Abstract

This research discusses the comparative analysis of the Canny algorithm and Robert's algorithm in edge detection of Bengkulu cloth (Besurek) using the Matlab GUI interface. The selection of these two methods is to consider the balance between the quality of edge detection, noise resistance, and computational complexity. By comparing these two algorithms we can choose the algorithm that suits our needs. The purpose of this research is to make a comparison between the Canny algorithm and Robert's algorithm so as to produce the best algorithm in the edge detection process based on the number of white pixels produced. From the results of the datatest edge detection test totaling 32 images, the results of the percentage value obtained are the Canny algorithm obtaining 96.875% and the Robert algorithm 3.125%. So it can be concluded that the Canny algorithm is better in the process of edge detection based on the number of white pixels produced in each image.

Abstract

Natural Language Processing (NLP) based chatbots are increasingly used in various applications, ranging from customer service to education. One simple yet effective approach to implementing NLP on a chatbot is the pattern-based method, which uses language patterns to understand and respond to user input. This research aims to implement the pattern-based NLP method on a chatbot and evaluate its performance using the BLEU metric. Conversation data is collected and analyzed to identify common patterns, which are then mapped into appropriate responses. Testing was done by measuring the level of bigram match between the chatbot response and the reference response, where the BLEU-2 precision reached a value of 0.75 or 75%. These results show that the pattern-based method is capable of generating relevant responses but still requires refinement to achieve higher accuracy.

Abstract

Sign language is a method of communication that does not use sound but uses physical movements such as hands, body, and lips. One of the sign languages that many deaf people use to communicate is Indonesian Sign Language (BISINDO). This study aims to implement an object detection and image classification model for BISINDO alphabet gestures using the You Only Look Once (YOLO) version 7 algorithm. This research uses video image data consisting of 26 alphabet letters. In this study, three experiments were conducted with different parameter values. Evaluation was carried out using the metrics of mean Average Precision (mAP), precision, recall, and F1-Score. Based on the experiments conducted, the best accuracy was obtained in experiment 1 with parameter values of epoch = 100, batch size = 64, learning rate = 0.001, weight decay = 0.0001, and momentum = 0.9, resulting in mAP@IoU 0.5 value of 0.995, recall 1.00, precision 1.00, F1-Score 1.00. However, it was found that in the application of the model to real-time scenarios, the detection results were not as good as the results obtained during the training process.

Abstract

This study seeks to assess the usability of the Hospital Management Information System (SIMRS) in OKU RSUD Timur through the application of Heuristic Evaluation and End-User Computing Satisfaction (EUCS) methodologies. The implementation of SIMRS began in 2018 with the aim of improving the operational efficacy of the healthcare facility. However, various technical challenges, including system malfunctions and inaccuracies in data entry, continue to hinder the effectiveness of its utilization. The research methodology used is quantitative descriptive, utilizing data collected through a questionnaire distributed to 78 personnel in OKU RSUD Timur. Data analysis revealed that the average user satisfaction score on EUCS was 81.74%, while the Heuristic Evaluation produced an average score of 82.58%. Both evaluative methodologies indicate that the usability of SIMRS can be categorized as commendable, although the Heuristic Evaluation showed slightly superior results. Given these findings, usability improvements can be directed at refining aesthetic and minimalist features, as well as strengthening system controls and security measures. This investigation contributes to the body of empirical evaluations related to the usability of MIS in health care institutions, thereby encouraging improvements in the quality of health information systems.

Abstract

This research aims to improve the efficiency of academic decision-making at Dian Nusantara University by applying data visualization technology using Grafana. Although the Academic Information System (SISKA) has facilitated data collection related to students, lecturers, and the Teaching and Learning Process (TLP), the utilization of these data for analysis and evaluation is still not optimal. The main challenge lies in processing the data comprehensively to produce relevant information for academic decision-making. This research was conducted through several stages, from identifying specific academic data needs through discussions with stakeholders, access and extraction of data from the SISKA database, and data integration into Grafana. Furthermore, the collected data is analyzed and visualized using an interactive dashboard that displays trends, patterns, and anomalies related to student and lecturer performance. The results showed that using Grafana could facilitate understanding of academic data, enabling faster, more precise, and data-based decision-making. Clear and intuitive visualizations also help the university monitor PBM effectively and identify areas that need improvement.
