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.

House, yard and neighborhood where a person lives affect his life. As legacy of our ancestors, the use of ancient Chinese knowledge of layouting (feng shui) and ancient Javanese knowledge are an approach of eastern culture that needs to be preserved since they are the result of thousand-year wise and sage ancestral experiences. The combination of Chinese and Javanese knowlege help find natural phenomena in relation to the search for life happiness in harmonious balance. Planning the layout of a building needs the study of the characteristics of local condition and prospective residents. Fengshui as one aspect of the approach to natural alignment is used to deal with unbalanced natural or environmental clues around us, which can affect people's lives physically and psychologically. This study aims to identify the relationship between theories and practices as well as to find out to what extent the benefits of feng shui in the design of architecture. The survey results are analyzed by existing ordinances to get evidentiary between theories and practies. Fengshui and ancient Javanese knowledge are some heritages of ancestors? thousands-year practice in the creating buildings which should be scientifically analyzed and integrated with the science of architecture so that the results obtained will be used in the development of architecture which is useful for occupants.

The use of information technology has been very widely in many fields including industry. Along with that, the need for a concept and mechanism of IT-based learning becomes inevitable. The purpose of this paper is to analyze the training process and identify any related problems occurred at PT.Suzuki Indomobil Motor. The problems are about the limited training time, lack of material distribution media and consultations out of training time. E-Learning is a concept of electronic application use to support learning using the internet and computer network. This concept influences the process of conventional education transformation to digital form, both in content and system. The learning system will be replaced with a web-based training media. The method used is the Object Oriented Analysis Design, which begins with a depiction of rich pictures to the Deployment diagram. This system is expected to meet the needs of employees while joining the training process, so that they will obtain excellent learning and achieve the company objectives.

On electric power system operation, economic planning problem is one variable to take into account due to operational cost efficiency. Economic Dispatch problem of electric power generation is discussed in this study to manage the output division on several units based on the the required load demand, with minimum operating cost yet is able to satisfy equality and inequality constraint of all units and system. In this study the Economic Dispatch problem which has non linear cost function is solved using swarm intelligent method is Gaussian Particle Swarm Optimization (GPSO) and Lagrange Multiplier. GPSO is a population-based stochastic algorithms which their moving is inspired by swarm intelligent and probabilities theories. To analize its accuracy, the Economic Dispatch solution by GPSO method is compared with Lagrange Multiplier method. From the test result it is proved that GPSO method gives economic planning calculation better than Lagrange Multiplier does.

The article explores the influence of database compression on processing time in generating online test results through experimental study. The study uses three level compressions consists of none, row and page in table used by online test system. The experiment shows that using page compression results in faster processing time and less space compared to none and row compression, and the optimal row for compression is between 1001 and 2000 rows. In summary, to reduce space usage and processing time, it is better to use page compression in user answer table of online test system and to group the participant in schedule so that users? answer will be between 1001 and 2000 rows.

The role of knowledge in developing and maintaining an organization has been strongly regarded as a very important asset. Bina Nusantara University is one of the universities that is aware of the importance of book as main knowledge media in the learning process. Reviewing books and sharing the results can be a major resource to perform maintenance on knowledge and accelerate the learning process. A problem that occurs in Bina Nusantara University is no application to do Book Reviews. There are no tools that facilitate discussion between book reviewer and book review reader. The purpose of this research is to design features of Book Review on Knowledge Management System (KMS) in Bina Nusantara University. It is expected that book review features are useful for faculty members and staffs in doing book reviews. The methodology used in this study is literature study and design a KMS application using Microsoft SharePoint 2010 technology. Conclusion of this research is the application of KMS Book Review in Bina Nusantara University can encourage book reviewers and facilitate book review readers to discuss and interact more optimally.

Façade is the front of the building which is facing the street. It is one of the architectural elements of the city that can? speak out? the meaning of the building. In addition, façade is also a part of urban environment order which needs to be sustainable. The transformation of building function often impacts on changes in the composition of façade. Therefore, it is very interesting to be observed, especially along Pakubowono's street, which has distinctively Jengki architectural buildings. The purpose of this study is to explore the the extent of architectural transformation that occurs in Jengki style building by using descriptive methods. The result showed that Pakubowono area has undergone a change and assimilation of forms, although it is not very significant in the building typology. There are many changes that occur in materials and building elements which is an attempt to maintain its damaged parts.
