Abstract

Information services for stakeholders in a hospital need to be in good governance. The rapid development of IT has changed the ordinance of people in thinking, bearing, behaving and acting. Advances in technology that are growing exponentially can potentially result in a number of changes to the governance situation in a hospital environment. The research focuses on the modeling of information services function governance in an effort to create competitiveness to help improve the value of profitability and accountability. Based on analysis of the use of information technology, a description was obtained in blueprint draft about the addition of the functional services based on Customer Relationship Management. The method used is descriptive analysis and structured approach which are parts of the System Development Life Cycle (SDLC). Stages include survey and requirement analysis, as well as the design of model systems about business process based on a database system. The result is a research information services governance model.

Abstract

In this research, the image retrieval system is developed to search for images in the collection of images found on the database based on input (query) in the form of sample images provided by the user. The image is represented as a set of region segmentation results. Users of the system decides the object to be searched on the image and label an example of the region to train the system through a graphical interface. For the image retrieval process that contains a specific object, the user opens the image and choose the region containing the object on the system, then the system will rank all the regions in the collection are indexed query class to the collection in the database in the Euclidean distance (L2) of the region in user query and displays the results of the corresponding images from the collection on the database, which is the image that has the highest similarity.

Abstract

The design of an interface model is expected to contribute in creating a system that improves effective and efficient IT Governance. Hospital as a public facility in health field requires an interface system to communicate to stakeholders. Services performance evaluation interface model is one of the fundamental requirements for strategic development of IT Governance in the future. The presence of current cloud computing technology is a solution in supporting operations in the hospital. The challenge is how hospitals can adopt these technologies. An effective strategy derives from services performance evaluation results so that the use of technology can create efficient IT Governance in terms of financial. Mapping business alignment with IT strategy needs to be done especially in the selection of cloud-based service provider outsource. The method used to adopt cloud computing architecture was referenced to one of the IT Governance international standards which is TOGAF ADM. System architecture models include interface design, infrastructure management, classification, definition, and connectivity design. The main components include business architecture, information (data), application, and technology.

Abstract

Nowadays smart phones are essential part in people’s life. People mainly use them to access social media with Facebook as the most visited web site. Many organizations take advantage by promoting their products on Facebook by creating their organization’s page or by joining merchant groups. Nevertheless, the organizations commonly work in bussiness hours, while users/customers access their smart phones almost everytime (day and night). In addition, many organizations do not provide dedicated staff to maintain their bussiness on line.

Abstract

Engineering models design on performance application is expected to contribute to the development of IT governance system in the hospital. Engineering models are developed using a framework standard. As public facility in the area of health, hospital management requires performance services application to identify the needs of stakeholders. Services performance application design require a good step in the preparation thus it takes study of relevant theory. The methods in the study of the theory is the TOGAF ADM approach. The presence of cloud computing technology can support operational activities at the hospital. The challenge is how hospitals can adopt the technology. An effective strategy derived from the results of the services performance evaluation therefore the use of technology can create effective and efficient IT governance from financial positions. The method used in compiling the IT governance strategy is the system architecture which includes interface design, infrastructure management, classification, definition, and connectivity design. The main components include business architecture, information (data), applications, and technologies. The result of engineering models design have shown that hospitals can use it as a standard architecture model based on a structured system with support from cloud computing technology.

Abstract

Cloud computing has existed almost at the same time as when the Internet was introduced to the public. But this term is not as popular as the Internet in many countries, for example in Indonesia. Although cloud computing has been widely used for storages and backups, there are more of its capabilities that have not been explored. This paper aims to introduce the advantages of cloud computing for business, since many small and medium enterprises can not afford to develop their own websites at their local premises. The main reasons for that condition are inadequate fund for the costs and the lack of IT staff to develop and maintain their websites. With cloud computing, those enterprises can compete on the virtual world with small costs.
