I. INTRODUCTION
It is undeniable that information technology greatly affects human life, its use can be felt in various fields, ranging from transportation, health, including education such as universities [1].However, in contrast to the Internal Quality Assurance Agency STIMIK Sepuluh Nopember, Jayapura in carrying out its operations has several problems including the archiving of SPMI documents which are still done conventionally so it is very difficult if someone or a team needs these documents, archiving is done by storing documents in a cabinet that is given a code, problems will arise when someone takes the file and does not return it to its original position.With this research, it tries to provide a new solution to the STIMIK Sepuluh Nopember Jayapura college in particular, a quality assurance institution, with a computerized based system.With the existence of an information system, it is expected that archiving will gradually improve in line with the vision and mission of the quality assurance agency [3].
Several studies that design quality assurance information systems include the implementation of management information systems in improving the quality of education, in this study describes several forms of information systems that can be used in improving the quality of education [2].Another study is the quality assurance system at the Respati midwifery high school, the study concluded that it is very important to implement an information system in the quality assurance unit besides that this study states that the implementation of making applications must be realized by education administrators [3].Several other studies that use the waterfall method to design information systems include e-learning information system design, this research only conducts one type of testing using the blackbox method [4], while in this study using two testing methods, namely the blackbox method and the user acceptance test method.(UAT).The next research is the application of the waterfall method in making tracer study applications based on android [5], the difference in this research is that it is website-based and the modeling system uses data flow diagrams, whereas in previous studies using use case diagrams.

II. RESEARCH METHODS 2.1 Research Flow
There are several important stages carried out in this study, the important steps refer to the waterfall model [6], [4] The steps in this study can be seen in Figure 1.Based on Figure 1.The first step starts from analysis, the analysis stage is an initial step to describe the problems that are being experienced by the internal quality assurance agency, the second step is design, at this stage is to create a concept such as data flow diagrams and design of an information system database.suitable to be implemented in the internal quality assurance institute of STIMIK Sepuluh Nopember Jayapura, the third step is making an application, at this stage it aims to translate the results of analysis and design that have been made into a program structure using the PHP programming language.The fourth step is to test the information system that has been created, at this stage two types of testing are carried out, namely using the blackbox method and the user acceptance test (UAT) method, the blackbox method aims to find out whether the functionality of the information system can work properly, then testing using the UAT method aims to find out whether the system created can actually solve the existing problems.The fifth step is the implementation of an information system to resolve the problems that are being experienced by the internal quality assurance agency STIMIK Sepuluh Nopember Jayapura.

Data source
There are two types of data used in this study, namely primary data and secondary data, the primary data source is obtained from interviews with related parties, which are then discussed in a fucus group discussion (FGD) to obtain the real problem, secondary data comes from previous research results such as journals and books.

System Testing
This research uses two testing methods, namely testing using the blackbox method and the user acceptance test method.

a. Metode Blackbox
Testing using the black box method aims to determine the functionality of the information system to work well as for the information system testing scenario of the STIMIK Sepuluh Nopember Jayapura internal quality assurance agency can be seen in table 1.The home page of the user is hoped to be used to search and download data and information

√
Based on table 1, tests have been carried out on all the information system menus totaling 8 and based on testing the functionality of the system using the black box method as many as 8 menus as desired.

b. Metode User Acceptance Test
The test aims to find out whether the information system of the STIMIK Sepuluh Nopember Jayapura internal quality assurance institution can be used as needed by LPMI and users of the user acceptance test information system can be seen in table 2.  2, as many as 86% of the answers of respondents who answered were very correct (SB), as many as 12% of respondents who answered correctly (B) and 2% answered doubtful or neutral.

IV. CONCLUSIONS
There are several conclusions that can be drawn from research on the topic of using the waterfall method in designing an information system for the internal quality assurance institution at STIMIK Sepuluh Nopember Jayapura, including the following : In designing an information system using the waterfall method, errors tend to be reduced because all processes are carried out sequentially, starting from the process of analysis, design, system creation, testing to implementation.However, using the waterfall method also has its drawbacks, now that the time needed for system development is longer.Based on the black box test of the eight menus, the success rate of system functionality was tested with the system developer 's desire of 100%.Testing using the UAT method received a very good response from respondents 86% who answered very correctly, and 12% answered correctly, thus this information system is very feasible to be applied to the internal quality assurance agency STIMIK Sepuluh Nopember Jayapura.
