Abstract: Internships that are still done manually require a relatively long time so that it is not uncommon to get

complaints from anyone. So that the data processing process must adapt to the times, namely through internet

technology so that data processing can be done anywhere and anytime. Therefore, based on the existing

background, the problem is formulated, how do application developers for the Internship process and testing

using the black box method so that the application can help the process of implementing the Internship through

the media website to support the independent and independent campus program studying in the electrical

engineering department at the Manado State Polytechnic. The purpose of this study is to produce an

Apprenticeship process application that has been tested using the black box method so that the application is

expected to assist the Internship implementation process. The method used to develop the application system

is a waterfall with details of analyzing the system on an existing or ongoing apprenticeship system - Designing

new systems and software - Implementing and testing system units - System integration and testing -

Operation and maintenance. The Black box method is used to perform testing by dividing the research into 2

sections on the login function with 4 scenarios and the menu function with 10 scenarios. The result is that the

application for the internship process was successfully made according to the initial design and the testing

was successful according to a pre-determined scenario. The performance test results from 22 respondents on

average 62.3% agree and 26.6% answered strongly agree. This shows that the user can still use this

visualization model well.

1 INTRODUCTION

In 2020, Permendikbut No. 3 of 2020 was issued, the

Minister of Education and Culture issued a policy of

Merdeka Belajar – Kampus Merdeka which is a

framework to prepare students to become strong

scholars, relevant to the needs of the times and ready

to become leaders with a high national spirit. Students

are given the opportunity to enrich and improve their

competencies in the real world according to their

passions and ideals. The purpose of this government

program, of course, requires close interaction

between universities and the world of work.

Universities must know the current needs of the

company so that they can prepare students to enter the

world of work.

Article 15 paragraph 1 describes the forms of

learning activities that can be carried out inside and

outside the study program. There are 8 forms of

learning activities, one of which is internships or field

work practices carried out outside the study program

outside the campus.

In supporting the government's program of

Merdeka Learning – Merdeka Campus, Manado State

Polytechnic seeks to prepare students to be able to

prepare themselves to enter the world of work with

the Internship program. Obstacles in the form of

administrative that must be carried out in internship

activities are not small and administrative activities

that have not been computerized result in a lot of time

for their services.

The administrative process which is still done

manually takes a relatively long time so it is not

uncommon to get complaints from students.

The data processing process must adapt to the

times, namely through internet technology so that

data processing can be done anywhere and anytime.

Moreover, it is related to the current era of the Covid

19 Pandemic which allows the public to reduce mass

gatherings that involve many people. So that the

manual administration process must be reduced.

Therefore, based on the existing background, the

problem is formulated, How is the application of the

integrated Internship process in the electrical

engineering department at the Manado State

Polytechnic and testing using the blackbox method so

that the application can help the Internship

implementation process through the media website to

support the independent campus program and

independent learning.

The purpose of this study is to develop an

integrated application for the internship process in the

electrical engineering department at the Manado State

Polytechnic and testing using the blackbox method so

that the application can assist the process of

implementing the Internship through the media

website to support the independent campus program

and independent learning.

2 RESEARCH METODOLOGY

The research method that will be used to build an

integrated Apprenticeship process in the electrical

engineering department at the Manado State

Polytechnic is as follows:

Methods of field study (observation study) and

literature study (library study). This method is used

for problem identification.

The application development of the internship

process requires procedures to identify problems,

design systems using data flow diagrams and use

cases.

Waterfall method, this method is needed to build

a model of the system that will be generated in the

computer-based information system section, because

based on this method it will be a reference for

building a system based on analysis of system

requirements, functions, data flows, databases.

The system development method uses the

Waterfall method which consists of - System analysis

on existing or ongoing apprenticeship and final

project systems - New system and software design -

System unit implementation and testing - System

integration and testing - Operation and maintenance.

Functional testing uses the black box method to

see the results when the system is run whether the

system can send data from the user, whether the

server responds and displays information.

System Design, several analytical tools are

needed to assist in conducting the analysis in this

research.

The activities planned for this research are:

• Procurement of research related literature

• System analysis

• System planning

• Implementation

• Program Testing.

Research Instruments, this research requires

several instruments to support analysis and research:

Information system modeling components as follows.

Hardware consists of Laptop/PC, peripherals (printer)

and network. Software is a collection of

commands/functions written with certain rules to

instruct the computer to carry out certain tasks.

Software can be classified into Operating Systems

(Windows 7/8 and 10), Utilities (Anti Virus, Speed

Disk), and Languages (3 GL and 4 GL).

2.1 Conceptual Framework

Conceptual Framework is a form of thought

framework that can be used as an approach in solving

problem. Usually this research Framework uses a

scientific approach and demonstrates relationships

between variables in the analysis process.

Figure 1: Conceptual Framework.

2.2 System Architecture

The planning of Information services and Monitoring

tourism destinations in Southeast Minahasa District

was built to facilitate the users in this case tourists, in

search of tourist information, especially the stub

objects in southeast Minahasa Regency.

Figure 2 is architecture system consisting of three

main parts, namely client, application server and

database server.

Figure 2: Internship Process Application Architecture.

3 ANALYSIS AND DESIGN

Problem solving technique by dividing it into small

components and finally bringing it back together into

a complete and integrated system is a good technique

because it can clearly describe the system to be

designed.

3.1 System Flowchart

Fig. 3, is the result of an analysis of the system

requirements that will be developed into an

application for the internship process which consists

of 4 users, namely students, the company where the

internship is located and the academic section or

study program from which the internship student

originates.

The application system has functions to support

the internship process, such as data on internships,

daily reports, report forms, student attendance for

internships, projects.

Analysis and design are important requirements

that can be used at the beginning of system

development or when the system is revised with the

aim of getting a better system.

Figure 3: System Flowchart.

3.2 Use Case Diagram

Figure 4: Use Case Diagram.

Fig. 4, is the design of the functional requirements of

the apprentice process application system with 4

actors who can interact with the application. All

processing functionality can be used if the actor has

logged in, meaning this system is not public.

3.3 Implementation

Implementation is the result of the design of several

elements that are intentionally separated to produce a

clear logical picture of the system that aims to be

completed and put back together to be implemented

in the form of a complete application.

This section will explain the implementation of

the results of system development in the form of an

internship process application which consists of

several functions including a login function,

internship data, daily reports, report forms, student

internship attendance and projects that may be carried

out at the internship site.

Figure 5: Form Login.

Fig. 5, is a page on the application that is provided

so that interested users, namely students, companies

where internships and the academic section or study

programs originate from internship students can use

this system at the beginning of the internship, during

the internship process and at the end of the internship

process.

Like most application systems for security, a

password is used when logging in because the

password is a secret word that is used to identify who

will use and be allowed (Bentley, Lonnie D. and

Whitten Jeffrey L., 2007). Moreover, the application

system carries multi-user users like this application.

Figure 6: Homepage Admin.

Fig. 6, is part of the system that functions as a

workplace for the admin of the academic section or

study program from the internship student. The

display is made as simple as possible the same as the

front view of the other functions of this application,

so that users feel how easy it is to use the application

interface so that it is hoped that it will be easy to

understand by users and not confusing.

Figure 7: Screenshot of internship company.

Fig. 7. is one of the data processing functions that

combines company data, student internships, length

of internship, entry date, internship end date,

supervisor and status.

Fig. 8, users from the company after logging in

can see the data of students who input data to be able

to do an internship at the company and can agree or

not.

3.4 Test

Testing using the blackbox method is carried out to

find out whether the website is functioning properly

and can be implemented or not.

Testing on this application is divided into 2 parts,

namely the login section and the menu contained in

the application.

Testing is carried out when the application

follows a problem-solving technique by conducting

tests on small components and will eventually

integrate it back into a complete and integrated

system and carry out retesting.

The summary of the test can be seen in table 1 and

table 2 with the following explanation:

Table. 1, the tests carried out on the application

system of the apprenticeship process ultimately

showed that the response from the application when

logging in showed success, meaning what was

expected or the scenario in the application was

running as expected.

Table. 2, testing on the menu section for the

process of filling in data, looking at the menu for

internships, students, daily reports, report forms,

internship absences, projects, lecturer and company

data successfully according to the scenario.

This shows that the application that was built can

be used based on testing using the black box method

because in the end everything that was tested was

successful.

After doing black box testing, it is continued with

performance testing to determine the ability of the

application from the user side.

This test uses performance as a functional model

with the aim of testing the functional software.

This respondent test uses 7 questions that are in

accordance with the software model, namely easy to

use, easy to find objects on the map, appropriate color

composition, easy to read on billboards, easy to

understand writing on billboards, easy to understand

menus, easy to use menu buttons.

This test uses a non-random method by using a

purposive sampling technique.

Respondents were 22 students with scenario

students were given 10 minutes to try and then answer

the questionnaire.

Respondents' requirements are those who meet

the characteristics of the population, namely being

able to use Windows applications, student status and

have their own computer, either a laptop or a PC.

Ease of understanding the questions is also

important, therefore the questionnaire was designed

in a simple language. The measurement in this test

uses a linker scale, namely by giving a number from

1 to 5.

The test results show that there is an average of

62.3% of respondents who answered agree and there

are 2 percentages of the same answers, namely 4.5%

strongly disagree and disagree. The average

respondent answered 10.06% for undecided. The

average value of the highest percentage is to answer

agree that is 26.6%.

These results indicate that with a brief explanation

of the application without prior training, the user can

still use the visualization model easily even though

there are still shortcomings in the application, namely

it is still difficult to use, difficult to find tax objects

on the map, menus are not easy to understand and

menu buttons are not easy used.

These results indicate that there should be

improvements to the model by increasing the

performance of existing functions even though the

effect of the test time which is only 10 minutes is

given to the user to try out the application, it is felt

that it affects the interaction between users and the

application model so that it affects the performance

of the developed model.

4 CONCLUSIONS

Research shows that the application design of the

apprenticeship process can be implemented well with

procedures using the waterfall method so that it is

continued with testing using the black box method by

being divided into 2 testing sections, namely the login

and menu sections. In testing the login section there

are 4 login scenarios and all of them are successful.

While in the menu section there are 10 test scenarios

with the results all in accordance with the test

scenario or success.

The results of this study should also be continued

with various tests such as white box, performance,

effectiveness and efficiency of the application so that

the results of this application are more complete.

Without adequate training on the model, users can

still use this visualization model well as evidenced by

the results of performance testing from 22

respondents, an average of 62.3% agree and 26.6%

answered strongly agree.
