Implementation Of The Data Mining Cart Algorithm In The Characteristic Pattern Of New Student Admissions
Get PDFUniversity of Harapan Medan is one of the private universities in North Sumatra which has an Informatics Engineering Study Program with Good Accreditation. With better accreditation, the number of students who register is also increasing. At the admission of new students, the committee has a huge pile of data, making it difficult in the process of whether the student passed or did not pass. Therefore, in this study, we will implement data mining with the CART (Classification And Regression Tree) algorithm. Data mining is a technique to determine the characteristic pattern of a variable or data criteria with a large amount. In the CART method, the data is first converted into testing data, which will then be used to form a classification tree by calculating the value of information gain, Gini index and goodness of split. From the results obtained, it will be re-determined terminal nodes, marking class labels and finally pruning the classification tree which produces a decision tree. In this study, the number of testing data was 75 with 3 criteria, namely the average value of report cards, CAT test scores, and interview scores. The results of testing data testing using RapisMiner 5.3 software produce 23 number of characteristic pattern rules, where node 1 is the CAT test score, level 1 branch node is the interview score criteria and level 2 branch node is the average report card value

Usability Testing On Inventory Application Using Performance Measurement, Retrospective Think Aloud, And System Usability Scale Technique.
Get PDFSystem evaluation is carried out with the aim of knowing system weaknesses that hinder users from implementing them. Inventory application users in Badung Regency, based on interviews conducted, had never been evaluated and there were several records collected regarding complaints from users. This study aims to evaluate the value of the success and speed of doing tasks with Performance Measurement, RTA and SUS Techniques. Based on the results of processing the data obtained with the performance measurement technique, it shows that pages are generally quite effective because they function properly, even though there was an error in one of the tests in carrying out the task by the respondent. This is due to a period mismatch caused by the user's own error, namely forgetting to change the period. Efficiency when viewed from the results of the data obtained with performance measurement techniques, it is generally known that inventory applications are quite efficient. For user satisfaction, the score for the respondent's questionnaire is 61.18 which is obtained, this means that the score is smaller than the SUS standard score, which is 68. So it can be said that respondents are not satisfied using the Inventory Application. The results obtained from the usability testing process show that the Inventory Application page which is the object of research still does not meet the criteria for a product with good usability. This can be seen in the assessment of the level of effectiveness, efficiency, and user satisfaction. This inventory application is not able to meet the good criteria for these three aspects
