This study aims to determine the outcomes of research conducted by students in the Faculty of Social Sciences between the academic years of 2018 and 2020, as well as the suitability of those results, which includes: the scientific field studied, what topics are saturated and no longer in demand, and the trend of topic distribution growing. At this study, the Deway Decimal Classification (DDC) standard was used to map out the distribution of research fields among students in the Faculty of Social Sciences. In order to develop the roadmap for each study program at the Faculty of Social Sciences, State University of Medan for the upcoming student research, this research combines quantitative and qualitative methods to determine the distribution of thesis research topics. The thesis sample data obtained from the Medan State University Repository was processed using the VosViewer program by means of the data first tabulated with the help of M.S. Excel and the Open Refine Application then analyzed descriptively qualitatively. According to the study's findings, Medan State University's Faculty of Social Sciences will have graduated 1,341 theses between 2018 and 2020 consisting of the History Education Study Program, Geography Education, Anthropology Education and Civics Education. According to data from a mapping of scientific fields based on DDC that depicts the research areas of each study program in the Faculty of Social Sciences, education, research, related historical topics, geography education, national and ethnic groups, and citizenship and related topics are the ones that students are most interested in researching .


Background of Study
The departments of History Education, Geography Education, Anthropology Education, and Civic Education make up the Faculty of Social Sciences of State University of Medan. One of the seven faculties overseen by the State University of Medan is the Faculty of Social Sciences.
The Faculty of Social Sciences's goal is to become a faculty that excels in the advancement of social sciences and education. Teaching social sciences and professional competency-based education is the goal of the faculty of social sciences. Through individual and institutional research endeavors, develop education and the social sciences. Applying education and social science to the larger community through volunteer work and partnerships with diverse organizations promoting initiatives to build a society that is founded on the high ideals of the country's culture and is religious, moral, disciplined, professional, and has a work ethic (Fakultas Ilmu Sosial, 2022).
One of the objectives of the Faculty of Social Sciences (FSS) is to produce graduates with competence in social science education and social science knowledge who are useful for themselves in productive activities and are able to serve the community with attitudes and behaviors that are in line with common life (Fakultas Ilmu Sosial, 2022).
It is vital to perform study on the thesis results to determine how much the vision and mission of Medan State University, particularly in the Faculty of Social Sciences, are supported by the student thesis research findings. Conducting research is a requirement for students to graduate from higher education. There are still numerous fields or topics that have not been examined due to the fact that students' studies are frequently grouped and overlapped. Therefore, it is crucial to map the study findings of these students, including not only the research's titles but also its subjects and objects as well as the connections between these studies.
The research's scope is restricted to the information contained in the final projects or theses produced by students enrolled in the Bachelor's or Strata 1 (S-1) program at the Faculty of Social Sciences, State University of Medan, where the thesis is one of the requirements for graduation. The thesis year is only permitted for the 2018-2020 academic year, or for three years.
The purpose of this study's findings is to establish a research roadmap for undergraduate students so that it can be used as information and input for the administration of the university and Faculty of Social Sciences, State University of Medan, to evaluate the distribution of fields or objects that students in the faculty study. in finishing his capstone project, Medan State University Social Sciences.
Dewi conducted a similar study under the heading "Mapping Literature in Thesis of Library Information Management" (Rachmaningsih, 2022). This study comes to the conclusion that student theses include a wide range of scientific languages, types, and topics. The literature that makes up library and information science is dynamic and interconnected because it will continue to be influenced by trends that are becoming popular research topics, advancements in other scientific fields, students' capacities and preferences for choosing literature, the supervisor's perspective on directing references, background knowledge /education of lecturers and students of the situation and condition at the time the literature was cited, and developments in other fields of study (access, technology, policies, costs, etc.).
"Bibliometric Study and Distribution of Special Collection Topics for the Academic Community at STAIN AL-Fatah Jayapura 2007-2017 (now IAIN Fattahul Muluk Papua)" was the title of Tuwaji's second study. Tuwaji (2019). The investigation comes to the following conclusions: (1) The distribution of written knowledge is not uniform. Islamic religious education, reading and writing the Qur'an, learning methodologies, teaching, and in this instance teachers' teaching are subjects that are frequently written about. The study of curricula, Islamic tolerance, students, education, and guiding systems are still relatively under-written fields of science; (2) The most productive authors in terms of output are Idrus Al Hamid and Umar Faruq with 11 titles, followed by Sofwan Aljauhari with 3 research reports, an anthology of articles with 4 titles, and Idrus Al Hamid and Safiudin. (3) The level of author collaboration is still very low, with multiple authors contributing only 4.07% of the total, compared to individual authors who contribute 95.07%. (4) The use of references with a low level of obsolescence means that some of the literature or books used as references are both recently published books and commonly used books with a low level of obsolescence. The collection of scientific writings-books (0.6) and research papers with the degree of collaboration may be found (0.38). (4) The use of references with a low level of obsolescence means that some of the literature or books used as references are both recently published books and commonly used books with a low level of obsolescence. The most recent references utilized, according to the statistics, are 34% of 0-5 years old, 38% of 6-10 years old, and moreover, reference books with a higher level of obsolescence are used less frequently. According to (Pattah, 2013), curriculum analysis and evaluating the caliber of research findings are two advantages of bibliometric studies. Bibliometrics can be applied in all facets of quantitative and scientific communication methods, storage, diffusion, and retrieval of scientific knowledge, according to Marraro (2008) in (Pattah, 2013). Various forms of scientific literature, such as books, monographs, research reports, theses, dissertations, articles in series and periodicals, and other primary sources are the subjects of study in bibliometrics, according to Glazel (2009) in (Pattah, 2013).
According to (Supardan, 2017), social science is a study of the scientific discipline that focuses on the interactions within society as well as the link between people and their surroundings. In order to improve living standards, it is crucial to comprehend how humans and social sciences interact. Humans have a significant influence on the development of social science. Understanding social phenomena, such as collaboration or conflict, is the goal of social science. The author views and groups many fields that are included in the social sciences using a structural perspective (Dadang (Supardan, 2017).
According to (Gie, 1999), "understanding social sciences" is a catch-all term for all scientific information that applies to general science (Science in General). The world we live in today and the perspective we have of it have both been greatly influenced by science. According to (Soekanto, 1993) the term "social" refers to interpersonal interaction or social activities. Therefore, it may be said that social science is the study of social processes that take place in society. Melvil Dewey created the Dewey Decimal Classification (DDC) (1851 -1931). DDC is a hierarchical system classification diagram that divides all areas of knowledge according to the decimal principle (Zen, 2009). DDC divides human science into ten main classes, ten divisions, and ten sections for a total of ten main classes, one hundred divisions, and one thousand sections (Rahayuningsih, 2007).
The Dewey Decimal Classification (DDC) standard was used to organize the social sciences into categories (300-399) for social sciences and (900-999) for geography and history, along with a variety of other related areas. The following scientific disciplines were looked into: education in history, geography, anthropology, and PKn (Civics Education). The Dewey Decimal Classification (DDC) standard further subdivides each of these disciplines into more focused subjects.

METHODOLOGY
The development and application of mathematical models, theories, and/or hypotheses pertaining to natural phenomena is indeed the goal of quantitative research (Sugiyono, 2014). Descriptive analysis, which is described as an analysis carried out to analyze the features of a data set, was performed on the findings of the observations and interviews (Hidayat, 2012). According to Sugiyono, descriptive analysis is a technique used to describe or give a general overview of the thing being studied using data or samples that have been obtained without analysis or drawing generalizable conclusions (Sugiyono, 2014). The population of the research object for this study is all of the Faculty of Social Sciences' 2018-2020 thesis grads. Purposive sampling with a limit of 1341 theses for the years 2018 to 2020. The purposive sampling approach is a non-random sampling method in which the researcher chooses the sample based on certain factors related to the goals and objectives of the study, specifically that the sample has the data the researcher needs for the success of his or her investigation (Muljono et al., 2009).
The thesis data used in this study came from the Medan State University Library's thesis database. The data for the most recent three (three) years, from 2018 to 2020, are the criteria for the data collection. Based on the year of the thesis, the data is represented by the social sciences faculty's symbol. Additionally, the data is tabulated in accordance with the study program at the Faculty of Social Sciences, Medan State University, which comprises of education in history, geography, anthropology, and civic Education. Following tabulation, the data are organized according to the Dewey Decimal Classification (DDC) standard per scientific field.
With the use of Microsoft Excel and the OpenRefine Application, data from the thesis database sample was processed by tabulating, and the tabulation was then descriptively and qualitatively assessed. Data analysis is the act of carefully gathering data through observations, interviews, field notes, and documentation. This is done by classifying the data into groups, describing them as units, synthesizing them, arranging them into patterns, and deciding which ones are most significant. Explain what will be examined, and draw conclusions that are clear to both the author and the reader (Sugiyono, 2014). Muljono et al. cite Spradley (1980) as saying that the step-by-step technique of analysis was used specifically for qualitative data. In this method, data collection and analysis were completed simultaneously, so that when the observation stage was completed, the interview stage was also completed. When conducting observations and interviews for the following stage, the results of the analysis of the observations and interviews are employed (Muljono et al., 2009). The VosViewer application developed by Nees Jan van Eck and Ludo Waltman is used to exhibit a keyword or co-word map and keyword density (density visualization) that appear in the UNIMED Faculty of Social Sciences 2018-2020 documentaries. The VosViewer application is a computer application tool that can be used to view bibliometric maps (Tupan, 2016). Meanwhile, according to Purwoko, one of the VosViewer applications is used to visualize bibliographies, or data sets containing bibliographic fields and in research, this application is used for bibliometric analysis and looking for topics that still have opportunities to be researched (Purwoko, 2019). This study tracks the keywords used by students when uploading their own theses to the Medan State University Library database in order to create a map of co-words or subjectkey words in student research. The studentgenerated keywords are then chosen and validated to obtain those that have full meaning, eliminating incorrect and incomplete keywords. Then, using VosViewer, the keywords are processed after being translated into Indonesian.

Keyword-Subject Roadmap Visualization
"The map of the field of science is a depiction of the field of science in two or three dimensions," claimed Noyons (2001) in (Rahmaida, 2017). The symbols on the map denote the themes and issues in the scientific field depicted, making it possible to refer to this map as a "landscape of science." Cooccurrence serves as the foundation for the majority of field maps. The tighter the relationship between the two elements and their visual proximity to their respective locations on the map are, the more pairs of elements that appear together.
The procedure of visualizing the processed roadmap data that is available in the keyword-subject table and then being examined with the aid of the VosViewer program is described in this study. With the aid of the VosViewer program, data analysis tasks are completed together with network visualization, overlay visualization, and density visualization of predefined keywords and subjects. Based on the analysis's findings, the VosViewer program may display data on the amount of keyword-subject items that are dispersed in clusters, as shown in the table below. Source: Student Thesis of History Education Study Program Graduates 2018-2020, DDC (Dewey, 2011), andLCSH (Library of Congress, 2000).
The first 12 keywords-subject items (41.38%), second and third 6 keywordssubject items (20.69%), fourth 3 items keyword-subject (10.34%), and fifth 2 items keyword-subject are those included in the clusters, if the distribution of the number of keywords-subjects in table 4 above is sorted from most to least (6.90). When the distribution of the number of keywords-subjects in table 4 above is ordered from most to least among eight clusters (clusters), those that are included in the clusters are: The first nine keywords-plussubject items (21.95%) are followed by seven keywords-plus-subject items (17.07%), six keywords-plus-subject items (14.63%), five keywords (12.20%), three keywords-plussubject items (7.32%), and two keywords (4.88%). The distribution of the number of keywords-subjects in table 4 above, if sorted from most to least, would include the following clusters: first 7 items of keyword-subject (25.93%); second 6 items of keyword-subject (22.22%); third 5 items of keywords (18.52%); fourth 3 items keyword-subject (11.11%); and fifth, sixth, and seventh with each 2 keywords-subject items (7.41%). The following clusters would be found in table 3 above if the distribution of the number of keywords were ranked from most to least across eight groupings: The first six keywords-subject items make up 18.18% of the total; the second and third have five keywords-subject items, which make up 15.15%; the fourth and fifth have four, which make up 12.12%; and the sixth through the eighth have three, which make up 9.09% of the total.

Overlay Visualization
The following graphics provide a visualization of the overlay of keywords and subjects from the theses of graduates from the history education, geography education, anthropology education, and civics education study   The distribution of the trend in the research year for the Geography Education FSS Unimed Graduates 2018-2020 thesis may be interpreted as follows, as shown in Table 8 and

Density Visualization
In the thesis of the Faculty of Social Sciences, State University of Medan graduates in the years 2018-2020, the findings of the analysis from the VosViewer Program have been successfully displayed in the form of visualization of keyword density, as shown in the picture below.  Figures 10-13 above give an overview of the keyword density-subject visualization, where a cluster of keywords-subjects is extremely noticeable between two keywordssubjects, is obviously greater in size than the subject-keyword, and is accompanied by a lighter backdrop color. Because the subject is dense and the background color of the text is lighter than the subject, the visualization really shows that there is a tendency for the volume of research to go toward keywords.

CONCLUSION
From the data above, it can be concluded that based on the Dewey Decimal Classification (DDC) the distribution of the number of fields of knowledge in the thesis of the Faculty of Social Sciences Unimed graduates in 2018-2020 is in Appendix 1. History Education Study Program for research topics is based on the Dewey Decimal Classification (DDC) from position 12 The highest number of the first is in class 907 related to "Education, Research, Related Topics of History" totaling 97 studies (30.41%), while research topics are still little researched at number 12 in class 911 related to "Historical Geography" as many as 6 research (1.88%), and for 38 trends, other research topics may be topics that are already saturated and no longer in demand or indeed those that are still the least researched. If it is still a little researched, it is hoped that it can be material for further research, and as for the other 38 themes, they can be the least researched or ones that have previously been well explored but are no longer in demand. If there is still room for more investigation, it is hoped that it will serve as a starting point.
Appendix 2. Geography Education Study Program with the most research topics, according to the Dewey Decimal Classification (DDC), from the top 11 positions, with the most number of first being in class 910.71 related to "Geography of and Travel;" amounted to 82 studies (22.16%), while research topics were still sparsely researched at number 11 in class 577.6 related to "Aquatic Ecology," as many as 6 studies (1.62%), and for 39 trends other research topics If there is still room for more investigation, it is hoped that it will serve as a starting point.
Appendix 3. Anthropology Education Study Program with the most research topics based on the Dewey Decimal Classification (DDC) from the top 11 positions, with the most first being in class 305.8 related to "Existence" totaling 17 studies (5.74%), while the least researched in class 306,432 related to "Social Sciences; School and Society" with as few as 6 studies (2.03%). For the 39 trends, other research topics could be topics that are already saturated and no longer relevant. If there is still room for more investigation, it is hoped that it will serve as a starting point.
Appendix 4. Civics Education Study Program with the most research topics based on the Dewey Decimal Classification (DDC) from the top 15 positions with the most first being in class 323,607 1 related to the topic "Citizenship Education" totaled 59 studies (44.36%), while research topics are still sparsely researched at number 15 in class 370,115 related to "Education for Social Responsibility" with as few as 5 studies (3.76%), and for 35 other research topic If there is still room for more investigation, it is hoped that it will serve as a starting point.
