Abstract

The research objective is to hide messages through images using the LSB (Least Significant Bit) method and Caesar Chipper and Rivest Code 4 encryption. The LSB (Least Significant Bit) method is used as a message hiding technique in steganography where hiding hidden messages is done by changing a few bits in the segment. image with a secret message. The results of this study resulted in an implementation using the Least Significant Bit (LSB) to be applied to institutions with an interest in maintaining the confidentiality of encrypted image output, changing the image file size and sound (audio) file size.Keywords:Steganography, Least Significant Bit (LSB), Caesar Chiper and RC4.

Mobile-based educational applications are expected to increase children's motivation or enthusiasm for learning at an early age to elementary school children so that they can recognize good and correct basic tajwid knowledge. The purpose of this author is to Design an educational Game of tajwid science for children aged 7-12 years to get to know the basics of recitation by using the drag and drop method with the placement of controls on random questions In this Game with the Fisher-Yates algorithm to randomize practice questions, this application displays 20 questions randomly, and applies the Flood Fill algorithm to color images or objects. This Game was made in order to increase broad knowledge and increase knowledge for children who do not understand the science of recitation in the Qur'an.

Abstract

The purpose of this study is to determine the selection of the best Stainless steel model for the Kitchen Set and can utilize the area in the kitchen room well, because the role of the kitchen set in a house is not just a room filled with spices and cooking utensils, but with a kitchen set that Ideally, the activities carried out will feel more comfortable. The method in this study uses the Analytical Hierachy Process (AHP) method where AHP is a structured technique used for organization and decision analysis and can assist in the representation of the most appropriate approach for quantifying the weights of each criterion. By using the AHP method, it produces a list of alternatives and determines the selection of models and also this system makes it easy to assess the criteria and quality of the best Stainless steel for use in Kitchen Sets.
