Abstract

Sentiment analysis has become an important approach in understanding user opinions towards digital applications, especially on review platforms such as the Google Play Store. This study aims to compare the performance of three popular classification algorithms, namely K-Nearest Neighbor (KNN), Support Vector Machine (SVM), and Naive Bayes, in classifying sentiment in Traveloka application reviews. The methods used include collecting user review data from Google Play, preprocessing stages such as tokenization and stopword removal, and applying the three algorithms to the cleaned data. The evaluation was carried out using accuracy, precision, recall, and f1-score metrics. The dataset used consisted of 5000 review data that were evenly divided between positive and negative sentiments. The results showed that the SVM algorithm provided the best performance with an accuracy of 88%, followed by Naive Bayes at 86%, and KNN at 87%. The conclusion of this study states that SVM is more reliable in handling text-based sentiment analysis in the context of mobile application reviews. These findings are expected to be a reference in developing a more accurate sentiment analysis system for business needs and future research.

Abstract

The high cost of ICT investment is often an obstacle to ICT implementation, especially for educational institutions with limited budgets. Without analysis, the risk of budget waste and incompatibility with the real needs of the institution becomes higher. This study aims to assess the readiness of information and communication technology (ICT) investment using an integrative approach that combines Cost-Benefit Analysis (CBA), Technology-Organisation-Environment (TOE) Framework, and OODA Loop. This approach is designed to provide a comprehensive evaluation of economic, technological, organisational, and decision-making dynamics in ICT investment. The research method uses a qualitative approach with data collection through observation, interviews, and documentation studies. The analysis is carried out by integrating the results of CBA to assess the feasibility of investment, the TOE Framework to identify factors influencing technology adoption, and the OODA Loop to understand the iterative and adaptive decision-making process. The research findings indicate that based on the CBA analysis, the ICT investment in the form of developing and implementing an e-learning system at SMAN 01 Sanggau is highly feasible to execute. However, from the TOE Framework perspective, the organisation's readiness to adopt the e-learning system is still partial with some shortcomings. From the OODA Loop perspective, the investment is deemed feasible after considering: financial calculations showing benefits through metrics such as NPV, ROI, and PP, non-financial benefits such as improved access to learning and educational quality, and proactive risk mitigation against technical, financial, and operational challenges.

Abstract

A facial recognition-based security system for filing cabinets using ESP32-CAM and the face-api.js library is designed as a modern solution to enhance the security of storing important documents in office or organizational environments. This system utilizes facial recognition technology as a biometric authentication method, offering greater reliability compared to conventional systems. The ESP32-CAM serves as the device that captures users' facial images in real-time and transmits them to a web interface for further processing. Facial detection and feature extraction are performed using the face-api.js library, built on top of TensorFlow.js, leveraging deep learning techniques based on Convolutional Neural Networks (CNN). The models employed include TinyFaceDetector for face detection, faceLandmark68Net for determining facial landmark points, and faceRecognitionNet for generating a 128-dimensional face descriptor. Registered facial data is stored in a web-based database, allowing significantly greater storage capacity compared to local storage in the ESP32-CAM's memory. Verification is conducted by comparing the detected face descriptor against stored data using the FaceMatcher algorithm with a threshold of 0.6. Testing results indicate that the system can accurately recognize faces under adequate lighting conditions, although performance decreases under low-light intensity. This integration of hardware and software provides a more efficient and modern security solution.

Abstract

Advances in information technology have prompted universities to utilise digital systems in administrative processes, including the admission of new students (PMB). Universitas Widya Dharma Pontianak has developed a PMB website as an online registration tool, but no systematic evaluation of its usability has been conducted. This study aims to analyse the usability of the PMB website using the System Usability Scale (SUS) method. The study employs a quantitative approach, distributing SUS questionnaires to 294 respondents selected via simple random sampling from a total population of 1,102 prospective new students for the 2025/2026 academic year. Data were analysed by calculating each respondent's SUS score, then determining the overall average score and its interpretation based on SUS standards. The results showed that the PMB website achieved an average score of 93, which falls into the “A” grade category, an “acceptable” acceptance level, and an “excellent” adjective rating. These findings indicate that the PMB website has a very high level of usability, is easy to use, and provides high satisfaction for users. However, the study also recommends further development regarding improved accessibility and interactive features to support a broader user experience.

Abstract

University websites play an important role as a means of disseminating information, providing administrative services, and facilitating interaction between the academic community and the public. This study aims to evaluate the performance of the XXX University website through a combination of WebQual 4.0 to assess user perceptions and performance testing to measure technical performance. The research method used is quantitative with a descriptive and experimental design. Perception data was collected through a WebQual questionnaire involving 170 respondents selected using purposive sampling. Descriptive analysis was performed using the Respondent Achievement Rate (TCR) formula, while performance testing was carried out using GTmetrix to measure performance score and speed index parameters. The results showed that the quality of the website service based on user perception was in the very high category with an average RAC of 93.6%, especially in the dimensions of usability (94.1%) and service interaction (93.9%). However, the dimension of information quality received a relatively lower score (92.8%), particularly in the indicators of relevance and depth of information. On the other hand, the performance testing results showed suboptimal technical performance with an average performance score of only 15% and a speed index of over 11 seconds, far from the ideal standard of <3 seconds. The website performed better in the morning than at night, indicating server capacity limitations and the impact of traffic load. The results of this study conclude that the XXX University website is considered superior in terms of service quality based on user perception, but is still weak in terms of technical aspects. Therefore, comprehensive improvements and continuous monitoring are required. The combined approach of WebQual and performance testing has proven to be effective in providing a comprehensive overview of the strengths and weaknesses of the website as a basis for further development strategies.

Abstract

Students as Generation Z or millennials are not only consumers but also agents of change in the adoption of financial technology. However, research exploring their behaviour based on the UTAUT framework is still limited, especially in the context of XYZ University. This study aims to analyse the factors that influence the behaviour of fintech usage by students at XYZ University using the Unified Theory of Acceptance and Use of Technology (UTAUT) framework, which is expanded with the variables of trust, perceived security, and financial literacy. The research method used was a quantitative approach with a survey technique involving 185 student respondents who had used fintech services, which were then analysed using Partial Least Square–Structural Equation Modelling (PLS-SEM). The results show that performance expectancy, effort expectancy, social influence, trust, perceived security, and financial literacy have a significant effect on behavioural intention, while facilitating conditions do not have a significant effect on intention but have a positive effect on actual use. In addition, behavioural intention is proven to be the main predictor of actual fintech use by students. These findings confirm that benefits, convenience, trust, security, and financial literacy are key factors driving fintech adoption, while infrastructure serves as a facilitator of actual use. This study has practical implications for campus administrators, fintech service providers, and regulators to increase adoption by providing real value, simple interfaces, applied financial literacy, and strengthening security and trust aspects.
