INTRODUCTION
The development of technology and information is currently progressing very rapidly.
Its development is increasing day by day and the competition is getting more intense.
This happens because of the many innovations made in the context of developing The existing innovations are used to support the development of various existing fields, in this case telecommunication services, telecommunication companies to further develop and concentrate on building and achieving goals so that they can be implemented immediately.
These competent human resources come from graduates who have good quality.
Universities certainly have an important role in creating superior scholars in their fields.
To produce high-quality, ready-to-use, and skilled Human Resources (HR), the government and the private sector make efforts to educate HR before entering the world of work.
One way is through educational institutions such as schools, vocational education and universities that form high-quality human resources in all respects from the competencies taught, because of that the State Islamic University Of North Sumatera provides KP programs into the teaching and learning process in order to compete with other institutions.
other education in producing qualified and high-quality HR graduates.
Students must be introduced to the world of work early so that students can have knowledge and add insight to the field of work they are engaged in, every student must be able to have skill readiness and mental readiness before facing the real world of work.

May 2022 Systems analysis is a problem-solving technique that describes component parts by studying how well they work and interact to achieve their goals .
System analysis is the decomposition of a complete information system into its component parts with the aim of identifying and evaluating problems, opportunities, obstacles that occur and expected needs, so that desired improvements can be proposed .
System Design The flow design is made to make it easier to see what processes occur in the system.
System Design According to Pressman .
design is a series of procedures for translating the results of the analysis and a system into a programming language to describe in detail how the system components are implemented .
Flowchart can be interpreted as a tool or means that indicate the steps that must be implemented in solving a problem for computing by expressing it in a series of special graphic symbols .
The benefits that will be obtained when using flowcharts in solving computing Accustomed to think systematically and structured Easy to check and find parts invalid and verbose procedures Procedure will be easy to develop The flow of this web-based OSASE Information System is explained through a flowchart (Flowchar.
According to .
Flowchart (Flowchar.
is a method to describe the stages of problem solving by presenting certain symbols that are easy to understand, easy to use and standard.
The flowchart is as follows.
Figure 1 flowchart description Figure 1 describes some of the symbols that will be used in making a web-based Osase information system The symbol represents a process that will run on the current system and on the proposed system later.

May 2022 Context Diagram Context diagram is a diagram that consists of a process and describes the scope of a system.
Context diagram is the highest level of DFD which describes all inputs to the system or outputs from the system.
DFD describes a system that is running and is proposed logically without considering the physical environment of the data .
Figure 4 Information System Context Diagram Display Based on Figure 4.
10, the Context Diagram above can be explained as follows:
The operator performs a monitoring process on all devices monitored by the OSASE system.
The operator gets information on the location of device damage/interference which is monitored by the OSASE system.
Asman CME gets crash and activity reports on the device.

Figure 8 OSASE Web view display Figure 8 is the navbar view of the OSASE web.
In this view, it is useful to provide information to technicians if there is a problem with the device monitored by the OSASE system.
The number of STOs monitored by the OSASE web is 26 STOs in the city of Medan.
If there is trouble or damage to the equipment in each STO, the indicator in the table will turn red and show the amount of damage to the device.
Fugure 9 OSASE Web Alarm Navbar Display Figure 9 is the Alarm navbar display on the OSASE web.
This display is useful for notifying the information technician that there is damage or interference that occurs in the equipment in each STO that is monitored and detected by the OSASE system.
If there is interference or damage to the device, the data in the table will show which device has the damage and disturbance along with the location of the STO that is experiencing interference, then the admin will broadcast to every employee of the Arnet Infratel division.

This display is useful for every technician to change the user password which is required for the technician to change once a month to avoid unknown login User Interface Prototype User interface prototyping is a testing and evaluation approach, which is a crucial component of User-Centred Design (UCD) methodology, widely used in IT projects since the 1990s .
Involving users in evaluating prototypes is an important part of all iterative approaches for IT projects management, and of agile methodologies .
in particular.
Originating from User-Centred Design, prototyping has also become a popular method for user-based validating design concepts in service design and development .
