an effect of the POE learning model on student learning outcomes with a sig value. (2-tailed) 0.000 <0.05, and 3) there is an effect of the POE learning model on self efficacy and student learning outcomes on the material of basic laws of chemistry with a sig value. (2-tailed) 0.000 <0.05.

Abstract

This study explores the contextual integration of Islamic values within science education through the "Islam and Science Integration" course in an Islamic higher education institution. Using a qualitative case study approach, the research involved five students from the Physics Education Study Program at Universitas Islam Negeri Antasari Banjarmasin. Data were collected through interviews and documentation, and analyzed using data reduction, data display, and conclusion drawing. The findings reveal that students demonstrate Islamic integration by applying fiqh principles to contemporary scientific and technological issues. However, integrating Islamic values with science does not override fiqh rulings rooted in the Qur'an and Sunnah. Instead, this integration enriches students' contextual understanding of religion and science. The study concludes that the value of Islamic integration in science education is best reflected in the fiqh framework, offering a meaningful model for harmonizing religious understanding with scientific reasoning. This research contributes to developing context-based Islamic science education in higher education.

Abstract

Perkembangan pesat kecerdasan buatan (AI) generatif telah menghadirkan tantangan etika yang signifikan dalam kerangka etika ilmiah dan filsafat moral. Meningkatnya ketergantungan pada keluaran yang dihasilkan AI menimbulkan kekhawatiran mengenai tanggung jawab moral, bias epistemik, dan batasan antara penalaran manusia dan kecerdasan mesin. Studi ini bertujuan untuk meneliti keterbatasan etika pemanfaatan AI melalui perspektif etika ilmiah dan filsafat moral. Metode tinjauan naratif digunakan untuk mensintesis literatur yang relevan tentang isu-isu etika dan filosofis seputar AI generatif. Data dikumpulkan melalui pencarian sistematis di basis data Scopus dan Google Scholar menggunakan kata kunci yang terkait dengan etika AI, filsafat moral, dan AI generatif. Proses tinjauan mengidentifikasi 12 artikel yang ditinjau sejawat yang secara eksplisit membahas kerangka kerja moral-filosofis dalam penerapan AI generatif. Temuan menunjukkan bahwa filsafat moral berfungsi sebagai batasan etika kritis dalam membimbing penggunaan AI yang bertanggung jawab, khususnya dalam meminimalkan bias kognitif dan mencegah penggantian penilaian manusia secara tidak kritis dengan keluaran algoritmik. Hasil penelitian lebih lanjut menunjukkan bahwa kendala etika tidak muncul dari keterbatasan teknologi AI itu sendiri, tetapi dari nilai-nilai moral yang berkembang yang mengatur adopsinya secara luas. Integrasi filsafat moral ke dalam tata kelola AI berkontribusi pada penyeimbangan kemajuan teknologi dengan penalaran etis yang berpusat pada manusia. Studi ini menyiratkan bahwa kerangka kerja etis dan filosofis sangat penting dalam mendefinisikan ruang lingkup penggunaan AI generatif yang diperbolehkan dan dalam memperkuat akuntabilitas, keadilan, dan tanggung jawab moral dalam masyarakat digital kontemporer.

Abstract

Higher Order Thinking Skills (HOTS) and Scientific Reasoning Skills (SRS) play a significant role in helping students develop a comprehensive understanding of chemistry concepts. However, studies examining the relationship between HOTS and SRS remain limited. Such studies are essential for providing a theoretical foundation for the development of chemistry instruction in schools. Therefore, this study aims to analyze the relationship between HOTS and SRS in chemistry learning. This study employed a narrative literature review approach, with HOTS and SRS as the focus of the review. Relevant literature was identified through the Google Scholar database, covering publications from 2020 to 2026, using the keywords "higher order thinking skills" OR "scientific reasoning skills" AND "chemistry learning." A total of 27 relevant articles were selected for analysis. The data were analyzed by synthesizing and presenting the findings of previous studies in a narrative and descriptive manner. The review revealed that scientific reasoning skills constitute an essential component of HOTS that students need to develop a meaningful and comprehensive understanding of chemistry concepts. Furthermore, the dimensions of scientific reasoning contribute to the development of students' HOTS, thereby supporting the acquisition of essential twenty-first-century skills.

Abstract

Karet (Hevea brasiliensis) menjadi salah satu komoditas unggulan sektor perkebunan Indonesia. Pemanfaatan karet biasanya hanya difokuskan pada pengambilan getah pohon, sedangkan biji karet tidak mempunyai nilai ekonomis selain sebagai benih generatif pohon karet, sehingga biji karet belum termanfaatkan secara optimal dan dianggap sebagai limbah. Penelitian bertujuan untuk menghasilkan berbagai produk ramah lingkungan dengan mengoptimalisasi biji karet melalui proses biorefinery yaitu biodiesel, briket, dan pupuk organik cair. Proses mengolah biodiesel dari biji karet yaitu dengan mengepres biji karet yang sudah dilepaskan dari cangkangnya, dilanjutkan dengan proses degumming dan reaksi transesterifikasi. Proses tersebut menghasilkan limbah cangkang biji karet dan ampas biji karet. Cangkang biji karet diolah menjadi briket dengan proses pengarangan, pengayakan, pencampuran bahan, pencetakan briket, dan pengeringan. Proses pengolahan ampas biji karet menjadi pupuk cair organik yaitu dengan menambahkan larutan EM4 dan kotoran ayam, kemudian difermentasi selama 3 minggu. Hasil dari penelitian ini yaitu minyak biji karet yang berpotensi menjadi biodiesel, briket, dan pupuk organik

Abstract

Konsep-konsep dalam ilmu kimia bersifat abstrak dan saling berhubungan, seperti konsep asam basa dan hidrolisis garam. Hal ini dimungkinkan apabila pemahaman konsep asam basa siswa rendah maka akan sulit memahami konsep hidrolisis dengan baik. Oleh sebab itu, penelitian ini bertujuan untuk mengetahui pengaruh pemahaman konsep asam basa terhadap konsep hidrolisis garam pada mata pelajaran kimia SMA kelas XI MIPA. Penelitian ini termasuk jenis penelitian korelasi. Teknik pengumpulan data menggunakan tes pemahaman konsep yang terdiri atas 15 soal pilihan ganda berpasangan antara konsep asam basa dan hidrolisis garam. Analisis data menggunakan uji regresi linear. Hasil penelitian menunjukkan bahwa ada pengaruh pemahaman konsep asam basa terhadap pemahaman konsep hidrolisis garam dengan korelasi tergolong kuat. Sebanyak 51,5% pemahaman konsep asam basa mempengaruhi pemahaman konsep hidrolisis garam.
