Abstract

Diabetes Mellitus (DM) is a chronic disease characterized by the body's inability to metabolize carbohydrates, fats, and proteins, resulting in increased blood sugar (hyperglycemia) due to low insulin levels. Diabetes is due to a combination of heredity (genetics) and unhealthy lifestyles. Hemoglobin A1c is a blood test used to diagnose and manage diabetes patients when measuring blood sugar levels. This study aims to analyze predictive models for the classification of people with diabetes using R Shiny and evaluate the results of the support vector machine method's classification performance. There are many ways to diagnose diabetes, and the support vector machine is one of the machine learning algorithms used in this study's classification case (SVM). This study uses data from Diabetes 130-US Hospital For Years 1999-2008, which was sourced from the UCI Machine Learning Repository and consists of 34 variables and 84900 records, with dataset distribution and testing techniques using the 10-fold cross-validation method and three kernels in modeling using SVM, namely linear, Gaussian, and polynomial. The results obtained are a simple predictive model analysis system for classifying people with diabetes with shiny, making it easier for users to find out the prediction results and obtain the highest accuracy result, which is 82.76 percent of the gaussian kernel.

Abstract

The information system at FMIPA Unila (Faculty of Mathematics and Natural Sciences, University of Lampung) is intended to support both academic and non-academic activities within the FMIPA Unila community. However, the system frequently faces disruptions, ranging from server shutdowns to unauthorized access by malicious individuals. Furthermore, some of the information service menus and features are currently inaccessible within the FMIPA Unila information system. The main aim of this study is to evaluate the operational efficiency of the FMIPA Unila information system from the user's point of view. The research employs the Information Systems Functional Scorecard (ISFS) method, which comprises three assessment dimensions: system performance, information effectiveness, and service performance. To gauge system performance, questionnaires were distributed to 100 student participants who represent various departments at FMIPA Unila. According to the ISFS calculations, the overall performance of the Unila FMIPA information system can be generally deemed satisfactory. Recommendations for improving and fine-tuning the FMIPA UNILA information system include the provision and completion of information services currently missing from the Profile menu, Academic menu, Research and Service menu, Student Affairs menu, and Document menu. Furthermore, enhancements should be made to the system's menu navigation features and menu buttons to ensure their proper functionality.
