Abstract

This article reported design of FBG Sensor layered by 2D Graphene Material. In this research, the FBG was coated with single layer graphene material, then the outher FBG has been coated with Aluminium, Chromium Oxide, PMMA, and Silica. The finite element method was used to analyze the profile  of each coated-FBG with a thickness of 20 µm. Furthermore, the sensitivity of each designed coated-FBGs for the temperature measurement was calculated in the range of 25 oC – 300 oC. Design and analysis of coated FBG found that the FBG coated with graphene then layered by PMMA material has the highest sensitivity of 406.4 pm/℃. Although the sensitivity was 395.73pm/℃ for PMMA material. It was followed by Aluminium coating material which yields the sensitivity of 71.367pm/℃. The Silica and Chromium oxide yield the same sensitivity of 13.73pm/℃. Furthermore, the simulation results shows that the design of coated FBGs with a Gaussian apodization has the narrowest FWHM width of 1.3 nm. While the Tanh and Uniform apodization yield FWHM width of 3.724 nm and 3.732 nm respectively. Certainly, the best FBG design for high temperature sensor was proposed by FBGs coated by graphene and layered with PMMA material with Gaussian apodization

Abstract

The low learning outcomes of students physics today are often triggered by the dominance of conventional teacher-centered learning and the limitations of interactive media. The abstract characteristics of renewable energy materials demand visual innovation to stimulate active student engagement. This study aims to analyze the effectiveness of the implementation of Nearpod-based learning media with a deep learning approach in improving the cognitive learning outcomes of high school students, as well as testing the difference in achievement between the experimental class and the control class. This quantitative research applied a quasi-experimental design in the form of a posttest-only control group design. The research population involves all students of class X of SMAN 11 Pekanbaru for the 2025/2026 school year. Through the cluster random sampling technique, class X.3 was selected as the experimental group using Nearpod media, and class X.5 as the control group with conventional models. Cognitive ability data was collected through an objective test instrument in the form of 30 post-treatment multiple-choice questions. Data analysis was carried out statistically descriptive and inferential using the Independent Sample t-Test. The results showed that the average value of cognitive learning outcomes of the experimental group reached 78.89, significantly outperforming the control group which obtained an average of 71.43. Through the hypothesis test, a significance value (2-tailed) of 0.003 (< 0.05) was obtained, which proved that there was a significant difference in academic performance between the two classes. It was concluded that the use of the Nearpod platform with a deep learning approach has proven to be effective in minimizing conceptual obstacles and optimizing the achievement of students' Physics learning outcomes.
