Trend Information System Research Topics in the SINTA Journal for the Period 2015-2019

—Information systems discipline has developed rapidly over time. Based on 533 information systems study programs in Indonesia, it is possible to have a variety of information systems research topics. However, there is no research on information system topic trends in Indonesia. So this study aims to determine the trend of Information Systems research in Indonesia, which was published in 2015 to 2019 based on the publication of the SINTA journal. The method used is qualitative non-interactive because it analyzes published documents resulting from data collected from the Google Scholar database using Publish or Perish tools. The research flow adopts the recommended PRISMA in improving the quality of the systematic review and better understanding of the readers. Determination of research topics based on abstract content, keywords, and referring to the IS ACM Curriculum and previous research. Research results can be used as academic references to gain new insights into the field of Information Systems. The results of the study obtained 1065 data which were processed based on the publications of the journal SINTA2, SINTA3, and SINTA4 shows that the topic "Application Development" is a trending topic from year to year with a percentage of 31%, the second trending topic is "Decision Support Systems" with a percentage of 11% and trend of the third topic “System Analysis and Design” with a percentage of 10%. The new issues that arose were "Internet of Things", "Machine Learning" and "Artificial Intelligence". Information systems research in Indonesia varies widely, although some studies have a low percentage.


INTRODUCTION
Information systems discipline is a pluralistic field that is built based on other knowledge which is considered more established [1]. The information systems discipline focuses on the disciplines of engineering, computer science, management science, mathematics, and decision-making theory. The current information system discipline has become a reference for other fields because it has wide coverage in various fields such as manufacturing, services, agriculture, health, education, security, and government [2]. The diversity of perspectives means that information systems are a field that is valued as either a scientific discipline or a research field. The relevance of the development of information systems research appears more clearly in the information systems conference, namely the European American International Conference. The recent evolutionary examination of information systems research focuses on a broader business perspective topic and includes contributions outside the context of business operations [3].
Research on information system topic trends abroad has been widely conducted, such as Jeyaraj and Zadeh. who analyzed the evolution of information systems research using modeling techniques. Based on information systems research publication data taken from the Web of Science database for the years 2003-2017. The results of this study found that the topics "IS Implementation", "IT Adoption, and" IS Development "were the top topics in all journals and all year. And new issues that have emerged are "blockchain"s", "internet of things (IoT)", and "machine learning" [4].
Meanwhile, in Indonesia, Bahruni and Fathurrahmad analyzed trends in research topics on the Web of Science and SINTA for determining student final assignments. The method used was Text Mining by indexing words. The results of these studies indicate that the words "Learning", "Network", "Analysis" and "System" are the top keywords [5]. However, the data used in this study are not entirely journals from Indonesia or mixed with publications from abroad. However, the trend of information systems research topics in Indonesia is still unknown. Research by Nur Rohmaniar was analyzing trends in the use of IT frameworks in Indonesia in 2014-2018. The method used was descriptive quantitative. Based on published data from the Google Scholar database, results showed that the framework often used COBIT with a total of 523 articles [6]. However, the weakness of this research is the method used was unstandardized. This research was conducted to improve previous research from published data, focusing more on research on information systems in Indonesia indexed by SINTA 2, 3, and 4. Meanwhile, the method used is to adopt PRISMA (Preferred Reporting Items for Systematic Review).
The purpose of this study is to determine the trend of information systems research topics in Indonesia for the 2015-2019 period. The data used are Google Scholar publications. Google Scholar is a search engine for finding publication sources and citation data for free. From a comparison of several search engines such as Google Scholar, Microsoft Academic, Scopus, and Web of Science, Google Scholar remains the most comprehensive publication source today [7]. including scientific journals from various publishers [8].
Retrieval of data using Publish or Perish tools with the keyword Publisher, where Publisher is an Information System Journal which has been indexed by SINTA 2, 3, and 4. The data obtained was valid. Publish or Perish was a tool Developed by Anne Will Harzing. This tool can retrieve and analyze academic citations from various sources such as Google Scholar, Microsoft Academic, Scopus, Web of Science, and Crossref. Data retrieval, data from Publish or Perish tools can be saved to various output formats for further analysis [9].
The research flow used in this study adopted the PRISMA (Preferred Reporting Items for Systematic Review) Flow Diagram. PRISMA is the result of the development of the QUOROM method [10]. PRISMA has 4 stages, namely Identification, Screening, Eligibility and Included. The PRISMA item is a recommended reporting method in improving the quality of systematic reviews and a better understanding of readers [11]. The flow of this study was adopted from PRISMA, which was modified according to research needs.

II. RELATED WORK
Overseas researchers have made many efforts in research to determine the evolution of the development of Information Systems. Like research conducted by Prashant Palvia and others reviewing information systems research trends for the period 2004-2013, This research is an update from previous research. Besides, this study also looks at the methods, models, and paradigms that are often used in Information Systems research. Based on 2487 articles taken from the most popular Information Systems journal using modeling techniques. The results of this study indicate that the topics "E-Commerce", "IS usage/adoption" and "IS research" are trends in Information Systems research for the period 2003-2017. The method that is often used for surveys, multi-tier influence diagram is most often used in describing the research model, and the positive approach is most often used in words [12].
Noor Al-Qaysi and others researched the theory/model of education and Information Systems used to check the acceptance and adoption of social media using a Systematic Review with a research flow adopting PRISMA. Based on 122 articles published in 2009-2018, the results show that the Uses and Gratifications Theory (U&G) is a theory that is widely used in social media. Besides, the TAM and UTAUT methods are information system models that are widely used for social media acceptance and adoption [13].
Elham Mazaheri and others investigated the topics and methodologies used in information systems as a whole in the 2007-2018 period. Articles taken from the 8 most popular information systems journals. This research was conducted by analyzing the literature, topics, and methodology in general. The results of the research are the topics of E-Commerce/E-Business, information systems research, and IS use/adoption being the top topics. While the method that is often used is a survey [14].
Research in Korea, namely Chang-Sik Kim and others, examines the trend of information systems research topics using topic modeling. Based on 1,245 articles published by the APJIS (Asia Pacific Journal of Information Systems), Information Systems Review, and The Journal of Information Systems, 2002-2016. The results of this study indicate that the common trend topics are "systems implementation", "communication innovation", and "customer loyalty". And the most popular topics are "system implementation" and "website" [15].
Álvaro Rocha and others present and discuss the latest innovations, results, experiences, and challenge about information systems. Meanwhile, the latest research is "intelligent information systems", "computing intelligence" methods in Information Systems, and new trends in "Business Process Management" [16].
Jiao Wang and others summarize the results related to Interorganizational Information Systems in the Journal on the Web of Science and the Chinese knowledge network. The analysis uses Knowledge Visualization tools and creates a visual analysis. The results of this study are four trends in the field of information systems research which include trust factors, Inter-Organizational Information Systems in "cloud computing", "configuration analysis methods", and "Social Perspectives" [17].

III. METHODS
This research is non-interactive qualitative research. It analyzed the document results of journal publication data retrieval using Publish software or Perish. The results of data collection were processed manually using Microsoft Excel software for grouping data based on keywords. To find out statistics and help present data in graphs and diagrams using Microsoft Excel software. The descriptive analysis explained the results of graphs and diagrams in easy-to-understand sentences and to find out the trends in information systems research in Indonesia in 2015-2019. PRISMA Flowchart is a research flow that was adopted and modified according to the needs of this research. The following is a research flow chart. The following is an explanation of the chronology research from Fig. 1:

A. Study of Literature
The literature study stage is the stage of finding references from various relevant readings such as scientific papers, journals, theses, and books related to research.

B. PRISMA Flow
The PRISMA Flow chart is an analysis used in the systematic review. The PRISMA flow chart used in the study was the result of modification according to the research needs. The following are 4 stages in PRISMA Flowchart, namely:

1) Identification
Identification is the initial stage of the PRISMA Flow chart. Identification is an early session of the PRISMA Flowchart. Retrieval or collection of research publication data on the Google Scholar database based on Publisher keywords. Data collection using Publish or Perish tools. The publisher is the name of the information system journal indexed in S2-S4. The following Table I is the name of the indexed journal SINTA 2, SINTA 3, and SINTA 4. Following Table 1 is the Information System Journal data indexed by SINTA 2, SINTA 3, and SINTA 4.

2) Screening
Screening is the stage of filtering publication data. Filter publication data by Title, Years, and Publisher. The title filter is carried out on data where the theme or research topic cannot be identified and duplicated so that there is no duplicate data. Publisher filter, namely the deletion of data that is not known to the publisher or the publisher's name does not match the journal in question. Meanwhile, publications other than 2015-2019 will be removed in Filter Years. The purpose of the Publisher filter is to ensure that the articles are publications of the journal in question and get accurate data. Meanwhile, publications other than 2015-2019 will be removed in Filter Years.

3) Eligibility
At this stage is the determination of the feasibility of the journal/article, where the publisher of the article/journal must be an information system journal indexed in the SINTA2, SINTA3, and SINTA4 categories. This can be known from the Publisher. The results of the Screening session can be processed directly to the Include stage.

4) Included
The last stage is the data processing process which is as follows:  Grouping data based on the category of SINTA  Grouping data by year  Determining the research topic by looking at the abstract content and research keywords. As well as using the IS ACM Curricula reference and the results of topic mapping in previous studies.  Adding and calculating percentages on each resulting topic  Presents the percentage results in graphical form using the following percentage formula:

5) Analysis Trend
This stage is carried out with the help of Microsoft Excel software to perform calculations and present data in the form of tables, charts, and graphs, as well as statistics for each topic. At this stage, a descriptive analysis was also carried out on the processed data to find out the trends of each information system research topic in 2015-2019.

A. Identification
At the data collection stage, 1731 articles were obtained, where this data will be used in research. The following details the number of articles for each journal as shown in Table II.

B. Screening
The first screening is carried out on the Publisher, to ensure that the article is a publication of the journal in question. This is so that the data obtained is accurate. The following Table III is the journal data along with the URL. Title Screening, where the title of the article that cannot be identified as the theme or research topic will be deleted. As well as duplicate data to avoid double data. Meanwhile, publications outside of 2015-2019 and data for which the year of publication is not known will be deleted in Filter Years. The results of the screening are shown in Table IV below.  Register  70  17  5  --22  48  JSINBIS  130  30  81  --111  19  Jurnal Sistem  168  3  108  --111  57   Informasi  JURTEKSI  72  -5  --5  67  INTENSIF  57  1  10  1  -12  45  SISTEMASI  194  2  21  1  1  25  169  JATISI  115  -25  --25  90  TEKNOSI  125  3  1  -1  5  120  Manajerial  186  4  163  13  -180  6  Sisfokom  174  1  50  -4  55  119  JuTISI  410  243  6  6  5  260  150  JUSIM  38  -----38  JsiI  88  3  11  -1  15  73  Ultima  Infosys  90  -26  --26  64 Total 1065 Journal Register with an initial number of 70 articles, a Publisher filter of 17 articles, a Year 5 and 0 filters for the Title filter, the number of deleted articles is 22, so the final data count is 48 articles. While the JSINBIS Journal (Journal of Business Information Systems) with an initial number of 130 articles, 30 articles deleted in the Publisher filter, filter years 81, the number of articles deleted was 111, so the final number was 19 articles. The final data obtained from the screening results are 1065 articles which will be processed at a later stage.

C. Eligibility
The stage in determining the eligibility of the article, Publishers is journals indexed by SINTA 2, SINTA 3, and SINTA 4. Because the data in the study are articles published by information systems journals indexed by SINTA 2, SINTA3, and SINTA 4, the data from the Eligibility stage are as shown in Table V.

1) Research Topic Determination Process
In the process of data processing, identification and determination of article topics are carried out. Manual data processing is by reading the entire title, keywords, and abstract of each article, while in determining the research topic itself refers to the SI ACM Curricula, where this Curricula is a development of the 2002 curriculum and is the result of the collaboration between ACM and AIS [18]. The topic also uses references from previous studies [4], [12], [19]. Determination of research topics is carried out thoroughly and carefully. The results of the research have been reviewed by lecturers with peer knowledge. The following Table VI is a list of the research topics found.   Table 6 is a breakdown of data and percentages and the top 15 topics. In the SINTA 2 category, there are 124 articles and the top topic is "Human-Computer Interaction" with a percentage of 13%, "Application Development" 11%, "Decision Support System" 9%, and "Digital Images Processing" 8%. In the SINTA 3 category with 491 articles, it shows that the topics that are often studied are "Application Development" 29%, "Decision Support System" 14%, "Data and Information Management" and "Expert System" 7%. And the SINTA 4 category has 450 articles, where the trend of research topics that are widely studied are "Application Development" with a percentage of 39%, "System Analysis and Design" 11%, and "Decision Support System" 9%.

2) Trending Research Topics by Years
The results of the percentage of research topics studied by all journals based on 2015-2019 publications as shown in Figure 4. Figure 4 shows the top 20 trending topics by year. "Application Development" is a trending topic that is often studied, this topic is also a trend from year to year.

3) Trends in Research Topics All Journals All Years
There are 38 research topics from all journals and all year. The following Table VII lists the top 20 topics.  Table 7 shows that the top percentage for the topic of "Application Development" is 31%, In the digital era, it is estimated that this topic will continue to increase in the years to come. The top 2 topics were "Decision Support Systems" which reached 11%, while the topics with the top 3 positions were "System Analysis and Design" with a percentage of 10%. 2 topics with a percentage of 6% namely "Human-Computer Interaction" and "Data and Information Development". While the other 15 topics have a low percentage below 5%. The percentage results are illustrated in graphical form as shown in Figure 5 below.    Table 8 is the result of the comparison which shows that "Application Development" is a topic that is still consistently studied in Indonesia for the last 5 years. These results are in line with previous research conducted by Anand Jeyaraj [4] and Prashant Palvia [12], it is related to information system artifacts and is expected to continue to be a research center in the field of Information Systems.
The research topic "Decision Support Systems" is still widely studied even though the percentage at the end of the year decreases. In this study the topic "Decision Support Systems" was included in the top two, this result is in line with previous research conducted by Trihanto [20], wherein his research on the topic "Decision Support Systems" became the top trend. The topic of "System Analysis and Design" is how to analyze business processes by involving technology and information systems to support business needs, is that it is very important to analyze and design so that technology or information systems can be used by business needs [18]. In Indonesia, the topic of System Analysis and Design is still widely studied and ranked in the top three in the last five years, although in 2019 it decreased.
The topic "Human-Computer Interaction" is a topic related to the examination of human performance, methods, technology components, and techniques used in designing and evaluating an information system [18]. The topic of "Human-Computer Interaction" covers the keywords of "IS acceptance", "IS success and IS evaluation", "usability testing", "quality system", etc., this topic persisted with the stable presentation during 2015-2019. The topic "Data and Information Management" covers database administration tasks, key data quality, and security concepts. In the data era, this topic is still in demand in Indonesia with a high presentation in 2019, corporate data privacy requires strict security to remain protected.
While other Information Systems research topics have a percentage below 5%, as shown in Figure 6 below. New issues that arise following previous research are "Machine Learning", the "Internet of Things", and "Artificial Intelligence" [4].
The limitation of this study is the document analysis method which is done manually one by one, this requires accuracy and a long time to get accurate results. So that further research can use a better method and use the Nvivo Plus tools to analyze qualitative data to make it faster and more accurate. While the limitations in other studies are the data used, namely only the published journals of SINTA 2, SINTA 3, and SINTA 4. Further research can use a lot of data with broad coverage, so the results will be more varied.

VI. CONCLUSIONS
In this study, we analyzed trends in Information Systems research topics based on publication data in Information Systems journals indexed by SINTA 1, SINTA 2, and SINTA 3 from 2015-2019. This research is a new research theme in the field of Information Systems in Indonesia. Based on 1065 articles that were processed, 38 Information Systems research topics. This shows the development of the discipline of Information Systems in Indonesia. The research topic that is often researched is "Application Development" with the highest percentage, followed by "Decision Support System" and "System Analysis and Design". Meanwhile, some topics have a total of 1 article which means they are rarely researched, such as "Business Intelligence", Search Engine Optimization "and" Machine Learning ". This can inform us of what has been done and what has not been done for future research. By adopting the PRISMA flow the results obtained are more systematic and accurate.
