The frequency used as a sound source is 495 Hz. Tests were carried out with variations in panel thickness, they are 1 cm, 2 cm, 3 cm, 4 cm, and 5 cm and three variations composite material, they are first layer, second layer and third layer of surgical mask. The panel test results show that the thicker acoustic panels are more effective in reducing noise based on the regression analysis that show the thicker panel from three variations composite material is 0.98, 0.99 and 0.96, respectively all of which are included in the very strong category. In addition, ANOVA analysis show that the thicker panels from all variation composite material respectively was 0.002, 0.001 and 0.009, they are showed the significant effect between the thickness of the panel and the effectiveness of the panel in reducing noise. Furthermore, based on the regression analysis from acoustic panels composite made of surgical masks from first layer, second layer and third layer were 8.24, 8.39 and 5.81, respectively the panel acoustic from second layer surgical masks are more effective to reduce the noise than other layer. Overall, it can be concluded that acoustic panels made of surgical masks are effective in reducing noise, as well as a solution to increasing surgical mask waste during the Covid-19 pandemic.","PeriodicalId":31790,"journal":{"name":"Physics Communication","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87598395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 21st century requires students to be able to integrate technology in learning activities. Android-based learning media is an alternative learning media that is integrated with technology. Science, Technology, Engineering, and Mathematics (STEM) is an integrative approach that can improve critical thinking skills. This study aims to analyze the effectiveness of Android-based learning media with the STEM approach to improve students' critical thinking skills. The study used Research and Development (RD) method, namely introduction, media validation, and media testing. The subject of this research is class X vocational school majoring in motorcycle engineering and business. Data collection techniques used research instruments with quantitative data analysis. The data collection instrument was given through a written test in the form of essay questions that included aspects of critical thinking skills. The results of this study indicate that the results of the n-gain mean the pretest and posttest values was 0.77 with high criteria.

If the level of lighting is below the specified standard, it can cause eye damage. Meanwhile, if the level of lighting is above the standard, the classroom will be too bright. The purpose of this study was to determine the level of lighting in the Regular and Full Day classroom of MTs. Miftahul Huda Tayu. The tools and materials used in this experiment are lux meter, roller meter and thermohygro. The experiment was carried out in the Regular class school building and the Full Day classroom building with a sample of three rooms per building with each room representing each floor. The experiment was carried out during the day for three consecutive days. There are two types of the intensity measured in this experiment, namely natural intensity (lights off) and natural artificial intensity (lights on). In each room, 9 points were taken. The floor area and window area were measured using a roller meter. From the experiments that have been carried out, it can be concluded that the lighting in the Regular class (17-73 lux) and Full Day class (97-181 lux) buildings do not meet Indonesian National standards (Standar Nasional Indonesia, SNI).","PeriodicalId":31790,"journal":{"name":"Physics Communication","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82121556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, researches about problem-solving strategies or techniques based on students’ personality have not been widely practiced. This strategy is important to be studied based on thoughts, characters and actions of students. Therefore, the aims of the research are to connect students problem solving of physics based on their personality and identify students problem solving pattern based on their personality according to The Four Temperament Theory of Keirsey (1998). The method used in this research is descriptive qualitative research with the type of Investigation of Lived Experience that explores inner experiences (Gall et al, 2003). Subjects in this study are 12th grade students of science class program of MAN 1 Banyumas which is determined by stratified sampling approach. They were divided into homogeneous groups. The grouping is based on Keirsey's four personality types: Idealist, Artisan, Guardian and Rational. Each personality type, selected nine students as research subjects are determined using purposive sampling technique. The results showed that the strategy of physics problem solving of Idealist type was conceptual problem solving, Artisan type used intuitive-analogic for solving the problem, Guardian type used intuitive for solving the problem, and Rational type used analogic strategy for solving the problem.","PeriodicalId":31790,"journal":{"name":"Physics Communication","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75157042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Students build the concept through experience gained from the environment, so that they unconsciously have the concept in accordance with the understood. Students still have difficulty distinguishing work and energy definitions in physics and in everyday life. The concept of work and energy can be understood by students if students have good analogy skills. The Brain Based Learning (BBL) model through analogy facilitates learning to improve students' thinking ability analogy. The buying and selling analogy is used to relate concepts that students have understood (source problems) to the concept of work and energy as learning goals (target problems). Quasi-experimental learning is applied to determine the analogy of students. Data were analyzed from the achievement of analogy ability test results before and after learning. The success rate of mastering students' analogy abilities is analyzed from the stages of analogy in solving problems. Achievement of pretest and posttest scores of students 'analogy abilities shows that the BBL model through buying and selling analogy can improve students' analogy skills. The average achievement of students' analogy skills at the stage of generating the analogy includes good criteria, evaluating the analogy relations stage including good criteria, understanding the analogy case stage including good criteria, and at the transfering findings, including not good criteria.
