Abstract

The development of digital gold-based financial services in Indonesia has shown significant growth; however, the quality of user experience remains a critical factor in ensuring long-term application usage. Although thousands of user reviews are available across various digital platforms, this information has not been fully utilized as a foundation for service improvement. This study aims to conduct an in-depth analysis of user sentiment and generate application development recommendations based on real user perceptions and experiences. The methodology includes collecting a large number of user reviews, performing text preprocessing, and applying sentiment classification using several machine learning models. IndoBERT demonstrated the best performance with an accuracy of 0.88, precision of 0.84, recall of 0.88, and F1-score of 0.86 based on 7,113 test data, indicating strong capability in identifying positive and negative sentiment, although neutral sentiment remains challenging. The analysis reveals that positive sentiment is associated with the ease of investing in gold, intuitive interface design, and overall user convenience. Conversely, negative sentiment is predominantly linked to technical issues such as transaction errors, login disruptions, slow authentication, and system instability. The WordCloud visualization also highlights the dominance of terms such as error, login, and verification. Based on these sentiment patterns, the study proposes several priority recommendations, including enhancing system stability, optimizing authentication mechanisms, refining transaction flows, and strengthening customer support. This study provides a structured mapping of user issues that can serve as a strategic foundation for developing more reliable, secure, and user-aligned digital gold financial applications.

Abstract

The waste problem in Indonesia has reached an emergency condition with an estimated generation of 69.7 million tons by 2025. Although digital solutions are starting to emerge, logistics efficiency in conventional waste collection systems is still a major obstacle. The research aims to design "Seeklus", an innovative self-waste management system that integrates a mobile application with a Trash Vending Machine based on electricity voucher incentives. The method used is Design Science Research (DSR) with the SDLC Prototyping stage, which is supported by SWOT strategy analysis based on data from 150 questionnaire respondents. The results of the study show that the main strategy is focused on utilizing the novelty of the digital incentive system to increase the participation of urban communities. User experience evaluation using the User Experience Questionnaire (UEQ) resulted in very positive scores on the Attractiveness (4.45) and Novelty (4.40) dimensions. These findings prove that Seeklus has successfully offered innovative, efficient, and high user acceptance solutions as part of the smart city ecosystem and circular economy.
