Abstract

The development of communication technology such as the use of mobile phones based on android. Android has the capability of getting good as personal computer and it has a large storage area. Android users use it to store important data. Critical data that is stored to make various ways to membobolnya. The role of cryptography is indispensable for securing the data. Cryptography is the science to encode a message, while to keep the message or document is secure and cannot be read by those who are not entitled to use encryption. The application of encryption uses a symmetric algorithm. On the application of this method used is Simple Columnar Transposition method. Simple Columnar Transposition method by dividing plainteks into blocks with a key length (k) certain then these blocks are arranged in the form of rows and columns. The making of this application using the JAVA programming language and XML. The application is made for a mobile with Android using the Studio. This application was eventually shown on android mobile phone users. The application used to encode text/sentence, the result of encryption in the form of chipertext, and the result of decrypting plaintext form.

Abstract

The growth of the villa rental business in the Puncak Bogor area is increasing and resulting in more stringent competition in this industry. Industrial entrepreneurs try to offer many advantages of facilities and services for customers. The previous quality measurement used a questionnaire method addressed to customers. This quality measurement method results are used for evaluation as a standard for the quality level of the villas. A requirement to get a good rating is the service of the villa in standard calculations using this method. The research was conducted to produce accurate quality calculations using fuzzy implementation using the Tsukamoto method. The working record of this method represents a monotonous fuzzy set on the membership function. Research on the analysis of the calculation of rental prices for villas in the Puncak area of Bogor with the fuzzy logic of the Tsukamoto method produces inference values for all rules according to the standard value calculation for the variable value of Villa quality standards. The value is based on the variable type of room, facilities and rental price.
