Abstract

E-government is an effort to utilize information and communication technology especially internet to improve public service quality which generally implemented in a web based application. Usability is one of the important quality criteria for the success of a web. In this study we developed a framework for evaluation of usability in e-government consisting of  eight stages: (1) determining the evaluation objectives, (2) determining the usability aspects, (3) determining the metrics usability, (4) selecting usability evaluation method candidates, (5) determining the required criteria of the method to be evaluated, (6) evaluating the method, (7) selecting and making the instrument, and (8) evaluate usability.. The results of the application of this framework in the case study of e-finance resulted in two methods used: user testing and questionnaires. The evaluation of usability in e-government for e-finance case studies using the proposed framework results in usability level of e-finance in terms of effectiveness, efficiency, and user satisfaction are 96%, 92%, and 70 respectively. Which can be identified to be grouped into 16 problems consisting of aspects of effectiveness and efficiency.

Abstract

Increasing the use of electricity resources can lead to an energy crisis, so efforts are needed to make efficient use of these resources. Malang State Polytechnic is one of the educational institutions that needs electrical energy to support learning activities. Based on the total number of students more than 10,000 so that the electrical power used daily can be categorized as very large. Along with the development of information technology that is increasingly rapid, it is possible to build an application to monitor the use of electricity resources so that it is expected to minimize the use of electrical energy that is not so important. This study using the Fuzzy Tsukamoto and Raspberry PI methods for monitoring and profilling light conditions. Input variables used are light and time which consists of five linguistic values. This research was implemented in 2 laboratory rooms at Malang State Polytechnic. The Raspberry Pi can monitor the light intensity in a room using two inputs, namely light and time, then the inoutan will be processed using fuzzy inference to get a very low, low, medium, high, and very high output score. So that the light intensity intensity monitoring system in this study can be used to conduct the conditions of the use of electrical energy, especially the power of indoor lighting. Keywords : Fuzzy Tsukamoto, Light, Monitoring, Profilling, Raspberry Pi
