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

Educational media serve as a supporting component in learning, offering benefits to enhance student engagement, interactivity, and interest in learning. The media employed should align with current advancements in science and technology, one of which is Augmented Reality (3D), a medium capable of projecting virtual objects into reality. This study aims to 1) Produce an AR media design for high school geography education on atmospheric topics, 2) Determine the feasibility of using AR-based media for such geography education. The creation of the Augmented Reality (3D) educational media utilizes the Borg and Gall (1989) model, which comprises ten development steps. This media creation employs Unity 3D software and supporting applications such as Vuforia, Cinema 4D, and Corel Draw. The development of this educational media resulted in two products: a smartphone application (for Android and iOS) named Cloud AR and its accompanying book, both of which meet UNESCO standards. Based on the research findings, the developed educational media is deemed suitable for use, with a score of 85.16% and classified in the suitable category.

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.
