Abstract

Searching images with a similarity level of two images in a set of files with the Ratcliff/Obershel and Levenshtein Distance algorithms is expected to help human work. This algorithm is one of the algorithms that can be used to find the similarity of two images by taking the rgb value of each rgb of the pixels of each image. The search process to get the image with the highest similarity. The image format that can be input into the system is a bitmap image. Bitmap mapping of computer graphic images consisting of points that form rows and columns, images consisting of dots and pixels. In the bitmap format, the image is stored as a matrix where each element is used to store color information to store color information for each pixel. This study uses the Ratcliff/Obershelp algorithm and Levenshtein Distance is an image search algorithm that is carried out by searching for matches of the same rgb value in the image. The Ratcliff/Obershelp and Levenshtein Distance algorithms are carried out in detail by displaying the query value of the image similarity level and the part that it executes and displaying images in PNG, BMP, JPEG, ICO and JPG against image similarity search.

Abstract

In the ever-growing digital era, digital content distribution has become very important in various fields, such as media, entertainment and education. The implementation of peer-topeer (P2P) computer networks has become an effective solution in increasing accessibility and efficiency in the distribution of digital content. The implementation of P2P computer networks allows digital content to be distributed in a decentralized manner, where each user acts as a host and client simultaneously. This eliminates dependency on a central server and allows content to be distributed more efficiently and quickly. In addition, with the P2P system, accessibility to digital content can be increased, especially in areas that have limited internet access. The advantage of implementing P2P computer networks in digital content distribution systems is increased accessibility. In a P2P system, content can be distributed more quickly and efficiently because there is no bottleneck at one central point. Instead, content can be distributed from multiple sources simultaneously, optimizing the use of available network capacity. This means users can download or access content at high speeds and with lower waiting times. In implementing a P2P computer network, it is necessary to consider security and network management aspects. Protection of copyright, integrity and authenticity of content is important in this system. In addition, network resources and traffic management must be managed well to maintain network quality.

Abstract

This research focuses on the development of gloves utilising flex sensors that translate hand gestures into sign language. Designed specifically for a person with a disability to communicate with others who do not understand sign language. The prototype method is used in this research with the stages of user identification, code generation and implementation, prototype testing and evaluation. The test results show that the readability rate is between 20% to 90% using SIBI gestures, the readability rate is high in some specific gestures. Integrating gloves with flex sensors creates a communication tool that is comfortable, easy and efficient to use.

Abstract

Computers have helped humans work better and help in solving problems. Computers continued to evolve and innovation continued, starting with the first very large computers and evolving into the modern, commonly used desktops. When there is a problem with the computer device, such as damage to the computer components. Most people immediately take it to a computer repair service technician. An expert system is a component of artificial intelligence. In order for computers to solve issues in the same way that professionals do, expert systems attempt to incorporate human knowledge into computers. A single technique inside the expert system is the Dempster Shafer technique. The Dempster-Shafer technique is a mathematically based approach that incorporates uncertainty and features traits of expert thought. The research was carried out by detecting computer damage based on the sound that comes out when the BIOS performs a POST (Power On Self-Test) using the Dempster-Shafer method. Users can determine the kind of damage their machine has sustained without having to visit a computer repair service provider directly by using the Dempster Shafer approach.

Abstract

A computer is a series of electronic machines consisting of thousands or even millions of components that can work together and form a neat and thorough system. Technological developments in the computer sector have progressed rapidly. Many new software have been created to help make human work easier and more practical. Almost every field has been touched by computer technology, including education. The teaching system implemented by the school does not yet have complete facilities to help students learn. Students often find it difficult because they have to study certain subjects that require a lot of study and practice, such as mathematics at elementary school level. Due to the lack of complete learning facilities at school, parents can provide interesting learning facilities by using an application at home so that their children are interested in studying at home. Creating this application goes through several stages such as: problem analysis, creating a database structure, creating a menu design, creating an application and conclusions and suggestions so that you get an application that suits your wishes and is structured. The aim of creating this application is so that elementary school age children can practice answering arithmetic questions more easily and with fun.

Abstract

Transmission of information over long distances using internet media is faced with the problem of data security and confidentiality which is one of the important aspects of data communication, both for the purpose of data security and for individual privacy. One of the communication media is to use written text because a lot of information can be conveyed through writing (text) and sometimes in the text there is confidential information. Those who want their data not to be known by unauthorized parties always try to find ways to secure the information to be communicated. The Rail Fence Cipher algorithm has an advantage over other algorithms because in the process of writing plaintext into ciphertext it can be done on any line so that it adds to the complexity of the encryption and decryption process. The Rotate13 algorithm is a development of the Caesar cipher algorithm where this algorithm changes each letter character with 13 characters in front and one behind it according to the alphabet where the 13th character shift is carried out, namely the letter A is replaced with N. So that the data is disguised and cannot be read at a glance then shift the character in the ASCII table by shifting back as much as 13 characters. In this study, encryption and decryption were carried out by combining the Rail Fence Cipher algorithm with ROT13, where the encryption and decryption process is done 2 times. Based on the experimental results, the relationship between the encryption process time and the plaintext size shows that there is an effect of processing time speed based on the number of plaintext lengths in each algorithm and based on the relationship between the encryption process time and the decryption process time, it shows that the time used does not have a significant difference.

Abstract

Medical imaging is a process of visual representation of several functions of human organs whichs used for clinical diagnosis, medical treatment, suchs x-rays which are a form of electromagnetic radiation that penetrates the human body and has the result of images of human organs like shadows on special black x-ray paper with the aim of knowing the condition human organs, suchs healthy or unhealthy lung conditions. However, lung x-ray results can provide different results from the original because they have poor quality caused by noise, blurred colors and so on, making them difficult for humans to interpret. Therefore, it’s necessary to carry out an image processing process in order to improve image quality using sharpening or getting an image display with a better form of visualization. One of the techniques used in sharpening is the Wiener filter whichs a process of improving image restoration from blurry effects based on least squares. The average percentage results that occur after applying the sharpening and Wiener methods to blurred images are 67.30%, with an average difference of 32.69%.
