Abstract

This study aims to identify factors that influence students' intention and behavior in using ChatGPT at Mikroskil University. The method used in this study is the Unified Theory of Acceptance and Use of Technology (UTAUT2), with the addition of the curiosity variable. Other variables analyzed included Performance Expectations, Effort Expectations, Social Influence, Facilitating Conditions, Hedonic Motivation, Price Value, and Habit. To collect data, the research team conducted a survey of active students of the Faculty of Informatics at the university. Data analysis was conducted using Structural Equation Modeling (SEM), a method that allows researchers to understand complex relationships between variables. The results showed that several factors had a significant influence on the intention and behavior of using ChatGPT. Hedonic Motivation, Habit, and Curiosity were found to be the main factors driving the intention to use ChatGPT. Facilitating Conditions also contributed to the use of the technology. On the other hand, some variables did not show a significant impact on usage intention. Performance Expectancy, Effort Expectancy, Social Influence, and Price Value fall into this category. These findings suggest that the factors that drive technology use may vary, and highlight the importance of curiosity and personal motivation in the adoption of new technologies in higher education settings.

Abstract

Marketplace Freelance Service adalah platform yang menghubungkan freelancer sebagai penyedia jasa dengan klien sebagai pencari jasa, memungkinkan transaksi layanan secara online. Namun, terdapat tantangan dalam proses pembayaran honor yang kurang efisien, di mana freelancer sering kali tidak menerima honor tepat waktu, sementara klien merasa tidak nyaman membayar penuh di awal kontrak. Selain itu, freelancer tidak memiliki bukti otentik berupa Laporan Penghasilan yang merinci pendapatan mereka, yang penting sebagai referensi melamar pekerjaan atau untuk negosiasi gaji. Penelitian ini bertujuan mengembangkan Aplikasi Mobile Marketplace Freelance Service sebagai solusi atas permasalahan tersebut. Aplikasi ini dikembangkan menggunakan metode Rapid Application Development (RAD) dengan pemodelan berbasis React Native dan Node.js untuk aplikasi mobile, serta React.js dan Node.js untuk aplikasi back-end. Database dikelola menggunakan MySQL. Aplikasi yang dihasilkan mendukung tiga jenis pengguna: freelancer, klien, dan admin, sehingga menciptakan ekosistem layanan yang lebih efisien dan transparan

Abstract

Background: The debate over the superiority between UTAUT and UTAUT 2 has driven the development of UTAUT 3. However, this latest model is still not the best solution, as several variables remain less influential. Objective: This study aims to determine which UTAUT model is superior in technology acceptance, particularly for m-commerce and m-banking. Methods: Multiple linear regression was used to determine the direction and magnitude of the influence of independent variables on the dependent variable, analyzing key factors affecting the adoption of mobile banking and m-commerce by comparing UTAUT and UTAUT 2. Results: In m-commerce, UTAUT highlights behavioral intention and facilitating conditions, while UTAUT 2 adds habit and price value as key influencing factors. Conclusion: For m-banking, both models are equally effective, but UTAUT 2 is superior due to the strong influence of habit. In m-commerce, UTAUT 2 is also preferable, as price value significantly affects behavioral intention.

Abstract

Mental health issues among Generation Z are rising, with depression being one of the most significant challenges. Leveraging the capabilities of big data analytics and artificial intelligence, this study proposes a hybrid method combining Self-Organizing Maps (SOM) and Long Short-Term Memory (LSTM) networks to predict depression risk based on behavioral data. The SOM algorithm is utilized for clustering high-dimensional input data to uncover hidden patterns, while the LSTM network is employed to capture sequential dependencies over time. Data were collected from various digital platforms, processed, and analyzed to train and validate the proposed model. Results show that the SOM-LSTM framework significantly improves the accuracy and reliability of early depression risk detection compared to conventional models. This study contributes a scalable and adaptable model for mental health prediction that can assist in timely interventions for Generation Z

Abstract

The rapid growth of digital streaming services has increased the importance of user experience, particularly in terms of usability. This study aims to analyze and compare the usability of Vidio and Netflix using the Post-Study System Usability Questionnaire (PSSUQ). A quantitative approach with a cross-sectional survey design was employed involving 400 respondents who had experience using both applications. The PSSUQ instrument consists of 16 items measuring four main dimensions: Overall, System Usefulness, Information Quality, and Interface Quality. The results indicate that Netflix demonstrates better usability performance than Vidio, with an Overall score of 2.0506 compared to 2.2236. In terms of System Usefulness and Information Quality, Netflix performs better in system efficiency and information presentation. However, Vidio shows competitive performance in Interface Quality due to its simpler design and better alignment with local user preferences. These findings suggest that usability is influenced by both system performance and interface design. This study provides insights for developers to improve user experience through a balanced approach between technical performance and user-centered design.
