. ChatGPT is one of the growing innovations in artificial intelligence (AI) technology in the field of education, aiming to assist humans in finding information and completing work efficiently. However, students' lack of understanding of the positive uses and benefits of ChatGPT as a self-learning medium results in low adoption rates and underutilized learning potential. Therefore, this study aims to understand the level of acceptance and the impact that influences students in adopting ChatGPT technology so that it can provide direction and recommendations for schools to increase their self-learning awareness through the utilization of AI. The study used a quantitative approach and interviews with public high school students with the construction of the UTAUT 2 model as a framework. The population of public high school students was 3,405, probability sampling was used as the sampling method then the data was processed using SEM analysis using SmartPLS 3.2.9 software.

With the rapid development of technology, its use has expanded to all sectors, including education. Artificial Intelligence (AI) plays an important role in providing innovative solutions, mimicking human intelligence, and potentially replacing human roles in several functions. In education, AI has proven to enhance learning motivation and active student participation. YouChat, an AI chatbot based on GPT-3.5, is used as a learning assistant offering features such as answering questions and providing idea suggestions. Observations and literature studies show that this application has great potential to improve students' learning experiences. This thesis aims to evaluate the acceptance of the YouChat application on students' learning experiences in public higher education institutions in Surabaya using the Technology Acceptance Model (TAM). Data were collected from 399 students and processed using the SEM-PLS technique with SmartPLS 3.2.9 software, including outer model, inner model, and hypothesis testing. The thesis results show that perceived enjoyment and perceived informativeness significantly affect attitude, which in turn affects the intention to use. The variable trust also moderates the effect of perceived informativeness on attitude. This thesis provides insights into students' acceptance of the YouChat application in their learning process as an evaluation for improvement, development, and enhancement for both YouChat and educational institutions.

The development of AI is having a significant impact on education. AI applications are designed to improve student understanding, but their implementation faces challenges that affect user acceptance. Initial research with the UTAUT2 model in public high schools showed that only hedonic motivation, habit, facilitating conditions, and behavioral intention had a significant influence on application acceptance and use. Therefore, this study will use a simplification model that focuses on significant variables, namely hedonic motivation (HM) and habit (H) on behavioral intention (BI), as well as facilitating conditions (FC), habit (H), and behavioral intention (BI) on use behavior (UB). This study is expected to provide in-depth insight into the important factors that influence the acceptance and use of AI applications in learning, as well as provide practical contributions to improve the implementation of learning technology in high schools.
