Introduction
Natural science is a subject that contains a variety of life materials. Science learning in elementary schools is essential because it can be one of the means to adjust the progress of science and technology. Natural science or science learning in Indonesia has been given to students from elementary, junior, and high school. Learners at the primary school level must understand the basic concepts of science correctly. Students are expected not only to memorize but are required to be able to think critically and creatively, sensitive to the environment, and be able to master modern technology. According to Ref. [1], some schools still need efforts to improve the quality of science learning to produce good outputs.
Improving elementary science learning quality requires learning innovations, including selecting methods, models, or learning media. Learning media is the most critical component that the teacher must prepare. Teachers as facilitators play a role in innovating media development that supports the learning process so that the learning process is not tedious, especially in science subjects [2]. Using appropriate learning media will undoubtedly affect the achievement of learning objectives.
The results of interviews conducted by Ref. [3] with MI YAPPI teachers, MIM Karanganyar and MI Maarif Patalan, stated that there are students who are less interested in participating in science learning because not all teachers use learning media. So that many students ignore the teacher when explaining the material. In addition, problems in the field arise because teachers have not used various learning media. It results in students being easily bored and not understanding the material presented by the teacher. At the elementary school level, science learning materials must be attractively packaged. A literature review is needed to increase the information obtained about science learning media in elementary schools to gain additional knowledge about elementary science learning media. It can be used for human purposes. Journals are essential to be used as a means of scientific interaction to exchange researchers' information.
Through journals, teachers can add information and knowledge about various learning media that can support the teaching and learning process. This bibliometric literature study is essential to understand the extent to which research on elementary science learning media has developed as a reference or reference for subsequent teachers and researchers. Research articles are limited to the last five years (2017-2021) because researchers want to get data that is still relevant and up-to-date.
The bibliometric analysis intends to analyze the extent of the development of n themes regarding elementary science learning media. Besides that, researchers also describe each keyword in this study so that it can see opportunities for future research. A literature study, or what is known as a literature study, is one of the research activities carried out by collecting 3 information and data using various types of materials contained in libraries, such as reference books, relevant research results, articles, notes, and appropriate journals [4].
Natural Science is a subject designed to help students formulate systematic knowledge, ideas, and concepts about the surrounding nature and believe that God created nature on this earth [5]. Elementary science learning aims to make students master the concept of science and its interrelationships and develop scientific attitudes to solve the problems they face so that they are more aware of the greatness and power of His Creator.
The use of learning media in science learning needs to be considered. Media comes from the word medius, which means middle, intermediate, or introductory. The definition of media in Arabic is the intermediary or delivery of messages from the sender to the recipient.
Learning media is a means of transferring information that is made or used under learning theory. It can be used to channel messages and stimulate students' thoughts, feelings and desires to motivate the occurrence of a deliberate, purposeful, and controlled learning process.

Result and Discussion
After searching the data, researchers found 111 journal articles to be processed and analyzed. These journal articles are international journals whose research is carried out in Indonesia and national journals that have been indexed by SINTA one, two, three, four, five, and six. Descriptively, the data from journal articles are presented in Table 1.    [7], learning media [8], learning outcomes [9], and development [10]. Many researchers have used topics with these keywords. Based on the results of this interpretation in figure 1, it forms 25 clusters. Keyword mapping was carried out as an initial stage to find out the general visualization and research trends that are widely researched [11].  On the map, VOSviewer gives finger colours from dark blue to yellow. The Overlay Map will visualize the latest discussion trends with the network having a yellow colour. Figure 27 shows that the articulate storyline [2], media development [2], STEM-based science learning [2], 21st century [12], canva [12], application of learning media [13], wondershare filmora software [13], mobile learning [14], monopoly games [8], mastery of concepts [15], en-alter source [16], animation [17], online [17], discovery learning [18], interest and learning outcomes [19], animated videos [20], and development models [7] are keywords that emerged in 2021. So that it can be interpreted that there is an opportunity and need for further research on the topic.
Most learners at the elementary level prefer fun-packed learning. One of the signs that students are less involved in learning activities is when they are silent when the teacher explains the material. Students are less interested in the learning material because of its complicated and complex nature [35]. If the teacher can choose suitable learning media, it will undoubtedly affect the student's ability to capture the material presented. The results of this study show that multimedia is one of the suitable media used by teachers in explaining science material at the elementary school level. In addition to multimedia, there are other media such as learning videos, comics, pop-up books, powerpoints, and others.

Conclusion
Based on the data analysis and discussion results, the highest development of research journal articles on elementary school science learning media for 2017 to 2021 indexed by SINTA occurred in 2018. From 2017 to 2021, the keywords widely found are science, learning media, learning outcomes, and development. So it shows that the research trend discusses a lot about these keywords. The opportunity to research topic trends in learning media can still be done by selecting keywords that previous researchers rarely used. It included training, abstract science, learning independence, science process skills, cartoons, flashcards, index card matches, puzzles, mastery of concepts, and monopoly games. You can also choose research topics with the latest discussion trends, namely using articulate storyline keywords, media development, STEM-based science learning, 21st century, Canva, application of learning media, wondershare filmora software, mobile learning, monopoly games, mastery of concepts, enalter source, animation, online, discovery learning, interests and learning outcomes, animated videos, and development models.
