LIBRARY SERVICE SYSTEM IN POCKET (ONLINE BOOK RESERVATION)

Abstrak: Through the library, the advancement of science and information technology also influences societal elements of life. The high level of community production makes it challenging for people to obtain library material needs, limiting engagement and library use. The Library and Archives Service of North Sumatra Province uses information and communication technology to meet user needs by developing technology-based services that facilitate effective and efficient library activities. Examples of these services include a library service system in a pocket (silapustaku) or online book reservations. To make it simpler to explain how the system functions and is utilized by the community, this study uses UML (Unified Modeling Language) modeling to examine the pocket library service system or online book reservation. A descriptive qualitative approach to the design of the UML system development is the research methodology adopted. The study's findings demonstrate a type of UML modeling design that enables each user to be viewed clearly and understood when utilizing the system. in order to build a library approach with the community and improve library performance via the use of technology.


INTRODUCTION
In general, the existence of information technology has become a big role in the world of education with the emergence of various digital creatives, along with the acceleration of the flow of information as an assimilation of globalization, including the library aspect. Currently the mastery of science, technology and information is proof of the concept of the competitive part of globalization [1]. Library is one of the public services and parties directly affected by the development of information and communication technology are managers and providers of information services [2]. There are many kinds of libraries that in their development always adjust in accommodating technological develop-ments. Libraries and librarians must be able to provide expertise in managing and providing user services [3].
Electronic communication devices such as computers greatly support library service activities in the process of management, management, and information services because they have effectiveness and efficiency that can accelerate library performance [4]. Public libraries must gradually implement aligned information technology that aims to provide excellent service to users, namely faster and more precise. It is certain that the information needs in the library are more easily obtained through access to the monitor screen provided by the library itself and cultivating the literacy ability of the community [5].
The latest development in society is the invasion of the internet and all its supporters, including search engines, social media, online multimedia, and interesting portals and websites [4]. The web itself is an inseparable part of internet resources that are very popular in today's era. The internet itself is widely used in obtaining information and even service transactions. The web itself uses a protocol called HTTP (hyperText Transfer Protocol) which runs on IP (Internet Protocol) [6], this is also starting to be applied to library operations through website pages. The web portal itself will later meet interaction needs for users and libraries so that services can be realized properly.
Due to the problem of limited time and distance with high productivity demands on an individual, it is difficult to use the library as a library material requirement for information and public education, so that user accessibility and interaction that occurs directly or indirectly in the library become hampered [7]. And related to this, efforts to meet the needs of its users at the North Sumatra Provincial Library and Archives Office are now implementing a revitalization of public library development with a library service system in pocket (silapustaku) or online book reservation. This service is through a website system that has been used by the North Sumatra Provincial Library and Archives Office to access collection lending services.
In this study, proposing the theory of innovation diffusion is an activity to communicate innovation and an important element in innovation diffusion, namely innovation, communi-cation through certain channels, time, and social systems [8]. This concept uses the library approach as a community service system that is fast, easy, practical, searches save time and energy, the library itself is required to have a high value of benefits for the information needs of the community [9]. And services as a process of some Intangible activities themselves usually occur in interactions carried out between users and librarians or employees on duty. In addition, physical resources are also needed to be solutions to problems faced by users or customers. The level of service a user receives determines the success of the service. Quality refers to the attributes of a product as a whole that support its capacity to satisfy the needs of its users. User demands should come first and end to customer pleasure and a good view of service quality [10].
So this study aims to analyze the library service system in the pocket (silapustaku) of the North Sumatra Provincial Library and Archives Office based on webside and online book reservation policies so as to produce a form of UML (Unified Modeling Languag) modeling design. In system design, researchers use Unified Modelling Languege (UML) which includes Use Case Diagrams to illustrate user interactions with the system, activity diagrams to illustrate the stages of the system process designed. To facilitate whether it has been effective in explaining the work of the system and is used / used properly by the community.

METHOD
In this study, descriptive qualita-tive methods were used with a qualitative approach in which interviews, observation, and documentation techniques were used in collecting data. Data is obtained by means of Triangulation. Researchers conduct interviews with study participants or volunteers and use broad, frequently asked questions to better understand these key symptoms. After that, the data collected is in the form of words or text for later analysis. Miles and Huberman's data analysis method, which divides data analysis into three stages of data reduction, data presentation, and conclusion drawing is the basis of the data analysis method used in this study. The findings of the analysis can be images or descriptions or can be themes. In the report later, the qualitative approach will be presented in the form of a description [11].
In the program design method, the method used is the design development method through the UML (Unified Modelling Languege) system modeling stage, this method is a method from the system to a smaller model and easily analyzes the silapustaku system so that users can understand the process of using silapustaku or book reservations [12]. UML (Unifed Model-ling Language) is used as the main tool used in software analysis and design. UML is very helpful in terms of designing software systems that will allow users to create a methodology that describes a system of objects, databases and relationships [13].
In collecting data that is the object of research is an in-depth observation of the system https://disperpusip.sumutprov.go.id/ process in conducting user interaction with the library. In addition, informant interviews were also conducted in this study using purposive sampling, where in this technique the sample was determined by considering certain things according to the wishes of the researcher or it can also be said that informants were selected first before being selected [14]. based on the criteria, namely Lely Brayana Tambunan, SH as a librarian in the field of library service network developers and Yolanda Purba as a librarian in the field of multifunction and admin of online book reservations and Agustini, Rahma Julia Windi and RD as users who have made online book reservations (silapustaku) as supporting informants in research.

RESULTS AND DISCUSSION
The library service system in pocket (Silapustaku) is an online book reservation / ordering system. From the results of interviews that have been conducted, informant Yolanda Purba explained, "Online book reservation innovation has existed since the Covid-19 period yesterday / 2019, so when users cannot come to the library, the library provides another option, namely making an online reservation where they can order books online, we find it then users just pick up to the library".
This booking is one of the activities carried out by members of the library. Increasingly advanced technology makes it easier to order books that are not only done by users and librarians face-to-face, but can also be done remotely. For example, the same as the use of Ecommerce is a form of trading transactions of goods or services using internet intermediary media [6], However, the library is a non-profit organization, so name customization is like online book reservation. The interaction of internet use in this day and age is inseparable in everyday life in meeting the needs of the community, therefore information obtained from the internet can be easily accessed on the user's mobile phone whenever and wherever the information is needed [15]. Information and communication technology is any form of activity that can be combined with each other in the manipulation, management, and transmission of information from sender to user [16].
From the results of the interview that has been conducted according to informant Lely Brayana Tambunan, SH "Silapustaku/Online reservation is containned in web-based library services, digital services that have now been implemented by the North Sumatra Provincial Library and Archives Office. The presentation of this web-based library provides a variety of services that are easily utilized by the user community and have the virtue of being devoted to becoming a member of the library both online and in person. This online book reservation service is served online by users from opening the library's webside page through https://disperpusip.sumutprov.go.id/ this online service can be accessed 24 hours the webside." The Library and Archives Office of North Sumatra Province continues to develop the service system to provide quality service quality. Development of silapustaku system as e-commerce with various android and web-based services. Each user has a different character of interaction with the system [15]. The application of this information system is very important to facilitate the operational process of the library and the use of this system is expected to be able to improve the quality of existing services properly and quality [17]. Faster service makes time more effective and efficient and will get more optimal results [18].
According to Informant Agustini as a user who has made online book reservations stated "That it is good enough to use this online book reservation service, with this silapustaku service can greatly help users in accessing to meet the information and knowledge needs of the community. In addition, more importantly for me as a student, academics certainly need good information with various types of collections that can be accessed both printed and non-print without any time and distance constraints. With this online book reservation service, the collection of library materials really provides maximum benefits and functionality to users. However, not many people know the existence and use of this online book reservation service, some of whom know this online book reservation service is only for ordering books online." As well as the results of interviews with other users, according to informant Rahma Julia Windi as a user who has made 2 online book reservations that "this online book reservation service is very good in meeting user satisfaction in terms of librarian services and book collections". And reaffirmed by RD as a user who has also made online book reservations according to informants "the online book reservation service of the North Sumatra Provincial Library and Archives Office is very helpful and makes it easier for users to still be able to borrow books with friendly librarians and fast response. It's just that it has problems with books that are not available in online catalogs" So this research succeeded in developing a UML design model on the online book reservation system. The results of this study are in the form of stages of using the online book reservation system which is adjusted to the UML mel Image 1: Image 1: Website Menu Display of the North Sumatra Library and Archives Office The description in image 1 is that there are several features or facilities provided to meet the needs of users on the website, including the first Disperpusip Profile, in this menu there is information about history, vision and mission, organizational structure, and work programs.
