Introduction

Libraries are inseparable from the learning of students in schools in search of science. The facilities provided by this school are very useful for all students if they can make the most of it. The collection of books in the library should always be updated at each period in accordance with the application of the education system implemented by the government. However, not all libraries apply technology in the process of library activities such as book borrowing, member registration, book search and others (Nazrudin, 2012).

The development of Information Technology began to receive a positive response from the public. Its development is not only welcomed and enjoyed by businesses and governments, but also began to penetrate in the world of education because integrated availability is increasingly important in supporting efforts to create the next generation of competitive nations (Indrajani, 2011).

At the moment at State Vocational High School X Bandung all data on the processing of library administration data does not yet have a good management application. Everything from the collection of borrowing or book returns to the creation of library administration reports is still done in writing in the bookkeeping by the administration. This often results in poor results and takes a long time (Jogiyanto, 2017).

A software library generally consists of pre-written code, classes, procedures, scripts, configuration data and more. Typically, a developer might manually add a software library to a program to achieve more functionality or to automate a process without writing code for it. For example, when developing a mathematical program or application, a developer may add a mathematics software library to the program to eliminate the need for writing complex functions. All of the available functions within a software library can just be called/used within the program body without defining them explicitly. Similarly, a compiler might automatically add a related software library to a program on run time (Kurniadi, 2000).

The value of the library lies in the reuse of standard program elements. When a program calls a library, it gets the behavior applied within that library without having to implement the behavior itself. The library encourages modular code sharing and makes code distribution easy (Kurniadi, 2000).

The behavior implemented by the library can be linked to the calling program at different phases of the program lifecycle. If the library code is accessed during the creation of the calling program, then the library is called a static library (Yin, Huang, & Jiang, 2010). The alternative is to build an executable from the calling program and distribute it, regardless of the library implementation. The library behavior is linked after the executable is called for execution, either as part of the process starting execution, or in the middle of execution. In this case the library is called a dynamic library (loaded at runtime). Dynamic libraries can be loaded and linked when preparing the program for execution, by linking. Or, in the middle of execution, the application can explicitly request the module to be loaded (Fitriani, 2020).

Most compiled languages have standard libraries, although programmers can also create their own custom libraries. Most modern software systems provide libraries that implement most of the system services. The library has set up services that require modern applications. Thus, most of the code used by modern applications is provided in these system libraries (Rinaldy & Hendrian, 2019).

Methode

Data collection techniques are carried out to obtain all information and data related to the need for completion of the final task. As for the things that are done as follows:

1. Field Studies

It is a research design that combines literature searches and surveys based on experience or case studies where researchers attempt to identify important variables (Sutanta, 2011).

a. Observation

The method is carried out to systematically identify data done either by paying attention directly or indirectly to the objects studied and taking visual data according to research needs so that no data is missed in the development of library information system at State Vocational High School X Bandung using Visual Basic 6.0.

b. Interview

Is a technique of collecting data, news, facts and information in the field that the process can be done by asking directly to the parties who can provide information about the problem that is being researched or indirectly such as making telephone, email and letter (written interview) (Amin, 2014).

2. Literature Studies

Efforts are made by the author to gather relevant information on topics and issues that will or are being researched. The information can be obtained from scientific books, research reports, scientific papers, thesis, and dissertations, regulations, statutes, yearbooks, encyclopedias and written sources both printed and electronic and internet.

Results and Discussion

A. System Design

1. Entity Relationship Diagram (ERD)

The system design that the author uses are Entity Relationship Diagram (ERD), Flowchart Document, Flowchart Program, File Structure, HIPO, Menu Design, Output Design and Program Implementation (Li & Chen, 2009).

3. Program View Design

Input design is a form of filling form design related to data processing system in the program, namely:

a. Login View Design

�Login menu there is one data that must be entered, namely User Name and Password.
