Designing Web-Based DISC Psychology Personality Analysis Tests

— Using a manual system in the companies or organizations today, has many disadvantages like inefficient, wasting time, require a lot of costs, and make work difficult. By integrating a DISC personality analytical psychological test with information system, the tests are carried out with computers initially using paper, so it more economical for using less paper. More than that, the test results are done automatically check by the computer, no need to manually check by the psychologist. In addition to being effective in examining, the validation of examinations is very high because it can recover human errors.


I. INTRODUCTION
Psychology test or psychological test is a tool used to find out a person's condition [1]. This psychological test is used to measure the functions of cognitive and emotional abilities such as intelligence, interests and talents, to the personality of the person [2]. The psychological test method is a psychology research tool that is important for the ability to be tested, for the example is attitudes, talents, personality traits, and interests [3]. Personality is all kinds of varied behaviors carried out by individuals who are regulated by order and harmonization [4]. To find an individual personality, the individual can take the personality psychology test. Personality psychology tests are professional psychology proficiency which include administration, assessment, and interpretation of the support of calculating traits and styles [5].
One of the personality psychology tests is the DISC test. DISC theory is a psychological theory used to determine people's personalities based on people's emotional behavior based on their environment. DISC is divided into four personalities, there are: Dominance (D), Influence (I), Steadiness (S), and Compliance (C) [6]. The psychological test of DISC personality analysis is done on paper. Individuals who will be tested will answer on paper and then processed manually and calculated manually. But this system is less efficient and takes a lot of time.
With the internet technology, which one is web-base, communication and information services can be done easily and efficiently [7]. To use technology in an organization must have an information system. An information system in an organization provides processes and information that is useful for members and clients of the organization. With this information system, they can operate more effectively [8]. Moreover, the content validity of technology-based test examinations is higher too. Content validity is a benchmark for reflecting the content domain as expected [9]. With technology, the goal is to reduce human error in examination, so the test results more valid. Utilization of computerized technology for DISC personality analysis psychological test from previously done paper-based test is an interesting part to be explored. Because, with the many advantages of using computers for psychological tests of DISC personality analysis can develop the organization and improve work effectiveness.

A. Test
According to Freidenberg in 1995, test is a type of assessment that had specific procedures for sending information and converting information to numerical forms. The Personality Analysis Test is a Typical performance test, a test used to measure typical performance. This test is usually used for typical behavior, thinking habits, and feelings [10].

B. Phycological Test
Psychological test is a tool that are used as benchmarks for psychological aspects of the individual. Psychological test is containing interview questions that are packaged in written form [2].

C. DISC Theory
DISC theory was first put forward by William Moulton Marston, namely the expression of emotional behavior divided into four types of individuals when interacting with their environment: Dominance (D), Influence (I), Steadiness (S), and Compliance (C). Marston calls that four "primary emotions" [11]. DISC personality analysis test has been used by more than 50 million test users and published in books that have been translated in 35 languages [12]. Personalitybased DISC tests are used to classify potential members into a group, and measure productivity from members. Beside that it is also useful for psychometric measurement, leadership, and activeness in the organization [13]. Although valid, the DISC test can change because the emotional experience of an individual tends to change rather than be eternal [14].

D. Computer Assisted Test
Computer Assisted Test (CAT) is a test performed with a computer. Computers can be used in various uses as test media. Starting from the simplest, which is used to display exam questions, check test results, and give test scores [15]. So, the efficiency and validity of the answer check will increase [16].

E. Online DISC Personality Analysis Test
The web-based DISC personality analysis psychological test application is used to classify personality types based on test results. In an application test experiment to select KKL participants at Amikom Purwokerto, from the experiment, 59% of the 6 questions through the questionnaire were approved by the respondents [17].

F. Hypertext Preprocessor (PHP)
Hypertext Preprocessor (PHP) is a simple and powerful programming language designed to create HTML content. PHP can be run on many operating systems such as Linux, Solaris, FreeBSD, MacOS X and Windows. In addition, various web servers can be used, such as Apache, Microsoft IIS, and Netscape [18]. PHP can be obtained free of charge. To download PHP just by visiting the site www.php.net and applying it to the PHP editor [19].

G. Waterfall Method
Waterfall method is a method used for learning in developing a software [20]. First, the waterfall method was published by Walter Royce in 1970 [21]. The method of work of this method is that the conditions of the ongoing stage must be completed before proceeding to the next stage [22].

III. RESEARCH METHODOLOGY
The application development process used in this study uses the waterfall model. The application development began with collecting data through interviews with the Center for Applied Psychology (PPT) at Unika Soegijapranata. In addition to interviews, data searching is also done by looking for sources in books, journals, and other media that can be related to research. Continued for making application concepts. Making application concepts includes application flow, mockup, database design, and determining user roles. Continued with, making the program. The programming is done with the programming language PHP and Bootstrap Framework using the Visual Studio Code editor. The database is created using phpMyAdmin on a MySQL basis. After the program is finished, the application is tested. If the application is appropriate, the application will be implemented to the client and perform maintenance. After that, the application will be used as a research medium.
In this study, the object of research was people, with the population being psychologists, staff, and participants from the Applied Psychology Unika Soegijapranata and samples used by 30 students. The source of the primary data of this study came from questionnaires given to 30 respondents and interviews with psychologists and PPT staff and secondary data sources of this study came from journals, articles, and literature regarding the psychological test of DISC.

III. RESULTS AND DISCUSSION
The results of this application design are called online DISC personality analysis psychological tests. This application consists of 3 user roles, namely participants, psychologists, and staff. Figure 1 is the flow diagram of the application.
The use case of the DISC personality analysis psychological test application is as Figure 2.
Designing databases using Entity Relational Diagrams (ERD) from DISC personality analysis psychological test applications is as Figure 3. Psychologists have the task of giving conclusions to answers the results that have been processed by the computer. The computer processing results are calculating the accumulated answers of participants, calculating the graph automatically, and showing conclusions of the behavior and work field that is suitable for participants. Staff role is to add new users. Staff can also see user management. User management is used to view active users, edit user data, and delete users. From 30 respondents, the majority of respondents were 20 and 21 years old as much as 40%. While respondents aged 19, 22, and 24 years were 6.67%.
