In the era of information technology today, the development of the technology and information world is very rapid. Circumstances like this cause the agency or company will need an accurate information, so it can be reached in various fields to make a decision that is very effective and efficient. This can be used as an information medium for data collection of students who have completed education.
Speaking of education, it will not be separated from the results achieved from teaching and learning activities between students and lecturers. The results of the teaching activities are usually marked by the graduation of students who take their respective studies commonly known as alumni. The alumni data collection process that is usually done manually is no longer an option, given the vast global world. Therefore the need for websites is needed to get fast and accurate information.
The Universitas Negeri Jakarta (UNJ) has 8 faculties such as the Faculty of Educational Sciences, the Language and Arts Faculty, the Mathematics and Natural Sciences Faculty, the Faculty of Social Sciences, the Faculty of Engineering, the Faculty of Sports Science, the Faculty of Economics and the Postgraduate Program.
Considering the above, it is necessary to change the information dissemination system carried out by the agency to alumni, so that the storage of information to alumni is more complete and fast. If agencies and alumni need information about the campus world and job openings can quickly get through the website.
This happens when the institute seeks information about alumni data that has passed their education for years, agencies do not need to bother asking other alumni. This kind of event will not occur if information about alumni is more updated in the information system. Based on the above understandings, the author tries to raise these issues into a research study entitled "Development of Alumni Information Systems for Universitas Negeri Jakarta Based on Websites".
2. Information System
An information system is a system that consists of collection, input, data processing, storage, processing, control, and reporting so that information is reached from a decision to achieve the desired goals and objectives. With an information system, the community becomes easier to obtain information quickly. The development of information systems also grows faster and faster, along with the development of technology today, for example the internet.
The internet is a media that is more efficient and practical than other media such as brochures, pamphlets, newspapers, and other print media. The internet is a relationship between different local networks in an area, city, and even country, to connect multiple computers into a network group that can utilize the progress of communication media (telephone and satellite). The web is one of the internet services that is often used by organizations, educational institutions, and companies. Therefore the use of the web as a container of information systems is considered very useful to disseminate information to all alumni at the Universitas Negeri Jakarta.
3. Research Methods
The development of the alumni information system website, UNJ is Object Oriented Programming (object oriented) by using the Unified Modeling Language (UML) as a model. At the design stage to create an alumni website using the Waterfall Model Process method . The following is a stage image in the waterfall method. Waterfall model process method can be seen in Figure 1.
System development procedures
The research procedure that will be carried out based on the Waterfall stages are:
The user needs to develop the alumni information system at UNJ are:
This stage is the initial stage of making the alumni information system website. This modeling begins with looking for the needs of the entire system that will be applied in the form of software. This is very important, considering that software must be able to interact with other elements such as hardware, databases, etc. The purpose of system planning in creating websites includes:
The design stage is the stage of translating the needs into a software representation, before the implementation of the program code begins. This study uses the UML in system design and software. UML is a set of diagrams that already have standards for describing object-oriented software designs. UML diagrams used are use case diagrams, activity diagrams and class diagrams .
User interface design
The database design process is an important step so that the system is developed efficiently in the use of storage space, data access, guaranteed data integration, and easy to manipulate. Before designing a database and programming applications, it is necessary to determine what data is needed and what will be generated by the system to be built. The following system is needed for the application of a website-based alumni information system.
• User Administrator. Users are humans who are directly involved with application programs, namely administrators and alumni. The administration in question is related to user accessibility to the application system, such as Edit Password (for user login data), Edit Profile, and Role (specifying user status, as admin or normal user).
• Admin Data. This data is the main admin who manages the UNJ Alumni website.
• Alumni Data. This data consists of the main data of the Alumni Information System application, namely: alumni id, alumni name, date of birth, month of birth, year of birth, generation, status, photo of alumni, address of alumni, telephone, cellphone number, job, job address, gender, email, religion, and complete information data.
• Information Data. ata is a collection of admin & user status on the website. Information data are of two types, among others: job vacancy information data and news information data.
• Comment Data. This data is a collection of user and admin comments to the statuses contained on this website.
• Message Data. This data is a collection of messages received or sent by the admin or alumni who are logged in.
• Data Gallery. This data is a collection of photos or videos shared by the admin and user (alumni).
• User. In the database user column there is user_id from the user and admin.
Data analysis technique
Programming is the activity of making a program or a series of instructions used to set the computer to work according to each instruction. Each program undergoes individual testing to ensure that the program is error free.
• Functional Testing Feasibility testing of information systems will be tested by several examiners, including web makers, design experts and alumni of Informatics and Computer Engineering Education, Universitas Negeri Jakarta. Tests carried out alone using the Guttman scale .
• Usability Testing Data collection is done by giving a set of statements written (questionnaire) to the respondent (student) to be answered. The statement used in the questionnaire uses a 5-point Likert scale , namely:The initial step of usability testing is to provide a number of tasks or tasks that have been prepared in advance for the user when interacting with the system being tested. This task was tested to 32 correspondents including those who were ptik alumni who had seen and tested the web system www.aptik-unj.com. This task is used as a means of interaction in usability measurement.Each question from the questionnaire aims to show usability level according to user acceptance, which will be assessed in a value scale of 5 aspects in usability testing which includes five things, namely:
4. Research & Testing Results
The process of designing an alumni data collection information system uses UML diagrams. The UML diagrams used to design the Alumni Information System site in the Information and Computer Engineering Education Universitas Negeri Jakarta are use case diagrams, activity diagrams, and class diagrams. In this study the resulting product is a web-based alumni information system that will be used by 2 actors, namely admin and alumni.
Functional testing results
The total score of the functional test results is 40 (100%). Of the total score, the functional- functional system that has been tested can be declared 100% feasible.
Usability test is tested by assessing from the user's point of view, especially alumni of Universitas Negeri Jakarta. In this case the author takes a sample of 32 alumni respondents who have seen and tested the website www.aptik-unj.com.
From the results of questionnaire answers from 32 respondents then will be plotted with details of the multiplier values of each respondent's answer (SA = 5; A = 4; N = 3; D = 2; SD = 1) and the presentation value of each aspect of the answer and will be used likers scale method to see the usability ability of the web www.aptik-unj.com has been tested whether it has not been tested.
After being tested it is found to show the values of satisfaction or acceptance of each attribute. It can be seen that the percentage of each aspect is more than 80%. This can mean that www.aptik- unj.com which has been made easily recognizable and applied by the user. If adjusted again, the relationship with each of usability Learnability aspects is 87.3%, Efficiency 85.9%, Memorable 85.4%, Error 83.8% and Satisfaction 86.5%. It can be said that www.aptik-unj.com which has been created has Usability values, which are: Very good Learnability, Efficiency, Memorability, Errors, and Satisfaction (average presentation values above 80%).
From a research result, the results of product development, test results, and product revisions as well as the discussions that have been described previously, can be drawn conclusions, including:
• The development of the alumni website information system is carried out using the waterfall method with the stages of system analysis, system planning, system design, system design, system testing, system evaluation, and final products. The result of this development is a website-based agency information system product created using PHP and MySQL programming languages as data basics.
• Based on website testing using functional testing and usability testing. The results show that the website Information System website at the UNJ is 100% feasible or functioning properly and shows the values of satisfaction or acceptance of each attribute with a percentage of each aspect over 80% (Learnability 87.3%, Efficiency 85.9%, Memorable 85.4%, Error 83.8% and Satisfaction 86.5%), This can mean that the web system www.aptik-unj.com which has been made easily recognizable and applied by the user.
