Abstract

USB Flash Drive is one of the most widely used storage media today, with its small shape, large capacity, and easy to carry anywhere, making USB Flash Drive the most widely used media in data exchange, along with its development, a security system is needed that can protect data stored on USB Flash Drive. The problem of this study is how to create a data security application on USB Flash Drive media? This system aims to provide data protection stored in USB Flash Drive using encryption methods, the system is created using the Delphi XE2 programming language, utilizing two Rijndael cryptographic algorithms and SHA-1 hash. The methods used in writing include data collection methods (Literature Study) and analysis methods, namely system analysis (system weaknesses, system requirements, and system feasibility). This study has succeeded in implementing a data security system for USB Flash Drive media, and testing has been carried out on the results of the implementation. Based on the results of the respondents that have been collected, it produces good response values, thus the system can provide data protection on USB Flash Drive media.

Abstract

Advances in technology and computer surveillance systems at this time have made a significant positive contribution in all fields to support and improve the performance of an order. One of the technological advances in the field of computers is the existence of a system of supervision and control of computer use in a network-based laboratory. At the Isen Mulang Palangkaraya Vocational School, there is still no computer system for monitoring and control of computer use, so students cannot supervise and control computer use during practical activities. Therefore to oversee the use of all computers in the SMK Isen Mulang Palangkaraya laboratory, it is necessary to apply an application system that functions to supervise and control the use of existing computers so that their use is only for practicum subjects not other needs.

Abstract

Permendiknas No. 16/2007 concerning Academic Qualification Standards and Teacher Competence, Pedagogical Competence of 5th / Senior High School teachers says that "High School / Vocational Teachers must utilize information and communication technology for the benefit of learning". Reinforced in Permendiknas No. 41 of 2007 concerning Process Standards, in accordance with Graduates Competency Standards and Content Standards, the learning principle used in point 13 states that "Utilization of information and communication technology to improve the efficiency and effectiveness of learning". But now when the world is entering the era of the industrial revolution 4.0. or the fourth world industrial revolution where technology has become the basis in human life the use of information and communication technology for learning must begin at the Early Childhood Education level (PAUD) in order to be more interesting and interactive and increase children's interest and curiosity in what is taught . The method of applying science and technology used is mobile technology which is very popular at the moment, namely the Android-based children's learning application as an effort to increase knowledge and understanding as well as increase the learning interest of students in grades 2, 3 and 4 of Bereng Kajang Elementary School I. The purpose of this program is to increase knowledge and understanding and increase learning interest of students in grades 2, 3 and 4 of Bereng Kajang I Elementary School on various things including letters, numbers, colors, vegetables, animals, fruits, jobs and vehicles. Both in Indonesian and English pronunciation through the implementation / dissemination of learning applications for children based on Android.
