Abstract

Steganography is the science and art of hiding information in a medium so that its existence is not detected by unauthorized parties. Media that can be used in steganography are text, images, audio, and video. However, the media that is often used is image. Various steganography tools have been developed with their respective strengths and weaknesses, such as Hide in Picture; Openstego; Image Steganography; Invisible Secret 4; S-Tools; Hide 'N' Send; Online Image Steganography, Openpuff, and others. Researchers carried out a comparative analysis of the steganography tools Openpuff and Openstego with test parameters for the quality of the images produced and time efficiency. Test the quality of the resulting image using MSE, PSNR, NCC, SSIM, and time-efficient testing seen from embedding and extraction time. Based on the research results, show that Openstego has better image quality and time efficiency compared to Openpuff. The type of image format used and the size of the embedded message can affect the quality of the resulting image and the time used. The best test results were obtained, namely MSE=0.0009, PSNR=78.5438 dB, NCC=0.999999, SSIM=0.999993, and required embedding time=0.075 second and extraction time=0.084 second. Keywords: Image Quality, Openpuff, Openstego, Steganography, Time.

Abstract

The donation application creates innovative solutions in the world of charity and charity with a design that focuses on an immersive user experience. In Indonesia, there are many online donation applications, but most of the donations given are in the form of money. Apart from money, victims of natural disasters also need assistance in the form of primary goods to meet their basic needs. Given these problems, the "Good Hands" application became a solution and was designed using the Scrum Framework method by determining User Story, Sprint Backlog, Planning, Implementation, Review, Retrospect, and Definition of Done. By incorporating the Scrum framework as a design method, this application not only creates a charity platform but also builds a deep and meaningful experience for each user. The Scrum Framework method is used as the main approach in designing the user interface (UI) and user experience (UX) of this application. This research aims to understand the context and challenges in the world of donations, exploring users' feelings, hopes, and experiences in making donations. The result of this research is a mobile-based donation application with the aim of being an intermediary for donors who will give some of their sustenance to those who need it more.
