Top Indonesia's Journal Efficiency Analysis: Bibliometrics (Scientific Strength) and Data Envelopment Analysis (DEA)

Research in every academic institution is measurable output because the quality of a university can be seen in how much research is produced. Due to the current situation, universities engage in fierce competition to generate extensive research that needs publication in journals. The institution itself mandates lecturers or researchers to contribute to research endeavors to enhance the university's ranking. Furthermore, government systems necessitate lecturers or researchers to produce scientific publications or research to advance their career paths. The positive side of the implemented system makes lecturers or researchers at universities work hard to produce research, not just teaching. Lecturers must also continually learn about the latest scientific developments to enrich their references related to their research. In addition to learning new knowledge related to their field, lecturers must also speak foreign languages and quickly adapt to information technology because many research references are written in foreign languages, especially English. Even some well-known universities require their lecturers to produce scientific publications or research published in international journals, so they must be written in a foreign language. A university's quality is evaluated not solely based on the quantity of research it generates, but also by the impact that research has made. Eugene Garfield pioneered the measurement of the impact of this study, such as Impact Factor or Journal Impact Factor, SNIP (Source Normalized Impact per Paper), Eigenfactor Score (EF), H-index, Cited Half-Life, Immediacy Index, and Article Influence Score. The impact measurement is adapted by the Schimago Journal Ranking (SJR), such as using the Impact Factor or Journal Impact Factor, H-index to see the quality of journals indexed by Scopus, such as Journals in Q1, Q2, Q3, and Q4. In addition to SJR, Journal Citation Report (JCR) such as the use of Impact Factor or Journal Impact Factor, Eigenfactor Score (EF), Cited Half-Life, Immediacy Index, and Article Influence Score to see the quality of journals indexed by Web of Science (WoS). In Indonesia, measuring the impact of Indonesian research is known as the Science and Technology Index (SINTA) under the auspices of BRIN Research and Technology. This platform is to see quality Indonesian journals such as the SINTA 1 Journal, SINTA 2, SINTA 3, SINTA 4, SINTA 5, and SINTA 6. Thus, many lecturers and researchers are trying hard or even competing to be able to publish their papers in reputable or quality international journals. Even at the level of lecturers or researchers, they are required to publish in national or international journals with minimum standards, such as at least in SINTA 2 (for certain positions) and reputable international journals indexed by Scopus and Web of Science (for certain positions). This phenomenon is prevalent in both Indonesia and globally due to the shaping and demanding nature of the existing system. It is not surprising that many lecturers or researchers exert considerable effort to secure publications in national or international journals, sometimes being willing to pay substantial fees for publication in reputable journals. However, even when published in a prestigious journal, there is no guarantee of a significant impact, such as a high number of citations or direct benefits derived from the research results. When undertaking research, it is crucial to take into account a range of variables. The focus should extend beyond merely conducting high-quality research to gain citations. Other factors need to be considered in conducting research, namely financing, infrastructure (facilities), and the number of researchers. This is because universities producing research require research costs and even costs for publication in international journals. The expenses involved in the process are substantial. Nevertheless, if the research gets published in an international journal, it is not ideal if the number of citations is minimal, particularly when assessing its practical utility. This is particularly true in the realm of social sciences, where the direct benefits may not be immediately evident. Therefore, it is necessary to measure efficiency related to the number of articles published in a journal with the impact obtained from its publication. Efficiency measurement is a vital thing that must be done to evaluate whether it is effective or not related to the research produced in terms of how many variables are spent to produce research with the impact obtained. Data Envelopment Analysis (DEA) is a method developed to evaluate performance effectiveness. Efficiency measurement is a vital thing that must be done to evaluate whether it is effective or not related to the research produced in terms of how many variables are spent to produce research with the impact obtained. It is a method developed to evaluate performance effectiveness (Gökşen et al., 2015). The DEA method is usually used to measure university performance, as in the research entitled "Performance of Indonesia's World-Class University Efficiency with Bibliometrics (Scientific Strength) Approach and Data Envelopment Analysis" (Ibrahim & Fadhli, 2021), but in this study, applied to the Journal. DEA is a simple but powerful method to measure efficiency and how much input is produced with the resulting output. Based on these problems, the purpose of the study is to see the value of journal efficiency, where the maximum efficient value can be used as a reference for publication references so that the publication can get more citations.Bibliometrics Bibliometrics is one approach to measuring productivity. Besides that, it can also be used for research assessment or evaluating information. According to Daraio et al., research assessment is more and more becoming a 'big data' activity, involving multiple comprehensive citation indexes, electronic full-text databases, large publication repositories, usage data from publishers' sites, and altmetric, webometric, and other new data sources (Daraio et al., 2016). Bibliometric tools began to be used for evaluating the productivity and scientific impact of research activities in the 1980s, especially in the public sector and universities in the 1990s (Gușu & Butnariu, 2021). Bibliometrics in addition to measuring or evaluating in the field of the public sector and universities, bibliometrics can also be used to measure scientific journals, so it can be said that bibliometrics is an approach or method that can be used to assess or evaluate research performance of a university or Journal. The assessment or evaluation of the performance of this research has a very crucial impact on the institution in its future policy making strategies. Economic indicators in conducting research are closely related to the research impact, such as citation impacts; scholarly impact. Economic law recognizes the term profit, so how much money we spend to produce something, the product must also have a significant impact (profit). The evaluation functions provided by the ESI (Essential Science Indicators) agency of ISI (Institute for Scientific Information) are for those who are mainly engaged in scientific and technological or economic policy in government departments (Qiu et al., 2017). Economic indicators (bibliometrics) are not only used as variables in measuring university efficiency but can also be used to evaluate a journal. Evaluating journals from both usage and economic benefits provides a comprehensive measure for periodical ordering and funding (Qiu et al., 2017). Journal publication costs can be used as a variable in measuring efficiency or evaluating journals, according to Qiu et al., (2017) statement that the price component can be used to evaluate journals(Qiu et al., 2017; Rousseau et al., 2018). Economic indicators are a crucial component in producing research because quality articles should have a good impact, such as the number of productive citations disseminated on social media so that they can be used directly by the broader community for their work. Data Envelopment Analysis DEA is a simple approach that can be used to measure the efficiency of an object (fields: commercial/economic, educational, social, etc.; institutions: companies, universities, institutes, activities). Following the statement by Petridis et al., (2013) that DEA can be used to measure efficiency in DMUs (Decision-Making Units) such as institutions, departments, journals, etc. (Petridis et al., 2013). This DEA approach can be made if in an activity there are input variables in and output variables generated from these activities. Following the statement by Ahmed (2021) et al., "DEA can measure the efficiency of DMU with multiple inputs and multiple outputs" (Ahmed et al., 2021). Calculation of input variables and output variables with the formula constant return to scale (CRS) and variable return scale (VRS) will produce an efficient or inefficient value. So it can be said that DEA is one of the mathematical methods (Ahmed et al., 2021; Mutz et al., 2017; Ortega & Gavilan, 2013; Rosenthal & Weiss, 2017). Implementation of Data Envelopment Analysis Research with the DEA approach is usually carried out at a university to measure efficiency, but in recent years it has been used to measure the efficiency or impact of a journal. However, in this case, the variables measured are different. The reality in the field is that journals apply fees to be published. The following is a previous study using the DEA approach and its input and output variables, including:Table 1.

This study aims to determine the efficiency of journals in Indonesia indexed by SINTA ranked 1-50 contained in the SCOPUS and WoS journal databases between the number of authors who wrote the article, the team working on the Journal the cost of publication with Scientific Strength (total publication and citation) with DEA approach. The following is an image of the research design, including: Figure 1. Research design In the process of collecting scientific/research article data in journals, there are two journals not indexed in Scopus. While journals that WoS do not index, only 19 journals indexed by SINTA are indexed by WoS. The second stage is to determine DMU (Decision Making Units) variable. This variable consists of two parts, namely input variables and output variables, where this input variable is the input made by the Journal in producing the publication of scientific articles. In contrast, the output variable is the output produced by a journal. The following are the input and output variables in this study, including: Table 2. Variable Input and output research Variable Category Author Editorial team (editor, reviewer, etc.) APC (Article Publication Charge) Input Input Input Scientific Strength Output This study is aimed to to analyze the efficiency of the SINTA Indonesia-indexed journal with the DEA approach by determining the input and output variables. Based on the data above, the input variables consist of the author, the editorial team, and the APC, while the output variables in this study are scientific strength (publications and citations) generated from journals and scientific articles in the Journal. Then the variable is calculated using the DEA method to measure the efficiency of the Journal; if the value is 1 or 100%, then the Journal can be said to be efficient. Data Collection Table 3.

Journal Efficiency Analysis with Bibliometric Approach (Scientific Strength) Bibliometric analysis (scientific strength) was first introduced by Abramo et al., (2008), where to measure the scientific strength of a university or journal. Tt is not only seen from the number of publications but also the number of authors and citations obtained. The bibliometric approach (scientific strength) is commonly used to measure university efficiency by considering the input variables and resulting output variables (research). However, apart from being used to measure university research performance, a bibliometric approach (scientific strength) can also be used to measure the efficiency of a journal by taking into account the economic input indicator variable (APC/article publication charge) because several journals apply a reasonably expensive fee for publication in a journal.(Abramo & D’Angelo, 2014). The formula for calculating data in this study is Scientific Strength (SS), adopted from Abramo et al., (2011). n SS = ∑C ̅i . fi i=1 Where: = standardized citations of publication I by Journal. Citations of each publication are standardized dividing them by the median of citations of all publications of the same year ̅ C i fi= fractional count of publication i, ie, the ratio of the number of co-authors of the Journal to the total number of co-authors. SINTA-Indexed Journal Efficiency Analysis with DEA Approach In addition, bibliometric analysis (scientific strength) is used to see the scientific strength of the journal and efficiency analysis with the DEA method. The calculation test technique used is the constant return to scale (CRS) method and the variable return scale (VRS) method. This study also uses the concept of super efficiency, which was adopted by Andersen & Petersen (1993); the highest efficiency value is 1 or 100%. CRS model formula: VRS model formula: (Rusyidiana, 2013)

DEA (Data Envelopment Analysis) is an analysis to see how efficient the impact of the success of a journal in publishing a scientific article. The success of a scientific article can be seen from the number of citations obtained from publications in the published journal. The inputs to a journal in the process of publishing scientific articles in this research are the authors, editorial team (reviewer, editor, and etc.), and APC (article publication charge). In comparison, the output of a journal is to calculate the bibliometric (scientific strength) articles.

In this case, the Journal is proven effective and efficient in terms of the cost of journal publication and the impact (citations) obtained after publication in the Journal.

The results of this study show that the top journals in Indonesia indexed by Scopus and WoS, which have a DEA value of 1,000, are Operations and Supply Chain Management: An International Journal; Gadjah Mada International Journal of Business (GamaIJB); Al-Jami'ah: Journal of Islamic Studies; Tropical Animal Science Journal; Electronic Journal of Graph Theory and Applications; Journal of Tropical Forest Management. The DEA value of the top journals in Indonesia that WoS index is greater than the DEA value of the journals indexed by Scopus, but the difference is small. The lowest DEA value is 0 in the Makara Journal of Science. Research can recommend researchers determine journals for publication so that published articles can be optimally helpful, especially regarding impact citations
