Abstract

To meet the needs of information delivery to be rapid, mobile and safe needed a model calculation of the best antenna location and utilization of transmission media. One model that can be used takes advantages of wireless as well as models Flether-Powell algorithm, which combines mathematics with information technology. The algorithm can calculate the best position of a transmitter with reference of maximum received intensity amount in all the Main Point Coverage. To simplify the calculation process a computer program is developed written in Borland C. the program evaluation results show that by utilizing this application a company can place transmitters better and more effectively.

Abstract

The increasing number of road user causing traffic jam finds out a way, busway. However, in its implementation, the number of fleet available does not enough to take the passengers. It results in the an amassed of passengers at several bus stops. This leads to passenger dissatisfaction satisfaction which eventually causes Transjakarta users to reuse private cars. Definitely this situation may builds up traffic jams. Stochastic Bus Dispatching Model is used to simulate public transportation that operates regularly.

Abstract

Shading device serves as a shade and protection against negative influences caused by the uncertain external conditions. This article discusses the study of kinetic shading system and evaluates its effectiveness against a wide range of environmental factors and their effects on building. The study performs simulation of thermal factors, day lighting, airflow, and energy generation. Morphological types of shading device to be tested are systems of overhang, folded, horizontal louvre, and vertical louvre. The test results demonstrate that kinetic system obtains more advantages and effectiveness than the standard and static systems do. Therefore, it can be concluded that this study is able to be used as a reference for designing kinetic shading device which is responsive to environmental factors.

Abstract

The Catholic diocese of Parramatta is well-known as the first established Catholic Church in Australia. It is the most recently completed Cathedral in Australia, designed by Romaldo Giurgola. As a foreigner, he was successfully applied the historical values and symbols of Catholic tradition shown on the design’s elements and forms throughout the Cathedral. This paper explores the design of the Cathedral Church of the Catholic diocese of Parramatta which is influenced by works of other architects such as Utzon and Van Eyck. The use of natural light and different materials’ quality in the interior and exterior of building are few of the design’s elements applied in the Saint Patrick Cathedral.

Abstract

The architecture curriculum in formal education is necessary to be redefined in order to adapt to computing technology to obtain its good values. CAAD is added to architecture learning with no settled framework; relying on practical experience of lecturers. This reminds of how important the adaptation to the theories and science of architecture that evolved with the advent of digital media is. Therefore, the methodology and teaching approach systems are need to be reviewed, with the help of architects, professionals and the authority to fix the narrow perception of digital architecture. This article is a summary of several earlier studies on the influence of information technology on the education of architecture lately. It is expected that in the future this article may be useful as a theoretical basis for the course Computational Design in Architecture Architecture I at Bina Nusantara University.

Abstract

Japan currently has been successful to provide housing for low to high-income people in urban areas. Almost everyone in Japan can access their homes, either public housing or private one, depending on the level of their welfare status. The study discusses about development of public housing in Japan and why the Japanese people can accept the design of the vertical housing built by their government. The study is conducted with descriptive approach through literature study and field observations in the city of Tokyo and its surrounding areas to provide knowledge about the development of public housing in Japan started from traditional residential and then developed into a modern residential horizontally and vertically according to the needs of his hometown community. Despite of the development from time to time, the design of residence still considers the local culture of Japan. So the Japanese people can receive residential design, although it is developed into vertical housing. This study is expected to give inputs for the Indonesian government as an effort to achieve the successful provision of public housing in Indonesia.

Abstract

The purpose of this study is to analyze the Critical Success Factor of e-procurement implementation, that is able to show the influence factors of successful implementation of e-procurement in companies. This study uses benchmarking method to examine the non-random selected samples from some companies which are advanced in implementing e-procurement including the contextual analysis of issues related to similar situations. From the findings then performed the identification and benchmarking study, mapping towards the successful practice at the companies. Eventually it is concluded that there is no best standard for e-procurement as the factors most affecting successful implementation are non-technical, of which this understanding will be the first step to systematically analyze the supporting factors in implementing e-procurement successfully. Therefore, e-procurement does not only improve the operational performance of the company in efficiency improvement of enterprise's supply chain management process but also provide added value for the company.

Abstract

Web and mobile technology help a lot of business activities since it can be accessed from the Internet and intranet networks so that flow of the information needed can reach out various locations. Web and mobile technology combined with E-CRM technology like helpdesk can be used to improve services. This study aims to design a web-based claim management system (supported with helpdesk system) and its BlackBerry® application for PT. Hoppecke Indonesia. An analysis through literature study and field survey (interview to the employees of PT. Hoppecke Indonesia) is implemented in this study based on the incremental method. The result achieved is a design web-based claims management system and the BlackBerry® application. The design is expected to maintain the relationship between customers and companies, especially in term of item maintenance and to make easy for customers to obtain information that will lead to loyalty to the company. Plus, the documentation of each interaction between customer and the company can be recorded properly.
