Abstract

Argumentation skills and positive attitudes toward physics are important aspects of 21st-century learning, but are still relatively low among Indonesian students. This study aims to improve these two aspects through the application of the Argument Driven Inquiry (ADI) learning model integrated with Islamic science. This study is a Classroom Action Research (CAR) conducted in two cycles on grade XI students of MAN 1 Pekanbaru with harmonic vibration material. The instruments used included attitude questionnaires, argumentation questions, observation sheets, and learning tools. Data were collected through observation and tests. The results showed a significant increase in teacher and student activities, attitudes toward physics, and students' argumentation skills. Learning activities developed from the Good to Very Good category. Attitudes toward physics increased from low to high and very high categories. Argumentation skills, which were initially classified as underdeveloped, became good to very good. These findings indicate that the ADI model integrated with Islamic science is effective in increasing student engagement and the quality of physics learning.

Abstract

This study aims to develop an inclusive learning model based on Problem-Based Learning (PBL) to enhance students’ critical thinking skills and scientific attitudes in the 3T regions (frontier, outermost, and disadvantaged areas) of Riau Province, Indonesia. The research is motivated by the limited access to quality education in 3T areas, which affects students’ higher-order thinking skills and mastery of scientific attitudes. The model was developed using a Research and Development (R&D) approach adapted from the Borg & Gall framework, involving preliminary studies, model design, expert validation, revision, and limited trials. The research subjects were high school students in one of the 3T schools. Instruments used included a critical thinking skills test, a scientific attitude questionnaire, observation sheets, and interview guidelines. The results show that the inclusive PBL model developed is valid, practical, and effective for classroom implementation. Its application successfully improved students’ critical thinking skills through contextual problem-solving activities and fostered scientific attitudes such as curiosity, openness to evidence, and responsibility in the learning process. This study recommends the inclusive PBL model as an alternative instructional strategy for schools in 3T areas to support equitable improvement in education quality.

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 use of Single Mode Fiber Bragg Grating (SMFBG) has been increasing in recent years due to its compact size, low cost, fast response and immunity to electromagnetic interference. It is commonly integrated into medical devices for long-distance light transmission and collection due to its high flexibility, low propagation loss, compatibility and tolerance to electromagnetic interference. SMFBG is a device made of thin glass material that is used as a medium for transmitting information in the form of light signals sourced from lasers or LEDs from one location to another. It consists of 3 main components, namely core with a certain grating, blanket (cladding) and jacket (coating). The advantage of optical fiber is that the data when transmitted is converted into light so as to reduce the risk of data damage. Other advantages include very small size, minimal interference with electromagnetic waves, resistance to temperature changes, attenuation when the transmission process is small enough, and large enough bandwidth. The orientation of this literature review is to understand the concept of optical fiber, the concept of reflection and refraction, and how light propagates in optical fiber.

Abstract

Optical fiber is increasingly popular and appreciated as a modern sensor technology in various sectors, one of which is for medical functions. This study was conducted to detect human diaphragmatic breathing flow using theoretical and experimental approaches. Initially, the lung model was formed using the finite element method and the Navier-Stokes equation by applying the principles of momentum and continuity. Furthermore, fiber Bragg grating (FBG) and single mode fiber (SMF) were experimentally designed with sinusoidal patterned macro-scale bending as a stretch sensor in a breathing belt applied to the diaphragm. The simulation model shows the airflow velocity increases up to 4 m/s when it flows into smaller branches. While the experimental results show that the largest power loss occurs at a buffer diameter of 0.8 cm. The power loss detected in SMF is a maximum of -0.18 dBm during inhalation and a minimum of -0.28 dBm during expiration. However, FBG bending is superior with high sensitivity.
