Abstract

Minyak goreng merupakan salah satu bahan pangan yang dimanfaatkan untuk mematangkan bahan pangan. Mengkonsumsi minyak jelantah dapat menyebabkan berbagai masalah kesehatan, misalnya kerusakan pada organ-organ bagian dalam tubuh. Dalam penelitian ini, telah diteliti proses permurnian minyak jelantah dengan mengukur kadar asam lemak (FFA) dan massa jenis minyak jelantah yang telah dijernihkan. Analisa Asam Lemak Bebas (FFA) dilakukan dengan metode Oil Pipette Titration (OPT), yaitu metode titrasi sederhana menggunakan pipet. Selain itu, dilakukan pengukuran massa jenis menggunakan piknometer sederhana. Penelitian ini menunjukkan jumlah FFA yang lebih tinggi dari maksimum 0,3% yang direkomendasikan dalam SNI 7709-2019. Dengan perlakuan terhadap minyak jelantah dengan berbagai massa sekam padi dan waktu perendaman, kandungan FFA ditemukan menurun secara signifikan. Berdasarkan 200 mL sampel minyak jelantah yang dianalisis, massa sekam padi yang efektif dalam menurunkan FFA selama 72 jam adalah 20 gr, dengan penurunan persentase kadar FFA sebesar 0,23%. Temuan dari penelitian ini mendukung potensi penggunaan adsorben sekam padi untuk mengurangi asam lemak bebas dalam minyak jelantah.

Abstract

In the 21st century, technological development has entered all aspects of life, including education. With its global potential, technology digitizes education, requiring teachers to use technology through media such as augmented reality (AR). This study aims to determine the readiness of physics teachers in Indonesia to implement AR-based learning. More specifically, this research explores the extent to which physics teachers are prepared based on aspects of alignment, capability, and engagement (ACE) in implementing AR-based learning. This exploratory research is conducted by distributing questionnaires with ACE aspects. This study involved several junior and senior high school physics teachers. Data analysis techniques use KH coder and quantitative descriptive. The results show that teachers already know the definition, features, and benefits of AR in learning (alignment aspect). Still, only a minority of teachers have implemented AR-based learning (capability aspect). In the engagement aspect, it is known that teachers want to learn more about how to create AR and implement AR effectively. The implications of this research are recommendations to stakeholders to encourage and facilitate teachers, especially physics teachers.

Abstract

Many countries are revitalizing science subjects by strengthening the integration of science content with engineering, technology, and mathematics content and skills, creating STEM learning. However, the availability of textbooks capable of facilitating this integration remains limited. This study aims to analyze the Science and Engineering Practice content in high school physics textbooks used by Indonesian and Malaysian schools. This study is qualitative descriptive research with content analysis. The analysis was conducted on two samples of Indonesian and Malaysian books each. Content analysis is based on the SEPAR (Science and Engineering Practice Assessment Rubric) that divides Science and Engineering Practice into 8 elements. The analysis showed that Indonesian textbooks' Science and Engineering Practice content is still lacking compared to Malaysian books in all elements. The most common aspects found in Indonesian books are asking questions and defining problems. These results show that Malaysian high school physics textbooks represent many elements of Science and Engineering Practices, but there are still several elements that are not optimal. This research highlights the importance of improving the representation of  Science and Engineering Practice in Physics textbook.
