Abstract

Nowadays, The development of the times is in line with the development of computer technology, which means that the storage and delivery of electronic documents is also increasing rapidly. Text files as a form of representation of electronic documents, namely all electronic information created and stored in digital form. The issue of information security in text files is a very crucial issue to be discussed. Especially if the text file sent has important and confidential information. If ignored, the information can be changed or used by irresponsible parties. Therefore, we need a technique or method to maintain the confidentiality of information known as cryptography. Cryptography has two key types, namely symmetric and asymmetric. In this study, the authors combine symmetric and asymmetric keys. The symmetric key has one key, while the asymmetric key has two keys, namely the public key and the private key. Symmetric keys are used to secure text files, while asymmetric keys are used to secure symmetric keys, a process known as hybrid cryptosystem. One of the symmetric algorithms is Vernam Cipher, while the RSA algorithm is one of the asymmetric algorithms. Secured text files are those with the *.txt file format. The results of the system testing in this study show that the time required for text file encryption is directly proportional to the character length of the text file. This means that the longer the text file used, the longer it will take to encrypt and decrypt the text file. Keywords: Cryptopraphy, Hybrid Cryptosystem, Vernam Cipher, RSA

Abstract

Pendidikan Belajar Mengaji adalah salah satu pendidikan yang sangat penting bagi umat muslim, karena mengaji merupakan sebuah ilmu yang harus dikuasai dengan benar sebagai pedoman dalam kehidupan sehari-hari. Didesa Sidodadi terdapat Yayasan Pendidikan MDTA AL-Qolam yang dipimpin oleh Ibu Rapiani dan Bapak Kusmawadi. Dimana Yayasan Pendidikan MDTA AL-Qolam adalah yayasan yang membentuk karakter anak didiknya untuk mencintai Al-Qur’an sejak dini sehingga anak-anak gemar belajar mengaji. Hasil wawancara Tim dan Pendidik bahwa telah ditemukan beberapa murid yang cenderung lambat untuk menghafalkan huruf-huruf hijaiyah. Karena kita ketahui kemampuan anak-anak tidak bisa kita sama ratakan. Dengan demikian maka pendidik sangat membutuhkan alat bantu ajar yang lebih inovatif lagi seperti game edukasi untuk membuat anak-anak tidak jenuh dan meningkatkan motivasi baru bagi anak-anak didik agar semakin aktif dalam mengaji.

Abstract

The progress of Fine Arts Learning is one type or field of education recommended by the curriculum, in the finearts curriculum there are several main lessons or pictures. In this study, there were problems in learning art,previously in learning art it was still boring by working on predetermined images, therefore it is necessary tohave an entertaining learning method that can be applied to developing technology, one of the learning methodsthat can increase student activity is the Scramble method. Scramble is an inspiring picture stacking game to addactivity. The resulting Scramble method is a simple game about randomizing images using the Android-basedscramble method. The application was built using C# programming and Unity 3D software.
