Abstract

Telah dilakukan penelitian tentang analisis pergeseran mikro menggunakan serat optik FD 620-10. Hasil yang diperoleh berupa sensitivitas sensor serat optik untuk pengukuran pergeseran mikro. Pergeseran mikro diukur menggunakan metode sensor serat optik ekstrinsik. Susunan sistem sensor serat optik terdiri dari serat optik produksi autonics tipe FD 620-10, laser dioda dengan λ=650 nm, dan fotodetektor OPT101. Sensitivitas tertinggi berada pada jarak 1 mm sampai 2 mm yakni sebesar 2,506. Maksimum pengukuran pergeseran mikro yang dapat dipakai adalah 3 mm.   Kata kunci: sensor serat optik, sensitivitas, pergeseran mikro

Abstract

The 21stcentury learning trend with mobile devices has made significant impacts on the educational setting. It promotes students? autonomous learning attitude to have their own learning setting anytime, anywhere, and in any way as the purpose of lifelong learning. It is also applied to build students? 21stcentury skills known as 4-Cs; collaboration, communication, critical thinking, and creativity as well as digital literacy. On the other hand, there are some questions and concerns being echoed around the matter of balancing pedagogy and technology on the grammar learning content for university level students. This article is a part of developmental research that focuses on an analysis of the principles and features of mobile technology support tools for learning English grammar in higher education. A questionnaire using online Google form is administered to the 79 students to see their perspective on learning grammar in 21stcentury mode. Further, the data are gathered in qualitative-descriptive method to find the appropriate criteria. This study meets a basic model preference to build a MALL-Based educational app that can support English grammar learning in Universitas Negeri Padang.  It can be concluded that the MALL for grammar should cover all teaching-learning elements like sources and assessments.
