| Summary: | Ordering menu in restaurant usually is done manually by writing down the
order. However, there are many problems found in such ordering system such as
there are many orders, the production of the food is done not in order because
there are many ordering notes, and there are mistakes in making the record
because of the difficulty in reading the handwriting. To overcome those problems,
a prototype of food ordering system and Short Message System (SMS)-based sale
transaction information using ATMega16 is made. This system is a prototype
system that is used to order food and inform the turnover and the availability of
food using SMS.
This system consists of three parts which are a hardware using
microcontroller ATMega16, interface software with VB.6, and SMS data
processing part using Gammu. In microcontroller part, there is a keypad 4x4
which is used to enter the order by the customers. The data that is chosen by
pushing it will be displayed in the LCD and if the code has been typed according
to the ordering format, the customers can push send. The data will be sent to the
interface software. In this part, the data will be displayed and deciphered into the
name of food, the number of the order, and the table number. After that, the data
will be saved in database access 2007. All of the transactions, incoming and
outing goods are saved in the database access to be sent to the owner of the
restaurant through SMS gateway system using Gammu. In the SMS data
processing, the incoming message will be replied automatically (auto reply). The
reply depends on the delivery message format. The writing format that can inform
the turnover by date is OMSET<space>DD/MM/YYYY and the format that can
inform the availability of the food is STOCK<space>THE NAME OF THE
FOOD.
From the system test result, it is found that the system works well. This is
proved by when code �0010002*02#03 is sent, an order of 2 fried chickens for
table number 3 is displayed in the interface software and when an SMS
containing STOCK TELOR BALADO is sent, the SMS is automatically replied
by TELOR BALADO, HARGA: 5000,KELUAR: 10, MASUK: 15, SISA: 5.
