Abstract

Data yang bersifat rahasia dan aman merupakan suatu hal penting yang perlu adanya sistem agar dalam menyimpan dan mengirimkannya tidak dimodifikasi oleh pihak yang tidak bertanggung jawab, baik saat data tersebut tersimpan sebagai file di dalam komputer maupun saat dikirim melalui email. Tujuan penelitian ini adalah untuk membuat aplikasi yang dapat menjaga keamanan laporan keuangan yang menerapkan algoritma RSA dan MD5 dimana RSA diterapkan untuk keamanan data laporan keuangan dan MD5 diterapkan untuk mengamankan kunci yang dibentuk oleh algoritma RSA, serta membuktikan algoritma RSA dan MD5 dapat diterapkan kedalam aplikasi. Hasil dari penelitian ini adalah aplikasi laporan keuangan dengan algoritma MD5 dan RSA yang dapat mengamankan data laporan keuangan yang telah diuji dan dinyatakan valid untuk diterapkan.

Abstract

Penentuan jadwal praktikum merupakan permasalahan yang sering dihadapi oleh perguruan tinggi. Keterbatasan jumlah kelas seringkali tidak sebanding dengan kegiatan yang dilakukan. Untuk memaksimalkan penggunaan kelas dan juga tenaga pengajar/asisten praktikum, diperlukan system penjadwalan yang baik. Dalam penelitian ini dirancang system penjadwalan praktikum menggunakan metode steepest ascent hill climbing. Penelitian ini menggunakan contoh data kelas praktikum di Fakultas Teknologi Informasi, Universitas Kristen Satya Wacana.

Abstract

Keyword merupakan kata kunci yang digunakan untuk mempermudah dalam pencarian sumber bahan pustaka. Proses pencarian melalui keyword untuk menemukan judul buku atau bahan pustaka telah menjadi kebutuhan pokok dalam suatu sistem. Namun terkadang saat pengetikan keyword, masih banyak terjadi kesalahan penulisan atau typo. Tujuan dari penelitian ini adalah membuat suatu aplikasi dalam bentuk prototype yang memberikan koreksi atau Suggestion word pada keyword sebuah bahan pustaka.Metode Jaro-winkler merupakan metode string matching yang berguna untuk mencocokan dua buah string, dengan masing-masing rumus algoritma dan juga proses yang berbeda. Pengambilan data dilakukan dengan cara mengambil data buku dari perpustakaan kemudian digunakan sebagai sample dalam proses pencarian keyword. Hasil dari penelitian ini adalah sistem yang mampu memberikan koreksi dan Suggestion word jika dalam pencarian data buku terjadi kesalahan pengetikan. Diharapkan dengan dibangunnya sistem ini dapat mempermudah pengguna perpustakaan dalam mencari buku.

Abstract

The purpose of this research is to understand the ability and to find out how much percentage of accuracy of Back Propagation algorithm in Japanese characters handwriting Hiragana’s pattern recognition. This study used the characterization of calculating a black pixel (intensity of character) and calculating the direction by applying masking diagonal left, right diagonal, vertical, and horizontal (mark direction). There were 797 letters that can be read correctly by backpropagation test equipment after applying feature combination 6 on the 7th test. Combination 6 had 5 charaterization feature 1, feature 2, feature 3, feature 4, and feature 5. Each feature was a colective feature of 9 segment which had explanation like this : feature 1 was Intensity of Character (Black), feature 2 was Mark Direction Diagonal 1 (Diag1), feature 3 was Mark Direction Diagonal 2 (Diag2), feature 4 was Mark Direction Horisontal (Horz) , and feature 5 was Mark Direction Vertical (Vert). This study revealed succeeded in proving that thebackpropagation algorithm was able to recognize Hiragana letters after achieving a success rate of accuracy above 85% which was 86.63%.S

Abstract

Javanese script is an important cultural legacy as it was widely used in a great number of old books. Digital restoration can be used to preserve these books, but the challenge is the script in these old books may be damaged due to age. Digital restoration, which involves such processes as thinning, feature extraction, and pattern matching, can be used to assist in accelerating the manual restoration process. The average success rate of this digital restoration project is only 82,07%, but it is a good start in the digital restoration of damaged print Javanese script.

Satya Wacana Christian University Library will be running smoothly when the knowledge contained in libraries is well documented. Documentation of the library will be material to members of the library that will come from members of their existing library. The presence of this documentation can solve the problems in the library associated with the provision of library materials. In solving the problem of documentation need a strategy and that strategy is a knowledge management strategy. The method used is based upon the knowledge management strategy is a process of gathering knowledge in the library and provide code on codification of knowledge can be called knowledge. So that the codification knowledge can be accessed and reused easily. Results of this study resulted in the codification knowledge in libraries Satya Wacana Christian University in Provides Library Materials that can be useful to the members involved in the library.

Abstract

Kredit koperasi adalah pinjaman dana yang diberikan oleh koperasi kepada nasabahnya berdasarkan kebutuhan maupun kriteria tertentu. Pemberian kredit kepada nasabah harus memenuhi kriteria maupun aturan tertentu. Ada 6 aspek yang harus dipertimbangkan dalam pemberian kredit, yaitu : character, collateral, condition, capacity, capital, dan area. Untuk memutuskan apakah seorang nasabah layak mendapatkan kredit atau tidak, perlu dilakukan evaluasi. Dalam penelitian ini, dirancang sebuah sistem pendukung keputusan menggunakan algoritma Iterative Dichotomizer Three untuk memudahkan koperasi melakukan evaluasi terhadap calon nasabah. Algoritma ID3 digunakan sebagai mesin inferensi untuk membantu pengambil kebijakan dalam menentukan nasabah yang layak mendapatkan kredit dan nasabah yang tidak layak mendapatkan kredit.
