Abstract

Physical systems in partial differential equations can be interpreted in a visual form using a wave simulation. In particular, the interpretation of the differential equations used is in the nonlinear hyperbolic model, but in its completion, there are some limitations to the stability requirements found. The aim of this study is to investigate the analytical and numerical analysis of a wave equation with a similar unit and fractal intervals using the Fourier coefficient. The method in this research is to use the analytical solution approach, the spectral method, and the finite difference method. The hyperbolic wave equation's analytical solution approach, illustrated in the Fourier analysis, uses a pulse triangle. The spectral method minimizes errors when there is the addition of the same sample grid points or the periodic domain's expansion with a trigonometric basis. Meanwhile, different ways offer a more efficient solution. Based on the research results, the information obtained is that the Fourier analysis illustrates the pulse triangle use to solve the solution. These results are also suitable for adding sample points to the same spectra. Fourier analysis requires a relatively long time to solve one pulse triangle graph to need another solution, namely the finite difference method. However, its use is still limited in terms of stability when faced with more complex problems.

Abstract

Not all physics concepts must be understood and mastered by deriving formulas through differential or integral techniques. Mechanics, for example, can be understood with simple logic without formulas, variables, and numbers. The fun method, or known as the GASING method, is a science learning method that has been offered by Yohanes Surya since 1996. This method offers fun learning activities for students. This research is a literature review of several books and research articles related to learning physics science using top methods. It turns out that with the spinning method, the concepts of velocity and acceleration in straight motion material can be understood easily and can solve some physics problems about straight motion without complicated physics formulas. All these physics problems are solved by simple logic and expressed in words.

Abstract

The problems faced today by Indonesian teachers are the difficulty of implementing e-learning in the learning process, especially physics learning. During this time the teacher considers using e-learning in the classroom will not be effective. This study aims to explain how the implementation of physics learning by using Moodle-based e-learning in the learning process. In this study, it divided into two aspecs, namely learning outcomes and interest in learning with physics learning material in rectilinear motion. This study uses an experimental class design with a sample size  X class of 10 students of Public High School 1 Piyungan group chosen randomly. This study used the design of one group pretest and posttest using the T-Test while the significance value using N-gain analysis scores and learning interests obtained from the questionnaire. The results of the analysis show an increase in learning outcomes with very high N-gain significance values. Then the percentage of student learning interest reaches 66% which is in the excellent category. So it can be concluded that the application of moodle-based learning can increase learning interest and learning outcomes and 73% of students agree if knowledge based on Moodle applied in the learning process. Keywords: e-learning, Moodle, learning management system, learning outcomes, interest in learning

Abstract

Vocational High School is a formal institution that creates more independent, creative, innovative, skilled, and responsible students in solving a problem. Graduates from vocational education are expected to be more competent in solving problems in the world of work. Students are also required to be more active in solving a problem. The research objective was to determine student activity and analyze mathematical problem-solving abilities in implementing mathematics learning using the Problem Based Learning model. The method used is to use a qualitative design. In this method, student activity is measure using the observation sheet, and the problem-solving ability test is carried out by following the steps of Polya's theory. The results showed that the overall student activity reached the excellent category. The general average problem-solving ability obtained an ideal classification, with the movement and moderate mathematical problem-solving ability of students achieving a reasonable variety and positively impacting all vocational students.

Abstract

The 2013 curriculum is oriented to the development of the 21st century which is faced with various challenges in the world of education. Things that cause problems in implementing the 2013 curriculum are teacher competencies that are still lacking, online learning facilities are not evenly distributed, and the division of learning hours using a shift system causes the quality of students and education itself to be lacking. This study aims to provide solutions to problems faced in schools, namely by developing HOTS integrated worksheets to improve students' critical thinking skills. This type of research is development (R&D) which refers to the 4-D model, namely define, design, develop, disseminate. The feasibility of the HOTS integrated LKPD media was obtained from the results of expert validation, LKPD media trials in the form of practicality analysis and effectiveness analysis. The improvement of students' critical thinking skills is obtained from the standard value of the N-gain test of students' critical thinking abilities. The results of the study indicate that the HOTS integrated LKPD has been produced which is suitable to be used to improve students' critical thinking skills with a standard N-gain value of 0.71 in the high category.

Abstract

Indonesia is an area where three large tectonic plates meet, namely the Indo-Australian, Eurasian and Pacific plates, so that Indonesia is included in the earthquake-prone category, with 11,660 earthquake vibrations identified in the Meteorology, Climatology and Geophysics Agency (BMKG) database in 2019 The purpose of this study is to develop a classification of the distribution of earthquakes in Indonesia in 2019 based on the values of magnitude, depth, and position. This research was conducted by using the clustering method based on the K-means algorithm and the DBSCAN algorithm as a comparison. The results of the clustering show that the earthquake data analysis using the K-Means algorithm is superior with a silhouette index value of 0.837, while the DBSCAN algorithm has a silhouette index value of 0.730.

Abstract

One of the impacts of the Covid-19 pandemic in the world of education is a change in the learning process from face-to-face learning to online learning. To compensate for these changes, it is necessary to integrate technology in learning. The goal of this study is to design thematic learning at the elementary school level by integrating the Internet of Things (IoT) related to climate change parameters. The method in this study uses research and development of IoT-based measuring instruments using the Lolin V3 MCU node, with sensors for temperature, air pressure, humidity, altitude, and light intensity. The research respondents were 20 students. Data collection was carried out using a questionnaire containing four aspects, namely, usability, ease of use, aspects of learning ease, and satisfaction. The results showed that the reliability value 0.6 and the level of student acceptance of the product was 3.4 with effective criteria. Based on the findings, this instructional design has potential opportunities to increase student engagement even though it is limited in networking. So it can be concluded that IoT-based learning media can be applied as a thematic learning model at the elementary school level during the Covid-19 pandemic.
