Based on the available data, a classification process is carried out using the K-Nearest Neighbors algorithm. Rapid Miner is used to experiment text data with the KNN algorithm in order to find the value of accuracy, precision and recall. From the results of research, it was obtained a value of 87.00% for accuracy and 0.916 for the AUC value.

Abstract

In the User Experience (UX) analysis carried out using the User Centered Design (UCD) approach, the research is based on user-oriented design. A website based on the UCD process will definitely generate high levels of satisfaction for its users. In this research, user experience analysis was conducted using a User Centered Design approach with Product Market Fit concept orientation. This concept is often ignored so that it becomes a major factor in the failure of a business start-up. The collection was carried out through several processes, namely in-depth interviews and distribution of questionnaires to a total of 30 respondents. The results of the questionnaire can be used as a reference to find out which aspects are good and which are still lacking. The aspect of displaying information on the monitor screen when opening a website gets the highest score of the other aspects with a percentage of 93% user satisfaction. The conclusion for each aspect states that the curious websites that are analyzed get a decent title.
