Abstract

This research aims to determine the students’ perceptions of Guided Inquiry learning on physics and the effect of learning on collaboration abilities and scientific attitudes. This research is survey research. The subjects in this study consisted of 36 students from class X MIPA 1 MAN 1 Siak in the 2022/2023 academic year. The research instrument consisted of 20 statement items, including 8 Guided Inquiry statement items, 7 Guided Inquiry learning effects statement items on collaboration skills, and 5 Guided Inquiry learning effect statement items statement on students' scientific attitudes. Data on students' perceptions of Guided Inquiry learning were analyzed by descriptive analysis. The results of this study indicate that 39 students' collaboration abilities are in a low category and 40 students' scientific attitudes are in a low category. While the application of Guided Inquiry learning with a score of 59 is in the sufficient category. The conclusion of this study shows that the effect of Guided Inquiry learning on students' collaboration abilities is in a low category, the effect of Guided Inquiry learning on students' scientific attitudes is low and the use of Guided Inquiry learning has not been maximized so that it is necessary to use the Guided Inquiry learning model to improve collaboration abilities and scientific attitudes of high school students

Abstract

Abstract : Learning physics in its application is not just gathering knowledge, but must emphasize giving direct experience to foster the ability to think, work and act scientifically and communicate it as an important aspect of life skills. Therefore, to facilitate the learning process of physics must use creative and innovative ways so that learning objectives can be achieved optimally. The results of the 2015 Trends in International Mathematics and Science Study (TIMSS) state that students' understanding of concepts in learning physics is still very low, therefore to improve students' conceptual understanding in the 21st century, an alternative can be done through the application of the PhenoBL learning model so that the learning process learning becomes interesting and fun for students in understanding and relaxed. This study aims to describe and find out the differences in students' understanding of concepts that apply the Phenomenon Based Learning model with conventional learning. The type of research used was a Quasi Experiment with a Posttest Only Design, namely using one experimental class and one control class. The sampling technique used is simple random sampling. The sample in this study were students of SMAN 1 Mandah with class XI IPA 2 as the experimental class and class XI IPA 1 as the control class. The research data was collected by giving a test in the form of a posttest which totaled 14 questions which were analyzed descriptively and to see an increase in students' conceptual understanding using SPSS 23 as an inferential analysis. The results of the research from the descriptive and inferential analysis showed that the students' understanding of the concepts in the experimental class and the control class were different, especially in terms of temperature and heat, the average score of the experimental class was higher than that of the control class. From this study it can be concluded that the PhenoBL model can improve students' understanding of concepts at SMAN 1 Mandah.Keywords: Concept Mastery, PhenoBL model, temperature and heat .

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

This research utilized the Physics at School application to utilize the Learning Cycle 8E model to explain students' conceptual mastery in class X SMA and identify any disparities in conceptual mastery for students in class X SMA. This kind of research uses a quantitative Nonequivalent Post-Test Control Group Design research design and a Quasi-Experimental research method. This research was performed at SMA Negeri 1 Teluk Kuantan. The aims of this research was to implement the Learning Cycle 8E model with assistance from the Physics at School program. In contrast, the second class uses conventional learning techniques as a control class. The data used in this research were concept mastery scores obtained from students who had learned physics using the Learning Cycle 8E model with assistance from the Physics at School program. Based on a descriptive and inferential examination of the data, it was found that the experimental class students' level of concept mastery increased by 73.08 points, while the control class was 69.70. Certainly, Learning Cycle 8E model, which is supported by the Physics at School application, has an impact on how well SMA Negeri 1 Teluk Kuantan children understand certain concepts.

Abstract

The Sekolah Penggerak program is one of the Indonesian Government's efforts to realize the vision of Indonesian education, namely an advanced Indonesia that is sovereign, independent, and possesses the Pancasila personality. As the leading actors in education, teachers play an important role in implementing educational programs. This study was carried out to examine the experiences of teachers involved in the Sekolah Penggerak program regarding the impact of implementing the program. This study is qualitative with an exploratory case study design and a retrospective approach. The participants in this study were 15 mover teachers willing to participate, selected using a purposive sampling technique. To collect data, an open-ended questionnaire, and semi-structured interviews were used. The results of the study reveal that, in general, the Sekolah Penggerak program has a positive impact on teachers, namely helping them change mindsets to be more innovative in utilizing student-focused learning, and on students, namely increasing their motivation and critical skills. The experiences after participating in the Sekolah Penggerak program also direct teachers to be involved in collaborative reflective practice of program implementation to produce teachers who are more professional so that this program runs more effectively in the future.

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.
