Abstract

The purpose of this research was to develop a database application at dr. Jonni clinic which can be used for processing and recording of operational data with an attractive user interface. Through the integrated database application, data on dr. Jonni clinic would be more structured, therefore data retrieval will go faster and more accurate, data security administration will be increased, data redundancy will be eliminated and service performance clinic dr. Jonni will also be increased. The method of analysis includes the study of literature, examination of documentation, observation, and interviews. While in the design, the method includes application design using the waterfall method models, database design and data modeling application screens using State Transition Diagrams. The results achieved from this research is an application of data base management hospital. With database applications, all data and information can be integrated well, so that it would improve the quality of  services as well as facilitate storing and accessing data. The conclusions obtained from this research is the application of data base management hospital helps in generating quick and accurate information that is used to support operations and decision-making in the clinic dr. Jonni.

Abstract

Play is something important for children development. In fact, there are many children who can not play as they should. Even playgrounds provided tend not to be able to function optimally. Even there is a tendency of provided playgounds abandoned by children. One example is the generation Z, highly technologyliterate children or called net generation. They would rather to interact with computers and communicate with the online system than meeting their friends. It seems to the generation Z that space is not limited by physical things, because they can create their spaces in the virtual status. Noting this indication, the existence of parks and playgorunds provided for public (including children) to do any activities, is likely to be reviewed. The low level of children visit illustrates that parks/playgrounds do not much interest them.

Abstract

This paper is about designing and implementing data warehousing and data mining, along with their roles in supporting decision-making related to sales product analysis in cross-selling concept of PT XYZ. The database the company used is not supporting data analysis and decision-making. Therefore, it made a data warehousing design that could be used to keep data in a huge amount and could give report and answer from user’s questions in ad hoc. The method is used to design and implement data warehousing and data mining which consists of literature study, company problem analysis, and data warehousing design, and testing result. The writing results are a data warehousing design and data mining and also the implementation of cross-selling concept to analysis the sales, purchases, and customers’ cancellation data. The data could be showed and analyzed from some point of views that could help managers to analyse and acknowledge more information.

Abstract

Along with the times, information retrieval is no longer just on textual data, but also the visual data. The technique was originally used is Text-Based Image Retrieval (TBIR), but the technique still has some shortcomings such as the relevance of the picture successfully retrieved, and the specific space required to store meta-data in the image. Seeing the shortage of Text-Based Image Retrieval techniques, then other techniques were developed, namely Image Retrieval based on content or commonly called Content Based Image Retrieval (CBIR). In this research, CBIR will be discussed based on color, shape and texture using a color histogram, Gabor and SIFT. This study aimed to compare the results of image retrieval with some of these techniques. The results obtained are by combining color, shape and texture features, the performance of the system can be improved.

Abstract

This research has been produced a function prototype of video streaming with JPEG/MJPEG picture quality in a residential security system using mobile device (cell phone). The security system is an early warning system which server will deliver text messaging to client if there is an event in the censor of home webcam to detect movement. The prototype is divided into two types, server and client. The client will be installed a mobile application that automatically activated if there is inbound message in specific port. Meanwhile, the application in user client is completed with functionality to visit particular webpage, one touch call to security phone numbers to do setting (previous research result). And, as the research objective this year, user will see the video streaming in a good quality from the object.

Abstract

Topics and themes become the key to open the insights of both theoretical and practical knowledge in architectural design; a concept in architectural design related issue as well. Ideally, the students of architecture do researches to generate new design ideas or proper design solutions. Prior to doing researches, it is necessary for them to find out how far the process of searches – literature review and application of topics and themes in the architectural design – have been done. This study was conducted with descriptive approach through case studies. The analysis unit is the final students of design studio class and students of the final project in the Department of Architecture, Faculty of Engineering, Binus University - Jakarta. The Results of the study illustrate that the architecture students of Binus University know and learn about the architecture research. However, they need the efforts to improve research skills, accurate literature searches, as well as exercise and evaluation of the implementation of topic-themes that started to be studied by students from the mid-level to theadvance-level. The results of this study will be inputs to support architectural design learning based on architectural research at the Department of Architecture, especially in Binus University.

Abstract

In any city development, it is important to urge people to be involved in so that the development can be valued as much as possible. Model of involvement is certainly diverse, such as 'one-way involvement' in which people tend to just listen, and 'two-way involvement' where the people to participate to make a decision. This paper observes how the public participated in the arrangement of slum area undertaken by the Government. Although there has been community involvement in this activity, there are still any limitations.
