Along with the dynamic changes in business environment, information technology strategy map becomes an effective and flexible mechanism to visualize critical strategic actions required for the company and information technology (IT) organization to achieve its objectives. On the other hand, IT is perceived as a center of cost and investment. Therefore, IT benefit values become very important to measure and communicate. Using Balanced Scorecard method, this study aims to design IT strategy map aligned with the corporate strategy and effective measurement of IT performance in its contribution to achieve corporate objectives. The method is designed based on the results of data and information analysis gathered from executive interviews, focus group discussions and workshops at the company. Balanced Scorecard is a comprehensive and effective tools to measure, monitor and evaluate the performance of IT critical success factors (CSFs) to support the corporate objectives.

Ground measurement helps illustrate a situation of land map to ease a civil engineer determining the center point of a building. From the situation map can determined the further works such as determining the point of building, land leveling, determining the point of the foundation and the volume of work for hoarding the land. A tool used for measurement activities is theodolite. Theodolite serves as a tool to determine the angle formed between the two points at the time of measurement. Drawing a situation map requires the results of the point measurement data. Theodolite is divided into two types, digital and manual. This study compares measurements results using both digital and manual theodolite performed at Kijang Campus, Binus University. From the comparison of data processing generated large differences in the coordinate system on the situation map with ranging from 1.31% to 322.67% on the abscissa axis and 0.39% to 41.83% on the ordinate axis.

Use of the Internet at schools grows advanced. Therefore, teachers need to learn the use of technology in creating good teaching materials (learning objects) such as animation-based materials. Those materials will result will in a component in a learning system that allows students to interactively learn and evaluate themselves against the subject mastery. A tool for creating such an animated material like Powerpoint produces presentations enhanced with audio and video that allows students to comprehend the lessons more easily. The model system uses interactive multimedia system design and development with the following phases: (1) system requirements, (2) design considerations, (3) implementation, (4) evaluation. While user interface design principles uses eight golden rules of interface design. As a test case, selected Biology at Yaspia junior high school and Bina Management vocational school. From the results it can be concluded that this application module can support students in obtaining the required data completeness. The tutorials are quite sufficient to facilitate students in understanding the material.

Mobile games develop along with technological developments. Gaming applications by applying special graphics technologies optimizes any mobile device. The purpose of this study is to design an Action RPG game application by applying Cocos2d technology to be implemented on mobile devices based on IOS operating system. This study performs data collecting and analyzing, interface designing, application implementation, and application evaluation using the Waterfall Model. Data collection is withdrawn from several surveys related to user needs and similar games. Progressing the study, gameplay design is performed using UML, the data storage structure, and interface design. The study results in an Action RPG game application that is implemented on mobile devices. The results showes that Action RPG games can be developed by incorporating elements of art, graphics, and stories that enhance user's interests.

This study aims to identify whether the information system used by a sea food restaurant has been efficient and effective. It can support decision making for follow-up actions. The methodology used in this study is literature study, interview, and survey. To evaluate the effectiveness of operational information systems at the restaurant, we use cost benefit analysis. To evaluate whether the operational information system is efficient, we use questionnaire with Likert scale calculations. Based on the evaluation of the effectiveness and efficiency ofoperational information system at the restaurant, it can be seen there is a difference between investment in 2004-2009 and investment in 2010. From the results of calculation using cost benefit analysis to determine the effectiveness, we find that investment in 2004 was positive while investment in 2010 is still negative. Based on the results of questionnaires, the investments are considered efficient. Based on the evaluation, information systems used in sea food restaurant has been effective and efficient. The return on investment only takes less than two years and the information systems supports operational activities.

The term ?vernacular? and ?traditional? in architecture context actually has a root meaning which is almost the same; both have the same meaning that can be attached to one form of architecture work which is oriented on locality aspects and historiy of its existence. However, how can we distinguish the two terms? One way to find it out is to do a case study on two traditional architecture buildings: Balinese buildings and Minangkabau buildings taken as the sample study. In general, both building have two criteria: culture philosophy and adaptative modernism. Through descriptive analytical methods, the two building types were analyzed to acquire the definition of the building shapes which can be classified whether they belong to vernacular or traditional. The results show that vernacular architecture is a form of original work which is specified with the content and a very strong local and contextual philosophy proper to its time, while the traditional architectural building is a vernacular masterpiece recognized by acclamation and hereditary within a very long time.
