Tama GYM is a place to exercise with a location in the field, which is comfortable and environmentally friendly. The trainer place is quite spacious and is trained by professional instructors at a very affordable entrance price. Fitness instructor is someone who serves as a guide and gives instructions to individuals or groups of people who guide members, to assist members in achieving goals based on physical health, both in physical fitness and body shape appearance by routinely doing fitness. Fitness instructors are usually called sports guides, nowadays many young people and parents are very fond of this sport. In the process of accepting Fitness Instructors, it is still done manually, namely by inputting prospective instructor data in the book so that negligence often occurs among TAMA GYM employees. The owners of TAMA GYM so far have only seen from the appearance of the Fitness Instructor itself, even though in the process of receiving Fitness Instructors must use several criteria. The criteria used in this information are appearance, character, experience, achievement and age. The AHP method is one of the methods used to solve this problem. From the research, the best alternative results fell to A9 on behalf of "simon" with a value of "0.46075".

File compression is an important aspect in the development of information technology. The demand for providing information in a short time with a large number and size of files makes compression techniques important. Image files are files that have a lot of characters so they always cause problems with memory storage. There are many algorithms developed for file compression, namely the Huffman Algorithm, Goldbach Codes Algorithm, Elias Delta Codes, Elias Gamma Codes, and Rice Codes. In this research, a comparative analysis will be carried out between the two algorithms for image compression. The analysis carried out will compare the ratio of each algorithm in the image. The analysis results obtained in this research from bitmap files are that the Elias Gamma Codes algorithm has the best compression ratio with a Ratio of Compression (RC) value of 4.17, Compression Ratio (CR) of 28.5%, Redundancy of 71.4%, and Space Saving (Ss) of 72.5% compared to the Rice Codes Algorithm with a Ratio of Compression (RC) value of 2, Compression Ratio (CR) of 54.5%, Redundancy of 46.7%, and Space Saving (Ss ) of 45.5%.

Large data sizes result in a waste of storage space required and slow data transfer processes. Compression aims to reduce the size of the data to be as small as possible. Reverse Unary is a type of lossless compression used in this research, which will be measured by Ratio of Compression (RC), Compression and Decompression. The encoding process is only done on image files with jpeg format and encodes using Reserve Unary code, then performs the compression process. From the results of the calculation of the Ration of Compression and Compression Ration of the unary Codes algorithm proves that the reserve unary code is able to reduce data up to 23% in the sense of successful compression, where the data before having a size of 72 MB and after compression the data size is obtained 47 MB.

Implementasi Metode Logarithmic Image Processing (LIP) Untuk Penajaman Warna Citra Hasil Screenshot

2025-08-01T22:15:48+07:00

Screenshots or screenshots of monitors such as smartphones, tablets and computer devices. The resulting screenshot image has a small level of smoothness and image sharpness. The level of smoothness and sharpness is said to be one of the main factors in image processing, so zooming is usually done to produce a better image directly but has a poor brightness level. The problem that often arises is that screenshot images have colors that are less bright or dark, making it difficult to understand the contents of the image. This situation will affect the sharpening of the colors in the screenshot image you want to take. Images that have less bright colors can cover up the information contained in the image. For the process of sharpening the color of a screenshot image, a method is needed so that the image can be sent properly.

Perancangan Aplikasi Kompresi File PDF Dengan Menerapkan Algoritma Stout Code

Human habits in collecting and exchanging data, one of which is in the form of PDF files, has an impact on limited storage space on computers. PDF files contain information in the form of PDF files and are widely used in the world of education, offices, companies and so on to create reports, assignments, papers, theses and others which will then be PDF files. Because the need for PDF files is very important, humans tend to collect data in the form of PDF files. In the process of exchanging data in the form of PDF files both online and offline, humans often unknowingly send and then store them in large and clear sizes, this causes the need for a large amount of storage media. The solution to solve this problem is to do compression. It is intended that the PDF file size becomes much smaller so that the PDF file transfer process is fast and can save storage space. There are several algorithms for compressing PDF files, but this study uses the Stout Code algorithm. After compressing the algorithm, then the results of the compression of the algorithm are based on several parameters such as Ratio Of Compression (RC), Compression Ratio (CR), Space Saving (SS). The results of the Stout Code compression algorithm will be compressed and a compressed PDF file will be obtained.
