Classification of the Relationship Between Fruit Consumption and Diabetes Risk Using the Naïve Bayes Algorithm

2026-03-01T08:56:01+00:00

Diabetes is a non-communicable disease whose prevalence continues to rise, where dietary patterns, including fruit intake, contribute to diabetes risk. This study classifies the relationship between fruit consumption and diabetes risk using the Naïve Bayes algorithm. The dataset consists of 400 synthetic records with 8 attributes. Data preprocessing included cleaning, normalization, and 5-Fold Cross Validation. Results show accuracy of 96.25%, precision 100%, recall 57%, and F1-score 0.73. The model was implemented into GlucoSense, a web-based system providing real-time diabetes risk predictions. This research proves that Naïve Bayes is effective for classifying diabetes risk based on fruit consumption patterns.

2026-03-26T09:39:11+00:00

This study aims to analyze the level of participation in the 2019 elections in Pamekasan Regency based on demographic data using the Naive Bayes classification method. The data used consisted of 189 instances and 208 predictor attributes obtained from the Central Statistics Agency (BPS) publication. The analysis process involved preprocessing, feature selection, and model evaluation stages. The test results showed a model accuracy of 66%, with the highest f1-score value in the high participation class. Further analysis also shows that most subdistricts and villages in Pamekasan have high participation rates. In addition, a very strong correlation was found between demographic attributes that have the potential to be important predictors of voter engagement. These findings provide an initial overview to understand the factors that influence community participation in elections.

2026-03-26T09:46:11+00:00

In this study, the researchers found a way to help teachers input student grades and achievements. Currently, records are still kept in books, which can cause problems such as burning, deterioration over time, or damage caused by pests. The purpose of this study is to create a system that can be a solution to the above problems, which will also make it easier for teachers to monitor their students so that they can report to the students' guardians. The researcher hopes that this system can help in monitoring student development. Blackbox testing was conducted to show that all features functioned as expected. In addition, a user survey was conducted, which showed a satisfactory rating of 60%, particularly for the interface design. However, the system performance still needs improvement because errors occurred in several aspects and received a low satisfaction rating of less than 50%. There are still many shortcomings in this research that need to be addressed. Hopefully, future research can improve on these shortcomings, resulting in a useful project.

2026-03-26T09:50:55+00:00

The main role of Information Technology in today's society is very dominant, and its development is happening rapidly. This technology allows us to quickly and accurately access and process information. In this case, the Sidodadi Community Health Center, located in Sidoarjo Regency, has made efforts to improve the efficiency of outpatient registration. Currently, the patient registration system is still manual, which results in long service times. This study aims to present an innovation by developing a web-based registration system. This application simplifies and optimizes the queuing process, both for users who want to take a queue number and for administrators who call queue numbers. The use of web-based technology is the right solution to improve service quality. This study has limitations in that the application development is only focused on the Sidodadi Community Health Center, Sidoarjo Regency. The main objective of this study is to produce an efficient web-based patient queue number registration application. This application will improve the patient experience, facilitate more structured queue management for Community Health Center staff, reduce patient waiting times, and provide accessibility for patients to monitor their queue information online. The method used in this study is the waterfall method, which has five stages, namely communication, planning, modeling, construction, and deployment. The application development methodology involves needs analysis, system design using the programming languages used in this study, namely PHP, HTML, CSS, and JavaScript, web-based application development, testing, and evaluation. The test results showed that the system successfully provided queue numbers in accordance with the correct queue order, and the user interface was easy to use. This study concluded that the development of the Sidodadi Community Health Center Web-Based Patient Queue Information System successfully improved the efficiency of patient registration and improved the quality of services at the Community Health Center.

2026-03-26T09:57:19+00:00

This test was conducted to assess the performance of the information system of the Language Center at Muhammadiyah University Sidoarjo using the COBIT 5 DSS domain framework. The audit aimed to evaluate the reliability and efficiency of the system in addressing operational issues such as limited website access and failure to print TOEFL certificates. Data collection involved interviews with unit leaders and technical observations. The results showed varying maturity levels from 2.1 (DSS03) to 4 (DSS06). Critical findings included the absence of a ticketing system and backup automation. Recommendations focused on implementing centralized incident management and cybersecurity training. This study provides a governance model for optimizing language service systems in higher education institutions.
