Abstract

Problems in learning science become important notes for teachers because there are still many students who are constrained in understanding the material. Constructive science material is a challenge for teachers to present good learning. One solution that can be used to build or understand the concept of science is with the help of technology. The technology that is starting to develop in the world of education today is augmented reality (AR). The purpose of the literature review is to review the use and utilization of AR technology on the success of learning in the classroom. The literature review method is based on the analytical method by processing the information contained in the literature. The data collected is in the form of qualitative data which is then described in the form of an in-depth explanation. The results of the analysis show that the form of AR development in the world of education uses more marker-based tracking models. The test results of several studies show that the use of AR technology has a positive effect on learning success. However, the effect of AR has so far only been tested on students' learning attitudes and low-level abilities. There is still little testing on the high-level abilities of students.

Abstract

Pesatnya perkembangan teknologi dan penggunaan peralatan elektronik menyebabkan makhluk hidup terkena radiasi medan magnet Extremely Low Frequency (ELF) baik secara sadar atau tidak. Medan magnet ELF adalah radiasi non-pengion dan non-termal. Efek paparan medan ELF mulai dikaji dampaknya terhadap manusia, hewan, dan tumbuhan. Oleh karena itu, penelitian yang menilai efek paparan medan magnet ELF muncul, salah satunya sebagai teknologi pengawetan makanan dan pemrosesan produk fermentasi. Produk pengolahan susu yang sedang diminati oleh masyarakat adalah keju. Bagi orang yang memiliki alergen susu sapi, tidak bisa menikmati keju. Peneliti menginovasi produk keju dari kacang tanah. Pada proses pembuatan keju, sangat dipengaruhi oleh nilai pH dan kadar air agar mendapatkan keju yang terbaik. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh besaran paparan medan magnet ELF dalam proses pembuatan cream cheese kacang tanah. Penelitian ini bersifat eksperimental. Desain penelitian yang digunakan adalah randomized post-test only control group. Dari hasil penelitian ini menunjukkan bahwa nilai pH akan semakin meningkat seiring bertambahnya intensitas paparan medan magnet ELF yang diberikan. Nilai pH paling efektif pada paparan medan magnet 0,1mT dan 0,2mT yaitu 5,37 dan 5,47. Nilai kadar air akan semakin meningkat seiring bertambahnya intensitas paparan medan magnet yang diberikan. Hal ini dikarenakan semakin kecil paparan medan magnet ELF yang diberikan, bakteri Lactobacillus bulgaricu dan Streptococcus lactis dalam proses pembuatan krim keju semakin banyak sehingga nilai pH dan nilai kadar airnya juga semakin kecil.
