Abstract

Hosting is a place or internet service to make the website pages that you have created online and can be accessed by other people. Meanwhile, Hosting itself is an internet service that provides server resources for rent, allowing organizations or individuals to place information on the internet in the form of HTTP, FTP, EMAIL or DNS. Domain is an identifier string that is used to identify a server such as a web server or mail server on a computer network or the internet for easy access by the user. By using a domain you no longer need to remember the IP address of the server you are going to, because everything has been regulated by the Domain Name Server (DNS) so that the domain you write about will be directly connected to the IP address of the server. WebServer is a software that provides data-based services and functions to receive requests from HTTP or HTTPS on a known client and usually known as a web browser (Mozilla Firefox, Google Chrome) and to send back the results in the form of several web pages and in general. will be in the form of an HTML document.

Abstract

Detection of similarity in text documents is needed to avoid the accumulation of information in a database or file system, one way to find out plagiarism between two documents by detecting the similarity of two documents to be compared to detect plagiarism, the Shingling Algorithm is an algorithm used for near-duplicate document search processes. Shingling's algorithm is implemented to detect similarities in text documents. The ease of copying information from one document to another is one of the effects of advances in information technology. And this leads to unwanted plagiarism, so that the document detection process can be minimized properly. In this study, the test results show that the application created can detect the similarity of text documents that have gone through various manipulations, namely scaling (enlarge / reduce), rotation, cropping (partially cut), and manipulating documents.

Abstract

Comic is a work of art that is designed using a collection of still images and is complemented by a text or story. Comics are a reading book needed by children and teenagers alike. In comics, apart from the interesting content of the stories, there are also moral messages embedded in each story. However, with the development of technology, there are many comics whose stories do not educate teenagers' characters, starting from pictures and no more educational moral messages embedded in the stories. The solution drawn from this problem is by designing an Android-based comic application that can be easily accessed and understood by the public, especially teenagers. However, due to the limitations of smartphone applications to present comic episodes, string matching is needed to search for comic titles. The string matching algorithm is a string matching algorithm that looks for a string consisting of several patterns (characters) in a large amount of text. For android-based comic applications, it is designed using the Crochemore-perrin algorithm

Abstract

Of the various functions that exist in a company engaged in the business world, the function of marketing or marketing functions is a very vital and strategic function for the company concerned. The rapid development of the business world, accompanied by increasingly intense business competition, has actually strengthened the position of the marketing aspect of this vital and strategic position, Sales are the jobs most needed by the company, these 10 specialties, total vacancies for sales are 19%, followed by financial default by 18%, while IT / communication amounts to 13%. Job vacancies as sales are widely available, but lack of interest, therefore companies find it difficult to find employees in the sales department The COPRAS method assumes a direct and proportional dependence on the level of significance and utility of the alternatives in the presence of conflicting criteria. This takes into account the performance of alternatives with respect to different criteria and also the weight of the appropriate criteria. This method chooses the best decision considering the ideal and ideal solution - worst. The COPRAS method used here for decision making in the manufacturing environment adopts a six-stage procedure ranking and evaluates alternatives in terms of their level of importance and usefulness. The COPRAS method has the ability to take into account positive (favorable) and negative (unfavorable) criteria, which can be assessed separately in the evaluation process. The most important feature that makes the COPRAS method superior to other methods is that it can be used to calculate the level of alternative utility that shows the extent to which alternatives are taken for comparison

Abstract

Data security and confidentiality is one very important aspect in today's information system. The emergence of internet and multimedia technology has prompted various efforts to protect, secure, and hide data on digital files from unauthorized parties to access these files. One of the efforts to secure data and information includes using the Venigmare Cihper and the Vernam Cihper. Venigmare is an encryption that can reduce the correlation between the frequency of letters in plaintext and Ciphertext. But unfortunately this method still leaves a repeating pattern, especially if the encrypted plaintext is long enough. In this case, the role of the data encryption technique known as cryptography is very important. Cryptography is a technique for encoding data through a process of encryption and decryption with a specific key to produce encrypted data that is unknown to others. This paper will use the Vernam Cipher algorithm.

Abstract

Derivative filtering algorithm is the formulation of mathematical derivative concepts beginning with understanding the concepts of calculus applications, especially differential theory (derivatives) in digital formulations. The method used in the formulation of this theory is to seek, collect and study several theories related to differences and their applications. The derivation technique can be described as calculating the rate of brightness values in a discrete digital image, also known as an image derivation technique. Sharpening will be obtained by calculating the difference in brightness values between adjacent brightness values in the same column and row. Image is the overall result of a data recording system. Theoretically, images can be grouped into 2 (two) types, namely continuous images and discrete images (digital images). A continuous image is generated from an optical system that receives an analog signal. Example: human eye, analog camera. Meanwhile, digital images are generated through the process of digitizing continuous images. Example: digital camera.

Abstract

Determining the best BUMDes is not easy, because the decision making for the best or not the best BUMDes is still done manually without using computerization. To do this, it takes a long time and avoids mistakes in determining the best BUMDes, for that we need a decision support system that will help make decisions. The decision support system is a system that can be helpful and easy to use so that decision makers with the best alternatives make decisions in the process of determining the best BUMDes. The VIKOR method is a fairly simple method that can be used in decision making to analyze multi criteria. The VIKOR method is based on ranking and selecting from a set of existing alternatives, it can be used to rank many criteria, both qualitative and quantitative. In the VIKOR method, the best value is the smallest value, not the largest value. The calculation results of this method will be as expected if the selected alternatives meet the predetermined criteria. Thus a decision support system is needed so that it can help make the right decisions in determining the best BUMDes.
