Innovation in mathematics learning technology is a signal in the Society 5.0 era and should ideally be reflected in mathematics education, including in schools in the Pontianak City area. This research aims to analyze the innovation of mathematics learning technology in accordance with the demands of the Society 5.0 era. The research method uses a qualitative-exploratory approach. The research results show that there is still a gap between the dynamic development of technology and teachers' ability to incorporate technology into their teaching. This gap occurs due to teachers' tendency to prioritize lecture methods, note-taking, and conventional problem-solving exercises. As a result, the innovation of technology in mathematics learning has not been well implemented. In fact, the sophistication of technology through Artificial Intelligence (AI), Big Data, and the Internet of Things (IoT) promises effectiveness and efficiency in learning. That reality serves as a sign that teachers involved in mathematics education need to be motivated and their awareness of innovative capabilities needs to be enhanced, so that the mathematics teaching methods implemented become more modern. Maximizing the potential of technology in accordance with the demands of the current era. Supporting a more adaptive and interactive curriculum. Students can be more active and critical, and can interpret and apply mathematical knowledge in everyday life.

This study aims to identify and analyze students' epistemological obstasles in solving contextual problems of geometric rows and series. The research was based on observations and interviews at Santu Petrus Pontianak Catholic High School which indicated learners' obstacles in solving contextual problems. This study used a qualitative approach with six learners as subjects, who were grouped based on the level of problem solving ability. Data were collected through problem solving ability tests and interviews. Data analysis was conducted using triangulation technique. The results showed that high ability learners did not experience epistemological obstacles. Learners with moderate ability experience obstacles in procedural aspects and operational techniques, such as difficulty choosing formulas and performing calculations. While low ability learners experience obstacles in conceptual, procedural and operational techniques. This research confirms that epistemological obstacles are closely related to problem solving ability. It is hoped that this research will have implications for the development of more effective learning strategies to minimize learners' epistemological obstacles.
