Abstract

Rapid change and growth of technology such as automatization and computerization in many types of business according to information technology communities and practitioners are demanding us to be well-prepared in facing the evolution like mobile devices especially android. Android is a mobile operating system used for touch screen based smart phones and computer tablets. The strength of GPS based android devices is in making it easy for users to access many kinds of information of tourist destinations consisting all facilities around the places. The development of this android based application is using Java Android programming language and designed by using RUP (Rational Unified Process) as the development method with Unified Modelling Language (UML) concept. The purpose of this research is to produce a Geographic Application for tourist guidance in Palembang city containing tourist objects list, public places list, transportations list, culinary places list and also other features that will help tourists to find the most effective and efficient tourist destinations. The Rasch Model measurements uses 74 respondents, to test the data using the Rasch Model measurements with the Ministep application. In the aspect of reliability, for person reliability the value is 0.89.0.90, producing a very good value. While for reliability items the value is 0.82 and 0.84 produces a good value. while the Cronbach alpha index also produces a Cronbach Alpha value yields a value of 0.93 (produces a very good value). Determination of sample size uses the Item Measure table based on the accuracy of confidence measurements (95%).
