The types of certifications managed by Bisma Informatika include programmer schemes, network administrators, multimedia, audio and video editing, digital marketing, project management, supply chain, mikrotik, 3D animation, and others. The use of this system helps employees in charge to serve the participant registration process. The registration procedure is done independently by the participant through the computer box available, when it has finished filling in the participant's data then the participant can directly print the form and take it to the employee on duty. After making observations for the use of the system when registration participants can be drawn some preliminary conclusions as follows. 1. The level of convenience and users' convenience when using the Bisma Informatika Certification Registration System. Users have difficulty when using the system especially when filling in the data. Many data fields are not able to be understood by the user so they must ask the officer first. 2. The diversity of registration categories in the Bisma Informatika Certification Registration System is not accommodated. Currently many parties require competency certification, so Bisma Informatika certification body has a lot of participants to follow this certification. However, the existing system still does not provide a choice of participants from the common path. 3. The instructions for filling in the columns are inconsistent, so there is a discrepancy between the instructions for filling the fields with the required data.
This indicates that the usability aspect of the registration system is not well considered. This certification registration system attaches more importance to the functional needs of the system and overrides its usability aspect. Interaction between users and the system becomes the main focus of attention in the implementation of a system. Users cannot accept the easy implementation of a system directly because there are many factors which are considered to be able to state that the implementation of the website is successful. The factors in question are the level of interest, easy, and convenience for users in utilizing the system [1].
According to Neilsen, usability is a barometer which is able to describe the quality of a system from the user's point of view. Achieving usability in a website requires a combination of planning in understanding the context of using the system as the basis for identifying and evaluating the system through testing conducted by users [2]. Website evaluation can be done with the aim of knowing if a website can be used by users effectively, efficiently and to the extent of user satisfaction level.
One of the evaluation methods of websites that can be used is the WEBUSE (Website Usability Evaluation) method. WEBUSE focuses on developing a web-based usability evaluation system with a subjective action approach that involves the participation of users to provide assessments on a website. Development of WEBUSE approach as a standard measurement of usability, with web-based questionnaire evaluation method that allows users to assess the usability of the website to be evaluated [3] [4].
Some of the researches which has been done related to WEBUSE and usability are as follows. Research conducted by Andiputra, et al. conducted an evaluation of the website of Kitabisa.com as the largest humanity fund channel website in Indonesia. This research wanted to know how the usability aspect of this website, so that users are not confused when using the website. The results showed that in all four categories obtained "Good" grades where the highest variable acquisition on content, organization, and readability variables with a score 0.77, while for the lowest variable obtained by the variable User Interface Design with a value 0.70 [5].
Dewi, et al conducted similar research using WEBUSE and Heuristic Evaluation methods to analyze the usability of the mobile application booking the inaugural taxi service. This research was conducted with the aim of knowing the usability of the application and knowing if there are difficulties experienced by users when using the application. In order to be able to know the usability problems faced by users, analysis is conducted based on test results with scenarios and questionnaires using WEBUSE questionnaires. While heuristic evaluation is used to support testing with WEBUSE in digging usability errors in applications using Nielsen heuristics conducted by selected evaluators. The results showed the usability level of this application is "Good", but there are usability issues related to the content, buttons and navigation of the application and there is a violation of heuristic principles related to error prevention. This problem is then given a recommendation of improvement so that it can be fixed and increase its usability level [6].
Aini H, et al conducted research for the evaluation of prabumulih city government website through website usability evaluation (WEBUSE) approach. WEBUSE is used to evaluate usability on the Prabumulih City Government website with Content, Organization & Readibility, Navigation & Link, User Interface Design and Performance & Effeciveness dimensions. This research aimed to determine the level of usability of the Prabumulih City Government website so that the Prabumulih City Government can provide optimal service to users. The results obtained show that performance and effectiveness are dimension of usability which plays an important role in a website, of course this can spur agencies both educational and government agencies to be able to further develop the website owned by making performance and effectiveness as the first benchmark. In other words, the higher of the level of performance and effectiveness, the better a website is [2].
This study will evaluate usability of Bisma Informatika Certification Registration Information System with Content, Organization & Readibility, Navigation & Links, User Interface Design, and Performance & Effectiveness based on WEBUSE method.

RESEARCH METHOD
Evaluation of the website of Bisma Informatika Certification Registration Information System was conducted using WEBUSE method approach. WEBUSE evaluated the website based on a website-based usability evaluation questionnaire that allowed users to assess the usefulness of the Bisma Informatics Certification Registration Information System to be evaluated. This questionnaire was divided into four categories namely Content, Organization & Readability, Navigation & Links, Design User Interface, and Performance & Effectiveness.

A. Content, Organization & Readability
Good content is content which is easy to be understood by users, clear, and well organized. A wellorganized website can provide a quick understanding for users. Meanwhile, the readability of a website is measured through whether the system is functioning correctly and provides accurate information.

B. Navigation & Links
The method used to search and access information in the website effectively and efficiently to help website users is called Navigation. Meanwhile, links function to connect users by selecting and clicking links on the hypertext page (homepage), which causes the opening of new pages. Good links should use text rather than graphics so that it is easy to understand by the user.

C. Design User Interface
User interface design is a method and procedure that requires careful consideration when designing and developing a website. Important things in designing a user interface design include setting goals, determining users and providing useful content. To ensure the best results need to consider a variety of user interface design issues and good performance for users.

D. Performance & Effectiveness
Website performance can be measured by how quickly a website performs in certain processes or transactions resulting in fast and efficient user performance. Meanwhile, effectiveness is the success of a website to produce the right information for users.
The evaluation process using WEBUSE method can be seen in Figure 1. The steps which are taken in the evaluation of Bisma Informatika certification registration system using WEBUSE method approach are as follows. e. Usability points are the mean value of each usability. Questionnaires will be prepared with several questions where there are five answer options ranging from strongly disagreeing to strongly agreeing. Each answer has its own merit value as in Table 1. The merit value obtained for each question indicator is accumulated per category and then the average value is sought. This average value for each of these categories will be considered a usability point. This usability point will then be summed up into the usability level. The relationship between usability points and usability levels can be seen in Table 2. (1) Referencing Table 2, the usability levels for each point are as follows.
1. If the X point is greater than 0, and the smaller X is equal to 0.2 then the usability level is classified as the "Bad" level. 2. If the X point is greater than 0.2 and the X is less than 0.4 then the usability level is classified as the "Poor" level. 3. If the X point is greater than 0.4 and the X is greater and the X is smaller than 0.6 then the usability level is classified as the "Moderate" level. 4. If the X point is greater than 0.6 and X is greater and the X is smaller equal to 0.8 then the usability level is classified as the "Good" level. 5. If the X point is greater than 0.8 and X is greater and X is smaller than 1.0 then the usability level is classified as "Excellent".
The questionnaire instruments given to respondents can be seen in Table 3 as follows.
