Abstract: In the current condition, business actors, especially Small and Medium Enterprises (SMEs) are increasingly

showing a tendency to utilize information technology by conducting business operational transactions using

local applications as needed. In general, transactions carried out in the SME business model are data input

directly through the PC device used. This causes the infrastructure model used for these applications to tend

to be fixed and inflexible and cannot be operated on a mobile basis or move from one place to another in the

business area. The solution to these problems is to build a transaction management system that utilizes

Wireless LAN network infrastructure modeling so that it can facilitate operational activities where employees

can serve transactions not only in one place. But by moving from one place to another around the business

area. With this application, the process of printing order notes is separated between food and beverage orders.

Benefits This application can be accessed using smaller devices such as smartphones or tablets, making it

easier to carry around mobile in the business area

1 INTRODUCTION

Today's information technology is growing very

rapidly along with the development of human needs

for flexibility and efficiency of time and thought

energy in various aspects of life. Information

technology is useful as a means to communicate,

disseminate, search for data, and the most widespread

nowadays is to use it to conduct business transactions

(Ana Rita Sampaio, Rhodri Thomas, Xavier Font,

2012). It is undeniable that information technology

has changed the behavior of economic actors in

conducting business transactions, from conventional

paper-based business to modern electronic and

digital-based business (J. Srikanth and S. Mohanavel,

2018).

Business actors, especially Small and Medium

Enterprises (SMEs) are increasingly showing a

tendency to utilize information technology by

conducting business operational transactions using

local applications as needed (V Prajová, M

Homokyová, M Horvátová, 2019). One of the

specific SMEs is the food outlet business. In a food

outlet business like this, the applications used are

generally operated on a standalone basis with PC

devices and must be connected directly to the

application provider server (Irving Reascos Paredes,

João Alvaro Carvalho, 2017). In general, transactions

carried out in the application model are inputting data

directly through the PC device used (Linus Udoh,

Ibrahim Inuwa, 2016). This causes the infrastructure

model used for these applications to tend to be fixed

and inflexible and cannot be operated on a mobile

basis or move from place to place within the business

area. As with transaction applications in general, this

modeling does not provide flexibility for business

actors who have limited employees and a fairly large

business area (Umar Bin Qushem, Akram M. Zeki,

Adamu Abubakar, 2017). The customer order process

must be recorded by the waitress then inputted

manually through the PC device used as Order Taking

(Maia A.W. and Farias P.P.M., 2019). Another

problem that arises in the SME business of food

outlets is that generally the printing of food and

beverage orders is not separated so that if there are

quite a lot of orders, it will cause difficulty in

managing the time in completing orders between food

and drinks (Holzinger A., Treitler P. and Slany W.,

2012). And one of the most importantly are the

security of transaction data via wireless lan must also

be well protected, because transaction data is

important data for a company (N. C. Kiran and G. N.

Kumar, 2011).

From the problems faced by SME business actors,

especially food outlets, this research will build a

system for transaction management that utilizes

Wireless LAN network infrastructure modeling so

that it hoped that the construction of this system can

facilitate operational activities where employees can

serve transactions not only in one place but also in

one place. By moving from place to place according

to the customer's location. As well as in the process

of printing the order note, it is possible to separate

food and beverage orders. This application can be

accessed using smaller devices such as smartphones

or tablets, making it easier to carry on mobile in the

business area.

2 RESEARCH METHOD

The development of this application can be applied to

SME businesses anywhere. The flow of the

application system that was built as shown in Figure

1 below:



Figure 1: Application System Flow.

The applications that are built are customized

according to the needs of the ongoing business

operations For details of the application system that

was built, it is shown in Figure 2 below:

Figure 2: Detail Flowchart of Wireless LAN-based

Transaction System.

The process flow system according to the flow chart

Figure 1 and Figure 2 is described as follows:

1. Waitress accesses the system via a browser.

Where the device used is a device such as a

smartphone or a tablet that can be carried

anywhere in the business area. The device

accesses the application through a Wireless LAN

Network that has been built and is intended for

applications.

2. The waitress will make an order (login required),

the waitress will access the order page and enter

the table information from the customer, then the

waitress will input the customer order list and

process the order.

3. When the order is processed by the waitress, the

order data will be saved to the database, and the

system will print the order customer in the

waitress printer, a food order note printed in the

kitchen, and a drink order note printed the bar by

direct and parallel print.

4. After the waitress makes an order, the cashier can

make payments on orders that have been inputted

by the waitress, where the cashier will access the

system via a browser and log into the system, then

the cashier will make payments according to the

Transaction Application Management through Wireless LAN for Small and Medium Enterprises

471

order information listed, and save it to the

database.

5. When payment information is saved to the

database by the cashier, the order data will be

saved to the database, and the system will print a

transaction note for the cashier.

6. In the system admin has access to manage master

data, be it product data, package data, promo data,

and user data. To manage master data the admin

will access the system via a browser (login

required) then manage the required master data

and save changes to the system.

Then for the design of the Wireless LAN Network

Framework for the application is described in Figure

3 below

Figure 3: Wireless LAN Network Design.

The network design flow process according to

Figure 3 is explained as follows

1. The application is installed on the Server device

where all transaction data is stored.

2. There is one printer in each section which used in

printing order notes and transactions.

3. In network modeling, there are two access points

that use as Wireless LAN infrastructure that

serves as a medium for communicating order data

entered by the waitress.

4. The smartphone or tablet device will be carried by

each waitress on a mobile basis or move from

place to place around the business area.

5. The ordering process is carried out through a

device brought by the waitress where the device is

connected to the Server via Wireless LAN.

6. After the order input is made by the waitress, later

the order will be printed directly in the kitchen

section for food and the Bar section for drinks.

Likewise, the waitress printer will also print all

the orders that have been inputted earlier.

7. Once there is a note printed on the Kitchen or Bar,

depending on the order. Then the Kitchen or Bar

will immediately process the order without having

to be manually informed by the waitress that there

is an incoming order.

8. For printing notes on the waitress printer, it is used

by the waitress to cross-check which orders have

been completed and brought to the customer. Thus

minimizing the order process errors.

9. When the customer wants to make a payment, he

or she is immediately invited to the cashier to

make a payment there either in cash or using a

debit/credit card. And the payment receipt will be

directly printed on the cashier's printer.

10. All transactions will be stored and recorded in the

application on the Server. If you want to print

transaction reports, the admin can do it directly

through the server or through the cashier's PC by

first logging in as Admin

For the IP Address scheme of the device used, it is

explained in table 1 below:

System testing will be carried out directly through the

tablet waitress device so that the orders entered will be

directly printed through the cashier printer in each

section, making it easier to manage customer orders.

This transaction management application's goal is to

process orders through wireless LAN so that the

waitress can move around the business area to adjust

the customer's position. Then for order management

and output notes can be arranged according to the type

of order made, such as food orders will be directly

printed in the kitchen section as well as for drink

orders will be directly printed on the bar.

3 RESULT AND EVALUATION

The results obtained from this study are transaction

management applications that can be accessed through

a wireless network from the waitress device without

any problems. This application was built using the

programming language commonly used to build an

information system is PHP with a responsive display

so that it is easy to access via web browsers on smaller

devices, such as Tablets and Mobile Phones. And for

the database using MySQL. The results of the study

are as follows:

3.1 Result

The results of this application have been implemented

at Hungrypedia Food Outlets. The figure below is the

business logo of the food outlet where this application

is used.

Figure 4: Business logo of the food outlet.

Applications are divided into 2 important parts,

that is Server Applications and Client Applications.

Server applications are placed on a PC Server located

in the office and client applications are accessed

directly via tablet devices brought directly by the

Waitress around the business area. The following is

the user interface display if the user (waitress)

accesses the system via a tablet device via a Wireless

Lan network

Figure 5: Display applications via tablet devices.

And Figure 5 below show the system interface

when accessed via a desktop computer.

Figure 6: Display the application via a desktop computer

In Figure 6 below, we can see a list of menus and

pages available on the system if accessed with an

admin account. For the administrator menu and pages,

users with cashier and waitress roles cannot have

access rights.

Figure 7: Display list of main menu admin user.

In access the system, 2 application shortcuts were

created, namely through the cashier's desktop PC and

via the waitress tablet device. This application runs

on a local network so that to access the application the

localhost system used as shown in Figure 7 below :

Figure 8: Application Shortcut via Desktop PC.

Then for system access via tablets, application

shortcuts have been created and configured to the

Transaction Management Application which remains

connected to the application server. Figure 8 below is

an application shortcut display via a tablet device

Figure 9: Application Shortcut via Tablet Waitress.

Furthermore, figure 9 shown the login display on the

application. The login option in the application

adjusts the floor position of the waitress working so

that it can do tracing if an input error occurs

Figure 10: Waitress Login Form display.

After login, the Transaction Management Application

can be used properly

3.2 Evaluation

The tests carried out were testing the connection test

from the tablet device waitress then testing the order

input according to the type of food until an order note

was printed in each section. To test the connection

from the tablet device waitress equipment to the

application server, it is shown in Figure 10 below:

Figure 11: Test the tablet waitress connection.

The results connection test evaluation shown that the

tablet device waitress connected well to the

application server, as well as testing connections to

other devices that used in this application

Furthermore, evaluation of the application itself is

carried out to ensure that the order input process can

run properly, both order input from the tablet waitress

or order input from the cashier's PC. Order input from

the cashier's PC is still needed to be an alternative to

input orders other than the tablet waitress. For order

input, it is shown in Figure 11 below:

Figure 12: Input Order PC cashier.

After inputting the order through the application,

an evaluation of the notes printed on each section is

carried out. Where for food orders the order note is

printed on the kitchen and for drink orders, the order

note is printed on the bar. Order notes that are input

474

are also printed on the waitress printer, where the

notes are used for controlling the order input by the

waitress. And for the overall order note accompanied

by the total price printed on the cashier, where the

customer will make payment after the order is

completed. The payment process is still carried out at

the cashier's PC where the payment process can be

done in cash or using a debit card through the provided

EDC machine.

The printout of the customer's note on the cashier's

PC is shown in Figure 12 below:

Figure 13: Output Bill Customer.

The results of the tests that have been carried out on

the equipment and the transaction management

application are shown in table 2 below:

application support, maintenance must be carried out,

especially Access Point as a key point in order input

wirelessly so that the operational process did not have

any problems

4 CONCLUSION

This study concludes that the Transaction

Management Application has been able to carry out

business operational transactions through wireless

LAN order input and the printing of order notes can

be separated based on the type of order. And cashier

operations have been going well. This application is

implemented into a system that will help digitalize

small and medium businesses in the future.
