Carbon nanotubes (CNTs) have been rigorously studied during the past decade due to their extraordinary physical, chemical, mechanical, electrical and optical properties. The purpose of this research is to conduct bibliometric analysis in carbon nanotubes synthesis by combining mapping analysis using VOSviewer software. Application reference manager used to obtain research data, namely Mendeley. The data obtained is the result of a search based on the keyword " Synthesis Method of Carbon Nanotubes ". From the search results, 247 relevant published articles were found in the range of 2018-2022. The results showed that the number of articles researching carbon nanotubes synthesis has been increasing since 2018 until 2021. However, there have been 8 articles that published in the early of 2022, this number could be increased by the time. Research that is being popularly studied by researchers until today is about review due to the COVID-19 pandemic situation that forced the researchers to decrease experiment activity and physical interations. This research is expected to help and become a reference for researchers in conducting and determining the research themes to be taken.

Heat exchangers are often found in the chemical process industry, but of all types of heat exchangers, the Shell and Tube Heat Exchanger (STHE) is the most commonly used. The design of heat exchangers has also been done a lot because it can reduce production costs. Therefore, this study purpose to design a tube and shell type heat exchanger for applications in producing nano zeolite. The TEMA standard is used as a reference for data collection regarding equipment specifications and dimensions. The parameters are calculated using basic Microsoft Office applications. Shell and Tube type heat exchanger (one pass) with 43 pcs of tubes has been successfully designed. The effectiveness of the heat exchanger reaches 80.02% so it is hoped that this research can be used as a reference in designing a heat exchanger with a better design.

Heat exchanger plays an important role in industry. In industrial applications, the type of heat exchanger that is often found is the shell and tube type heat exchanger. The aim of this paper is to of tube and shell type heat exchanger for nanofibril cellulose production applications. The method used is to design several assumptions and calculate parameters related to determining the performance of the heat exchanger. The parameters are calculated manually using the Microsoft Excel application. In this design, the TEMA standard is used as a reference. The result of this paper is the heat exchanger has 53 pcs of tubes with the effectiveness up to 89.21%. This indicates that the overall performance of the heat exchanger in cellulose nanofibril production applications can be further improved by selecting the right fluid, fluid flow rate, and other physical properties, as well as the number of tubes that will be required

The purpose of this study was to analyse the teaching of clean and healthy living culture in daily life through online learning using digital media. This learning uses Zoom meetings, google forms and the Wordwall site and provides pretest and posttest before and after learning to 22 junior high school students in Dayun District. Learning begins by introducing a clean and healthy living culture and the use of digital media such as Zoom meetings, Google forms and the Wordwall site. Pretest and Posttest are given through Google Forms with 20 questions. The results of the pretest and posttest given, show on average that students can know well the culture of clean and healthy living in daily life by using digital media as much as 81.82 points, but in using digital media as a tool for learning for students less can be said. This is due to various obstacles faced by students including, students rarely interact with teachers via zoom and only give homework through Google Classroom and WhatsApp, there are network problems or signals that occur when online learning takes place and lack of knowledge of digital media used such as laptop or cell phone. In this case, the introduction to sites such as Wordwall is also very minimal, so it requires a lot of interaction in using the site. This research can provide new information about learning the culture of clean and healthy living through online learning using digital media and shows the obstacles in using it

This research aims to find out how elementary school students respond to teaching about the definitions and concepts of the Solar System using digital media. The researcher uses a quantitative method with a Pre-Experimental Design model to support this research because the data collected and the analysis are quantitative. The target of this research is students in elementary school, which is then taken as a sample of 20 students from sixth grade in Bandung Regency, Indonesia for research. The media used during the research were powerpoint and Infographics. The research was carried out offline and one class was divided into two groups, namely Group A and Group B. The results of this study indicate that the use of digital media in science learning material for the Solar System is declared effective, as can be seen from the results of the pre-test and post-test which show improvement, especially in the aspect of students' knowledge in understanding the material of the Solar System. The Pre-Test shows that almost all respondents do not know much about the solar system. However, when given learning materials using digital media such as powerpoint and Infographics, respondents, namely students, understood and understood the material as evidenced by the Post-Test results. Therefore, it can be concluded that in this study, the application of digital media to elementary school students can be implemented properly.

This study aims to analyze the application of interactive power point as a digital learning medium in increasing the understanding of temperature and heat theory in elementary school students. The study was conducted on 37 elementary school students in the city of Bandung using conventional teaching methods and demonstrations. We also use interactive power point media and Google Meet in the learning process. To determine the level of students' understanding of the material, researchers used evaluation techniques in the form of pre-test and post-test, each of which included as many as 20 questions through Google Form. The results showed that students got an average increase of 2.48 in learning outcomes. The increase shows that 68.92% of the material can be understood by students. This is because the learning process using conventional teaching methods, demonstrations, and interactive power point learning media can increase students' attention and focus, so they don't get bored while learning. Therefore, this study provides information that interactive power point media can be used as an interesting learning medium that can increase students' understanding of temperature and heat material.

The Covid-19 pandemic causes learning activities to be carried out online, causing teachers to be able to utilize technology-based learning media. This study aims to determine whether there is a significant difference between the ability to work on kindergarten students' numeracy questions before and after being given learning through YouTube media. The method that will be used is descriptive quantitative to 19 kindergarten students. The results show that the data processing of the Wilcoxon test results is 0.449>α=0.05. From these results, we can conclude that the YouTube learning media has no significant effect on the ability to recognize numbers and do arithmetic problems. This is because (i) the research time is short, (ii) the instructional video is only given once, (iii) some parents do not provide learning videos to students, and (iv) there are still many students who have difficulty writing numbers correctly. But of course, the experience of students learning to use YouTube can still be useful to help students continue their education to the next level.
