Abstract

This research aims to evaluate the level of student satisfaction with the use of the Academic Information System (STARS) at Satya Wacana Christian University (UKSW) using the PIECES (Performance, Information, Economy, Control, Efficiency, and Service) framework. The research method used was a survey with a structured questionnaire distributed to a sample of students from various study programs at UKSW. The collected data was analyzed using descriptive statistical techniques and the PIECES Framework to measure STARS performance from the user's perspective. The research results show that although STARS has provided good performance in several aspects, there are areas that require improvement to increase user satisfaction. The implication of this research is the importance of using a framework such as PIECES in evaluating information systems to thoroughly understand user needs and perceptions, as well as providing a strong basis for improvement and development of better systems in the future.

Abstract

Chatbots have significantly evolved through innovations in anthropomorphic design features and artificial intelligence (AI), enabling them to assist users across various sectors and activities. However, inappropriate or incompatible anthropomorphic features can reduce user trust and lead to unmet expectations. This study presents a systematic literature review (SLR) following the Kitchenham approach to investigate the influence of anthropomorphic features on chatbots. The literature search was conducted for studies published between 2020 and 2025. The studies were identified using Publish or Perish as a supporting tool to retrieve records from Google Scholar and Scopus, while additional studies were identified through EBSCO and Wiley Online Library. The findings indicate that anthropomorphic design features influence user trust through two primary perspectives: emotional and cognitive. Furthermore, user trust in chatbots with anthropomorphic design features has three positive outcomes. The first is user engagement, the second is user satisfaction, and the third is loyalty and future intention. However, one notable negative consequence is the uncanny valley phenomenon. The findings also reveal that elements such as chatbot personification and communication style play important roles in building user trust. In addition, the integration of brand credibility and AI-supported capabilities into chatbot design influences user expectations, which subsequently affects trust in chatbots. The appropriate application of anthropomorphic design features, combined with the effective use of artificial intelligence, can help manage and align user expectations more effectively.

Abstract

The substantial growth in mobile banking users in Indonesia does not necessarily reflect a high level of customer satisfaction. This phenomenon is particularly evident in the Bale by BTN application, where the high number of downloads contrasts with user reviews on the Google Play Store. This study aims to evaluate the extent to which the application's features accommodate customers' transaction needs, while also assessing navigation efficiency and security through the Task–Technology Fit (TTF) approach. A quantitative survey was conducted involving 43 active users in Salatiga, with a reliability coefficient of 0.70. The survey findings were complemented by direct observation and an analysis of publicly available user reviews. The results indicate relatively high levels of functional fit, with an overall satisfaction score of 4.51, navigation efficiency of 4.40, feature suitability of 4.33, and a security score of 3.39 for the scrambled keypad feature. Nevertheless, these favorable quantitative findings contrast with the researcher's qualitative observations, which revealed difficulties in locating the mortgage (KPR) menu and recurring complaints about persistent bugs on the review platform. These findings suggest that the application's functionality is perceived as satisfactory among student users who frequently use QRIS services. However, technical reliability issues and a suboptimal interface layout remain major obstacles to broader public adoption.

Abstract

Purpose: This study aims to analyze the dominant trends in color and composition within aesthetic photography on Instagram and explore their influence on user interaction, specifically likes and comments. Given the growing role of visual aesthetics in digital marketing, understanding these elements is crucial for content creators, brands, and businesses aiming to maximize engagement. Unlike previous studies that focus on general social media engagement, this research integrates technology-driven qualitative analysis using ATLAS.ti, enabling structured coding and thematic identification of visual elements. Methods: A qualitative content analysis was conducted on 591 Instagram posts tagged with #AestheticPhotography and #VisualAesthetic. Data was collected using Instagram scraping (PhantomBuster), extracting both visual (color palettes, composition techniques) and textual (captions, metadata) elements. The ATLAS.ti software was used to analyze recurring visual patterns and color extraction was performed via Google Colab and Python for accuracy. Result: The results show that natural colors (48.18%) and pastel tones (30.90%) are dominant in aesthetic photography, contributing to higher engagement due to their harmonious and calming effect. Composition techniques such as center alignment (40.51%) and the Rule of Thirds (23.27%) significantly correlate with user interaction, as they align with cognitive load theory and visual perception principles. Additionally, short captions (≤10 words) were more effective in enhancing engagement, receiving 8,876 likes and 4,432 comments on average, compared to longer captions. Novelty: This study bridges the gap between visual aesthetics and computational analysis, using ATLAS.ti to systematically examine social media trends. Unlike previous studies that focus solely on quantitative metrics, this research provides qualitative insights into how color and composition influence engagement. The findings offer practical guidance for content creators, designers, and marketers, suggesting that strong visual composition and color harmony can enhance audience engagement.
