Abstract

Measuring the brightness of the night sky and determining the start of Fajr prayer times can be done using SQM. Observations were made at OIF UMSU with coordinates 3o 34' 55.06" N and 98o 43' 17.09" E. The sky brightness was measured using three SQMs mounted facing the zenith, eastern horizon, and western horizon. The night sky brightness values for SQM directed to the zenith, eastern horizon, and western horizon are 18.23 mpsas, 15.82 mpsas, and 15.47 mpsas. The beginning of fajr prayer time produced by SQM is after the beginning of fajr prayer time obtained using the Accurate Times concerning the Sun's altitude 18o below the horizon. The difference obtained by SQM directed to the zenith, eastern horizon, and western horizon is 29.5 minutes, 36.7 minutes, and 39.5 minutes. In other words, the beginning of Fajr prayer time used in Indonesia is earlier than it should be.

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

This study aims to determine the effect of flight activity noise intensity on student learning concentration. This study involved 48 students (male = 24 and female = 24) who were randomly selected in the Islamic elementary school Waioti, Maumere. The intensity of flight activity noise during classroom learning activities is measured using a Sound Level Meter (SLM), and students' concentration levels were measured using a 5-level Likert scale learning concentration questionnaire. The effect of flight noise intensity on student learning concentration was determined using linear regression analysis. The results showed that the noise level due to flight activities in the Waioti Islamic Elementary School was 58.92 dB, exceeding the set threshold value. The intensity level of students' learning concentration disorders reached 71.43%, including frequent disturbance. The level of flight activity noise significantly affects student learning concentration with the regression model: Y = 49.972 + 0.834X with R2 of 0.635.

Abstract

Online learning is learning that is applied by all educational institutions today. The use of appropriate media can support student effectiveness in education, especially in applied physics courses. This study aims to see online learning's effectiveness using quizizz educational media during the covid-19 pandemic in applied physics courses. This research uses a descriptive research method. The population in this study were students of the Almuslim University Physics Education Study Program. The sample selection used a purposive sampling method, namely students who were taking applied physics lectures. The data collection techniques used were tests (quizzes) and questionnaires. This study indicates that quizizz educational game media is one of the most effective online learning media used during the Covid-19 pandemic in applied physics courses.

Abstract

This study aimed to analyze students' conceptual understanding by using a multi-representation assisted discovery learning model in measurement. This research was conducted in Public High School 1 Kendari. This research is a quasi-experimental study using a one-group pre-post test design. The research method consisted of a conceptual comprehension test using a caliper and a screw micrometer in an essay in the form of a multi-representational test on long measurements. The analysis showed an increase in conceptual understanding between the pre-test and post-test with an average pre-test score of 16.24 (SD = 14) and a post-test of 61.4 (SD = 21). These results indicate an increase in students' understanding of concepts after learning with an average N-gain increase of 0.5 (SD = 0.2) in the medium category. It also obtained the most significant increase in students' understanding of the indicators mentioned parts caliper and micrometer with an N-gain average of 0.6 in the medium category.

Abstract

Semiconductor materials can be used as potential barriers to Tunnelling effects. In this study, four semiconductor materials are arranged in various ways to form a quadruple potential structure to analyze the value of the transmission coefficient. The analysis was conducted using the analytical and numerical matrix propagation method using Matlab2018a. The results confirmed that the inverted arrangement produces the same transmission coefficient value for each energy. So that there are 12 kinds of transmission coefficient values generated from 24 arrangements. The semiconductor material composition with the most considerable transmission coefficient value is ADCB and BCDA, which have a value of 0.8087. The variation of the arrangement affects the value of the transmission coefficient so that it can be used as a guideline for selecting the arrangement that produces the most optimum value of the transmission coefficient from various possible arrangements.
