<![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. By making this system the objects displayed on the map always updates that facilitate and assist the user in doing excursions in Yogyakarta.]]>

<![CDATA[Metode Median Filter adalah salah satu metode perbaikan kualitas citra pada domain spatial. Domain spatial memiliki kelebihan pada hasil perbaikan karena perbaikan citra dilakukan per-pixel. Karena perbaikan citra dilakukan terhadap pixel, metode Median Filter memiliki komputasi yang tinggi dan waktu eksekusi yang lama.Dengan melakukan penyeleksian terhadap pixel yang perlu diperbaiki dapat mengurangi waktu proses perbaikan dan meningkatkan kualitas citra karena pixel yang sudah benar, tidak perlu diperbaiki. Pengukuran kualitas citra dilakukan menggunakan Peak Signal to Noise Ratio (PSNR) dengan membandingkan nilai citra asli dengan citra hasil perbaikan. Nilai PSNR ideal untuk disebut sebagai citra yang baik adalah 30dB.Kualitas Citra metode Median Filter dengan penyeleksian memiliki kenaikan nilai PSNR sebesar 5.6% dan memiliki kenaikan kecepatan waktu proses perbaikan kualitas citra sebesar 8.3% dibanding merubah semua nilai pixel citra]]>

<![CDATA[This initial study explores the importance of trust in Aceh tsunami evacuation. Drawing upon the cultural theory as theoretical basis, this research classifies people in Aceh based on their trust level and identifies the significant factors influencing them to trust to different sources during tsunami. To accomplish the goals, an offline survey to 62 respondents in Aceh who experienced tsunami was conducted. From this survey, it found that most of respondents tend to be more trust to their self (individualist) and family/neighbor (egalitarian) than trust to government (hierarchy) and religious leader (traditional). On the other hand, (1) self-efficacy, (2) evacuation knowledge and (3) trust level to non-government people are indicated as the significant factors influencing people to trust in different sources during tsunami evacuation. This initial result will be benefit to develop a predictive model of trust using Agent-based model and simulation (ABMS) for the further research.]]>

<![CDATA[The increasing of the vehicles flow on Yogya-Solo street causing congestion at some points in the Klaten district. The main cause of the congestion is the number of traffic violations which lead to the accidents. Bendogantungan, south Klaten, is one of the most congested point in this district. This study is aimed to determine the causes and the effects of traffic light violations and to examine the difference o f traffic light violations based on the point of violations in the intersection of bendogantungan, Yogya-Solo street. The results show that the practical mind-set of Klaten community in driving has created an instant community. Many people of that community have not realized yet on the importance of traffic regulation, this causes the number of accident. The result of analysis using SPSS 15 shows that there is a significant difference between the one way traffic violation at Empu Sedah street and eastward of Yogya-Solo street. The difference also appears between the one way traffic violations at Empu Sedah street and the westward of Yogya-Solo street. It also happens between the right turn of Ki Ageng Pandanaran street and the westward of Yogya-Solo street.]]>

<![CDATA[Tower is a structure vertically designed that the blades and other components attached. The process for structural design for the tower starts by identifying all of the requirements, and then specifies the desired design criteria. The desired design criteria are high strength, low cost, lightweight, does not require a large area, ease of assembly and transport. The proposed tower types are guyed, lattice, and tubular. The analysis result shows that the lattice tower type matches with the design criteria. The next processes are modeling and stress analyzing using MSC Patran/Nastran. The maximum stress is 42 Newton per milimeters square and the Margin of safety (MS) value is 7.815, so the structure is safe. In the process of making the composite sandwich wind blades, it is starts with the creation of the master molding, mold, foam cores and assembly. The results of the three blades were made indicate by a difference in weight. It is caused by the manufacturing system (manual). However, the difference is still relevant or good because it is less than 5 percent.]]>
