Selection of houses needs to be done in order to get the best alternative houses that match the criteria of prospective buyers, selection of houses based on many aspects such as price, land area, house space, public services, environment, location, road access, facilities and other aspects. Therefore, in this study, a web-based decision support system application was built to decide the best house based on decided aspects. The decision support system was built using the SMART (Simple Multi Attribute Rating Technique) method. This method has a working method based on the theory that each alternative consists of several criteria that contain a number of sub-criteria that have a value and each criterion has a weight to describe how important its value is compared to other criteria. The results obtained in this study are the obtaining of the best house alternative based on the criteria and weight values that have been determined by the user using a decision support system that has been built. Keywords: House, Decision Support System, SMART, Web, Criteria

Abstract

Internet technology is a technology that is currently widely used by humans to communicate and send various data over long distances quickly. In the process of sending data and communication on internet technology can not be separated from the path used, the shorter the path used, the faster the data sent, so communication will be easy. A computer network is a collection of a number of devices in the form of computers, hubs, switches, routers and other network devices that are connected to each other using certain communication media. The author designed the PUTR office in Gunungsitoli City to assist the process of work, especially on the network so that every job runs well without any disturbance.
