<![CDATA[The development of today's technology has been developing very rapidly and carry a very big change because with the technology information can be obtained quickly, accurately and not limited by time and place. One o f the growing sectors in technology development is in the field of tourism which contributes to distribute information about the attractions more interactive, especially through Internet technology. Yogyakarta has a variety of tourist attractions that are so beautiful, but not many people know the various tourist attractions in the area. Information on tourist places will be known if given a forum to exchange information on the matter in the form of a website. In order to generate tourism website in accordance with the wishes of users, the necessary methods of User Centered Design (UCD) based to the user. It is intended to provide information for tourists so it will be easier to plan excursions according to what they want without hesitation choose the desired attraction. Tourism information system was built using PHP as a programming language and MySQL as a database manager. This information system design using the UCD that engage users by providing input in the form of a questionnaire. This information system contains the profiles sights, means of transportation used and distance traveled. Other facilities that can be enjoyed for information about travel agents who can serve a trip out of town, and the inn (hotel). To implement this system needs the previous test program testing and system testing and then be evaluated. The information system created is a system that is capable of displaying objects on the map and provide information on the map if the object is selected, the user can view more detailed position of an object to be searched. For site owners can perform additional object data without having to perform the construction site from scratch, in this case both the data on a map or information.

<![CDATA[The development of high-performance engineering products made from natural resources is increasing worldwide. Kenaf plants have been extensively exploited over the past few years. Chemical treatment is considered to modify the fiber surface properties. In this study, kenaf bast fibers were treated with various concentrations of NaOH with different immersed time, immersed temperature, and dried temperature. Fiber bundle tensile were performed to evaluate the effect of treatments on the fiber tensile strength. Taguchi Methods are used in order to obtain the optimal parameter which could affect the tensile strength of kenaf fibers. Three-Level Orthogonal array is used to design the experiment. Finally, the experimental results will be evaluated using analysis of variance (ANOVA). The analysis of variance (ANOVA) shows that the most significant alkali parameter is NaOH concentration, which accounts for 40.19 percent of the total. It is also found that the optimum treatment is kenaf immersed in 3 wt. percent NaOH solution for 1 hour at 33 degrees celcius and dried at 60 degrees celcius which is supported by the Fourier Transform Infrared Spectroscopy.]]>
