Abstract

The Law on Regional Autonomy has the impact of the Regional Government having the authority to manage the assets and regional income independently. Semarang City is an area in the Central Java Province managed by the local government of Semarang city that is required to be able to carry out autonomy well. One of the things done is the management of land and building assets owned by Semarang city government that functioned for the public interest and the implementation of city government semarang. data of government assets owned by Semarang city government recorded in Identity Card belonging to the Regional Finance and Asset Management Agency (DPKAD) there are 3,092 plots of asset managed by Regional Secretariat, Institution under Semarang City Government and management by sub-district and kelurahan area.Land assets managed by the municipal government of Semarang are currently not considered optimal. The application of the management information system for the location of the city government's land assets is planned to use the Google Maps Application Programming Interface (API), can be viewed as a solution to help the implementing officer recognize the location of the asset land and provide competitive advantages and advantages in an effort to transparency of the city government semarang on assets owned and the achievement of Semarang city to semarang be smart city.With the support of management information system application of land asset location of Semarang city government which can represent referring to location of location of real asset with remote sensing (sensing) is expected to be used effectively to manage, control and control the land asset.

Abstract

QR Code is an abbreviation of Quick Response Code. QR Code has been developedby Denso Corporation since 1994 that was first used as an identifier vehicle manufacturingsection. Along with the development needs, QR Code replaces the use of Bar Code in someareas due QR Code can be read only with digital cameras and even webcam and cameraphone.In addition to the use of QR Code as one document security device and QR Code is one of thefast recognition method. So in this study the author tries to take advantage of the QR Code asfast reading and recording of student attendance. The one of the reasons is that the presence ofstudents in each meeting is becoming one of the points of assessment, and the use of digitalcameras have become widespread in many ways, digital camera also embedded built in everylaptop which used by teachers, lecturers and instructors so that presence can be easily done byutilizing the integrated webcam in lapotop.The results of this study is, the application which can utilize QR Code image as the presencecard of students that can be read and recorded using teacher’s, lecturer’s or instructor’slaptop webcams so the process of recording attendance done easily and directly uploaded onacademic information systems

Abstract

Bagi entitas terbatas dokumen dapat bersifat rahasia dan penting, sehingga diperlukan mekanisme keamanan khhusus. Encryption with Covertext and Reordering (ECR) adalah salahsatu model keamanan dokumen berbasis teks. ECR menggunakan kunci acak untuk menghasilkan ciphertext. Kunci acak ECR dibuat secara manual. Penelitian ini bertujuan meningkatkan tingkat keamanan dokumen dengan menggunakan model enkripsi ECR. Kunci acak tabel permutasi diusulkan dalam perubahan model enkripsi ECR. Nilai acak akan dipilih secara otomatis menggunakan fungsi acak dari tabel permutasi. Dalam penelitian ini sebagai ukuran adalah entropi, yang merupakan nilai tingkat keamanan dokumen terenkripsi. Hasil eksperimen menunjukkan bahwa penyematan tabel permutasi dari kunci acak memberikan nilai entropi yang lebih baik, yang menyiratkan tingkat keamanan yang lebih baik. Penggunaan tabel permutasi kunci acak juga mempermudah penggunaan ECR untuk mengamankan dokumen

Abstract

Pertukaran informasi melalui ruang publik masih menyisakan kerentanan keamanan, sehingga perlu mekanisme pengamanan melalui proses kriptografi. Salah satu model kriptografi yang dapat bertahan hingga lebih dari 300 tahun adalah Vigenere Cipher, sebelum dipecahkan oleh Kasiski dan Friedman. Artikel ini membahas tentang perkembangan dan evlolusi Vigenere Cipher. Hingga saat ini, penggunaan Vigenere Cipher masih dapat diaplikasikan untuk mengamankan petukaran informasi dan transaksi komunikasi. Dalam perkembangannya, bentuk evolusi pada Vigenere terfokus pada tiga bagian, pengembangan dengan metode hibrid, pengembangan pada proses penerbitan kunci yang digunakan dan pengembangan pada jumlah karakter set yang digunakan pada Vigenere. Dengan pengembangan pada ketiga fokus tersebut, maka Vigenere Cipher mampu menyuguhkan tingkat keamanan yang lebih baik pada informasi yang disandikannya. Keuntungan lain adalah Vigenere Cipher dengan pengembangan ini dapat diaplikasikan dan diterima untuk pengamanan dan pertukaran infomasi pada bidang yang lebih luas
