The problems that occur in chef selection have been carried out by the Head of Chef and most likely not all criteria for lexis are made judged, sometimes only a few criteria are assessed. A good restaurant certainly needs to reconsider the chef who will be accepted according to predetermined criteria. The success of a restaurant business in the background of pengelolahan in it, including the selection of a good chef will encourage the success of the restaurant. In dealing with chef selection problems conducted by the Head of Chef, a decision support system can be developed in the face of chef acceptance selection problems, namely by using the Composite Performance Index method. The criteria that will be used as an assessment are the taste of cuisine, experience, speed, creativity, education, and cleanliness. For this reason, the author hopes that the application system for receiving chef selection decisions using the Composite Performance Index method can facilitate Fishermen's Restaurant in the chef's reception selection.Keywords: Decision Support Systems, Chefs, Restaurants, Composite Performance Index
Cryptography is the science and art of keeping messages safe. In cryptography there are two main concepts, namely encryption and decryption. The encoding is first created using the clasic algorithm. this algorithm builds security on the confidentiality of the algorithm used. But this algorithm is not efficient when used to communicate with many people because the algorithm is still very simple and still very easy to solve, so that important information or data that can be easily kept secret can be recognized by other people or irresponsible people. Merkle Hellman algorithm is a cryptographic algorithm that generally encrypts twice or also called double, namely plainteks encrypted with cipher I, then the first encryption results are encrypted again with cipher II.
Postal code is an official marker element in a region in a country. The postal code was originally only used for the purpose of facilitating work at the post office to sort letters. The general public uses a lot of postal codes to do things like sending goods from one area to another through the post office service, shopping online through the official website, in that activity they are required to fill in the zip code of their destination address or shipping address. In the settlement the author uses the Zhu-Takaoka Algorithm, Zhu-Takaoka is a modified algorithm of the Boyer-Moore algorithm. Algorithm Zhu-Takaoka uses a two-dimensional array to calculate the value of the shift and do the matching from right to left. The design that is expected later this Indonesian postal code application can run well in all devices and Android smartphone versions, and this designed application is also expected to be able to help the general public in finding accurate zip codes by region. Keywords: Postal Code Indonesia, Android, Zhu-Takaoka
Uniform Resource Locator (URL) as a link between pages or as a place of a folder, data, and file makes the URL a very strategic place because it is connected directly with the database. The problem with URLs is that part of the URL is that the value of the parameter will appear in the browser's address bar so that it will provide data information that is displayed on the website page. Problems with these parameters are security holes that can be exploited by malicious users. In this research, 3DES algorithm will be applied to the formation of values from URL parameters so that the value displayed in the address bar will be the result of encryption, ciphertext. Applying the 3DES algorithm to generating URLs will provide security for the URL, because the value of the URL parameter cannot be understood by the user.Keywords: URL, security, cryptography, 3DES algorithm
The Certainty Factor method is used as a method of resolving the problem of certainty by calculating every possible value. The Certainty Factor method calculates the probable value of all the factors involved in a problem. The result of a certainty factor calculation is the result of a combination of the calculation of each factor. The combination stage of the certainty method is standard so that the calculation results will be greatly affected by the calculation of the first-factor value calculated. The certainty factor method is also known as the expert system solution method that has been used in many studies in diagnosing a problem. The influence of probability value of the first factor greatly influence the diagnosis result, therefore needed a research which discusses modifies at combination stage of method certainty factor.
The wisdom in taking a decision on a particular problem is not an easy thing, because too much consideration is taken which is expected to help give a reason certain decisions must be taken. Likewise, the handling of the problem determines the price of used laptop units on the CV. Sumber Jaya Computer Medan. The type of used laptop that is determined by the price will be easier if it is done with an application, because it has done an assessment, then the things needed are like the quality of a used laptop according to the price, processor, hard disk, memory, VGA, Old Usage. Decision support system for determining a leptop price is very appropriate to be applied for handling problems that require self-resolution of computers for processing data specifications that follow selection with efficient and accurate calculations. By using Tsukamoto Fuzzy Logic reasoning in the processing of input and output data, as well as supporting information how much ranking is very supportive in making decisions to determine the price of a used laptop.
Intisari— Sistem informasi sekarang ini merupakan hal yang tak jarang lagi dikenal oleh masyarakat. Telah menjadi salah satu aspek terpenting dalam menjalankan berbagai aspek kehidupan. Lembaga pemerintahan pun menyediakan sistem informasi yang sangat bermanfaat ditandai dengan berjalannya proses administrasi dengan baik dan cepat. Kepuasan masyarakat terhadap sistem informasi ini juga penting diketahui demi perkembangan dan kemajuan sistem informasi yang digunakan, pendapat masyarakat terhadap sistem informasi tersebut memicu perilaku masyarakat untuk menaruh kepercayaan dan penerimaan terhadap sistem informasi yang mereka gunakan. Penelitian ini dilakukan untuk mengukur penerimaan masyarakat terhadap sistem informasi dengan memberikan kuisioner kepada masyarakat dimana mereka menilai sendiri bagaimana pendapat mereka terhadap sistem informasi tersebut yang kemudian akan dianalisis menggunakan metode TAM. Variabel yang akan digunakan pada analisis TAM ini adalah perceived easy of use dengan hasil presentase 81.40%, perceived usefulness 82%, actual use presentase 79%, attitude toward using presentase 80% serta intention to us dengan presentase 51% yang menunjukan bahwa masyarakat patumbak merasa puas terhadap SIAK namun masyarakat cenderung untuk tidak menggunakannya dalam jangka panjang.
Competition of fast food restaurants at this time is getting tougher, this can be seen from the development of several fast food restaurants or fast food restaurants that exist, including Kentucky Fried Chicken, California Fried Chicken, Mc Donalds, New York Chicken, and Texas Chicken. This makes all restaurants competing in attracting consumers to buy products from the restaurant. Various efforts have been made ranging from opening branches, offering saving packages to consumers, and adding new types of food. Fast food can be interpreted as food that can be prepared to be served and consumed in a short time and can be eaten quickly. Ordering food and drinks is preferred at the current restaurant. The process of choosing food and beverage menus that are currently running at Garuda restaurants is still using menu books, menu books containing a large number of food and beverage menus, many menus are a problem for consumers because consumers find it difficult to find food and beverage menus quickly. And for the way to choose the menu itself, still see the list of food and beverage menu
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
