Abstract

Money is a tool for transactions. The growing of technology make payment methods is also more varied, for example with e-money. However, even there are methods like this, administrative Petra Christian University activities still use manual system so that make less practical. When e-money going to applied, there is a security aspect that must be considered. One of them is how to secure the balance that is on the card so that the balance cannot be duplicated.To make e-money payment on administrative Petra Christian University there will be make payment system with RFID (Radio Frequency Identification) with money in the card. There are 3 methods, AES, DES, 3DES with CBC and CFB mode in comparison of the speed encryption decryption, memory usage, and anti-duplication on the card. Besides there will be comparison of speed when doing top up/withdrawl balance/transaction when money stored in card and money stored in database.The test results found that there anti-duplication method successfully applied, encryption decrytion speed AES, DES, 3DES mode CBC more faster than CFB and memory usage same with all of method. Money in database have a faster process in top up/withdrawl balance while DES with CBC mode more faster in transaction.

Abstract

Sign language is one of the communication tools commonly used by people with disabilities. The alphabet sign language is a basic tool used by teachers to teach people with hearing impairment and speech impairment to recognize basic alphabet letters. However, many people find it difficult to communicate with these groups because of a lack of community insight into hand sign language. Research on sign language has experienced much progress in processing static images but is still experiencing problems due to difficulties in processing dynamic images / video given that most of the sign language is represented by body, hand, and face movements.This study uses Convolutional Neural Network (CNN) and Recurrent Neural Network (RNN) methods with video input. The CNN method will be used as a feature extraction in the spatial feature while the RNN is tasked to tolerate between frames extracted by CNN on the temporal feature.The final result to be displayed is in the form of text alphabet which is the result of the recognition of the sign language alphabet. Based on the test carried out, obtained an average accuracy value of  60.58% for all letters while real-time testing has failed because the technology used cannot sustain the architecture created.

Abstract

Toko Optik Royal adalah toko yang menjual berbagai macam jenis dan merk kacamata. Kacamata itu meliputi frame dan juga lensanya, selain itu juga menjual softlens Dalam menjalankan usahanya saat ini masih menggunakan sistem manual, semua pencatatan transaksi maupun data-datanya menggunakan kertas atau buku. Hal tersebut menyebabkan banyak terjadi kesalahan dalam pencatatan data-data transaksi sehingga data-data yang dihasilkan tidak akurat. Kesalahan data-data tersebut terjadi karena human error. Selain masih rawannya terjadi kesalahan dalam pencatatan data, sistem yang manual sangat merepotkan bila ingin melakukan pencarian data tertentu dan membutuhkan waktu yang lama. Karena menggunakan media kertas, sistem manual tersebut mempunyai kekurangan yang datanya mudah hilang. Oleh karena itu dibutuhkan suatu perancangan dan pembuatan sistem informasi yang dapat mengelola data sehingga dapat menghasilkan informasi berupa laporan dalam waktu yang cepat dan terorganisir dengan baik.Pada Skripsi ini, proses perancangan dan pembuatan program dimulai dengan mempelajari dan menganalisis sistem perusahaan saat ini, kemudian menyusun dan membuat document flow, DFD, ERD, dan tabel-tabel yang dibutuhkan serta mendesain form-form yang akan digunakan. Setelah itu, membuat program yang terdiri dari pencatatan master database, sistem pembelian, penjualan, mutasi stok, dan laporan-laporan yang diperlukan. Aplikasi yang digunakan dalam pembuatan database adalah Microsoft SQL Server 2005, untuk bahasa pemrograman menggunakan Visual Basic 6.0, dan untuk laporannya menggunakan crystal report versi 8.5.Aplikasi yang sudah dibuat meliputi master data, sistem penjualan, pembelian, mutasi stok, kartu stok, penghitungan hpp dan laba rugi, serta pembuatan laporan-laporan.

Abstract

Animasi merupakan salah satu pengolahan citra digital yang membuat sebuah objek tampak bergerak. Animasi terdiri dari kumpulan gambar dengan urutan tertentu pada sebuah timeline yang mengalami perubahan sedikit demi sedikit. Pada teknik animasi klasik atau konvensional untuk membuat sebuah objek tampak bergerak dilakukan penggambaran ulang satu per satu dari gambar semula hingga menjadi gambar akhir yang diinginkan animator sehingga memerlukan waktu yang lama.Skripsi ini bertujuan untuk membantu mempercepat proses pembuatan animasi dengan memanfaatkan teknik deformasi yang dapat menghasilkan file animasi. Metode deformasi objek gambar yang digunakan adalah Moving Least Square dengan rigid transformation. Selain objek gambar sebagai salah satu input diperlukan juga control point dan line segment untuk menentukan arah deformasi. Perhitungan tidak dilakukan pada semua pixel objek gambar namun berdasarkan grid. Proses dimulai dengan membentuk grid dan dilakukan proses deformasi berdasarkan control point dan line segment. Setelah mendapatkan grid yang baru, dilakukan inverse projective mapping untuk memetakan pixel gambar asli ke tujuan dan juga bilinear interpolation agar hasilnya menjadi smooth. Pembuatan aplikasi menggunakan bahasa pemrograman C# dengan Visual Studio 2012 sebagai IDE.Hasil pengujian menunjukkan bahwa hasil deformasi dipengaruhi oleh ukuran dari grid, nilai alpha, dan peletakkan control point dan line segment. Kecepatan proses dan kualitas berbanding terbalik terhadap banyaknya titik yang dihitung. Proses deformasi dengan control point memiliki kompleksitas waktu O(n3) sedangkan dengan line segment O(n4). Tidak ada setelan parameter yang pasti untuk dapat menghasilkan hasil yang sesuai. Pengembangan selanjutnya dapat dilakukan deformasi untuk objek 3D.
