Abstract

To speed up the process of sending secret messages, we need a medium for small messages that can still guarantee the confidentiality of the messages they contain. GIF (Graphics Interchange Format) is an image format that is one of the most commonly used formats on the web because of its small size and for encrypting the text that is sent. Encryption is carried out at the time of delivery by converting the original data into confidential data, while decryption is carried out at the time of receipt by converting the confidential data into original data. The most common way to hide messages is to use the Least Significant Bit (LSB). This research has succeeded in implementing the LSB algorithm to solve steganography on digital images in GIF format optimally

Abstract

A house is a building that functions as a residence or residence and a means of fostering a family. In rural areas there are still many residents' houses that are uninhabitable and this is caused by the standard of living of people who still live modestly and have incomes below the average, these conditions make many residents' houses uninhabitable that need to be renovated through house renovation assistance. Decision making is a system that is able to provide both problem-solving abilities and communication skills for semi-structured problems. This research system aims to design a system for determining recipients of home surgery assistance using the method, Weighted product which is one of the methods in SPK which uses a weighting method with a rating of an appraisal variable. The programming language used in making the system is PHP with a MySQL database. The results of the implementation of the system that has been made show that Parasman (A1), Hendra (A9), Ferdinand (A4) are candidates for receiving surgical assistance in Siantar Narumonda District.
