Data collection methods included observation, focus group discussions, documentation, and interviews. Data were validated using member verification and triangulation techniques. Data analysis was conducted using the Creswell data model. The school day at SD Negeri Banyubiru 01 showed that the school day affected school spirit. Some school activities included socialization in class, teamwork and dhuha prayer, and religious education. The two main factors that hinder teacher professional development are cost and time. Teachers must set aside funds for students to participate in classes or programs and time to learn and improve their skills. In addition, a teacher may be able to explain the changes and difficulties in implementing new practices. It can be challenging to carry out professional development activities. Sometimes, teachers cannot fully use the knowledge and skills they have to teach students in everyday life]]>
