Aplikasi Pemrograman Berbasis Visual Untuk Pengamanan Undangan Terbatas Menggunakan Barcode.

Abstrak i

ABSTRAK

Teknologi sekarang ini berkembang sangat cepat dengan tujuan untuk membuat pekerjaan manusia menjadi lebih cepat, lebih mudah, dan praktis. Salah satu penggunaan teknologi saat ini yang dipakai untuk membantu pekerjaan manusia adalah komputer. Supaya pekerjaan manusia dimengerti oleh komputer, dibutuhkan penghubung antara keduanya. Program aplikasi adalah yang menghubungkannya.

Penggunaan komputer juga dapat mengurangi kesalahan yang bisa terjadi karena kelalaian manusia. Salah satunya adalah dalam melakukan pengecekan undangan yang jumlahnya sangat banyak Kesalahan yang bisa terjadi karena kelalaian adalah terlewatnya undangan untuk dicek atau salah memasukkan data pada saat membuat laporan. Sehubungan dalam hal di atas, komputer dapat digunakan untuk membantu mengatasinya. Supaya komputer dapat berinteraksi dengan pengguna, maka sebuah program aplikasi harus dibuat. Dalam tugas akhir ini, penulis mencoba membuat program untuk mengatasi masalah tersebut.

Program yang digunakan adalah Microsoft Visual Basic dan Microsoft Access. Uji coba dilakukan untuk mengetahui apakah program yang telah dibuat dapat beroperasi dengan baik. Berdasarkan uji coba yang dilakukan, didapat bahwa program yang telah dibuat dapat membantu manusia dalam melakukan pengecekan undangan.

ABSTRACT

Now days, technology grow faster and faster to make jobs faster, easier, and handy. One form of using technology to help people is computer. But to make computer understand what people want, a translator will be needed. A program application is the translator.

Use of computer will reduce the mistake that can happen because of human error. As example, when check lots of ticket. In this case, human can make mistake when checking the ticket, like pass a ticket or write different data when make a report. Because of what explained above, using computer can help them. For computer can interact with user, a program application is needed. In this final project, writer will make a program to handle the problem.

Writer use program as Microsoft Visual Basic and Microsoft Access to finish the project. Experiment will be attempted to test the program and to make program operates better. Based on the result, writer concluded that this program can help out the people when checking lots of ticket.

PENDAHULUAN

1.1Latar Belakang

Teknologi sekarang ini berkembang sangat cepat dengan tujuan untuk membuat pekerjaan manusia menjadi lebih cepat, lebih mudah, dan praktis. Dengan berkembangnya teknologi ini, manusia mengharapkan pekerjaannya dapat dilakukan dengan lebih mudah. Banyak program aplikasi komputer yang dibuat oleh manusia untuk mencapai tujuan tersebut. Salah satunya adalah untuk menangani undangan terbatas. Dengan adanya perkembangan teknologi, pemeriksaan para undangan yang terdaftar dapat dilakukan dengan cepat dan pasti serta hanya memerlukan sedikit sumber daya manusia. Hal ini akan sangat dirasakan bila terjadi pada pemeriksaan undangan yang berjumlah sangat banyak. Dengan menggunakan teknologi sekarang, undangan yang terdaftar dapat diperiksa dengan teliti, bila terdaftar maka akan dikatakan terdaftar dan bila tidak tedaftar maka akan dikatakan tidak terdaftar, berbeda bila menggunakan sumber daya manusia dimana pada saat pemerikasaan dapat terlewat sehingga undangan yang seharusnya terdaftar dikatakan tidak terdaftar. Hal tersebut dapat terjadi disebabkan oleh karena keteledoran ataupun karena terlalu sibuk mengurusi undangan yang sangat banyak sehingga ada beberapa undangan yang terabaikan atau lupa untuk dicatat dalam daftar kehadiran. Selain itu dengan aplikasi ini, laporan para undangan yang telah terdaftar dapat dibuat pada saat kapan saja dan dapat ditambahkan kapan saja. Laporan dapat dicetak kapan saja dengan menggunakan printer.

Bab I Pendahuluan 2

1.2Identifikasi Masalah

Bagaimana merealisasikan sebuah program yang mudah digunakan untuk mengolah data masukan yang berupa simbol-simbol barcode?

1.3Tujuan

Membuat program yang menggunakan simbol-simbol Barcode untuk pengamanan undangan terbatas.

1.4Pembatasan Masalah

1. Program dibuat dengan menggunakan program Microsoft Visual Basic 6.0 dan Microsoft Access 2000.

2. Menggunakan interface berupa Barcode reader.

1.5Sistematika Pembahasan

Laporan Tugas Akhir ini disusun dengan sistematika sebagai berikut :

¾ Bab I : Berisi tentang latar belakang, identifikasi masalah, tujuan, pembatasan masalah, dan sistematika pembahasan.

¾ Bab II : Berisi tentang pengenalan Visual Basic dan Access.

¾ Bab III : Berisi tentang flowchart dan cara kerja program.

¾ Bab IV : Berisi hasil-hasil pengujian dari program.

Bab V Kesimpulan dan Saran 46

BAB V

KESIMPULAN DAN SARAN

5.1Kesimpulan

ƒ Program untuk pengamanan undangan terbatas mengunakan barcode ini telah berfungsi dengan baik.

ƒ Pengundian hadiah berjalan dengan baik dan dapat mengundi dengan baik, yaitu mengundi secara acak, sehingga semua pengunjung mendapat kemungkinan untuk menang.

5.2Saran

ƒ Program dapat dikembangkan sehingga bisa berhubungan dengan komputer lain, sehingga input didapat bukan hanya dari satu komputer saja tetapi bisa dari lebih dari satu komputer.
