Abstract

In Physics subjects, so far the students have learned, among others, electronic coupling and the introduction of electronic components without any visual simulation with special media or electronic software. The availability of supporting learning media that minimally inhibits the creation of effective learning activities. To overcome the lack of availability of laboratory equipment in Citra Harapan High School Percut Sei Tuan especially in experiments with dynamic electric circuits, software called Electronic Workbench 5.12 was used which was developed in the form of a simulation. With the existence of service activities carried out, it is expected that students are able to understand electronic design, capable of assembling simple electronic components using EWB.

Abstract

The development of the computer world in the current era, the need to secure messages / data and for security in communication is very important. The author conducted this research aims to secure chat messages from client to server and vice versa. With this cryptographic technique used to convert chat messages into the form of certain codes with the intention that chat messages cannot be seen / read by anyone except people who have the right to read the chat messages. In this study, the Client and Server Message Chat encoding application is designed which implements the workings of encryption and decryption using the Spritz Algorithm. The results of this study are chat client and server message encoding applications with the Spritz algorithm that can encode confidential chat messages. This application was created using Microsoft Visual Basic 2008
