<![CDATA[RSA is one of the asymmetric cryptographic algorithms that uses key pairs, namely public keys and private keys. The key length can be set, where the longer the key formation bit, the harder it is to solve because of the difficulty of factoring two very large numbers. This research applies the RSA algorithm for file encryption and decryption. Based on the research that has been done, the authors can draw conclusions, namely: RSA asymmetric cryptography algorithm can be implemented for the process of encryption and decryption of data files with an extension * .txt. ]]>

<![CDATA[The purpose of this research is to find the factors that cause tourist interest to use the services of travel agency Dior Tour is very low and arrange alternative strategies and policies that can be implemented by travel agency Dior Travel to increase the number of service users. This type of research is correlational research. Questionnaires were distributed randomly to 100 people who knew and had used the services of the Travel Dior Travel Agency. From result of analysis, it is found that 62,5% decision of purchasing tour package influenced by service quality and price. Variable quality of service, price and word of mouth together have a significant influence to decision of purchasing tour package at Dior Travel But based on partial test, word of mouth variable has no real partial effect to purchase decision. In contrast, service quality variables and price variables significantly influence partial purchasing decisions, and price variables have the most dominant influence on purchasing decisions.]]>

<![CDATA[Almost region in Indonesia produces Batik. One of the region is Lasem which popular with Batik Lasem that own characteristics. KUB Sarwo Endah is the Business Group in Lasem have still active in Batik Business. The problem occurred when KUB Sarwo Endah had a target to expand marketing field in order to increase KUB revenue. In addition, the KUB also has difficulty in predicting the number of sales, going forward, which will have an impact on the amount of KUB revenue, the number of workers and the level of demand. The Linear Regression method is used to calculate the predicted number of sales. Furthermore, the results of this forecasting will be used as input values to support a decision precisely in the Decision Support System (SPK) which will help KUB managers when it will expand its business sector. The results of the study obtained that by using the data on the number of sales in the previous period, it can be obtained the results of the prediction of the number of sales for the period or the future. Keywords: Forecasting, number of sales, Decision Support System, Batik Lasem]]>

<![CDATA[Confidentiality of a text is an important requirement for the community in this day and age to protect their privacy from people who are not entitled to it . To overcome this required an application that is able to meet the needs of the community in which the application is able to encrypt the text that is not known by others . In cryptography there are many algorithms have evolved . But in this paper we prefer to incorporate some modern and traditional algorithms are becoming a new algorithm named Caesar Cipher Algorithm Improved . The purpose of research is to make encryption and decryption application using a Caesar Cipher Improved algorithms are useful for maintaining the confidentiality of text by using a combination of traditional and modern algorithms . Analysis and the need for the user application will be developed using the methodology iteration ( iterative ) . Each step or stage in this method greatly simplifies the procedure leading analysts working in the project . The results of the analysis and design of applications using a text encryption and decryption algorithm Improved Caesar Cipher is expected to be forwarded to the implementation stage so that these applications can be applied for the purposes of the people who need to maintain confidentiality during transmission and storage of text. ]]>

<![CDATA[This research is designing a system of forecasting the number of foreign tourists in North Sumatra Province with a computerized system. Tourism is one of the important roles in the economic sector in Indonesia. The role of tourists both local and foreign influential in the development of the world of tourism in North Sumatra. But in fact the problem of transportation, preparation of services (shelter) and road density are often the main obstacles if there is an increase in the number of visitors coming to North Sumatra. To avoid the problems that have been discussed above, a system is needed to predict the number of tourists. Simple Linear regression is the method chosen in the process of planning and the system is built in the Visual Studio 2010 programming language and for data storage used by Microsoft Access. The results of the study are the forecasting system for the number of foreign tourists in North Sumatra based on the historical data of the last 10 years showing that foreign tourists who will visit in January 2016 in North Sumatra are 16,937 people.]]>

<![CDATA[In general, stores only use the data as limited to report makers. Data collected and stored sales transactions can provide useful knowledge for company management in carrying out businesses related to increased sales, for example in determining marketing strategies and to support decisions for the company. Consumers who shop at the store usually have a reason why they choose to shop at the store instead of the traditional market. Because stores can provide what they want such as comfort, cleanliness, speed and neatness of the product. Application of marketbasketanalysis techniques in the design of product layouts in stores has been carried out by several researchers, including association rule methods using Apriori algorithms to create a product placement decision support system in the shop market. & the size of the K-Means Algorithm framework has also been used to group expressigen data.]]>

<![CDATA[Implementation is an action or implementation of a plan that has been prepared carefully and in detail. Implementation is usually done after planning has been considered a fix. Cost optimization is an effort made to obtain a better final result, or it can be an attempt to obtain a smaller expenditure / effort to minimize expenses and obtain maximum profits. Method of transportation or often called stepping stone is the method used to manage distribution from sources that provide the same products in places that need them optimally. The allocation of these products must be arranged in such a way because there are differences in transportation costs (allocations) from one source to several different destinations - and from several sources to a different destination]]>

<![CDATA[Image plays a very important role as a form of information. As the convenience offered in taking, processing and storing, many people are leaving analogue images and switching to digital images. Digital image is one of the easiest forms of imagery used in terms of shipping as data, image processing and processing itself. Although an image is rich in information, but often the image we have has a decrease in the quality intensity, for example contains defects or noise (noise), the color is too contrasting or blurred. Decreasing the quality intensity, usually occurs in the process of taking or storing images (digital images). Mean filter is one of the linear filtering which functions to smooth and eliminate noise in an image that works by replacing the intensity of the pixel value with the average value of the pixel with the value of neighboring pixels. The application in this study was implemented using the VB.Net.2008 programming language and the database using Mysql.]]>
