Abstract

Good applications and information systems have an attractive interface that is easily understood by users. A good system must also be widely accepted and used by all users. Analysis of the level of effectiveness of UI/UX information systems has been using various types of different methods so that it takes a relatively long time to learn each method that is most suitable and effective. Therefore, this study aims to analyze the level of effectiveness and efficiency of the interface and user experience (UI/UX) of information systems based on various types of methods that are generally used. The method used in this research is the literature study method, by exploring and analyzing previous research related to the measurement and analysis of UI/UX in the context of information systems. The results of this research show that the level of effectiveness of UI/UX of information systems can be measured quantitatively, accompanied by statistical analysis that reflects the level of effectiveness of the 5 commonly used methods in general. In addition, this research also shows the obstacles faced in improving the effectiveness of UI/UX in information systems, as well as the importance of paying attention to good UI/UX so that users are comfortable and can easily use the system. The output of this research can provide new insights related to how much the level of effectiveness of UI/UX on information systems. And can be a reference for other studies in choosing the appropriate UI/UX effectiveness measurement analysis method.

Abstract

Denpasar as a rapidly growing city needs good traffic (road ways, bridges and traffic lights) inventory. However, in actual fact, at present the government agents in charge are still using graphical data in the form of maps and manual information data (blueprints and paper) which results in various problems. Some of the problems include problems in data storage since the map and information data available at present are saved using paper media which would not last very long and easily damaged, problems in planning the maintenance of road ways, bridges and traffic lights because of the relatively long time spent to check the condition, last maintenance time, and associating acquired data with the maps, which could take half a day (according to the amount of data searched) since the checking of data is done manually and separately (disintegrated) from the information data in the maps. Furthermore, manual data checking has a low level of accuracy, since there could be data skipped in the checking process. To overcome the problem of traffic inventory (road ways, bridges and traffic lights) in Denpasar, a GIS-based System (Geographical Information System) is designed and made in this final project, which could deliver information on road ways, bridges and traffic lights in Denpasar in detail. This system would give solutions to the problems such as digital (softcopy) and integrated map data and information data storage so that the map data will last longer and not easily damaged (not including the condition of force majeure), decision making in planning the maintenance of road ways, bridges and traffic lights could be made faster since the checking of the condition, last maintenance time and map marking is done by the system to the integrated data and takes just a few seconds to complete. Moreover, data checking done by the system will have relatively high accuracy, as there would be no data skipped in the checking process
