Chikungunya, a viral disease transmitted by Aedes aegypti or Aedes albopictus mosquitoes, poses a significant public health threat. In Wonoboyo Village, according to data from the Wonogiri Health Office, there were 119 reported cases in 2020, and 61 cases in 2021, highlighting the local impact of this disease within Wonogiri Regency. This study endeavors to investigate the factors contributing to the Chikungunya outbreak specifically in Wonoboyo Village. The research adopts an analytical observational approach with a cross-sectional design. The study's variables include the state of the landfill, the presence of larvae, occupancy density, landfill maintenance habits, hygiene practices, and mosquito repellent usage. The dependent variable is the occurrence of the Chikungunya outbreak (KLB Chikungunya). Data collection involves questionnaires and observations among the residents of Wonoboyo Village, with a sample size of 357 households selected through simple random sampling. Analysis utilizing Chi-square tests, with a significance level of 5%, reveals correlations between various factors and the Chikungunya outbreak.
