Dipati Ukur No.112-116 Bandung, Indonesia 4 lia.warlina@email.unikom.ac.id Abstract Journal as a medium to explain the results of research. It has developed in such a way especially because of the rapid support of information and communication technology today. Various models of online-based journaling management can be easily operated by journals managers as well as writers / researchers who will include research results in the journal. It's just that with the number of journals that exist today, causing difficulties for the manager of journals to be able to promote the journals he managed, in addition to the manager of the journal sometimes difficult to get a researcher who would put his paper into the journal he manages. Meanwhile, with the number of journals that have been online, researchers will find it difficult to get information from the journals. Researchers should open their journal entries, read their profiles and publications, until they are interested to include papers in the journal. This problem is the background of the development of online journals aggregator system, which with this system will facilitate the meeting between journals, journal managers and writers or researchers. In order to develop an online journal aggregator system, a software development method is needed that directly captures the needs of its users. This study aims to implement the UCD method in the functional design and interface of the aggregator journal system. In order to determine the level of acceptance and support of prospective users of the aggregator journal system. Measurements were taken using Likert method with user acceptance preferences for 3 aspects of the system, namely: accessibility, navigation, and content aspects. The measurement results show 82% of prospective users state that the functional design and interface of the aggregator journal system can be accepted and can be developed to the next stage. Keywords: Journal, Aggregator, Online, User-Centered Design (UCD), Design 1. Introduction Journals are an important information medium for science and technology. A journal is a collection of articles or papers that are published periodically, written by the researchers to present the results of research that has been done and reviewed by the best-trusted partner. Therefore, the continuity of scientific journals becomes a very important thing for the development of science and technology in order to know the scientific development up to the latest. The development of information and communication technology (ICT) providing assistance to the journal management with the online-based journal management system. On the one hand it helps journalists in disseminating information and manage their journals, on the other hand for research with the online version of the journal makes it easy to perform a transaction related articles to be included in the journal. With the increasing number of online journals, there are a problem that is often complained by the journal managers, researchers, and public. For the LONTAR KOMPUTER VOL. 9, NO. 3 DECEMBER 2018 p-ISSN 2088-1541 DOI : 10.24843/LKJITI.2018.v09.i03.p05 e-ISSN 2541-5832 Accredited B by RISTEKDIKTI Decree No. 51/E/KPT/2017 159 journal managers, an increasing number of online journal in the field of science, an effective promotion is needed to introduce the journal to the researchers. Meanwhile, the researchers find it difficult and take a long time to find and open one by one journal web pages to view the profile of the journal which is supposed to accept the results of the research he wrote. While the public needs an access to obtain an information related to the results of research in more detail and complete in the same places. Aggregator system can be used as a solution, this is because aggregation has emerged as a valuable service to help internet users worldwide. It provides value added e-services, by collecting relevant data on the web and turns them into useful information [1]. Research on e- commerce aggregator system has been done by Raka Yusuf which allows users to search for various products without having to open one by one existing e-commerce site [2]. Other aggregator system research is done by Nydia et al, that is news aggregators who can give an automatic recommendation of any news according to their needs [3]. The aggregator can be various forms in the electronic or digital era. There are three aggregator classifications. The first type is that focusing on providing host (content host). The second type is indexing or categorizing content differently from other content (the gateway). The third type is the traditional aggregators licensed on full text content (full text aggregator) [4]. The most widely used aggregator is a news aggregator. Some research indicates the existence of news aggregator is detrimental to the original news site. Survey results show that newspapers or news websites are in a state of concern. Newspapers become depend on Facebook and Google (on search and news). News aggregator lowers traffic from newspaper sites but increases news article traffic. In the end, the user will ignore the original source [5]. The closure of google news reduces news consumption by 20% and decreases the view of other publishers by 10%. This also lowers the view on breaking news, hard news and unfavorable news [6]. However, news aggregators such as the Financial Times and The Wall Street Journal have successfully charged consumers [7]. Europeana is a library aggregator in Europe that is an organization that collects metadata from a group of content providers and distributes it. This aggregator collects material from individual organizations then standardizes file and metadata format and distributes metadata to Europeana according to SOP. This aggregator also supports content providers in terms of administration, operations, and training [8]. The same aggregator in Europe for the field of culture is the Italian Culture. Culture Italia is a national aggregator that manages culture in Italy. This cultural manager covers all sectors at the local, regional and national levels. The aggregator portal manages 2.4 million metadata from 32 private and public partners including thematic aggregators such as Italian-owned Internet Culturale library [9]. Some libraries in Indonesia have used an aggregator to facilitate librarians in universities. Aggregator as a tool to add information in library collections from various websites. Other roles of aggregators for library collections include: (a) to facilitate the user in accessing the collection without open some websites; (b) to form a positive image for the library: and (c) data entry processing to help librarians in updating references or collections [10]. UCD is used as a method in system design, due to its ease in interaction mechanisms with users who are involved in the field by utilizing user opinions, patterns of user behavior [11]. The essence of UCD's approach is that it provides a structure to assist developers in ensuring that relevant designs have been considered in a user-oriented manner [12]. Research on UCD related to system development has been done by Edwar Ali, where UCD method can trigger the creativity of the parties involved in preparing the desired software specification [13]. Based on Astri et al research, UCD can be implemented to design game-based learning applications that can improve children's learning motivation [14]. It underlies this research, which is utilizing the UCD method in developing the aggregator system of online journal. The online journals aggregator system takes the concept of a web portal that will be a meeting system between journal managers, journal, researchers, and visitor. It's will facilitate the journal managers to be able to promote the journals he managed, inviting potential researchers to include their research article and journal transactions inside it. For the researcher, online journals aggregator system will be a means to choose, like and keep journals that are considered according to the scientific field, so it will facilitate researchers to obtain information related to the journal. As for the general public, the online journals aggregator system will provide search facilities in journals, articles and authors in the same system[15]. LONTAR KOMPUTER VOL. 9, NO. 3 DECEMBER 2018 p-ISSN 2088-1541 DOI : 10.24843/LKJITI.2018.v09.i03.p05 e-ISSN 2541-5832 Accredited B by RISTEKDIKTI Decree No. 51/E/KPT/2017 160 So the purpose of journal aggregator design using UCD are (1) to build an interface system between researcher / author of a paper with journals managed by the manager of the journal, which can: (a) Facilitate the researchers / writers in searching and viewing journals in accordance with their scientific fields, discussion and journal transactions ; (b) Facilitate journal manager in promoting their journals and getting potential researchers / authors; (2) to produce an integrated system of management the journals for researchers / authors and journal manager. 2. Research Methods 2.1. Data Collection Method The method of data collection and design of information systems are as follows, shows in figure 1 :  Interview : interviews are conducted to interact directly or indirectly with parties involved in the journal community, that is journal managers, authors / researchers, and community members who need access to the journal.  Observation : this observation is done by observing directly on the research object and the developing unit. Because researchers are in a position that is also as a user, then this activity is relatively easier to do. In addition, online systems in the field of the journal into a medium to make comparisons with systems to be developed.  Literature review : reviewing the literature used, either in the form of library books, research results, and other sources. 2.2. System Design Method Using UCD The method used in the software design is the User-Centered Design (UCD) method. This method is a method that sets the user as the center of system development. The process of User-Centered Design (UCD) Method which includes 5 processes as follow: a. Plan the human-centered process : Conduct interview stages and discussions with prospective users on system design in both functional, non-functional and system interfaces. b. Specify the context of use : This stage, the researcher provides a description of the business functions carried out by the user in accordance with user needs, and describes the data and information contained in the system design.. c. Specify user and organizational requirements : Researchers describe the functional of a system developed using UML and define non-functional requirements so that the system can run well during implementation d. Product design solutions : The researcher designed the aggregator system interface according to the needs and functions of each user e. Evaluate design against user requirements : Evaluate the system design developed to potential users related to the usability of the system whether it meets expectations or not.

Indonesia One Search (IOS) is created by National Library (Perpunas) Republic of Indonesia. Through IOS, users can search public collections of libraries, museums, archives, and e-resources in Indonesia. IOS can be used to input a digital collection repository. http://onesearch.id/ http://isjd.pdii.lipi.go.id/ LONTAR KOMPUTER VOL. 9, NO. 3 DECEMBER 2018 p-ISSN 2088-1541 DOI : 10.24843/LKJITI.2018.v09.i03.p05 e-ISSN 2541-5832 Accredited B by RISTEKDIKTI Decree No. 51/E/KPT/2017 162 Figure 2. Indonesia One Search ISJD is one of the sources in the development of journal aggregators because it is the ISSN record center for journals. ISJD is developed by the Indonesian Institute of Sciences (LIPI). Through ISJD registered user may save and download articles Figure 3. Indonesia Scientific Journal Database (ISJD) The difference of a journal aggregator with Indonesia One Search (IOS) and Indonesia Scientific Journal Database (ISJD) are within the coverage of work. The journal aggregator can search, mark as favorites and interact with the journal manager. The advantage of journal aggregator is the existence of transactions between researchers / authors with the journal manager in sending the abstract to be assessed and published in the journal. 3.2. UCD Analysis for Journal Aggregator System System development method used in this research is by performing step by step on User Centered Design (UCD) method. This method focuses on the user's aspect, so there is often a misperception in pairing it with other software development methods, such as prototype, waterfall and so on. This method can stand-alone or be used in conjunction with another method. LONTAR KOMPUTER VOL. 9, NO. 3 DECEMBER 2018 p-ISSN 2088-1541 DOI : 10.24843/LKJITI.2018.v09.i03.p05 e-ISSN 2541-5832 Accredited B by RISTEKDIKTI Decree No. 51/E/KPT/2017 163 3.2.1. Plan The Human Centered Process Component At this stage, the researcher conducts interviews and discussions with prospective users, to find out what users want, namely journal researchers and managers, so that they can instill a commitment that designing an online journal aggregator system using User Centered Design (UCD) can fulfill the desires of users. 3.2.2.

The total score if the user is satisfied should (all items get a score of 5) is 5 (score) x 10 (number of statements) x 30 (number of participants) = 1500. The total score from the overall data collection = 1234. Thus the result of the preference matrix is 1234: 1500 = 82.2%. If the range is between 300-1500, the evaluation result is at GOOD intervals. Figure 9. The range of User Satisfaction Preferences 4. Conclusion The results of this study indicate that UCD can be used to produce functional designs and interfaces from online journal aggregator systems. From each stage of the user-centered design method that is carried out, it can be produced a product design that meets the user's user requirements according to the results of interviews and questionnaires. The functionality and interface of the online journal aggregator system have met the usability aspects (accessibility, navigation, and content). This is concluded from the results of functional and interface design evaluations through questionnaires using a Linkert scale which shows that the design built is at a GOOD interval, which means that the functional design and interface of the journal aggregator system can be accepted and can proceed to the next stage. For next research, in order to improve the accuracy of the development of the online journal agegator system, it is necessary to make a propototype based on the results of UCD modeling and design, but it is more intense in interacting with prospective users.
