Abstract

The learning process is a deliberate effort by educators to impart knowledge, and create environmental systems using various methods so that students can complete learning activities effectively and efficiently and achieve optimal results. Multimedia is media that combines two or more elements consisting of text, graphics, images, photos, audio and animation in an integrated manner. Apart from making it easier for students to understand what they want to convey and so that the message can convey its meaning clearly, multimedia has the ability to stimulate the senses and allows humans to adjust to their own learning pace. This interactive learning can help users learn on their own. In addition, users are more interested in learning because of the attractive sound design and features. The purpose of this study is to determine the influence and development of multimedia learning media for students.

Abstract

A message security system to maintain the confidentiality of data information is very important. To achieve this, a security system is required to maintain the confidentiality of information. Encrypting information sent for cryptographic purposes confidentiality, integrity, authentication and irrefutable proof is one of the methods used for this purpose. Algorithm is a collection of problem-solving commands. Algorithm also has a process of repetition (iteration) and decisions that cannot be made. Vigenere cipher is one of the traditional cryptographic algorithms with multiple alphabetical substitution. PHP stands for PHP Hypertext Preprocessor. PHP is a scripting language that is commonly used to create dynamic web applications by deploying them on servers. The purpose of this research is to secure secret messages using the Vigenere Cipher algorithm using PHP.
