Abstract

The research on tile classification using Convolutional Neural Network (CNN) aims to improve and address issues in the sorting process within the tile manufacturing industry. The accuracy level in manual sorting processes is very low due to errors caused by visual limitations and physical fatigue. By leveraging the capabilities of Convolutional Neural Network (CNN), a model was developed to classify tiles. This research involved several processes, including literature review, dataset collection, dataset splitting, preprocessing, Convolutional Neural Network (CNN) design, training, testing, and result evaluation. The study used 69 tile images divided into three classes: KW 1, KW 2, and KW 3. The results of testing the Convolutional Neural Network (CNN) on tile classification using 100 epochs with a data split of 90% training and 10% validation yielded an accuracy rate of 100%.

Abstract

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.

Abstract

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.
