Abstract

Artajasa as a real-time online transaction service provider faces the challenge of monitoring transaction traffic and identifying transactions that are allowed or not. This community service activity aims to create a web-based application to help analyze alerts from the detection system that was previously carried out manually. The implementation of activities consists of interviews and observations, data collection and processing, application analysis and design, application testing and implementation. With the Naïve Bayes algorithm, the prediction results from the historical data obtained an accuracy of 0.88 and the results of the User Acceptance Test showed that all functions had been tried and worked well. With the application made, the work of artajasa's security team becomes effective and efficient because there is no need to check every alert data anymore, but simply focus on the results of the difference between the results of predictions and alerts.

Abstract

AhwalNote is an Islamic mobile app to help depressed people avoid suicide. There is a desire from INDI Technology to improve and add AhwalNote features so that it is assisted in the development of the application with Jakob's Ten Usability Heuristics method. The activity is divided into three stages: the Preparation Stage with observation and interview methods; the Socialization stage with presentation, question and answer, discussion, and practice methods; and the Evaluation Stage is the assessment stage of the development results using the Severity Ratings method. The results of these activities are measured by comparing the evaluation results between the old and the new version of AhwalNote shown with the Severity Ratings value. There are some improvements in the quality of AhwalNote's UI/UX or Usability as a result of the development team of INDI Technology. Furthermore, Jakob's Ten Usability Heuristics method can be applied at the time of development of an application so that the final result before it is released is not too far from the standard usability.

Abstract

In the rapidly evolving digital era, leveraging advanced technologies to enhance the online shopping experience has become crucial, especially for small and medium-sized enterprises (SMEs) aiming to compete in the global market. This research focuses on optimizing the shopping experience by integrating Augmented Reality (AR) and Payment Gateway technologies into a storefront platform specifically designed for women's clothing SMEs. The study begins with a comprehensive analysis of market trends, customer behavior, and the challenges faced by SMEs in adopting these technologies. A detailed literature review provides the foundation for developing a robust conceptual framework. The prototype development phase involves designing 3D models using CLO | 3D Fashion Design Software, converting these models into AR experiences with Meta Spark Studio, and integrating the Midtrans Payment Gateway using Laravel. The AR feature enables users to virtually try on clothes via Instagram, while the Payment Gateway ensures quick and secure transactions. The final phase involves rigorous functional and substantive testing, focusing on user experience, transaction efficiency, and overall system performance. Results demonstrate that the integrated prototype significantly enhances the shopping experience, providing seamless AR interactions and efficient payment processing. Users reported high satisfaction levels with the system's usability and security. The study concludes that integrating AR and Payment Gateway technologies into SME storefronts can substantially improve their competitiveness in the digital market, offering practical insights and guidelines for future implementations in the e-commerce sector.

Abstract

This study focuses on addressing the challenges of processing hand sign data in Virtual Reality environments, particularly the variability in data length during gesture recording. To optimize machine learning models for gesture recognition, various padding techniques were implemented. The data was gathered using the Meta Quest 2 device, consisting of 1,000 samples representing 10 American Sign Language hand sign movements. The research applied different padding techniques, including pre- and post-zero padding as well as replication padding, to standardize sequence lengths. Long Short-Term Memory networks were utilized for modeling, with the data split into 80% for training and 20% for validation. An additional 100 unseen samples were used for testing. Among the techniques, pre-replication padding produced the best results in terms of accuracy, precision, recall, and F1 score on the test dataset. Both pre- and post-zero padding also demonstrated strong performance but were outperformed by replication padding. This study highlights the importance of padding techniques in optimizing the accuracy and generalizability of machine learning models for hand sign recognition in Virtual Reality. The findings offer valuable insights for developing more robust and efficient gesture recognition systems in interactive Virtual Reality environments, enhancing user experiences and system reliability. Future work could explore extending these techniques to other Virtual Reality interactions.
