Abstract

Digital images that are private and confidential are very vulnerable to wiretapping by irresponsible parties, especially if the images are distributed via the internet. The act of theft and abuse of secret images of course can harm the image owner. One of the techniques to reduce the above problems is by using cryptographic techniques. Cryptographic techniques can secure images by means of digital image encryption by implementing the RC4A algorithm then using the initial keyword as input in the process carried out to generate new, more random keywords, based on the Key Schedule Algorithm. (KSA) and pseudo random generation algorithm (PRGA). To determine the comparison between the original image (PlainImage) and the original image (CipherImage), processing was carried out with MeanSquareError (MSE) and PeakSiqnalToNoiseRation (PSNR). The results of this study were digital images encrypted with the RC4A algorithm in terms of time differences and image results after encryption where the time used to encrypt is shorter than the description and the image results before encryption are not the same after encryption.

Abstract

In this final project, an encryption is created that is integrated with the existing agenda encoding application to add security to the security process on the mobile device. By using the ElGamal encryption method, it is hoped that the encryption process carried out through mobile devices will be more secure. Because, there is a public key and a private key that is only known by the user. The resulting output is ciphertext which when the user wants to read it, it is necessary to carry out the decryption process. In addition, in the encryption process for the same plaintext, different ciphertexts are obtained, but in the decryption process, the same plaintext is obtained. Thus, making the agenda safer than before.

Abstract

The success of inseminator officers is largely determined by the synergy of the roles and functions of each work unit at the Puskeswan Kota Subulussalam, as well as the activities of technical officers in the field. The role of inseminator officers is one of the main factors in the success of the program as measured by pregnancy and birth rates. Puskeswan, namely the Animal Health Center which provides services in the field of animal health in Subulussalam. The problem that occurs at the Subulussalam Health Center every year is to select the best inseminators to increase the appreciation of the performance of the inseminators, in selecting the best inseminators. still less effective. To overcome this problem, the authors want to select the best inseminator by implementing a decision support system by applying the ARAS method because this method is used for ranking so that the problem is more focused because it is based on predetermined criteria and weight values ​​so that it will get maximum results and produce better decisions. accurate in selecting the best inseminator at the Subulussalam Health Center

Abstract

In an age of increasingly sophisticated technology such as today. The need for greater storage capacity is responsible for the emergence of various compression techniques. The more file is stored, the greater the capacity. The enormous size of file results in an inefficient memory and slow-motion process of file transfer. Getting older file storage results in more and more file piling up. As technology progresses today. And thus, a growing ability to process file is utilizing a compression method that is expected to address the problem, it will be necessary to minimize storage by using Lempel Ziv Oberhumer methods to compress Advanced Audio Coding(AAC) files to narrow the size of the beets. So by applying an Lempel Ziv Oberhumer to compression the file could reduce storage capacity optimally.

Abstract

Analysis of a prediction (forecasting) is very important in a study, so that research becomes more precise and directed (Wanto and Windarto, 2017). As is the case in predicting the level of Link Aja's balance sales. This research is expected to be useful for an agency as one of the study materials in business development. A system to predict the level of sales of Link Aja balance at PT. Wahana Putra Yudha. Artificial Neural Network is a method that is able to perform a mathematical process to predict the level of sales of Link Aja Balance at PT. Wahana Putra Yudha. By using the backpropagation method, the previous data processing process is carried out which will be used as input to predict the sales level of Link Aja Balance. The data were taken from January 2021 to April 2022. January 2021 to August 2021 were used as training data, while September 2021 to April 2022 were used as test data. The training architecture model used to predict the sales level of Link Aja's Balance is: 4-2-1; 4-25-1; 4-50.1; 4-75-1; and 4-100-1. The best architecture is 4-50-1, the percentage result is 75% in each test
