Abstract

Software evaluation is needed to determine the usability level of the software. Good usability is having the following characteristics: effective to use (effectiveness), efficient to use (efficiency), safe to use (safety), having good utility (utility), easy to learn (learnability) and easy to remember how to use (memorability). Analytical evaluation is one evaluation approach that does not involve users. The evaluation is conducted by experts associated with the product. One method used in the analytical evaluation is GOMS, a method to analyze a task related to human computer interaction. GOMS does not provide accurate calculation of how users interact with the system, yet it estimates the time need to do a task dealing with the system. With the evaluation of UML users are expected to be able to use UML tools that appropriate to particular needs based on open source.

Abstract

This study aims to examine the application of ratio estimators on a sampling method by taking the case of estimating the ratio of critical land of every county around Jratun watershed. Through the estimation, a general description of critical land deployment for each region (county) can be obtained. In addition, the estimator of hose/interval is also determined for the ratio with the real level of 0.05. The simple random sampling method is used in conducting the estimation of ratio of the critical land to the total land area. Theestimation results show that the ratio of the critical land to the total area for 19 districts reaches 23.72%.

Education industry is a service enterprise that has its unique characteristics. Thus, the implementation of e-CRM in education institutions and other service companies is different. The research methodology uses variables Pre-Purchase, At-Purchase, Post-Purchase, e-Trust, e-Satisfaction and e-Loyalty, where the hypothesis was tested by correlation analysis and regression analysis. Besides, it also uses IPA (Importance Performance Analysis) to identify factors to be improved by calculating the gap analysis. The test results obtained show that based on the correlation analysis, all the H1hypotheses (has relationship) are accepted and based on the regression analysis, all the hypotheses H1 (has effects) is accepted. Under the IPA, for both increases in the first priority and second priority, all the variables need to be improved.
