<![CDATA[Earthquakes and tsunamis are natural disasters that can cause significant loss of life and extensive damage, particularly in coastal areas such as Aceh Besar Regency. Schools located in disaster-prone areas need to maintain a high level of preparedness to minimize disaster risks and impacts. This study aimed to assess school community preparedness for earthquake and tsunami disasters at SMA Negeri 1 Peukan Bada, Aceh Besar. This study employed a quantitative method with a descriptive design. The study population consisted of all school community members, including students, teachers, and educational staff. A total of 222 respondents were selected using a stratified random sampling technique. Data were collected using a structured questionnaire and analyzed univariately by presenting frequency distributions and percentages. The results showed that, of the 222 respondents, the majority had a good level of preparedness, comprising 134 respondents (60.4%), while 88 respondents (39.6%) had a moderate level of preparedness. The respondents were predominantly female (60.4%), aged 15–20 years (89.2%), and students (89.2%). Furthermore, most respondents had participated in disaster simulations (76.1%). In conclusion, the school community at SMA Negeri 1 Peukan Bada generally demonstrated good preparedness for earthquake and tsunami disasters. Nevertheless, further efforts are needed to improve preparedness through regular disaster simulations, strengthened disaster education, evaluation of school emergency response plans, and enhanced collaboration with relevant agencies to continuously improve preparedness among all school community members.]]>
