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

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

PT. Indotara Persada is a company engaged in the sale of electronic products, where electronic products are one of the people's needs such as fans, magicom, gas stoves, dispensers and so on. This company is experiencing unstable sales, so a decision is needed to overcome this. Unstable sales, the company experiences losses and does not get more profit every month in the future. In forecasting activities, forecasting methods are needed, this is in order to be able to find out in dealing with sales months for the next year to come. For this reason, the researcher uses the Laest Squares method with the aim of helping the company predict sales for the next month, so that if the predicted sales results for the next month decrease, the company will follow up such as doing promotions, giving discounts and so on. The Least Square method is a method in the form of periodic series data or time series, which requires sales data in the past to forecast future sales so that the results can be determined. Least Square is a forecasting method used to see trends from time series data. The Least Square method can be used to determine the equality of data trends which includes Time Series analysis with two cases of even and odd data

Abstract

Family Planning (KB) is a family implementation to determine the number of births. The important thing in the success of this implementation is the use of contraceptives. Contraceptives are determined based on the effect on contraceptive users. The main factor of the problem is the absence of suitable contraception for all users. With these problems a Decision Support System (DSS) is needed to determine the appropriate contraceptive method for the user's condition. In selecting decisions using the Multi-Objective Optimization by Ratio Analysis (MOORA) method. The MOORA method is used because this method can determine decisions based on criteria in the level of efficiency and the selection process is accurate but has simplicity. The criteria needed at this selection stage are price, age, menstrual history, effectiveness, time period, history of childbirth and number of children. The results obtained from this study are that, the MOORA method can choose alternatives and rank when making recommendations for contraceptives that are suitable until they are as needed. Where the alternative pill (A5) is a contraceptive for couples of childbearing age that suits their needs. The highest Yi (Max) value is 0.2249

Abstract

Pada pemilihan juara vokal grup ada banyak kendala yang dihadapi seperti kurang efektifnya hasil yang didapat untuk menentukan juara dalam perlombaan ini dikarenakan perhitungan nilai dari beberapa dewan juri sering kali salah dan terkadang juga pihak dewan juri melakukan kecurangan dalam pemberian nilai karna faktor sogokan dari peserta dan karna juri tersebut memiliki hubungan dengan peserta seperti hubungan kekelurgaan dan hubungan lainnya, sehingga peserta lain akan dirugikan. Karena permasalahan tersebut panitia pelaksana memerlukan sistem yang tepat dalam melakukan penyaringan untuk menentukan grup mana saja yang pantas mendapatkan juara dalam kompetisi ini dan sistem pendukung keputusan merupakan salah satu sistem yang dapat membantu dalam memecahkan masalah ini dengan menggunakan perbandingan metode AHP dan TOPSIS sehingga hasil yang didapatkan lebih maksimal. Pada penelitian ini bukan hanya memperbandingkan kedua metode akan tetapi menggunakan rumus tingkat kesesuaian agar bisa mengetahui metode yang paling tepat dalam melakukan penilaian pada perlombaan vocal grup dan juga akan membuat sebuah program yang akan membantu secara efektif dan efesien pada saat melakukan penilaian pada perlombaan vocal grup.
