Dengan teknologi yang sudah ada sekarang, banyak sekali variasi dan

metode berbeda yang dipakai untuk membuat sesuatu dengan menggabungkan

antara hardware dan software. Tugas akhir ini adalah suatu penggabungan antara

hardware (mikrokontroler, PC, keypad, LCD, RFID, kabel penghubung, dll) dan

software (VB NET, SQL Server, dan Arduino Software) dalam suatu sistem

pembayaran yang berbasiskan standarisasi internasional untuk sistem pembayaran

yang disebut ISO 8583.

VDb dan VCM adalah fitur tambahan yang terdapat didalam sistem

pembayaran, baik metoda maupun pemakaiannya. VDb digunakan untuk

menyimpan data user secara offline, ketika SQL Server digunakan untuk

menyimpan data secara online. Sedangkan VCM berupa metoda untuk

penyimpanan data sementara didalam suatu variable atau tools untuk

mempermudah proses data ketika sistem pembayaran dilakukan.

Data yang didapat ketika menguji waktu siklus yang dibutuhkan untuk

menyelesaikan sistem pembayaran sangat variatif, bergantung kepada user itu

sendiri. Waktu yang didapat untuk setiap prosesnya berbeda-beda, tetapi yang

pasti adalah waktu yang dibutuhkan lebih lama daripada waktu yang sudah

ditentukan dalam kode program menggunakan delay untuk setiap prosesnya.

Kata kunci : Virtual Database, Virtual Cache Memory, EDC, ISO 8583, Sistem

DESIGN AND REALIZATION OF EDC BASED ON

ARDUINO MICROCONTROLLER FOR PAYMENT

SYSTEM BASED ON ISO 8583

ABSTRACT

In currently technologies, there are so many variations and different

methods are used to create something that combined hardware and software. This

final project is combined hardware and software (microcontroller, PC, keypad,

LCD, RFID, connector wire, etc) in a payment system based on international

standardization for payment system is called ISO 8583.

VDb and VCM are features that rarely found on payment system, either

method or it usage. VDb is used for offline data saving, while SQL Server is used

for online data saving. Whereas VCM is a method for temporary data saving in a

variable, tools (in VB.NET likes textbox, listbox, label, etc), etc, which its

purpose is to simplified data process when payment system is running.

Data that received when testing cycle time that needed to finished payment

system is varied, depends on its user itself. Time that needed for each process are

differents, but one that certainly is time that needed are longer than time which

determined in program code using delay for each process.

Keywords : Virtual Database, Virtual Cache Memory, EDC, ISO 8583,

BAB I

PENDAHULUAN

Pada bab ini akan dibahas mengenai latar belakang, rumusan masalah, tujuan, batasan masalah.

I.1 Latar Belakang

Penggunaan Mikrokontroler Arduino sudah berkembang dengan baik dalam dunia perbankan, otomotif, dll. Dengan perkembangan yang signifikan, Mikrokontroler Arduino telah menjadi dasar teknologi yang dapat dipakai dalam area aplikasi yang luas.

Dalam dunia perbankan dipergunakan ISO 8583 untuk mengatur proses transaksi pembayaran, baik dengan menggunakan komputer maupun menggunakan EDC. Pengembangan EDC sebagai alat untuk sistem pembayaran dengan Mikrokontroler Arduino menjadi pokok penelitian dalam tugas akhir ini dengan disesuaikan terhadap beberapa pembatasan yang ada didalam ISO 8583. Meskipun berbagai sistem pembayaran sudah banyak dibuat, tidak menutup kemungkinan untuk selalu dibuat sistem pembayaran yang baru, karena sistem pembayaran yang baru pun pasti akan berbeda dari sebelumnya dengan mengikuti perkembangan teknologi atau mengikuti selera pembuatnya baik dari segi fitur, penyajian, atau program.

I.2 Rumusan Masalah

Tugas Akhir yang akan dilakukan adalah mempelajari beberapa bahasa pemrograman seperti VB. NET, SQL Server, dan C untuk dapat menemukan cara membuat program menggunakan bahasa-bahasa pemrograman tersebut.

Setelah itu, mencoba untuk mengaplikasikan program yang dibuat dalam sistem pembayaran menggunakan EDC (Electronic Data Capture) berbasis Mikrokontroler Arduino yang sesuai dengan ISO 8583.

I.3 Tujuan

Tujuan Tugas Akhir ini adalah untuk merancang dan merealisasikan sistem pembayaran dengan EDC (Electronic Data Capture) berbasis Mikrokontroler Arduino sesuai dengan ISO 8583.

I.4 Batasan Masalah

Bahasa pemrograman yang dipakai, yaitu VB.NET, SQL Server, dan C. Dengan menggunakan bahasa-bahasa pemrograman tersebut, sistem pembayaran dengan EDC (Electronic Data Capture)dapat dibuat untuk top up, top down,

balance check dan registration saja.

Untuk data yang diambil pada data pengamatan, data diambil dengan syarat

user sebagai berikut:

1. User sudah mengetahui apa yang akan dilakukan sebelum memasuki

sistem pembayaran.

2. User tidak melakukan kesalahan input saat memasuki sistem

BAB V

PENUTUP

V.1 KESIMPULAN

Sistem pembayaran telah berhasil dibuat. Menurut data hasil pengujian, waktu yang dibutuhkan untuk melakukan satu siklus bervariasi, tetapi hal yang pasti adalah waktu yang dibutuhkan lebih lama dari durasi siklus yang sudah ditentukan dalam kode program melalui delay dari masing-masing prosesnya.

V.2 SARAN

Dengan perkembangan teknologi yang terus berkembang dan pengetahuan yang terus bertambah, sistem pembayaran ini masi dapat dimaksimalkan baik dari segi keamanan, kenyamanan, fitur, dan lain-lain.
